			<content:encoded><![CDATA[<p>First off, the long awaited PC version of <a href="http://blackmagic-design.com/products/davinciresolve" target="_blank">DaVinci Resolve </a>was released to <a href="http://blackmagic-design.com/support/detail/?os=win&amp;sid=3948&amp;pid=11735&amp;leg=false" target="_blank">public beta </a>last week.  Both the full version and the free Resolve-Lite now have PC variants available.  You can bet I will be setting up a high end PC based system to run it on at work, since that is the only step in our workflow that we currently use a Mac for.  The big question is going to be file format and <a href="http://blackmagic-design.com/media/2588311/davinci_resolve_8.2_supported_codec_list.pdf" target="_blank">codec support</a>.  We currently use DPX and Cineform MOVs for our system in the office, but eventually using Cineform AVIs would fit more seamlessly into our workflow.<br />
<span id="more-325"></span><br />
Unlike with the<a href="http://blackmagic-design.com/media/2384470/DaVinci_Resolve_Mac_Config_Guide.pdf" target="_blank"> Mac version</a>, they don&#8217;t seem to be promoting the idea of using the Lite version on a laptop, instead <a href="http://blackmagic-design.com/media/2554788/DaVinci_Resolve_Windows_Config_Guide.pdf" target="_blank">recommending</a> two GPUs and a full workstation class system as a minimum.  For real-time SDI based HD playback, that is obviously necessary, but there are also benefits to being able to use a more portable system.  I want to learn the software, and ideally would set it up on my Quadro based laptop, but after reading the documentation, I decided to start on my larger workstation instead.  Running it on a laptop will require support for a decent compressed format, and while Cineform currently provides that on the Mac side, the PC version of Resolve does not yet support that codec.</p>
<p>I downloaded the Lite version and have been playing around with it, but it is not a very intuitive program.  I am about fifty pages into the manual, but have yet to be able to get a sequence of content I cut together in <a href="http://www.anrdoezrs.net/click-4107801-10469519" target="_blank">CS5.5</a> into <a href="http://www.bhphotovideo.com/c/product/686594-REG/Blackmagic_Design_DV_RESSOFT_Davinci_Resolve_Software.html/BI/6727/KBID/7302" target="_blank">Resolve</a> successfully.  I can&#8217;t export it into any format Resolve will read, besides uncompressed HD, which my array is not designed to handle.  Using an <a href="http://en.wikipedia.org/wiki/Edit_decision_list" target="_blank">EDL</a> to link to my <a href="http://www.bhphotovideo.com/c/product/583987-REG/Canon_2764B004_EOS_5D_Mark_II.html/BI/6727/KBID/7302" target="_blank">Canon 5D</a> source files is giving me all sorts of issues as well, which is something we experienced at the office when we first switched from Speedgrade to Resolve.  Clearly it is going to take some time to learn how too get anything useful done in the program.  If I do get it to work, the automatic tracking tools are the features I am most interested in playing with.</p>
<p>In other major news that doesn&#8217;t directly affect me, <a href="http://blackmagic-design.com/" target="_blank">Blackmagic-Design</a> also acquired <a href="http://www.teranex.com/" target="_blank">Teranex</a> last week.  The first major change they made was <a href="http://www.teranex.com/company/news/vc100BMDpricing" target="_blank">cutting the price </a>of Teranex&#8217;s primary flagship product, the <a href="http://www.teranex.com/products/vc100" target="_blank">VC100</a>, from $90,000 to $20,000.  This is similar to what happened when they acquired DaVinci last year, but much more extreme.  It will be interesting to see if some of that high end image processing technology makes it into future <a href="http://www.bhphotovideo.com/c/product/746054-REG/Blackmagic_Design_BDLKHDEXTR3DPLUS_DeckLink_HD_Extreme_3D.html/BI/6727/KBID/7302" target="_blank">Decklink</a> cards, or any similar products.</p>

			<content:encoded><![CDATA[<p>I haven&#8217;t posted much in the last few months, because there have not been many new developments that caught my eye or piqued my curiosity.  But this month we are seeing a number of releases that are relevant, and moving the industry forward.  The first one to actually become available to users is <a href="http://www.avid.com/" target="_blank">Avid&#8217;s</a> release this morning.</p>
