Package: openshot
Version: 1.4.3-1.1
Followup-For: Bug #787226
Dear Maintainer,
openshot has been fun, and productive.
I happened to notice in Debian unstable, that
after doing
$ aptitude full-upgrade
$ openshot
importing images or video clips and
either
adding images or video clips to
openshot's time line, or
rendering/exporting a video
colors are corrupted.
It seems to me that I'm basically seeing the same
bug as Marco.
I think it's also reported at
http://openshotusers.com/forum/viewtopic.php?f=11&t=2364
I didn't upgrade openshot.
However, I believe melt was upgraded from
0.9.2-1+b1 0.9.6-1.
I spent a little time debugging it.
Here's what I found.
melt seems to render the colors fine outside of
openshot.
$ melt image.png
This suggests to me that version 1.4.3-1.1 of
openshot may not be entirely compatible with the
new version 0.9.6-1 of melt, which is what I'm
using.
I worked around the bug by adding alpha channels
to an image and video.
For an image, I did
gimp->Layer->Transparency->Add alpha channel.
Then I exported it in a .png format which the
"file" command describes as
PNG image data, 146 x 160, 8-bit/color RGBA, non-interlaced
For a video clip, I did
openshot->File->Import files
right click on imported video clip->Add to
timeline
right click on video clip on time
line->Properties->Effects->toolbutton1->Alphagrad->set
position and max parameters to 1.0.
I hope that helps,
Kingsley
