VirtualVCR audio synch problems.....

[kenmo]

I can't seem to get audio and video in synch with this program. In the
settings for A/V Sync I have Resample Audio checked and Resample audio
dynamicly to 100.00%. Synch using streams offset is selected and
master Stream is Audio.

I'm capturig 640x480 YUY2 at 29.97 frame rate and it is uncompressed.
Audio is 16/44.1kHz stereo.

My system is an Athlon XP 1800+, 512megs of pc133 dimms. I have 4
ATA-100 hard drives configured as one logical drive. And I have a
dedicated drive for the os (Windows 2000 Sp3). My capture card is an
ATI TV Wonder. I am capturing vhs video thru rca cables. Main video is
a Voodoo3 and I'm using onboard sound card AC97 on a MSI K7T Turbo2
motherboard.

The speech seems too fast for the video ie: someone's mouth will be
moving before the audio begins but by the time the persons mouth is
still the audio has completed and appears to be in synch. This is
regardless if the person is speaking for 2 seconds or 45 seconds.

I've tried VirtualDub but I get more frame drops then frames captured,
MGI VideoWave 5 (seems to work the best but reportsmost frames
dropped), VirtualVCR and FreeVCR.

Stuff captured in VirtualVCR report frame drops but when I take the
file into VirtualDub no drops are report (confussing ???)

I'm thinking of either getting a Canopus AVDC or a capture card that
also does sound (not thru the sound card) or abandoning this hobby
altogether.

My source vhs tapes are new Maxell and Memorex. What gives ???? Any
thoughts would be much appreciated.

Using VirtualVCR v2.5.9 and apturing at 480x480 using Resample Audio and Resample Dynamicly 100%, Huffyuv v2.1.1 & preview disabled I was able to twice record two avi's for an hour that both had audio in synch and with frames drops of 5 for the first capture and 4 for the 2nd.

I am quite pleased with the results and with VirtualVCR !

Next I will try the same settings but will change resolution to 640x480.
I'm currious if it was the reduced resolution or the compression that kept the audio in synch.

Previously I captured 640x480 uncompressed and had audio probs and a file size of 60gbs. Using 480x480 compressed the fize size was 18gbs !

I use "sync using stream offset"

I have recorded three times an hour of vhs captures using the settings previously mentioned and all three times the audio has remained in synch.

This is one great little app...
