First time poster here! Anytime I try do download a video, it gives me a weird version of it where its only a couple of Kbs big, and if I try going to the "original image" link at the bottom of the post, it brings me back to the post instead of a new tab with just the video to download, ive tried converters for the file but nothing seems to work, this has been happening for weeks, months even. dont know if its a region issue or what so help would be greatly appreciated.

I've noticed the weird behavior with the "Original Image" option myself, It just reloads the page for me these days instead of going to the image by itself. I've been using the "Fit Image to Window" option instead which is close enough for me.

I don't have a fix or explanation for the video downloading issue you've got, but I have some detours you can use to get the files another way:

1 - Check Danbooru and see if they have the image/video, alot of our images are sourced from there.
Danbooru has a download link on the image pages that you can click instead of clicking on the image/video.
You can also check other image sites that might have it.

2 - Try the source link in the "Statistics" section of the image page, just under the tags.
You might be able to download the image or video straight from the source.
(Alot of people use twitter/x as the source, so you'll likely need an account for that)
