[Kdenlive-devel] keyframable vs not keyframable

[John T. Mertz]

I don't have kdenlive loaded up atm but in most editing apps keyframes
always start as 'optional'. (Except for transitions, of course)

I.e. If you change settings for an effect's property, it changes that
value for the duration of the clip the effect is applied to. Only
after the user adds two or more leyframes does the effect actually
become animated. If only one keyframe is added then the settings for
that keyframe are used for the entire clip.

I'm not sure if this workflow is possible with kdenlive but this is
what would be ideal.
