What ever the current official build is, currently an “.A” release i think. Meaning big bugs have been fixed. However I personally live on the bleeding edge with daily builds from the Blender build bot. There are just to many goodies for me to resist.
I will admit though that when making Dream Big I stuck with one build through the job.
You might want to consider using the vse transform addon. It lets you use all the standard grab scale and rotate functions from 3d view but on video strips.
I may use the Animation tools first then VSE later.
There are no video’s on the VSE at this time.
I see there is more than one way of doing something.
I will have to learn as many as I can.
