Ensuring all-YUV handling+export in Premiere Pro 1.5

[sharper]

I need to trim/join a lot of YUY2-spaced uncompressed AVI files. In my Premiere Pro 1.5 I start a project with AVI No Compression as setting, and import the YUY2. Problem is, when exporting an uncompressed AVI, it's RGB24! (according to virtualdub)

Since Premiere Pro is all YUV, this shouldn't be a problem ... how do I stay YUV all the way? Should I use some other YUV-specific codec when exporting, am I sure there hasn't been a YUV-RGB-YUV conversion then?

Interesting.

If your project setting is YUY2 and your source is YUY2, then you just trim edit and export YUY2 there should be no RGB conversion.

RGB conversion may happen during effects or filtering but that should get reconverted to YUY2 for export.

The old Premiere would have converted any input to RGB24.

Premiere Pro works in YUV if you use settings that support YUV, like DV-AVI, Huffyuv, Lagarith and so on. By using Uncompressed AVI for project settings, I'm guessing you are inadvertantly converting to RGB. I would use Huffyuv or Lagarith for losseless compression, they both support YUV.

You can always use Debugmode Framserver with YUY2 settings. That should guarantee that it remains YUY2.


Opening that frameserved avi in Virtualdub gives the following error:


That proves it remains YUY2.

Lagarith was the solution. There is a "Report Original Colorspace" switch that "prevents Premiere from losing the codec".

Also, capturing uncompressed video in Lagarith YUY2 made the bitrate only twice that of DV AVI. Stunning stuff, highly recommended folks.
