ADDITIONAL INFORMATION
When I start editing in Kdenlive all appears to be ok until I start cutting clips, the Video and Audio become way out of sync on the clips which have had no edits. Not sure if I can reproduce It's something that I keep noticing once I get very involved in the editing process.

Wanted to add an update to my first bug report, I'm incorrect in saying that the audio and video sync are out, It's actually the audio and waveform that are out of sync.
My apologies for this misinterpreted information, I feel like I may have wasted somebody's valuable time.

Are Video/Audio couple going out of sync or a separate added audio file is going out of sync relatively to the video? Do you notice the out of sync during playback the timeline or after rendering?

Comment 3 Colin Brash 2019-09-21 02:14:24 UTC

Audio and Video are the same, eg: adding a single video file to the timeline and the Video/Audio are separated as expected in Kdenlive, I believe the problem occurs as you start cutting out sections of the Video/Audio (In my example the Video/Audio sections are cut equally the same, ("No Cutting" of different sections of Video and different sections of Audio) I believe the Audio is in sync with the video, however it's incredibly difficult to select an Audio section as the Waveform is way out of sync, eg: where you have a gap in the waveform there will be sound, where there is a waveform showing sound there is no sound, it's out of sync randomly, I hope this makes sense, thanks for your response, it's much appreciated!!

Seems related or duplicate of bug #423337.
