View Full Version : .m4v QuickTime problem

2nd September 2010, 03:06 PM
I used handbrake to rip some episodes of a dvd I have. I use MP4 file type. When the encoding finishes it has the extension: .m4v

I can't open the file with QuickTime.

Isn't Quicktime supposed to open m4v files?

Do I need to purchase QuickTime Pro?

Do you mean can't, or won't? Quickime can open m4v but I think the default app for them is iTunes. Try changing the extension to mp4 and see what happens (mp4 & m4v are the same thing).

I've had similar problems as the OP.

99.999% of the time, the latest version of HandBrake delivers an M4V that won't open in QuickTime, with the message:
QuickTime could not open this file as it is not a movie file.

See thread here (http://forums.mactalk.com.au/57/88484-encoding-video-dvds-mp4-itunes-2.html) - and is compounded even further when I select the (H.264) Codec, and rather than compress 4.5 GB or 7.5 GB worth of DVD, the M4V winds up at a max of 25 GB in size.... something has just gotta be wrong there.

Since the idea was to playback on a Classic iPod, with (H.264) Codec turned off, the moment I have HandBrake set to create Chapters, it'll copy just fine into iTunes... but it will produce another error when I try to sync the iPod to it - can't recall the error but it just says it can't do it.

Since all that hassle, I only use HandBrake to convert a DVD into an MP4 and I then use iSquint 1.5.2 (http://www.macupdate.com/info.php/id/19769/isquint), as suggested by johnq, to convert into another MP4 - after which all those ridiculous problems vanish.

I'm using a Mac Mini Intel Core 2 Duo, with 2 GB RAM, 30 GB free space, running Mac OS 10.5.8, with all updates up-to-date.
