From video could not find framerate as suggested in 2.5.4 youyube tutorial

[Jan Gruuthuse]

Frame rate can usually be found in: Video Output: Selected encoding not [Copy]. [Filters] -> Transform -> Available Filters ->
- Change FPS
- Resample FPS
If that was not what you're looking for, be more specific. 2.5.4 is way out of date.
