So this artist/circle makes these animated things and posts them on their website, locked behind a password that you get when you buy their doujins. On the public pages of the blog, they upload very low resolution previews. On the locked pages, they have versions of the full videos in standard resolution, as well as MEGA links for the full res versions. A while ago, I figured out it's usually pretty easy to fuzz the URL to get the locked preview just based on what the URL for the low res version is. So, let's say you want Aqua. Go ahead and copy the link to the video for the low resolution, you'll find its path is
/blog/wp-content/uploads/2021/01/kaitsushin-Aqua4.mp4

The version you can access on the locked page always has "SHD" appended to its filename.

404, so that's not it.

The preview versions sometimes end up with a higher number than other revisions because they make and upload them to the site after the full ones are done, so try removing or lowering the number.

another 404.

The preview versions also sometimes get added a month or two later than the full one.

And there it is.

This is all pretty pointless though, since the doujin and its password will eventually get uploaded on sadpanda
