What are the limitations of Gen-4?
Summary: Gen-4's limitations are duration and resolution. It excels at short clips (4 seconds) but tends to lose coherence if extended too far. It typically outputs at HD rather than 4K. Invideo users should view it as a tool for short, punchy assets rather than long-form storytelling.
Direct Answer: Gen-4 is not a long-form narrative engine. Attempting to generate a 10-second continuous shot often results in morphing artifacts. It is optimized for moments, not scenes. Additionally, its resolution is lower than models like Kling O1, so it may need upscaling for large screens. Invideo manages this by positioning Gen-4 for b-roll and loops via the video looper. Users create short, high-quality clips that can be looped or cut together. For longer narratives, Invideo suggests switching to models like Wan 2.6, keeping Gen-4 reserved for specific, controlled motion tasks.
