Vibration causing images to go wierd

[woodlander]

Really don't know what to call this, but when I convert from a VHS camera through a USB dongle, to windows movie maker, the resulting video will go weird whenever the cameraman took a step and vibrated the camera. If you don't know what I mean, I'll post a picture of it, but it does not appear on the original recording. It almost appears as if the film is physically lifting off the tape head and becoming warped etc.

Can anyone tell me what it is? I assume it's because of the deinteracing? The captured video is 25 fps instead of 50 fps interlaced, but the general smoothness is acceptable, it's just the jerking that's the problem. If the cameraman didn't shake the camera around, it doesn't even happen. Would it make a difference if I could record this at 50 fps instead of 25? Does anyone know of any capture software that doesn't automatically deinterlace? Thanks.

You need to post a short video sample. I suspect you just have the wrong field order.

It's hard to tell much from a youtube video. You should post a short sample of the original video, not reencoded, not deinterlaced, etc.

I did see frames like this:



Is that what you're talking about? That has been poorly deinterlaced and there's some kind of horizontal sync problem with the VCR or capture device.

Yes, in that frame is exactly the problem. If the camera is plugged into a TV (even an LCD) that doesn't even appear.

I am using a cheap and generic usb capture device similar to one of these:

These kinds of devices always do this?

EasyCaps don't always do exactly that. But they are among the worst capture devices out there. A decent capture device costs a couple hundred bucks USD, better ones are twice as much, really great ones run into 4 figures. What do you expect for ten bucks?

I expected pretty much what I got, minus the strange effect. Aside from when the camera got shaken, it was acceptable for my needs.

But yeah, I need something better. I knew this infact, my eyes rolled when my dad walked through the door with this dongle in his hand and asked me to back up all our families old home movies. But I don't need to spend thousands or anything. What would you suggest?

A Hauppuage card will probably work better and won't cost too much. Something like the HVR-1250 can be had for about US$65 and should do a better job.

If you want really good caps from VHS you need an S-VHS deck with a built in line TBC. Or you can try an external line TBC like those built into many DVD recorders.

If you don't plan on doing a lot of heavy filtering and editing you might as well skip the computer capture and just record onto DVD at the 1 hour setting. That will be a lot easier.

Thanks. Will that particular card work with PAL signal? It says NTSC in the specs (though I would imagine it's just a matter of software?). I'm seeing what seems like a comparatively cheap one here on ebay that might be suitable for me:

I don't plan on filtering and editing (probably would given the chance, but just want something half decent to start off with). But firstly I don't want these resulting video files on DVD. I've found DVD-R to be unreliable, I want these on a hard drive. Are you assuming that I have a DVD/VHS combo box? Because I don't have any such thing.

Anyway, thanks for the advice thus far.

I don't know if the HVR-1250 will work with PAL. If not, there's sure to be a PAL equivalent. The chips used on all these capture devices work with both NTSC and PAL. So it may just be a matter of drivers and software.

Regarding DVDs, you can copy the files off the DVDs onto your hard drive if that's what you want. A DVD recorder with a line TBC and full frame TBC will give you better results than any capture card capturing from a VHS deck without a line TBC. The only S-VHS decks (with line TBC) available now are used. And they're very hard to find in PAL areas.

The ATI 600 cards work with PAL.
AVI only in VirtualDub, but that's ideal anyway. Reencode to other formats as needed.

Thanks. Though it looks as if the ATI 600 USB will be a little difficult to get hold of.
