In my ever-growing collection of smart FFmpeg tricks, here is a way of converting from one container format to another. Here I will convert from a QuickTime (.mov) file to a standard MPEG-4 (.mp4), but the recipe should work between other formats too. If you came here to just see the solution, here you go: … Continue reading Convert between video containers with FFmpeg
I take a lot of timelapse shots with a GoPro camera. Usually, I do this with the camera’s photo setting instead of the video setting. That is because I find it easier to delete unwanted pictures from the series that way. It also simplifies selecting individual photos when I want that. But then I need … Continue reading Create timelapse video from images with FFmpeg
FFmpeg is a fantastic resource for doing all sorts of video manipulations from the terminal. However, it has a lot of features, and it is not always easy to understand what they all mean. I was interested in understanding more about how the tblend function works. This is a function that blends successive frames in … Continue reading Visual effect of the different tblend functions in FFmpeg
Continuing my explorations of FFmpeg for video visualization, today I came across this very nice blog post on creating “pixel array” images of videos. Here the idea is to reduce every single frame into only one pixel, and to plot this next to each other on a line. Of course, I wanted to try this … Continue reading Pixel array images of long videos in FFmpeg
I am continuing my explorations of the great terminal-based video tool FFmpeg. Now I wanted to see if I could “flatten” a 360-degree video recorded with a Ricoh Theta camera. These cameras contain two fisheye lenses, capturing two 180-degree videos next to each other. This results in video files like shown in the screenshot below. … Continue reading “Flattening” Ricoh Theta 360-degree videos using FFmpeg
