tmpgenc, rempeg2 & ifoedit

[DS9]

hello everybody,

after having experimented a lot with divx i finally came to the conclusion that it just doesn't offer quality comparable to dvds. so, i got a dvd+r recorder. i'm quite confident with it, when using burning films smaller than 4,7gb. stripping streams with ifoedit works great either (Thanx derrow for this ultimate utility).

the only thing i have problems with is transcoding an mpeg2 to a lower bitrate. after about 20 encoding-attempts, i managed to transcode and remux "the fast and the furious" wuith rempeg2 & ifoedit. now, i tried exactly the same settings on training day and got artefacts and a flickering picture. using tmpgenc the video looks fine, but i get out of sync audio.
i did all the encoding by following exactly the doom9-guides.

so, my questions are:
1. is it possible that i have to use different encoding settings for every movie? what am i doing wrong, what settings do u use?
2. is there a way to mux an m2v created by tmpgenc with ifoedit without losing audio sync (using the template ifoedit created for tmpgenc didn't work for me)??
3. what exactly is the rebuild pts option in ifoedit for?
4. i'd like to offer my assistance in the development of ifoedit as i suppose it's really an awesome utility, which could evolve to a godlike status if it could mux cce und tmpgenc m2vs better. i've got some programming experience and would be glad to contribute

than alot in advance

I'm running into that problem as well. Using ifoedit and such, I now have 100% perfect results when just stripping streams or trimming the disc in a data sense.

However, when needing to transcode the movie itself, it doesn't always work. The problem is not consistent with a certain length of film, either... I had trouble with some very short Robotech DVDs, and managed to have a perfect transcode on the longer Snatch. I am being driven batty by Fight Club... those morons somehow encoded the basic film itself, with only English audio, at about 8GB. urgh. and it doesn't want to process correctly.

I am using only TMPGENC and IFOEDIT at this time... can anyone tell me:
1. Is rempeg a necessity for this?
2. Am I missing something obvious?
3. Should I be improving my system before I try this?

I run a P4 1.8ghz, all 7200x drives (2x120GB), 512mb of memory.

1. no, it isn't. but its benefits are great as you won't get sync or chapter problems.
2. none that i would know.
3. you needn't at all. an mpeg2 encoder card would increase encoding to realtime speed, but this isn't a requirement at all

[DS9]

come on guys... please post your expeiences... ha anyone ever managed to remux an m2v created with tmpgenc? which tmpgenc/rempeg2 do u use?

[AND1]

why did you remux the fast and the furious. After ifoedit you should be able to fit it onto a dvd-r easily.

Transcoding problems galore! Haven't tried Remux but even programs like Cinema Craft Encoder add "padding" when they transcode. The only way to get TMPenc to save in sync requires you to split the streams, compare their lengths and then use CoolEdit or other program to cut or add silence to make the audio length equal to the video length (which you can check in TMPGenc). Then you can remux the streams in TMPGenc. Every TMPGenc transcode I've done has had out of sync problems. The only good thing about TMPGenc is that you can add filters to the conversion step though it increases the conversion time. I was looking at programs like the new Canopus Procoder but it uses a USB dongle and there is no demo available. Still awaiting that perfect piece of software...

so, what do u use for transcoding? rempeg2?

DS9 the ac3 streams are usually delayed/advanced eg thay dont start the same time as the video stream.
Look what the delay/advance is and when you re-mux you must add this value back eg with BBmpeg

or Use AC3 cutter (doom9.org) and cut or add to the start of the AC3 stream so both the AC3&Video start at the same time-now when you MUX with Tmpgenc both will be in sync.

but when using bbmpeg i'd have to reauthor the whole thing. isn't there a way to just remux with ifoedit AND maintaining sync?

My guess is(as I have only played around with MiniDVD`s). That if you take the vob file, and it contains 1 Vid & xAC3 streams. MuX as I sugested in my last post, repace the original Vob with the new one(keep the name the same) and it should work. I would recomend you use BBmpeg as it seems to make compliant VOBS.

[DS9]

can bbmpg create vobs? i thought it creates .mpg files which have to be reauthored to vobs then...

what happens to the chapter points then?

[DS9]

please... could anyone respond?

BBmpeg creates VOBS

Cheers

[DS9]

ok, thanks... found it... but how do i maintain chapter points?

The Procoder demo is available from the Canopus website. I've tried it, along with the <cough> "fix" from demo to full version and it doesn't compete with CCE. The features and final quality are nice but, quite frankly, the speed (or lack thereof) makes it unusable.
