Dropping Frames (and didnt find help in other topics)

[ILJR]

Hi, I'm dropping Frames. Not 1 or 2, you can expect 25 dropped Frames out of 100 recorded Frames.

I read about every Topic where dropped Frames where discussed, but couldn't find help for me.

My System:
- Win 2K SP2
- AMD Duron 1000
- 20 + 60 GB IBM IDE
- 768 MB RAM
- SB Live Player 1024
- ASUS V6800 Deluxe
- PAL VCR

I tried capturing with ASUS Digital VCR which works fine in MPEG1 without dropping frames, and even in MPEG2, but the Quality is gross.
Then i tried VDub, AVI_IO, FreeVCR, for capturing AVI (and wanting to convert to MPG1/2 later with TMPGEnc.), dropping lots of frames in every resolution, with Huffyuv, uncompressed, and also PicVideo - even DivX 5 didn't work. My CPU is never used over 60%, every program i could disable in Autostart (regedit, Autostart-Group), and even with the TaskManager.

The HD is defragmented, so that problem could not be the cause, and DMA is also enabled.

Would be glad if someone could help

hi,
I'm still semi-new to capturing but i learned some stuff that really seems to help. what resolution are you capturing in? what color depth(24bit RGB or some YUV combination)? Is over view turned off? what are your settings for audio capture(44.1, 48, stereo, mono)? You may want to update to directx 8.1 and get the latest 4in1 drivers(if your motherboard has a via chipset). Also, since your running win2k use iuvcr, I hear that it is the best for WDM captures. with a little more information I think I could help you.

[ILJR]

Well as i said i tried to capture in various res. 352x288, 640x480, 720x576, cause of PAL Format.
Colormode is UYVY, others aren't supported by my card.

What do you mean by "Is over view turned off?" In VDub I've got the "Hide on Capture" option set if it's that.
My Motherboard is an ECS Elitegroup K7S5A (SIS 735 Chipset)..
Audio settings are 44.1, Stereo, 16Bit (PCM).

I tried to get iuVCR working, but after installing, all it did was crashing my computer (Rebooting) when i tried to start the program.

I'll update to dX 8.1 now, but don't think it'll work.

Thx anyway

alright, you know what, u have insipred me to make a guide....this will take about an hour, hope you can wait that long.

[ILJR]

heehee

Installed the TechnoGarb drivers by now (after deinstalling WDM and Nvidia-Drivers), hope to get it work now, but I'm interested in your Guide as well

It's 12:30 am already, but i'll stay up another hour i guess...
installing dX 8.1 right now.

[edit]DirectX 8.1 didn't help, as well as the TechnoGarb drivers didn't. I even got iuVCR working now, but it drops frames as well.
Thought my HD might be a little weak in the knees, so it isn't fast enough for the capture, any idea how i can check on that?[/edit]

I too have an ASUS V6800 Deluxe and am running Windows 2000 Pro. Last Wednesday (April 24th) I reinstalled Windows and wrote down everything I did. In the end, video capture using VirtualDub 1.4.9 worked perfectly. So here it is, take it however you want...

From a fresh Win2K Pro install (not a SINGLE thing modified)...

1) Install SP2
<reboot>

2) WindowsUpdate.Microsoft.Com
- Installed all available critical updates
<reboot>

3) WindowsUpdate.Microsoft.Com
- Installed the Win2K Security Rollup
<reboot>

4) WindowsUpdate.Microsoft.Com
- Installed IE6
<reboot>

5) WindowsUpdate.Microsoft.Com
- Installed any remaining Critical Updates
- MSN 4.6
- Root Cert's Update
- 2000 Compatibility Updates
- Mouse Driver
- Keyboard Driver
<reboot>

6) Manual download/install of the DirectX 8.1 Runtime
<reboot>

7) Installed ASUS Video Drivers v21.81a
<reboot>

8) Installed the nVidia Refresh-rate Fix
<reboot>

9) Disabled the "avnshell.exe" tasktray program and installed the nVidia WDM Video Capture drivers, v1.04
<reboot>

At this point, I fired up VirtualDub 1.4.9 and tested my video capture.. worked just fine... the usual 22 frames dropped per HOUR of video captured... same as it did before

Hope you can get some use of that.

