unwanted conversion to 600fps

Description

Blender Version
Broken: 2.8
when rendering out videos in the video editor it outputs them as 600fps

if you upload a video into the video sequencer and set the framerate for 23.98 it outputs as 600fps. This can be seen by putting the rendered video back into the sequencer or checking the properties of the video itself.

There was a similar fix a while ago.

What export setting are you using? Can you share a .blend?

I can share the .blend file along with the video I was trying to edit

Christopher_Anderssarian raised the priority of this task from Needs Information from User to Waiting for Developer to Reproduce.

Thanks, I'll check later today...

This seems to be similar to T53687: VSE Detecting and setting incorrect frame rate (further reading here: T53857)
but (in this example) does happen with AVI and speed control. It works in 2.79b, but fails in 2.8...

@Richard Antalik (ISS) not sure if you want to dig in to this or not...

Additional information from another affected user:

Is there a workaround for this, some different setting I can try?

Here's a fix using ffmpeg:

ffmpeg -i input_600fps.avi -codec copy -r 30 output_30fps.avi