<p>After announcing it last week, today Avid released the next version of <a href="http://www.avid.com/us/products/family/media-composer?intcmp=AV-HP-S2" target="_blank">Media Composer</a>, and it is a major update.  The key thing that will affect all users is that the program will now be a natively <a href="http://en.wikipedia.org/wiki/64-bit#32-bit_vs_64-bit" target="_blank">64bit</a> application.  This will exclude users who still have 32bit systems, but allow the software to use more RAM, and therefore effectively do larger projects, on 64bit systems, which are pretty prevalent at this point.  From what I can tell, re-coding an entire application for 64bit is also good for cleaning up the code for existing features, and streamline performance and threading.  Avid&#8217;s primary competition: Adobe <a href="http://www.adobe.com/products/premiere.html" target="_blank">Premiere Pro</a>, saw a huge improvement in both performance and stability when the first <a href="http://www.adobe.com/products/premiere/faq.html#64bit-support" target="_blank">64bit version (CS5)</a> was released.  This has led to a huge increase in that application&#8217;s popularity, especially for larger projects.  The level of competition presented by that change may be a key factor in why we are now seeing so many major changes from Avid.<br />
<span id="more-314"></span><br />
The next most significant new feature, that will affect many users, especially new ones, is <a href="http://avid.custkb.com/avid/app/selfservice/search.jsp?DocId=422991" target="_blank">&#8220;Avid Open I/O&#8221;</a> which is Avid&#8217;s new approach to integrating hardware with Media Composer.  Avid now supports hardware I/O via products from <a href="http://www.aja.com/support/avid/index.php" target="_blank">AJA</a>, <a href="http://www.blackmagic-design.com/avid" target="_blank">Blackmagic</a>, <a href="http://www.matrox.com/video/en/solutions/avid/" target="_blank">Matrox</a> and others.  We have seen hints of this coming, with support for the Matrox <a href="http://www.bhphotovideo.com/c/product/820945-REG/Matrox_MXO2MINIMAX_T_MXO_2_MINI_MAX_w_LAPTOP.html/BI/6727/KBID/7302" target="_blank">MXO2-Mini </a>and AJA <a href="http://www.bhphotovideo.com/c/product/618185-REG/AJA_IO_EXPRESS_PCIE_Io_Express_Portable_Video.html/BI/6727/KBID/7302" target="_blank">ioExpress</a> in versions 5.0 and 5.5 respectively.  This change has two major benefits, it will allow most users access to professional hardware I/O solutions without paying for Avid&#8217;s overpriced <a href="http://www.bhphotovideo.com/c/product/568234-REG/Avid_7010_20460_01_Media_Composer_v3_5_Editing.html/BI/6727/KBID/7302" target="_self">hardware</a>, and nearly as important, it will allow edit systems to run multiple applications on the same system and hardware.  Add this to advances in project compatibility and interchange, and users will be able move their editing projects between Avid and <a href="http://www.tkqlhce.com/click-4107801-10549458" target="_top">Premiere Pro</a><img src="http://www.ftjcfx.com/image-4107801-10549458" border="0" alt="" width="1" height="1" /> (and <a href="http://www.bhphotovideo.com/c/product/639275-REG/Apple_MB642Z_A_Final_Cut_Studio_3.html/BI/6727/KBID/7302" target="_blank">FCP</a> on the Mac side) on the same systems, using the same video output hardware.</p>
<p>Avid also added a myriad of new features to enhance more advanced workflows, with better support for <a href="http://en.wikipedia.org/wiki/Stereoscopic" target="_blank">stereoscopic</a> content, more advanced <a href="http://en.wikipedia.org/wiki/Color_grading" target="_blank">color correction</a> tools, and <a href="http://en.wikipedia.org/wiki/Surround_sound" target="_self">surround sound </a>mixing options on the audio side.  They also have a 4:4:4 RGB version of the popular <a href="http://www.avid.com/US/industries/workflow/DNxHD-Codec" target="_blank">DNxHD</a> codec, and natively support ProRes files.  Their <a href="http://www.avid.com/US/products/Symphony/" target="_blank">Symphony</a> finishing toolset no longer requires Nitris DX hardware, but I have yet to find the pricing structure for that option.  It looks to be a solid feature set, and I am looking forward to <a href="http://apps.avid.com/media-composer-trial/" target="_blank">trying it out</a>.</p>

