EX1 to Cineform workflow: how to best sync TWO cameras?

Say, there's a shoot with two EX1's.

Footage is transcoded into Cineform before editing.

Since Cineform (to the best of my knowledge) does not retain original timecode from MP4s, question arises:

- What is the best way to synchronize two cameras during the shoot, to avoid post-production headaches?

So far I was simply using a clapper, which is also a pain because both cameras need to clearly see it, and that is not always possible. Plus, start/stopping the cams multiple times requires clap sync each time. Not fun. And, manually finding the clap moment in the footage and aligning the clips in timeline is tedious and not precise.

Any better ways of doing so?

Maybe a flash - but then there's no loud accompanying sound like with clapper, which helps aligning the clips quickly. And, due to EX1's rolling shutter, it may not even capture the flash correctly!

What would you guys do?

I don't have an EX1, but when using Premiere with Cineform with footage from my FX1s/FX7s, I just visually align the audio waveforms. Just find the first audio peak in the clip and align it to the same peak in the corresponding clip from the other cam.

The challenges you are experiencing with using a clapper are the same ones faced by Hollywood, but it's just the nature of the beast. But the above method is easier.

Hi Alex,

Our next release will have timecode support for EX1 MP4s, so hopefully that will help with your multi-camera editing!

I like the idea of using a cheap camera flash unit. EASY to see and sync, and only bursts for a frame or two. Dead simple.

Tim - thanks, that'd be cool!

When do you think will you roll out beta for this? I use Prospect HD.
