Key Takeaways:
  • LTX Studio now includes Topaz video upscaling natively, letting you enhance AI-generated video up to 4x resolution with controls for FPS, codec, and quality — no external tools required.
  • Topaz delivers the highest quality detail recovery for client deliverables, broadcast, and large-screen output; Z-Image is the faster, cheaper option for iteration and social content.
  • Best practice is to generate and iterate at native resolution, then upscale only your final selected clips with Topaz before delivery to preserve speed and credit efficiency.

AI-generated video has a resolution problem. Most video generation models produce output at 720p or lower, which works for early-stage exploration and internal review but falls short of what professional production requires. Marketing assets, client deliverables, social media content, and broadcast material all demand higher resolution and sharper detail than raw AI output typically provides.

That is where AI video upscaling comes in. LTX Studio now includes Topaz video upscaling as a built-in capability, which means you can enhance the resolution and quality of your generated videos without leaving the platform. No external tools, no export-import cycles, no separate subscriptions.

This guide covers how Topaz video upscaling works in LTX Studio, what settings to use, and how to decide between Topaz and Z-Image for different production needs.

What Is AI Video Upscaling?

Video upscaling increases the resolution of a video beyond its original dimensions. Traditional upscaling uses interpolation, which essentially guesses at the pixels between existing ones. The results are smoother but not sharper. Details that were not captured in the original footage cannot be recovered through interpolation alone.

AI video upscaling works differently. Instead of interpolating between existing pixels, AI models analyze the content of each frame and generate new detail that is consistent with what the frame depicts. Textures become sharper. Edges become cleaner. Fine details like fabric patterns, skin texture, and environmental elements are enhanced in ways that interpolation cannot achieve.

For AI-generated video specifically, this distinction matters. Generated footage often contains soft areas, subtle artifacts, or resolution limitations imposed by the generation model. AI upscaling addresses these by intelligently adding detail that the generation model did not produce at the original resolution.

Why AI Videos Need Upscaling

Every video generation model in LTX Studio produces output at a native resolution that may not match your final delivery requirements. A 720p generation looks fine on a small preview but loses impact on a full-screen presentation, a 4K display, or a broadcast delivery pipeline.

The practical pattern for most production workflows is: generate at the model's native resolution to iterate quickly, then upscale the final selected output to your delivery resolution. This approach optimizes both speed (fast generation at lower resolution) and quality (polished output at final resolution). Upscaling is the bridge between raw AI output and production-ready delivery.

Topaz Video Upscaling in LTX Studio

Topaz Video AI is a widely used upscaling technology known for producing high-quality results across different content types. Within LTX Studio, Topaz video upscaling is integrated directly into the platform, so you can upscale your generated videos as part of the same workflow where you create them.

How to Access Topaz Video Upscale

Topaz video upscaling is available in LTX Studio to users on applicable paid plans. To upscale a video:

• Generate your video using any model in the Gen Space

• Select the generated video you want to upscale

• Access the upscaling options from the Tools menu

• Choose Topaz as your upscaling method

• Configure your upscale settings (resolution multiplier, FPS, codec)

• Run the upscale

The upscaled video appears in your workspace alongside the original, so you can compare them directly before proceeding to editing or export.

Topaz Upscale Settings Explained

LTX Studio's Topaz video upscale offers several controls that affect the output quality, file size, and processing time:

Resolution multiplier: Topaz supports up to 4x upscaling. A 720p source video at 2x becomes 1440p. At 4x, it reaches near-4K resolution. Higher multipliers produce sharper results but require more processing time and credits.

FPS controls: You can adjust the frame rate of your upscaled output. This is relevant when your source video was generated at a frame rate that does not match your delivery requirements. For example, if your delivery pipeline requires 24fps and your source is at a different rate, FPS controls let you match the target without a separate transcoding step.

Codec settings: LTX Studio provides codec options for your upscaled output. These settings affect file size, compatibility, and quality preservation. For web delivery, standard codecs keep file sizes manageable. For broadcast or post-production handoff, higher-quality codec settings preserve maximum detail through the rest of your pipeline.

Granular quality slider: Fine-tune the upscale intensity to balance between sharpness and naturalness. Higher settings produce more aggressive enhancement, while lower settings preserve the original character of the footage with subtle improvements.

