Summary: Kdenlive ignores milliseconds in entry position when
importing an old project file
Product: kdenlive

SUMMARY
***
Kdenlive ignores milliseconds in "in" and "out" when importing an old project
file.
I've imported a Kdenlive project from 2017 and noticed that the audio was out
of sync. I've investigated the problem and found out that Kdenlive seems to
ignore the millisecond part when converting the old frame based "in" and "out"
attributes to timestamp.
For example, the old project file declares:
<entry out="51638" producer="3_playlist2_audio" in="42914">
After importing and saving this becomes:
<entry producer="3_playlist2_audio" in="00:28:36.000" out="00:34:25.000">
Let's calculate... frame 42914 translated to 00:28:36.560 based on 25fps, and
frame 51638 to 00:34:25.520, so the audio becomes out of sync by half a second.
I also entrys where the audio was nearly one second out of sync due to this
problem.
This problem effects both audio and video entries:
Old: <entry out="49723" producer="1_video" in="36740">
New: <entry producer="1_video" in="00:24:29.000" out="00:33:08.000">
Correct timestamp of 36740 is 00:24:29.840, of 49723 is 00:33:08.920
***
STEPS TO REPRODUCE
1. Take a project file from Kdenlive 16.08.3
2. Open that file with version 21.04.3
3. Save that project
OBSERVED RESULT
Audio becomes out of sync
EXPECTED RESULT
Audio in sync
