Thanks, for the great reply.

I did a test on a few shots using Resolve and essentially the process is:

1. Identify each flash frame by razor-blading the before frame, flash frame and after frame, to create a trio of three small clips for each flash frame.
2. Select and shift all of these frame trios up to a new track.
3. Copy and past all of the sets of three frames into a new timeline.
4. Make a one frame solid black clip, copy and paste this clip between every set of three frames and delete the empty spaces between sets.
5. Ripple delete flash frames from the center of each trio.
The timeline is now a pattern Before Flash-frame, After Flash-frame, Black Frame, Before Flash-frame, After Flash-frame, Black Frame….
6. Export the sequence as a single EXR sequence
7. Import the sequence as a clip into a new timeline, change the speed to 50% with optical flow and ripple sequence turned on.
8. Export the sequence as single EXR sequence
9. Import the sequence into a new timeline.
The sequence will now be Black Frame, Half Black Frame, Before Flash-frame, Intermediate Frame, After Flash-frame, Half Black Frame …
10. Razor blade out the intermediate frames. Shift them up to a new track. Copy and paste them into the original timeline. Move each intermediate frame over it’s corresponding flash frame.

The results of just that process have been pretty impressive. We’ve been playing “spot the flash frame” to see if we could tell where the new intermediate frames are without knowing! Looking like about 10 minutes of labor for a 10 second shot depending on the frequency of the errors, but the process can definitely be batched over a whole reel.

Cheers,
Ian
