Delay in rendered GIF

[iamnottheway]

I'm using gifjs to convert a canvas animation into a GIF and so far it has worked alright. But the problem I'm facing is that the resulting output has some sort of delay in between each frame, so the animation is pretty slow. I've tried setting the delay value in addFrame to the lowest value possible but for some reason, it just doesn't seem to work.

Here's the example, as you can see it's very slow.

Is there a way to remove this delay? Am I doing something wrong? I'd appreciate any help, thanks!

GIF viewers have a minimum delay below which it will default to a longer delay.
Try increasing the delay to 20ms.

@1j01 I tried it, doesn't work. For some reason, it makes it slower. I think it's the library?

I don't know. If you play around with the delay, can you find a point at which decreasing the delay stops making it faster?
Also, if you only need a handful of gifs, https://ezgif.com/speed is good for this.

@HarowitzBlack May I ask you what short of canvas animation is it? A Lottie Animation?

I had a similar issue while doing Lottie to GIF. Solved it by calculating the delay ms value based on the animation frame rate. Let me know.

@ahmedmaazin Hi yes, it was a Lottie animation. I was trying to convert Lottie to GIF. Would you be kind enough to tell me how you did it? Thank you!

@HarowitzBlack Sure let me try to explain below...:

// Calculate the ms delay by the Lottie instance frame rate.
this.delay = (1 / this.lottie.frameRate) * 1000;

// Set the delay here.
gif.addFrame(img, {delay: this.delay});

Let me know how it goes. Also do share some sample snippet of your implementation.

Thank you so much, It's working!! I'm using fabricjs to load the little into the fabricjs canvas and passing each frame of it into gif.js to render it. Here's a snippet of it

`
const fabricGIFCanvas = gifRender.fabricCanvas;
const animItem = gifRender.animatedBodyMovinContent;
const delay = (1 / animItem.frameRate) * 1000;

    fabricGIFCanvas.clear();
    fabricGIFCanvas.setHeight(450);
    fabricGIFCanvas.setWidth(600);

    animItem.addEventListener('enterFrame', e => {
      fabricGIFCanvas.requestRenderAll();
      this.state.gifObject.addFrame(fabricGIFCanvas.lowerCanvasEl, {
        delay: delay,
        copy: true,
      });
    });

    animItem.addEventListener('complete', e => {
      this.state.gifObject.render();
    });

    animItem.addEventListener('DOMLoaded', () => {
      window.tempEl = animItem;
      animItem.goToAndStop(1, true);
      const fabricImage = new fabric.fabric.AEAnimation(gifCanvas, {
        objectCaching: true,
        scaleX: 0.8,
        scaleY: 0.8,
      });
      fabricGIFCanvas.add(fabricImage);
      fabricGIFCanvas.centerObject(fabricImage);

      fabricGIFCanvas.requestRenderAll();
      animItem.play();
      this.setState({
        animItem: animItem,
      });
    });

Nice. Glad to hear that it works. 👍
