Dropping over 60% frames during captures

[craig blanchette]

I have been fighting this problem for quite awhile now. I used to get good captures on my old machine (a p2). But now with the newer machine, captures are terrible. It doesn't matter if its 720x??? or 320x???, the frame droppage is the same.

Machine: p3 566, abit motherboard, 394mb pc133 ram, 20gb Maxtor ultra66 7200rpm with dma turned on, running Windows ME. Has directX installed and video update. Dazzle Video Editor card has its own irq. Camcorder is a Sony TRV720. Using t1 driver (because I can't find the Microsoft driver)

I have been working on this every day for weeks now with zero success... Can anybody help?

Which captureprogram are you using?

[hitechjunkie]

what was the O/S on the PII machine? based on the posts i've seen on the rec.video.desktop newsgroup, there appears to be a lot of users with similar DV capture problems under winME. a couple of notes i did see posted at a DV card tech support site about the TI driver is

- TI Camcorder drivers do not support batch capturing in Media Studio Pro and are not supported in Adobe Premiere 6.0; in those situations, you would use Microsoft camcorder driver instead.
- TI Camcorder drivers are not supported in Windows Millennium
- TI Camcorder drivers do not support DV SmartPlay.

also, there's some info on using Dazzle under WinMe at the Dazzle Tech Support Site

I am using Ulead video studio 4 which came with the dazzle card. I want to run premier but it does not support the dazzle card. I do not know of any other program that I could try. As far as an operating system on my p2 it would have been win98se

THIS MIGHT HELP WHEN CAPTURE DISABLE ALL BACKGROUND APPLICATIONS. EMAIL ME FOR FUTHER HELP

[hitechjunkie]

win98se? that's probably why it was working. MS DV driver is available for that O/S. based on what i've read, the correct winME driver for your card has to be provided by the manufacturer of the card, Dazzle, either from their website or thru their install CD. i'd try downloading the driver update from their tech support site and get away from that unsupported TI driver.

update: looks like dazzle doesn't provide it and it is up to ulead to provide a working driver for the card under winME. i guess you already knew that...

whoops again! here is ulead's stance on the subject:

<TABLE BORDER=0 ALIGN=CENTER WIDTH=85%><TR><TD><font size=-1>Quote:</font><HR size=1 color=black></TD></TR><TR><TD><FONT SIZE=-1><BLOCKQUOTE>Note for video products:
Although Ulead VideoStudio and MediaStudio Pro have no reported problems with Windows Me, there have been Windows Me compatibility problems with the device control drivers used. There are two kinds of device control drivers used with Ulead VideoStudio and MediaStudio Pro for capturing video with a DV camcorder and IEEE-1394 card. One is the Microsoft device control driver included with Windows 98SE, Windows Me and Windows 2000. The other is from TI. Some users have reported Microsoft and TI driver-related problems in using Ulead VideoStudio or MediaStudio Pro with Windows Me, including the "Fail to build the preview graph" error message. These problems are driver-related and not caused by Ulead VideoStudio or MediaStudio Pro. For questions on OS compatibility with your device control driver, see the driver manufacturer's Web site.

i'll shut up now...

Well, from all the research and messages I have recieved. I do believe that it ME thats the culprit. I will be doing the format and install of 98se this weekend and see how that goes... One nice thing is if this works I should be able to get some nice captures. I know so much more about this then I used to...

I have a pinnacle DC10+ which I use on a AMD K6 550 and Windows ME. I to started to get terrible frames dropped but it was traced back to the fact that I had changed my desktop settings to 32bit. Once I changed back to 16bit colour evrything worked fine again with great captures, so It is not ME in my case that was the fault.

Hope this helps

[craig blanchette]

I have the video settings on 16bit. Well I have everything up and running uder win 98se now and I still have 60% of the frames being dropped... grrr

I'am having somewhat of a familiar problem with Win98 and my AIW card, using Analog input to capture, dropping alot of frames something that wasn't happening on win2k, it was alot faster on win2k but i didn't stay on win2k because of AIW RADEON drivers for it suck badly!

Turn off any virus scan or screen saver programs. Are you using any video compression? If not you should be using huffyuv. What is the frame rate and resoultion set at?
