iMovie App Runs on iPhone 3GS

August 27th, 2012 No comments

I was surprised to see that Apple’s iMovie iOS app runs on my iPhone 3GS (not jailbroken), even though Apple does not officially support it. It makes me wonder if it is just a stunt to get people to buy new iPhones.

“Ultrafast” video compression with x264

July 19th, 2011 1 comment

The fastest video compression I have seen so far is using the x264 command line tool with its “ultrafast” preset. The resulting file has no audio, so it requires an extra step with QuickTime to finish the process. I recently review the compression software Elgato Turbo.264 HD Software Edition, and it was indeed faster than iTunes and QuickTime Player when converting to iPhone-compatible videos, but I noticed that x264 was faster still. Here are the steps you can take for “ultrafast” video compression.

iMovie HD Available Here

August 17th, 2010 243 comments

The last good version of Apple’s iMovie was version 6, later called iMovie HD. At least that’s my opinion, and it’s shared by a few others. The later versions became more of a video manager (and not a good one), and a very rudimentary editor (and not a good one).

Realizing, but not admitting, how much people hated the new iMovie, there was a period when Apple would let you download the previous and now-abandoned iMovie HD, but it is no longer available from Apple, even on their Old Software List, so until I’m given a Take Down notice, I’m putting iMovie HD up for grabs here. Of course you’re trusting that I haven’t embedded some kind of nasty malware or anything, which I haven’t.

ImageSnap: Capturing a Video Image with QTKit on Snow Leopard

September 14th, 2009 22 comments

ImageSnap is a Public Domain command-line tool that lets you capture still images from an iSight or other video source. You might remember Axel Bauer’s original isightcapture tool (that is no longer supported but still works on most systems). I wanted a similar tool with source available so I could make feature changes or at least recompile with Apple’s ever-changing architectures.

At some point Apple introduced QTKit, a new and oh-so-welcome abstraction bringing QuickTime programming into the 21st century. Nothing against die-hard ANSI C programming, but it fits awkwardly into what are otherwise clean Objective-C Cocoa programs.

Rather than provide a detailed tutorial about using QTKit (sorry if you wanted one), I’ll just point you to the ImageSnap code so you can take a look at a few useful things like starting a QTCaptureSession, capturing output with QTCaptureDecompressedVideoOutput, and saving an NSImage to disk.
