Does this optimise the gifs using gifscle?
- lettier 9y ago
  Hello. Gifcurry does not optimize using Gifsicle. It employs the optimizations afforded by ImageMagick. In most cases the Gifsicle file size reduction is only minimal (even with the "-O3" flag). Still, if desired, I could add this extra step. Thank you for commenting.

    If you decide to implement optimizations beyond imagemagick's ones, you might want to consider other tools than Gifsicle: - lossygif for small size, based on gifsicle, https://kornel.ski/lossygif https://kornel.ski/lossygif - Gifski for high quality, based on pngquant, (https://gif.ski/ https://gif.ski/) Both are made by Kornel Lesiński. Lossygif is actually result of a pull request being ignored by gifsicle maintainer(s) for years – more details in a recent HN thread: https://news.ycombinator.com/item?id=16573627 https://news.ycombinator.com/item?id=16573627.

This is really nice. Removes some of the overhead. I was able to install using yaourt in Arch. Here's my output, first time using it https://i.imgur.com/rRiHZXv.gifv https://i.imgur.com/rRiHZXv.gifv (original video size: mp4 1.1mb, output gif 6.3mb) And here's some feedback: - I'm unable to resize the window at all. - A preview of the text would be really nice. - Loved the menu, thought I would be confusing but I notice it wasn't. - Thought the upload buttons were direct uploads but it's more of a shortcut to the upload pages.

  Hello. Gifcurry controls the window size to maintain an accurate preview of the video (no added bars, wrong aspect ratio, etc.). This becomes important when cropping. If desired, I can add a preview size setting. A preview of the text would be nice. This will be a future feature. The upload buttons are shortcuts. This avoids having to maintain and distribute/reveal API keys. It also avoids having to keep the integration accounts in good standing. The quality setting can reduce the final file size. Still, using your benchmark, I tweaked the optimization and pushed an update to the AUR. At 100% quality: https://imgur.com/a/YRQot https://imgur.com/a/YRQot [0] (2.8 MB). The top end quality (100%) is not as nice but with a 55% reduction in file size, the appearance is still very acceptable. You can also save the final GIF as a video. As a video at 100% quality: https://imgur.com/a/8nRxc https://imgur.com/a/8nRxc [0] (166 kB). Thank you for taking the time to review Gifcurry.
