Bug ID: 474017
Summary: resolutions like PAL are profoundly broken: assets
need to be over-stretched in order to render
Classification: Applications
Product: kdenlive
Version: 23.08.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Video Display & Export
Assignee: j...@kdenlive.org

the 4 images described in the bug
SUMMARY
If you import a 720x576 image into a 720x576 project set at 720x576 and then
render it at 720x576 your 720x576 images inside it actually squish to
STEPS TO REPRODUCE
1. File / New / SD/DVD Widescreen / 720x576 29.97 / OK
2. Right click / add clip or folder / add 720x576.png attached below
3. Drag to timeline
4. Ctrl + Enter
5. Render as any format (we'll use GIF here because mpeg-4 has some limitations
while GIF inarguable has none)
6. Render to file
7. To eliminate any issues where mpv or anything else could be putting in bars
we convert the frames to png with imagemagick: convert untitled.GIF out%03d.png
OBSERVED RESULT
Observe that out001.png is squished with black bars - the image having been
reduced to 506 x 576.
You actually need to take your 720x576 assets, stretch them out to 16:9 and
then put them in which in this case is 1024x576.
The squished result is called "squished.png" and the overstretched result to
get the full-flush is called "properly-fit.png"
EXPECTED RESULT
720x576 assets in a 720x576 project that's rendered at 720x576 should go in at
720x576 and render at 720x576 without having to compensate by preparing them by
distorting them through elongation so that they render properly
