Welcome to the forum.
I am not familiar with that particular error message, but with "Failure to Return Frame," or similar syntax, it is caused by there being a gap in the Video Stream. That might be a tiny, one-Frame gap, or a larger one.
I would check the Timeline very carefully (zooming in horizontally to the max), and especially about the point, that the Transcode is failing, but remember, that might just be the first problem, and there could be more lurking down the Timeline.
If you need a gap between Clips in the Timeline, create some synthetic Black Video (New Icon in the Project Panel) and fit that into the gap.
Another "trick" is to create Transparent Video, place it on a higher Video Track, and extend that to "cover" all gaps in the lower Video Tracks. Personally, I like Black Video.
Good luck, and hope that it is just a gap in your Video.
Thanks for the prompt reply Bill. I have done what you said and added black video in the gaps between the titles (which never caused problems before, but may be now) and upon exporting I go the same error. After reading your article I saw that maybe I should add black video to the end, which is what I will try right now and get back to you on. All of my audio is in the .wav format, so shouldn't have any mp3 issues to deal with.
No, the PCM/WAV material should not be an issue, and that you were able to Transcode the Audio, seems to indicate that it is not a problem.
Good luck, and when you track things down, please post the solution. Also, another user might have experience with your particular error message. I am just not familiar with that module.
Thanks! I'll keep you posted. So far no luck with filling the gaps. The error, I noticed, does pop up sometimes when I'm not rendering. I am trying to track down all the frames it is indicating (which change everytime I get the error while rendering, which so far happens everytime I render) and clipping them out. Will keep updating this.
I have literally tried everything and am at a complete loss. I filled the timeline gaps with black video, nothing. So then I put a transparent video above the whole project, still get render errors about failed frames. Each time I render it's a different frame, even if I don't remove the frame it specified before. Beginning to think there is some corruption in the CS3 program files, but don't know how to track it down and with Adobe support telling me the solution is simply to buy the new version, not sure I can do a 'repair' on the CS3 program.
Any thoughts or additional help would be greatly appreciated.
As far as I know there have been no software or hardware changes since the last successful render a month ago.
