FCP 5 “Codec Error” when Rendering
After some hair pulling I was able to set-up a Sequence that contained 2 different .mov files all of which shared the same settings including the sequence itself.
Custom 914×686, Square Pixel Aspect Ratio, Field Dominance = None, Editing Timebase 30, Compressor = H264, Quality = 100% and no Audio.
The 2 .mov files are screen cap videos, one from Camtasia (PC) and one from ScreenFlow (Mac).
When I brought the 2 files into the sequence, no rendering was required and everything worked. The second I added Motion (e.g. Scaling one of the clips from 100% to 50%) the dreaded red line came up and I had to render.
When I tried to render I received a message “Codec Error”.
Anybody have an idea of why this is happening.
Many many thanks for any help.

Same problem. i just added the effects in the customized sequence, then i copy the whole edit to a DV NTSC sequence and rendered and worked.
still i’d like to know what’s the problem with the h264 sequence. -
It is probably a bit late now but I have seen this happen to many other people and it has just happened to me today but thankfully is now sorted. I was trying to export from my timeline as I have done many times before only this time I got the Codec Error. I tried trashing the preference files and then also noticed that for some reason there was a marked inpoint right at the end of my sequence so I deleted that and everything is working again. So either it was the preference files or the marked in point. Hope that helps in some way.

I got the same message after changing the speed of a clip. I copied the assets into a new timeline and was able to render without a problem.
