White Flicker h.264 DSLR1080p Timeline

Sorry, just saw the H.264 in the title… but would still like to know the compression settings. Thanks.

Thanks Ivan. The footage came straight from the 60D (h.264 Linear PCM, uncompressed audio 16bit 48kh in quicktime wrapper). About a 45Mbit/s.

Not sure if that’s what you were looking for. As it turns out it doesn’t export in the render (both 422 HQ and Vimeo HD mp4) as far as I’ve noticed but it’s a bit irritating while editing.

I thought there might be an All-I setting on the camera. I just looked through the user guide and did not see any, so please disregard.

Not sure if we are referring to the same thing. When previewing compressed footage it might be necessary to render the sequence so Premiere doesn’t need to decode and apply effects on the fly. From the main menu select Sequence > Render Entire Work Area.

To troubleshoot the issue we need to determine whether the flickering is a problem with the source file, reading the file, or previewing:

Are there any noticeable issues when looking through the video frame by frame?

Are you reading the file from a memory card or harddrive?

Did you render a preview of the sequence as described above?

If you export a short clip, do you see any issues with the output file?

Sorry. I should have been more clear.

I think we were confusing the word render (I work mainly in AE) I’d pressed “enter” which apparently wasn’t rendering all the clips, just the red line areas (artwork). The video clips remained with yellow lines. After I completely rendered the clips in the time line there was no flickering on playback within premiere.

No noticeable issues frame by frame.
Reading files from external drive (Firewire 800).
Previewed as described above and playback was flawless.
I exported 2 clips (422 & mp4) Both had no flickering and no visible issues.

Looks like the issue is when the video clips have yellow lines above them, some sort of realtime preview glitch. I don’t think it’s happened before with codecs other than h.264 in my case. It happens sporadically but now that I know when I completely render the timeline I can they disappear I can edit with confidence.

Thanks for your speedy replies and assistance.

Happy to help.

There are two types of renders for previewing: Render Effects in Work Area, and Render Entire Work Area. Enter is a shortcut to Render Effects. Adobe Help provides a brief description.

Hey Ivan,
I have the same problem. There is white color flicker in the program monitor but the source monitor is flicker free. The rendered output also has the flicker.

Please help.
