    How to rotate an mp4 video clip? 19th Jun 07 at 9:52 AM
    Id be grateful if anyone can help here.

    I have a mp4 video file that needs rotating. Is there any way of doing this without loosing the picture quality. I have used QuickTime to re-encode it but it does loose its quality. I have also tried using the pass-through function however either the picture doesn’t display when opening in anything other than QuickTime or the picture displays the wrong way around again (back to square 1). :confused:

    You can rotate clips in Windows Movie Maker (Free with XP) but I don't know if it can process MP4 files.

    Using SUPER convert it to AVI then use VirtualDub to edit the video, re-save it and then convert it again using SUPER.

    This is brilliant! I know it wasn't written for me, but I've just used both programmes, and it works a treat.

    Under 'video > filters' you find the option for rotating it but you need to select a format to convert the video to before this option becomes available.

    Thanks Asus.

    For anyone else wanting the quickest solution, I just now used avidemux to convert a mobile phone video that was filmed at portrait angle by accident.

    It is a small download, free and does the job entirely stand alone as described above. For an MP4 clip off a Nokia I used:

    MPEG-4 ACV in the top box, set to Copy then MP4 in the lower box, then Filter > Transform > Rotate > 90 deg. Click 'Output' in top toolbar (hover mouse over icons to see descriptions) and you see a static preview of the rotated video. Now click the little floppy disk icon to save this output, if it takes 5 mins to process this means it's probably working correctly.

    Test playing the output in Quicktime or similar before sending/uploading.

    And if anyone knows how to successfully stitch either MP4 or MOV files together to make a single longer movie clip using Avidemux (it is supposed to be possible via the APPEND option but I get an unknown error each time) then pray tell!

    Hi
    Maybe Avidemux is being fussy.
    It will expect the two mp4 files to have the same (or very similar) characteristics. Such as same codecs and bitrates etc.

    With Linux I can use a program called MP4Box like this:-
    Code:
    MP4Box -cat file1.mp4 -add file2.mp4 output.mp4
    There's a Windows version of this MP4Box program called YAMB.
    MP4Box doesn't just glue the files together, it re-packages them.

    This is a report that I found on a website:-

    I was able to join the files provided using YAMB. Note that the second video file duplicates a few seconds from the end of the first, so that a brief part of the final scene is repeated. Here's what I did:

    1) Open YAMB, click the "Editing" button in the sidebar, and double click "Click to join supported files".
    2) Drag "1.mp4" and "2.mp4" into the main window in that order, leaving all streams enabled. Set the output to the same directory as "3.mp4", and click next. Wait for the process to complete and the lowermost-rightmost button to say "Finish".
    3) At this point, you have a fully functional MP4 file ("3.mp4") with original audio sync and no video issues.
    YAMB is from here:-http://yamb.unite-video.com/features.html

    (It won't run on Linux systems)

    Well, YAMB partially works. I tried to concatenate 5 small mp4 clips, it keeps 'losing' some so I get 2 or 3 of the clips in the result, not all. This is after a few tries and double checkings.

    FWIW MP4Cam2AVI seems to happily join mp4 clips:

    http://sourceforge.net/projects/mp4cam2avi/

    but the output is avi which may not suit your requirements.

    My attempt with YAMB resulted in a list being shown with the embedded properties of my MP4 files. Using this info I was able to go back to Avidemux, use the correct options (for example, have to select aac audio) and get a good result!

    Excellent.
    In the current version 2.5.4 (r7200) you click the "Filters" button on the left, then "Transform" in the pop-up, then "rotate" in the middle pane of the pop-up, then the green plus below it to add that filter to the active section. Choose your angle and click OK. Then if in the right hand pane you click the Rotate word, its background turns blue showing it is selected. THEN the Preview button at the bottom right becomes active and you can see your masterpiece. If it is OK, click the "Close" button to go back to the main screen, from whence you can save it. I have successfully copied as an mp4 and converted to an avi.

    I found an even easier way since I could not find my own instructions again in the MSE forum!
    And this method works for any video format that Youtube will accept - that's a lot.
    - Upload it to Youtube. There is a no-brains-needed rotate tool.
    Takes some time and will then be published, nicely rotated. Can download it again then.
