Extend the composition around your shot for a different aspect ratio. **WORKFLOW ACCESS** Reframe API node in ComfyUI. ### AlphaGen **CAPABILITY** Prepare alpha for compositing, including partial transparency and fine edge detail, with full-resolution output up to 4K. **WORKFLOW ACCESS** Open weights and LoRAs for alpha workflows. ### SDR to HDR **CAPABILITY** Convert SDR footage for HDR finishing. The new output uses ACEScct with AP1 primaries, rather than the earlier LoRA’s ARRI LogC3 with Rec.709. **WORKFLOW ACCESS** Open weights and LoRAs for HDR workflows. ### Upscale **CAPABILITY** Bring footage to 4K or 8K, with raw-file handling for a finishing pipeline. **WORKFLOW ACCESS** Open weights and LoRAs for upscale workflows. | | CAPABILITY | WORKFLOW ACCESS | | --- | --- | --- | | Reframe | Adapt existing footage to a new frame.

STEP 01 Start with your footage Choose the clip and finishing task your shot needs. 2. STEP 02 Choose the feature workflow Use Reframe through its API node, or build with the open weights and LoRAs for alpha, HDR, and upscale tasks. 3. STEP 03 Review and finish Check the framing, edges, color pipeline, and output settings before passing the result downstream. ## LTX VFX questions, answered. These are task-specific VFX workflows for working with existing footage. Choose the workflow for Reframe, AlphaGen, SDR to HDR, or Upscale rather than a text-to-video or image-to-video generation template. Reframe is the new API-node integration. Alpha, HDR, and upscale workflows can use open weights and LoRAs. API support and output options vary by feature; check the feature’s documentation rather than assuming every workflow has the same API access. See the [Reframe API reference](https://docs.ltx.io/api-documentation/api-reference/async-video-generation/submit-video-to-video-reframe) for its inputs and output options. The newer SDR to HDR output uses ACEScct with AP1 primaries. The previous LoRA used ARRI LogC3 with Rec.709. Match the input transform in your grading or compositing tools to the workflow you run. ## Choose a plan Access cloud-powered ComfyUI workflows with straightforward, usage-based pricing.

It has been amazing to watch technical artists and curious creative minds leverage Comfy to explore the full surface area of their ideas."
