Hi - what 3rd party applications do people use to convert Video.ts files to mpg4? Thank you.

MacbookPro, Mac OS X (10.5.2)

    Can you tell us more about these files.

    what 3rd party applications do people use to convert Video.ts files to mpg4?



    I prefer MPEG Streamclip (free) but it requires the QT MPEG-2 Playback component ($20) be installed but if all you want to convert are the VOB files in the VIDEO.TS folder to MPEG-4 or H.264, then iSquint (free) will work on its own. Assuming the files are not encrypted, just drop the VOBs to the work area and encode using the "TV" preset for VGA (640x480) output.

    The movie was taken from a 8 year old video camera and burned directly to a DVD using a stand alone DVD burner. What resulted are two folders on the DVD, Video_TS and Video_rm. Within each folder are several documents with extensions I don't recognize - .BUP, .IFO, .VOB etc.

    I believe the files are now encrypted, but I'm not sure.

    That's pretty much all I know about the files.

    I'm not sure, but I think the files are encrypted. How could I tell for sure? I think I'll go ahead and purchase the QT piece then use Streamclip ... I'm assuming that will work whether or not the files have been encrypted.

    I'd like to know, for future reference, how to tell if the files are encrypted or not?

    Thanks.

    If you used a standard commercial "home" DVD Recorder, then your files are not encrypted. They are, however, encoded as MPEG-2 video multiplexed with AC3 audio (VOB) files. Neither of these compression formats are "natively" compatible with the QT structure. And, while they will play in either the Apple DVD Player or Front Row, the files are not edit compatible in iMovie '08 as they are. Your first step is to re-compress the files to a format that is compatible with iMovie '08 for editing as stated below.

    Probably the easiest way to tell for sure would be to copy the "Video_TS" folder to your hard drive and then open it in either the Apple DVD Player or Front Row application. If the content plays at all, it is not encrypted. Another way to test it would be to download an application like iSquint (free) and drop any non-zero VOB file to the open application and attempt to convert it using the "Optimize for TV" option. The default setting would be an MPEG4/AAC file which would be compatible with iMovie '08. If the VOB file converts and can be imported to iMovie '08, then it was not encrypted. While this work flow is not the best in terms of quality, it should demonstrate whether or not the work flow works which, in turn, would indicate if there are other problems here.

    Hi ~ I followed your suggestion and dragged the VOB files into iSquint. It successfully handled 5 out of 6 of the files and I was able to take them into iMovie and begin editing. One of the files was unable to be handled in iSquint > I got an error message reading "could not find codec parameters"

    I thought I'd try your other suggestion for that file so I bought QT MPEG-2 Playback component to use with Streamclip, but then found it requires Quicktime 6 and my machine runs QT7. ....so my questions are >

    1) do you have any suggestions as to how I can convert the wayward file with the error message (above)?
    2) Did I buy the correct QT MPEG-2?
    3) If so, can I successfully have both QT 6 and 7 on my machine?
    4) Where would I get QT 6? I couldn't find it on the apple site.

    Thank you so much for your suggestions ...I really appreciate the help.
  • Keren Sagehorn Level 1 Level 1 (20 points)
    Thank you for our suggestions ...every little tidbit adds to the picture for me. See my post below ...if you have any suggestions I'd appreciate your advice. Thank you so much.

    What was the name of the file that did not convert?



    I thought I'd try your other suggestion for that file so I bought QT MPEG-2 Playback component to use with Streamclip, but then found it requires Quicktime 6 and my machine runs QT7.



    DMG file should contain two folders. One is good for QT versions up to QT v6.3 while the other is for QT v6.4 through QT v7.4.5 (current).



    1) do you have any suggestions as to how I can convert the wayward file with the error message (above)?



    May depend on your answer to my first question above.



    2) Did I buy the correct QT MPEG-2?



    Yes.



    3) If so, can I successfully have both QT 6 and 7 on my machine?



    It is possible (or at least used to be according to QT Kirk/search for his instructions in the QT forum) but not necessary here.



    4) Where would I get QT 6?



    You might try a Panther or older OS X installation disc if you have them.

    The name of the file that wouldn't convert is > VTS011.VOB The other files that successfully converted were named VTS012.VOB, VTS013.VOB etc.

    The error message said (in full)
    An error prevented VTS011.VOB's conversion from starting. See below for the explanation:

    /Users/ksagehorn/Desktop/VTS011.VOB: could not find codec parameters.

    Was hoping it might have been a file not connected with the title set. Unfortunately, it is. First guess would be a hit to the file during copy. (I.e., some small bit of corruption preventing proper reading of the data or file header. You can try recopying it and see if this makes any difference. (Small chance but possibly worth a try.) If that doesn't work, I would try a different application. However, since the other files were recognized correctly, I would tend to think the problem is associated with the file itself and not the software.
