OpenAI adds reusable ‘characters’ and video stitching to Sora

Sora can turn almost anything into a reusable AI video character.

OpenAI’s Sora app will now let you turn almost anything into a reusable avatar for its AI-generated videos. These “character cameos” are one of several new features that have been added to the Sora 2 video generator, alongside clip stitching and leaderboards that showcase the app’s most popular videos and cameos.

Character cameos were teased last week, and build on the existing feature that allows Sora users to create AI deepfakes of themselves that can be used by everyone else on the platform, if permitted. Those same capabilities can now be used on other subjects, such as pets, illustrations, and toys, and the feature is launching with a selection of pre-made characters that users can add to videos.

“Once created, each character comes with its own permissions, separate from your personal likeness: keep it just for yourself, share it with mutual followers, or open it to everyone on Sora,” OpenAI says in the latest Sora release notes. “Give your character a display name and handle, and tag it whenever you want it to appear in a video.”

OpenAI says that character cameos can be created using “an original persona” that users generate in Sora, but it’s unclear if the feature will accept fictional people generated using other AI tools, or how photorealistic they’re permitted to be. If you can just upload any AI-generated person, OpenAI hasn’t explained how Sora would distinguish these from images of real people. The update is being launched within days of celebrity video platform Cameo slapping OpenAI with a trademark infringement lawsuit over its usage of “cameo” in Sora app features.

Sora is also introducing video stitching capabilities that can connect multiple videos together to create longer, multi-scene clips, and leaderboards that show the most remixed videos and the most cameoed users and characters. OpenAI has temporarily made the Sora app more accessible to get people using these features, announcing yesterday that people in the US, Canada, Japan, and Korea can sign up without an invitation code for a “limited time.”

Pandora Stories lets artists add commentary to their own playlists

Pandora launched Stories today, a tool that lets artists and creators add voice commentary to their own playlists.

The feature is part of Pandora AMP, the streaming service’s free Artist Marketing Platform that helps creators promote their work. To kick off the launch, Pandora’s prepared some Stories by artists like John Legend and Daddy Yankee, who tell listeners their personal stories interspersed between their own songs. There’s also a Stories playlist called Love Songs That Aren’t Really Love Songs , which includes commentary on individual songs like a podcast...

Instagram’s updated algorithm prioritizes original content instead of rip-offs

Image: Kristen Radtke / The Verge Instagram is making significant changes to how its system recommends content, with a focus on original content and increased distribution for smaller accounts. The slew of changes were announced by the company in a blog post today. The biggest change deals with aggregators — accounts that download or screenshot other users’ videos and photos and repost them. Sometimes aggregators will credit the original poster by tagging them in the post or caption, but often, content is wholesale ripped off with no acknowledgment, and engagement is siphoned off from the person who created the content in the first place. Instagram clearly has a problem with this and will begin removing reposted content from recommendations across the platform. The... Continue reading… from The Verge - All Posts https://ift.tt/ECgcPAU

We asked camera companies why their RAW formats are all different and confusing

When you set up a new camera, or even go to take a picture on some smartphones, you’re presented with a key choice: JPG or RAW? JPGs are ready to post just about anywhere, while RAWs yield an unfinished file filled with extra data that allows for much richer post-processing. That option for a RAW file (and even the generic name, RAW) has been standardized across the camera industry — but despite that, the camera world has never actually settled on one standardized RAW format. Most cameras capture RAW files in proprietary formats, like Canon’s CR3, Nikon’s NEF, and Sony’s ARW. The result is a world of compatibility issues. Photo editing software needs to specifically support not just each manufacturer’s file type but also make changes for each new camera that shoots it. That creates pain for app developers and early camera adopters who want to know that their preferred software will just work. Adobe tried to solve this problem years ago with a universal RAW form...
