Is this transcoding the video?

I have an application used in government and subject to regulation that prevents transcoding or altering the video quality in any way.

I'm attempting to utilize FFmpeg to change a video into an MP4 by copying the raw streams to a new container.

This is the command being used:

ffmpeg.exe -y -i INPUT.ASF -c:av copy OUTPUT.MP4

Notice the -c:av copy. The FFmpeg documentation says, “a special value copy (output only) to indicate that the stream is not to be re-encoded.“

Visually the videos before and after appear to be identical quality with no pixelation on the ships.

Is this altering the video quality or could this be considered transcoding?
