Video Merge GPU

Merges multiple videos from a folder (sorted by filename) into one clip with a random xfade transition (0.5s) between each pair; freeze-pads so total duration equals the sum of sources.

What it does

Video Merge GPU is an agent skill from godot-fun/gai. Merges multiple videos from a folder (sorted by filename) into one clip with a random xfade transition (0.5s) between each pair; freeze-pads so total duration equals the sum of sources. Encodes with GPU HEVC only (NVENC / AMF / QSV — no CPU libx265 fallback). Exports 3840×2160 60fps H.265 Main10 40Mbps + AAC 320kbps. Use when the user wants video-merge-gpu, GPU video merge, NVENC merge, hevcnvenc concat, GPU concat, GPU video merge, or batch stitch clips with xfade on GPU.

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `reference.md`).

It sits in Media & Creative. It works with FFmpeg and Python. The repository describes itself as: A lightweight AI agent and skill workflow framework built with Godot. The licence is MIT.

When your agent uses it

The user wants video-merge-gpu
GPU video merge
Hevcnvenc concat
Batch stitch clips with xfade on GPU

Example prompts

“Use the video-merge-gpu skill to merge multiple videos from a folder (sorted by filename) into one clip with a random xfade transition (0.5s)…”
“/video-merge-gpu”

Requirements

Python 3

Workflow steps

8 steps, taken from the first numbered list in SKILL.md.

Use the bundled script — do not hand-write ffmpeg xfade chains.
Transition duration is fixed at 0.5s — no duration override flag.
Every clip except the first must be longer than 0.5s (incoming side of xfade).
Single file in the folder → re-encode to the output spec with no transition.
Many clips (4K10) auto-chunk (max 8 inputs per filtergraph) to avoid OOM; transitions stay correct across chunk boundaries.
No CPU fallback. Missing GPU HEVC Main10 → report the probe failure; suggest video-merge only if the user accepts CPU.
Missing Python/FFmpeg → populate .dependency/ per skill-dependency-manager, retry.
FFmpeg filter / encoder details: reference.md

What it can do on your machine

Read from SKILL.md and the folder at commit 6394686. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- python
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Video Merge GPU loads about 1k tokens when it runs. Until then it costs about 124 tokens; SKILL.md has 375 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~124
When it runs · the whole SKILL.md, loaded when a task matches: ~1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Video Merge GPU

Same merge as video-merge: concatenate every video in a folder (filename sort) into one high-quality MP4, random FFmpeg xfade (0.5s) + matching acrossfade, freeze-pad so output length equals the sum of source durations.

GPU encode only. Probe hevc_nvenc → hevc_amf → hevc_qsv (HEVC Main10). If none work, fail — do not fall back to libx265. Use video-merge when CPU encode is wanted.

xfade / scale / pad still run on CPU; only the H.265 encode is hardware.

Rules

When this skill applies, read and follow skill-dependency-manager — run scripts as documented, install missing tools into .dependency/.

Run merge.py through .dependency/python/python.exe. Never use host python / ffmpeg.
Never overwrite sources. Outputs go under video-merge-gpu/.
Use the bundled script — do not hand-write equivalent FFmpeg commands.
Folder input only — pass --folder with a directory of clips (top-level files; no recurse).

Quick Start

bash

.dependency/python/python .ai/video-merge-gpu/merge.py --folder path/to/clips

Example:

assets/shots/
  01.mp4
  02.mp4
  03.mp4
→ assets/shots/video-merge-gpu/shots.mp4

Output Spec (fixed)

Setting	Value
Resolution	3840×2160 (scale + letterbox pad)
Frame rate	60 fps
Video	H.265 Main10 (GPU: `hevc_nvenc` / `hevc_amf` / `hevc_qsv`, `p010le`) @ 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.

bash

.dependency/python/python .ai/video-merge-gpu/merge.py --folder clips
.dependency/python/python .ai/video-merge-gpu/merge.py --folder clips -o out/final.mp4

Never overwrite source files. Input must be a folder (--folder), not a single video file. 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.

Agent Notes

Use the bundled script — do not hand-write ffmpeg xfade chains.
Transition duration is fixed at 0.5s — no duration override flag.
Every clip except the first must be longer than 0.5s (incoming side of xfade).
Single file in the folder → re-encode to the output spec with no transition.
Many clips (4K10) auto-chunk (max 8 inputs per filtergraph) to avoid OOM; transitions stay correct across chunk boundaries.

Video Merge GPU is an agent skill from godot-fun/gai.5s) between each pair; freeze-pads so total duration equals the sum of sources.

When should I use Video Merge GPU?

Video Merge GPU fits situations like: the user wants video-merge-gpu; GPU video merge; hevcnvenc concat; batch stitch clips with xfade on GPU.

How do I install Video Merge GPU in Claude Code?

Run `npx skills add godot-fun/gai --skill video-merge-gpu -a claude-code`. Or copy the skill folder (.agents/skills/video-merge-gpu in godot-fun/gai) into .claude/skills/video-merge-gpu in your project. Claude Code loads it when a task matches its description.

Can I use Video Merge GPU in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add godot-fun/gai --skill video-merge-gpu -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/video-merge-gpu, .gemini/skills/video-merge-gpu, .github/skills/video-merge-gpu and .opencode/skills/video-merge-gpu in your project.

What does Video Merge GPU need to run?

Going by SKILL.md and its folder, Video Merge GPU needs the command-line tools its instructions call (python). Our summary lists: Python 3.

Does Video Merge GPU access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Video Merge GPU safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Video Merge GPU use?

Video Merge GPU is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Video Merge GPU use?

About 1k tokens (SKILL.md is roughly 4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
