As far as I can find, vMix does not yet have a way of setting the overall playback speed used for files in the List input.

It would be desirable to be able to set this both below and above 100% speed.

In our use case, we export replay events as files to a folder, populate the List input with these files, and would like to
play these files back at 80% speed instead of 100%.

Since the files are no longer in the replay part of vMix, but in a List input, replay speed currently can be changed.

For us, it would suffice if there only is an overall speed setting, i.e. all files in the list play back at the same speed.

Please give a +1 if you support this request.
Many thanks.

Thanks doggy, hmmmm it turns out that by right-clicking on the List input,
one can indeed make a playback speed slider visible.
However, setting it at 80% (or anything else) has no effect at all.
In the list are avi files that live on a local M.2 drive.
These avi's are exports from vMix replay events.

It seems, my request is not so much for a new feature,
but for a possible bug fix.
I will get in touch with vMix support.

Thanks a lot for testing doggy.
Maybe it has to do with the vMix AVI format.

I will do some more testing.
