LTX's VFX tools are live on its API, with new Griptape nodes

LTX made its VFX capabilities available on the LTX API. They are Alpha Gen, SDR to HDR, Reframe and Upscale, for working on footage you already have.

Griptape, Foundry's node-based AI tool, added a node for each one and published a guide to using them. The jobs run in the cloud, so you don't need a high-end GPU.

LTX Alpha Generation turns a video into a greyscale matte, with an optional RGBA cutout encoded as ProRes with alpha. LTX SDR to HDR returns a 16-bit scene-linear EXR frame sequence and a 10-bit HEVC preview, with ACEScg, ACEScct, linear sRGB or ACES2065-1 as the EXR colour space. LTX Reframe re-crops a clip to another aspect ratio and generates the missing areas, placed by center, anchor or an exact rectangle.

LTX Upscale outputs 4K by default, with 1080p and 8K as options. Clips are capped at 2,401 frames for 1080p, 601 for 4K and 241 for 8K, and you're billed per second of input video at the rate of the output tier. The node checks a clip against those limits before it uploads or bills anything.

To get the nodes, update the standard library in Griptape.
