![]() ![]() At the same time, however, I was wondering what neat utility might exist to allow me to create a GIF of that video. I not only created a logo for my website project, but, with the aid of SnapZ Pro, I video captured the animation and saved it as a QuickTime movie. Now only is that both cool and mind-boggling, but if you grab the handles of the object box which contains the circular text you just created, you can watch the text spin around and settle wherever you stop dragging the handle. This example will skip the first 30 seconds ( -ss 30) of the input and create a 3 second output ( -t 3).įfmpeg -ss 30 -t 3 -i input.mp4 -vf "fps=10,scale=320:-1:flags=lanczos,split palettegen paletteuse" -loop 0 output.gif #GIF BREWERY 3 WINDOWS DOWNLOAD#īefore you start it is always recommended to use a recent version: download or compile.It was only last night-or should I say about 2 AM, since I'm on steroids that give me insomnia, along with a boost of energy that keeps me up for 2-3 days at a shot, before I crash-I upgraded to version 3 of The Print Shop, and I played around with their Circular Text tool that allows you to spin text into a circle or a spiral.scale filter will resize the output to 320 pixels wide and automatically determine the height while preserving the aspect ratio.Ī rate of 10 frames per second is used in the example.palettegen and paletteuse filters will generate and use a custom palette generated from your input.These filters have many options, so refer to the links for a list of all available options and values. split filter will allow everything to be done in one command and avoids having to create a temporary PNG file of the palette.Īlso see the Advanced options section below.Control looping with -loop output option but the values are confusing.A value of 0 is infinite looping, -1 is no looping, and 1 will loop once meaning it will play twice. So a value of 10 will cause the GIF to play 11 times. The palettegen and paletteuse filters have many additional options. You can force the filters to focus the palette on the general picture ( full which is the default), only the moving parts ( diff), or each individual frame ( single). For example, to generate a palette for each individual frame use palettegen=stats_mode=single & paletteuse=new=1.ĭither (paletteuse). There are three main types: deterministic ( bayer), error diffusion (all the others including the default sierra2_4a), and none. Your GIF may look better using a particular dithering algorithm, or no dithering at all. If you want to try bayer be sure to test the bayer_scale option too. vf "fps=10,scale=320:-1:flags=lanczos" a filtergraph using the fps and scale filters.įfmpeg -i input.mp4 -vf "fps=10,scale=320:-1:flags=lanczos" -c:v pam -f image2pipe - | convert -delay 10 -loop 0 -layers optimize output.gif See High quality GIF with FFmpeg for explanations, example images, and more detailed info for advanced usage.Īlso see the palettegen and paletteuse documentation for all available options and values.Īnother command-line method is to pipe from ffmpeg to convert (or magick) from ImageMagick. fps sets frame rate to 10, and scale sets the size to 320 pixels wide and height is automatically determined and uses a value that preserves the aspect ratio. The lanczos scaling algorithm is used in this example. The example outputs the PAM (Portable AnyMap) image format which is a simple, lossless RGB format that supports transparency (alpha) and is supported by convert. f image2pipe chooses the image2pipe muxer because when outputting to a pipe ffmpeg needs to be told which muxer to use. delay See Setting frame rate section below. layers optimize Will enable the general purpose GIF optimizer. See ImageMagick Animation Optimization for more details. It is not guaranteed that it will produce a smaller output, so it is worth trying without -layers optimize and comparing results. Set frame rate with a combination of the fps filter in ffmpeg and -delay in convert. This can get complicated because convert just gets a raw stream of images so no fps is preserved. Secondly, the -delay value in convert is in ticks (there are 100 ticks per second), not in frames per second. ![]() For example, with fps=12.5 = 100/12.5 = 8 = -delay 8.Ĭonvert rounds the -delay value to a whole number, so 8.4 results in 8 and 8.5 results in 9. This effectively means that only some frame rates are supported when setting a uniform delay over all frames (a specific delay can be set per frame but that is beyond this answer). Delay appears to be ignored if used as an output option, so it has to be used before - as shown in the example. ![]()
