Just a guess change the 44.1kHz to 16bit in Ardour and try again. Exported from Ardour audio track with 16 Bit, 44.1 kHz. To simplify the situation removed from the project video and left only audio with 16 Bit, 44.1 kHz and normal clips titles made in kdenlive. Render-all the same as before the changes. It's useless. Added to issue#12 https://invent.kde.org/kde/kdenlive/issues/12 Kdenlive 19.12.3-appimage on UbuntuStudio 19. ะhe same problem still happens. Constantly, in each project I shift the track with the music exactly 8 frames to the right, then on the rendered video the synchronization becomes good. Usually this desync is not noticeable until it comes to the end credits, where they should go rhythmically with the music. Stupid question: Do you have as local decimal separator a comma? If so change the OS setting local decimal separator to dot. Try again. (In reply to emohr from comment #6) > Stupid question: Do you have as local decimal separator a comma? If so > change the OS setting local decimal separator to dot. Try again. Yes, decimal separator - is comma. Was try change separator to dot - all the same. I forgot to point out that unlike the author of the post, I have a linear desynchronization. This should be fixed with a fix in MLT. Please try with the current Kdenlive AppImage version 20.12.2 https://download.kde.org/stable/kdenlive/20.12/linux/ (In reply to emohr from comment #8) I tried it. Unfortunately, nothing has changed. Although no, to be precise, it has changed a little: if earlier I shifted the audio track for perfect synchronization by 8 frames to the right, now, I do it by 4 frames.
