Brandon ThomasandClaude Opus 5.5 b26fbb6247 M10.2: VP9 inter frames (motion search, MV prediction, loop filter, forward probability updates, rate control)
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.

Brandon ThomasandClaude Opus 5.5 406706e3d5 OUT-2: WebM export (VP9 intra encoder + alpha, Opus), WAV/AIFF audio-only outputs
- effectcraft-vp9enc (L0): VP9 profile 0 key-frame encoder from the VP9 bitstream spec
  (8x8 intra blocks, DC/V/H/TM, 4x4 DCT/ADST, lossless WHT at quality 100, tile columns);
  round-trips exactly through FilmCraft's VP9 decoder and ffmpeg.
- export: WebM muxer (EBML/Matroska spec) with VP9, VP9 alpha in BlockAdditional
  (AlphaMode 1), Opus (CodecDelay = pre-skip); WAV and AIFF outputs.
- OutputFormat WebM/Wav/Aiff in the Render Queue, renderQueue.add formats, CLI --format.
- Tests: FilmCraft decode-back (frames, size, pixels, audio RMS), ffprobe/ffmpeg oracles.
