Known Limitations

StarZero Agents is powerful, but it has boundaries. Understanding what it can't do helps you plan your projects and set realistic expectations. If you need a capability listed here, consider exporting your project to a traditional editor like Adobe Premiere Pro for those finishing touches.

Source and Project Boundaries

Short generated clips. StarZero Agents can generate video and images with AI, but each generated video is 3–10 seconds long. You can extend a shot up to 40 seconds in total, and restyles and edits work on up to 10 seconds of footage at a time. For longer sections, work through them in pieces.

Audio-only files have no picture to work with. Speaker detection, auto-reframing, and split-screen stacking all need a video track. Ask for them on an audio-only upload (an MP3, for example) and you'll get a clear explanation instead of a failed attempt.

Library selection locks after your first message. Once you begin a conversation, the content available to you is fixed. If you need to add more videos, start a new chat with the updated selection.

Editing Constraints

Limited external asset import. You can't bring in logos, sound effects, or arbitrary files from outside your library. External links still work for things that don't need to be searched — audio you want to extract from a URL, images, and font files — including free stock content through the Pexels plugin. A recording you want analyzed, searched, or cut goes into your library first: StarZero Agents will ask you to add it at StarZero via Add media (see Working From a Link).

Limited compositing. StarZero Agents supports overlays (picture-in-picture, images, SVG graphics, motion graphics) and flexible split-screen layouts (up to 12 panels in any grid arrangement), but does not support arbitrary multi-layer compositing. Split-screen is applied during rendering and is not yet previewable in the editor (coming soon). See Overlays for what's available.

No built-in transition effects. A very short crossfade is added automatically between clips to soften each cut, but there are no dissolve, wipe or longer fade effects to apply to a cut. For a designed transition, ask for a motion graphic stinger or bumper between clips, or a generated shot that bridges two scenes.

No reverse playback or time ramping. You can speed up or slow down clips (0.25x to 12x), but reverse playback and variable-speed time ramping within a single clip are not available.

No color grading or filters. LUTs, global color corrections, brightness/contrast adjustments, and visual filters are not available on your project. The one exception is footage framed inside a motion graphic, which can take on a colour look as part of the design.

No stabilization, blur, or masking. Motion stabilization, face blur, background blur, tracking, denoising, and masking effects are outside StarZero Agents's capabilities.

Graphics and Text

Designed graphics come as finished clips. Animated graphics such as title cards, lower-thirds, charts and kinetic text are designed for you as motion graphics: each one is a clip of up to about a minute, at up to 1080p and 30 fps, and overlay graphics are silent. To change a design, ask for a new version rather than editing it frame by frame.

Text overlays don't animate. Text overlays from the built-in presets appear and disappear, without fly-ins, typewriter effects, or per-character styling. For animated text, ask for a motion graphic.

Text overlay backgrounds are simple boxes. Text overlays start from a built-in style, and you can give them your own font, any text colour, and a solid or gradient background, with single words styled differently from the rest. The background is always a rounded box, around the whole text or one per line, so other shapes aren't available, and neither is styling individual letters. Motion graphics have no such limit: give them your brand colours and a font file, and the design follows them.

Rendering

Output quality depends on your source. StarZero Agents can't upscale low-resolution footage. If your source is 720p, your render won't look like 4K.

Fixed export settings. Renders use fixed export settings: you can't choose the codec, bitrate, frame rate, or color tagging, and StarZero Agents can't measure a render's loudness or bitrate for you. Lip sync, resolution, and playback compatibility are taken care of automatically on every render.

All video content must come from your library. Web research that StarZero Agents performs is informational only — it can't pull external media into your edit.

Operational

Your original files are never modified. StarZero Agents always works with copies. Your source content remains exactly as uploaded.

Analysis quality depends on available metadata. StarZero Agents's ability to find and understand your content depends on the quality of transcripts and visual descriptions available. Some content may have richer metadata than others.

Working Around Limitations

Many of these limitations can be addressed by exporting your project:

• After rendering, click Download project files to get a file you can open in Adobe Premiere Pro
• In Premiere Pro, you can add transitions, color grading, overlays, reverse playback, and any other effects
• This workflow gives you the best of both worlds: StarZero Agents's AI-powered searching and assembly, plus traditional editing tools for finishing
