Encoding with TMPGEnc Plus, with VBR 4-Pass?!?!

[DaeMoNiC]

Hi there.

Im slightly new to the forum, although I know quite a few different tricks, as well as a million ways to burn a DVD. CURRENTLY, I'm working on trying to find a way that is 100% FOOLPROOF to convert (S)VCD to DVD Compliant Mpegs WITHOUT AUDIO SYNC ISSUES! However, I'm trying to do this with TMPGEnc, and so far, I've got an 85% success rate, without having audio issues. I want to correct that other 15% of failure.

So far, the best I am doing is re-encoding it WITHOUT demuxing, but when I re-encode, Im using the VBR 2-Pass. HOWEVER, my question to ANYONE whos reading this is: I have heard that people on the internet rip their (S)VCDs using a VBR 4-Pass. When I tried in TMPGEnc, I couldn't find it, so back to my question, where would I be able to get the VBR 4-Pass in TMPGEnc?? Someone help if they can, because after I perfect the method of creating perfect DVD compliant Mpegs, I was going to post it all on here. But I want it to be at LEAST 95% fool-proof. Someone get back to me, I'd truly appreciate it.

Cinema Craft Encoder (CCE) does multi-pass encoding and I think that's what people are referring to in the posts.

[DaeMoNiC]

Yes, but Im not talking about JUST ripping it, Im talking about something along these lines. I'm taking a (S)VCD that someone has ALREADY ripped from DVD using VBR 4-Pass, and I want to RE-ENCODE it to 48Hz audio, and do it USING the VBR 4-Pass. Would everyone say thats the way to go? By using CCE? Or is there any way to do it using TMPGEnc??

Sorry to butt in here , but i'm wondering how will you know it's SVCD from the web. Most of the stuff that I get from kazaa for example is AVI. Can i assume that if the resolution is 480x480 that it's SVCD.

Thanks in advance,

VC

Daemonic; I do not believe (anyone, please correct me) that CCE will handle mpeg2's.

VC: MPEGProperties (in the Tools section) will tell about any mpeg file. An Mpeg2 at 480X480 is likely an SVCD file, but could be re-multiplexed in TPMGEnc to be sure.

CCE can do 9 passes. But the manual states that after 4 passes, quality doesnt really improve to the human eye..

[DaeMoNiC]

Thanks guys, I do appreciate the help.

The thing is, I'm not really sure about how to use CCE, because up until now, I've only been using TMPGEnc, and thats what I'm trying to figure out perfectly before I put any guides out. Thing is, in TMPGEnc, they have an option to use a 2-Pass VBR. I'm guessing that would be better than just using a single pass, but not quite as good as using a 4-Pass, obviously. What I was wondering is this: is there any way to make TMPGEnc use a 4-Pass VBR? Like a downloadable template, or something that would 'unlock' that option? Something along those lines. I guess thats what I'm really asking... I could be (and probably am) wrong, but I'm hoping I'm not, otherwise my method of creating a "PERFECT" DVD Compliant Mpeg is only going to be about 85% successful, in which case, most people would discredit it and usually not even try it. I don't want that, because I know that it does work, unless the original Mpeg is flawed, and has been corrected (such as dropped frames, etc, etc). Any ideas, anyone?

No. TmpGenc does not support any more than 2-passes for VBR. Though I have seen many posts here that equate Tmpgenc 2-pass VBR quality with CCE 3 or even 4 pass VBR quality.

If your source really is SVCD, re-encoding is rareley necessary to make it DVD compliant, there are a number of tricks that can be used to avod this. Remember, re-encoding ALWAYS reduces quality (no matter how small the reduction).

Hi Bugster.


Well, heres what I do. I basically created a template for TMPGEnc with the help of a friend of mine, and we set the video to Constant Quality (CQ) at 100%, so that the video quality doesn't lose anything. We use the SAME SVCD as both the video and audio input files (Only 1 file) And then we re-encode it with a minimum bitrate of 1500, and a maximum bitrate of 4500, with an average bitrate of 2520. Because theres NO demuxing or remuxing involved, 85% of the time, there is absolutely zero audio/video sync issues. But every so often, the SVCD that we have is damaged so on and so forth. I was figuring that if I use the VBR 4-Pass (Which now I know doesnt exist for TMPGEnc) that it would clear up all sync issues. BUT, I guess I'm going to have to stay within my reach, and only use the VBR 2-Pass.

See, heres the thing. MOST of the SVCDs that I get are DVD-Rips, and when they're ripped, the people who rip them rip them using the VBR 4-Pass, and the quality is amazing. However, they encode it as a NORMAL SVCD with 41hz, which needs to be upsampled. However, Ive discovered that the second you demux with TMPGEnc, you screw up the sync. By the time you remux, youve DOUBLY screwed the sync, so its a lose-lose battle. With my method, there is no demuxing or remuxing, so it STAYS one file, error free. In your opinion, if I have an 85% success rate right now, using my method WITHOUT using the VBR 2-Pass, do you think I would achieve greater results if I DID use the VBR 2-Pass?? Please get back to me, let me know, I'd really like to find a conclusion somewhere in this mess...

Why not try SVCD2DVD?

It will do all that for you with no re-encoding of video.

[DaeMoNiC]

Faceman, quick question though. how can it possibly make a real dvd video out of an SVCD without at LEAST encoding the audio? And is that the exact name of the program, SVCD2DVD, or is there another??

Hi all,

Sorry thata I get in.

DaeMoNiC, some people rip with DVD2SVCD and they use CCE as an encoder, remember that you can use CCE or TMPGEnc with DVD2SVCD, so they use CCE and VBR 4-pass.

DaeMoNiC:

here is the name of the software:

SVCD2DVDMPG

and the site:

DaeMoNiC Whne you use TmpGenc to re-encode a mpeg file, it is de-multiplexing and re-multiplexing wether you realise it or not.

In order to do the encode you request, first it has to decode the input file to raw uncompressed avi frames, and seperate out the audio and video parts because they need seperate processing. Each is then encoded to its desired output format (m2v for video, mp2 for audio), then it is re-multiplexed before being written back to the output file. Of course all this is done internally, a few frames at a time but essentially it is the same thing, so I don't think you are really achieving much advantage over the much simpler methods leaving the video alone entirley.

I haven't tried DVD2SVCD personally but I have heard a few good reports about it, why not give it a go.
