![]() To get ImageMagick to work, I first had to modify its disk and memory limits at /etc/ImageMagick-6/policy.xml as explained at: GIF from video: How to create an animated GIF from MP4 video via command line?.Set the width, scale height proportionally, usually to reduce size and save space. It still takes 4 seconds to play, so the delay is altered to make things match. With it, identify out.gif says that the GIF contains only 64 frames. Pick one every 4 images so reduce size ( 4 = 60 / 15). ![]() The 256 input frames take about 4 seconds to finish. framerate 60: assume 60 FPS on input images, and output the same FPS.įfmpeg cannot know otherwise, since there is no FPS data is in images as there is is in video formats. pattern_type glob: convenient way to select images The important ffmpeg options I want to highlight are: The test data was generated with: and contains 256 1024x1024 PNG images.Īnd here is another test data that you can generate directly in your browser right now! You can get my test data with: wget -O opengl-rotating-triangle.zip The simplest conversion command is: ffmpeg \ Sorting numerically is quite tricky on Mac OS X though, I guess you'll need to build a custom script.Īs of Ubuntu 18.10, ffpmeg 4.0.2-2, ImageMagick 6.9.10-8, I have found that ffmpeg is much faster than ImageMagick, and uses much less memory. On ubuntu you can use ls -v instead, something like: convert -resize 768x576 -delay 20 -loop 0 `ls -v` myimage.gif $ ls|catĪs the shots were taken very quickly (10/s) they all have the same modification time and you can't trick using ls -t for example. *.jpg sucks a bit when dealing with numeric values, you may generate a gif with unsorted pics. Or convert -resize 768x576 -delay 20 -loop 0 *.jpg myimage.gif In my case, I have 4608x3456 images and the generated gif was more than 300M for 32 images convert -resize 20% -delay 20 -loop 0 *.jpg myimage.gif Java is a registered trademark of Oracle and/or its affiliates.To complete answer: To avoid generating a very large file, you can use -resize option: For details, see the Google Developers Site Policies. ![]() This manual page was written by Urvang Joshi for theĭebian project (and may be used by others).Įxcept as otherwise noted, the content of this page is licensed under the Creative Commons Attribution 4.0 License, and code samples are licensed under the Apache 2.0 License.

When lower values are used, more frames will be converted to key frames. These two options are relevant only for animated images with large number Lossless compression and kmin = 3, kmax = 5 for lossy compression. Default values are kmin = 9, kmax = 17 for Taken into account in both these special cases. Of 1 will result in all frames being key frames. Insert some key frames into the output animation as needed so that thisĪ kmax value of 0 will turn off insertion of key frames. (independently decodable frames) in the output animation. Specify the minimum and maximum distance between consecutive key frames Result in faster processing time at the expense of larger file size and Values are used, the encoder will spend more time inspecting additionalĮncoding possibilities and decide on the quality gain. Off between encoding speed and the compressed file size and quality. m int Specify the compression method to use. Uses lossless compression by default, but can be combined with -q, -m, Picks the dispose method resulting in the smallest output for each frame. min_size Encode image to achieve smallest size. Best quality is achieved by using a value In case of lossyĬompression (specified by the -lossy option), a small factor produces a MaximumĬompression is achieved by using a value of 100. In case of lossless compression (default), a small factorĮnables faster compression speed, but produces a larger file. q float Specify the compression factor for RGB channels between 0 and 100. mixed Mixed compression mode: optimize compression of the image by pickingĮither lossy or lossless compression for each frame heuristically. lossy Encode the image using lossy compression. h, -help Usage information -version Print the version number (as ) and exit. The data will be read from 'stdin' instead of a file. This option must appear last.Īny other options afterward will be ignored. This option is useful if the inputįile starts with an "-" for instance. string Explicitly specify the input file. Using "-" as output name will direct output to 'stdout'. Perform conversion but only report statistics. The basic options are: -o string Specify the name of the output WebP file. Gif2webp converts a GIF image to a WebP image.
