Compress the Videos, Not the Construction Loop
TL;DR for operators A much smaller video training set is useful only if creating it does not become another expensive optimization job. ProtoBlend targets that second cost: after preparing and running a teacher model, it constructs the compact set directly instead of repeatedly optimizing stored synthetic videos. On MiniUCF, its reported post-teacher construction time stays below one hour at both one and five videos per class and changes only slightly as the storage budget grows because cached teacher outputs are reused.1 ...