Topaz vs. Z-Image: Which Video Upscale to Choose

LTX Studio offers two upscaling options for both images and video: Z-Image and Topaz. Each has distinct strengths:

Z-Image is faster and more affordable. It produces good results for content where speed matters more than maximum fidelity. Social media content, internal reviews, and rapid iteration all benefit from Z-Image's processing speed and lower credit cost.

Topaz delivers higher quality and more accurate detail enhancement. It is the better choice when the output is client-facing, going to broadcast, or needs to hold up at large display sizes. The tradeoff is slower processing time and higher credit cost per upscale.

The decision framework is simple: if speed and cost efficiency matter most, use Z-Image. If quality is the priority, use Topaz. For many projects, you will use both at different stages: Z-Image during iteration and review, Topaz for the final delivery version.

Upscaling to 4K and Beyond

From 720p to 4K: What to Expect

Upscaling from 720p to 4K is approximately a 4x resolution increase. At this multiplier, Topaz adds significant detail to every frame. Textures that appeared soft at 720p become defined. Edges that were slightly blurred become crisp. The result is footage that can stand alongside natively-shot 4K content in a professional edit.

However, the quality of the upscale depends heavily on the quality of the source. A well-composed, well-prompted generation with clean detail at 720p will upscale beautifully. A generation with artifacts, noise, or compositional issues will have those issues enhanced along with the detail. Upscaling amplifies everything, including flaws. The practical takeaway: invest time in getting the best possible generation before upscaling.

FPS and Codec Controls for Professional Output

Professional video delivery has specific technical requirements that go beyond resolution. Broadcast standards, platform specifications, and post-production workflows all have expectations around frame rate and codec.

LTX Studio's FPS controls within the Topaz upscale workflow let you match your output to these requirements during the upscale step rather than as a separate post-processing task. If your delivery requires a specific frame rate, setting it during upscale ensures the output is ready for your pipeline without additional conversion.

Codec selection follows the same principle. Choosing the right codec at the upscale stage means your output is formatted correctly for its destination, whether that is a social media platform, a broadcast delivery server, or a post-production suite like Premiere Pro or DaVinci Resolve.

Credit Cost and Processing Time

Topaz video upscaling consumes credits based on the resolution multiplier and output settings. Higher multipliers and higher-quality codec settings cost more credits per upscale. Processing time also scales with these settings: a 2x upscale processes faster than a 4x upscale of the same source.

For budget-conscious workflows, the practical approach is to upscale selectively. Not every generated clip needs maximum upscaling. Upscale your hero shots and key scenes at 4x with Topaz. Use Z-Image or lower multipliers for supporting footage that appears briefly or at smaller display sizes.

Best Practices for AI Video Upscaling

When to Upscale (and When Not To)

Upscale when your output needs to meet a specific resolution or quality standard that the generation model did not produce natively. This includes client deliverables, broadcast content, large-screen presentations, and any context where viewers will see the video at high resolution.

Do not upscale during iteration. When you are testing prompts, exploring creative directions, or building rough cuts, the native generation resolution is sufficient. Upscaling at this stage wastes credits and slows down your iteration cycle without meaningful benefit.

Combining Upscaling with Other Post-Processing

Upscaling works best as one of the final steps in your production pipeline. The recommended order is:

• Generate your video at native resolution

• Iterate on prompts and creative direction until you have a version you are satisfied with

• Assemble your sequence in the video editor

• Apply transitions, speed adjustments, and blending as needed

• Upscale the final clips or export-ready sequence with Topaz

• Export for delivery or handoff to external post-production

Upscaling before editing means you are working with larger files throughout the edit process, which can slow down your workflow. Upscaling after editing ensures you only process the footage that makes it into the final cut.

Upscaling for Different Output Formats

Different delivery destinations have different requirements. For social media video, 1080p is typically sufficient, and a 2x upscale from 720p achieves this efficiently. For broadcast or corporate video production, 4K is increasingly the standard, requiring a 4x upscale.

Match your upscale settings to your delivery target. Over-upscaling wastes credits and produces unnecessarily large files. Under-upscaling delivers footage that does not meet the platform or client requirements. The right approach is intentional: know your delivery resolution before you upscale, and configure accordingly.
