DVX100 question for Sonic Dennis

Hi Dennis,

I'm a new Vegas user with a couple of AG-DVX100 cameras.

I've been reading your other thread regarding the DVX100. I am curious as to why you said 'You must have Video Capture set to create new clips for each scene.'

I'm brand new to Vegas. I've only done some tutorials and today was the first day I captured some video. I turned off the 'create new clips for each scene' because I'm not used to it. I come from 'Premiere' where it captured the whole clip as long as I was recording. This was the way I'm familair with editing, so I turned off that feature.

I captured only 60i today, so the prior thread about 24p didn't really apply to me at the moment.

But I am curious as to why that feature must be turned on for 24p. I'm doing some 24p soon so I would like to do it right the first time.

Thanks

Mark Briody

AFAIK Vegas does "scene" detection only on time code not based on any change in the scene. So as long as the camera is running, that's a scene regardless if its ten seconds or an hour or more because the starting time code hasn't changed. You turn the camera off or import an unrelated video it obviously would have different time stamp and be seen as a "different" scene. I myself much prefer just to import the whole ball of wax and break it up as needed on the timeline.

Mark:

Each 24p/24pA shot could start with a different pulldown cadence. Vegas only looks at the cadence of the first frame, and extrapolates from there. So, if you have a cadence break due to multiple shots captured as one clip, or if you had dropped frames, it may be removing pulldown incorrectly.

That said, I read that the AG-DVX100 only stops and starts 24p/pA recording on 5 (video) frame boundaries, so it would probably work to capture across boundaries if you were consistent in your mode, but it would still cause problems if you switched between 24p/24pA/30p/60i modes between shots.

It may also still work if you have dropped frames, because we don't "shorten" your video due to dropped frames, so the cadence shouldn't get messed up.

However, I think it's just safest to say that pulldown removal works best with scene detection "on" and you have no dropped frames.
