- Add parametersExpanded field to 5 generation node data types (NanoBanana, GenerateVideo, Generate3D, GenerateAudio, LLMGenerate)
- Create useInlineParameters hook for localStorage-backed global setting (default: false)
- Create InlineParameterPanel component with collapsible UI and chevron toggle
- All TypeScript compiles without new errors
- Track created blob URL in async chain with createdUrl variable
- Cleanup function revokes orphaned URLs created after cancel flag set
- Remove unnecessary prevInputRef deduplication (React handles this)
- Fixes race where rapid videoUrl changes orphan blob URLs in memory
Data URLs force Chrome to re-parse base64 on each access. With autoPlay
loop, this happens continuously and can freeze the main thread on systems
with weak GPUs that fall back to software video decoding.
Add useVideoBlobUrl hook that converts data URLs to blob URLs via
fetch->blob->createObjectURL. Returns the data URL immediately as
fallback to avoid flicker, then swaps to blob URL once ready (~50ms).
Properly revokes blob URLs on input change and unmount.
Applied to all 6 <video> elements across 5 components:
- GenerateVideoNode (outputVideo)
- VideoStitchNode (outputVideo)
- OutputNode (contentSrc, inline + lightbox)
- EaseCurveNode (outputVideo)
- VideoTrimNode (previewUrl)
Store data is unaffected — getConnectedInputs, executors, and
imageStorage all read outputVideo from the Zustand store, not from
the rendering layer.

Audio from generateAudio was being silently dropped during video
stitching. Add [VideoStitch] checkpoint logs at each stage where
audio can be discarded: getConnectedInputs, prepareAudioAsync,
and codec detection. Surface codec failure as a visible progress
warning instead of only console.warn.

Switch AVC_LEVEL_4_0 from Baseline profile (avc1.420028) to High profile
(avc1.640028) for broader platform compatibility. Feed audio to the muxer
before video frames so packets are properly interleaved — previously all
audio was dumped after video, causing Discord to skip the audio stream.
Probe total video duration upfront to trim audio to match video length.

Cover 11 new source files with 280 specs across pure function libs,
React components, and async hook logic. Key areas: easing functions,
bezier presets, speed curve warping, video encoding config,
AudioInputNode, EaseCurveNode, CubicBezierEditor, audio mixing,
audio visualization, video stitching, and speed curve application.

After all video frames are processed (phase 1), the final video duration
is known from highestWrittenTimestamp. Audio is now trimmed to that
exact duration before being encoded into the MP4 (phase 2). Prevents
audio tracks from extending beyond the video.

When videoDuration is 0 (unknown at call time), prepareAudioAsync was
computing targetDuration as max(0.1, 0) = 0.1 seconds, truncating the
audio to 100ms. Now computes the actual decoded audio duration from
buffers and uses that when videoDuration <= 0.

Use MediaBunny as the primary decoder following the documented pattern:
getPrimaryAudioTrack() + canDecode() check + AudioBufferSink.buffers().
Falls back to Web Audio API's decodeAudioData if MediaBunny cannot parse
the format (e.g. unusual codecs). This ensures MediaBunny handles
container formats it supports while Web Audio API catches the rest.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
MediaBunny's Input/BlobSource is designed for video containers and cannot
parse standalone audio files (MP3, WAV, etc.), causing "unsupported format"
errors at getAudioTracks(). Replace with Web Audio API's decodeAudioData
which natively handles all browser-supported audio formats.
