Using iPhone 29.98 and Canon T2i 29.97 in Project

Hello:

I've edited a 20 minute project using footage from my iPhone and Canon Rebel T2i. The iPhone was set to 29.98 and Canon T2i was set to 29.97.

I made a sequence of each video clip so I could key out the green and adjust the color before editing; then I synchronized all those resulting sequences into the project based on their audio. The sequences made from "iPhone clips" were 29.98 44100 1280x720. The sequences made from "Canon clips" were 29.97 48000 1920x1080. I'm using 29.98 44100 1280x720 as my general output for the project.

 

Here's the problem: When I render the project, the iPhone shots are in perfect sync with the audio. However, almost* all of the Canon shots look LATE BY (I'm guessing) 4-8 FRAMES compared to the audio.

 

Questions:

1) I discovered one sequence at about 2 minutes into the project that is set for 29.97 48000. *Even the Canon shots seem to be in sync BEFORE this one sequence but out of sync AFTER this sequence. Can I just manually change the sequence settings to 29.98 44100 for this one sequence and might that help?

2) Would it help to manually change the original Canon sequence settings to 29.98 44100 as well (even though they were probaby "converted" when added to the larger sequences. (These are the sequences that appear 4-8 frames late in the overall project.)

The project is so close to being done that I don't want to screw something up at this point. But the sync problems are a bit distracting.

Thanks for any help you can provide.

Kevin

If the phone footage is variable framerate convert to constant framerate with Handbrake before bringing into Premiere.
