Then it wasn't mine.
Then it wasn't mine.
I sold my ATI 550 PCI this April on eBay. I now wonder if I sold it to you (Fremont, CA) :)
Cool. I guess whatever I captured via S-Video into VC500 can qualify to be your software's client.
I was wondering if anyone would like to check the 3 versions of a live gig that I did from LD. ATI 750 PCIe, DMR-ES24 to Blackmagic Design and S-Video to VC-500. All from Pioneer Elite LD-S2. These were not test pattern, but the real footage. Each m2v file is about 4Gb.
There's no driver by Diamond. This particulare driver is by AMD. On the Diamond website there's a link to the driver of AMD.
Also AFAIK the AGC problem is in hardware, not in driver.
Last but not least 750 PCI-e's comb filter is not that great for LaserDiscs.

The problem is that Blackmagic Intensity Shuttle for Thunderbolt drops (or should I say skips) the frames at random without informing the end user. If it doesn't report dropped (skipped) frames, how would anyone know that the frames dropped? Of course there's no way.
I will have to probably take it back regarding Blackmagic Intensity Shuttle. Most likely it was Panasonic DMR-ES25 that wouldn't process all the frames and would skip frames randomly. I used Panasonic DMR-ES25 as a middleman between my LD player's composite output and Blackmagic Intensity shuttle device. Recently I put Panasonic DMR-ES25 in between my VCR and LifeView FlyVideo 3000FM capture card and noticed a few skipped frames.
I will dig further and report what I will have found.
It has sharpness, but it makes things worse (ringing). Also I try not to use VirtualDub with this device because it doesn't have access to Philips native registry. I use this:

Here I get manual gain level.
PM me. I may consider lending the card to you.
3d comb filter is good. But for some reason overall image is blurrier. I can't explain why. I can test for you while it's still in my computer. I plan on taking it out.
I bought it in 2004. I think it is this one. http://www.comprousa.com/en/product/vmtvm800-hardware.html
But why would you want it?
When I unchecked stop capture if dropped frames are detected, that was even worse. Now I lost 8 frames in one hour of video. I plan on returning the device and get the extreme version instead.
Hi,
I have 15" MacBookPro with 500Gb SSD. I did test capture with HD 1080i as well as 720p. My HD can handle it. I also have the setting to stop capture if dropped frame is detected.
I will however try to set it to insert a blank frame.
But my question to you is, are you certain that your BM doesn't drop the frame? If I weren't doing simultaneous capture, I wouldn't be able to find this out. I suggest you do the capture with BM and either at the same time or after that do the same with "proven technology" (i.e. VirtualDub). See if you got skipped frame.
As for S-Video, I tried both DVP 649 DVD player and LD-S2 Pioneer Elite LaserDisc player. I didn't like the results at all. Diamond VC500 gave much better results.
Another thing is that Intensity Shuttle might indeed be different from Pro or Extreme.

I owe Blackmagic Intensity Shuttle for Thunderbolt. I am sure that the chip/hardware is the same as that on Pro and Extreme.
The problem is that Blackmagic Intensity Shuttle for Thunderbolt drops (or should I say skips) the frames at random without informing the end user. If it doesn't report dropped (skipped) frames, how would anyone know that the frames dropped? Of course there's no way.
But because I am doing simultaneous capture from my LD player to BM via Composite in to DMR-ES25 (Component out to BM) and the 2nd capture to VC500 via S-Video out, I can compare the end results. Out of 5 such simultaneous captures for an hour video, one time everything matched, 3 times BM lost 4 frames and 1 time BM lost 2 frames.
After that I also captured using ATI 750 HD PCIe. The end result matched with VC500.
In addition while BM gives very descent quality using Component inputs, the capture using S-Video plain sucks. For a product that costs roughly $230 vs VC500 $25 or something - this is unacceptable.
I can encode the capture into mpeg 2 and post it here. In a mean time I can tell you that it was LD VE, but I wouldn't say a torture-test. If you remember VE LD, they show how someone is trying to fix his home equipment with a screw driver and has achieved shortage doing it - everything goes white and then the next scene shows a house at night. So during the dark scene it would take a few frames to adjust the darker scene: it goes bright then darker, darker darker, back to normal. So it was not a test pattern but rather a real footage.
I tested LD Video Essentials with bunch of cards including ATI 750 HD PCIe.
Other devices I have used:
Compro VideoMate TV Ultra, ATI 550 Theater PCI, Panasonic DMR-ES25 as path-through to ATI 600 USB and ATI 750 HD PCIe.
I have used Pioneer Elite LD-S2.
Unfortunately ATI 750 HD PCIe triggered AGC problem. This same problem was triggered also by ATI 750 HD USB when I used S-Video out from LD-S2.
As far as comb filter goes 750 performed the best from DVD test captures. However, on LD VE capture it didn't do as good job perhaps due to the LD noise. IMO, the best comb filter for LD capture was NEC D64083 which is inside Compro VideoMate TV Ultra. However, the entire image is much blurrier than that on ATI cards. I can post images and/or mpeg samples later.

