    My daughters wedding video is on VHS tape. As a surprise I was going to convert it to a DVD movie. Using my DVD recorder and not knowing how long the video tape went for, I set my recorder for 2 hours. It went longer than that so had to pause the tape and pop in another DVD to get the last 43 minutes. I mention this only because I don't remember if I set the recorder to 1 hour for the last bit which may have caused my problem in the first place.

    I ripped both disks using DVD Decryptor and used AutoGK to make them into avi files using 10mbs/second for custom conversion. I then went to join them into 1 file using either VirtualDub or VirtualDubMod but can't because the first file is 512x384 and the second is 656x496 - I don't know how this happened because I didn't make any settings changes (except MAYBE the recording size as mentioned above - would this have been it?).

    I've tried to teach myself and read tutorials on the vdub filters but I'm still stuck. I suppose my main question is - do you have to use Full Processing Mode when using filters as nothing changes for me and I used Direct Stream Copy. If so, I'm going to end up with a HUGE file as the movie is 1 hr 57 mins long. I've got 157Gb free - will that be enough? Do I then use AutoGK to resize it to a manageable file size again?

    I have made a DVD movie out of the 2 files using Nero so I have achieved what I set out to do, but I ultimately would like the 2 weddings files as 1 file, any resolution, the best quality I can get, for data storage purposes.

    Help? Suggestions?

    TIA Olly

    the files on the dvds are already dvd compliant, so don't re-encode them. at all. get vob2mpg and use the free part to convert both dvds to single mpeg-2s with whatever they have for an audio stream.

    once you have the 2 mpeg-2s use mediainfo on them and post screenshots of the "text" version of it's output here. and pleas post how big the mpegs are. once we have that info the next step can be determined.

    Sorry, I've been busy the last few weeks and haven't done as you suggested yet. I've determined that it's AutoGK that's the culprit though. The vob files of both DVD's are 720x576 when ripped. It's when it goes through conversion with AutoGK that the first DVD's (1hr 57mins) resolution changes. If I set them at 720x544 the second DVD rip (43 mins) comes out that size but the other one comes out at 656x496. If I set them to 656x496 then it comes out at 512x384. Why does it persist in making the bigger file a different size? I've tried a number of times and regardless of the settings I make AutoGK does it's own thing with this file.

  4. Why don't you rip the 2 DVD's as 1 file each using DVD decrypter, then join the 2 with something like mpg2cut2, or avidemux ? You could even join vob's with vobmerge or mpg2cut2 , for example.

    This way it's faster (no time spent re-encoding), and you lose no quality, as opposed to re-encoding with xvid, and there is no resizing. Everything is "original"

    EDIT: sorry - I missed that you're doing some filtering in between? with vdub? If so, you might as well use it to re-encode and join as well.

    No, it's you that is the culprit. AutoGK doesn't know you'll be rejoining them when done; it just tries to find the optimum resolution for the files, given the filesize you set and the quality it likes to wind up with. You could set a fixed width in the beginning and then they'll have the same resolution at the end, but perhaps not the same quality. Or you could set a fixed width and use a 1-pass target quality setting at the default 75% and then you could join them afterwards.

    However, if the final format is to be a joined and filtered DVD, I have no idea why you're messing with AutoGK in the first place.

    No need to be so aggressive. If there's a better way of doing things then I'd like to know - hence why I'm here looking for help.

    I did set the resolution to 720 in Advanced Settings in AutoGK but it still changed it. Is that what you mean about
    setting a fixed width in the beginning? Surely AutoGK doesn't have to know what I'm going to do with my files - shouldn't it just encode to the settings I've set? Why allow you to make settings if it's going to override them? I've made custom settings on a number of different custom file sizes and it hasn't made a difference. As you said AutoGK has it's own idea of "the quality it likes to wind up with." I'm not entirely up to speed with what happens with encoding so any light you can shed on this would be appreciated.

    And I was looking at filters in VirtualDub 'cos I needed to crop a little bit off the bottom of the files as it had the wobbly bit you often get on VHS tapes when it hasn't been tuned in properly.

    Hadn't heard of these programs so haven't used them, but will have a look - thanks.
    I'm self taught and have learnt through trial and error and whatever tutorials and help sites I can find. However, any tutorials I come across always seem to assume you already know something (a lot?) about video encoding in the first place so it's never a real beginners guide or the tutorial only covers a few aspects of the programme. I don't have anyone to bounce things off as I seem to be the only one that I know who is 'into' this.
    I haven't been able to find an easy to follow (and complete) tutorial on a lot of programmes (VDub and it's filters for one) - if there's any available on any of these programmes please point me in the right direction. I usually make a book of them and print them off. Got quite a library of lots of bits and pieces!

    I like the idea of vobmerge but have a question. The blurb on the site says "Don't use it to join several DVDS, just use it to join a vobset from same DVD" so does that mean I can't add the vobs from my first DVD rip AND the vobs from the second DVD rip to merge into 1 big vob file? I realise that's exactly what it's saying - just wondered why it can't do that if the vobs are the same size etc. and I'd be just adding 2 DVD rips not several.

    Yes, that's what I meant. But I don't believe you if you're saying AutoGK changed the width you set. Post a log of one of the encodes where you think it changed the width.

    If you say I'm being agressive, well, you're probably right. However, I have a soft spot in my heart for that program, since I had quite a lot to do with it while it was in development. It's a mature program now and when something screws up, 9 times out of 10 it's the fault of the user. Go ahead and prove you're that one in ten exception.
    And I was looking at filters in VirtualDub 'cos I needed to crop a little bit off the bottom of the files as it had the wobbly bit you often get on VHS tapes when it hasn't been tuned in properly.
    AutoGK can also do custom cropping in its Hidden Options (CTRL-F9). But again, there's no point in using it if you're making DVDs ultimately. An intermediate XviD or DivX AVI degrades the quality too much and unnecessarily.
