lossless copy problem
I'm trying to run a .TS file through ffmpeg in order to resync the audio. I am using the following command line in an attempt to get a lossless copy while still resyncing (won't resync if I just say -c:v copy):
Code:
ffmpeg64 -v verbose -y -i "S:\VFolder\A.ts" -c:v mpeg2video -q:vscale 0 -c:a ac3 -ab 384k -ac 6 -async 48000 "S:\VFolder\A_FIX.ts" Media Player Classic plays the original file fine with the deinterlacer providing good quality. However, the fixed TS file plays, but since it is read as progressive, the deinterlacer doesn't work. How can the output file have a lower bitrate and be considered progressive if I used a constant quantizer of 0 and didn't use -deinterlace or -filter:v yadif? How can I make sure the scan type remains the same and the quality is lossless? I don't care how large the fixed file is. Last edited by agni451; 25th November 2012 at 13:46. |
