Capture works for 13-17 seconds then errors.

Post by CorpITS »

Hello,

I'm having difficulties using DVD Workshop to capture video from a VCR. The capture works for about 13-17 seconds each time and then quits with the error message "Failed in capturing. The file may be corrupted. Do you want to delete this file? [1301:5:692]"

I have tried using multiple codecs, various levels of compression, and disabling the sound capture. Nothing seems to affect the problem. However, Windows Movie Maker works fine. Transcoding into DVD Workshop the 40 minute .WMV I captured using Movie Maker took almost 10 hours though. Since I have to try to squeeze 4 hours of video onto this DVD, waiting 2.5 days to transcode really isn't a workable solution.

My system is: WinXP Pro SP2, 512 MB RAM, 2.0gHz CPU, capturing to an NTFS volume on an IDE drive with about 4 GB free on it. The capture card I'm using is an ATI Theater 550 Pro.

Any suggestions would be greatly appreciated. Thank you.

Capturing to a volume with 4Gb free on it :shock: Did you at least defrag it? How big is the disk alltogether?

Make that 7 GB. Looked at the wrong drive, sorry. Even capturing to a thrid drive with 17 GB free, the same problem exists.

Do you get the same capture duration before the error or does it vary when utilising the other disk?

Still, 7 or 13 Gb free space is nothing when it comes to capturing video. I have a total of 380 Gb on 4 HDD's on my system and never encountered your type of problem. Never used a system with less than 60 Gb, ~ 40 Gb free, to capture in the old days either.

Still think your problem is disk space related.

On reading your original post again, are you capturing analog video to mpeg?

If yes, your system may not be up to it. What else is running/installed to the system tray while doing the capture?

Thanks for trying to help me out.

I've pretty much disabled all background processes that aren't essential.

What I'm trying to do is take a corporate training seminar that was recorded onto VHS and convert it to a single DVD. The seminar runs about 4 hours and is spanned across 3 VHS tapes. The source tape is of pretty marginal quality, so I should be able compress it down pretty far without anyone really complaining.

I'm quite computer literate, just not too up on video editing. Do you have suggestions on how I should procede?

Like heinz-oz said, you computer might not be able to keep-up with the MPEG compression in real-time. MPEG compression requires lots of number crunching. The general rule is to capture in AVI format which is less lossy (and less compressed). Clearly, you are not running out of disc space in 15 seconds. AVI eats-up about 13GB per hour. MPEG typically eats-up about 3GB per hour. After the video is captured & digitized, your CPU can take as much time as it needs to perform the MPEG encoding.

Workshop needs some "working space" too. I might be wrong about this... but it seems if I have a 4.7GB MPEG, Workshop wants another 9GB when I make a DVD. Of course video editing requires twice as much space as the original file too. You don't edit the original... You create a new-edited copy. (It sounds like you are not editing this project.)

The ATI cards are the most popular line of capture cards, and they should work with Workshop. But, you could try the software that came with the hardware. Capture devices are not as standardized as common computer peripherals like printers.

I have a Hauppauge capture card, which has a hardware MPEG encoder. I use the Hauppauge software for capture, and it works great. But, it's MPEG only and MPEG files are not meant to be edited (mostly because editing requires two lossy encodes).

You still have not given any details on what hardware you have available. I think it is aparent that your system is not coping with the task at hand. To capture to DV AVI you would need to have a converter of sorts, like a DV camcorder with AV (analog) in / DV AVI out feature. You would also need a firewire port on your PC and a firewire cable.

The problem I see with that, from the limited info I have, is likely to be disk space. Relatively uncompressed (~10-11% as standard) DV AVI comes in at about 19 GB/hour. It does not strain your PC resources though. All you would need is pretty much a standard, modern day, PC.

In the early days, I have captured DV on a PII 400MHz WIN 98 machine and 5600rpm HDD with only a few dropped frames. Replacing the 5600rpm disk with a 7200rpm disk fixed that.

Can you see a way to get this going?

Unfortunatly, this ATI doesn't include any bundled editing software. The instructions just tell me to use Windows Movie Maker. :-\ The card also includes a TV tuner and the software bundle seems more focused on that
feature. Which codec do you recommend that I capture with, if I compress to MPEG afterwards?

heinz-oz, I'm not using DV. I have a normal VHS VCR plugged directly into the capture card via an analog composite video cable.

Sorry if I wasn't clear enough on that, I knew you had no DV. The thing is though, if you have a digital camcorder with AV-In port, you can hook up your VCR to that port and use the digital-out port on the camcorder to connect to the PC. That way, the camcorder does the conversion to digital format. I capture all my analog source material that way, even though I have an analog capture card from DVICO, paid in excess of A$ 800.- for it, but found it too cumbersome to use. The quality is not that good either.

I don't know the capabilities of the ATI card but daubt that you can use it to capture digital AVI with it from an analog source. It will only capture the analog signal and compress this to mpg2 for DVD. To do that it needs ample PC power to do the number crunching in software and your PC does not seem to be up to it.

You wouldn't be in the market for an analog capture card, would you :oops:

Ah, thanks for the clarification, Heinz. Too bad that I don't have a DV camera though. And I was in the market for an analog card before I bought this one last week. :lol:

What I'm going to do is get ahold of a 7200rpm 160GB Seagate Barracuda HDD next week. I'll just capture an AVI stream and then compress it to MPEG. Do you recommend any particular codec?

I checked-out the ATI website, and here's what I think... But I'm not sure... It's not really that clear...

You have an MPEG hardware encoder. So, yon't need an MPEG codec, and your CPU speed and RAM are not an issue.

Your card can only capture in MPEG. You can't use an AVI codec. (Ulead's software may not interface with this type of hardware.)

You can use that "TV-Tuner" software to capture composite video. Just like a TV, there will be a way to select the video (and audio) input instead of the cable-TV input / channel.

Once you have a captured MPEG file, you can open the file with DVD Workshop, and author a DVD.