			<content:encoded><![CDATA[<p>Besides my <a href="http://www.adobe.com/products/creativesuite/" target="_blank">CS5</a> reviews, I haven&#8217;t posted much about new products or developments in a while.  There were a number of interesting releases at <a href="http://www.ibc.org/" target="_blank">IBC</a> last week, and a few from <a href="http://www.siggraph.org/" target="_blank">Siggraph</a> before that, that I hadn&#8217;t gotten around to yet.</p>
<p><a href="http://www.aja.com" target="_blank">AJA</a> released a variety of new products, most of them adding <a href="http://en.wikipedia.org/wiki/Stereoscopy" target="_blank">3D</a> related features to previously existing offerings.  The <a href="http://www.aja.com/products/kona/kona3g/index.php" target="_blank">Kona3G</a> is a revision to the existing <a href="http://www.bhphotovideo.com/c/product/417388-REG/AJA_KONA_3_Kona_3_12_10_Bit_HD_SD.html/BI/6727/KBID/7302" target="_blank">Kona3/Xena2Ke</a> that adds stereoscopic support through <a href="http://en.wikipedia.org/wiki/HDMI" target="_blank">HDMI 1.4</a> output and dual stream <a href="http://en.wikipedia.org/wiki/HD-SDI" target="_blank">SDI-3G</a> I/O, while also dropping in price about <a href="http://www.bhphotovideo.com/c/product/735417-REG/AJA_KONA_3G_KONA_3G_HD_SD_SDI.html/BI/6727/KBID/7302" target="_blank">30%</a>.  Their <a href="http://www.aja.com/news/index_article.php?id=124" target="_blank">Hi5-3D </a>replaces the <a href="http://www.aja.com/products/converters/converters-hd-hi53g.php" target="_blank">Hi5-3G</a> and adds HDMI 1.4 output as well as a variety of options for processing dual stream and muxed stereo inputs.  The <a href="http://www.aja.com/products/kipro/ki-pro-mini/ki-pro-mini-description.php" target="_blank">Ki Pro Mini </a>is a smaller version of the <a href="http://www.bhphotovideo.com/c/product/618146-REG/AJA_KI_PRO_R0_Ki_PRO_Portable_ProRes_File.html/BI/6727/KBID/7302" target="_blank">Ki Pro</a> that can now be mounted directly to camcorders, and record ProRes files directly to <a href="http://en.wikipedia.org/wiki/CompactFlash" target="_blank">CompactFlash</a> cards from HDMI or SDI inputs.<br />
<span id="more-182"></span><br />
<a href="http://blackmagic-design.com/" target="_blank">Blackmagic Design </a>had their own selection of new products to announce.  Their line of<a href="http://blackmagic-design.com/products/videohub/" target="_blank"> SDI routers </a>must have really taken off, because they are really scaling their offerings upwards, with new models that offer up to <a href="http://blackmagic-design.com/products/universalvideohub/" target="_blank">288 Channels</a> of input and output, and options for coaxial or fiber based connections.  I am just now upgrading to a 16&#215;16 3G <a href="http://www.bhphotovideo.com/c/product/686599-REG/Blackmagic_Design_VHUB_VM_Micro_Videohub.html/BI/6727/KBID/7302" target="_blank">Micro VideoHub</a>, but maybe someday.  Their other big news comes from their <a href="http://blackmagic-design.com/davinci/resolve/" target="_blank">DaVinci</a> line, with previously announced <a href="http://www.bhphotovideo.com/c/product/686594-REG/Blackmagic_Design_DV_RESSOFT_Davinci_Resolve_Software.html/BI/6727/KBID/7302" target="_blank">Resolve 7.0</a> for OSX finally being released.  It will be interesting to see what effect that new option has on the marketplace and the price of existing products.  My company will definitely be looking into setting up a Resolve system, and our primary colorist is very interested in the new capabilities it would give us.</p>
