Export freezes at 50% [could not open codec]

[Platypants]

Hi, I'm a new user. I'm running Ubuntu 18.04.2 with Vidcutter 6.0.0. When I attempt to export my cuts with "Save Media", the progress bar jumps to 50% and then freezes there. I'm forced to quit the program. I have tried this with mp4s and flvs of varying lengths with the same results. The only possible clue I see in the console window is "[vd] Could not open codec."

same issue here, closing SmartCut may fix it.

Same issue but sometimes freezing at 66% (for 2 or more clips).

This problem may be similar to report #212 (Edited Video cannot save properly)
In the case of problem #212, it does not occur if "frame accurate cutting" is not enabled.
Version: 6.0.0 - Flatpack
System: Linux Mint mate 18.3 64bit

Have the same issue.

It seems the clue is

It tries to show a dialog about Disk space and fails.
For me it happens if there is no info on free space - my video is on the mounted virtual drive.
If i try to cut the video from ordinary location, there is no any error.

I've tried to convert with this configuration and the problem still remains.
