Quality Video Capture/Editing

by dleskie / June 2, 2005 2:39 PM PDT

I currently have a Pentium 3 - 500 MHz with an ATI All In Wonder (32mb ?). The capture from the TV cable is choppy at high resolution (I'm pretty sure it's from the capture, not the playback).
I am upgrading to a Dell computer 3.0 GHz and am wondering if the new All In Wonder cards are the way to go. A quick search of this forum suggests using an external capture device with USB 2.0.
Should I just get a cheap video card with the Dell and get an external capture device, or should I upgrade the Dell card? Will an external capture device have a TV tuner or would I have to buy a seperate card for that? Will this allow me to capture from VHS and TV without the choppiness I have now? Sorry for all the questions, any help is greatly appreciated.

Analog video is... not quality.
by R. Proffitt Forum moderator / June 2, 2005 10:03 PM PDT

This is the first complaint from those just diving into this area. NTSC or PAL is all of 480 lines or less and the first scream is not unlike your post.

The P3-500 is a little on the low end for analog capture which would stress most to tweak it to work. I'll just say it shouldn't work for most and be choppy.

I had the same configuration 5 years ago

when I bought my second PC. P3-450 with All in Wonder (1st generation), it was a 32MB card.

Video captured to it WAS choppy.

The problem, as I was told, was at the video card level, which is the first place the process can bottleneck. It wasn't able to process enough to get you near the 30 fps at any decent resolution. I tweaked the settings to lower the color depth and resolution. It looked so back it wasn't worth it.

If you do upgrade the video card, be aware that once you overcome this obstacle, the next problem you'll find may be memory and the front side bus of that chip, which is probably only 100-133MHz MAX. Then the hard drive buffer if the one that's in there even has one.

The only way the process will run smoothly on the PC you've got is to produce a capture that looks like this quality mms://

which is a disappointment by today's standards.

There are other options and opinions, but I have read that ''firewire'' (IEEE-1394) is the most optimized connection for video, and beats USB 2. Now I cannot find that article but can find others that say ''it's a tie.''

I use firewire, and it has always given me smooth and flawless video capture.

I would guess that your present CPU is causing the choppiness. 500 MHz is right on the fringe for videowork.

Once you get your new machine I'm sure that any decent capture device will work with it, be it USB 2 or firewire. You'll have plenty of speed for video. Just make sure you'll also have plenty of room for it. If you want to capture analog/VHS and/or want something with a TV tuner, just make sure it does it before you buy.

One More Point

In reply to: Firewire

If you do want to capture VHS/analog, make sure you capture to uncompressed DV (DV-AVI) for the best quality and easiest-to-edit video.

I like to use seprate video and capture cars, USB or PCI.
Does the Dell your getting have onboard video?? A lot of them do.
If so get a stand alone capture/TV tuner card.
There are a lot of them out there From $50 to the ATI HDTV wonder for $150. If you live in an area with a lot of HDTV sations this might be a good chioce.
As others have said if your capturing video from DV camera the best way is to use firewire, since it was developed specifictly for video. John

The choppiness is because your machine is too slow.

As for capture on a new machine, if an external device is used, firewire is better than USB.

Try looking at a Hauppauge capture card which may work better than an AIW card.

PS: One key reason for the choppiness is that the CPU is

being used to encode the video. The Hauppauge cards have hardware encoders. You should not get a card which lacks the hardware encoder.
