Bug ID: 439658
Summary: Align to Audio Reference sometimes is off.
Product: kdenlive
Version: 21.04.3
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Effects & Transitions
Assignee: vpi...@kde.org
Reporter: bi...@ivdc.com
Target Milestone: ---
While aligning a external audio clip to a video with embedded audio, it
sometimes can be off by a frame or two. (or half a frame). I just edited a
video and didn't bother to listen to the in-video audio track vs my separately
recorded audio track and found lip sync issues after render (didn't really
notice them with proxy clips and 540p video in the preview monitor). When I
turned on the embedded audio track, and played both audio clips together, It
produced a echo. Manually adjusting the audio clip back/forward by 1 or 2
frames typically fixed it. Although, being able to adjust by 1/4 or 1/2 a frame
would prove useful too as it still had a hint of a echo on one clip.
This didn't happen with every clip. Also, I use a Clap board with all my takes
as well, so, shouldn't be ambiguous.
Additional info: Files are .MOV files including the audio only (which appear as
full video but, I just ungroup and delete the video channel)
Hardware: iPhone 12 Pro MAX and iPhone 8 for Camera's, iPad Air (Gen 3) as the
audio recorder with a RODE GO II Wireless mic. 1080p 30fps.
