Add new filter: Shake

Pls add shake filter, like in Premiere, with lots of customisation!

Please check and try the great amount of videofilters in Shotcut, eg. ‘Nervous’.
Remember that filternames are not equal to other video editors in SC.

The size and position filter has a preset for this. If you need more than 1 second, see how the preset creates keyframes and add more if your own.

Thanks
