CCE Experts! Help needed badly!

[therick]

Alright I have been fiddling with CCE for a while and I really like the quality I am getting from multipass VBR...I have two problems currently...

1. The .mpv files that CCE is giving me are 720x480...I am frameserving 352x480 (CCE outputs 352x480 MPEG-1 in this situation)...how do I get my .mpv file to 352x480???

2. The .mpv files that CCE is giving me have like a 2 second delay...so that when muxed with the audio(pulled and encoded from VDub) the video is ~2 seconds behind the audio...

OK, the details...my source is VHS...captured at 352x480 and frameserved using vdub...

I am really stumped by this and would appreciate any help anyone can offer...I am working on samples if anyone needs one, but I don't think that the samples will really help...it is probably just something that I am doing wrong...

1. CCE doesn't change the resolution. How are you checking the output resolution? If it is 4:3 aspect ratio on output, it is because the Display Aspect Ratio has been set to this, not because the resolution has been changed. Also, CCE allows you to choose MPEG1 or MPEG2 regardless of the resolution.

2. This is purely a multiplexing issue. Use bbMPEG and adjust the audio1 offset to bring the sound back into sync.

kinneera - thanks for the reply...

you were right...I just didn't understand what DAR was...

but as far as the audio-video sync...I am still new at this, and I think it is something that I have heard about the weirdness of .mpv files...but here are the .mpv files alone...I have tried muxing them (I have muxed stuff from CCE before with no problems) and the mpeg1 stream plays correctly while the mpeg2 stream does not...this is really what I don't understand and have never seen...

the clips (.mpv) are here:

Well, there's nothing "weird" about .mpv files, they're just elementary mpeg video streams (more commonly called .m1v or .m2v by other programs). There appears to be nothing instrinsically wrong with your files, although they don't have audio, so I can't try multiplexing them myself.

If you are familiar with bbMPEG, one of the options you'll see is a set of input boxes that allow you to set the delay before various streams in the file begin to play. By adjusting these values, you can generally resynchronize audio that is uniformly out of synch (but not progressively).

There's no reason why the MPEG1 should be differet from the MPEG2. That said, I would wager a guess that you are using TMPGEnc, and using the VideoCD and SuperVideoCD multiplexing settings respectively. TMPGEnc's SVCD multiplexing generates improper SVCD offsets, which will case a/v sync problems in a majority of standalone DVD players.

I have found that cce will change the resolution of my 704x480 caps to 720x480 if DVD compliant is checked in the video settings.

@kinneera - no, I never even tried to use TMPGEnc to mux(thanks to this site)...I always use bbmpeg to mux and I have never had any problems until now...I have tried SVCD and MPEG2 in bbmpeg to the same effect...

so it is not weird at all that with the same source file CCE gives me a 4 second mpeg1 clip and a 1 second mpeg2 clip?

I put the audio out there...

again kinneera thanks for your time in helping out a dumbass

Where are these settings in bbmpeg for setting a delay before a file starts? You may have solved a problem I have been having with multiplexing some ac3 and mpv files with bbmpeg. I thought it was dvd2avi delaying the ac3 file.

[kinneera]

@therick - even if the default settings have always worked for you before, sooner or later there will be a time when it doesn't! That said, the two video clips you provided had the same playback length on my computer. Also, both of those links are to elementary video streams, one in mpeg1 and the other in mpeg2. Neither has audio. (Open them up in TMPGEnc's complex demultiplex dialog - you'll see each has only a video stream). It is indeed weird that the two are behaving differently on your computer. I suspect that maybe it has something to do with your mpeg2 codec, but other than that I'm not really sure what the problem is. In any case, I'm glad to help.

@jaw2957 - the settings in question can be found under "Settings | Program Stream Settings". At the bottom are a set of boxes labelled "Startup delays". Adjusting the audio1 setting will affect the first audio track multiplexed into the file (and audio2 the second in an SVCD, if applicable). One nice thing about DVD2AVI is that it will tell you the apparent offset, but since it is not involved in the multiplexing (or even the encoding process) directly, it can't actually affect the timing of streams in your file. Just be aware that in my experience, DVD2AVI is not always correct and the default value of 180 often works. Also note that if an offset is needed, be sure to add or subtract it from the existing 180.

@kinneera - did you see the audio that I put up on the site? it is right beside the two streams...nonetheless, you were exactly correct. I installed the MPEG 2 codec package from this site about a week ago and this is the first .mpv file that I have used since then. I thought that might have been the problem, but quickly decided it wasn't (incorrectly). I have done it on my work machine...and yes the same thing happens with those mpeg2 codecs installed and with them uninstalled. Weird. I guess a little warning to those using that codec pack. Or maybe my machine is just retarded or something. Anyway, thanks for the help kinneera...it's always good to learn something new.

Yo! i'm not sure if you have already overcome the audio sync error, or how u encode it.
I encode audio with HeadAC3he, which is able to read the delay needed automatically (i rip my ac3 with DVD2AVI), and then when u mux the audio with the video it should be in sync
