I just looked at the wikipedia for interlaced videos, and while I have no firm evidence for it…

The old video was simply using what could be described as an “inferior method of scanning” when comparing it to 720p or 1080p. I don’t know how that could have happened, but I would guess you just happen to have a PC that supports using interlacing while most of the modern PCs do not.

I could try to explain it in detail but I think it’d just bore you :V

I'm gonna be honest... I'm tired of pieces getting taken down for stuff like interlacing and frame blending, AKA things I don't even notice when I watch them. I'm really tired of it.

Oh don't worry, it's hard to bore me :3
I just want to understand.
I have a high end pc for rendering with a 4090, and I use Blender and DaVinci.
I don't know if that helps, I just want to make sure in the future this doesn't happen anymore.

Also keep in mind that the original output format is much higher quality, but e621 doesn't allow that.
I have to convert it in webm.

You might be able to use a site like MEGA or Dropbox for full resolution uploads. Apart from that I'm not sure. I've seen other artists post here to get their stuff seen, then post a link to full res on MEGA.

That's a good suggestion, but it can only work if they don't delete this post in the first place... :c

I just want to know where you got that model

It's the standard Koraidon model that you find anywhere online, I edited it and rigged to fit my needs ^^

So here’s a TIL,

Apparently the p in 720/1080p can sometimes end in i as well. P stands for Progressive while I stands for Interlaced.

Interlaced rendering involves having two halves of the same image in order to have it a higher quality, but this rendering was only useful in previous years as it was primarily used in analog technology, which was not used since the 80s.

Most apps/devices could still “deinterlace” these videos without compromising it’s quality, but even if it could the quality may still be pretty bad. The method of having two halves of the same image is not perfect, since the two images it takes are only slightly different from each other, and that little difference could make the image have a combing effect where it looks as if the subject is blurred.

Given this knowledge, there may be times when videos scanned with Interlacing may just be refused to be taken as the host or device just simply do not have that kind of tech anymore as it is not the standard.

I’ve read that Blender uses Interlacing, so that’s probably the cause. It may be set as the default somehow and you may simply just find a way to disable it. I’m not super technologically savvy but this is the best I could come up with.

Thank you so much for your answer, it clarifies a lot of things.

I have been using Blender extensively for three years on my main account, and never had this issue.
I doubt it's set by default, but it's worth checking nonetheless!

1080p, 1080i, whatever. This video is just really damn hot so I don’t care what the specs are they better not take this down again 😤

This animation vibes incredibly well with RCT2's Gentle Theme. Seriously, just try it.

That's getting super close.
However, the previous file was also progressive. Problem is that because the file is progressive and the video is interlaced, first frame every odd line updates, second frame every even line updates, third frame odd line, etc. etc. so when there's movement, you do get this artifacty look where literally every other line shows one frame and every other line shows previous frame, gives ghostly look to all movement.
Comparison, left is previous post, right is current post: https://puu.sh/KnqYH/2deb01b29a.png
Basically you have video that was made for CRT TV, then forcing it to be played on modern display with zero compensation (de-interlacing).

The main reason why these get deleted is because it's just, bad, zero care or knowledge taken to produce the file, which goes againts the guidelines that files need to be of high quality.
If it is super old video file, let's say VHS capture, then you should be at the very least deinterlacing it properly when converting to progressive video file and if it's modern 3D render from software like Blender... well, that straight up shouldn't happen to begin with!
Usually you see stuff like this when people share pirated content or badly edited stuff, not from author directly.

This is also one of those things where many people simply assume that this is how old videos looked, even though it's artifact from being converted incorrectly or badly from one format to another, just that it's impossible to show as how the video looks depents on your output device and the way CRT and LCD operates is completely differend. This is also problem when trying to convey problems with framerates, as your monitor can output say, 60Hz, refreshing 60 times per second, so if there's problem with two seperate videos framerates, I can't really do anything to show the difference clearly as it would show differendly depending on your monitors refresh.

With video editing, it's highly recommended to familiarize yourself with video editing stuff in general. I still remember when I had really old version of Sony Vegas, it would actually default to like 24 FPS interlaced timeline regardless what you were working with or needed and the very first step was to always change those things first. Got version 19 from Humble and that has been updated that it actually asks if I want to copy parameters of that input file for project finally.
Also because DaVinci is professional industry video editing tool, it wants to use commercial formats that are used in that space, where WebM is free web standard, so no money is exchanging hands and nobody uses those files directly, it's the web services like youtubes job to do that.

You should still be able to export into lossless intermediary formats from DaVinci and use something like FFmpeg (which Blender also uses) or Handbrake to then encode it into final VP9/Opus WebM for distribution.
Here's VP9 encoding guide if needed: https://trac.ffmpeg.org/wiki/Encode/VP9

I'm also unsure as to why you want to have the post as anonymous artist, when you are clearly in here in the comments commenting about how you have done this animation.

This was on purpose, as this kind of content does not fit the account I'm known for.

Just to sate your curiosity.

OK, that makes sense, just really weird to stay unknown/anonymoys, then interacting here, instead of just making fetish alt name or something.

I have the opportunity to not having another identity to manage, that is provided by e621 itself.
It also gives me the chance to potentially join them together in the future, if I happen to enjoy the idea.

Interacting with people is one of the best ways to get feedback, which I value a lot, with or without an artist name to be called with.

I genuinely don't see how this is weird...
But you are most definitely entitled to your opinion, and I respect it.

I also thank you for the help and detailed instructions you provided, they were undoubtedly useful!

Really makes me want to try making audio for this.

I guess this is what happens when your Koraidon loses to Sada's
