Character & Object Editing

With Runway Aleph AI video editor, users can instantly add/modify/remove characters and objects in any given frame. Instead of manual masking, all it takes is a simple prompt like ‘add green suitcase’ or ‘replace the cat with a dog’, with various aspects like scale, perspective, reflections, lighting, etc, taken into account for seamless scene changes.

Camera Angle Modification

Runway Aleph lets users generate new camera perspectives across scenes by simply prompting what they want. Whether it’s aerial shots, tracking shots, close-ups, zooms, wide-angles, etc, the AI model can simulate alternate viewpoints to offer greater cinematic control that doesn’t require the use of multi-camera setups.

Transparent Background Compositing

Using the Runway Aleph AI video editing model, it becomes easy to isolate and extract specific subjects or objects in any scene with pixel-level precision. These green-screen cutouts with transparent/solid backgrounds can then be composited into different environments, allowing users to create entirely new visual sequences without complex editing expertise.

Runway Aleph can extend any existing footage by seamlessly adding extra frames based on the user’s prompt instructions. Just describe what you want to see happen next, and the AI model will generate the next frame with a natural and flawless transition, making it possible to save time producing longer visual narratives.

Easy to use, great results for short videos
I’ve been using Pollo AI mainly for short videos and quick image-to-video tests. The interface is straightforward and it works well even with simple prompts, which is a big plus compared to tools that need long, complicated instructions. The results can be really impressive, and it’s honestly been fun to experiment with. I’d love a bit more consistency on faces when there’s movement, but overall it’s been a solid experience for what I needed.

Awesome website
Awesome website. loads of options and a great way to learn how to work with 'AI' my reasoning for 5 stars is based upon price, versatility and ease of use. Also I would like to add, Pollo AI runs a lot of promos on different AI products as well. I rate their customer service at 5 stars, when I purchased my first subscription my computer crashed the following weekend and I lost all my data and info passwords you name it I lost it, contacted pollo by email they responded quickly and found my info/username and account, and I was able to restore my account.

I have been using Pollo AI for short videos. It is easy to use and works well with simple prompts. Other generators seem to need long drawn out complicated explanations to get even close to what I want.
