Sulphur-2 video tutorial

The Sulphur-2 bundle now has a full walkthrough on the Docs page — just under eight minutes, in English, Russian and Chinese, with subtitles.

It covers the LTX Director workflow end to end:

• Image → video — make a person in a photo say the text you give it.
• Image + audio → video — feed a voice clip you prepared in Fish Audio S2 and have the person in the picture speak that exact recording.
• Extending a clip — put an existing video at the start or the end of the timeline and let the model generate the missing part. Match the framerate of your source, or the result drifts.
• fp8 vs bf16 — these are different models, not quality presets. fp8 is the compressed one: lighter on resources, weaker results.

Also covered: why to test on a short time span before committing to a full render, why splitting prompts into short intervals generates more accurately, and how the wrong duration makes the model hallucinate. The voice itself can be replaced afterwards with CosyVoice3.
