[FFmpeg-user] Slight blur on converted video

[chronek]

If  "ffmpeg -i in.mp4 -acodec pcm_s16le -sws_flags 
full_chroma_inp+full_chroma_int+accurate_rnd+bitexact -sws_dither none 
-vcodec prores_ks -profile:v 1 -copytb -1 out.mov" not work as should 
then there are posibilities (1) you are using old ffmpeg (2) there is 
bug in ffmpeg decoder what deblock h264 when it shoud not (3) AME is 
encoding to different settings than prores_ks profile:v 1 (4) theres 
problem with timestamps and ffmpeg trying sanitize it by blending frames 
to keep framerate


please provide a small part of your source video for testing
