Hi Team,

I am currently working with ffmpeg 4.2.2 for video transcoding. My objective is to transcode a particular .mov file to .mp4 file and compress to a significant amount.
I am using the following command:-

ffmpeg -i Input0.mov -y -fpre ./preset/mp4_Projector.ffpreset -astrict -2 -vsync vfr -acodec copy -vcodec copy -s 1280x720 Output0.mp4

The description of preset file that has been used is as follows:-


But the output .mp4 file is not getting compressed. For example:- if the size of .mov file is of 563.2 MB, then the size of the output .mp4 file is becoming 560.1 MB

My further development work is stuck due to this. So, requesting you to kindly assist in this and help me with some solutions.

Thanks & Regards

Rakesh Chakraborty
