rooVid 1.0 beta 1 was released today.

In short, rooVid makes it easy to take one video and convert it for multiple purposes. I use rooVid [1] to convert family movies I edit in iMovie and export them in two different formats for the web, one in h.264 the other in MPEG-4. I also [...]

In QuickTime’s export dialog, “MPEG-4 Audio” is “AAC”. Somehow iMovie and QuickTime are using a different dialog for their export “sound” options. Compare the two lists of compressors below:

Default Sound options when using ‘MovieExportDoUserDialog’

QuickTime 7 and iMovie’s dialog

The QT7/iMovie dialog has some clear advantages.

Shorter MPEG-4 Audio is re-worded as AAC (as far as I [...]

When I sat down tonight to work on my app, it just kept crashing. Seems a new exception, QTMovieInitializedOnWrongThread, was added to QuickTime. Searching on ADC produced 0 results. Google couldn’t even find anything about it. Fortunately, the error needs little explaining: I need to initialize my QTMovie object in [...]

I’m interested in being able to take an iMovie project and directly transcode that to some other movie type from within my software. My first thought was to learn how to parse the .iMovieProject and put the movie together myself. This scared me. After depressingly staring at a sample project’s XML for some [...]

Reminder: A QTAtomContainer is a Handle, a Handle is a Ptr *, a Ptr is a char *, so a Ptr * is a char **. If you want the data that a Handle points to you get it via *yourHandle. Yowza. Yes, I’m new here.

So, remember:

typedef Handle [...]

In the previous post, “Show user QT’s Export Video Dialog“, I showed how to present the user with the standard QuickTime export settings dialog. The next question should be “How can I figure out what they selected?”. For me, I only want to know certain settings for display purposes. If the user [...]

I want to write down how I’m presenting the QuickTime compression dialog. This post will be followed by another post describing how to figure out some of the information of what the user selected from the presented dialog. First things first, displaying the dialog:

ComponentInstance component = OpenDefaultComponent(MovieExportType, kQTFileTypeMovie); [...]

As previously stated, I’m working with the QuickTime API’s. Well, one thing I want to do is display a QuickTime compression settings dialog and be able to get some information about what the user selected. Today I wanted to get the selected compressions codec in the nice, human readable, string. First stop, [...]

I’m starting a blog. For my current project, RooVert, I’m fumbling through QuickTime API’s. Normally when I’m doing something new, the web has most of the answers. If the full answer is not there, I’m often pointed in the right direction. Well, the area of the QuickTime API I’m playing with [...]
