Hello Guys.
i have a problem with my ATI All in Wonder card for tv-tuner capturing.
i try to capture tv-tuner movies on mpeg2 but i have a synchronisation problem between the video and the audio
sometimes, the audio is slightly delayed & sometimes is the reverse, it's the video which is delayed.
i have modify capture setting but the best i could do is to have one hour synchro and after that degenerate.
note:
i don't know if this can help you but this is my system:
Radeon All in Wonder 32Mo DDR
TB 1.4 FSB 266
SB Live!
IBM 60GXP
Asus A7v133
512Mo PC133
this is my setting from MCM 7.1 TV-capture.
maybe this can help you too.
- Capture High Resolution Stills
- PAL, 720x576
- 22Khz, 16Bits, Stereo for audio
- MPEG2
- Deinterlacing
- Visual Masking
- 3 P frames/group
- 2 B frames/subgroup
- Variable Video Rate of 10Mbit/sec
- Quality 90%
- algorithm search ranges 32H x 32V
with this setting i have a captured video almost as the video source from the TV.
but i have yet video/sound synchronization problems.
is someone knows this problem ?
thanks for your help.

Normaly this kind of problems are deu to broken signal.
The can be fixed using a Device calld TBC or by recording your material to DV first and capturing from DV.
the most simple way will probably capture in 1 hour or less parts.

Exactly
and you get audio and Video Sync problems.
Record your material to VHS and capture from it. You still might need a TBC or dubbing to DV to get reed of the sync problems.

I highly recommend that you use Windows 2000 or XP, then get 2 HD's (I recommend the Maxtor 40GB 7200RPM ATA133 drivers) then connect them to another 133 IDE controler. By doing this you can use Windows 2000 or XP to turn the 2 HDs into one using Dynamic Disk Management, this also turns the drivers into a RAID array, allowing less skipped frames and will help utilize less CPU resources.
Here are My computer Specs:
Tyan Trinity 400 Pentium 3 Motherboard
1 Ghz Pentium 133 Processor
512 MB of SD133 RAM
AIW Radeon AGP card
Soundblaster live 5.1 value
(1) Maxtor 30GB 7200 RPM HD
(2) Maxtor 40GB 7200 RPM HD
Promise ATA 133 IDE controler
Windows XP Professional
By the way, I am capturing with less than 1% frame loss at maximum settings, my CPU usage never goes beyound 65% used up. I also have any Antivisus Programs disabled as I am doing this process.
If it works for you then don't fix it.
