Bug - Create Video from Still Images Image display time rounds decimal values

[muge]

As the title says, the "Images display time" rounds decimal values that are input (0.033333 becomes 0, 1.7 becomes 2) in the UI once the control is unselected/defocused. This happens in both the dialogs accessed from the Wizard and from Join Files.

The control is set to accept only natural input, not decimal. That is not an error, it is just that such precission is not considered necessary is the main purpose of creating a quick image slideshow.

My use case for this is basically combining a sequence of individual images as frames to make a video, so this level of precision would be key to have when the animation is at 24/30/60 FPS, for example. While the intention for this may be for slower image slideshows, this functionality does double for combining individual frames to form animation once it can be controlled more precisely.

Ideally one would be able to specify the frame rate of the image sequence itself, should I change this to be a feature request then?

Can you provide an ffmpeg command line example of what you would like to achieve?

[muge]

I am not well-versed in ffmpeg usage, but here's a bare-bones example:
ffmpeg -r 60 -i animation.%03d.png -vf format=yuv420p outputfilename.mp4
Essentially, set the frame rate of sequence to 60 FPS, input sequence of png files matched here w/ regex, set format, outputfilename.
Ideally -i animation.%03d.png instead matches the sequence of files/images imported into the batch processing file queue... sometimes there's a need to skip certain frames or sequences in the middle of a long one so coming up with a regex match would be pretty complex and not time-efficient vs just dragging and dropping the required frames in.
Hope what I'm saying makes sense!
