Check out my first TV capture, any suggestions?

I'm using an ATI Tv Wonder VE with the drivers off sourceforge so I can cap any resolution. I get funny lines though, like it might be an interlacing problem? I used Huffy, capped at 480x360, 24 bit. Capping straight to 480x480 gives me funky wavy lines. Any ideas to improve what I've got? Thanks!!!

Do the lines come up during capture, or playback? The reason I am asking is when I play your video on PowerDVD, I see none of the lines you were referring to. A very good capture in my opinion.

See the edge of his shirt? It's like it doesn't stay solid, but clips or something. I watched it in WinDVD and didn't see a difference. And yah, I'm talking about viewing.

Use ATI's MMC 7.6 and capture to MPEG 2 740 by 480 I-frame only 15 Mbps non-interlaced (that the magic) use any encoder that reencodes Mpeg 2 such as flask, tmpegenc, cce, xmpeg etc ......... to create your intended final product. Interlaced playback on Computers and projectors sux!!!!!

Ok, I've tried another. (I'm using vdub to capture by the way). This time I did 720x480 resolution, no special deinterlacing or anything. Converted to tmpg, tried both interlaced and deinterlaced source, but didn't seem to do anything. This looks pretty good on my tv. Set bitrate to about 2000 so it wasn't cheating with a realllly high one.

It still looks funny on the computer, and while I don't care as long as it looks good on the TV, is there something I should be doing to deinterlace in virtualdub? I tried a couple filters but it didn't seem to do anything. Thanks again guys. Check out the new one:

I'm retarded...I think I was using the filters wrong. Right now I'm playing with capturing the film...then exiting capturing mode, adding the filtering, saving the new avi....and then converting to svcd and burning. I'll let you know how things go.

[nathan118]

hahaha, i've gotten bored of tv capturing and have gone on to capturing old home videos. I can now deinterlace with the best of them. Woot woot!

nathan,
the capture are great.... where do you get those drivers...
can i have the website to get the drivers that can cap with any resoultion or you kindly post in here so I could download from you
thanks

Deinterlacing With VirtualDub:

VirtualDub Filtering:
1. Smart Deinterlace: field only differencing, use cubic for interpolation, leave the rest in default
2. Blur
3. Sharpen: 60-64

Encode mode: Progressive (non-interlaced) (for SVCDs/CVDs/DVDs only)


Video Comment: Nice clip for a 15 year old tape. What was the person on the left going to say? She started with "are all these things ..."

hello all.

nathan118,
Interesting CAM sample. When I do DV cam footage, I use SmartDeinterlace v2.6
on it, but just the defaults, and as bbb stated above,
Field only differencing and I get pretty terrific looking results w/out any
blocks, even at Standard VCD resolution of 352x240. Again, from home=made DV cam
footage. I'm always excited of the quaity when I encode home-made footage from DV.

My recommend would be to turn off Digital Zoom and just use your camcorders'
Optic LENS, whatever the maximum is, at least for indoors footage. Outdoors is
another issue but indoor shows the best quality when using ONLY your opiticle LENS
and no digital zooming what-so-ever. Cause, when you pan left and right (we mostly
pan very fast, don't we?) the quality of the encoded video is still smooth and
blockless. Of course, I'm speaking of my Canon ZR-10 DV cam but I'm sure this goes
for ALL camcorders.

bbb,
I use the SmartDeinterlace v2.6 too, but you list struck a silimar tune.
My list goes something like this for VirtualDub v1.49:
* Smart Deinterlace v2.6 w/ [x] Field Only Differencing
* box blur (set to 1,1)
* Sharpen: 60

The only thing that through me off was your use cubic for interpolation statement.
I'll assume this is in another Version of SmartDeinterlace. I'm using Version 2.6,
so that's probably why that functions' not in my version. But, in any case, the
quality is very good for Standard VCD 1150 bitrate usage from DV footage. And, since
the DVD player I encode these clips for are only capable of laying Standard VCD w/out
issues, this is the route I use. But, it's interesting how your list nearly matched
mine. Well, actually, I do a little more tinkering around, but it approx the same as
mine. I also play w/ the above list for MPEG-2 (SVCD and CVD) test projects when I'm
messing around a bit. But, that's me. Always messing around w/ what ifs'
On my 15" monitor and at fullscreen, you still can't see any serious blocks though.
Of course you're free to try the above and see if its fair in your encoding projects.

I've ben meaning to post a home-made DV footage, but am just waiting for the right
footage to post.

Interesting, thanks for the tips guys. As for what that person was going to say...my mom by the way....I dunno, just talking about my sisters stupid toy.

I'm actually thinking about trying to turn this into a business. I'm leaning towards buying the canopus AVDC-100. The home video was shot on vhs-c, so I'm using an adaptor in my vcr. Plan on getting the canopus box, and then pluging the vcr into that. I should get a much better capture since it's all being done in the box, and then my computer is getting a digital feed via firewire right? This is too much fun.

Oh, by the way. That last cap, test.mpg, that was before I had saturation and gamma levels set to auto in virtual dub. That made a huge difference. My main bottleneck now is my crappy 25 dollar tv card.