<p><a href="http://www.nvidia.com" target="_blank">NVidia</a> released their new line of <a href="http://www.nvidia.com/object/quadro-fermi-home.html" target="_blank">Fermi</a> based <a href="http://www.nvidia.com/page/quadrofx_family.html" target="_blank">Quadro</a> graphics cards at Siggraph.  The Quadro <a href="http://www.nvidia.com/object/product-quadro-4000-us.html" target="_blank">4000</a>, <a href="http://www.nvidia.com/object/product-quadro-5000-us.html" target="_blank">5000</a>, and <a href="http://www.nvidia.com/object/product-quadro-4000-us.html" target="_blank">6000</a> will be the successors to the current QuadroFX <a href="http://www.bhphotovideo.com/c/product/625332-REG/PNY_Technologies_VCQFX3800_PCIE_PB_nVIDIA_Quadro_FX_3800.html/BI/6727/KBID/7302" target="_blank">3800</a>, <a href="http://www.bhphotovideo.com/c/product/593449-REG/PNY_Technologies_VCQFX4800_PCIE_PB_nVIDIA_Quadro_FX_4800.html/BI/6727/KBID/7302" target="_blank">4800</a>, and <a href="http://www.bhphotovideo.com/c/product/593448-REG/PNY_Technologies_VCQFX5800_PCIE_PB_nVIDIA_Quadro_FX_5800.html/BI/6727/KBID/7302" target="_blank">5800</a>, with similar form factors and interfaces.  I have not had a chance to test them myself yet, but everything I hear has been positive.  <a href="http://www.adobe.com" target="_blank">Adobe</a> has announced that the Quadro <a href="http://www.bhphotovideo.com/c/product/726171-REG/PNY_Technologies_VCQ4000_PB_QUADRO_4000_PCIE_X16.html/BI/6727/KBID/7302" target="_blank">4000</a> and <a href="http://www.bhphotovideo.com/c/product/726169-REG/PNY_Technologies_VCQ5000_PB_QUADRO_5000_PCIE_X16.html/BI/6727/KBID/7302" target="_blank">5000</a> will be officially supported for <a href="http://en.wikipedia.org/wiki/CUDA" target="_blank">CUDA</a> acceleration by the Mercury engine in <a href="http://www.nvidia.com/object/adobe_PremiereproCS5.html" target="_blank">Premiere Pro CS5</a>.  This support came in the form of the Premiere Pro 5.0.2 update last week, which also adds the <a href="http://www.bhphotovideo.com/c/product/685479-REG/PNY_Technologies_VCGGTX470XPB_GTX_470_1280MB_GDDR5.html/BI/6727/KBID/7302" target="_blank">GeForce GTX 470 </a>as a fully supported GPU option.  More significantly from a technology standpoint, they added <a href="http://en.wikipedia.org/wiki/Color_depth" target="_blank">10bit</a> <a href="http://en.wikipedia.org/wiki/Displayport" target="_blank">Displayport</a> support for Quadro cards, and also support for <a href="http://www.red.com/store/775-0001" target="_blank">RedRocket</a> acceleration, RMD files and newer Red camera updates, as well as better support for <a href="http://en.wikipedia.org/wiki/Broadcast_Wave_Format" target="_blank">Broadcast Wave </a>and certain <a href="http://en.wikipedia.org/wiki/XDCAM#XDCAM_HD_.28XDCAM_HD420.2C_MPEG_HD420.29" target="_blank">XDCam-HD</a> files.  There is also a <a href="http://www.adobe.com/support/documentation/en/premierepro/cs5/adobe_premierepro_CS5_5_0_2_readme.pdf" target="_blank">6 page list </a>of smaller fixes in the new release, many of which fill significant holes in certain workflows.  I haven&#8217;t had much time recently to test out the new features, but getting 10bit color to my <a href="http://www.bhphotovideo.com/c/product/646265-REG/HP_Hewlett_Packard_GV546A8_ABA_DreamColor_LP2480zx_24_Professional.html/BI/6727/KBID/7302" target="_blank">Dreamcolor</a> is at the top of my list.</p>
<p style="text-align: left;"><a href="http://www.avid.com" target="_blank">Avid</a> <a href="http://www.avid.com/US/products/family/Media-Composer" target="_blank">Media Composer 5</a> was released three months ago, and they are now on the <a href="http://www.aja.com/products/kona/kona3g/index.php" target="_blank">5.0.3</a> revision.  I have had a chance to test it out at work, and while the ability to import any <a href="http://www.avid.com/static/resources/documents/solutions/AMA_Quicktime.pdf" target="_blank">Quicktime</a> via <a href="http://www.avid.com/US/products/Avid-Media-Access" target="_blank">AMA</a> can totally change the workflow for certain tasks, I wouldn&#8217;t use it as a primary way to edit large projects.  The performance and stability is not up to the same level as <a href="http://en.wikipedia.org/wiki/Material_Exchange_Format" target="_blank">MXF</a> based editing is.  You also need a very fast system for that to work.  Most of our Avids are HP XW8600s, while we have been dedicating our newer <a href="http://h10010.www1.hp.com/wwpc/us/en/sm/WF06a/12454-12454-296719-307907-4270224-3718645.html" target="_blank">Z800</a> systems to <a href="http://www.bhphotovideo.com/c/search?Ntt=CS5&amp;N=0&amp;BI=6727&amp;KBID=7302" target="_blank">CS5</a>, but AMA playback requires more computing power than <a href="http://en.wikipedia.org/wiki/DNxHD_codec" target="_blank">DNxHD</a> editing, which is to be expected.  We also found Version 5 to be less stabile and less responsive on our large feature length DNxHD project, even without AMA based media.  The fact that it fully supports <a href="http://en.wikipedia.org/wiki/Windows_7" target="_blank">Windows 7</a> will be the factor that motivates our facility wide upgrade in the near future.</p>
