When I drop an mts file in to the time line it immediately needs rendering. On previous versions this was not required
unless I addded an effect or somethng. The file is mts recoreded in
AVCHD in HD. Could this be the problem? It is also very jerky in the programme monitor on playback unless it is rendered.
That is the name of the game with that material.
Harm, Is the answer then to record in non HD or 720 x ???? then?
AVCHD requires quite some muscle from your PC. If your PC is not fast enough you can consider getting a faster PC or converting to a format that is easier to edit.
