SUMMARY When you render a project and enable "Export metadata" (after ticking "More options" in the "Rendering" dialogue and if your project title consists of multiple words separated by a space, only the first word will be written to the metadata of the file. STEPS TO REPRODUCE 1. Create a project with the title "Example title" 2. When you render the project click on "More options" > "Export metadata" 3. I'm not sure if it is important but I'm using a custom preset using mp4 container and libx264 4. Render the project 5. Inspect the rendered file with exiftool OBSERVED RESULT The title will be "Example" EXPECTED RESULT The title should be "Example title" SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch Linux KDE Plasma Version: 5.25.4 KDE Frameworks Version: 5.97.0 Qt Version: 5.15.5 ADDITIONAL INFORMATION Most likely the generated command should quote the project title. The generated command looks like this: > [...] meta.attr.title.markup=Example title I assume it might be fixed if it looks like this: > [...] meta.attr.title.markup='Example title'
Confirmed on latest master, although the fix seems to be a little more involved than wrapping the strings. The .mlt file passed to the renderer loses the words after the space in the <consumer /> tag.
I think inserting the metadata into the generated XML for MLT directly instead of first storing it in the parameters is the right way to go, because the parameter names (e.g. "meta.attr.title.markup") are MLT-specific and not related or directly useful for ffmpeg. Thus, I don't see this making the UI worse or less useful for advanced users. Changing the parameters to be a QStringList or similar should be a future improvement to whitespace-proof the parameters.

Put metadata directly in XML from doc Putting the project metadata in the parameters text hit an issue with whitespace in the metadata. Skipping the parameters text and putting it directly in the XML preserves the whitespace.
