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:-

vcodec=libx264
vprofile=main
level=30
b:v=800000
bufsize=800000

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
