View Full Version : Video too fast when DVD authoring in IFOEdit 0.95

I have run the "DVD Author" function many times on different movies and movie scenes, and I get the same problem every time - video at about 2x-3x normal speed while audio plays normally in background. I have played with several settings and I get the same result each time. When I play the .m2v in Windows Media Player, it plays at normal speed, so that leads me to believe it's an IFOEdit issue.

Here's what I do (this is just a scene so that I can run several tests quickly):

- DVD2AVI a .d2v file (short 2 minute scene)
- TMPG the clip to .m2V (video only)
- In IFOEdit, DVD Author the scene with the .m2v and the .wav file that was generated by DVD2AVI
- Run PowerDVD to view the results

Maybe this is because it's just a short scene, but I have run the same test using Sonic MyDVD instead of IFOEdit, and the video works perfectly and it syncs perfectly with audio.

What am I doing wrong? Am I omitting an important step?

same problem over here. I certainly am interested in a solution for this... Anybody ?

Maybe this clip has 2 or more Vob-Ids and some of them have different fps than the others.
ie: Vob-Id 1 @ 23.976 fps and Vob-Id 2 @ 29.97 fps or 3:2 pulldown...

No, unfortunately this is an epidemic in my case - short clips, whole movies, 29.97, 23.976, non-interlaced, interlaced, 3:2 pulldown, doesn't matter. No matter how you slice it, IfoEdit runs the video way too fast while the audio churns along perfectly in the background.

I only used the clip example because it's an easy way to check the results without waiting 12-13 hours between each try.

I have had to resort to running everything at a very low bitrate and using Sonic MyDVD to get a good result. But there's no chapter option on MyDVD. So I don't want to give up on IfoEdit just yet.

I have the same problem... only happens after i do the Authoring step. I am getting buffer under runs when i author also.

Unfortunately, this thread has not gotten much attention from the big boys. I sure wish someone that's having success with IfoEdit on a regular basis doing this would chime in....

Until then, I am still in limbo when burning DVD's that require compression from TMPG.

I don't have a solution to this problem, but I have 'backed up' a lot of dvd's and have only had this happen once. It was The Freddie Mercury Memorial Concert dvd, the only thing about this dvd that was different from the many I have done is the soundtrack was PCM which I converted to mpa. I never found a solution & went on to other projects. :(

SAME prob too.

mpeg from ulead dvd factory, mainconcept plugin, and other give the same results... fast play...

i tried to change some flags in mpg, but always the same.... fast play... on pc and standalone...

using the same files works perfect with scenarist....

audio in ac3 or lpcm, same results... fast play...

i canīt see a light in the end of tunnel....

Have had the same problem with a project I have been working on (subtitling a home video of a nephew's schoolplay - I originally created a DVD w/o subtitles using Studio 7 and am now adding the subs. I was having problems with buffer under-runs, but I have got round those by taking note of a post elsewhere that suggested that multiple VOB-IDs cause problems with subtitles and also cause "stream will arrive too late errors" - what I am now doing is extracting the video and audio streams from the VOB files and splitting on each new VOBID. The plan is to then subtitle each section and re-author each section using IFOEdit.

What went wrong was the video would play at double speed, with the subs seemingly in synch with the video, but with the audio running at the correct speed.
:(

Like Dilligaf, I was using a PCM soundtrack (from a DV camcorder).

I have just used ac3machine to convert the PCM to ac3. Hey presto, the sound and video are in synch (subs need some slight adjustment by the look of it, but that could easily be minor tweaks due to my not timing the start and finish times of each sub correctly).
:D

One interesting point, in my long and fruitless experiments (before the ac3 conversion) I tried using the "The Microsoft Sound.wav" sound file as the audio in one authoring session. This sound file is of shorter duration than the video (several seconds compared to 4 minutes). The video played back at double speed for as long as the sound was present, then the video played back at the correct speed.
:confused:

Any of the experts got an explanation?

@Malow - what particular flavour of ac3 did you convert your LPCM to? I converted to 5.1, Heavy (all other settings to default - correction : default for bitrate was lower than I believe recommended lower limit so I set it to 384, which I believe is the lower limit recommended).

I know what you guys are talking about, I think. When I author in ifoedit, the movie plays fine on any software dvd player in my computer, or in my standalone sony dvp-c670d. Except for that the seconds count up "jumpy" (counts seconds like 9..11..1.10..13..12..14 all weird like that, but still the playback will be smooth. But when I track forward, it will freeze the video at the beginning of the chapter, so I have to scan back a little bit, then hit play, and it will play again. Don't know why this is either. When I try to play anything authored in ifoedit in my playstation2, it plays no audio, and the video skips by at about twice normal rate. Sounds like similar problem to what you are experiencing. So possibly try using different DVD players to test the movie, although it sounds like Ifoedit should be scrapped as far as it's dvd authoring tools go, it seems too buggy for my taste.

Same problem. I try and encode Terminator 2 using DVD authoring, and pop in the subtitles, chapters, and audio that I demuxed using VOBedit, and I get a 2 hour 20 min video compressed into 1 hour 49 min. DVD authoring is seriously broken on ifoedit.

I think I have a solution. Ifoedit's site specifically states that ifoedit will have problems if you try and author more than one VOB ID. So, my next experiment is to change the movie to use only one VOB ID and retry the authoring.

This may be why Derrow hasn't said anything on the subject since it's written on his site. Of course, you probably have to know what he's talking about as well since it's not really clear.

For those that want to try this before I have an answer on whether it works or not, and want info on how to make a movie use only one VOB ID before you do your reauthoring, visit this site:

I'll post my results, but it will take a while so don't expect them right away.

Forget it. I was thinking you could strip the stream into 1 VOB ID after modifying the IFO, but this is not working.

