Oxygen decompressor6/19/2023 ![]() ![]() Using TMPGEnc you have to add the line " ConvertToRGB24" (with proper "interlaced" option) to your script, and for CCE SP you need to add the line " ConvertToYUY2" to your script, since Windows has no internal YV12 compressor. What will be the main advantages of processing in YV12? You can also install some YV12 decompressor (codec) which will decompress the YV12-AVI for you when loading the avi in TMPGEnc or CCE SP. That depends entirely on the external plugins whether they will have YV12 support or not. Speed increases like 25-35 percent are expected. Of course there will only be a large speed increase if both your source and target are in YV12, for example in DVD to DivX/Xvid conversions. The colour information doesn't get interpolated (so often) and thus stays more realistic. ![]() MPEG-2 encoders such as CCE, Procoder and TMPGEnc can't handle YV12 input directly. CCE and Procoder needs YUY2, and TMPGEnc RGB24. If you are making a progressive clip there is another advantage.All internal filtering in AviSynth will be faster though (less data to filter, better structure to filter, and a very fast conversion from YV12 to YUY2), and you will definitely be able to tell the difference between v2.06 and v2.5.This only means that the last line of AviSynth must be a ConvertToYUY2 (for CCE/Procoder, or ConvertToRGB24 for TMPGEnc) call, and that you will not be able to take full advantage of YV12 colorspace. Putting off the YV12->YUY2 conversion until the end of the script allows you to first IVTC or Deinterlace to create progressive frames. How do I use VirtualDub/VirtualDubMod such that there are no unnecessary color conversions? But the YV12 to YUY2 conversion for progressive frames maintains more chroma detail than it does for interlaced or field-based frames. Just load your avs file in VirtualDub/VirtualdubMod and set the video on "Fast recompress".
