Capturing HDV footage – subclip problems

[Walter Biscardi]

Start / Stop Detect. Turn it off.

The Help Menu is a great thing in FCP.

I remember a post that was suggesting that when importing HDV footage FCP had to re-queue footage every time the camera was stopped, and I forget why but was it for purposes of pulldown removal or long-GOP format or am I just nuts?

Just trying to educate myself ahead of time, sooner or later I’m going to have to cut a project with the HD-110 that the boss bought…

Walter- Isn’t Start/Stop Detect a post capture function that let’s you locate timecode breaks in DV formats that WILL capture the entire reel, even if breaks are present? Start/Stop Detect is greyed out when an HDV clip is selected in Viewer, so it can’t be used to find HDV T/C breaks post capture either. Is this function somehow active during HDV capture? Is there a way to turn it off prior to HDV capture?

The problem imperialpnd is having is common with HDV tapes. In addition to breaks at timecode start/stops, some breaks also occur in continuous clips where no start/stop happened. The closest to a fix I have heard of is to set pre-roll and post-roll to 1 sec. This will reduce the lost material to 3-4 seconds, rather than 6-7 seconds with default pre/post roll settings. If you batch capture, some have had success by also setting Handles to 15 frames, reporting as little a 1 second of lost material. Still a problem at the lost sections where the camera WASN’T stopped. Sometimes hard to edit around. This is most commonly reported with JVC ProHD cameras, but I have mid clip breaks with a Canon XH A1 also.

Apple claims to be working on the problem.

On future shoots, the videographer should give 7 to 10 seconds of pre-roll on each camera start. Many of us have lost the art of pre-rolling since DV will capture over T/C breaks. HDV usually will not.

There are two places to reset to help capture the entire tape, In the L&C window find the Clip Setting tab and uncheck Create new clip on start/stop. and in the User Preferences General tab find On timecode break change to Warn After Capture. I like to have multiple clips made for me as it makes it so easy to rename the one’s I want and to trash the one’s I don’t.
Good Luck

JVC just posted the “fix” software for the HD100U/110U.

From JVC site:

“This upgrade is for owners of JVC’s 100 Series ProHD Camcorders purchased in the United States.”

https://pro.jvc.com/pro/attributes/HD…00110_upgrade/

This is not for the E models.

Warn after Capture works for DV, BetaSP, DigiBeta, HDCam and probably some other formats I have not used.

It does not work for HDV firewire capture in any of my editing/testing. It does not work for JVC HDV firewire capture even after the new JVC/FCP software upgrade “fix”. Any timecode problem just aborts the capture unless “Create a new clip…” is selected.

It’s a GOP thing.

imperialpnd did not say what the player or capture path was. Most are using the camera and firewire. Component to a Kona card and Capture Now will usually work to eliminate breaks at start / stop or the really annoying subclip breaks, but timecode references are lost. Picture quality is a bit lower than firewire capture too, but the GOP is removed before FCP sees the data stream.

Hi,

So im having this issue too, where on capturing a clip, fcp will break it up into anywhere from 2 to 25 pieces, and i lose 6 seconds of footage between each clip. I read what people have said in this thread, but my breaks are happening despite start/stop options being turned off, and even when the break happens in the middle of an interview where there was no start stop anyway. It happens even when warn after capture is selected, even when there is no time code break or dropped frames, and its not the tape stock.

So its either my canon A1 HDV camera, or FCP cant handle hdv well yet. Is that really it?

In the meantime, does anyone know a fix for this. Its insane to lose all this footage in the middle of an edit. Im at wits end.

thanks
ana

Is this happening on the minute mark, and could it be from recording non-drop frame and FC thinks it is DF?

[George Strother]

The sub-clipping is not on even minute marks. Pretty much random according to reports. Some think it is mostly related to drive write speed, with firewire drives over 50% full being to most suspect.

FCP 720p30 preset is NDF, camera default is NDF. Again according to numerous reports, not DF/NDF related.

You can find much more on the DVInfo.net JVC ProHD forum –

If I may quote me, I recently said –

“Component to a Kona card and Capture Now will usually work to eliminate breaks at start / stop or the really annoying subclip breaks, but timecode references are lost. Picture quality is a bit lower than firewire capture too, but the GOP is removed before FCP sees the data stream.”

Just a coupe of posts up.

This seems to beat most of the problems, but timecode is not captured with this method.
