This page therefore does not label one as universally better: the table shows compatible inputs, limits and pricing, while the visual section separates valid A/B checks from different workflow stages.

Topaz Video Upscaler: Enlarge a clip you have already selected without generating the scene again. Start with the specification table: it reflects current modes, input media, duration, resolution, aspect ratios and a normalized price where a fair comparison is possible. ## Specifications | Spec | MiniMax H3 | Topaz Video Upscaler | Generation modes | from text / from first and last frames / from references | — | First frame | Yes | No | Last frame | Yes | No | Input photos | up to 9 | No | Input videos | up to 3 | No | Input audio files | up to 3 | No | Input video length | 2–15 s | No | Input audio length | 2–15 s | No | Output audio | Native | No | Minimum duration | 4 s | — | Maximum duration | 15 s | — | Resolutions | 768p / 2K | 1x / 2x / 4x | Aspect ratios | 9:16 / 16:9 / 1:1 / 4:3 / 3:4 / 21:9 | Follows the input | Prompt limit | 7,000 characters | 0 characters | Price, 1 s (different quality) | ≈ 10.63 coins · 768p | ≈ 5.93 coins · 1× There is no shared resolution for a direct price comparison, so each price includes its setting and is not highlighted as cheaper. ## What to compare visually Do not force tools with different jobs into the same test. First compare the inputs each one accepts and the output it is meant to produce. If they share a workflow, run an A/B test on the same source; otherwise judge each at its own stage: generation, Motion Control, avatar creation or upscaling. ## What to inspect with MiniMax H3 Build a scene from separate references for appearance, movement and sound. - Text mode, one or two frames, or references. - Up to 9 images, 3 videos and 3 audio files. Video and audio each have a separate 15-second total limit; audio needs a visual reference. - The first five images are included in the base calculation; additional images increase the price. - Input video adds billable duration. Check the total, not only the resolution. ## What to inspect with Topaz Video Upscaler Enlarge a clip you have already selected without generating the scene again. - 1× processes without enlarging; 2× and 4× multiply the frame dimensions. - One MP4, MOV or MKV file, up to 50 MB on the website. No prompt required. - A 4× scale does not recover true detail that never existed in the source. - Upscaling does not correct the story, pose or incorrect object movement. ## How to run a fair comparison - Identify the workflow stage first: create new media, transfer motion, make a talking avatar, or improve an existing file. - Compare specifications only where they mean the same thing: accepted inputs, limits, available resolution and the real price of the needed mode. - If a shared workflow exists, use the same source. If it does not, do not infer visual quality from non-equivalent outputs. - Tools for different stages can be used sequentially rather than as substitutes. ## What we compare [ MiniMax H3 Build a scene from separate references for appearance, movement and sound. ](https://mixerai.org/en/knowledge/video/minimax-h3/)[ Topaz Video Upscaler Enlarge a clip you have already selected without generating the scene again. ](https://mixerai.org/en/knowledge/video/topaz-video/) ## FAQ How should I compare MiniMax H3 and Topaz Video Upscaler fairly? Compare purpose and inputs first. Test any shared workflow on the same source; evaluate different workflows separately by output quality, constraints and the price of that stage. Are both models available in Mixer AI? Yes. This page is generated only for models in the current public Mixer AI catalog; if a model leaves the catalog, the automated comparison must stop passing validation. Which model is better? There is no universal answer. First eliminate a model that cannot accept the input, duration, resolution or format you need, then compare outputs on your own scene. The table highlights only measurable advantages in individual specifications. ## See also [MiniMax H3 vs Seedance 2.5: model comparison→](https://mixerai.org/en/knowledge/compare/minimax-h3-vs-seedance-2-5/)[Veo 3.1 vs MiniMax H3: technical and visual comparison→](https://mixerai.org/en/knowledge/compare/veo-3-1-vs-minimax-h3/)[Veo 3.1 vs Topaz Video Upscaler: technical and visual comparison→](https://mixerai.org/en/knowledge/compare/veo-3-1-vs-topaz-video/)[Kling 3.0 vs MiniMax H3: technical and visual comparison→](https://mixerai.org/en/knowledge/compare/kling-3-0-vs-minimax-h3/) [Try it on Mixer AI](https://mixerai.org/?dl=kb_minimax-h3-vs-topaz-video#/canvas)
