Build the trim/setpts/tpad filter chain that aligns a clip's post-processing source stream with its scene-time window `[t_in, t_out]`. ## Why Withou

Convert into argv form with explicit final-encode quality.

Trigger a background thread that decodes raw frames and runs the full chroma-key + colour-correction + effect stack on them. Results land in `processe

Legacy scene-only undo wrapper. Kept so old call sites compile; new ones should use `undo_full` to also recover assignment maps.

Write world-pixel centre into `canvas_layouts` (preferred by `get_element_world_pos`) and keep the normalised layout track in sync.

Sample the volume at clip-local time `t_local`. When `"volume" ∈ animated_params` and `volume_kfs` has at least one keyframe, the eased keyframe value

AABB ∩ AABB test (both expressed as `(min, max)` world-pixel pairs).

Hint at which clip the inspector is currently editing the skeleton for. Returns the source-clip context for the active selection (actor or video overl

Add a new audio track at the top of the audio block.

Apply chroma-key + colour-correction + effect-stack to an RGBA8 buffer in place. Routes through `video_cache::apply_effects_cpu` / `apply_effect_stack

Apply the user's effect stack to a preview frame in declared order. Disabled / zero-intensity entries are skipped.

CPU implementation of the chroma-key + colour-correction pipeline. Mirrors what the live `apply_preview_effects` did but lives on the cache so the res

Apply a layout JSON value to the editor state. Extracted so the `.memstroy` bundle loader can reuse the same field-by-field extraction without going t

Apply a background scan result on the UI thread.

Commit a drag-and-drop / picker-driven attach: write the binding into the source element's `skeleton_attachment` field (overlays) or push into the sou

All fonts found on the system, deduplicated by family name and sorted A→Z. The first call kicks off the background scan; until the scan completes this

True when the body of the message contains the substring (case- insensitive). Useful to filter posts that carry the meme tag "Имба" — the channel's co

In-place separable box blur with radius `r` (pixels). Skipped when `r <= 0`. Alpha is blurred along with the colour so the drop-shadow edges of the pi

Format a `chromakey=...` filter snippet from a [`ChromaKeyParams`]. FFmpeg's `chromakey` filter requires `similarity ∈ [1e-5, 1]` — passing zero or a

Remove layout keyframes that only existed for `param_id`, then flatten the parameter to a constant on every surviving keyframe.

Compact human-readable label for a clip (used by the drag preview).

Snapshot the current contents of the drained stderr buffer for inclusion in error messages. Returns the LAST few non-empty lines, since FFmpeg prints

Collect animated parameters from an element's effect stack and append them to the param list using the `fx_{idx}_{sub}` naming convention. Only effect

Push the painted shape onto the target element's `effects` stack. Builds an `EffectKind::Mask` carrying the matching shape; the eyedropper tool short-

Composite `layer` onto the full `rw × rh` output canvas applying the supplied `Fit` mode. Mirrors the export filter graph's `scale` + `crop`/`pad` pip

For each animatable transform parameter on the selected layer, return the list of `(local_t, scene_t)` keyframe pairs at which that specific parameter

Create a bind group for a texture + sampler pair.

Create a wgpu texture from RGBA pixel data.

Trim the left half's `canvas_layouts` keyframes at scene-time `cut_t`.

Keep keyframes on one side of a scene-time cut and optionally rebase times.

Read the globally-active language.

Remove a per-parameter breakpoint at `at_t`. Shared layout keyframes (other params also change there) are kept — only this field is flattened.

Human-friendly name shown in the language picker.

HTTP GET → file. Videos are streamed to a temp file; callers validate the result before the cache starts using it.

Downscale a ColorImage to a target maximum dimension while preserving aspect ratio. Used to keep the CPU chromakey/CC fast during playback. Returns th

Core overlay drawing implementation. - `pass`: if `Some`, filter overlays by BehindActors/OnTop classification. If `None`, draw regardless of pass (us
