Invalid transitions using 'Add to Timeline'

[Johan Pretorius]

Openshot version 1.3.1
I am trying out OS.
Imported a few images and lined them up on Track 2.
Add transition "fractal1" to snap to end of first image. Direction is "down".
Play - it works fine.
Add transition "fractal1" to snap to start of second image. Direction is "up".
Play - first transition does nothing but second work correctly.

If I remove any of the transitions. The other one works correctly.

I deleted the second "fractal1" transition and added another type. I then deleted the one I just added and re-added the "fractal1". Seems to work. (?)

Hi,

Could you reproduce it after running OS in a console and put us the result here ?
What is your system, version of mlt (use https://answers.launchpad.net/openshot/+faq/1032) ?
Thanks.

[Johan Pretorius (johanpretorius2026)]

I have a gentoo 32 bit installation.

The debug.py does not work on my system.

media-libs/mlt 0.5.10

Are you using KDE ?
 You should do a upadte of your mlt version The last is the but she introduces a bug in the preview very horrible. The mlt Team is aware and it seems that the git version resolve this issue.

[Olivier Girard (eolinwen)]

I precise that I can not reproduce it.

[Johan Pretorius (johanpretorius2026)]

I'm using gnome 2.32.1.

Gentoo's MLT is 5.10 and portage does not yet provide the latest.

If you cannot reproduce it it means it is probably fixed in the latest versions.

I'll wait for gentoo to provide the updates.

Thanks.

I can confirm this, but it only happens if you put transitions back to back on the timeline.

Here is a quick way to check this: import a couple of images and use the "Add to timeline" function. Choose a transition and fill in 3.5s for the length (assuming the standard length of an image is 7s). If you playback, the first transition isn't working. The second one works, but in the wrong direction. The third doesn't work, etc.

If you do the same but fill in 3.4s for the transition length, all is fine.

If you put more than 3.5s for the length the result is a big mess, so it would be nice if the transition length can not be more than half of the image length.

Added an upper limit to the size of fade and transition length when using the 'Add to Timeline' feature, to prevent invalid transitions and fades from being added to the timeline.
