When using after affects how can I edit my iclone movie and give it a better quality of graphics?
Also I have after affects but would I need sony Vegas pro to edit the quality of the graphics or will after affects do the job.

I haven't used AE in a long time but you should be able to import iClone footage directly into AE.

For best quality you would export uncompressed from iClone. My preferred method is using PNG image sequences. This will give you compression without quality loss. You would export at the highest resolution. I think that is currently restricted to 3000 pixels for the longest dimension, so you could do something like 2560 x 1440.

When I used AE I was impressed how well it resized video. It was very slow (but that was a long time ago) but the quality was good. You can render from AE in your required format.

If you want to use Vegas to edit your movie first and then process it in AE, you could still keep using image sequences until the very end. I believe Vegas renders into image sequences.

We have some actual AE users among the members, so they may have some ideas too.

Use AE for short clips where you need to have some effects. Use Premier or Vegas for final movie editing.

Use Image sequence from Iclone in AE. Add all effects you want. Then edit in Premier. You can directly link your AE project in Premier and all subsequent changes will reflect. That way, you don't have to render out from AE. You can take the final output from Premier after mixing sound etc.

If you have AE then you should also have Adobe Media Encoder.
Render directly to this rather than AE's built in module since it's somewhat sketchy.

Media Encoder will give you any number of output options and then some.

When you say, 'better quality of graphics' though, this is somewhat subjective.
Don't imagine that after effects is magically going to transform your iclone animation into a pixar masterpiece (well, not at this point in time anyway).

Thanks. Though I've been using this for 3 years, I plan on getting better making iclone videos and games I do have a lot to learn.

anyways this helped out a lot
