Desincronized footage.

I have the same scene recorded with 2 different cameras. However, as time passes, the action is desincronized. Why? No frames were lost while capturing. is it possible the cheap camera records in non real time?

I came up with the solution. Because of the relativy theory, one camera goes closer to light speed and therefore, time passes slower!

:-DDD



Come on guys, any explanation?

Wow, interesting concept. I don't know, some older cameras might have different speeds after a whole lot of shooting. Maybe wear and tear. ?

One is DVX100e and the other one canon mv600.
After 12 minutes, the footage of the panasonic is 2 seconds ahead. Why!

tape glitch or capture error

You probably experienced a glitch or timecode problem in one of the tapes. This could have happened in camera while shooting, or during capture. Most likely, it was a bad tape or other camera glitch. If this happens again, have your camera professionally serviced.

I recently experienced a similar problem where after a certain point -- signalled by a loud audio glitch -- out-of-synch footage from two tracks became perfectly synchronized. Even though the timecode was solid, there was an obvious "skip" of some kind -- almost as if my assistant quickly pressed the Record/Pause button, but not long enough for the camera to stop shooting. I know that sounds weird, but that's what I saw, and I suspect that "shift" is responsible for my out-of-synch footage. After that audio glitch, the rest of the camera #2 footage (JVC GY-DV300U) matched up fine with my footage (Panasonic AG-DVC80).

I've synched my DVC80 footage plenty of times to GL-2s and another DVC80, and never had a problem. This was my first time synching with JVC footage. Digital is digital, so I don't think the brand of camera really matters. LIke I said, I suspect either a tape glitch or capture problem. If I really wanted to play detective, I could recapture the JVC footage and create a test project, but I don't have time for that. I will grill my assistant and see if he's had this problem with other projects using his GY-DV300U. After this, I'm wary of working with that camera again.

Good luck,

T.J.

is the DVX100 in 24p mode?

the canon only shoots in 60i (or perhaps 50i in this case) and if the DVX isn't set for the same, then the frame rates will obviously differ in postproduction.
