Auto Vid Compiler

Drop in a folder of clips and get one finished highlight reel. The app trims the last few seconds from each clip, prepends your intro, layers background music, and exports a single YouTube-ready video — no editing timeline required.

Auto Vid Compiler Runtime

Point it at a folder. Get back a finished video.

Input Any folder of .mp4 / .mkv clips
Trim 5–30s extracted from each clip end
Output Single compiled .mp4 with intro + music
Engine Bundled FFmpeg — no install needed
Portable

Runs as a standalone .exe — FFmpeg is bundled. No Python or additional installs required on the target machine.

Clip-aware

Processes each video file in the selected folder individually, then stitches everything into one seamless output.

Configurable

Set trim length (5–30 seconds per clip), select your intro file, choose a background music track per session.

Open Source

Full source available on GitHub. Fork it, modify the workflow, or adapt the FFmpeg pipeline for your own use case.

What It Does

A focused automation pipeline — no general-purpose editor, just the one job it was built to do.

Folder-Based Input

Point the app at a folder of clips. It picks up every video file in order and runs the same trim workflow on each one.

Auto-Trim Endings

Extract the last 5–30 seconds from each clip. Works for gaming highlights, event recordings, or any footage where endings are the payoff.

Intro Prepend

Drop your own intro video file next to the executable. The compiler automatically stitches it to the front of the final output.

Background Music

Select an audio track and it gets mixed under the compiled video at a set audio level — original clip audio is preserved on top.

Important Setup Note

The .exe must run alongside its bundled folders.

This is a portable-style distribution — the executable expects to find its companion folders (FFmpeg, intros, music, icons) in the same directory. Do not move the .exe out of the extracted folder or the app won't find its assets.

music/ Place your background audio tracks here.

Tech Stack

  • Python — core process and GUI logic
  • FFmpeg — video trimming, concat, and audio mix
  • PyInstaller — packaged into a standalone Windows .exe
  • Bundled assets — intros, music, icons included in release

Best Fit For

  • Gaming clip highlight reels (the original use case)
  • Content creators who batch-process short recordings
  • Anyone who needs the same repeatable compile workflow run often

Quick Start

Download, extract, drop in your files, and run.

01

Download the release

Grab the .exe from the GitHub Releases page. Extract everything — keep all bundled folders together in one directory.

02

Add your intros and music

Drop your intro video into the intros/ folder and your background audio into music/.

03

Point it at your clips folder

Run the .exe and select the folder containing your source clips. Set the trim length per clip (5–30 seconds).

04

Export and upload

Hit compile. The app processes each clip in sequence and delivers one finished .mp4 ready for YouTube.
