Updated . FFmpeg.party is an informal resource for FFmpeg generators, tips, tricks, and guides. It’s a side project for me. About »


All I’ve got right now is the time calculator:

Video command generator: x264 & x265
A generator for video conversion to the x264 and x265 codecs.
Duration calculator
A quick calculator that helps you calculate an output duration parameter.
Stable Diffusion WEBM tool
A tool for generating ffmpeg commands that turn a sequence of images into a WEBM video file.


x264 (AVC) encoder parameters
Settings for the x264 encoder that I've found to work very well.
x265 (HEVC) encoder parameters

You can find answers to almost everything you could want to do there.

Updates and Plans

Updated 23 April 2023: improved scripts for all tools, got a start on the basic command generator for x264/x265, and changed the site’s look to dark.

Stuff I want to add next:

  1. A guide to dealing with interlaced NTSC 480p sources, such as digitized VHS tapes or captured DV tapes.
  2. A generator for video filters, probably starting with bwdif, crop, and stuff like that.
  3. Once I have enough content I’ll design and organize the navigation.
