Outputs and behavior

Render a local video/GIF or still image/cached template to H.264 MP4 (AAC when source has audio), optionally a companion GIF. Requires myzing[memes], FFmpeg and ffprobe. No network. Maximum selected duration 30s; trim with source start/end. Still duration defaults to 5s; zoom is 0..0.25. Layouts and text caps match meme_render. at/until arrays give one inclusive output-time window per text, relative to the trimmed clip. GIF limits: 8s, 10fps, 640px wide; parameters may lower these. Existing outputs require overwrite=true. Returns paths, dimensions, durations, byte sizes and text boxes, never media bytes.

The tool description documents its results and behavior. An exact output schema is not supplied; fields not described here are unknown.

What touches the network

From this tool's description:

No network.

Network behavior beyond these details is not specified in the tool description.

Zing's network policy

Studying, rendering and memes run locally by default. Reference URL downloads require explicit consent. Requested model and font downloads are pinned by URL and SHA-256, cached locally and reported. Uoink is reached only through a peer you configure on your machine. Zing has no telemetry or analytics.
