Strobelights / Rolling Shutter

[Steve Crow]

Peter I don’t think there is anything you can do to correct this – the camera is capturing exactly what happened. In theory, if you removed every other frame (the frames filled with a flash) and then replaced that frame with a copy of the one before or after it, then all the flash frames would be removed but I still think it would look weird (slow motion? and off-sync)

There are tutorials online for ADDING flash effects to your video but I don’t think there can be any on removing them…maybe there is a creative work around I haven’t thought of however, let’s hope! 🙂

That’s what I thought as well… We discussed the problem before the shoot, but had no idea how to solve it. I hoped that – like in other projects – I would be able to “cut around” the flashes most of the time, but no chance here …

I thought about maybe stylizing the footage if everything else fails. Luckily this is not supposed to be a documentary but more like a “music-video-style mood-clip sort of thing”…

We had to capture the DJ-performance of an internationally very well-known musician, producer and film-composer and create a promo-clip for him.

That’s basically a great idea. Sync is not a problem. We won’t use the audio anyway, but get a completely different track. Strobing could be a problem, because of the missing frames… Hmmm… Maybe in After Effects: Remove the frame and interpolare the gap… Could work for single flashes, but we had a “thundestorm”…

But I think this could be a solution for a couple of shots. If I had to do all of them… Don’t even want to think about it 😉

Thanks a lot for the suggestion, Steve! Much appreciated! I’ll definitly play around with that!

Edit: Just want to add: The flashes per se don’t bother me at all. It’s the “half-frame” issue… Maybe (for selected shots): Mask the correctly-exposed part of the picture out and increase exposure for that part in post… Will try that as well
