Compositing the Maya scene files

[ankuragarwal]

I am making a film for the first time using Maya, and so I wanted to ask something about the compositing softwares.
1] Should I do my compositing in Adobe Premiere or in Combustion ; what is the difference between the two ?

2]I also wanted to ask that can I open up a project done in Adobe Premiere in Combustion also or vice versa?

3]And one more question, please. Say, I have rendered my film in Maya with targa as the output format for each of the frame images, and then I import them into Premiere or Combustion and finally produce an avi video file. Now, if suppose I want to introduce some effects in between using say, Adobe After Effects, then should I :-

a)simply work on the avi video file. Is that possible ?
b)import the whole project in After Effects and introduce the effects.
or c)import all of the targa scene files from the Maya's renderScenes directory and again resequence/edit them and then finally introduce the effects.

I think (a) might not be possible.
Thanks in advance, please answer all of my questions.

1) Combustion. Premiere is editing software. You can do some basic compositing with it though.

2) I think not.

3) Despite it's name After Effects in not only "effects" software. It's a compositing software - similar to Combustion ( although it lacks some power ). You can manipulate your footage in any way - it depends on the nature of the "effect". But normaly you want to do all of the "effects" on uncompresed targas, not on compressed avis - bacause once the footage goes to avi it's quality is diminished considerably.
You should produce an avi when everyitng else is done ( compositing, effects, editing ) - and it should be used only for previewing purposes.
