does dropped frame rate depend on the source film ??

[DaveQB]

my dropped frame rate for my 50minutes captures i am doing varies from 30 to 400

i am wondering if this is all based on the film i am capturing?

i noticed on one tape that there is a guaranteed drop frame right at the start when the camera flickered on.
i captured that tape 2-3 times now and every single time 1 dropped frame is amassed at the start.

i am still yet to achieve 0 dropped frames yet, but am wondering if home video that was recorded in 5-10 second on/offs would effect the dropped frame rate.

doesnt seem to lend to bad quality though
