How to convert a GIF file to a AVI file?

I want to convert a GIF file to a video file (AVI or mp4). How can I do that using MATLAB?

Thanks for your response. However, I have some confusions to share. The answer of that question recommends to use im2frame function with loop. Where should I include that loop in the code of the question? I have already tried with the code of the question for my gif file. It gives a video file with complete black screen. Could you please provide me with the complete code. I can't add my gif file here due to its file size.

An example of a loop is given in the documentation for the im2frame function.

Sorry sir, I have gone through the example loop but it is not convincing for my case. The number of images was already mentioned as Eight in the example. However, how can I know the number of images of my gif animation. Also, are you recommending to use im2frame to convert the images of the gif animation to movie frames and then calling all frames to write a video? Sorry for my ignorance.

I've written a function that converts GIF --> AVI based on Walter's 2018 answer.

Download gif2avi()

gif2avi(file) will convert the gif file to avi and will save it to your current directory. See the documentation for that function for additional inputs.

Let me know if you have an problems.

@Anjan Goswami , please update to the latest version (1.0.2). I just fixed a small error that happens when the destination input includes the file extension.

Thank you, sir.

but usually the size of my converted avi files (from gif ) are much bigger than that of the original gif file, like 400MB compared to 2MB, is this normal ? I use the 2.0.0 version
