Release LTX Desktop 1.3.0 · Lightricks/LTX-Desktop

What's Changed

LTX Desktop has a new look across the whole app, with surfaces that match LTX.io.
The new Home page has a cinematic hero, a workflows gallery, a LoRAs row, and example media for each tool.
The new sidebar has Home, Assets, and Remote, with Featured tools, Recent workflows, and Recent projects.
Quick search (the / shortcut, the sidebar, or the Home search bar) finds any tool, with filters and previews.
Home, the Video Editor, Settings, Keyboard Shortcuts, and all dialogs now share one design system and one light or dark theme.
First-run is now one Setup screen for Hugging Face, API keys, and model downloads. It has an "Opt out of basic analytics" checkbox.
A new splash screen plays the LTX-2 end-page animation while the Python environment installs.
New back and forward navigation arrows in the header move you through the screens you visited.

Text to Video, Image to Video, and Audio to Video run locally, with a live results feed.
Audio to Video can record from the microphone on Windows and Mac, and trim long audio. It generates at 540p, 720p, and 1080p.
Retake and Extend accept a source of any length, have an optional Trim button, and blend the edited section into the original clip.
Pick a source video from the asset library when you use Retake, Extend, or an IC-LoRA.
Open a tool from a link with ltxdesktop://fetcher/{tool}.

New IC-LoRAs: Day to Night, Layout to Render, Restore, Deblur, Colorization, Clean Plate, Decompression, and Water Simulation.
New LoRA recipes, including Cozy Felt and Dolly In. Download a LoRA from the Generate button, or from Settings → Models.
Each LoRA now runs on the checkpoint it was trained for.

A global generation queue shows pending, running, Done, and Failed jobs. Drag a job to change its order.
A new Assets library shows your uploaded media and generated videos.
Your generations and assets now persist across restarts.

Text to Video, Image to Video, Audio to Video, Retake, Extend, the LoRAs, and the Assets library now work from the Remote app in any browser on the same Wi-Fi or local network (LAN), such as your phone.
Pairing is secure. The QR code gives a one-time grant, and the Remote page lists paired devices that you can revoke.

Local video now offers 270p and 360p, clips of 2 to 5 seconds, 25, 48, and 50 fps, and new aspect ratios: 21:9, 3:2, 4:3, 1:1, and 4:5. The model trained on 16:9 and 9:16, so other ratios can give lower quality.
Prompts are now enhanced automatically before local video generation. Turn this off with the auto-enhance switch, or use the Enhance button to enhance a prompt yourself.
Unlocked seeds are random. Every generate form has a seed control, and the seed is the same everywhere in the app.
The progress bar fills from the real denoise steps.
Local generation chooses full or streaming model loading for each job, and hides options that your machine cannot run.
A warning shows when 720p or higher is likely to be slow on a Mac.
A retake selection is limited to 10 seconds.

Settings has a clearer layout. The app now checks LTX, Fal, and Gemini API keys before it saves them, and you can remove a saved key.
The model upgrade dialog and the app update dialog now match the design system.

The app now uses ltx-core and ltx-pipelines 1.4.1, and the LTX API integration uses API v2.

Mac: LoRA runs no longer decode to green or gray frames.
Windows: IC-LoRA and Retake at 720p no longer use a very large amount of GPU memory on 32 GB cards.
Linux: a 32 GB machine no longer runs out of memory when it loads CUDA weights.
Mac: machines with 32 GB of total RAM are now correctly allowed to generate locally, and streamed model weights load faster.
Photos from phones, especially Android, no longer appear rotated by 90 degrees.
