Limit on number of clips / length / filesize / resolution?

[fridgefreezer]

I'm putting together a DVD and the source files are quite plentiful - over 500 separate video clips (some running over an hour), probably as many photos again, and perhaps 100 music tracks.

 

Can anyone tell me if there are absolute / advised limits on:

- Maximum number of clips in a project

- Size of a clip in Mb

- Length of a clip in minutes

- Resolution of a picture

- Total number of clips in use in a project (EG actually added to the timeline)

 

After a few crashes / lost files (which has so far been fixed by an update) I have taken to doing the project as ~10-minute blocks / chapters and saving the resultant video for combining later.
