What's Changed
New IC-LoRAs
- Refine Details: rebuild fine detail in a soft, compressed, or upscaled video. It offers 1440p and 4K.
- Turn on Settings → General → Show advanced controls to tune tile overlap, chunk carry, maximum chunk length, and tile size.
Custom LoRA
- Add your own LoRA from a local
.safetensorsfile or a Hugging Face link. Use Add custom LoRA in the sidebar. - Each saved LoRA has its own page with video controls and a strength slider.
- In Settings → Models, Delete removes the weights and keeps the entry. Remove deletes the entry.
More control over generation
- Text to Video, Image to Video, Audio to Video, Retake, Extend, the LoRAs, and the IC-LoRAs now have a Negative prompt field for local generation. Set the strength in Settings → General → Generation.
Memory and long clips
- A clip that does not fit in one pass now runs in overlapping parts. Before, LTX Desktop refused it. This applies to Text to Video, Image to Video, Audio to Video, and the LoRAs, at every resolution.
- On Windows, smaller graphics cards now offer longer 1080p clips. A 12 GB card offers up to 10 seconds. 16 GB and 24 GB cards offer up to 20 seconds.
- A notice tells you when a clip runs in parts. Parts take longer, and lighting or subjects can drift between them.
- A new Make it choice sets All at once or In parts for each clip. The options show their memory use.
- A job that needs more memory than your computer has, or that nobody tested on a machine like yours, is no longer blocked. LTX Desktop asks Generate anyway? first, because the job can run out of memory or slow your computer.
Time estimates
- Next to Generate, the form shows the estimated time. The estimate learns from your own runs on your machine.
- While a local generation runs, the Queue row and the result card show the time remaining. GenSpace shows it during denoising.
Queue and Assets
- Choose the folder where LTX Desktop saves your assets in Settings → General → Assets folder. Existing assets move to the new folder.
- Every feature page now shows all your results. Before, it showed only the 10 newest. Each page remembers your scroll position during the session.
- LTX Desktop asks before it deletes a result or cancels a generation. Select Don't ask me again to turn this off. You can turn it on again in Settings → General → Confirmations.
- Image pickers now open the asset library, filtered to images.
Engine
- The app now uses
ltx-coreandltx-pipelines1.6.0.
Bug Fixes
- Mac: Video Guide with Pose no longer fails when it loads the DWPose model.
