Hi guys,

Spent some time on editing a 2 hours length video and then let the PC to render the output (1080 24 frames).
I have added quite a bit of title clip used for annotation across the video.
But, I found out that the title clip placement on the timeline are shifted either to earlier or later on the timeline.
I'm not too sure what is the mistake that I'm doing.
This is my 2nd video, so I'm still learning.
Any ideas would be appreciated.
Thank you.

I have managed to solve the issue.
The root cause of the issue is when a title clip was set with a duration but when later deployed on the timeline and were to be manually stretched longer or shorter, this will later mess up the rendered output video although it looks exactly fine on the timeline. It seems that the rendering process will pull the title clip as it is without considering the duration that has been modified on the timeline. With this condition, if you have several title clips (we have quite a bit for screen annotation) that has manual duration alteration on the timeline, it will rain havoc either arriving late or early in the timeline as the original duration of title clip will be used.

Anyhow, great software although I have managed to create only 2 videos so far with a total of 3 hours length.

Was a know bug ( https://invent.kde.org/multimedia/kdenl ... ssues/1231 )
Fixed on 21.08.3

I have 21.08.3 installed - in fact, because of this problem I reinstalled it from the PPA repository on Monday 15 November, but the problem persists.
My hack was to break the video down into 10 minute segments with four cuts each, but this is not a sustainable solution.

It seemed really unstable to me, and - although this is probably a separate issue? - webm export is now really poor quality. Mp4 is fine.
If I need to send more information, please help me with what to include and where to find it, thank you!

I am on Linux Mint Tricia - and I never had this problem with Kdenlive before: I was using it all of last year and love it so much - so thank you to all of the developers, maintainers, and contributors.

currently i'm using the 21.08.3 and i found that there is a bug that make audio thumbnails misplaced in time... (and i can't do multi-camera editing looking at the audio waveform to sync all tracks) but for everything else i have no issue and currently there are no issues related to differences from timeline and final rendering.

if you can find a way to (easly) reproduce... i can suggest to open a report here: https://invent.kde.org/multimedia/kdenlive/-/issues

P.S. maybe can be a starting damaged project the real issue? (if you start a new one from scratch ... can you reproduce the bug?)
