![]() With smaller GIFs, the lower framerate is less noticeable, and so we can skip some frames and make smaller GIFs. ![]() I recommend this option because video formats usually have a higher framerate due to the larger resolution. The input FPS can be found with ffprobe, and the total number of input frames can be found with mediainfo as explained at: The perceived output FPS is adjusted to match the input however, so you won't notice a speedup, only greater granularity. The original video height can be found for example with ffprobe: and is 1024 x 1024 in our case.įor example, the original video was 30 FPS, so -r 15 means that ffmpeg will pick one frame in every 2 ( = 30 / 15). If you remove this option, the output GIF has the same height as the input video. This is a common use case for images for the web, which tend to have much smaller resolution than video. vf scale=512:-1: make the output 512 pixels in height, and adjust width to maintain the aspect ratio. No, GIFs are not the best way to pirate distribute videos online. ss 00:00:03 -to 00:00:06: start and end time to cut the video from. We could also play with documented palettegen parameters like palettegen=max_colors=16 to achieve different size quality trade-off points. generation time was 7x slower, presumably because ffmpeg is first scanning through the entire video to determine an optimal palette.TODO: why does simply choosing a palette increase the image size? Is it because now more colors so we need more bits per color? How to observe each palette? the dotting pattern is much less visible now.Image info: 979K, 45 frames, 512x512 apparent size, coalesced, conversion time on a Lenovo P51: 3.5s. vf "scale=512:-1,split palettegen paletteuse" \ We can try to improve the image quality with methods described at:Į.g. The output has a visible dotting pattern, which is not as visible in "ffmpeg + convert" method below. Test data generation procedure described on this post. 500MB however failed because ffmpeg failed to load its shared libraries. The above conversion also worked after a ulimit -Sv 1000000 (DRAM usage limited to 1GB), so it does "not consume huge amounts of memory" like previous attempts I did with Imagemagick which almost killed my machine. ![]() Image info: 426kB, 45 frames, 512x512 apparent size, coalesced, conversion time on a Lenovo P51: 0.5s. You likely want to use something like: sudo apt install ffmpeg Ps: sry for that bad English i hope it isn't too bad.Ffmpeg 3.4.4 can do it directly on Ubuntu 18.04 I Hope this will help someone to not getting crazy. there is a lot of Bulls * but there is also a lot of stuff what you can use very nice in this way! Have a look at the "free animation gif" sites. Well and as i said, if your looking like a crazy for a animation like smoke, fire, or what so ever. file/d/0B-ELG2wt0x1ZNnlJdEo4Q0xtUmM/edit The nice thing is now you can work whit it like every other image on construct, stretching and do what ever you like to do. Well now you just make a new Sprite in your Project, import all the Pictures as Animation Frames, make the Settings, like for the fire i used "loop = yes" and "speed = 10", just play around how you will need and how it looks god to you. In this Folder now shud be a couple of Pictures. Once you have downloaded the zip, you have to decompress it somewhere on you computer. This you can do very simple on this Site: uk./gif-extract First to do is you have to "Decompose" the gif.