I'll be testing the Hauppauge HVR-2250 (NXP SAA7164 chipset) over the weekend.
I plan to capture the Snell & Wilcox Zone Plate, that pattern we settled on for AGC testing, and the Stormtroopers-looking-for-Leia clip.
Have you tested HVR-2250? How is 3d comb filter and is there any AGC issues?
Just installed ATI Wonder 750 HD PCIe. Here is the test result from Digital Video Essentials DVD via Composite in. All proc amp settings are default. Captured into Huffyuv AVI and then encoded with TMPGEnc. File 750pcieDVEmotionComposite.m2v will be available for 2 weeks from the following download location: http://we.tl/8EGNiAas2G

Also, the ES10/ES15 is the best 3D comb filter I've ever seen for NTSC material. I don't know how well it does on PAL material, however.
So is ES25 (US model) the same as ES10 or not?
_,,,^..^,,,_ said:
Take a look at this post, second image: as my ES15 have the same chipset of the ES10, it seems its comb filter has very low quality...
I should find a new capture card! Or, find the way to let the phase-inversion trick to work...
AFAIK, my LD-S2 also recombines Y/C signal, but I haven't noticed anything like that. I haven't posted it here, but still.
I have 6 capture cards with motion adaptive 3d comb filters. Here are the screen shots of 4 of them. I just got ATI TV Wonder HD 750 PCI-e, but I haven't opened it. Also I haven't bothered with Canopus ADVC-300 since it's DV only.
The test is from DVD Digital Video Essential test motion pattern of Snell & Wilcox.
1. Compro VideoMate Ultra capture card. This was the 1st TV Tuner ever made that incorporated motion adaptive 3d comb filter. It's Philips SAA713x based. But comb filter is by NEC D64083.
I think this card has amazing 3d comb filter. There are 3 modes: 2d + noise reduction, 2d + 3d and pure 3d. 2d + 3d is 3d but when it detects motion, it goes to 2d. But overall something is not right with horizontal bars (grey-black instead of white-black) and the fact that the image is a bit blurry. Anyone else noticed it? Other than this is the only card with 3d comb filter that has manual gain control which can be adjusted.

I don't like this card 'cause it has AGC problems. It blows up whites a little bit as well as black level.
ATI TV Wonder 650 HD USB
The AGC issue is insane on this card. However, for some reasons it didn't show any issues with DVE DVD. Maybe because I use drivers from VisionTek rather than from AMD? I don't know.

ATI TV Wonder 750 HD USB
Contrary to the claims that this card doesn't have motion adaptive 3d comb filter, you are wrong. It does. However, it's very weak and settings are not really adjustable. Yes you can adjust them in the Filter settings but the adjustments just don't take effect. This motion adaptive 3d comb filter eliminates dot crawl. It reduces rainbows, but doesn't fully eliminates them.

ATI TV Wonder 750 HD PCI-e - need to install it on my friend's computer and test it. My computer is old and doesn't have PCI-e slot.
To the previous poster _,,,^..^,,,_. Something is not right with your screenshots. How come that for the last Snell & Wilcox picture all screenshots have rainbows and dot crawls. Are you sure you didn't by mistake capture directly using S-Video from the LD player thinking that you routed via the DVD Recorders?
