Description:
Create a new project and add several clips to the timeline (seamless).
Export the complete project and export it clip-by-clip.
Concatenate the clip-by-clip version using ffmpeg (ffmpeg -f concat -i <fileslist.txt> -c copy <concatenated.mp4>).
Compare the complete project-render and the concatenated one: the latter one is shorter, missing exactly one frame per clip (you can also compare the length of the rendered clips and the original ones it you use them completely).

Reason why this is a bug:
This behaviour is problematic if you render your project's video split in several parts (e.g. to because of render time or memory usage) and merge it with the project's audio afterwards, with the audio rendered completely in one step.

Please try with the Kdenlive_Nightly_Appimage
https://binary-factory.kde.org/job/Kdenlive_Nightly_Appimage_Build/lastSuccessfulBuild/artifact/

Would be interesting to know if this is solved.

It seems that this report is related to a very old unmaintained version. Please test with the latest version (20.12.3 at the moment, https://kdenlive.org/en/download/) and close this report if it is not relevant anymore.
