My setup:
Kdenlive Version 19.12.2
Using: MLT version 6.19.0
KDE Frameworks 5.66.0
Qt 5.14.0 (built against 5.14.0)
The windows windowing system
Windows 10
I think I'm seeing this too. Whenever I render something, the output video is
way longer than I expect. The output video has all of my expected content, but
also a very long segment of black nothingness at the end that I don't want.
This happens both when I select "Full project" or if I select "Selected zone"
in the "Rendering - Kdenlive" (after stretching the selected zone blue bar
thing in the timeline to cover the content part of the timeline).
To reproduce:
1. Start a new project (e.g. HD 720p 23.98 fps)
2. Drag a video from your filesystem into the project bin (e.g. a 32-second mp4
video file.)
3. Drag the clip from the project bin into the timeline.
4. Render. (The settings probably don't matter, but I have it set to MP4,
quality: video = 30, audio = 192, Full project, More options > Encoder speed >
the highest/rightmost setting, More options > Threads > 1)
Observations:
1. This takes way longer to render than I'd expect of a short 32-second clip (4
minutes 30 seconds).
2. The output video is 21 minutes 23 seconds long.
3. The output video contains the 32-second video content, followed by 20
minutes 51 seconds of blackness.
4. If I open the kdenlive save file, I notice there's a line of text with
"<producer id="black_track" in="00:00:00.000" out="00:21:23.315">", which
happens to be exactly the same length as the erroneously long output video.
Additional note:
I have older kdenlive save files that I created with an earlier version of
Kdenlive, version 19.08.1. These save files also have a "black_track" producer
on the order of 20-some minutes. But they rendered just fine back with the
older version of Kdenlive. But when I open up these same save files with
v19.12.2 and render, the output is erroneously long, with the overly lengthy
black frames at the end.
So, did something change about the rendering process? Behaviour-wise, I'd
expect the renderer to truncate the output after the end of the last clip on
the timeline, so that you don't have long empty stretches of black frames at
the end of the video.
