ATI AIW filters?

[distendad]

Within the detailed capture settings the AIW 8500DV and MMC 8.9 has video soap, conbined 1 & 2, soft, sharp, etc. adjustable from 0 to 100. Unfortunately the ATI documentation provides no information. The various guides also record little about the filters. The filters could be better used if a user knew what and how they adjust video. Are the combined filters active on Black & white video? Has anyone researched the ATI filters?

The best source for AIW information I can think of is Lordsmurf (a member on this forum). He also has a web site (www.digitalfaq.com)

They left it out because it's a small issue, and few people need it. Search here or the net on the main term for each one and it shouldn't take 5 minutes to figure them out.

Heck just looked and really they're all obvious except the combo 1 and 2, and there is a preview to see if they'll help on something. What's your question? You turn them on and see what they'll do, fairly plain and simple.

I know those filters pretty well. What kind of error are you looking to correct? My guide for this is currently not up yet, but I'd be glad to suggest a few fitlers to you based on what I hear from you.

Best results use combo filter 1 and 2 at 75% but you need a very powerful system not to drop frames. For less powerful systems use combo filter 1 at 75% with sharpness at 25%. Try other settings yourself it's all very subjective.

Be careful with temporals on combo filters. I'm not always a fan. I tend to use 17% or 75% with custom filter sets for salt-n-pepper grain removal. This works much like TMPGENC noise filters.

I tried to use the preview window to observe the the combined filters, but do not see a difference between Zero and 100% combined filter #1 for either color or B&W video. The preview window is too small to observe any but major changes. The computer resources bar indicates Combined filter #2 overloads my PC at any setting. I have a 2.2 GHz P4 PC. Video soap ?

I am attempting to back up 10 to 25 year old B & W and color VHS movie tapes. I plan to retire my laser disks and VHS material. Some of the tapes are grainy, have lost color saturation, and may have reduced sync signal levels. My hardware string is JVC SR-V10U>SIMA SCC>FacetVideo Clarifier>ATI AIW 8500DV all S-video. I have no problem backing up the better VHS tapes. Understanding what the video soaps, and the combo filters 1 & 2 are designed to do on color and/or B&W video would lead to better usage.

Ummm .... make it bigger.
It does that.

Make preview bigger:




Drag it out. Make it full screen. I have 19" monitor, can make preview full 19" if needed. See changes fine. Can also alter left half, right half, top, bottom or full changes.

For grain removal only, use this settings here, 15% despeckle.

To alter colors and contrast, go into the VIDEO settings, not VideoSoap:



Combo filters tend to make images blurry or have temporal errors (ghosts and drags). But they can remove pretty bad noise, including herringbone and static.

I never use defaults since I started playing. Play around. Use the preview to look and compare.

My most common are 15% and 50% and 75% despeckles.

Thanks all especially Lordsmurf. My capture quality has improved by expanding the preview window and tuning the filters. Sharpness actually helped the most. Combo filters don't seem to be too useful.

I attempted this despecle, using dvd quality compression, and i am loosing half my frames...... i have a pretty decent system and i have been watching my cpu and its barely hitting 50% while running. is there a way to monitor the video cards processor speed? Can anyone tell me why i am having problems loosing so many frames?

the video comes out real choppy and i cant see much of a difference in the video soap despecle effect.

To bad there isnt a way i could despecle this after i have captured it, maybe i wouldnt loose frames that way......

by the way i use Ulead VideoStudio 7

Nightstalker, could be your hard drive speed. Try getting a faster drive and keep it defragged. Also try capturing to a drive other than your system drive, not just another partition.
