I thought a thread like this might be of some general\ninterest. Basically I'll try to provide a description of my\nprogress and lessons learned along the way.\n\nA little on why I'm moving my video to AVC/H264,\n(more detail latter if asked for).\n\nThe main attraction, for me, was that this is a format\nthat can archive my current standard definition video\nand can also handle HD material well. The same can be\nsaid for MPEG2, but AVC allows for much smaller files,\nat a given quality of video.\n\nThe various Profiles (Baseline, Main, and High - plus a\nnumber of offshoots) and Levels, as well as features that\ncan be implemented (or not) within the format, like GME,\nCABAC, and Qtr Pixel; make it useful in almost any\nenvironment. The encoding can be tailored to many\ndevices and uses.\n\nAVC also allows for/supports, playback optimizations\nto form a bigger part of the overall quality of the displayed\nvideo. This can mean a greater demand on the playback\ndevice, when all the goodies and/or HD is involved. You\nwill want a fairly up to date system, to take advantage of\nall the playback features. (Both ATI and Nivida have some\nhardware acceleration for AVC, and are working on more.)\nThese playback options allow AVC to out perform XviD or\nDivX at the same compression setting.\n\nTiming is another factor, the right tools are either out of beta\nor just about there. The new TMPGEnc 4.0 XPress encoder\ndoes a great job implementing Main Concept's AVC encoder.\nElecard (a branch of Main Concept, now) has it's codec pack\nand a "Mobile Converter" program for AVC. Cyberlink's\nPowerEncoder AVC, was a major disappointment, but shows\nthat the industry is moving in the direction of AVC/H264. The\nfree x264 has provided a good and stable platform for those of\nus who wanted to gain experience with the format. (It's still quite\ngood, and plays well with VLC but it's not keeping up with the\nlatest offerings.) The CoreAVC playback codec is a major\naddition to the field, and significantly reduces the demand on\nsystem resources during playback. (, for the Pro version\nand includes the Haali Video Renderer and the CoreAAC\ncodec)\n\nThere is also the fact that AVC/H264 was selected for both\nof the HD DVD formats. There should be considerable\nsupport on an ongoing basis for this format.\n\nThe bottom line for me is that with AVC/H264 I can take\nmy 1/2 D1 MPEG2 and make full D1 MPEG4, at nearly\nhalf the file size, that plays great on my HD projector into a\n100 inch screen. (and looks even better on my computer\nmonitor)\n\nSo that's why I'm doing it; my next post will go more into\nthe process and tools that are working for me.\n\nLuck;\nKen\n\nP.S. Let me know if there is any interest in my continuing\nwith this.
