problem with recording help!!!!!!

2004-08-18 12:25:03 am

I love YaBB 1G - SP1!

i recently bought a dazzle digital video creator 80.
after i go through all the hell long installation and ready to record, but i found that the video capture window in the software is too damn small.
is there any way to work thing out to make the window bigger?

I asked google about the device and found this page: http://www.cwol.com/usb/dazzle-dvc-80.htm . There it says that the maximum capture resolution is 320 x 240 so I guess you're stuck. That's really low.

I would say that's the disadvantage of the low capacity USB interface. It simply can't transfer data fast enough to support higher resolutions. You'll need an internal device for that, or possibly an USB2 one, not sure.

I use 320x240 and i'm fine....
ntsc tv is only 240 some lines, so you're not getting any advantage by capturing higher except that you can restore the full 60fps... which of course is good, so my card is actually shit! :-/

Heres what you can do.

You can get a video splitter so you can feed video and audio to both your computer and a t.v. from the same console.

What you'll need.
-4-Way A/V Distribution Amplifier
-2 Standard Stereo Audio/Video Cables

How it works.
It splits the audio/video, like a cable splitter.

How'll you'll need to set it up
-You'll need a T.V. near you computer (About six feet depending on how long the A/V Cables are)
-Plug in each of the audio/video cabels to one of the output sockets
-Take one of the A/V, while pluged into the 4 way A/V Distributor, Cables and plug it into the computer
-Do the same with the other one, but plug it into your T.V.
-Take you console and plug the A/V cable into the input part of the A/V Distributor

Hope this helps.

First, I'm new here, so I want to say how much I've been enjoying this place, especially the Zelda runs.

Anyway, after downloading and enjoying the HQ versions of the AvP(Jaguar) videos, something ocurred to me: why 60fps? NTSC video runs at 30fps(technically 29.97, but whatever), so why expand it to 60? With AvP it struck me as a waste(most of the game runs at 10fps), so I downloaded part of the Castlevania: Lament run in HQ to see what it looked like and it actually was 60fps.

I still had to ask, though: why? The video doesn't run at 60 frames, but 60 fields(half a frame; every other line). I don't know if Nate's card actually captures like this, or if he does it afterward, but there's no point to it. In each of the 60 frames, every other line is a duplicate of the one before. In reality that degrades the picture quality(if you look closely you can see the lines are duplicated), as you never actually see a complete frame. To get the highest quality you should capture at 30fps and run the footage through a deinterlacer(most encoding apps have one) using a "blend fields" setting.

Before I run and hide, a few clarifications regarding video.

...

Or not. I just did a search to make sure I wasn't feeding you false info. An hour later, my head hurts and I realize they only taught me intermediate video at college. In reality, the whole NTSC thing is insanely complex, but here's what I know for sure: 525 lines of vertical resolution; depending on the hardware used to transmit, receive and capture this info, you'll see either 480 or 486 of them. VHS has 250 lines of resolution, though it certainly doesn't hurt to capture at full res.

Finally, Radix, your card seems to work just fine(Mega Man 2, Bubble Man stage notwithstanding). Thanks for letting me rant. Looking forward to the GTA3 video(after returning home for Christmas)...

That's what nate does. To recover the full 60fps you need to capture 30fps at 320x480 or 640x480, then seperate the frames into two frames (deinterlace) to end up with 320x240 or 640x240 which you'd resize either down or up depending on the game's original resolution. See super metroid where the game runs at 224 lines so there's no point going up to 480, but it most certainly does have 60 hz effects.

Of course, 60->59.94 and 30->29.97. Stupid ntsc!

Yeah my card is far better than some I've seen, but it randomly dropps 3-4 frames a second because there's just not enough space on the USB to send them all. It's also compressing the frames to send them on that, so even though I capture with a lossless codec, I've already lost stuff. And no 60hz for me.

Super Metroid is actually a good example. First, notice the screen alternating back and forth ever so slightly on each of the 60 frames(it's too regular to be a VHS problem). Second, watch the opening right before Ridley appears(Samus is shooting at the baby Metroid). Notice how in the 60fps version the shots disappear and reappear at irregular intervals. So, while it's true you can technically make 60 half-res frames from the individual fields, those fields were never meant to be seen seperately. I would use the 30fps version to prove my point, except Nate deinterlaced that one with the "Duplicate Field" method(you only see half the shots). If he had used the "Blend" or "Interpolate" method you'd see a "shadow" of the missing shots. This is what you'd see on videotape, albeit without the blending. Behold, the evils of interlaced video! Grin

Give the Blend/Interpolate method a try sometime. I'll admit the effect looks kind of odd when still-framed, but at full speed it's superior to Duplicate Field and vastly so to the faux-60fps method(and playback won't kill your CPU).

I hope I'm not stepping on your toes here. I just like working with video and right now about all I have to do is rip/encode seasons of various TV series' so they'll fit on one DVD. To make matters worse, I have this brand new capture card and no VCR to capture from. Angry
