iuVCR - system requirement question

[perempe]

Hi,

I've tried to capture with iuVCR in 720x576 (PAL, Full D1 resolution), 25Frame/sec quality 85, Xvid codec with my Athlon XP 1700+, 768MB Ram. It drops about 5 frames/sec. Does it work OK with better P4? (I hope U have one. Please try it for me!)

Please write me your experiences!

try virtual vcr =)

Won't you try it for me?

XviD codec is not real time, you can't do it. Don't try.

You can capture in MJPEG or HUFFYUV with zero dropped frames in full D1. Edit then convert after the capture. This will run 9 to 30 GB per hour.

But xvid is great codec, I would use it because it is much shorter than HUFFYUV. An hour would be 3.4 GB with good quality full D1.

But your computer isn't fast enough to do it, is it? Not if your dropping 15 frames per second.

If it takes you 20 minutes to encode 10 minutes of DVD video, you can't capture in realtime. It's a poor analogy, since you not converting MPEG2 to XviD. Your actually converting RAW video to XviD. You can test it by converting a short video to RAW, then timing your encode to XviD.

Try dropping down to 320x240 and you can probably do it. Dropped frames make a mess in MPEG4. You should use the Audio to maintain sync, that way you don't get lipsync errors.

iuVCR shows me the the framedrop level exactly. I have 4-5 dropped frames per second. (20 frame instead of 25.) Audio is in sync, that's the big advantage of iuVCR. Would it work with P4? That's all I want to know.

I capture using iuvcr at 720x576 25fps (PAL) using a Hauppauge WinTV card. My system is a Athlon 2400+ with 1G DDR ram, 80G C ane 250G drive on different IDE channels (I capture to the 250G drive). I am using a SIS based MD and a SB Live 5.1 (bypassing on onboard C-Media sound)

I just finished a 60 minute capture using PivVideo MJPEG with no dropped frames at all and I was also ftp'sing 5G to my machine from another on the home network to the C drive at the same time. CPU load averaged about 30% during the capture

I did try VirtualVCR a few days ago when I had a problem with iuvcr. Not so easy to use and I never was able to solve audio sync problems.

Do you have dynamic audio resampling enabled?

I tried every option available and read the articles on sync issues and potential solutions on the forums. Best I was able to achieve was to set a 250ms delay in the sound which made the sound in sync at the beginning. But it slowly got out of sync. As iuvcr works fine for me (no sync issues), easier interface etc. (and I did pay for it!) there is no reason for me to look further at VirtualVCR
