How to Export Low-Res Sprite Animation GIFs as HD Versions?

[itsmedominie]

I have a whole set of sprite animation GIFs that I'm trying to convert into HD. The process itself works fine, but when I try to export them as animated GIFs using Export for Web (Legacy), I encounter an "unknown error" that forces me to lower the quality. With shorter ones this only means converting them to 720p instead of 1080, however with the longer ones even this will not suffice and I'm forced to put them in 480 or lower, which is far from ideal.

I just want to check if anyone has a solution to this "unknown error" issue that means I'll be able to export them all in at least 720p. If not, I may have to settle for 480.

How to Export Low-Res Sprite Animation GIFs as HD Versions?  Actually that is not posible.  If you start with a  Low-Res Sprite Animation GIFs you have low resolution low quality frame layers. Gif format only supports up to 256 colors.  

If you resample the document to up its resolution you will loose more image quality.  You will have more pixels but the image will be poorer.  Resampling up in size does not work as well as resampling  down in size.     When you resample down in size you lose image quality because you discard details you have for the image but the smaller images should still look quite good in its smaler size.  When you resample up in size you have to creat details you do not have for the image.   Up sample image lose quality because of this. Yes the image is bigger but lack good detail the image  look softer or out of focus at its new larger size.  You have the required number of pixels for HD but you do not have high quality pixels for the image. They lack good detail.

If you want a good 1080p Animation you need you start with high resolution layers with full color and you need export with better quality then GIF like a MP4 Video you can even add audio,

This is correct for most footage, but in the case of pixel art I've found it's possible to upscale it to work at a higher resolution using the 'Nearest Neighbour (hard edges)' resample setting. The pixels are supposed to be visible anyway, so simply making them larger and still crisp works fine.

My issue is not with that but with exporting the footage, which results in an unknown error if the GIF has too many frames. A friend of mine has managed to convert the same sprite animation GIFs to 1080 in Gimp, and as such I thought the same must be possible in Photoshop.

Its seems the Photoshop has a bug or frame limit that gimp does not have. Submit a bug report at Photoshop Family Customer Community  perhaps Adobe will accept it as a bug and fix it. In the mean time have you friend convert your animation with gimp
