Transition length was 0.5 seconds.\r\nMy video consists of photos for the first 30 seconds, followed by a few minutes of vids. After editing all the photos with all sorts of cool zooming and panning (thanks to the really cool bezier curves), and applying the audio cross fades on the video clips and then exporting as mp4, each clip's audio fades out about 4 seconds before the transition to the next clip.\r\nNow, I have selected clips and dragged them left or right at some stage while inserting and deleting photos in that 1st 30 second block. What I can't be sure of is that the net result of shifting those clips after applying the audio cross fades, is a -4 second shift and for whatever reason the renderer was using outdated keyframe locations to fade the audio. Further evidence is that the audio for the second clip starts abruptly, without fade-in, suggesting the entire cross-fade was shifted left by 4 seconds and the fade-in of the second clip was hidden behind the last 3 or 4 seconds of the first clip before the beginning of the second clip.\r\nWhen using preview the audio fades correctly at the transition. Shifting clips left and right also brings the keyframes along correctly. Just wondering if it's possible that the original keyframe locations are stored and incorrectly referenced by the renderer when exporting.\r\nIs this similar enough to the description of the OP or does it warrant a separate bug report?"}}
