.avi a little bit heavy

[toto6976]

hi,
currently I use the command "scrcpy --record=file1.mp4". The files are a bit heavy. Is there a way to have smaller files?

Encoding is performed by the device. The bit rate is by default requested to 8Mbps (but the encoder decides depending on frame complexity).

Since it's live (hardware) encoding, it's not the most efficient.

For a better quality per size ratio, I suggest to record with a high quality (scrcpy --record=file.mp4 -b16M), then reencode with ffmpeg more slowly. For example:

In H264:

ffmpeg -i file.mp4 -c:v libx264 -qp 25 output.mp4

In AV1:

ffmpeg -i file.mp4 -c:v libsvtav1 -preset 7 -crf 35 -c:a copy output.mp4
