Still Alive Tribute by Eric Schwartz for Amiga playback
« on: June 23, 2008, 12:38:42 AM »
Eric Schwartz released a tribute to the Amiga called  "Still  Alive"  a  few months ago on YouTube. There's also an MP4 version of it, but so far, there was no Amiga native playback even though the animation itself is  not  very demanding  (320x200  in 4 colours). The main problem was sync'ing the video with the music -- especially when the  frame  rate  of  the  video  is  not exactly  50  Hz  or  60  Hz.  Latter  also needed a playback routine of the original mp3, with less CPU demand (otherwise only 68060th would be able to play it back).

This is an Amiga  and  MorphOS  compatible  playback  with  ECS/AGA/P96/CGX support.  The  audio has been converted from 44 KHz 16 Bit stereo to 22 KHz 16 Bit mono with ADPCM encoding as a compromise. A 68020+ should be enough, but this has not been tested.

The playback needs AHI, but otherwise should find a  suitable  screen  mode itself.

The only difference to the version shipped with the Deneb USB board is that under  MorphOS  it opens a 16 bit screen as somehow otherwise the rendering is not correct.

Enjoy and send your feedback to Eric Schwartz ;-)

The animation (3.3 MB) can be downloaded from

No. Moviesetter AFAIK can't playback four minutes of continous audio sample and keep that in sync.

I can't get it to work with the music. I have installed AHI on my A1200 030/50, and selected Paula audio, and when I click on the StillAlive file, there's no music. :(

@platon42

There is a much much better way to do this....... just make the animation an Anim5 or Anim8  and convert the audio to IFF/8svx 20hz (or is it khz?) on Digital Sound Studio 3.0..........then the animation is simply synced with SCALA MM300 or MM400

Eric Shwarz really needs to get this app.

also one can play back the MP3 with a MASPlayer or Delphina.  But I would go for the 8svx option and it will sound pretty darn good.

Im still not sure why Eric chose to use a Mac for editing....all he needed was SCALA, or perhaps a standalone DVD recorder or DV Cam with S-Video input. You can get both for less than $150
CD32 is actually the best Amiga ever made by Commodore!...

Be sure you have AHI unit 0 configured correctly.

You are free to try it yourself. I am sure Eric will provide you with the 3.7 MB anim5 format file and the mp3 which in IFF/8SVX 8 bit mono in 22 KHz has a 3.8 MB file size (and this does not include the credits tune) which will sound much worse than the 16 bit resolution IMA-ADPCM file used here (the archive is only 3.3 MB in total).

And I doubt the Scala player will keep the lip-sync necessary -- I *really* doubt it. Moreover, the player won't work on RTG nor on MorphOS.

But please, try it. I'd like to see the results.

Does anyone know why the music won't play on my A1200? I have AHI installed, and I have selected Paula in the AHI settings. I've got 16MB RAM, so that couldn't be an issue.

Can anyone help?

 As Chris said, set AHI unit 0 (zero) as default sound output.
Goodbye people.

I\'ll pop on from time to time, RL is acting up.

Ooh, thank you for helping, I got it to work, I just had to  choose the 14bit Paula option.

Wow, that was so beautiful, I'm glad to finally see it running on a real Amiga instead of YouTube.

Eric is the best, he fills me with hope.
