Artifacts After Rendering
Hello,
I’m having an issue with final cut pro 7. Every clip in my timeline that I’ve had to render (as in, where I’ve added a title, or where I’ve punched into a shot) results in significant blocking artifacts. It’s visible in the canvas and visible in the exported video. Literally when the title comes up it becomes blocky, and then when the title goes down, it’s back to normal. If I put a clip back to its original 100%, or remove a zoom in, it’s perfectly fine. I’m using H.264 files taken from 4k red files.
Appreciate the help, thanks.

FCP doesn’t work with H.264 files. Gotta use editing codecs..ProRes 422, HQ. If you want a low data rate workflow, then use Resolve or Red Rocket to make ProRes Proxy files.

I’m confused by what you mean, as I was able to edit the H264 in the timeline and export it. It’s only on the rendered shots that there’s any issue. Otherwise it’s fine.

FCP 7 and H.264 are unpredictable. It isn’t an editing codec, and FCP wasn’t designed to work with it. It APPEARS to work, and might work for a bit, but then major issues can arise. Most are sync related, but artifacting is nothing new. The fact that you were able to do this up until now is luck. H.264 is just not good for editing. Other apps say they work with it, and can do better than FCP…but still they suffer issues like lagging on playback, stuttery playback, sync issues.

ADAM…listen to the experts…FCP7 = All flavors of Prores.

i agree with the others: H264 is unpredictable in FCP7 and using it is asking for trouble.
however you should also check your sequence’s render settings.
have they been set to 50% Quality or less?nick

Thanks for the help everyone. I changed to pro res and all is working smoothly now.
