Sequencer render to video is a V2Editor TimelineVisualizer export surface for queueing a validated sequence render as MP4 or MOV with configurable resolution, framerate, frame range, warmup, overwrite, and audio mixdown options.

Runtime API#

  • Panel spec: FV2SequencerRenderVideoPanelSpec
  • Preset: FV2SequencerRenderVideoPresetSpec
  • Request: FV2SequencerRenderVideoRequest
  • Job: FV2SequencerRenderVideoJob
  • Result: FV2SequencerRenderVideoResult
  • Format enum: EV2SequencerRenderVideoFormat
  • Issue enum: EV2SequencerRenderVideoIssueType

QueueSequencerRenderVideoExport accepts the current sequence, panel spec, export presets, and request. It validates the sequence camera track, output path, format, resolution, framerate, and frame range, then returns a queued Movie Render Pipeline job with deterministic output file path and size/duration estimates.

Behavior#

  • The panel targets TimelineVisualizer, supports MP4 and MOV, and exposes resolution/framerate overrides.
  • Default presets include RenderVideo.Preset.MP4.1080p60 using H264.MP4 and RenderVideo.Preset.MOV.4K24 using ProRes.MOV.
  • Requests provide an export id, output directory, file name stem, format, resolution, framerate, frame range, warmup frames, audio mixdown, overwrite behavior, and output format.
  • Output paths are generated from the requested directory, file name stem, and format extension.
  • Exports require at least one camera track with a binding id.
  • Results expose the queued job, output path, total frames, estimated duration, estimated size, Movie Render Pipeline queue state, audio mixdown state, and overwrite state.

QA Inventory#

  • Panel: verify MP4/MOV support, resolution override, framerate override, Movie Render Pipeline use, supported formats, and progress state.
  • Presets: verify MP4 and MOV presets validate with matching codecs/extensions.
  • MP4: verify 1080p60 export queues and writes an .mp4 output path.
  • MOV: verify 4K24 export queues and writes a .mov output path.
  • Options: verify audio mixdown can be omitted and overwrite state is preserved.
  • Off-path: reject missing camera tracks, unsupported format surfaces, resolutions above panel max, invalid framerates, missing output paths, and frame ranges beyond sequence duration.

js_repl Playwright interaction was unavailable in this session and the affected surface is Unreal editor data rather than browser-rendered UI, so verification is through UE editor automation and contract gates.
