I am trying out multiple video editors on Fedora, with very poor results and a ton of crashes.  
Anyone have recommendations on how to stablize one of these or can you recommend a
video editor that just works (like kdenlive used to when I used it last a year ago)?

I am having the same results on two Fedora 25, 64-bit systems, fully updated.  The packages
are from rpmfusion and on one of the two systems from unitedrpms.  My main system is an 
older 6-core AMD with 8G of RAM so it should handle it.

The files I am testing with are:
  JPG images from a DSLR
  Quicktime from my DSLR (MVI_xxx.MOV), 
  Movie from my Android phone xxxxxxxxx.m2ts
  Movie from a DVD xxx.mpg
  Movie from a digital camcorder (Sony AVCHD):   xxxx.MTS

KDENLIVE:
My goto editor was Kdenlive, but it won't open files.  I keep getting "clip is invalid".
The terminal outputs:

mlt_repository_init: failed to dlopen /usr/lib64/mlt/libmltavformat.so
  (/lib64/libavdevice.so.57: symbol av_buffersink_get_sample_aspect_ratio, version LIBAVFILTER_6 not defined in file libavfilter.so.6 with link time reference)

I think there is a lib miss-match.

PITIVI:  
Pitivi is nice, but I can't keep it running.  Multiple core dumps.

OPENSHOT:

I really love OpenShot.  I tried the one from rpmfusion and it crashed all the time, 
for example when trying transitions.  I also tried the latest version via AppImage:

  OpenShot-v2.3.3-x86_64.AppImage 

This seemed much more stable, but I could still crash it with transitions, adding
an MP3 file for audio, etc.

Anyone have a good, stable video editor or have suggestions on how to run one of these
in a stable platform?

Note, I am filing bug reports on many of these crashes....

Thanks,
