Hi I was using -vcodec libx264 with -sameq

and found the files were doubling in size

so tried -vcodec copy

and all fine and so quick to convert!

is there any reason why I shouldn't use -vcodec copy?

[richie bee] "is there any reason why I shouldn't use -vcodec copy?"

Depends on what you are doing.

If you are just repacking the stream into a different container or splitting the audio from the video, -vcodec copy is the right choice as it does exactly what you would expect, copy the stream without re-encoding.

If you are changing bitrate, size, aspect or applying filters, this is not a good choice.
