About structure for media (M)

M1
- Filetype (video or sound)
- Timeline Layout Color
(orange or purple)

« Color » : This is ALSO a dynamically computed method, with following formula
-If position of media M is even in timeline description: color is orange
- If position of media M is odd in timeline description: color is purple

As a consequence, when we do manipulation such as on previous slide, Media description does NOT change either !
Only timeline changes from (M1, M2, M3, M4) to (M1, M2, M4, M3)

2.5 What about other objects ?
All other “visual” objects in Alexandra should also be “ported” to use relative time TR:
-

comments (“bubbles”)
“black cursors”
“sommaire” comments

reason is always the same, if a user has commented a video and you move the video, you
should move the comment with the video, and so on...
