Can you give us the full specs. of that Clip (the Lagarith CODEC w/ Alpha Channel)?
Can you tell us about your Sequence Preset?
Sequence is DV NTSC Standard 48kHz
Clip is AVI Container 720 x 480 48000 Hz Stereo, Codec LAGS (Lagarith Lossless)
The clips plays fine, it just will not export the timeline when it hits this section. I have replaced all the clips with a different codec and it does the same thing.
I have placed all the clips in a separate sequence created from the clips, same thing.
Obviously, you are using the Alpha Channel for some Transparency. Are there any other Effects applied to that problem Clip?
If you could post a screen-cap, showing that Clip Selected (and probably the Effects Control Panel also), plus the underlying Clips on the Timeline, perhaps someone can see an issue there.
You do have the 64-bit version of Lagarith installed, don't you?
There are no effects on the clip at all. I do have the latest 64 bit codec installed.
I was able to get the programs output, by taking the clips, making a comp in after effects and rendering out a new uncompressed AVI with Alpha - I turned off include project link and XMP metadata (don't know if this helped), but it worked fine when I replaced the clips in the project.
