Laurence Tratt: Automatic Video Editing
Amongst the many consequences of COVID-19 has been the suspension of in-person talks: suddenly, people like me have had to think about how to produce prerecorded videos. In this article I’m going to explain what I’ve come to understand about video recording and the “automatic video editing” technique I’ve used for videos such as Virtual Machine Warmup Blows Hot and Cold. To give you an idea of how
FFmpeg: Step-by-Step Retro Video Filter - Gariany.com
FFmpeg: Step-by-Step Retro Video Filter I miss working with FFmpeg, so when I came across this interesting challenge on Reddit, I could not say no. I am currently looking for a new project as an Audio/Video software engineer or project manager and it was a nice break away from interviews. Are you currently hiring or have any interesting project proposals? Get in touch with me! 🌻 So, the challenge
GitHub - mifi/editly: Slick, declarative command line video editing & API
Editly is a tool and framework for declarative NLE (non-linear video editing) using Node.js and ffmpeg. Editly allows you to easily and programmatically create a video from a set of clips, images, audio and titles, with smooth transitions and music overlaid. Editly has a simple CLI for quickly assembling a video from a set of clips or images, or you can use its more flexible JavaScript API. Inspir
Writing a Screencast Video Editor in Haskell
For the last six months I’ve been working on a screencast video editor called Komposition, and it’s now released and open source. This is an experience report, based on a talk from Lambda World Cádiz 2018, that’ll give an overview of Komposition’s design, implementation, testing, and planned future work. Background It all began with Haskell at Work, the series of screencasts focused on practical H
High quality GIF with FFmpeg
About two years ago, I tried to improve the support of the GIF encoding in FFmpeg to make it at least decent. This notably led to the addition of the transparency mechanism in the GIF encoder. While this is not always optimal depending on your source, it is in the most common cases. Still, this was merely an attempt to prevent shaming the encoder too much. But recently at Stupeflix, we needed a wa
Some more Videogreping with Python - __del__( self )
In this post I give a minimalistic version of Sam Lavigne’s Videogrep and use it to promote world peace. This week Sam Lavigne wrote a very entertaining blog post introducing Videogrep, a Python script that searches through dialog in videos (using the associated subtitles file), selects scenes (for instance all scenes containing a given word), and cuts together a new video. The script on Github im
The Technology behind Hyperlapse from Instagram
Welcome to the Instagram Engineering Blog, where we share insights on building and scaling our service. Yesterday we released Hyperlapse from Instagram—a new app that lets you capture and share moving time lapse videos. Time lapse photography is a technique in which frames are played back at a much faster rate than that at which they’re captured. This allows you to experience a sunset in 15 second
Videogrep: Automatic Supercuts with Python – Sam Lavigne
Videogrep is a python script that searches through dialog in videos and then cuts together a new video based on what it finds. Basically, it’s a command-line “supercut” generator. The code is here on github. The script searches through a video’s associated subtitle file (which needs to be in the same folder as the video, in standard .srt format), identifies timestamps for the dialog, and then uses
