Encoder Options - AVI Format
on Mar 25, 2010 at 3:57:32 pm

This is sort of a followup to a post I made last week, but new thread since the question is different.


Output request is and AVI encoded with Matrox MPEG-2 I-Frame only codec or uncompressed AVI. From what I can tell, the only requirement is that it must be an AVI, since it's going to be loaded into a Click Effects system for display on a stadium's electronic billboard.

Matrox codecs are hardware locked, so I'm looking into exporting the AVI with MPEG Streamclip on my Mac. Is there a specific encoder I should favor or stray away from? Looking at Wikipedia, it appears the accepted encoders for AVI are MJPEG · Motion JPEG 2000 · MPEG-1 · MPEG-2 (Part 2) · MPEG-4 (Part 2/ASP · Part 10/AVC) · HVC.

If they need i-frame only or uncompressed it's for a reason and as such given them a LongGOP file (the other formats you list are all LongGOP except JPEG2000) is likely to be unacceptable.

It might be worth contacting Click Effects to see what they do support?

Now that I look again on the Click Effects site, it looks like an Uncompressed AVI is preferrred, and AVI is the only accepted format.

What I didn't realize is that AE on PC allows you to output an AVI ("Video for Windows"), while it's not even an option for AE on a Mac. Since this project relies heavily on AE plugins, I'll render out a QT Animation from AE on the Mac and use AE on the PC to transcode to Uncompressed AVI.

You can export Uncompressed AVI out of Quicktime Pro 7 on a Mac.

Nice. I saw that yesterday, but thought it was the equivalent of selecting "None" in FCP when outputting with QT conversion.

Good to know. Thanks Daniel.

'None' in this case means no compression, despite 'CODEC' meaning COmpression DEcompression, a 'None CODEC' is an uncompressed CODEC. Remember both AVI and Quicktime are just wrappers for CODECs.

Right.


It makes sense that "None" is uncompressed, I was confusing it with the "Video" codec in FCP.
