I agree with you, iuVCR is by far the best capturing prog I've used so far, with my Asus V8200 deluxe.
CPU usage is so low, I can even crop video in real-time.
This comes (I think) from a very good WDM interface; which is obviously better than vfw.
All you need is a good WDM driver for your video card ...
iuVCR is good but for my slow p3 i get too many dropped frames. I like the way the program steals audio resources from other programs. The only thing about it is that i cant get the audio and video to be in synch no matter how many different options i mess around with. Right now for my computer i prefer avi_io_trial for video capture with DivX4.12 as it has given me almost perfect captures, it also comes with a scheduler.
I am using iuVCR as well but I am quite confused with the frame rate I get. It's programmed for 25 fps but the result is an average of 24.7 fps. What confuses me is that there are 0 frame drops ! How can this be ?
Any idea on this ?

@ phrentec i have the same prob when leaving the audio-stream in original pcm! encoding to mp3 solves the sync problems... (dont ask me why)
Yes. FLYCAP it is. And lighter on demands over
your system. And: it is Freeware.
@ Milos did the corp filter come with iuvcr??? or u installed it saperately... can i know where can i get the same

I still prefer vdub with a/v sync mod with both vfw and wdm drivers (you need the wrapper for wdm.) iuvcr was too buggy on my system and there are better programs out there that can capture just as well or better for free. Virtualvcr is another good one with wdm drivers.
VirtulVCR performs slightly better here then iuVCR
i love iuVCR but frames are like 24.72 etc
but Virtual VCR gets it up to 24.99xxxx
but still with both proggies i get the video racing ahead of the aduio to wheres its over a second ahead after bout 45 mins
Video: mjpeg @ 19
Audio: PCM @ 44100hz, 16, stereo
i'll try komaklar idea to compress the Audio, see what happens
(if it works, that sux ya cant cap in uncompressed)
VirtualDub Sync works best for me. My system is PIII/1GHz, NVIDIA graphic, TerraTVValue, capture in half PAL to DivX5.02
yeah i never had a sync problem with that
problem now is that i have a CX23881 based card and want to cap @ larger then 320x240 res
i found a solution for everyone
forum/viewtop...=425910#425910anyone know what VD does different to other cap programs to keep sync so well ???
I've never had sync problems with IUVCR. I usually cap in MJPEG at 90% or 95%(Morgan MJPEG is a fine product, worth the $$$), and PCM audio. 1 hour cap and it's synced at the end, zero dropped frames at 640x480. Athlon 2000 and a 100 GB drive with 8 MB cache helps.
I don't like it's scheduler, it's not friendly to setting up weekly timed recordings. It does tend to drop frames the first 10 seconds on timed recording, but so what, I always start 1 minute early. It doesn't like to pause and resume either. PowerVCR sucks because it's MPEG only, but it's really nice about timed captures.
hmmm changing the frame rate through VD doesnt always work
i capped a file from my Camcorder (8mm tapes) and ran it through (intially saying Video was @ 25.000 and Audio @ 24.826) but even after syncing them the Video was still a bit ahead after half way through.
so tried setting the frame rate to 24.800 and that was too much compensation,
so trying now @ 24.820
but why this is happening i have no idea,
yet to try Audio compression
i never had this trouble before when using a BT878 and VD and capping @ 352x288
this sux!
one think though, now using Virtual VCR, i can cap and do many other things with a single frame drop
hahhaha, but now i need frames to be droped
(to keep sync)
I like iuVCR and use it alot, but I also use AVI_IO and recommend people to try it out to.
hmm i have tried AVI_IO but it either crashes on me @ low Res and hi res it wont capture
i am very happy with Virtual VCR anyway
The best capture apps are VirtualVCR (WDM) or VirtualDub Mod (VfW), with the universal BTWinCap drivers. These are the only capture apps that maintain AV sync by resampeling the audio, not duping/dropping frames (yuck!) And the BTWinCap universal drivers are much more compatible than the iulabs universal drivers.

cool,
i still got sync problems with Virtual VCR
but i used a copy i had on my HDD (ver2.3 build 2301 or something )
so downloaded the lastest and will try that
i notice alot of sync fixes in th change log

I don't know what to tell you poor guys. Some rare people, continue to have the sync problems. My fisrt instinct would be that they have VVCR configured incorrectly. But, I'm sure this is *not* the case, for many having problems.

you dont have sync problems ???
can you post yuor exact settings here for us ??
so we can compare
and maybe a cable configuration too
much appreciated Originally posted by DaveQB

Not a one
I just upgraded to the latest version. Here are my settings:
Settings - AV Sync Tab - Check *only* quot;Resample Audioquot; and select quot;Resample Audio Dynamicallyquot;. |
