How to change QuickTime Mov to Mpeg-4
I got a request where someone asked me how to do a QuickTime Mov to Mp4 conversion using QuickTime Pro 7. The respond to this depends on what Mp4 file you want.
Someone may ask, "why it's counting on the Mp4 file I want? If you are a real Apple aficionado, you must not be unacquainted with QuickTime's export function!"
Uh-huh, it's indeed to open up QuickTime "Export" selection from the "file" menu and indeed to take converting "Movies to Mpeg-4", and click "Save". And even, you can just directly modify the file postponement from .mov into .mp4 to do the conversion. Yes, these are somewhat Mov to Mp4 change. But is it enough?
For some QuickTime newbies who are new to the process of Mov to Mp4 creation, things can be quite confusing. In some cases, they did the conversion just as above, but found the production Mp4 files cannot be played on the Psp or other Mp4 players.
Let's go back to the scene before "Save" click. Press the "Options" button right-hand "Export" box to pop out the "Mpeg-4 Export Settings" dialog. Under the dialog, you'll find there are 2 choices for "File Format" selection: Mp4 Isma and Mp4.
Isma (Internet Streaming Media Alliance) is an early alliance with representatives from all points of the streaming work-flow. Therefore the Mp4 Isma is especially good for streaming media over Internet and cellular phones with a low resolution. So if you are trying to get an Mp4 movie in tasteless or in Hd, take the "Mp4" file format.
Likewise, there are more than one options out there for "Video Format". "None" means you can just get music or audio off the former movie without any image frames. "Mpeg-4 Basic" defined the normal Mp4 videos in some kind of low compression ratio. "Mpeg-4 Improved" offers you Hd Mp4 video production using Mpeg-4 codec, while "H.264" also gives you the high definition video quality with H.264 (Mpeg-4 Avc either) codec. "Pass Through" is interesting. It just changes the Mov video box to be the Mp4 video box without any interchanges, and this, is what I mentioned above, the "extension modification".
So that's it. All the left is just to keep the default parameters or do some changes, and then, click "Save".
