Command-line tool for generating thumbnails of videos using FFmpeg and Topaz Video AI

Thumbnailer

This is a command-line tool to process video files in bulk. It currently produces several files which are 1920p, 29.97 fps, with low quality compression.

1. A proxy for smoother video editing
2. Some previews for quick browsing. These include a look-up table (LUT) and automatic smoothed brightness normalization:
   1. Original video
   2. Original video with Topaz Video AI stabilization (at 100% strength auto-crop with rolling shutter correction)

For me, these files are each ~100× smaller than the original (which on my Sony A6700 is XAVC-I 4K @ 59.94 fps, which is 600 Mbit/s or ~4.5 GB per minute).
