Assignment Two

Convert to QuickTime




Instructions for converting your animation to a Quicktime movie.

Firstly - go into the Mac labs, load up your assignment, and press "M".

This will tell your assignment to save as a quicktime file. It'll ask you where to save to, and then will go and make a quicktime version of your animation - easy hey?

Well - not quite - there is no sound.

You need to add that seperatly.

To do that find a copy of Quicktime Pro, open the audio file with it. Click edit->select all. Now click edit->copy.

Open the movie in quicktime. Click edit->add to movie.

And that adds it.

Instructions stolen from "http://instruct1.cit.cornell.edu/courses/mus120/BouncingToDiskS2004.html"

But what if your animation has LOTS of sound files. Well I think you could add them one by one.

OR

You can go and get a program that records the output of the program, and save it as a single audio file, and add that. I used a program called "Audio MP3/WMA Recorder" found at "http://www.sound-recorder.com/software/audio-mp3-wma-recorder.htm" .

The free version of that program only saves 60 seconds of audio - but guess what - that's exactly the maximum time our animations were allowed to be. Set it recording, play the movie. If you werent fast enough you might need to edit the blank sound from the front of the file.

Now use the instructions above to add that soundtrack to the quicktime movie.

But what if the file's too big? Mine was 80meg BEFORE I added the music. Well you can tell Quicktime to export the movie - and you get a choice about the quality level. For my sixty seconds of movie the sizes were:

Broadband Low - 777k
Broadband Medium - 2.2mb
Broadband High - 5.8mb

All these were pretty poor quality to watch though. The largest one was almost ok. But it depends on how important the quality of the movie is to you.

LAN quality is better - mine was 10meg at this level. The quality still isnt fantastic - but its not too bad.


So Now you have the file - email it to me (Medium quality if possible) and I'll put it up on the website.

If you dont have access to Quicktime Pro - if you can get me the quicktime file and the sound file then I'll add the sound in. (one audio file please - if you cant record the audio yourself, I'll need a windows version of you animation too).
I dont know if you can use the Export-as-quality level thing without Quicktime Pro, so you might have to send me the 80-ish mb version. In that case, email me and we'll work out how you can get it to me. I might be able to meet you at uni and get it, or you could post me a CD or something. Email me at jawapro AT gmail DOT com.
