AVI on MAC
Our production house uses two main formats to export: MOV and AVI. The PCs all do AVI, but so do half the MACs. The AVIs from the MACs seem to be stretched out on the right hand side. You can really tell when you bring them into FCP, or Premiere again. Both are set for DV NTSC and export at 720*480. The MOVs are fine, but any of the MAC AVIs are stretched. What could be causing this?

FCP is not meant for AVIs. You need a program that re-wraps the DV stream from AVI to MOV. Any regular conversion is no good as it will re-compress it and cause severe quality loss.
This is what I used to use:

But the AVIs that are exported from Premiere look fine. Its the ones exported from FCP that looked stretched when played back in any editing software. Seeing as that AVI is a standard, shouldn’t FCP export AVIs the same way as Premiere?

And what about the anamorphic flag or pixel dimension flag? You sometimes have to tell FCP how to interpret an imported video.

The AVIs are 4:3 in a 4:3 sequence. I dont see a pixel dimension flag to check in the format tab. And when it stretches the MAC AVIs, it stretches them during playback and export, and they go outside the safety lines off screen.

The flags can be changed in the FCP browser. Change the pixel aspect to DV instead of square. Other than that, I don’t have an answer for you. FCP is absolutely not meant to use AVI files.

Well, it seems that after export, it looks ok. But if FCP were not meant to use AVIs then why do they?