<p>I was also able to test <a href="http://www.bhphotovideo.com/c/product/706140-REG/Avid_7500_30124_01_Media_Composer_5_Production.html/BI/6727/KBID/7302" target="_blank">Media Composer 5</a> with my <a href="http://www.matrox.com/video/en/products/pc/mxo2_family/mxo2_mini/" target="_blank">Matrox</a> <a href="http://www.bhphotovideo.com/c/search?Ntt=mxo2+mini&amp;N=0&amp;BI=6727&amp;KBID=7302" target="_blank">MXO2-Mini</a>, for hardware HDMI out, and while it worked great at first, I once again saw a major hit in stability, with an escalating number of system crashes.  It is so close, but not quite there yet.  Hopefully we will see many of those issues worked out in intermediate dot releases, since most of these features are brand new.  Stay tuned, since I have a few other new toys that I will review in my next post.</p>
<p>FTC Disclosure: Many of the companies I refer to above have made their products available to me or my company in the past, but none of the new items discussed above were provided to me without independently purchasing them.</p>

			<content:encoded><![CDATA[<p>I have a strong personal preference towards using Windows PCs over Macs running OSX.  That said, Adobe&#8217;s release of an OSX of their CS3 suite of video products has recently brought me into more frequent contact with Apple&#8217;s products.  I currently have a MacPro tower in my office, primarily for testing purposes.  Until last week, the Mac version of Premiere Pro had no hardware I/O support, limiting its usefulness in professional environments.</p>
<p>Blackmagic has become the first company to support the Mac version of CS3 with their line of hardware products, with the version 6.6 release of their drivers on Oct 26.  I was aware of this at the time, but didn&#8217;t report it here until I had a chance to experiment with them myself.  I have installed a Multibridge Extreme in my MacPro and done some quick tests.  Everything seems to be in order, and most of the issues I encountered can be attributed with my lack of familiarity with the Apple way of doing things.<br />
<span id="more-19"></span><br />
The only real advantage I see Mac offering over the equivalent PC system, is that the Quicktime engine allows a greater variety of compression formats to be played in realtime through the hardware output. (For example DVCProHD)  I am hoping that this more open approach to compression support will allow Cineform compressed MOV files to be output in realtime sometime in the future, maybe even at 2K with the MultibridgePro.  I also hope to see this on PC, but the Mac Quicktime architecture currently seems one step closer to achieving this than the eventual PC solution.</p>
<p>I plan to do a more full fledged test of the HD-SDI I/O options in the near future.  So far, the only thing I have been unable to do, is get a realtime down-converted SD output of my HD timeline.  Does anyone know if this is supported, and if so, how to configure it?  I will need it to add pulldown, since most of my HD work is 23.976fps.  Since I only have an internal SATA array on the MacPro, I will not be able to push the Blackmagic hardware to its limits.  My three disks will be struggling to provide the data-rate required for 1080p 4:2:2, let alone 4:4:4 RGB or 2K.</p>
<p>UPDATE: I found the settings for downconverting, and it seems to automatically add pulldown for SD output, but I don&#8217;t see a way to add pulldown to HD output.  Unfortunately my system is currently doing a center cut to SD even when I have anamorpic or letterbox selected.  I have also been having many other playback issues, so it seems there are still a few things to be worked out.</p>
