Testing out Stable Diffusion inpainting on a video

@justLV
For this concept, I was inspired by the work of @model_mechanic - I wanted to try combining this concept with live action footage to interact with a real physical object

The inspiration video:

1/ Now you can create "drone" shots from your phone footage, thanks to NeRF
Collab with @justLV / software @nerfstudioteam / see below for our process
#NeRF #neuralrendering #artificialintelligence #instantNeRF
2/ Here is the raw footage input (sped up 5x here) which we fed into NeRF Studio
3/ Then @justLV created a camera path inside NeRF studio.

The grey polygons are keyframes, the red line is the path that @nerfstudioteam auto-generates to smooth out the camera path

1/ Using AI to generate fashion

After a bunch of experimentation I finally got DALL-E to work for video by combining it with a few other AI tools

See below for my workflow -

#dalle2 #dalle #AIart #ArtificialIntelligence #digitalfashion #virtualfashion
2/ First I used DALL-E to generate outfits. I did this by erasing parts of my existing outfit and inpainting over it

Btw when I erased the entire outfit, the results didn't look as good. By keeping parts of the original, DALL-E was able to better match color and lighting
3/ But here’s the challenge. DALL-E works great for individual pictures, but it’s not designed for video. It won’t give you consistency from frame to frame.

Here was my early experiment. See, no consistency between frames

1/ Using AI to imagine alternate worlds🪞
collab w/ 🍃@MichaelCarychao 🦾Sagans

#discodiffusion #aiart #artificialintelligence
@MichaelCarychao 2/ Here's the raw footage. I started off by creating a simple AR filter of two empty white rectangles using Adobe Aero. Shot by @AustinGumban
@MichaelCarychao @AustinGumban 3/ Then @MichaelCarychao generated the nature side. Here's a peek at his behind-the-scenes process. Highly recommend checking out his account for more AI art ideas

1/ I used DALL-E to imagine beyond this painting @OpenAI Inspired by @literallydenis #dalle #dalle2 #artificialintelligence #art
@OpenAI @literallydenis 2/ Something that AI headlines don't always capture is that as a human, you actually have a lot of artistic input in what the AI paints. The AI didn't draw all this automatically - I prompted it to draw certain elements
@OpenAI @literallydenis 3/ Here's a sampling of the prompts I used. For each prompt, I added "painting by Johannes Vermeer" at the end for style Image

1/ Using AI to smooth my footage 😌 with @jperldev. We’re using DAIN, an AI technique that smoothly interpolates frames. #stopmotion #artificialintelligence
2/ For every frame you see, it generates 8 frames in between with incredibly smoothness and accuracy. Its main use case is to create artificial (and very convincing) slow motion on clips, but I thought it'd be interesting to apply it to stop motion to create "impossible" movement
3/ You can try DAIN by going to grisk.itch.io/dain-app. It works on Windows and NVIDIA only (it requires a TON of GPU power) and isn't the easiest to set up or run. But I do believe that this technology will become more mainstream

1/ We used NeRF to get this shot. This entire thing was shot with a phone 🤳 No drones were used @jperldev #photogrammetry #instantNeRF #neuralrendering #artificialintelligence
2/ Here's how - walked around me in circles a few times, pointing his phone at me. We fed the video into Instant-NGP which created a NeRF out of the footage.
3/ It's kinda like a 3D model, but instead of creating mesh+textures it’s more like a point cloud that changes color depending on what angle you view it from. This creates beautiful surreal lighting effects - you can see how the light hits differently as we change camera angles.
