Hi there,
I encoded 2 clips from "Cast Away" and "U571"; each clip is about 3 minutes. I used 3 settings in encoding those 2 clips;

setting 1--original kvcd template but is 352x240; CQ=74
setting 2--original kvcd template without altering a single thing
setting 3--orginal kvcdx2 (704x480) without altering a single thing

OK, setting 2 is out of my consideration because I don't like its size; my standalone player may not be able to display it properly, it looks like that it squeezes from top and bottle.

Now, I really can't see any difference between settings 1 & 3; they are both looking good and sounds good. Setting 3 has a risk that it may not be able to fit into a single CD-R and it may take longer time to encode the whole movie. Can anyone give me a suggestion which setting I should use before I press the "start" button in TMpeg, I don't want to waste my valuable 10 hours. Thanks!

One last thing, I have to pump up the volume to 300% in "Audio" tap in TMpeg to reach a hearable level, is there a upper limit for audio before distortion appears?

Hi syk2c11:

If you look at an mpeg made with the KVCD and another made with the KVCDx2 in a HDTV or a high resolution TV, you'll see a huge difference.
In standard TV's, you can hardly tell the difference.
If setting #1 is good for you, go ahead and use it, because the file size will be the smallest and the encoding time will be the fastest.

For the audio, you should use some "Normalization" before it goes into TMPEG. I always use "Normalize" and "Dynamic range" set to "Normal" in DVD2AVI. Also TMPEG's max audio normalizartion is 400.

What I refer to is standard NTSC TV resolution.
In a regular tube type TV, you can barely see the difference from 352x480 to 704x480. Even if you have a large 36" TV.
That's because these resolutions are above the regular NTSC TV resolutions.

In a HDTV, you have a much higher resolution, and there you can see the difference.
I even see ( some times ) little blocks on DVD's on my HDTV!

In Europe there is no such thing as High Defination Television! Then again with a decent PAL signal the picture is so much better than NTSC the difference in quality wouldn't be as noticable. No, widescreen is the "in thing" here at the moment, although the UK's satellite service (Sky TV) doesn't support it at all ... apart from a part-time film channel. The BBC and ITV are really annoyed that the World Cup isn't being shot in widescreen. They had billed it as the Widescreen World Cup and had gotten manufacturers to plug w/s TV's over the last few months only to find that it's in 4:3 format and crappy NTSC to boot! Nice to see the Jubilee celebrations in widescreen. Captured the pop concert from Buck House last night in w/s, now just have to cut it down a bit and re-encode to CVD specs.