<p>One other benefit that the Blackmagic solutions provide, is that the same hardware can be used by PC applications in Windows.  This will be a significant advantage to those of you out there who are using Bootcamp to run Windows and OSX on a MacPro.  Currently Blackmagic offers the only hardware solution that publicly supports this dual environment compatibility.</p>

			<content:encoded><![CDATA[<p>I was never all that impressed with original Multibridge from <a title="Blackmagic" href="http://www.decklink.com" target="_blank">Blackmagic Design</a>.  It was not an I/O interface for your computer, it was just a Analog to SDI convertor, both ways.  When the <a title="Multibridge" href="http://www.decklink.com/products/multibridge/" target="_blank">Multibridge Extreme</a> was released, and with every major revision since then, computer I/O was added in a brilliant way.  Basically they embeding their <a title="Decklink" href="http://www.decklink.com/products/hd/">Decklink</a> electronics within the breakout box, and then devised a way to tap directly into the PCIe bus.  I don&#8217;t believe they created the original concept of External PCIe, but they were the first by a long shot to market a product utilizing the concept.  <a title="Caldigit" href="http://www.caldigit.com/HDPro.asp" target="_blank">Caldigit</a> and <a title="Ciprico" href="http://www.ciprico.com/Products/MediaVault.cfm" target="_blank">Ciprico</a>, among others, have recently developed drive arrays with an external RAID controller that uses the same basic connection.<br />
<span id="more-5"></span><br />
Another major feature that the Multibridge was the first to offer, was DVI output for monitoring on an LCD in full screen independent of the graphics card.  It was also the first simple solution for monitoring 2K at fullscreen, using the DVI port to drive a 2560&#215;1600 pixel LCD.  This has been replaced by HDMI in the newest revisions, removing integrated 2K monitoring support, but that is now offered through the <a title="HD Link Pro" href="http://www.decklink.com/products/hdlink/" target="_blank">HDLink Pro</a>.  The most recent version, the <a href="http://www.bhphotovideo.com/c/product/542190-REG/Blackmagic_Design_MULTIBRPRO2.html/BI/6727/KBID/7302" target="_blank">Multibridge Pro</a>, can capture or convert to and from HDMI, SDI, and Analog formats.  Their newest feature is support for 3Gb/s SDI, allowing HD 4444 and 2K 444 over a single cable in realtime. (Which allows 2K preview on an 30&#8243; LCD though the <a href="http://www.bhphotovideo.com/c/product/620822-REG/Blackmagic_Design_HDL_PRODVI_HDLink_Pro_DVI_Digital_HD.html/6727/KBID/7302" target="_blank">HDLink Pro</a>, which is a separate item)</p>
<p>On the PC side, they support three basic editing modes, well really two and a half.  Uncompressed is their primary format, 8 or 10bit, 422 or 444, and now 2K.  They recently added a compressed MotionJPEG codec, but they have not unlocked all of the options to vary the quality yet.  This allows the realtime capture and playback of compressed files through their I/O.  Their MotionJPEG codec is 8bit 422, and from my use, I would class it as a great codec for full rez and frame rate offline editing, if you are finishing to HD or Film.  For Web encodes or SD, it is probably fine for online work, unless you need 10bit for Digibeta.  The last option is a Capture only one, into the <a href="http://www.cineform.com" target="_blank">Cineform</a> codec.  I know for a fact that this works over HDMI on the Intensity card, but I have heard that all of the Blackmagic products are supported.  Blackmagic products are the only way to capture RGB over dual link SDI in realtime to the new Cineform 444 codec, and possibly even to Cineform2K.</p>
<p>There are a few disadvantages I am aware of.  Low realtime effects or rendering support in their hardware or editing modes.  They don&#8217;t support many compression schemes, MotionJPEG being somewhat limited.  The big issue in using it with Cineform is that it seems that realtime monitoring is not available from Cineform RT projects in Premiere.  Lastly, <a href="http://www.bhphotovideo.com/c/search?Ntt=Blackmagic&amp;N=0&amp;BI=6727&amp;KBID=7302" target="_blank">Blackmagic</a> products are known for their reasonable prices, but not their long lifespans.</p>
