Preview Execution monitoring

We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

About

Video Merge

Concatenate every video in a folder (filename sort) into one high-quality MP4. Between each pair, pick a random FFmpeg xfade transition (0.5s). Audio uses matching acrossfade.

Duration is preserved: each cut freeze-pads the outgoing clip by 0.5s (last frame + silence) before the overlap, so output length equals the sum of source clip durations (not shortened by transitions).

Rules

When this skill applies, read and follow [skill-dependency-manager](../../rules/skill-dependency-manager.md) — run scripts as documented, install missing tools into .dependency/.

Quick Start

.dependency/python/python .cursor/skills/video-merge/scripts/merge.py path/to/clips

Example:

assets/shots/
  01.mp4
  02.mp4
  03.mp4
→ assets/shots/merged/shots.mp4

Output Spec (fixed)

| Setting | Value | |---------|-------| | Resolution | 3840×2160 (scale + letterbox pad) | | Frame rate | 60 fps | | Video | H.265 Main10 (libx265, yuv420p10le) @ 40 Mbps | | Audio | AAC 320 kbps, 48 kHz stereo | | Transition | 0.5 s, random from the pool below (freeze-pad; duration preserved) | | Container | .mp4 (hvc1 tag) |

Transition Pool (random per cut)

fade · dissolve · wipeleft · wiperight · wipeup · wipedown · slideleft · slideright · circlecrop · pixelize · distance · radial · smoothleft · smoothright · circleopen · circleclose · diagtl · diagtr · hblur · zoomin

Each cut independently samples one transition. Printed in the run log.

Common Flags

-o / --output · --overwrite · --dry-run · --seed

.dependency/python/python .cursor/skills/video-merge/scripts/merge.py clips --seed 42
.dependency/python/python .cursor/skills/video-merge/scripts/merge.py clips -o out/final.mp4 --overwrite

Never overwrite source files. Default output: /merged/.mp4. Only top-level videos in the folder (no recurse). Supported: .mp4, .mkv, .mov, .avi, .webm, .wmv, .flv, .m4v, .mpeg, .mpg, .ts, .mts, .m2ts, .3gp, .ogv, .ogg.

Agent Notes

  1. Use the bundled script — do not hand-write ffmpeg xfade chains.
  2. Transition duration is fixed at 0.5s — no duration override flag.
  3. Every clip except the first must be longer than 0.5s (incoming side of xfade).
  4. Single file in the folder → re-encode to the output spec with no transition.
  5. Many clips (4K10) auto-chunk (max 4 inputs per filtergraph) to avoid OOM; transitions stay correct across chunk boundaries.
  6. Missing Python/FFmpeg → populate .dependency/ per skill-dependency-manager, retry.
  7. FFmpeg filter details: [reference.md](reference.md)
