--- Comment #3 from Robert <rob...@robertelder.org> --- Hi Jean, I followed your suggestion and I can confirm that your expectations are correct: Renaming the file to not have a colon character seems to make this problem go away. Here are the steps that I followed: mkdir /tmp/test1 cd /tmp/test1 wget https://files.kde.org/kdenlive/release/kdenlive-19.04.3-x86_64.appimage chmod u+x kdenlive-19.04.3-x86_64.appimage mkdir project1 cd project1 wget "http://www.robertelder.ca/Screencast 2019-06-08 13:53:57.mp4" mv "Screencast 2019-06-08 13:53:57.mp4" foo.mp4 /tmp/test1/kdenlive-19.04.3-x86_64.appimage # Now create a project, add the clip foo.mp4 to timeline. Render to output file '/tmp/good.mp4'. # Save project as /tmp/test1/project1/project1.kdenlive # Exit program. # Check /tmp/test1/project1/project1.kdenlive and note that the project file uses relative paths for the video file (which is probably the right way to do it). cd /tmp/test1/ mkdir otherdir cd otherdir /tmp/test1/kdenlive-19.04.3-x86_64.appimage /tmp/test1/project1/project1.kdenlive # Render project to output file '/tmp/bad.mp4'. Result: md5sum good.mp4 bad.mp4 81d03f1cd0983059598ee61ff06683fd good.mp4 81d03f1cd0983059598ee61ff06683fd bad.mp4 Both files play the video correctly. -- You are receiving this mail because: You are watching all bug changes.
