Then 256 color palette is generated using the created snippet.

-vframes sets the number of video frames to output.ffmpeg -ss 1:25 -i avengers.mp4 -vframes 1 -vf scale=720:-1 snippet.jpg To create the palette one frame needs to be extracted. -t limits the duration of data read from the input file.In this case, extraction will begin from 1 min 24 sec. -ss seeks the specific timestamp in the input file.By the way, only 2 seconds are needed from the input file, so the specific part will be converted to the GIF. Firstly, let’s create the GIF with the default color palette, it will be used for the comparison. Convert video to GIF using a color paletteĪs was mentioned before, the GIF format stores a global palette which can be re-defined with custom colors to get better quality. GIF with the custom palette has higher quality and takes 279 KB. Since the GIF is mostly text sharpness can be improved a little bit. Also, frame rate was reduced to 5 fps, as for this GIF animation smoothness is less important. It’s good that the recording can be trimmed in FFmpeg without having to open an additional video editing software. crop trims pixels, “iw:ih-2:0:0” tells to trim 2 px from the bottom.įile size can be reduced by lowering the frame rate, scaling down the image, and reducing the color palette.įor some reason, QuickTime always gives the recorded video of the screen with a black line at the bottom.smartblur blurs or sharpens the video, “ls” means “luma_strength” - one of the smartblur options.scale sets the width and height, “-1” preserves aspect ratio.fps is a string describing output framerate (default “25”).-i is an input key that follows with the filename you want to convert.That was the simplest command, now let’s add visual filters to customize the output. In Terminal navigate to the folder with the video you want to convert and run the command to create a GIF.
Ffmpeg gif fps install#
Install FFmpeg running the following script in Terminal. Install Homebrew running the following script in Terminal. FFmpeg has good performance and can work with large files. Among online converters, it is one of the best, but it limits FPS depending on the video duration. Ezgif has an upload limit of 2000 files and max file size of 6MB each or 100MB in total.
Ffmpeg gif fps mac#
Not to mention that it’s available only on Mac while FFmpeg is cross-platform and doesn’t have such limitations.

Also, in the free version, it puts watermark and doesn’t make GIFs longer than 10 seconds. Giffox records only selected snippets of the screen but doesn’t allow to upload videos from a local folder. It’s time-consuming and Photoshop is not my primary design tool anyway, so I had to look for the other options. However, long and smooth animations have to be created using workarounds, as Photoshop has a 500 frames limit. I used to create GIFs in Adobe Photoshop. Thus, conversion settings have to be played with to balance image quality and file size. GIFs are restricted to 256 colors palette and lose quality when the complexity of animation increases. Despite many advantages, this file format has a number of limitations. Notice that only the pixels that change from one frame to the next are present.High-quality animation on any platform for freeĬreated in 1987, GIF remains to be a widely used format for saving short and lightweight animations on the web. Here’s the first three frames of the gif above. 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.
