…ones When a clip is split and one half deleted, the editor timeline kept a dead zone for the removed range instead of compacting it. Playback then started from the wrong source position and the clip blocks rendered with a leading gap. Rework the timeline mapping so removed ranges no longer occupy space: - add getKeptTimelineSpans() to compute each kept clip's compacted timeline bounds from its source coordinates - rewrite mapTimelineTimeToSourceTime / mapSourceTimeToTimelineTime to convert through those kept spans (ripple) instead of raw source time - make getTimelineDurationMs sum clip display durations - update clip split / span-change commands to convert timeline offsets back into source coordinates - render clip blocks at their ripple-corrected timeline positions

- Around line 128-133: Update handleClipDelete to compute the deleted clip’s
timeline start and end before filtering zoomRegions, annotationRegions,
speedRegions, and audioRegions, then compare those regions against the computed
timeline bounds rather than deletedClip.startMs/endMs source coordinates. Leave
removedSegments unchanged because it already uses timeline coordinates.
- Around line 85-100: Update handleClipSplit so left.endMs uses the
display-coordinate endpoint target.startMs + splitOffset, while retaining the
safe speed multiplier only for newSourceStart mapping. Keep the right clip
endpoint based on the remaining display duration, and ensure
handleClipSpanChange does not scale newTimelineDuration by speed; preserve the
shared mapping boundary.
In `@src/components/video-editor/types.ts`:
- Line 336: Update the span-match condition in mapTimelineTimeToSourceTime to
use a half-open interval, excluding span.timelineEndMs while retaining the
inclusive start. Preserve the existing final-span clamp and !nextSpan fallback
so the timeline end still maps to lastSpan.sourceEndMs, and add coverage for
boundary mapping alongside findClipAtTimelineTime.

Use timeline bounds when deleting a clip.
zoomRegions, annotationRegions, speedRegions, and audioRegions use timeline coordinates. handleClipDelete compares them with deletedClip.startMs and deletedClip.endMs, which are source coordinates. This can retain regions inside the deleted clip or remove unrelated regions when clips are trimmed or sped. Compute the deleted clip’s timeline start and end before filtering. removedSegments already uses timeline coordinates and should remain unchanged.

- mapTimelineTimeToSourceTime: use half-open span interval so a clip boundary maps to the next kept span, consistent with findClipAtTimelineTime - handleClipSplit: store left.endMs as display end (startMs + splitOffset) and use a safe speed for the source split point - handleClipDelete: filter zoom/annotation/speed/audio regions using the deleted clip's timeline bounds instead of its source coordinates

Problem
When a clip is split and one half is deleted, the editor timeline keeps a "dead zone" for the removed range instead of compacting it. As a result:
Root cause
clipRegionsstore SOURCE coordinates, but the timeline mapping functions(
mapTimelineTimeToSourceTime,mapSourceTimeToTimelineTime,getTimelineDurationMs) treated inter-clip source gaps as fixed "dead zones"in the timeline instead of rippling the remaining clips together.
Changes
getKeptTimelineSpans()to compute each kept clip's compacted timelinebounds from its source coordinates.
mapTimelineTimeToSourceTime/mapSourceTimeToTimelineTimetoconvert through those kept spans (ripple) instead of raw source time.
getTimelineDurationMssum clip display durations.handleClipSplit/handleClipSpanChangeto convert timeline offsetsback into source coordinates.
