effectcraft-vp9enc gains inter frames: single LAST reference, 16x16/8x8 blocks, candidate + diamond search refined to quarter samples with the regular 8-tap filters, NEARESTMV/NEARMV/ZEROMV/NEWMV with spec MV prediction, skip blocks, the in-loop deblocking filter, per-frame forward probability updates, a key frame interval and target-bitrate rate control. Decoded output matches the encoder's reconstruction exactly through FilmCraft's decoder and ffmpeg. WebM export now encodes sequentially with a key frame every two seconds.
