Using Skype with a Bluetooth headset and via AirPlay (with Audacity tips and tricks)

image

While in the gym, I tend to make / receive a lot of Skype calls to my wife or relatives. As I exclusively use stereo (A2DP) Bluetooth headphones in the gym to give me absolute, cable-less iPad 3-video-watching freedom while exercising, I've also run into problems related to the Bluetooth bugs of Skype: most of the time, I couldn't just use the headphones I already worn to conduct the call. Instead, I needed to use the speaker / microphone on the iPad itself, making my environment hear what both I and the other party say. Therefore, I decided to investigate the problem and come up with solutions to it.



Selecting the best DVD player app & an It's Playing bugfix

UPDATE (08/09/2012): in the comments section below, I elaborated on deinterlacing. Note that I'll devote a complete article / tutorial to these subjects (using X.264 / HandBrake / Episode to deinterlace etc.) some time. Before that, it's mostly HandBrake's (default) decombing that will be your best friend.

UPDATE (08/04/2012): THIS thread has a lot of discussion of the subject. Remember to prefer my statements to ones that state the opposite! (The thread is full of factual errors.)

Phone Disk users, attention!

image

I've, along with several other tech writers (see for example THIS) recommended “Phone Disk” and “iExplorer” in several of my articles (see for example THIS).



Tidbits: AirPlay, editing videos of the Videos app, advanced exposure locking, AAC recording etc.

Let me present you with some links to my (more important) posts of the last 24 hours at user forums I'm also very active at all around the Net. I, while, generally, incorporate information I find out / post in user forums in later, larger roundups with a much broader scope, I don't generally dedicate a separate article to questions I answer for users.

HERE, I've explained how one can edit (unprotected) videos synched via iTunes to the stock Videos app with Avid Studio. (The vastly less capable iMovie, along with several other video editos, can only access the Camera Roll and, therefore, can't directly edit videos sychronized as true movies.)



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)?

image

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

image

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!



Work-in-progress version of my iPhone 4S video camera enhancer tool released (only for coders!)

I've been working on updating the iPhone 4S-specific version of my camcorder enhancer tool for some hours (earlier, dedicated article HERE).

It's still far from being finished but, should you

1, need it right away and
2, know iOS programming and



Tutorial with source code: Exporting any video to the Camera Roll

image

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, one that explains how you can programmatically export your video files to the Camera Roll of your iDevice and



GoodPlayer developers release a hardware MKV video player "PowerPlayer"

image

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.)
