Question: Best way to export HD footage to 'KEY' in After Effects (AVC-HD)

Apr 12, 2013 8:00 AM

So I have 15 mins of footage in premiere that i'm going to edit down to about 2 mins. This will then need to be keyed out (green screen) so I figure I need to bring it all into AE and use the KeyLight plugin. Should I export the whole project or use the  'replace with after effect composition' by 'right-clicking' on each clip?

 

If i export the project (using adobe media encoder) what is a good format to export to because AVCHD is not an option.

    That's what I would do.

    Something lossless like:

     

    Lagarith Lossless Video Codec

    or

    Ut Video Codec Suite

    The Replace with... option is a good one.  But if there are a lot of clips from that one 15 minute segment, it might just be easier to do the keying first by bringing the original clip into After Effects, key the entire thing, and export a lossless Intermediate for editing.  You'll have to decide which is easier for you.

    key the entire thing, and export a lossless Intermediate for editing.

    This is also a good approach...

     

    But if your background images might change in editing,

    be sure to export an intermediate with alpha channel included.

    That's why you have to decide which is the better method.  You know your machine and it's abilities far better then we.

    My five pennies: keep in mind that you can replace a group of clips with dynamically linked comp, not just one clip.
