[stanwebber]

this might be of interest to anyone wanting to improve upon their dropped-frame ratio. details at my website: http://www.geocities.com/stanwebber/

Why did you have to post in multiple forums? Now I can't visit your site.

i still have a number of these soundcards left & they are destined for the garage sale unless they sell quickly. all prices include domestic usps first-class shipping(international postage varies)

"...Recently i acquired a box full of old soundcards and spent some time testing them for clock stability in multimedia center. Most ended up being throw aside; however, to my surprise models with yamaha & ess chipsets tested consistently well. Naturally i am keeping the best performers for myself, but will sell the cards that tested in the slightly higher .03-.05 range to anyone interested in improving upon their dropped-frame ratio. at a bare minimum you can expect fewer than 1 dropped frame per 5000 from audio async alone..."

Tests performed using ATI MMC6.3 under Win98SE. Clock stability results presented in bold reflect the lowest/highest value returned after 11 consecutive tests following cold reboot (results are NOT averaged; first test-run is discarded)

It's really tough to find a sound card and a video card that "captures" at the exact same frequency. Generally the result is a 'drift' in a/v sync as the capture continues.

I would suggest finding a sound card that meets your capture card requirements. And then landing on a cutting/editing program that compensates for this divergence in capture frequency.

I should expand.....

A quick fix is to edit your file with (for examlpe) 10 minute cut and joins. This seems to fix many a/v sync problems.

It's not for me but it works. Pretty much a band-aide but it works.

Just find the right editing program. M2-edit works. It addresses the "drift" that is associated with the difference in frequiencies between sound and video capture appliances.
