Currently the only way to speed up video over 400% is with velocity envelopes. Wondering if we can implement a higher percentage of you basic ramp with the simple ctrl+drag. The use of velocity envelopes induces looping and requires additional steps/editing.
Workaround is to save the 400% speeded up event as a project and use that as a nested project. This nested project can be speeded up by dragging again to max 400%, which is than 1600% of total speed up.
