Hey people! Hope you're all well ?
I'm editing a 18min video recorded with two cameras (different brands, mirrorless cameras). I syncronized both cameras through the first slate, at the beginning of the videos. After 18min there's a second slate at the end of the recording. The footages are mismatching the "clap" by 2 frames and I've never faced this problem before. There's some audio drifting too.
What can cause this? How can I avoid it and fix it?
The tech is simple, but here it goes:
A7s - 29,97fps 1080p XAVC-S 50Mbps;
X-T3 - 29,97fps 4k Long GOP 100Mbps;
Timeline - 29,97fps 1080p.
Thank you ?
