            Bug ID: 421565
           Summary: WARNING – DANGEROUS : kdenlive creates broken archive
                    files
           Product: kdenlive
           Version: 20.04.0
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: grave
          Priority: NOR
         Component: User Interface
          Assignee: j...@kdenlive.org
          Reporter: had...@danisch.de
  Target Milestone: ---

Hi, 

just experienced with both AppImages 19.12.3 and 20.04.0b running on Ubuntu
18.04:

If a video project contains large video clips, kdenlive silently creates broken
unreadable archive files, when using the archive function and selecting to
generate a compressed archive file (.tar.gz). 

I've just used kdenlive to create a video from recordings made with a
professional video recorder, where video files (mp4) have sizes between 8 and
13 GByte.

When using the archive function from kdenlive, kdenlive creates a tar.gz file
and reports success, no problems, but then the generated archive files are
unreadable by kdenlive itself. 

Even the regular tar command line tool can't read them. When trying to tar ztf
FILENAME, it lists the contained files until the huge files come, and then
aborts with 

...
videos/Aufnahme1.mp4
tar: Skipping to next header
tar: Exiting with failure status due to previous errors

It's not related to the gzip compression, it's a problem of the tar archive
itself.

Maybe this is related to the fact that the older/original versions of tar file
formats had a file size limit of 8GB and could not handle larger files. 

However, this is extremely dangerous, since it does not just crash kdenlive or
create bad videos, it can cause the loss of the raw files, the sources.
