Import of animated GIF as image

[tom95521]

In my alpha channel video test slideshow I noticed the GIF cube (32 MB) created from 1,000 transparent PNGs (45 MB) only decompressed the first 85 frames when imported as an image. I tried adjusting the animated image settings to increase to 1,000 frames but was not successful. If possible read complete frame count and decompress animated GIF into memory. When animated GIF is imported as video it causes slow playback with stutter.

Maybe 64 bit PTE can allocate a larger buffer and decode more of animation in memory than 32 bit PTE.

Thanks,
Tom

Tom,

In future update 10.0.5 we'll increase this limit by 2x times. You can try a new test version now:

In theory, PTE can load all this GIF at once, but it will consume about 1 GB of memory. Because PTE was not optimized to load large Animated GIFs. These images are being converted to 32-bit pixel format (RGBA) and all frames are loaded at once for fast playback.

Ok. I understand that PTE is not optimized for animated GIFs like web browsers. The uncompressed file size is very big.

Thanks,
Tom
