What can I say, Berni, you da man! :-) After messing around with lots of combinations today, I finally found that my so-called high quality LaserDisc looked a lot better if denoised (but not sharpened) and with a q value of 8. I left the bit rate alone, though. Sheesh, it's gonna take me a long time to get good at this. I hope I don't annoy the crap out of everyone meanwhile. :-) Oh, and I finally posted a patch to the mjpegtools web site. Now yuv2lav can do the audio at the same time it does the video. I also posted the script I use to record. My next patch, also to yuv2lav, will allow for A/V synchronization, by either adding or removing a frame every so often. Since my sound chip is separate from my video card, the sampling rates are slightly off, but I found the error is constant and repeatable. I discovered, by doing long recordings and then hand-adjusting the A/V sync near the end, that I need to delete every 30,500th video frame in order to fix the problem. Actually, I don't delete a frame, I just blend 2 frames together and output 1. Also, I don't do frame 30500, 61000, 91500, etc., but instead 15250, 45750, 76250, etc. That way, the average A/V sync error stays less than 1/2 a frame. This allows me to produce some pretty high-quality recordings with my cheap hardware, which is something I think Linux should support as well as possible. I'd post the patch, but it doesn't yet allow one to _add_ a frame if that's what you need to fix the A/V sync, and it's kinda hacked up. I want to rewrite yuv2lav to be multi-threaded, so there's a reader thread, a writer thread, and one or more encoding threads; that'll allow arbitrary frame insertion/deletion without mucking up the architecture, and allow for better performance. Is anyone but me interested in this feature? If so, I'll get off my dead butt & write it. :-) Steven Boswell [EMAIL PROTECTED] ------------------------------------------------------- This SF.NET email is sponsored by: FREE SSL Guide from Thawte are you planning your Web Server Security?
