While it wasn't designed for consumer formats like VHS, in conjunction with an ES10/15 as passthrough it's a pretty solid set up.

cbehr91 ok

Here is some capture with 704x576 on Ati9000 and i did a Test on a Test Pattern for 1.33:1 that i did find and i did capture it in 704x576 and 720x576 with ati all in wonder 9000 and it look that itīs best to capture in 720x576 with ati9000

i did use Ati9000 and Datavideo TBC-5000

Panasonic NV-HS930 = Internal TBC On & 3D DNR On Sharpen

one more thing i did a capture with Matrox Marvel G400 tv but the capture is more interlaced than the capture with ati 9000

on the ati9000 i see only interlace lines on the sweden subtitle but not on the titanic movie vhs

but on the Matrox marvel capture i see everywhere interlace lines

but on some other vhs capture it was the opposite the ati9000 did have interlaced lines but not the matrox
but mediainfo do say they are interlaced

here is Matrox Marvel G400 tv capture pictures

hmm here i test my Blackmagic intensity shuttle usb 3.0 and my DVDO iScanDuo
i did use VirtualDub to capture not Blackmagic Media Express

when i did use DVDO iScanDuo i did then use HDMI in 576P on Blackmagic intensity shuttle usb 3.0
when i did not use DVDO iScanDuo i did use S-Video in 576i on Blackmagic intensity shuttle usb 3.0

Test1
HS930>TBC5000>DVDO iScanDuo>Blackmagic intensity shuttle

Test2
HS930>TBC5000>Blackmagic intensity shuttle

The DVDO iScanDuo appears to add noise and reduce image resolution with that setup.

i did get a ATI Tv Wonder USB 2.0 it works very good on WinXP SP2

i did use this driver cd 180-V01100-200 it have driver version 6.14.10.6317 and MMC 9.08

but the driver version 6.14.10.6317 capture did look more interlace like my matrox g400 marvel capture

but i did find driver version 6.14.10.6314 and now i do not see any interlace lines on the Titanic vhs capture like with my ATI all in wonder 9000 and ATI TV Wonder 600 USB

and i did some testing S-video VS Composite and it looks like i maybe get better quality with Composite

so here is some pictures of driver 6.14.10.6317 VS 6.14.10.6314 and S-video VS Composite

The S-Video screencaps show some weird banding. That's not normal.

Looks like the fields 6.14.10.6317 captures are out of phase compared to the other setups, no idea what could cause that.

The TV wonder seems to crop more of the the left and less of the right.

The banding looks a bit like hannover bars, maybe the cards handle the chroma decoding a bit differently, it could be something else though. Won't be as noticeable on composite as the comb filter may cancel out the effect a bit more.

hodgey ok but 6.14.10.6317 works good on other vhs tape that have interlace lines like with 6.14.10.6314 and my ati all in wonder 9000 and ATI TV Wonder 600 USB and i do have ati all in wonder 9200 256mb but itīs the same as my 9000 64mb

on does vhs tapes 6.14.10.6317 looks progressive no interlace lines

but i think 6.14.10.6314 is the right way maybe to capture because it works then the same as my other capture card exept matrox g400 marvel

maybe it does something to do with Pal 25fps and Film 24 fps


i did find 6.14.10.6321 but it was the same as 6.14.10.6317

Regarding the "interlacing" (really phase-shifted progressive 25 fps). The 6317 has an extra pure-black line at the top, which reverses the field order.

the clips is with Composite HS930>TBC5000>ATI TV WONDER USB 2.0

Thanks for the lossless video samples. They take a lot of guesswork out of it, compared to screenshots.

It would be better to test with a full-frame tape instead of letterboxed, as then you would immediately see the black lines being added to certain captures. In fact, there are 3 lines "added" to the top of the 6317. (Any odd number of lines would reverse the field order, and only 1 of these lines is pure black.)

It's a lot easier to work with fields in Avisynth than VirtualDub. Field Swap is definitely the wrong filter to use.

I decided that it was easier to show what I'm talking about by making a little screen capture video rather than trying to type up a long explanation with a bunch of attached screenshots. No audio though. In the video, I demonstrate using Avisynth viewed via AvsPmod to match the 6317 capture to the 6314 one.

https://youtu.be/BQZKRtI3x2M (view at 1080p)

There is a diagonal interference pattern in these composite captures. It isn't visible when looked at in weaved "frame" mode, because it changes between fields, and looking at the 50Hz video as 25fps frames is effectively a 50% temporal average. I demonstrate it from about the middle of the video until the end, but YouTube's compression smoothed it over a lot so it isn't as noticeable.

These are the Avisynth scripts I used. Lines that begin with # are "comments" that are ignored when the script is read. An Avisynth filter line can be "commented-out" so that it is ignored. I toggle these commented-out lines with AvsPmod's ALT+Q command in the video. They begin with #~ specifically.
Code:
AVISource("HS930_Sharpen_720x576_TvWonderUSB2.0_Composite_TBC5000_Driver_6.14.10.6314_.avi")

#~ AssumeBFF().SeparateFields() # To compare fields to 6317 capture.

# Cut 1st frame (2 fields) to match length of "fixed" 6317 capture.
Trim(1,0)
Code:
AVISource("HS930_Sharpen_720x576_TvWonderUSB2.0_Composite_TBC5000_Driver_6.14.10.6317_.avi")

AssumeTFF().SeparateFields()

# This capture starts one field later than 6314 capture, because of the different field order.

Trim(1,0) # Trim one field from start: this changes the temporal field order from TFF to BFF.
Weave()

# Match spatial alignment to 6314 capture.
Crop(0,3,0,0).AddBorders(0,0,0,3)

#~ AssumeBFF().SeparateFields() # Double-check that AssumeBFF matches 6314 capture.
