Background not showing
I have rendered a 150 frame scene from Lightwave 9.3. It has a spinning logo and a background image. During the render in LW I can see the background. When I put the footage into Premiere PRO 1.5.1 I can’t see the background image. I have viewed the frames in Photoshop and the background image is there. I am also going to post this message in LW and Photoshop.

The image of the BG you are seeing is probably in the Alpha Channel of the file you’ve rendered from LW. I’ve worked with LW alot and know it can imbed BG info in the A-Channel. Try telling the clip to ignore the Alpha channel. See if that helps.
(Right click the clip in the Project panel>Interpret Footage>Ignore Alpha)

I did as suggested and it didn’t work. No background.

I take it back. I showed the first frame only with the background.

I changed the format to Animation.avi and ignored the alpha channel in interpret footage. Everything works.

Great to hear you got it working. 🙂
The Alpha channel can be a cheeky little bugger. Opening in AE and playing with the alpha settings there usually lets me know exactly what’s happening.

It worked because I chose “animation” and not “RGB” I would much rather use “RGB.”

Is there any reason you’d prefer to render out in RGB? It’s extemely common for animation to work with image sequences of either TGA, TIF, or PNG. These codecs are lossless and can hold an alpha channel in 32bit mode. A major benefit of image sequences is that if you stop rendering for whatever reason (blackout) you can pick up where you left off. Whereas an avi or mov file is cut short and you need to edit them together. (A blackout would lose the whole mov or avi – no time wrap the rendered frames).

I changed to 24bit in RGB and it worked. When exporting RGB from LW, it is always done in frames. If something crashes, I can always go back and start at the next frame to continue.
