Many thanks for your reply, and for pointing out the existence of the
tmix filter. Please forgive my ignorance about it. I see tmix was only
added in April this year, whilst I've been carrying skipblend (and
tried getting it upstreamed a few times) since June 2017. No matter,
it's great to see this sort of functionality finally included!
Would you consider accepting a patch that added an integer "cutoff"
option to tmix, for the purpose of setting all weights for frames
beyond "cutoff" to 0? The reason for requesting this is that in some
workflows, one is blending together a lot of frames at once, and
specifying a vector of, say, 100 ones followed by a zero, when
blending together, say, 200 frames, whilst possible, is rather
tedious; for instance "tmix=frames=200:cutoff=100" (weights are 1 by
default so this should then work as expected).
