Video is a good idea f0r some "collecting" and all smart phones have video. Even some less savvy phones! It does need some sort of video editing software, and consumes far more storage than audio. Horses for courses.

But as I used to say when dumbclucks pointed to the quality of recordings with my micro cassette pocket memo.
"And just what is the quality of a recording you didn't make?"
Small and ever ready! And excellent for songwriting.
