SUMMARY STEPS TO REPRODUCE 1. add a video clip to timeline (v1+a1) 2. add a second clip to timeline on a2 only 3. move time line to pos1 4. start play on the project 5. move the timeline pointer to another position OBSERVED RESULT This stops the play (ok) now restart the play the video starts at the timeline pointer BUT the audio tracks starts again at the point it stopped previously, not at the point you choose in the timeline. EXPECTED RESULT when moving the timeline pointer somewhere and restarting the project player, I expect the play to start at the timeline I specified for all the tracks.
In fact it is only the second audio track which is not responding to timeline pointer selection, the first one (part of the first clip) is ok.
Correct description STEPS TO REPRODUCE 1. add a video clip to timeline (v1+a1) 2. add a second clip to timeline on a2 (it has only audio) 3. move time line to pos1 4. start play on the project 5. move the timeline pointer to another position OBSERVED RESULT This stops the play (ok) now restart the play the v1 and A1 start at the timeline pointer specified BUT the A2 audio track restarts at the point it stopped previously, not at the point you choose in the timeline. EXPECTED RESULT when moving the timeline pointer somewhere and restarting the project player, I expect the play to start at the timeline I specified for all the tracks.
I tested with 20.08.3 and it works as expected. Please try with the current Kdenlive AppImage version 20.08.3b to see if there are any packaging issues https://download.kde.org/stable/kdenlive/20.08/linux/ If the problem/issue doesn't occur when using the AppImage, then it's your configuration or packaging.
I tried with appimage and obtained the same result. Maybe I don't explain correctly. 1. get a videoclip and put it on the timeline => v1+A1 2. separate v1+a1 3. get an audio clip and put it on timeline => A2 4. put the timeline cursor somewhere and start playing the project 5. stop the play 6. mute A1 7. start project play, you should hear A2 only while video V1 also plays 8. stop in the middle of a sentence you can recognize on A2 9. now put the timeline cursor somewhere else the play stops. now if you restart the project play you should hear A2 somewhere else, but in fact I can hear A2 as if I did not move the timeline pointer (the interrupted sentence continues although I am positionned elsewhere in the timeline) If I move the time line ANYWHERE, only the video V1 is affected, but A2 continues just where it previoulsly stopped, A2 is never repositionned according to the timeline pointer. This occurs only if you have a clip composed of video+audio and then add another audio clip. The added audio clip seems unaffected by the timeline cursor position once it has successfully played once.
my videoclip v1+a1 is webm my additionnal audio a2 is mkv
I have a more simple way to show the problem. After having done all steps 1-9 then replay, stop the play, then translate A2 track so that there is some time before track A2 begins then position timeline cursor a little before begining of track A2 start the play normally you should hear track A2 at its begining when the timeline cursor reaches it but in fact A2 sound will continue where it lastly stopped !
I tested with step 1-9 with a webm and an mkv file as you described. I can't reproduce your issue. Maybe the file type inside the container has an issue. Could you upload the file you used so I can do the test again?
The 2 files are available here : http://dl.free.fr/mKDuk8nYU
Created attachment 134201 [details] MKV_without video Thanks for the clip. I can confirm the issue. Putting the WEBM and MKV clip into the project bin and confirm 856x480 30fps. Then the clips get converted. I can reproduce the out of sync issue using the MKV clip only. Neither in the clip view nor in the timeline Kdenlive finds the correct position for the MKV clip ones you have re-position the playhead, exactly as you descript in comment #4. Workaround: with the program MKVRoolNix I saved the MKV file without the video part. Re-import this MKV file. Now the issue is gone. So it seems that an MKV containing audio only but an "empty" video stream get wrong converted.
Hi and thank you for your patience. I cannot test with Kdenlive 24.12 as your clips are not available anymore. Can you please check whether this issue still exists in the latest version 24.12.0? If yes, please update this report to reflect the new version and set the status to CONFIRMED. If it works now like you expect it would, you may change the status of this report to RESOLVED - FIXED. At any rate, this report will be closed if there is no activity for the next 30 days.
