Context too fuzzy to make a bug report. Someone could help to track the root problem?
![]() Rendering crashed just after creating empty .mp4 file. ![]() Rendering succeeded when disabling video track containing title clips. Viewing clip in project monitor is fine with all title clips. My title clips contain only 1 text string on video track 2, and some video on video track 3. Note: in my project, in project monitor, without any transition between title & video: the title appears on a black background, and no video is shown. I had to add a affine or add transition to see my video. On a new project, the video is shown in the title's background without any transition. Question 1: what should be the "normal" behavior? Error log extract of rendering crash: ![]() (melt:2459): Gtk-WARNING **: Theme parsing error: gtk.css:597:14: not a number (melt:2459): Gtk-WARNING **: Theme parsing error: gtk.css:597:14: Expected a string.

Nothing: don't crash, but text on black background (no video). . starting export at beginning of a cut, or one frame latter: crash. Starting export 2, 3, 4, 5, 6, 7, 8, 9 frame latter: don't crash. . deleting first .dv clip starting video track from timeline: export don't crash, keeping this first .dv clip: export crash. Note: exporting zone doesn't contain any .dv clip, only one .MP4 clip. The status: crash / don't crash is always very reproducible, but depends of a large set of conditions... and I cannot really find a logic inside! (Probably there is none). ![]() Any idea to help me making other tests to identify root problem? ![]() Kdenlive Version 16.12.3 MLT version 6.4.1, FFmpeg libraries KDE Frameworks 5.31.0 Qt 5.7.1 (built against 5.7.1) The xcb windowing system UbuntuStudio 17.04 amd64. |
