Analog Capture at 200 frames/sec? WhY?

dannyrod · Post by **dannyrod** » Fri Jul 29, 2005 8:19 pm

Hi, I am a newbie but I am trying to capture from VHS tapes to the computer using a usb device (Dazzle DVC 80) and composite cables from the VCR to the device. Everytime I capture some of the video, it plays back at around 150-200 frames. I have tried all kinds of settings and don't know know what's going on. I tried changing the codecs and the file types to capture to and nothing. Can anybody help out on how to capture at regular 30 frames/sec?

What are you using to play back the video? Have you tried right-clicking on the file in UVS and displaying the file properties to see what the framerate in the file header indicates?

I tried using both the windows media player and playing it back in VS. When I check the properties it actually says the framerate is that amount (in my case, between 150 and 200).

That's an unheard-of framerate -- what program do you use to capture? Can you display the media clip properties in UVS, copy them to the clipboard, and paste them in this thread? You may also want to download GSpot and have it verify the file properties to make sure the header information matches the contents.

I am using UVS SE 7 to capture the video. Here is the copy of the properties:

I installed GSpot and it actually says the file duration is 15 seconds instead of 2.09. It also says the framerate 29.970. Why is the header info in UVS different and why does it still play so fast?

THoff · Post by **THoff** » Fri Jul 29, 2005 9:25 pm

The root cause is the wrong framerate information. Because the header tells UVS (and Windows Media Player for that matter) that ~200 frames make up one second of video, these programs rip through the file in no time during playback, probably dropping frames to keep up with the indicated framerate.

So the question is, why is the header wrong? I would try selecting a different codec, and possibly a different capture plugin. Is this a brand-new installation of UVS, or were you able to use it successfully in the past? Have you applied the V7.01 patch from HERE?

Well, I tried every single codec in the list as well as all the capture plug-ins and they didn't work. It is a brand new installation of UVS and I didn't know there was a patch so I guess I will be trying that then. BTW, thanks for the help so far.

Well, I finally got a chance to try again after installing the patch and it didn't work. I don't know what else to do.

Danny,

I remember seeing lots of complaints about Dazzle capture boxes at www.VideoHelp.com. Do a search at this web site for possible info about your bizarre problem.

John

PS: I just did a search on the Dazzle DVC 80 and saw a rather long list of user complaints and rather unflattering comments about this device... Looks like you might want to exchange it for something better.

Thanks for the help.
