VHS Capturing

[Bea]

Hi,
I want some of my old VHS onto a harddrive, so i bought a new Harddrive and took my laptop (an IBM a22p) and wierd it up.
I hooked the VHS up with my laptop, download VirtualDub and started ripping.

~1 hours later it was finished ripping and I had a file on 57 GB on my harddrive. Now i wanted to Compress it, so I downloaded XviD codec and started compressing. After alot of waiting, it was finiched, but my .avi is out of sync. So I looked at the uncompressed one and its also out of sync :S

Anyone have any suggestions what may be wrong? Is it my Laptop that is too slow? Should I use another Codec? Another Program?

Also to mention, when i ripped I did no compression on the sound.

Hope you guys can help me with whats wrong
Thanks in Advance

What codec (video/sound) are you using?

Codec may cause problem, but not using codec your filesize may rocket up to many gigabyte, download HuffYUV and install, it's quick and loseless.

For AVI container, don't use MP3 or OGG VBR, this is the easiest way to outsync, use CBR or change container to MKV.

I still capture sound in WAV because I didn't found any quick and loseless codec yet.

That hint about not using VBR is hogwash. VBR ogg and mp3 use per frame bitrates, that will have nothing to do with sync-issues.
I have never had any sync issues encoding to Ogg Vorbis or MP3 VBR audio under video.

Ive downloaded the HuffYUV and going to try that soon..
But I tried to do a test capture from a VHS, and the audio is out of sync on that one too, before i have done anything with it :S

Why is that? any suggestions?
Is it my computer that is too slow ?

Thanks

Avery Lee stated VBR cannot be used in AVI container, if you're talking about MKV of course it's OK.

Depends heavily on the hardware and software you're using.

My Canopus ADVC-1394 only can capture with Media Player Classic 6.4.8.4 (VFW) or buggy WinProducer 3 (I don't like it force me to capture with MPEG2), even VirtualDub's capture will mess-up. ADVC-1394 can did lipsync excellent, but the input level is very low, so I switched to my M-Audio Revolution 7.1 for audio capture.

Capture video and audio with different device, remember the audio should have delay, I capture with MPC, audio need to compensate 100ms delay.

And don't use stereo except your VHS already recorded with HIFI.

Hi again.
Ive been trying alot now and still have trouble.
I Tried to capture with MPC but when I enter "live" mode I only get a black screen and no Video :S
I also tried BSPlayer and got the same there :(

So It seems like I only get video in Virtual Dub.

Any ideas?
Other programs I should try?
Thanks in Advance

Hi,

Try VirtualVCR

good luck

That means MPC not working for your card.

If Virtual VCR not working, you need the original package with the card, usually is WinDVR or such thing.

If you get a blank screen and not an error, its actually a good thing. Your capture drivers appear to be working, just no signal. It's possible you're trying to capture from the wrong source. Might be a setting somewhere that you can change the source from svideo->composite->etc.

You really want to try using HuffYUV instead of uncompressed raw avi. It is possible that even HuffYUV isn't compressing enough on the fly. That could be your cpu not being powerful enough to process that much information in real time or your bottleneck may be the hard drive speed, being a laptop it is most likely 4200 to 5400 RPM. Since your hard drive can't write fast enough to store all the raw data input, your memory buffer will fill up and you'll start dropping frames.

As for the audio, as someone said, if you are capturing from a different device there will be a slight delay. Whatever you do don't try to play with frame rates while the video or audio is separated. You CAN try and re-sync them if you do that but its extremely complicated. It requires adjusting the pitch of the audio, and I can't remember details.

What FPS / Res are you encoding at?
