If by "aid" you mean the video, well, the Pali Canon (the oldest known buddhist meditation writings) talk about kasinas, which are visual meditation objects, though they're not especially popular these days.
And of the "Three Jewels" that support buddhist practice, one is the sangha, which can be translated as community, so it's not always true that meditation should be a solitary practice either..
I think guided meditations like this may be useful for beginners, though that being said, I think no stimuli may be better in the long-run than even soothing stimuli.
