mp4 turning into m4v

Feb 20, 2013 11:13 AM

I try to export to MP4 but the file output turns out to be a M4V which my other program do not read. What am I doing wrong ?

    You should include audio (check the multiplexer tab too)

    Simply change the file extension from .m4v to .mp4.

    Have you tried an .mp4 file encoded with audio?

    I don't know anything about Director... not even sure what it is.

    So... I guess you can't get there from here!

    You're not doing anything wrong.  It's a change introduced by the 6.0.2 update.  H.264 exports without audio will use the .m4v container.  For now, you're best option may be to include the empty audio.

    I suggested that in post 5.

    Post 6 says he couldn't make it work.

    Do you believe that it becomes an .mp4 file

    at the moment of multiplexing?

    I was having the exact same issues.  On export (without the Export Audio box checked) it would change to an .m4v file and was unplayable - even with switching the extenion back to .mp4.

     

    My file had no audio so I wasn't exporting any, but when i checked the box and re-rendered it stayed as an mp4 file and it played back fine in all my video players (QT, vlc, wmp).

     

    Now, in the past I have exported many, many .mp4's without the audio box checked and it stayed an mp4 and had zero playback issues in other programs, so this absolutely has to be a bug in premiere or AME (running 6.0.3 CS6 btw).

     

    Great catch on this one, Cocovanna!

    Yes, the m4v is correct, in that there is only a Video Stream, and no Audio Stream.

     

    However, as many have discovered, some players do not handle m4v, or do not handle it correctly.

     

    With an Audio Stream, even an empty on, the mp4 will be correct, and those problem players will handle it properly, including the "silent" Audio Stream.

    Thanks Bill, just noticed Jim Simon's reponse after posting that it isnt a bug.  Kind of aggravating though - just wasted two days trying to figure this out.

    I understand. As Jim points out, it is more a "correction," but to one, who had done things one way, in the past, it would certainly appear to be a Bug. I can understand the confusion.
