Videography
I have had my eye on one of thos cool GoPro waterproof cameras that you mount to your helmet. But at $300 plus various accessories, it was hard to justify. So while wandering around CES, as soon as I saw the Optrix, I knew I had a solution. As John Willenborg, the inventor of the Optrix HD points out, you already have a great 1080p videocamera, so why buy a GoPro when you can make a rugged case for the iPhone 4 or iPod touch.

Unfortunately, Apple has never let screen recording applications into the AppStore. This is diametrically opposed to the situation on most other computing platforms, both mobile and desktop. Just some examples: Microsoft has never had any objection to mirroring Windows Mobile phone / PDA screens on a desktop computer.

I've long been working on my forthcoming full(!) tutorial and comparison of everything video playback on iDevices. Now that I'm also writing a full comparison of all iDevice file accessor and media synchronizing tools, I've also very thoroughly tested the video (among other things, MPEG2 TS) conversion of the, otherwise, excellent and highly recommended SyncPod (by iSkysoft) tool. This – and the recent, great jailbreaking and XBMC releases – made me publish a separate, dedicated article. This all means that, as usual, my article contains tons of never-before-published information on generic video conversion, cutting etc. related information. Feel free to ask (in the comment section) if you'd like a more thorough explanation on any of the discussed (sub)subjects!

I've played a bit more with creating Cydia packages. I've found out the following:

WARNING: this article can be highly technical and is definitely NOT meant for people that haven't ever tried hacking the camera of their iPhone 4 or 3G S. If I don't run into other obstacles (I find out something very important), the next one I publish will be meant for newcomers to iPhone 4 or 3G S enhancement. If you, however, are a seasoned hacker and/or a programmer interested in writing apps for Cydia and/or have previously used my hacking tools before and would like to know what the new versions contain, you will want to read on. AGAIN: this article is NOT meant for complete newcomers!
The new versions

Having dug deep into the configuration files and the video “hacking” of the iPhone 3G S (see my yesterday's post HERE [beware, it's quite technical and mostly meant for advanced users / programmers]; I'll also very soon post a full all-in-one 3G S article for beginners), I've found the „ 1080p” settings I've used there applicable to the iPhone 4 too – in addition to the default (here: true HD with full frame rate, near field-of-view and bad low-light performance) and the full sensor (high-resolution video with great low-light performance and, on the iPhone 4, greatly widened field-of-view but severely reduced frame rate).

I've just uploaded version 1.4 of my free(!), open-source(!) iPhone 3G S video recorder enhancer tool to Cydia. As usual, add the repository „http://www.winmobiletech.com/cy” or „http://winmobiletech.com/cy” to your Cydia client and download the new version from my repository. When the development is finally finished, I'll make the two programs be available in traditional Cydia repositories so that you don't need to access it from my private repository.
Main changes in this version:

I've just posted the new (1.3) version of my iPhone 3G S Video camera enhancer to my Cydia repository. (Please see my previous, dedicated articles [e.g., THIS] on accessing it.)
Unfortunately, when it runs under iOS 4.3.x, it has two main disadvantages compared to the pre-4.3 version:
- no on-device playback of anything over 1 Mbps. That is, you can't set for example 2Mbps as your video data rate if you want to watch the video on your iPhone.
- no Full sensor mode, also meaning less real resolution and worse low-light performance (but much better framerate and no „clicking” bug)
|
The video recorder of the iPhone 3G S can heavily be enhanced. As opposed to the iPhone 4, where the main enhancements are “only” making the field-of-view much wider, the data rate selectable and, with pixel binning, the low-light performance much better (by sacrificing some resolution and speed), the enhancements of the 3G S camera, in addition to the better low-light performance through pixel-binning, are waaaay superior: you can greatly increase the resolution, almost to the level of the iPhone 4 or traditional cameras.
