at the same speed of 1x
Product: kdenlive
Version: 21.08.1

clip monitor at 1.5x playback
SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug
symbols.
See
https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***
I downloaded and installed the binary installer.
MLT version 7.1.0
STEPS TO REPRODUCE
1. Create a new project, and add a video clip (here it is of MP4 format).
drag the newly-added video clip to the tracks area.
2. click the clip monitor. Click the cursor in the timeline bar above the
buttons.
3. click the forward button twice, and 1.5x is shown at the upper left corner
in the monitor.
However, the playback speed is actually 1x. I timed with a stopwatch app (on
mobile phone), and compared with the timestamp shown to the right of the
forward button.
4. click the cursor in the timeline bar above the tracks.
click the forward button twice, and 1.5x is shown at the upper left corner in
the monitor.
Playback speed is actually 1x.
OBSERVED RESULT
1x playback speed.
EXPECTED RESULT
1.5x playback speed.
When I click the forward button one more time, and 2x is shown and the playback
speed is actually 2x.
So the 1.5x playback speed cannot be achieved.
