[Sokudo] Goblin Slayer II - 01 [1080p][AV1][multisub] (weekly)

Same one from [Breeze] https://nyaa.si/view/1726106
How come this one is not labelled as a remake?

What does “Same one” mean? I’d like to kindly respond to your comment but I’m not what sure you’re saying. I edited the description for you.

Why is this release less than half the size of the other one when they have the same description?

Bitrate (not description) determines file size? I'm not sure I entirely understand your question but I'm happy to answer questions when possible.

Considering that Nyaa culture and its satellite communities/offshoots are a bit unintuitive for newer users (and sometimes even older ones), it might be worth it to update the copy-paste portions of your upload description template to include your explanation of the differences between the releases, and (for more careful batch/BD releases) perhaps even including the encoder/toolchain settings used so that more experienced/knowledgeable people can see at a glance what the differences are.

My assumption when I first noticed your double-release methodology was that the smaller files were more aggressively denoised/degrained to save on bitrate and file size, whereas the larger ones preserved original grain/detail as much as possible.

Of course, seeing that you mention in the Breeze post that you pass CQ=10 to aomenc for that release, maybe it's something as simple as different CRF/CQ values, in which case, voila.
