I opened an old project file today that was created with 0.8 and discovered it had changed the in/out points of several clips on the timeline. To be clear, the clips themselves are starting and ending at the correct place on the timeline but they are showing the incorrect material from the source footage. I guess my first question is 'why?' These are MJPEG AVIs so there is no fancy time encoding -- just a sequence of frames.

Second question.... while trying to repair this, i'm using the 'duration' window that pops up when you double-click on a clip in the timeline. I know roughly where the in/out points of each footage should be so i'm trying to adjust the clips to show them. I'm making a few assumptions that might be wrong seeing as things aren't working as I expect them to.

So I assume "crop start" is the in-point of the source footage I set for the timeline clip and that "crop end" is similarly the out point of the source footage that I set for the clip on the timeline. As in "this clip plays seconds 5 to 7 of the source footage." I can set "crop start" fine but "crop end" doesn't seem to take.

I see that there is also "duration" -- why is that there? To my knowledge, kdenlive does not edit clip speed in this way... is it to give the user an option of whether to set in/out points of just an in and a duration?

Finally, anyone have any sweet techniques for recovering the old in/out points in a more automated way?

I hope someone understands this explanation of my problem. I'm am using kdenlive 0.8 from the Ubuntu PPA.

Not sure about your in and out points, may be worth a dev taking a look at your file

The crop end is the duration from the end of the file. So if you had a 60 second clip, a crop end of 00:05 would crop it at 55 seconds. As I understand it anyway!
