Cons

Premium features are locked behind a subscription that can feel expensive for casual creators who only need occasional access to advanced AI tools like eye contact correction.
The automatic editing AI sometimes removes pauses and moments that the creator intentionally included for dramatic effect, requiring manual review and adjustment.
Video export quality and resolution options are limited on the free tier, with watermarks on outputs that may not be suitable for professional publishing.

Requires significant technical knowledge to install, configure, and optimize, with a steep learning curve that can be overwhelming for beginners compared to simple web-based tools like Midjourney.
Local generation requires a capable GPU (8GB+ VRAM recommended) for reasonable speeds, which means additional hardware investment for users without existing gaming or workstation computers.
Base model output quality, while good, typically requires careful prompting, negative prompts, and post-processing to match the consistently polished aesthetic that Midjourney produces with minimal effort.
