Hi..Having been sent a couple of music concert files written to a DVD from the USA....I want to tidy them with some cropping etc..... I have 4 Vob files on my Hard drive and I can play any on Media Classic player and they all play with the audio in sync.... My attempts to encode to avi or mpg (all 4 together or separately one at a time) have all resulted in failure ..i have tryed all the programs I usually use plus a few more recommended via Google....but it looks like I am beaten old man....Clearly my expertise I thought I had is not up to standard.... The problem is audio sync,everything I try results in this problem... I wonder if anybody could just nominate a program or method to try.... Many Thanks H.H.
Hi..I have Used these ..or a combination of...ImToo DVD Ripper..DVD2AVI..VDub Mod...Womble Mpeg-VCR....Xilisoft DVD Ripper..Convert Movie...TMPGenc...... I have also tryed extracting the Audio with DVD Audio Extractor..I really am out of my depth in this one ..I just cannot get round the fact that the VOB's are perfect ..H.H.
I'd start by demuxing with DGIndex. That will give you elementary streams with the audio files having a name that tells you what (if any) delay they had (compared to the video) in the original VOBs. Then I'd try authoring with those files to make sure you don't get any audio sync issues at that point. Assuming there are no problems there, do whatever you need to with the video demuxed by DGIndex, keeping the audio stream(s) untouched (assuming you're not cutting out anything). Use the new video and original audio streams to author the new DVD.
Thankyou ..I hope you can just comment here...I Used DGindex....Now I have 4 x Vob's from one DVD.....at this stage I am concentrating on the 3rd VOB so hope this does not upset things.... First when loading I got this Warning...Opening GOP is not closed..The First few frames may not be decoded correctly.... ?? I now have a vts_01_3.d2v and a vts_01_3 TOI 2_och 256kbps Delay -379ms.ac3 files.... What do you suggest I do now..? Thanks H H....
Sorry I forgot to get back to this last night. It sounds like you're demuxing VOBs from the same titleset individually. Assuming there's only 1 title you should open them together by selecting all the VOBs at the same time (using the Shift or Ctrl key) or adding them one at a time from the Open dialog. Otherwise you'll end up with GOPs that are split between VOBs, causing the first few frames to be unreadable. You may not see the difference watching the video since a single frame is only going to be a small fraction of a second, but a couple of frames missing can make a big difference in audio sync. Edit: If this is getting more complicated than you want it to be you can also use DVD Shrink to create a single VOB from the entire VTS. Just turn off VOB splitting in Preferences.
Alternatively, you may try encode with VSO DivxToDVD (free version), then burn with e.g. Nero. Sometimes a simple solution might create great results: http://www.afterdawn.com/software/video_software/video_encoders/vso_divxtodvd_free.cfm Just keep adding the vobs before hitting 'convert'. Good luck!
Vurbal....I think I was doomed from the outset when after an unsuccessful attempt to rip the DVD I was told to copy the files to my hard drive.....I have now used DVD Shrink to encode the DVD into one vob file ( 4,162,096 ) ..So I am in debt to you... I would like to crop the vob , save as an mpg and edit....I would really appreciate your advice on this ...I have used DVD2AVI / VirtualDub and Tmpgenc in the past ...I think DVD2AVI has been superceded by DGMPGDEC...However hopefully you will advise me..Many Thanks
When you say crop do you mean cropping black borders from the sides or something else? If all you need to do is basic editing (ie cut out sections or append sections) you can use an MPEG editor to make the changes and then author the new file(s) to DVD. Some editors to consider (listed in order of versatility and features) would be Womble MPEG Video Wizard, Womble MPEG2VCR, VideoReDo, and Cutterman. If you're only going to need the program for a single use I'd recommend a trial version of one of the Womble products or VideoReDo. If you want something to keep using in the future I'd give all of them a serious look to see what matches your needs. Edit: BTW you're correct that DGIndex has superceded DVD2AVI.
Vurbal...these DVD's I received are music for me to study...I will not be rewriting them...I want to get them into a format where I can play in certain players with mark in/out etc on my desktop and the format I always find best is mpg....Re Cropping..Yes there is some edge noise but my main objective is that I would like to get rid of some of the border irrelevant space so that the musician is more of the main focus....I find that TMPGenc does not offer the cropping ability VirtualDub....at present I am encoding to an Mepg1 using Imtoo DVD ripper...Once its finished I will check it for audio sync....and if no problem ...I will try DGIndex to VirtualDub(apply Resize filter and crop)and frameserve to TMPGenc.....I think this will work for me...Thanks H.
Vurbal..Bad news I am afraid...Part of the DVD is missing so I obviously had settings on DVD Shrink wrong ...it missed the end and returned to the start instead?..Having encoded it to mpeg1 using Imtoo DVD ripper ..and playing it in Media classic player..there are still audio sync problems and to be honest I am wondering if its actually the DVD itself ....There does not seem to be a pattern to the sync problem ..ie it just seems to go in and out...Is there a method for checking ? I presume the audio length should = the Video length..H
I have analysed the ac3 file with an ac3 tool and it has literally hundreds of CRC errors in it....So I presume I am really up against it...Oh Yes ...Media Classic Player left the end off and put the start on in its place....VirtualDub never???? HH
I've never had to fix an AC3 stream, but if it were me I'd try using AviSynth to open the video. If you're not familiar with AviSynth it will probably take some time to figure out what you're doing, but since VirtualDub can open AVS files it's the next logical step. You could try opening the ripped VOB directly using a script like this (insert the path to your own file in the quotes): DirectShowSource("C:\Wherever\filename.VOB") The downside to this is that you'll get with uncompressed audio instead of the original AC3, but hopefully it will be in sync. Then you can do whatever you need in VirtualDub and you can compress the audio again if you want. If this works you can also crop with AviSynth and frameserve directly into TMPGEnc to encode your MPEG-1 files.
