29 Oct 2008 Exporting H.264 video to a Nokia 6234 as MPEG-4 via QuickTime Pro

Via Tim Prebble's blog, some nice video podcasts by Christopher Willits from XLR8R TV. The story so far:

  1. Part 1 (Ep. 42), the basics.
  2. Part 2 (Ep. 46), using Ableton Live.
  3. Part 3 (Ep. 52), a MIDI pickup and a GR-20.
  4. Part 4 (Ep. 74), recording at SnowGhost.
  5. Part 5 (Ep. 82), automation clips.

You can download nice 640-by-360 H.264-encoded QuickTime movies of each episode (approx. 100MB per video), and I thought it'd be nice to watch them on my Nokia 6234 phone. (These seem to be very popular here in New Zealand; at least, after I bought mine the next four people I met with a 3G phone also had a 6234.)

After reading a useful Nokia article on creating mobile videos, I fired up QuickTime 7 Pro and started exporting the movies with different settings. This is what I came up with for the best results (and about 28MB per video):


Video export settings.


Audio export settings.

The nice thing about doing this myself is that I could keep the audio bandwidth high (so it sounded pleasant) while scrunching the video (so the phone could play it cleanly). The audio bitstream accounts for half the file size.

I would love to have time to actually try this stuff myself. I have a GK-2a pickup and an old GM-70 I picked up on Trade Me; one day I'll manage to get it all set up and have a play. (Perhaps by then I'll have a Graphtech Ghost setup and an Axon AX100 instead.)

10 Jan 2006 1.467GHz G4 Upgrade
I've been reading more about CPU upgrades for my Quicksilver 2002 Power Mac. The Giga Designs dual units all use 7447As with no L3 cache. Fastmac have a 1.467GHz single G4 upgrade for USD300 that uses a 7455 with 2MB L3 cache that might well be better value for money. Who knows.

Right, back to work...

06 Dec 2005 Mbox CoreAudio driver for Tiger is here
I'm a bit late with this (apparently it's been out since September), but the Standalone Digidesign CoreAudio Driver 6.9.2cs2 for Mac OS 10.4 (phew!) is now available. This means that I can use Chris's Mbox on my Power Mac without having to shell out to upgrade Pro Tools, when I already have GarageBand.

Come January, I plan to stake out a corner of the upstairs room here to assemble my various bits of music gear into something I can use to actually start recording some music.

04 Aug 2005 Dashboard widgets for music
Chris Randall links to createdigitalmusic.com, who have a roundup of Konfabulator and Dashboard widgets for music makers. And there's Amnesty, which frees your widgets from that grey parallel world and lets them live on your desktop.

15 Jul 2005 Mmmm, upgrades...
If I had the money to spare, I'd like to buy this dual G4 1.6GHz CPU upgrade and a Radeon 9800 Pro video card for my Quicksilver Power Mac. (My uni-N revision, apparently, is 11.)

In the meantime, SMARTReporter looks useful, given that I don't trust the second hard drive. (Via this article on Mac maintenance.) TechTool Pro is apparently very good, also.

Oh, and I've managed to install a Dvorak keyboard layout from this page.

05 May 2005 Tiger-related browsing
There's a good, if rather long, review of Tiger on Ars Technica. The guy mentions Path Finder as a replacement for the OS X Finder. It looks like upgrading the video card might be a good move, also.

On a completely unrelated note, JavaScript Object Notation (JSON) is 'yet another' lightweight data-interchange format. Might be useful at some point.

And Backpack is 'yet another' web application, this one aiming to be a complete personal information manager. These things are getting pretty sophisticated.

In other Mac news, I replaced the Power Card in Chris's PowerBook, and now the battery charges up, but nothing continues to happen when I press the power button. So I need to find out who does hardware servicing for Massey, and send it to them.

30 Apr 2005 My First Mac
RCN Associates are selling some Quicksilver 2002 PowerMac G4s (800MHz, 256K L2 cache, CD-RW drive) for NZD395. So I bought one. It seems to have survived the brutally disinterested treatment of the courier, and I am now trying to install OS X on it. It took me a while to notice the eject button on the keyboard, though.

Some initial useful-looking links I've found:

Apparently the OS X Tiger upgrade is only available on DVD, so I'd need to upgrade my CD-RW drive, or possibly try an external FireWire drive (e.g. one of my spare DVD drives in one of these). So we might put that off for a while.
