Until now last frame was always created in the format of enabled
formatted_time but that is disabled by default.
If smartcut is enabled GUI froze at 66 % of conversion and console has:
vidcutter.libs.videoservice - INFO - /usr/bin/ffprobe -hide_banner -v error -show_packets -select_streams v -show_entries packet=pts_time,flags -of csv ".../filename.mp4"
root - CRITICAL - File ".../vidcutter/vidcutter/videocutter.py", line 1363, in saveMedia

File ".../vidcutter/vidcutter/libs/videoservice.py", line 331, in smartcut
bisections = self.getGOPbisections(source, start, end)
File ".../vidcutter/vidcutter/libs/videoservice.py", line 590, in getGOPbisections
end_pos = bisect_left(keyframes, end)
root - CRITICAL - <class 'TypeError'>: '<' not supported between instances of 'str' and 'float'
Might relate to #182.
In the case of failed video codec detection GUI freezes and console has following:
vidcutter.libs.videoservice - INFO - /usr/bin/ffmpeg -hide_banner -i "/tmp/vidcutter/foo_middle_00.mp4"
root - CRITICAL - File ".../vidcutter/vidcutter/libs/videoservice.py", line 418, in smartcheck
self.smartjoin(index)
File ".../vidcutter/vidcutter/libs/videoservice.py", line 440, in smartjoin
if self.isMPEGcodec(joinlist[1]):
File ".../vidcutter/vidcutter/libs/videoservice.py", line 608, in isMPEGcodec
codec = self.codecs(source)[0].lower()
File ".../vidcutter/vidcutter/libs/videoservice.py", line 267, in codecs
vcodec = re.search(r'Stream.*Video:\s(\w+)', result).group(1)
root - CRITICAL - <class 'AttributeError'>: 'NoneType' object has no attribute 'group'
Fixes #171
This could happen if the cut starts at the beginning of the file.
Following is found in console log:
vidcutter.libs.videoservice - INFO - smartcut files are MPEG based so join via MPEG-TS
vidcutter.libs.videoservice - ERROR - Exception during MPEG-TS join
Traceback (most recent call last):

File ".../vidcutter/lib64/python3.6/posixpath.py", line 156, in dirname
p = os.fspath(p)
root - CRITICAL - <class 'TypeError'>: expected str, bytes or os.PathLike object, not NoneType
If SmartCut is enabled GUI froze at 20 % of conversion and console has:
vidcutter.libs.videoservice - INFO - SmartCut progress: {'middle': True, 'end': False}
vidcutter.libs.videoservice - INFO - SmartCut resulted in zero length file, trying again without all stream mapping
vidcutter.libs.videoservice - INFO - SmartCut progress: {'middle': True, 'end': False}
vidcutter.libs.videoservice - INFO - SmartCut resulted in zero length file, trying again without all stream mapping

self.smartcut_jobs[index].procs[name].started.disconnect()
root - CRITICAL - <class 'TypeError'>: disconnect() failed between 'started' and all its connections
This makes conversion to fail and GUI to respond again. Error is still logged
and user is advised to turn off SmartCut.

There was a problem hiding this comment.
I have to say, qtime2delta() — which I realize you didn't write, of course — strikes me as kind of pointless. Not just here, but everywhere.
It doesn't even return an actual timedelta... it just creates one, stuffs some values into it, and then converts it to a microsecond-resolution float. (Even though the data is only at millisecond resolution, really.)
QTime has QTime::msecSinceStartOfDay that can accomplish exactly the same thing, if the result is divided by 1000.
I mean, heck, delta2QTime basically does exactly that in reverse:
