Capturing clips by length + capture format

Zapa wrote on 7/1/2005, 7:51 AM

Hi all... I'm a proud user of the Vegas + Blackmagic duo and after a couple of weeks checking the stuff there are two things that are not solved to me yet.

The first is that is impossible to me to capture by length in batch capture. I put the IN point an then the length but there is no way to introduce the data. Neither pressing tab nor enter nor intro. The box remains the same until i put an OUT point, then the length box displays the correct duration of the clip but i have to calculate it, of course... Is there a way to put the length and Vegas do the job of calculate the IN or OUT point of the capture?

The second question is about the clip format on capturing. When I see the properties of the clip it says that is an XVID video. I thought that the combination of Vegas and the Blackmagic were capable of capture with no compression. I haven't found any dropdown list of codecs in the preferences to choose the format of the clips captured with Vegas. Is it really possible to capture with no compression?

My sistem: Dual Xeon, 2 gigs ram, Win XP prof, Vegas 6a build99

Thanks to all!

I've never used any of the Blackmagic gear so others can correct any errors.

#1. You have to set both IN & OUT points in vidcap. This is a holdover from the linear (tape-based) days and that's the way most NLEs still do it. There's no way around this that I'm aware of.
#2. XVid is not a valid capture format, only DV-NTSC (or PAL, as the case may be). This is obviously a clip that you got from the net or someone else. You might be able to bring the clip into your media pool so try experimenting with it.
#3. You can't capture uncompressed with Vegas (does Blackmagic even allow this??), only render it out.
#4. Upgrade to 6.0b as it has several bugfixes.

Hi rs170a and thanks for your quick answer.

>>#1. You have to set both IN & OUT points in vidcap. This is a holdover from the linear (tape-based) days and that's the way most NLEs still do it. There's no way around this that I'm aware of.

Well, I think that the normal thing in NLE software is the possibility of different ways of point edit . In my case I checked the possibility of capture clips with IN point and length in Premiere, Discreet Edit... and all of this programs can do it. When you put the length and IN point, the OUT point is calculated automatically (or IN point if you put OUT point and length). Is only a substract operation but i'm too lazy to count frames, specially if the program can do it for you, uff...
By the way, I use the built-in capture program of Vegas, not Vidcap. Vidcap is incompatible with Blackmagic cards so i have to use the other way.

>>#2. XVid is not a valid capture format, only DV-NTSC (or PAL, as the case may be). This is obviously a clip that you got from the net or someone else. You might be able to bring the clip into your media pool so try experimenting with it.

I assure to you that are the clips that i just have capture. They have the name i entered and the date and time of the file are correct. I can hadle them normally in the media pool and the timeline. I forgot to say that I'm obviously using Blackmagic card for capture (not DV camcorder) from a Digital Betacam by SDI.

>>#3. You can't capture uncompressed with Vegas (does Blackmagic even allow this??), only render it out.

Well, not too much days ago, in the home page of blackmagic (http://www.blackmagic-design.com) was a huge advertise with a picture of vegas packaging and the lead was "Vegas goes uncompressed with blackmagic" or something like that. Is for that reason that i was asking for.

#4. Upgrade to 6.0b as it has several bugfixes.

You're right. The gold rule! I'll update and re-post the results.

Thank you again!
