Frequently Asked Questions about Plexigen Ai

Does Plexigen generate the audio and sound effects, or do I need to add those separately?

Plexigen generates synchronized audio and sound effects as part of the video creation process, so you do not need to source or add them separately. The AI matches the audio to your video content and syncs it with lip movements for a finished product.

What do the credits on Plexigen's paid plans actually cover?

Plexigen does not publish a detailed credit cost breakdown for specific video lengths, models, or quality settings. Check their site before committing to a plan to understand whether your typical video needs fit within your monthly credits.

Can I export videos in portrait and square formats for Instagram and TikTok?

Yes. Plexigen supports landscape, portrait, and square formats, so you can generate videos optimized for different social platforms without having to reframe them afterward.

What AI video models can I choose from on Plexigen?

Plexigen runs on Google VEO 3.1 as its primary model, with Nano and Banana model options also available. The different models likely affect generation speed and quality, though Plexigen does not publish their specific differences or use cases.
