Creating Preview tracks using Photoshop



> Luckily you can create your own previews in PhotoShop and add it in 
> QuickTime Player.


This was news to me so I tried to make it myself on photoshop.  I'll 
list my step as I am not sure I'm doing the right thing:

1- I got my equirectangular jpeg and converted it into 6 tiles (using 
panocube plus).  I opened them in photoshop and created a new file 
with the following dimension: 
Height 250 pixel
Width: 1500 pixel
I selected these dimensions by extracting a preview track I've done 
before using the export feature in QT player.

2- I added each tile as a layer to the new file in the correct order. 
Flattened layers.

3- Saved for Web > Jpeg, Quality: 60%.  The jpeg file was 58k.

4- I opened my new jpeg file in quicktime player, Edit > Select All, 
then Copy.  Closed QT.

5- Opened my qtvr file (271k, window size: 400 x 250) which I want to 
add the preview track to, Changed controller to movie controller.  
Edit > Add Scaled.

6- Then in Edit > Enable Tracks.  I switched the new video track to 
off.  Saved. My new qtvr file is 276k?!? My qtvr gained just 5k.  And 
ofcourse the preview track is not working online.

What am I doing wrong?
