LTX Studio API v1 enhancements:

• Added veo3-fast model support to POST videos/veo-create for faster text-to-video generation
• Enhanced audioSFX parameter support across all Veo models (veo2, veo3, veo3-fast) for automatic sound effects generation
• Added shotType and shotAngle parameters to Flux image endpoints for enhanced composition control:
  • POST images/flux-create
  • POST images/flux-edit
• Extended LTX video duration options to include 15 and 30 seconds in POST videos/ltx-create

Example
