Tmpegenc serious macroblock probs!

[davidian]

Hey. I am right now really pissed off. I've always used Tmpegenc for DVD-SVCD conversion. I converted X-men using CQ 2500 kbps and quality 65 which gave me excellent quality, no singe macroblock whatsoever.

BUT, now, I am trying to convert just one scene with a lot of movement from Terminator 2 (the scene where Sara's dreaming about her own death, when a nuclear bomb explodes and scatters her and a city, and some playing kids), just because I know this scene has a lot of movement, yeah.

Anyway, I tried the same settings as I've used before, and I get hell of a lot of macroblocks! The fastest action scenes in X-men didn't have ANY blocks and it was crystal clear, crisp and .. just excellent.

So I even tried raising the quality to 100 and used motion estimate blablabla highest quality, but that didn't work either. I even raised the bitrate up to 3000 kbps .. but there are still macroblocks. OK, not as much as before, but they're there, and I think it's really strange since X-men didn't have any at all, and there are many action scenes..

What am I doing wrong!?

try cce ..just encoded the whole movie in SVCD on two disks...and there is not a single macroblock to be seen anywhere...:d

What other programs do you need to get your ripped dvd ready for CCE?

[Truman]

decoder: dvd2avi
filter and frameserve: AVIsynth or VirtualDub
video encoder: cce
audio encoder: tooLAME
multiplex: bbMPEG

Let me add that you might want to try TMPGencs 2pass VBR at a high bitrate OR CCE's multipass VBR. Normally if I'm doing something in CCE I really like I'll set it to 3pass VBR. If you're only doing a short scence you can try 4pass (or what hell even 5pass )

[davidian]

Yeah I tried CCE, used 4-pass VBR and there were terribly much macroblocks..!
I was using 2.5 SP or something.. perhaps the latest version is better?

[Truman]

Latest version 2.62 isn't better, but it doesn't matter because v.2.50 is superb.
Something you are doing wrong, sure. You may post the details, maybe someone figure it out.

[davidian]

OK. Source is DVD - Terminator 2 special edition
It's 15 seconds, a scene where Sarah Connor is dreaming about the future, when she gets blown up by a nuclear bomb along with some playing kids.
That scene has lots of motion.

(clad DVD for ripping DVD)
DVD2AVI to make a dv2.. used force film.
I don't remember what the program's called, but it makes an avi out of a dv2.

Then I used virtualdub to frameserv, using resize (480x480).
Loaded the avi into CCE 2.5 SP.

I used 4 pass VBR, 3000 kbps max bitrate (yes! I even used a higher bitrate than SVCD standards and there was lots of blocks). I don't remember what the average bitrate was but quite high...

Hm I think that's all I can remember, does anyone see any obvious mistakes that could have made the macroblocks disapperar?

When I loaded the dv2 into tmpeg and used SVCD template (NTSCfilm) CQ 2500 kbps and quality 60 or 65 the quality was a LOT better, but there were still some macroblocks...

[Truman]

Everything seem to be OK. I don't know, what is wrong here.
However, I converted T2 to MPEG-2 480x576 VBR 4pass 1530kbps (min 1000, max 2450) with cce sp 2.50 and got very good quality, no macroblocks at all. Sorry, I have no idea.

[davidian]

Well.. hmm OK I suppose trying again wouldn't hurt? Using your settings.

But the minimun bitrate.. is there any point of setting it to 1000? (couldn't it be 0?) Just asking.

[kreg]

I'd like to try cce 2.5, but I can't find it. Any suggestions?

Maybe you could check out http://www.vcdsp.com downloads section you might find something you want there....

[kreg]

Hmm

Nope, seems to be a dead link tonight. I guess I'll just get it from you. Please email me 2.5 so I can use the framserver from VDub. I can't seem to find the trail version or any version of 2.5

here is the email address.

Thank you much.
