    Big capture big problem

    Ok I'm in trouble heh big trouble.
    I bought marvel g450 and i thinking that i can capture with this card full screen video.
    First i tested software pc-vcr. It's ok but to small captur.this soft do segmented capture with 4 giga part.Ok After that i tested my favourite software-virtualdub. And
    ..... I can capture with full resolution with lots of codecs (mjpeg,divx itd) . I tested it on win2k on ntfs partition then i could do big video files over 4 giga! Ok But now is big problem i captured in YUY2 and it was ok but after magic 1hour 11 minutes (71minutes) captured end! I now its a bug of YUY2Ok then i tested captured multisegment with the same codec and with YUY2 and its the same error after 71 miutes capture stop!

    Im verry angry

    After that i was tested capture in RGB mode and now is another problem! n this mde i droped lots of frames??? And o don't now why!! because in YUY2 mode i have no dropped frames!!

    I tested capture on win2k and on win98SE and it is the same probelem!

    I slowly lose hope for capture with full resolution and in for example 2 hour time!!!

    What is the way to capture files 2 hour long
    with this card??????????

    I "fight" with this problem 2 days non stop!!
    and i'm verry angry (

    Video editing is my big hobby and when i bought this card i thinking that i can captured video with no problem!

    Thx for your help (if it was )

    sorry for english

    I've used this card to capture over four hours of video at a time. Try AVI_IO for your captures. It even offers timer record, just like PCVCR. Don't give up, the card can do what you want.

        ok i fight with this problem oall night
        and now i know why i loss frames in RGB mode

        In YUY2 mode when i capture in full PAL resolution i have 20-30% processor usage

        But when i captured in RGB mode i have !100% processor usage
        and this is with mjpeg compression and with no compression??

        And now is another problem why in RGB mode i have with no compression 100% processor usage??

        I have 1200 Athlon ,512 Ram


        thx for all reply

          Sounds to me like a bad sector somewhere near the end of your hard drive, causing the PC to lockup when you write to it. Do a scandisk with surface test.
          The high CPU usage is because of the (software) YUY2 -> RGB conversion. Avoid RGB if you can. It doesn't support full-frame PAL/Secam resolution anyway. And don't get angry too soon (take a deep breath and a Zubrówka) , the Marvel just isn't for the faint of heart...
          Resistance is futile - Microborg will assimilate you.

            i haven't bad sector!!

            Then what is the way to doing "big capture" with this card?

            Then i say YUY2 stop after 71 minutes .As i read in net lots of people has the same problem! with this mode (yuy2)

            I reinstal today my win2k and it is the same eroor now!

                I captured Huffyuv 704x480. Huffyuv is a "lossless" yuy codec that runs about 9 megs per second at that res. You can find the codec here .
