Summary

0002708: Opacity in composite transition is not really 100% (background shows through)

Description

Background images show through to the foreground with objects in the foreground (for example: titles) with the composite transition and opacity set to 100%. Uploaded file is PNG image showing the problem.

Steps To Reproduce

1) Insert a complex-like background (like black with white lines all over the place)
2) create a title clip with a png black box or coloured box for the foreground
3) insert complex-like background on video track 2 and title clip on video track 1 with composite transition
4) note that usually the background lines will show through to the foreground (sometimes faint, sometimes very noticeably).

Notes
(0008237) thatgamesguy (reporter) 2012-09-01 16:24	This bug is preventing me from continuing a project that I started a month ago.

(0008253) j-b-m (administrator) 2012-09-02 18:03	I cannot reproduce. Are you sure that the color for the foreground object in your title has no transparency? If not, can you please archive a simple project that has the bug and attach it here or mail it to me (jb at kdenlive.org)? To archive the project, go to Project > Archive project and select the "Compressed Archive" checkbox. It will create a .tar.gz file containing the .kdenlive project file and all clips used in the project.

(0008259) thatgamesguy (reporter) 2012-09-03 03:08	Uploaded a sample project that displays the issue reported.

(0008260) thatgamesguy (reporter) 2012-09-03 03:15 edited on: 2012-09-03 03:16	Uploaded output to youtube: http://www.youtube.com/watch?v=r_6wUDRf_z4 [^] The second part of this video should show a title clip with the same image going from one side of the screen to the other, but I forgot to insert it...

(0008266) j-b-m (administrator) 2012-09-03 23:49	I managed to reproduce the problem, thanks for your files. This is a problem in MLT, I sent a mail to Dan to have his opinion on this.

(0008271) j-b-m (administrator) 2012-09-04 21:36	Thanks, the issue was found and fixed in MLT's current git. So you will need MLT from git to have the fix or wait for the next MLT release (0.8.4)
