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 :contentReference[oaicite:0]{index=0} ...
