Pertti,
If you've read the thread, you'll recall Dutchman started it with a G200 specific message and I mentioned I had a G200 in my second post.
Which of the three G200 marvel problems I sumarized doesn't affect the G400?
I don't use the "TVout", and stated that I was passing on the problem reports of others.
I don't think it would be hard to improve the G400 over the G200 here. Details please.
I'd like better nomenclature to use when refering to the composite video out of the BOB when playing back dmb1 codec AVIs vs enabling TV output in Powerdesk which for the G200 forces 60Hz refresh on NTSC. This is why I turned it off after enabling it briefly. I can use 60 Hz refresh without problems on many systems, but the Marvel's very high quality 2D seems to really emphasize the flicker on my particular monitor to the point it really bothers me. YMMV.
The G400 does have the black bar on top and left edge transcode problem based on a MPEG posted here when the G400 was new by someone with a GL-1. When I pointed it out, he called me stupid and said it was function of resizing for MPEG, when I called him on it, asking why going from 704x480 to 352x240 or 320x240 I should expect a black bar on the top and left edges, he never answered.
Fluggo,
I don't think you know what you are doing when it comes to VCD format. Your solution confines you to only plugin or codec MPEG encoders which either suck in quality or aren't available for MSPRO5.2 thereby forcing you to render twice, once for the clipping and resize and again for the MPEG (unless you have a plugin encoder, but my tests haven't found an acceptable quality plugin, Xing just doesn't cut it, Darim is total crap!). If you've infinite free time for rendering, good for you! We'll not mention the disk space required for rendering to uncompressed video and the 2G file limit, or the quality loss from recompression if you render to a different codec before MPEG encoding to save disk space.
MPEG1 and VCD has always been of "why bother" quality to me until about three weeks ago when K.S. posted a clip of Luke shooting the photo torpedo into the Deathstar on the rec.video.desktop newsgroup -- quality blew me away! Definitely worth bothering with.
Problem is, he captured uncompressed ~16MB/sec to a RAID array (with a cheap BT878 card!) and used that as input to the encoder. My tests are comming to the conclusion that the uncompressed capture must be the trick because there is not alot of difference between Ligos2.5, Panasonic, and AVI2MPEG encoders. Xing is barely acceptable and Darim is terrible. Needless to say, this method is full of practical problems when trying to produce a 60 minute VCD.
I'm comming to the conclusion that the dmb1 transcode problem is moot for VCD because even best quality MJPEG captures are not sutable source for MPEG1 encoding period.
I'd like to point out that any of the MPEG encoders I've mentioned "look good" in a dinky 352x240 window on a 1024x768 display, its playing back full screen that seperates the best from the rest. The best really are usable for timeshift recording. I've been skeptical of Tvio because the demos at Best Buy have only been talking heads on a clean background -- exactly the way to hide MPEG encoding defects. Someone else on rec.video.desktop, a real ATI ehthusiast, says the Ligos "GoMotion" real time MPEG encoder gives "VHS quality" with his AIW128. Perhaps, but I'll believe it when I see it, he has a web site, but I found no sample clips I could download.
--wally.
