The best starting settings are conservative: choose the smallest output that meets your delivery target, preserve the source frame rate unless you have a deliberate interpolation or slow-motion goal, and stabilize only when camera shake is distracting enough to justify cropping. Identify whether the source is progressive or interlaced, preserve its aspect ratio, and preview a representative section before rendering the entire file. Compare the preview with the original at the intended playback size; larger dimensions, higher frame rates, or heavier stabilization do not automatically mean a better result.
The controls differ by application and model. The guidance below reflects documented workflows from Topaz Video, Adobe Firefly, and NVIDIA RTX Video, not an independent benchmark or a universal winning preset.

How do I choose AI upscaling settings before I process a video?
Start with the delivery requirement, then work backward to the source and the compromises you are willing to make. Resolution, frame rate, and stabilization solve different problems, so changing one should not automatically trigger changes to the others.
1. Decide where the finished video will be watched
A phone, a web player, a 1080p television, and a 4K display do not require the same output dimensions. Set the output to the smallest useful target for the destination. Upscaling beyond that target creates a larger file and more processing without establishing that the image contains more authentic detail.

2. Record the source properties
Check the source dimensions, aspect ratio, frame rate, and scan format. A progressive file contains complete frames; interlaced material stores fields and needs a deinterlacing-aware workflow. Also note whether the shot is intentionally handheld, locked off, panned, or already stabilized. Those observations determine which controls are worth changing.
3. Plan a short test
Choose a representative section containing faces, fine texture, edges, motion, and any difficult lighting. Process that section with the intended output dimensions and export settings. Review it beside the original before committing to a full render.

Choose the output dimensions from the delivery target, not from the largest number a menu offers. Topaz Video documents original-resolution, scale-multiplier, and custom-dimension controls; its August 2026 tutorial says a 2x scale takes 1080p to approximately 4K and recommends locking the aspect ratio when entering custom dimensions. Available sizes can depend on the selected model.
| Output choice | Use it when | Important qualification |
|---|---|---|
| Original resolution | The file already matches the destination dimensions or you want enhancement without resizing. | Enhancement can change clarity or texture while leaving the pixel dimensions unchanged. |
| 2x | You need a moderate size increase and the destination is roughly twice the source dimensions. | Topaz gives 1080p to approximately 4K as an example; the result depends on source footage and model. |
| 4x | A much larger delivery size is genuinely required and the model exposes that option. | A larger canvas does not prove that new detail is physically present in the source. |
| Custom dimensions | The delivery specification is exact or the source needs a nonstandard size. | Lock the aspect ratio to avoid geometric distortion; some models limit possible dimensions. |
Use a multiplier only when it matches the destination
Multipliers are convenient when the source and destination share a simple relationship. They are not quality grades. A 2x setting is not automatically better than a custom size that matches the display, and 4x is not a requirement for a 4K label if the source or model cannot support useful detail at that scale.
Understand the documented pixel example
Topaz’s February 6, 2026 tutorial illustrates 322×240 footage scaled 2x to 644×480. That is a product example showing how the arithmetic works, not a recommendation or a measured quality result for every low-resolution file. Treat it as a sizing illustration rather than a benchmark.
Keep the aspect ratio intact
Enter both dimensions only when the delivery specification requires them, and enable the application’s aspect-ratio lock where available. If a platform requires a different shape, decide separately whether to crop, add bars, or deliver a reformatted version; do not stretch the picture to fill the frame.

Should I convert the video to 60 FPS?
Keep the source frame rate for an ordinary upscale. Frame interpolation is a separate decision from increasing resolution and should be used only when the intended playback, delivery specification, or slow-motion effect calls for new frames.
| Goal | Frame-rate choice | What to inspect |
|---|---|---|
| Normal enhancement with the same look | Retain the source frame rate. | Motion cadence, cuts, and lip-sync should remain consistent with the original. |
| 60-FPS delivery | Use an interpolation workflow designed to change the frame rate. | Look for warped edges, duplicated objects, and uneven motion in busy scenes. |
| Slow motion | Use a slow-motion interpolation mode rather than treating every clip as a standard 60-FPS conversion. | Check fast movement and overlapping subjects, where synthetic frames are most conspicuous. |
| Interlaced legacy footage | Deinterlace first or use a combined deinterlacing-and-enhancement workflow. | Some deinterlacing workflows can double the output frame rate, so verify the exported file. |
Topaz lists an upscale-to-4K preset separately from a 60-FPS preset and distinguishes interpolation modes for slow motion. That separation is a useful mental model: a sharper, larger image does not inherently need more frames.
Why a higher frame rate can look worse
Interpolation invents intermediate frames. When the algorithm cannot reconcile an object’s movement, the result can show bending, trails, or an unnatural motion cadence. Preview a section with hands, hair, foliage, vehicles, and camera movement; those areas reveal interpolation errors more readily than a static talking head.
Will stabilization reduce resolution?
It can. Stabilization estimates camera movement and commonly crops or reframes the image so the subject stays within the visible area. Topaz explicitly says its Auto-Crop Stabilization preset reduces output resolution, so compare the steadier framing with the original before accepting the trade-off.
When stabilization is justified
- Use it when shake distracts from the subject or makes the footage uncomfortable to watch.
- Preview the entire frame, especially the edges, because cropping can remove signs, hands, or contextual objects.
- Confirm the effective output dimensions after cropping; the nominal export size may hide a smaller usable picture area.
When to leave stabilization off
- Locked-off shots generally do not need it.
- Intentional pans, tracking moves, and handheld documentary movement can lose their purpose if forcibly leveled.
- Do not enable stabilization merely because you are upscaling. It addresses camera motion, not missing detail.
Topaz’s user-interface documentation describes stabilization as a shake-reduction function, while its presets recommend Auto-Crop Stabilization for many stabilization needs. Those are product-specific controls; other applications may expose different crop or border behavior.
Which source type and enhancement strength should I use?
Match the processing path to the footage before adjusting intensity. Modern digital files are often progressive. Interlaced recordings need a workflow that removes the field structure before or as part of enhancement.

