QT Animation at 100% and 24 bit looks horrible and jagged
Premiere CS4. I’ve never had this issue before and there has been no change in my software. I’m assuming quicktime got updated or something like that. Tried restarting programs and PC to no avail.
My video is 1280×720 (1.0), 29.976 fps, progressive scan, exported with the Animation codec at 100% quality.
I’ve tried changing the bit depth to 8, 16, 24 and 32, and selecting and deselecting “Render at Maximum Depth” (on 8-bit the exported video is black, by the way). But at maximum it still looks like that.
According to VLC, this are the codec details:
Codec: Apple Quicktime RLE Video (rle)
Language: English
Resolution: 1280×720
Frame rate: 19.365250 (<- notice this!)
Decoded Format: 24 bits RGBNoticed the framerate? On the codec setting at export I made sure it was the proper number, but VLC still gives that off. When I exported at 8 bit the fps was around 6 according to VLC.
Quicktime player also shows messed up video, so its not the player.
Can anyone advise?

Try a different codec

I don’t think changing the export setting for bit depth will matter because Animation is 8-bit per channel. Also, the 19 fps reading could be the result of dropped frames during playback.
Questions:
- What codec is the source footage, or was the gradient generated in Premiere?
- Are you using a Mac or PC?
- What version of QuickTime?
- Did you use CPU or GPU encoding?
- If you import the Animation file to Premiere and view frame by frame, are there any repeated or dropped frames?
- What will be the final delivery codec for the compressed video?
As Chris suggested, try exporting a short test clip using other codecs. Compare 8-bit vs 10-bit, RGB vs YCC (YUV), QuickTime vs AVI. Examples include AVI 10-bit YUV, AVI None, QT JPG2000 or PNG, or QT ProRes 4444 (if available).
