JVC HD100U audio disjointed on capture

Leo,

What are your project settings?

Hello,

My project settings are the JVC HD100U presets from the Adobe website in the JVC HD100U 25p preset.

I managed to record some test footage and it still goes out of Sync. The clip is recorded as a MPEG, it seems very un-responsive when trying to play back in Adobe Premiere Pro 2.0 and After Effects 7 Pro, it lags the interfaces heavily.

I downloaded Cineform NEO earlier under the trial, it managed to record from the Tape via firewire cable in HDV mode from the JVC camera and recorded perfectly all in sync.

I used the stand alone capture. Once the clip was captured to AVI with Cineform Intermediate I could play back the clip in After Effects and Premiere Pro with no lag or freezing of the applications. It played smooth and the response of playing back and scrubbing the video was instant. The clip was 128×720 25/50 from the JVC camera.

So it seems that is is better to use Cineform over the HDV capture default in Premeire Pro when dealing with the JVC HD100U and other HDV cameras?

Thanks,

Leo

Check to see if it actually captured at 25 fps.

I’ve had this problem before. Or at least something that sounds similar.

Unfortunately I haven’t figured out a real good solution for it. I think it’s an issue with the compatibility between premiere and that camera. The JVC GY-HD100, right?

I at least troubleshot it down to it not being captured at the correct frame rate at times. It only happened occasionally. The video would move at regular speed but the audio would be fast. And my only solution thus far is to make sure to capture within the boundaries of when you turned on the camera for the shot and when you turned it off. So don’t start the capture before a cut at the beginning of the capture period, and don’t go over a cut for the end.

My theory is that for a split second when the camera was off, even if you wrote timecode to the tape already before shooting, the camera defaults back to 60i. I have no idea why… but the theory is based off one of the original problems the camera had which had to be patched a long time ago. It used to always default to DV and would constantly flash something like “change to DV 1394” when you had it set to capture HDV footage.

Anyway, if anyone knows why this is otherwise and how to fix it feel free to comment back, but the best way I’ve worked around the problem is capturing between cuts.

Hello,

I downloaded a 15 day trial of Cineform Prospect HD, and captured via the firwwire form the JVC HD100U camera and everything records perfect and is in Sync.

So I am looking into buying Cneform shortly along with Adobe Production Studio CS3.

Thanks,

Leo

Would love to hear whether the new Premiere CS3 is up to scratch with HDV finally – in all aspects. Have always been baffled by people who used 2.0 saying it could edit HDV, but you can’t actually get it off any worthwhile cameras without using 3rd party software.

So when you get it, maybe tag your results on the end of this thread as I for one am certainly interested in regards to the HD100.

Oh, well I have gotten lots of usable footage off the camera in HDV. It’s just on occasion when it changes up the frame rate and messes up the audio. For me, anyway.
I captured it all straight into Premiere Pro 2.0.

This was shot in the GY-HD100, 720 24p.
