| Good question! Several reasons: * Video codecs are much more complex. * Random access seek is a lot slower, unless you're using all I-frames. (That's now a codec option on iOS, but not when I started.) * "Studio swing" reduces the dynamic range of the YCbCr components so the quality suffers. * Each frame lacks their own thumbnail, unless you maintain an adjunct "thumbnail video" * Each frame might(?) not be able to have attached separate metadata, like geotagging, sensor settings at time of capture, etc. * Deleting one frame causes a "hole" and headache. * Standards compliant JPEG means export is super easy. * Anything above full HD video is difficult to deal with in 3rd party software. |
