Yes, 100 are the maximum frames we have configured for our proxy initially. Since gifs are 20-30fps iirc, that gives you about 3-5 seconds.

We will have to up that

Edit: I also didn't think it would just cut off the GIF. I thought it would fail processing and fallback to the original url (with requiring a click if configured in the privacy settings)

Thanks for bringing this back into my awareness. I'll make sure this works properly in my current iteration on our image proxy.
