Duration, Resolution & Quality

Supported video durations, resolution options from 720p to 4K, per-model availability for both settings, and how they affect credit cost and output quality in Qolaba's Video Generation workspace.

Duration and resolution are the two output settings with the greatest combined impact on visual quality and credit cost. Understanding how they interact helps you iterate efficiently and spend credits where they matter most.

Video Duration

Duration controls the length of the generated video in seconds. Available options vary by model.

Supported Durations

Duration	Credit Cost	Best For
1 second	Lowest	Quick cuts, looping visuals, seamless transitions
4 seconds	Low	Short social clips, product moments, cut-ins
6 seconds	Moderate	Social media content, brief narrative scenes
8 seconds	Higher	Cinematic scenes, product demos, full storytelling moments

Resolution & Quality

Resolution controls the visual fidelity and pixel density of the generated video. Higher resolution produces sharper output — and costs more credits per generation.

Available Resolutions

Resolution	Credit Cost	Best For
720p	Lower	Draft generation, concept testing, prompt validation
1080p	Standard	Social media, client delivery, standard distribution
4K	Higher	Commercial production, broadcast, high-fidelity output

Choosing Duration and Resolution Together

Duration and resolution compound in their effect on credit cost and should be decided together.

1. For testing and iteration: Start at 4 seconds + 720p — the most credit-efficient configuration that still produces a meaningful output to evaluate. Motion quality, prompt adherence, composition, and style are all clearly visible at this setting.

2. For standard final delivery: Move to 6–8 seconds + 1080p once your prompt and model are confirmed. This covers most social media, client, and digital distribution requirements.

3. For high-production final output: Use 8 seconds + 4K only for confirmed final outputs destined for commercial, broadcast, or large-screen delivery. Credit usage is significantly higher — never use it for testing.

A 720p draft followed by a single 4K final generation is far more credit-efficient than generating at 4K from the start. Validate direction first, then upgrade resolution for the final output only.