Interesting to see my thread span several months, with more members experiencing the same issues, but still no solution from the big boys.

I have long since jetted IfoEdit - it is worthless IMO except for analysis of PGC's. I have since discovered DVDShrink, which is absolutely awesome. It does everything you need, including re-authoring the VOB's after you're done. In fact, with most of my projects I don't even need TMPG anymore, as DVDShrink works faster and better. I use DVDShrink to edit, clip and make G-rated versions of my DVD's so my kids can watch them without the filth and violence.

Only one problem with DVDShrink - each edit starts a new chapter instead of retaining the DVD's original chapter marks - anybody know a good chapter-making program.....?

Happy compressing with DVDShrink, and save your Advil by jetting IfoEdit into the Recycle Bin :)

No - there is a solution, but it takes a lot of work. The way to do it is to extract each VOB ID into it's own directory with it's own IFO file, compress and remux each individually, and then join all of them back together again using VOBEdit. I was hoping for a simplier solution since some movies have a lot of VOB's, while others only have a couple.

For DVD shrink and the like - it's just got a plain ugly output as compared to a real compression engine, so if you want any sort of quality, you must use the old Ifoedit method. It's kind of like you don't have a choice.

If you use just the remux of the VOB's though, you end up with bad audio, so you're stuck re-authoring here. You just can't win is the problem.

By the way, I just did a test using the above method I mentioned, and it works fine. Here are the steps:

1. Rip video.
2. To make life easier, strip the streams of the wanted audio and subtitles using IFOEdit.
3. Seperate each VOB ID into it's own directory using IFOEdit.
4. Demux the audio and subtitles from each ripped VOB ID with VOBEdit.
5. Extract chapters cells from each of the new IFO files for each VOB ID using IFOEdit.
5. Recompress each VOB ID using your favorite compression engine.
6. re-author all the streams back into VOB's using IFOEdit authoring mode.
7. Re-join all the newly recompressed VOB ID's back into one movie file using VOBEdit.
8. Create new IFO files using IFOEdit.
9. Copy subtitle colors from the original IFO file into your new IFO file using IFOEdit.
10. Enjoy your newly recompressed movie with much higher quality than DVDShrink.

I think that sums it up. Is it clear enough?

Actually, scratch this. The times don't line up. The chapters also don't line up - I should have 73, but I have 63. IFOEdit is just broken. That's probably why we haven't heard anything is because they know it's broken.

I'd donate my $5 to it to help further development, but it seems that activity has been dead on it since November so it would be wasted $$$. SOmething tells me that there isn't going to be any new versions for a while either. I guess it's still good for ripping streams though.

yes, unfortunately (or maybe fortunately), the guy that developed IfoEdit got a cush job offer to go to work for a big development company (I think it's DVD-XCopy, or something like that - I remember reading a discussion thread about it here somewhere).

Anyway, like I said, IfoEdit is just too cumbersome and broken as you say. I have not done a quality comparison between DVD Shrink and TMPG, but I will try to do so and will post my results if I experience something different.

I have mainly used DVD Shrink for its excellent editing and re-authoring capabilities. The last few I've done were small enough to fit on a DVD-5 so I didn't have to compress at all. But I feel sure I can get a work-around without IfoEdit the next time I need to.

I am still interested in an easy way to re-insert original chapter points though once I've edited and clipped. I may just have to tinker with all the many tools I have in my arsenal. This whole process is a very pick-and-choose-tool world :)

Have the same experience. I've read all the guides regarding converting an avi to DVD and used different tools (tmpgenc+Vmoddub, VirtualDub, NAndub, BeSweet, BeSliced) and numerous runs with Ifoedit 0.95 but no success so far. I don't get any error messages while processing the avi except the warning message in VirtualDub/VmodDub regaring a VBR MP3 audio stream.
The audio and video is fine individually (m2v + wav) but when muxing through ifoedit the video seem to run at 50 fps instead of 25. The audio is fine though.

Well, I guess he might be out of a job soon. SOme judge is on DVD-X-Copy's case and going to shut them down:

By the way, I think I have a theory on why the Cell times are messed up - I'm assuming it's because it doesn't know how to deal with VBR data.

The movie that I made above, plays fine on a stand alone player and at normal speed, but the chapters don't work. So, the only way to see the end is to wait. There is something messed up though since the end starts to error out.

In the NTSC and DVD2DVD-R/CCE world, IFOedit is replaced by Scenarist or DVDLab due to problems like this.
From mrbass's site:
"If you use IFOEDIT to mux/author NTSC DVDs the movie will play just fine in PowerDVD. However, in your standalone dvd player if you skip to the next chapter or fast forward after a few seconds it'll freeze and there's nothing you can do. It won't display the correct time rather just freeze. Your choice."

Check out mrbass's site if you are dealing with NTSC streams.

I found the following remedy to these problems:

Strip the audio. Convert only video stream with tmpgenc into m2v file.
Convert the .wav file into ac3 using BeSweet.
When running IFOEdit on the m2v file and the resulting ac3 file everything works for me.
Hope this helps you too!

In response to bwalerud's input - that's essentially what I have been doing (and reported earlier - so it's nice to have confirmation from someone). Only difference is that when I extract (is that strip?) the audio and video from the VOBs I get .m2v files anyway, so all I have to do is convert the .wav files to .ac3 (using ac3machine, for which BeSweet is the front-end).

I have also managed to produce subtitles for a number of the separate scenes of the (home) movie (of a school play) that I have been working on and then multiplexed the .m2v .wav and .sup files to get new VOB and IFO files for each scene. Once I have completed the whole play/movie, I then intend to merge the separate VOBs - I read something about this in another thread and I think I need to use VOBEDit for this. Will report back once I have got that far.
