Tried to upload a video today. Totally distorted. Why???
I can play videos of any size on my smartphone. Why not here?
Not amused :)

Has to be 16x9 wide to upload here or it distorts.

I noticed that.
That’s a very unfavorable format for typical AI videos. The videos people want to watch here need a portrait orientation.
With 16:9, there’s too much around the edges that isn’t in focus but still has to be rendered. That costs VRAM, time, and processing power. With a consumer graphics card that typically has 8, 12, or 16 gigabytes of VRAM, a video would only be 300 to 400 pixels high. And it would still take forever to render.
If you look at Civitai, for example, you can see what’s possible today with consumer hardware. Renderotica would benefit massively from this. Because the kind of material you’re allowed to publish here isn’t allowed on typical AI sites.

16 x 9 is a typical cinematic format (HDTV). Its by far the most widely use content production format. Netflix _requires_ content to be delivered 16:9, for example. As a result its also where we have the most training data. genAI video models have far more training data in this aspect ratio than others. Kling, Veo, Seedance, LTX . . . all are fantastic at 16:9.
When you get to a portrait style aspect ratio, the real world training data comes from stuff like TikTok videos (which Seedance in particular has seen a lot of, obviously).
But those aspect ratios give you a lot of the "one girl doing very little" stuff that make AI dull. Yeah, she's pretty and she's dancing and . .. we've seen 8 billion of those.
Getting people interacting, doing interesting things rather than just facing the camera . . . there's much, much more training material in widescreen format, much more opportunity for real storytelling in 16:9

Yes, there is a lot to be said for the tried-and-true techniques and methods of the good old days. New developments, such as AI, don’t benefit from this at all. The trend toward portrait format (see Civitai, one of the most important sites regarding generative AI) is due to the fact that consumer graphics cards have limited computing power. If you use a full cinema format like 16:9, too much “around the edges” has to be calculated. Furthermore, the vertical format has even made its way into short videos on public television. Renderotica can only win if it embraces this trend. No matter what or how: AI-generated video sequences can be produced more easily, quickly, and cheaply in the vertical format (again, a reference to Civitai’s video section: https://civitai.com/videos).

Completely agree. Widescreen introduces a lot of dead space that needs to be filled. Some scenes lend themselves to widescreen, many don't. Portrait format actually can benefit if you are starting out in Daz and moving to Ai as there is less area to be filled with VRAM consuming props and textures. Seems a bit odd that only widescreen formats can be uploaded here without distortion.
