recapturing problem

jimingo wrote on 12/31/2004, 12:41 AM
I recently finished editing a wedding video. I saved both my .veg and vidcap files. Now I want to re-edit a portion of the video. When vegas recaptures my offline media and loads it into my project, nothing's in the right place. I don't understand why my video isn't exactly the same as before. I loaded the right dv tapes and there were no breaks in the timecode. I originally captured the media as three complete tapes and named them as tape 1, tape 2, and tape 3. Now when I put those same tapes into the computer, my timeline uses the wrong parts of the tape and in some parts even uses the completely wrong tape.

Can anyone help?

While far cleverer people are waking up . . have you got Enable DV Device control in VidCap Prefs? Vegas needs to be able to control the DV tape to get to what it wants. This is just a wild guess . . can't do any wrong?

Another thought: Are you absolutely sure you originally Named the tapes for the VidCap procedure, correctly? I've made this mistake.

Yeah, I'm sure I named everything correctly and I do have enable dv device control turned on. This happens with every project when I recapture, not just this one.

Try a small Recpature of just one Event - replacing & removing each and every tape until you get back in swing with what you have. T/Cs should be identifiable on each and every separate tape. BUT each tape has to be correctly named. If you've got an Event saying Tape1 IN 00:12:00 OUT 00:14:00, if you haven'et NAMED the tapes corectly within VidCap then a this "range" could be picked from any of the 3 tapes. Well that's my guess. You sure you aren't picking off a VidCap that was from another project? Ho .. done that before too!

Have you openned the correct veg?

I know I named the vidcap right because one of my tapes matches up.
I also captured the tapes as one big clip so I only have three clips to capture...Tape 1, Tape 2, and Tape 3. Tape 3 matches, Tape 1 and 2 are in the general area of where they are supposed to be, so I know they are also named correctly. But how do I go about getting the clip (For example tape 1) to start at a different timecode location without rearanging the clips on the timeline?

Yeah, it's definately the correct veg because the photo montage and other sections of the video match up perfectly. (Mostly the media that I didn't have to recapture)

Sounds like you are doing everything correctly. Tell me .. just another thought, before I start earning money - HAH! - these missing events, they aren't, render clips you have worked on and now have deleted from your HD . .. nah .. you wouldn't do that.

No, I have no missing clips. It seems as if Vegas is reading the wrong timecode somehow, but this is happening everytime I recapture offline media.
When I ran into this problem before, I got around it by recapturing the clips as different names, and then replaced the clips within my projects with the new clips. But that won't work this time, the tapes are still a little off.

You haven't changed underlying prohect prefs? NTSC<>PAL? Frames . .. ? Can't see how any of that wuold make a difference . . T/C is T/C yes or no?

Nope, all the preferances and properties are the same. For some reason vegas is starting the recaptured clips at the wrong timecode, and loops them. Everythings screwed up. Thanks for helping anyway.

Jimingo,

you say that all the events from tape three fall into place but the events from tapes one and two. You also say that the events from tapes one and two are actually showing media from those tapes but not the right segments.

Someone is going to make a lucky guess.

How about this. When vidcap recaptures media it has preroll. This can be set in vidcap prefs. maybe you want to shorten it.
OR,
maybe since you captured the tape in one fell swoop there's no space for the preroll and that's messing things up
OR
Maybe these tapes are reused and there's smidgeon of "other" TC at the head of the tape.

So how about this. For tapes one and two, when you recapture, Vidcap shows these as batch captures. Why not edit the in points of these two to start about 10 seconds farther into the tape? Then when you start the capture, make sure the heads are sitting on top of good time code.

Assuming you captured in Vegas originally and assuming your source is DV with timecode, you should be able to to open a Vegas project, go to the media pool, and select "recapture all offline media" complete the capture process... and wind up with an accurate recapture.

Is this your recapture process? If not, how is your process different?

I do recapture from a vegas project and my source is dv footage. My pre-roll is turned off and my scene varification is turned on. Still, all clips from tape 1 and tape 2 are off by about a second or so. I guess I could fix each clip but I've made tons of edits so that would be like redoing the entire project. When I batch capture tapes 1 and 2, the bar that shows the percentage of the clips captured never reaches 100 percent. For some reason, the bar only gets to 99 percent as if it needs to capture a few more frames, but theres nothing left to capture and there never was. This may have something to do with my problem but I don't know why this is happening. Cany anyone help?

Seems like if you're capturing an entire tape as one file you don't need scene detection turned on. But I suppose it doesn't interfere.

This is wierd and I've never run into this. Could it be something like "use custom timecode" in the media properties?

Yes, I had the same thought, Rob - try turning scene detection off - you also said something about a clip looping - this wouldn't normally happen if it were part of a single clip from a camera tape, so I wondered then if Vegas was recapturing separate clips for events.

Something else to try, at least ...
rmack350 wrote on 1/1/2005, 9:37 PM
Yeah. "and loops them". Shouldn't do that unless maybe they're subclips?

I actually meant start frame verification, not scene detection.
But anyway, I kind of found the problem...somehow when I originally captured the video, the timecode was not captured correctly for tapes 1 and 2. I guess there's nothing I can do to fix that but I'd really like to know why this keeps happening.

How do you know it wasn't captured correctly? What are you basing this on? Have you identified an offset? I want to know . . for my own education.

Because I went to the edit details window and checked the timecode in and out for a clip. My first clip's timecode was supposed to start at 00:00:00.06. But when I load the tape into my camera and check the timecode at 00:00:00.06, it's the wrong shot...it's about 2 seconds off. So that means that the original footage had to have been captured with the wrong timecode somehow.

Completely wild and off the wall guess here, but by any chance have you done a "Save as with copied & trimmed media"? I can imagine this playing havoc with the time timecodes.
jimingo wrote on 1/2/2005, 7:16 AM
nope, didn't copy and trim
rmack350 wrote on 1/2/2005, 9:47 AM
I think I have read about this problem on this forum. If you start your capture on a segment of wrong timecode (as might happen on a reused tape) you may find that your captures continue based on that timecode.

It's a guess. I find that I have trouble if I try to recapture something right at the front of the tape. I never actually need to capture anything there since it's just bars. Sometimes I just get lazy.

I wonder what timecode you'd see if you rewound the tape all the way to its stop. This timecode is only 6 frames in, not exactly an easy thing to recapture since you need some amount of preroll. In fact sometimes you'll be able to make this capture the first time because you "captured entire tape" but later on you won't be able to get it because you now need some preroll.

Maybe there's a solution here. Assuming that there was some unrelated timecode right at the head of your tape, maybe vidcap just took the timecode it saw and started adding as it captured. If so, maybe you can fix this by going into the media properties and setting a custom timecode starting at some point you'll have to determine. Do this in a new, clean project by dragging the offline media from the one project into the new one. Ideally you'd compare the tape to the previously captured media and find an easily identifiable frame at the beginning of it all for comparison, do a little math, and then set your custom timecode to start at 0 plus that difference. Of course, you've got a problem here-if you had the original captures you wouldn't need to deal with the problem.

I don't know whether setting a custom timecode will really do the trick. I'm assuming that what would happen is that you'd be altering the media's timeode and then the new capture would use the custom time.

Here are two things to consider for the future. First, stop capturing entire tapes. If you had captured clips, either automatically or by logging, I dare say that you'd only have this problem with the first clip. Second, put bars at the heads of your tapes. This way you don't have needed media sitting right at the very front of the tape. In this case the fouled up time code would be on the bars segment and you'd never even notice the problem.
