8mb

8MB video compression PowerShell script for ffmpeg.

Prerequisites

• Windows PowerShell
• ffmpeg
• ffprobe

Usage

Download the Windows binaries for both ffmpeg and ffprobe from the Prerequisites section and extract them into the script directory.

If either binaries are in PATH, they will be searched for there first.

Shell Extension

Run Register.bat to extend the context menu of *.mp4 files with the script.

Right-clicking any *.mp4 file will have a new sub-menu with different size presets.

If the location of 8mb.ps1 changes, running Register.bat again will update the location in the registry accordingly.

Command Line

PS > .\8mb.ps1 -Source      [string]                   # the source file path.
               -Size        [uint64]                   # the destination file size.
               -SizeUnits   [KB|KiB|MB|MiB] (optional) # the destination file size units (MB is default).
               -Scale       [float]         (optional) # the destination resolution scale.
               -FPS         [float]         (optional) # the destination FPS.
               -Destination [string]        (optional) # the destination file path.
               -NoUpdates   [switch]        (optional) # disables the auto-updater on start.
