On my machine, navigating through original clips is way too slow. Also I
have 4 video tracks, with mostly 2 tracks having a video at any given time.
Proxy clips are actually making the whole thing very usable, if not really
comfortable.

I think it tries to get the original clip length, and from the error
message, seems to not get a useful answer. If it returns a length of zero
(or negative) in case it reaches the maximum analysis length, then it would
explain why my clips get all shrunk on the timeline.

I will fiddle a bit more with that checkbox, as I think I had other issues
with sub-projects that I imported.

As I mentioned above, does libavformat then return a size of e.g. 0 if it
could not analyze it fully ?
Is there a cmdline tool that I could run on these WAV and video files to
see the failure mode ?
