Custom transcode profile ?

[TheDreadPirate]

I'm assuming you are talking about the "Quality" selector. That doesn't actually force the stream to be that bit rate. It only sets the maximum allowed bit rate. If the video happens to be lower than, in your example, 10Mbps than the video will direct play (assuming it is compatible with the client).

The resolution in the quality selector also doesn't really change anything.

When Jellyfin is converting from codec to another during transcoding, it will apply some loose math to account for changes in encoding efficiency. It will take the original video bit rate and increase or decrease the bit rate appropriately.
