Single stage #LTX reframe workflow in @ComfyUI at 297 seconds using a custom Reframe node. The output video quality isn't as good as it can be, but an additional second refinement stage may fix this.

3D Gaussian Splattingの新しい見せ方を作りました。その名も Inversphere.
2Dのリトルプラネットと違い、空間ごと球面反転しています。ガラス玉に入れる従来の見せ方は球で「切り取る」のに対して、これは球の中へ「折り込む」ので360度の景色が無限遠まで立体で入っています。

And it shipped right. Example files, pre-toggled settings, real VRAM numbers from actual testing.

Your first run matches his demo exactly.

@robinjhuang @robinjhuang Thanks a ton for the shoutout, Robin! Super happy you see the value in it. 🙌

In AI video gen you spend more time describing your reference than actually generating.

Someone just fixed that.

ComfyUI Native 3D Camera Node.

Adding intuitive controls to the camera node.
Actually, this node wasn’t added by me, it was put in by KJ (yes, the KJ everyone knows) while he was working on TripoSplat.

That said, KJ only built the backend and a basic numeric panel. Honestly, after trying it out, I felt that no one is really going to adjust the camera’s position and view angle through such an unintuitive method.

So a visual 3D camera adjustment became an inevitable choice.

This is actually somewhat similar to my Qwen multi-angle camera plugin, but this native implementation is far more complex than that one. There are three camera modes alone, by comparison, my Qwen camera plugin is really just a special case of one fixed viewpoint under the orbit mode.

Starting from this point, ComfyUI core’s 3D-related nodes are no longer just the load/preview model series, there may be more features along these lines that use 3D scenes for control. This is exactly why I insisted on preparing ahead of time by working on that “unlocking unlimited 3D node additions” thing I posted about earlier.

It’s still a WIP, and I have no idea when it’ll get merged in.

SCENA by Lightricks.
Reference-driven multi-speaker audio scene gen!
Prompt "two friends arguing in a rainy cafe" + two ref voice clips -> full 20s audio scene in one pass.
Overlapping speech, room echo, background sounds - all baked in.
- based on LTX-2.3
- beats ZipVoice-Dialog/MOSS-TTSD
- up to 3 ref speakers
- perfect text alignment
-Identity-aware positional encodings
- SOTA performance

We gave a coding agent a goal and a time budget: build a training environment and teach a vision model to count colored stars.

Using autoresearch with NeMo RL, NeMo Gym, and reusable skills, the agent set up, trained and evaluated the model while the researcher steered the work.

Qwen3-VL-2B went from 25% to 96.9% accuracy, and the agent even proposed the next experiment on its own.

"SAM2Matting: Generalized Image and Video Matting"

TL;DR: upgrades foundation video trackers like SAM2 into state-of-the-art image and video matting models by decoupling temporal tracking from fine-grained alpha estimation achieving zero-shot video matting without video training

@AlexshevPm @ComfyUI That's the dream! Crazy part about this is that it's basically a standard in-paint/out-paint workflow by LTX that's been available all along. A single additional node makes all the difference for better control.

Working on a new #LTX Reframe Node for @ComfyUI!

It lets you intelligently adjust video framing, aspect ratio, and subject positioning while keeping the content intact.

Output is still pretty rough (needs some LTX-side tweaks), but the node itself is working!

🎉Demo in the video
📷Feedback or tips appreciated!

Most reframe tools crop, downsize, or hallucinate.

Introducing the LTX Reframe API.

Expand any video to a new aspect ratio. The original frame stays untouched. The model generates only what’s beyond the edges.

• Full source length, up to 60s
• Native 1080p
• 16:9, 9:16, 1:1, 4:5
• Built on LTX-2.3

One master reframed for every placement.
