    Hi everyone!

    I'm tired of capture problems and I want to solve it once for all! You can check my computer specs on the link above and please help me. What OS I should use, if I need install some aditional drivers, etc... At least I want to capture at 640x480 YUY2 with PicVideo quality 18 WITHOUT LOOSING SYNC OR DECREASING THE FRAME RATE (the main reasons of this post)! I think if you can help me, you can help another user with have the same/similar problem (I'm not the only one ).

    Please help me!!!!
    Thanks in advance

  2. You have the right OS. The problem is your processor. At 550 mhz, you are going to drop frames at high resolutions. It could also be ur chipset on your motherboard, ram, etc... As for your capture card I am not sure about that either.

    With a Athlon 1,1GHz (256k cache) with a Soyo Motherboard (VIA Chipset), can I get better results?
    Remember my PIII 500 haves 512k cache...

  5. Its better to have 512k of cache. If you are using Virtual Dub to capture make sure you Lock video to audio stream checked under capture/settings.

    But when I try to capture with VirtualDub I drop lots of frames
    :/
    How I can solve this? I can capture without drop frames with AMCAP, but without sync too...

  7. Ok, makesure that you have DMA enabled on your harddrives. Also, make sure you are not using any filters, because these will you more cpu and cause u to loose more frames especially at high resoultions.

    DMA is enable on my HD and i'm not using any filters. I always get bad results with VirtualDub
    How I can get good results?

  9. I think your video is out of sync because you are dropping frames. A 550 mhz processor just isn't fast enough to compress all the data that is coming in. It may say you're not you probably are with AMCAP. You might try capturing to uncompressed format vith virtualdub with no compression on the video or audio. Then you can reencode it later with virtual dub or TMPGENC. Or HuffyYUV codec might work cause it isn't so highly compressed on video. I have a AMD T-Bird 1.3 MHZ processor this is my preffered way of capturing video (uncompressed and reencode later to SVCD). The drawback is you need WINDOWS 2000 or WINDOWS XP and the drive you capture to needs to be NTFS file system format to avoid the 2 gig limitation. I have a 80 gig Hard drive dedicated to video capture.

    Before you try anything serious run a couple of tests with AVI_IO.

    My last system was similar to yours and whilst VirtualDub (and other apps) dropped frames, AVI_IO gave me a rock solid capture everytime.

  11. That isn't neccessarily right. I used to have a Celeron 533 mhz and it did fine with virtual dub capturing with MJPEG at 18 at 640x480. The problem might be the TV card. If it is USB then this is why. If you can give me the site that shows the specs of your Card then I can assist you further.

    Not yet, because i've captured some videos with AMCAP without drop any frames and loose sync in the end of the file. I wasn't planing to capture uncompressed because it requires a lot of disk space and I have only 12 GB free to capture...

    I've tried with AVI_IO and I drop frames too. The most strange: the I/O value when capturing is low (about 1/2)...

    I don't believe you can capture with VirtualDub at 640x480 with Picvideo 18 under your Celeron!!! My TV card is PCI. I think my problem is have a VIA motherboard

  13. If you can give me the website and model of your Card it would help greatly. Also check windows updates for updates and install. Also check updates for your motherboard.

  14. BTW, make sure you have nothing running in the backround. And yes I did capture at 640x480 using the pic video codec at 18. Make sure your audio is set to uncompressed too.

    My capture card is Pixelview PlayTV Pro and the website is: http://www.prolink-usa.com
    I'm using different drivers of the original to get higher resolution... But it's not the problem because everyone use it perfectly.

    About running in the background, I have not when capturing, I always close everything which isn't necessary. I'm capturing the audio uncompressed.

    When you capture with your Celeron at 640x480 with PicVideo you got perfect sync? What capture program you use?

  16. Yes, I got perfect sync and I was using Virtual Dub. How fast is your harddrive. This plays an important role in capturing. Make sure you have defragmented and there are no errors as well. I could help you better if I could talk to you live. If you have AOL Instant Messenger (AIM) please Instant message me. My Screen Name is TommyDee291 . I would be glad to help you. If you don't have AIM go to http://www.aim.com

  17. Also, what frame rate are you capturing at? 29.97 for NTSC and 25 for PAL. Before I forget also, what source are you capturing from. Make sure there are no distortions or noise.

    I don't know how fast is my harddrive, but I think it's fast to do capture in that way because it's relative new. I've defragmented my HD and no got errors, 100% perfect. About AIM, I don't have it, i'll download today and talk with you.
    I always capture at 29,97. The sync goes out with cleaner or noiser sources.
