It is important to stick to some input source variant or take a look at different options (and tweak guide accordingly).įrom what I know, avi/lossless RGB uses vfw direct conversion and mp4/h264 uses vegas-integrated mainconcept avc decoder.Īnd it can become BT.601/BT.709 mess for avi/h264 sources (depends on OS, installed filters, capture software etc.). Vegas uses 8-bit or 32-bit sRGB for internal processing (studio levels or computer levels), so every YUV input is converted by Vegas and/or vfw filters. Unfortunately, Vegas can handle different input sources differently. Are you talking about the video colors? I've found that the colors with this method are much more true than any other I've tried. That is the only time I used RGB lossless. For testing purposes only I used RGB lossless, so that I could see specifically the difference in encoding techniques. However there are visible artifacts in those recording without any re-encoding. I actually use lossy h264 AMD APP hardware accelerated encoding with Action! and Bandicam for my gameplay captures. Sony AVCMVC does not have VBRCBR options. your excessive render bit rate could be messing with youtube. your excessive source footage bit rate could be messing with Vegas. To achieve this one must use the Debugmode Frameserver, MeGUI, AviSynth, and the Nero AAC codec with the following command line: -keyint 30 -bframes 2 -b-adapt 0 -b-pyramid none -weightp 0 -me umh -direct none -no-fast-pskip -scenecut 0Īnyway, the tutorial is in video format and you may find it here if interested:Īdditionally I've made comparisons in quality between this method and others so that you may verify that this, indeed, looks better: try recording at 21 Mbps, and render out of Vegas at 21 Mbps using Sony AVCMVC codec, and choosing one ot its AVCHD templates. Here is an example of difference in quality between my settings and the default Sony Vegas renderer (my settings are hej): The premise is that by rendering a video specifically in accordance with the encoding settings suggested by YouTube you get the best quality possible.
I do not post much here but I have been a member for some time and have used the information in this forum to create this guide for achieving the best quality possible on YouTube.
