Description Roberto Castagnola 2016-01-08 20:58:34 UTC

If I use a png lumas file with a different aspect ratio than the project one, the shape of transition is resized keeping the aspect-ratio of the png file, so I get 2 bar on left and right of the clip where the transition is not applied.
I will attach a simple test project in dv_pal format where I have created a black and a white clip color, starting with the balck clip and ending with the white one. During the transition, using file radial.png found into kdenlive package, the black clip is resized leaving 2 white bars on left and right.
If I convert the file to pgm format:
   convert -strip radial.png radial.pgm
the transition covers all the clip size as expected
(I have to use -strip option to strip comment, or the transition doesn't work: maybe I shall open an other bug for this?)

Furthermore, if I enable 'Use GPU processing' option, kdenlive crashes when using png file, but not when using pgm file


Reproducible: Always




kdenlive version: 15.12.0

Thanks for your report and feedback.
We are going to switch back to ppm files for the next 15.12.2 release.
