Video Runtime

This page covers the native video-generation path exposed through mere.run video.

Public surface

• mere.run video generate
• mere.run video export-latents

Model family

• video-ltx-av

Typical workflows

Generate video

swift run mere.run video generate \
  "a cinematic drone flythrough over snowy mountains" \
  --variant unified-av \
  --model-root ~/Library/Application\ Support/MereRun/models/video-ltx-av \
  --output ./clip.mp4

Export latents

swift run mere.run video export-latents \
  --prompt "storm clouds over the ocean" \
  --output ./latents.npz

Runtime entrypoints

CLI

• Sources/MereRunCLI/Commands/VideoGenerateCommand.swift

Runtime

• Sources/MereRunCore/LTX/LTXDistilledLatentGenerator.swift

Important note on code shape

The LTX runtime is still the largest major runtime file in the repo. It is not an architecture mess anymore, but it still contains more low-level video-model logic than the other family entrypoints.

The best reading order is:

1. public generation types and LTXDistilledLatentGenerator
2. request normalization and generation flow
3. denoise and latent-conditioning helpers
4. decoding and media assembly code
5. lower-level model definitions

If you are new to the repo, use Architecture Reading Map before diving directly into the LTX implementation.
