As I process broadcast files, most of them have ten seconds of idents at the start and 5 seconds of hold on the end.

It would be great it there was a setting under 'effects' to tell media encoder to automatically remove x amount of frames from the start and end of the clip. You can adjust this to suite so you are left with only the actual content.

An additional feature would be to ask media encoder to add a hold onto the end of a clip. For instance broadcast files have 5 seconds hold, but other content delivery companies want ten seconds. So it would be helpful to tell media encoder to add x amount of frames as a hold on the end.

Root6 Content Agent Encoder Software and Telestream Vantage have this feature.
