Is there a way to make a clip smoothly transition over a range of speeds?

When trying to slow down a particular interval, jumping from one speed to another looks jarring. I suppose one could cut the clip and manually create a gradient but it would be nice if there was a tool to automatically do this instead.

You can try using slowMoVideo and then pull the new output clip into Shotcut:
