Thanks, I tried this suggestion $ ffmpeg -i %INFILE% -c copy -movflags +faststart %OUTFILE% and it resulted in a 2-pass operation, the first took a bit over 1 minute and then there was an operation wehere the "moov atom" is moved to the front of the file, took about the same time. So in all about 2+ minutes rather than 10, a good improvement. But now I have an mp4 file that is about 1.3 GB whereas they are about 450 MB when I also cut down the size. Which takes about 10-11 minutes. I have changed my script command which scales down the size so instead of going to 480p I am now going to 360p, which is an even number operation regarding pixels (1/2 in both directions), should improve processing. With this the size conversion from 1280x720 to 640x360 takes 6-8 minutes rather than 10-12 before. I have to make up my mind what is the best compromize here. -- Bo Berglund Developer in Sweden _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
