The embed tag.

This is the code I use to put the avi files that my camera puts out onto my myspace pages.

 
<embed allowScriptAccess="never" height=600 width=800
src=http://www.houseofdahn.org/feurig/art06/flicker/MVI_8117.AVI >
<br><a href=http://www.houseofdahn.org/feurig/art06/flicker/MVI_8117.AVI
 >href=http://www.houseofdahn.org/feurig/art06/flicker/MVI_8117.AVI</a>

Which roughtly produces this.

Please note that myspace is a little finicky with returns (the return or enter key) and will often try to encode them if you look at the source code or if you get the non fancy editor because you arent running IE then you will see a bunch of <br> tags in the code. Delete them and life should be better. Also note that if you dont add the allowScriptAccess="never" that MySpace will add it for you its kind of creapy but it keeps the script kiddies away.

Converting AVI files to MOV files.

The avi files out of my camera dont seem to work without some sort of wacky middle wear and while I might take an "It works on my browser" approach I want to maximize my audience. (My browsers are firefox and safari under OSX) The irony of course is that the Video for Windows (.AVI) format breaks on Windows (do your best gomer pile well SURPRAEZE SURPRAEZE) I converted the above movie using iMovie. I dont much like iMovie but it works and its included in OSX. Here is the basic process

open iMovie
create a junk project
import (file-->import) your avi
drag the clip into the content bar thingy.
export the file
