Question about USB device

[ezel]

I've seen a little device that plugs composite AV plugs and runs into a USB plug, runs about $75. My question is can you use this device to run a vcr into and be able to rip the video in good quality? dont know much about this so any help is appreciated.
Thanks

A name would be helpful

[negon]

sounds like a dazzle product to me, for so cheap it may not be worth the money.

May also be an ADS IDVD on sale. I saw one for under $100.00

....... can you use this device to run a vcr into and be able to rip the video in good quality?

USB 1.0 DON'T waste your time

USB 2.0 maybe --- usb2.0 = 480Mbps (megabits per second) = 480/8 = a theoritical 60 MByte/sec or ATA 66 harddrive speeds. I would expect you would get no more than 40 MB/sec in the real world usage.

USB 1.0 DON'T waste your time

-- I respectfully disagree. My ADS IDVD is USB 1.0 and it captures in MPEG-2 720 x 480. No problems here. If it could convert analog to DV, I would never upgrade.

I respectfully disagree to your disagreement ......

USB 1.1 spec (Up to 12Mbps) divide that by 8 and you get 1.5 Mbyte second. Hardly capable of decent data through put. Consider the VCD spec is 1.15 Mbyte for video.

Capturing in MPEG2, as you state, the best you can expect from USB1.1 is 1.5Mb/sec .. Uggg a poor bitrate at that !

Remember: It does not capture at that rate. The encoder only transfers its files to your computer at that rate. It is capable of capturing up to 5MBps. The throughput is what the encoder transfers the file to the computer AFTER it has finished capturing.

No, it's realtime (if we're talking about the original ADS IDVD). Top bitrate is 6Mb/s MPEG2. Now, that's not TOO bad for DVD MPEG2, since it'll put 2 hrs on a DVD blank at not bad quality. Not as good as TMPGEnc at 8 Mb/s, but not bad. It's all about convenience anyway, for a device like this. The REAL problem is audio/video sync, since audio is capped by the onboard sound of your PC/laptop.

The new version is USB2, and (more importantly, IMO) encodes audio as well to solve some sync issues. But there have been problems.

Funny, I do not seem to have all these problems you claim I should have. I do not have any synch problems dropped frames, etc. It works as advertised. Maybe mine is broken?

Actually, I don't have those problems, either. But they ARE rampant in the forums I've been in concerning the product. I DO have a prblem with the audio. It seems the software limits the audio bandwidth to 10k or so. Not bad for camcorder transfers, but for other sources, not so good.

Glad yours works great. It was still the best I've seen when I chose it over the similar Hauppauge device (that I returned) and the other ones I didn't bother to order. But I haven't tried the new version, nor the Snazzi III. And it's still not as good as a few PCI devices.

At <$100, though, it would be a great deal for someone who can live with the limitations (mine was $150-ish), as long as they have return priveleges in case it doesn't get along with their system.