Don't bother with those TechnoGarb drivers or any registry hacks/patches, you don't need them.

i have run into a snafu with screen shots, the only decent program seems to be hypersnap-dx, but that stupid logo is covering what i need to show.
if anyone wants to give me a better program or a "work aroud" for hypersnap, feel free. thanx, hang in there ILJR

[monsoon01]

The guide is up, and its quite decent if I must say so myself. check it out anytime, and don't forget to comment, lol.

Doesn't your Print Screen key copy the display to the clipboard - to be pasted into a image editor say?

Re Virtual Dub and dropped frames....

Have you experimented with the Capture menu Disk I/O settings.
I've found that more smaller buffer chunks help captures at lower resolutions, say 8 chunks of 512KB for 352x288.

But that capturing at higher resolutions requires larger buffer chunks 1M or more depending on the resolution.
Then experiment with the number of buffer chunks for an optimal setting.

thx monsoon, but where can i find the guide?

@HillJack: Nice, maybe i'll try another time, but my system's way to configured to just reinstall all that shit in here thx anyway, maybe i'll have to reinstall win2k anyway in the next weeks, so I'll see then.
BTW: what kind of system do you have?

@zed: thought the bufferchunks were for the internal testing of VDub only? Hmmm i'll can try that, although i would wonder about that causing the trouble.

[edit]nope zed, doesn't change a thing [/edit]

What are you capping from? I see PAL VCR above so I am assuming it's from that? There have been a number of posts about problems with old tapes causing exactly what you mention. I also had problems like that with 10 yr old 8mm tape and only solved it with a different cam. Something about missing time base information on the tape I think but I can't be sure. So, maybe it's the tape or the VCR? Try swapping one or both to see if it makes a difference, assuming you can borrow another VCR. Or try some other video source.

Good luck.

[ILJR]

my system only mentions PAL VCR, but i had already tried capping from various tapes, as well as from my satellite receiver, same crap here as there

the VCR is a Grundig, bought last year, guess can't be that old...

@ILJR,

I did not mean to reinstall windows, I only meant "here's what I have installed... do you have all this stuff installed?" ie: do we have the same stuff working for us.

Check version #'s and all that. Obviously there is something key to your problem, like disabling the avnshell.exe or manually installing DirectX 8.1 or something like that. I was simply giving the minimum requirements for it to work perfectly. Since yours still doesnt work, your missing something I have done, and that was my list

[ILJR]

Ah I See... i have the newest drivers... from NVIDIA (28.??) as well as MS.

Also DirextX 8, and all the crucial updates from MS.. what i won't install is for Example IE6

I disabled ANVSHell the moment it touched my HD

I have WDM 1.08, and don't think that would change much, would it?

[pieter145]

Did you look at the virtual dub help file "dropped frames and how to avoid them" (Video capture-tips).
The last tip worked for me (about Average Frame Rate value)
Good luck

[monsoon01]

ILJR,
the guide is up, u can find it here: http://forum.vcdhelp.com/viewtopic.php?t=89899[/url]

[ILJR]

thx, but both tips didn't work for me

[monsoon01]

well, ILJR, without getting down and dirty with your computer i dont know what to tell ya. try some of my tips in AVI_IO and see if that helps

[HillJack]

@ILJR

You are running reference drivers? That's probably why it doesn't work. Install the latest ASUS drivers from ftp.asuscom.de and try them.

If that doesn't work, send me an e-mail and I'll send you the 21.81a ASUS drivers and WDM 1.04.

Hi

I had the same problem a while back and it drove me nuts trying to find a cure. I'm using a Zoltrix TV genie on a KT7-raid. the raid headers are being used but not the raid setup.

When I had the problem I even went out and got a 7200rpm drive to see if that was it. It helped, but still droping frames. what finally did it for me was on a re-install of the os, removed all the cards and installed them one card at a time with it's drivers. By making sure the tv card was "ON IT'S OWN IRQ" It finally guaranteed capture with no frame drops. ( test to at least to 640x480)

Thats my sugestion, it worked for me and now using Avi_io or virtual dub, they both work fine but avi-io has channels,,, no frame drops.

Good luck

[ILJR]

thx all for trying to help, although none of it worked.

As i already said, my final solution would be an Win2k reinstall.

I did that, now capturing at 702x576 with huffyuv, dropping 4 frames in 20 minutes (which is acceptable compared with 200 frames in 1 minute).

Still don't know what the Problem was. *sigh*

[Rich927]

Just a thought. It might have been a resource problem. Your reinstall may have cleared up the problem.
