Cutting up large (filesize) clip into smaller clips

Thanks for the replies.

I get what you mean about Premiere Pro, I just prefer the way After Effects works, it seems more intuitive than PP. I will persevere and see how I get on, I suspect the slow processing maybe down to my old Mac!

I too recommend using Premiere. You can get your clip in to the source monitor, set in and out points and then go to clip/make subclip.

Then export those clips through Media Encoder. If you need more info you may want to ask in the Premiere forum

Four words:

Use Adobe Premiere Pro.

I'm not following your workflow.

Are you duplicating clips in the Project Panel? Are you duplicating clips in the timeline? Are you trying to edit a long interview in After Effects? Are you duplicating clips on the hard drive?

After Effects and Premiere Pro are nondestructive. There is no need to have a duplicate of your footage unless you require a backup.

What are you doing to the footage in After Effects? Struggling with a render may be completely normal if you are trying to render a half hour interview in AE. It's not an NLE, it is a visual effects app specifically designed to produce visual effects and motion graphics shots, not movies, but shots, that you cannot produce in a nonlinear editor.
