I tried again with a PNG color clip instead of the built-in type. This did the same. I then rendered a video clip with the same color and inserted it into the project. This did not exhibit the effect. Some more stuff that seems related to the reported bug. I want to display a sequence of images over a video background. I usually alternate the images in 2 tracks above the video, with the first and last images longer than the rest. Now, if I do this then save, when reloading the images are all moved and made the same length. I can make do by putting them all in the same track, but the first image still gets shortened and the whole lot shifted. I have to render this part separately and put it into the main project but I have no way to save the project file so it will load again. This is long before all the other things I usually do, like overlapping and crossfading the images, none of which is currently possible. Was not able to reproduce this in 21.12.3 (AppImage) so seems like it's been fixed. Commit 0492874aa seems related. |
Created attachment 143963 [details] Illustration of problem SUMMARY STEPS TO REPRODUCE 1. Create new project and import a video/audio clip. I have tested with 720p and 4k. 2. Place a color clip (I used white) at 2 seconds (default 5 sec length) into track V1. 3. Place the video/audio clip into track V1/A1 at 10 seconds. It should appear as in the top part of the attached image. 4. Save, exit and reload the project. 5 Edit the color clip to extend it to the video clip, covering the 3-second gap, as in the middle part of the image. 6. Save again as a different project name, exit and reload the project. OBSERVED RESULT The video has become detached from its audio and moved to where the color clip previously ended. See the lower part of the attached image. EXPECTED RESULT The project should load in the state in which it was saved. SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE Neon 5.23 KDE Plasma Version: 5.23.3 KDE Frameworks Version: 5.88.0 Qt Version: 5.15.3 ADDITIONAL INFORMATION Processors: 8 x Intel Core-i5 8250U @ 1.6Ghz Memory: 16G OBSERVATIONS 1. If I replace the color clip with a title clip the effect does not occur. 2. This is a recent problem as I have been using color clips in projects for several years. The problem started a few weeks ago when I was trying build a slide show to run over a video, placing a color clip under the video to fade it partially to white. The procedure here is the simplest I can reduce it to. Here are the 2 project files. Kompare shows a number of differences but the problem seems to appear in lines 431-436. <?xml version='1.0' encoding='utf-8'?> <mlt LC_NUMERIC="C" producer="main_bin" version="7.1.0"
