Bug ID: 478820
Summary: With reference audio subject to speed change, align to
reference gives wrong results.
Classification: Applications
Product: kdenlive
Version: 23.08.4
Platform: Ubuntu
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Effects & Transitions

SUMMARY
***

symbols.

STEPS TO REPRODUCE
1. Import a video+audio clip recorded at 4x speed
2. Use "change speed" to speed up the clip 400% so it plays back at normal
speed
3. Import an audio-only clip recorded at normal speed
4. Drag both clips to different tracks on the timeline
5. Select the sped-up audio as reference
6. Align the normal-speed audio to reference
7. Notice that the alignment is wildly incorrect.
OBSERVED RESULT
Alignment of normal-speed audio to slo-mo audio sped up to normal speed is
entirely wrong.
EXPECTED RESULT
Normal-speed audio aligns correctly to reference audio which is slo-mo audio
sped up to match normal speed.
