If possible, I think the Auto Ripple function should automatically move the events when using the Trim Events to Include all Frames option. See my screen recording below to understand better.
The Trim Events to Include All Frames option is for automatically adjusting the length of events according to the frame rate.
It is mainly used to automatically adjust the length of events when using Slow Motion and Fast motion effects where the frame rate is changed to modify the speed of events.
See my screen recording below. Note that at first, when applying the velocity envelope, I didn't use the Trim Events to Include All Frames option and had to manually adjust the event length. Later, when I activated the option Trim Events to Include all Frames, the length of the event was adjusted automatically.
@xberk... In VEGAS Pro 19 this option works correctly only in the build 550. In other builds, there is a bug when using velocity envelopes. This bug was only fixed in vegas pro 20 build 326.
