These controls will appear at the bottom of the VLC window, above the normal VLC controls. In the drop-down menu we are going to check the box that appears next to ' Advanced controls'. To do this, in the main menu located at the top of VLC, we click on ' See'. We will start by enabling these controls. VLC has built-in recording capabilities that we can use to create our clip from an existing long video. We will use the most direct in this example. In VLC we will find a couple of ways to cut a video. For this reason, to start creating the GIF, we will have to reduce our video file to the size we want for the GIF. If you don't have them installed yet, you just have to open a terminal (Ctrl + Alt + T) and type: sudo apt install vlc gimp ffmpeg Create a clip with VLCĪnimated gifs are usually not long-lived. We will be able to install them through our package manager. All are easy to install on our Ubuntu system.
If you want to peak at the internals of a gif, you can use gifsicle -e input.gif to explode the frames. We get a little bit of colour banding, but I think that’s acceptable. This means that the areas without motion will remain the transparent from one frame to the next.įor our longer gifs, this method cut our file size down by about 40%. In our case, since the images were synthetic (i.e., not photographic), dithering using the Bayer algorithm worked quite nicely.ĭiff_mode=rectangle restricts area to only the regions where there is motion. Have a look a the different options for dithering as they’ll each have a different effect depending on your content. I found that without this, some static pixels would still change colours ever so slightly between frames.ĭithering with a bayer_scale=5. This will generate a smaller palette because FFMPEG will only look at the pixels that do not change from one frame to the next. Using stats_mode=diff when generating the palette. I won’t go into each option we’re passing to FFMPEG here, but there are a couple things that differ from the original blog post.
You can find a more detailed explanation of this in FFMPEG’s Filtergraph Docs Explanation of Options
