Longer / non-Apple cables and charging the iPad

UPDATE (07/26/2012): at last a cheap ($3) Chinese cable that is actually worth paying for (if you do want to recharge your iPad with it - again, for iPhone / iPod touch recharging, generally, any cable will do)!

Do you find your iDevice's screen to be too blueish (or just too harsh for bedtime reading)?


iOS forums are full (see for example THIS, THIS etc.) of complaints of (mostly) bluish (or, in some cases, yellowish) screens. In addition, several articles have been published on the adverse effects of blue(ish) lights – see for example THIS and THIS (two very important and interesting articles!)

Benchmark: excellent multimedia converter HandBrake vs. commercial apps


UPDATE (07/27/2012): I've benchmarked Aimersoft Video Converter Ultimate for Mac 1.6.0 ($54.95). It converted the AVI file to Full HD H.264 M4V in 15:20, which means it's somewhat slower than HandBrake.

UPDATE (06/27/2012): I've benchmarked Aiseesoft Video Converter for Mac Platinum. (1080p conversion, using the new iPad preset; version 6.3.6). Another slow, expensive (even the non-3D-capable Standard version costs a whopping $35) and, therefore, non-recommended converter: more than two times slower than Handbrake. (It took 15:26 to convert the first five minutes of the test video.) Stay away!

Tutorial with Source Code: Exporting any Video to the Camera Roll


While I'm still working on the Camera Compatibility bible applicable to, among other applications, iMovie and featuring dozens of current cameras, to reduce the (otherwise, large) size of the final article, I've decided to separate (and publish earlier) two, distinct modules from it:

1. Explaining how you can programmatically export your video files to the Camera Roll of your iDevice and;

2. Explaining the secrets of deinterlacing, which will prove very useful for a lot of iOS users as several cameras (even popular, current ones like the Nikon 1-series or the Sony A65) (can) use interlaced recording and the iDevice (including third-party movie editor apps like iMovie) just can't play them back (or, when it comes to iMovie, edit) without some kind of conversion.

GoodPlayer developers release a hardware MKV video player "PowerPlayer"


UPDATE (11/Oct/2012): HERE, I've reported on the brand new (1.7) version's vastly reduced MKV hardware playback compliance now that AC-3 support had to be removed from the player. Please read it so that you can know when to use the new version for MKV playback and when not. (Generally, not for anything Full HD and containing AC-3 audio tracks.)

Multimedia player news: new ProPlayer version receives HW decoding toggle and Full HD TV playback


I've always liked and, for most playback purposes, recommended ProPlayer (AppStore link). While it isn't exactly feature-packed (you won't find, for example, audio, saturation or brightness boosting in the app), it has (generally) a well-behaving and -performing set of video and audio decoders. Most of these decoders are exactly the same as in AVPlayerHD, one of the best iOS multimedia players.

The latest player update description boasts “Hardware acceleration” and states the new version is "a major feature update":

Decent multimedia player OPlayer(HD) receives streaming audio boost and other features


While I don't consider OPlayer (HD) (AppStore links: iPhone; iPad) the best-performing or most versatile iOS video players out there, it still has some very strong and well-supported features like a very good MSMPEG4 and OGG Vorbis video decoder.

The just-released, new version boasts, among other things, support for volume boosting - something I really need when in a noisy environment or when needing as large a video playback volume as possible (see the annotated part of the screenshot; click it for a larger version):

Great iPhone app resolution enhancer and rotater RetinaPad becomes iPad 3-compatible


RetinaPad (Cydia store link) has always been one of my most favourite iPad jailbreak apps – it has done that Apple should have done: show iPhone apps in the maximal resolution possible on iPads, and also let for rotating them.

Enhancing the video camera of the iPhone 4S – part II (incl. reviews of frame rate booster apps Better Camcorder and SloPro)


At last, I had some time to go on with my article series (first one HERE) on the video camera of the iPhone 4S. As usual, I've made a lot of experiments and measurements.

Let's start with the 60p (60 frames per second) mode – something I didn't have the time to properly elaborate on in the first part (I was busy getting ready for the MWC trip and, then, for a very-very long skying holiday in middle-North Finland. Hence the big pause.).

Recording video at more than 30 frames per second (fps)

Best display content recorder "Display Recorder" tips and tricks, also for the (new) iPad (3)


UPDATE (06/19/2012): there are several new articles on competing, alternative hardware HDMI recorders. One of them is Elgato Game Capture HD, which is comparatively cheap ($200), sports both HDMI and component(!) input, is small, only requires a USB 2 connector and is compatible with both PC's and OS X Mac's. (Blackmagic Design Intensity Extreme is strictly Mac with Thunderbolt-compliant and doesn't have component input). However, it can't record 1080p signal, only 720p/1080i and can't deliver uncompressed footage to the host computer either, something that videographers wanting to built a very cheap Red One alternative really want (if you don't need uncompressed, direct footage, then, this won't affect you).