Progressive footage
For progressive video, start with the application’s automatic estimate or model recommendation, then judge the short preview. Topaz documents Auto, Dynamic relative to Auto, and Manual modes. Auto can provide a starting point; Dynamic relative to Auto lets you move away from that estimate; Manual gives direct control when you understand the artifacts in your source.
Interlaced footage
Identify interlacing before choosing an enhancement model. Topaz documents combined deinterlacing and enhancement for this material. Because deinterlacing can alter the output frame rate, inspect the file’s metadata and playback rather than assuming the original number remains unchanged.
The Tool Desk
Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Detail recovery and texture controls
Topaz describes Recover Detail as mixing original detail back into enhanced footage. That can help retain a natural relationship to the source, but too much original material can also preserve noise or softness. The Add Noise control can counter an overly smooth texture after denoising. Adjust these controls by appearance in the preview, not by copying a slider value from another clip.
“Please note, every piece of footage is unique and we encourage experimentation with different models and parameters as part of the creative process.”
No slider value is universally optimal. A clean digital source, a compressed web download, a film transfer, and an interlaced tape capture can require different models and strengths even when their pixel dimensions match.
What is a reliable step-by-step workflow?
Use this sequence for an offline upscale, then adjust only the decision that addresses the problem you actually see.
- Inspect the source. Record dimensions, aspect ratio, frame rate, scan format, and visible shake. Confirm whether the file is progressive or interlaced.
- Set the delivery dimensions. Choose original resolution, a sensible multiplier, or custom dimensions that meet the destination. Lock the aspect ratio and avoid scaling beyond the destination without a specific reason.
- Choose the source-appropriate enhancement path. Use a progressive workflow for progressive footage and a deinterlacing-capable workflow for interlaced footage. Start with automatic estimates when you do not yet know which model fits.
- Process a representative preview. Include faces, text or fine edges, texture, shadows, and motion. Compare the result at the intended viewing size with the original, not only at an extreme zoom.
- Keep the frame rate unless the goal requires a change. Add interpolation for a deliberate 60-FPS delivery or slow motion, and inspect difficult motion for synthetic-frame artifacts.
- Add stabilization only when shake is distracting. Compare the crop and edge composition, and check the effective picture area after stabilization.
- Export a short sample. Use the intended codec and quality settings, then play the file on the target device or software before starting the full render.
Which export settings should I check?
Export controls are application-specific, so verify them against the current version of the software. Topaz’s February 2026 tutorial identifies H.264 and H.265 as common codec choices and says its workflow requires H.265 for outputs above 4K. Treat that requirement as specific to the documented Topaz workflow, not as a universal rule for every editor or platform.
Check the exported file, not just the preview window
- Confirm the actual pixel dimensions and frame rate in the exported file.
- Watch for playback stutter that was not visible during processing.
- Check that audio remains synchronized after any frame-rate conversion or deinterlacing.
- Inspect the first and last frames for unintended cropping, black borders, or a changed aspect ratio.
A short export catches codec, compatibility, and timing problems before you spend hours rendering the complete source.
How should I compare different AI upscaling tools or workflows?
Compare them on the same representative clip, with identical output dimensions and comparable export quality. A result from one tool is not meaningful evidence against another if the source segment, crop, frame rate, or delivery size changes.
- Fidelity versus creative synthesis: Adobe describes Firefly’s Precise mode as preserving the source look more closely and Creative mode as adding detail. Decide which objective fits the footage.
- Resolution controls: Check whether the tool offers original, multiplier, and custom dimensions, and whether the chosen model restricts those options.
- Frame interpolation: Look for separate controls and modes for ordinary frame-rate conversion and slow motion.
- Stabilization behavior: Determine whether stabilization crops, scales, adds borders, or changes the effective output area.
- Processing location: Identify whether processing is local or cloud-based and whether the workflow requires supported hardware or an upload.
- Export controls: Verify codec, frame-rate, audio, and maximum-resolution limits before committing to a long render.
These are vendor-described capabilities, not independent performance findings. The available documentation does not establish one application, model, resolution, or frame rate as best for all footage.

What problems appear in previews, and how do I correct them?
The image looks too sharp or stylized
Adobe’s Firefly video-upscaler guidance tells users to review the result and adjust it if it looks too sharp or stylized. Reduce the enhancement strength or choose a mode oriented toward preserving the source look, then preview skin, text, and high-contrast edges again.
Fine texture has become plastic or smeared
Excessive denoising can smooth texture. Try a less aggressive model or adjust the detail controls; Topaz documents Add Noise as a way to counter texture smoothing after denoising. Use the original as the reference instead of adding grain simply because the enlarged image feels empty.

Motion contains warping or trails
First test the original frame rate. If the artifact appears only after conversion, disable interpolation or use a mode intended for the specific slow-motion or frame-rate goal. Recheck fast-moving subjects and overlapping objects.
The stabilized shot feels too tight
Compare the stabilized preview with the source edges. If the crop removes important context or lowers the effective resolution too far, leave stabilization off, reduce its strength if the application allows it, or accept the original movement.

Can an RTX graphics card improve playback without an offline render?
NVIDIA’s RTX Video Super Resolution is a real-time playback enhancement for GeForce RTX GPU owners, not a replacement for an offline editing upscale. NVIDIA recommends Auto quality, which adjusts to the system profile and source content; forcing a high fixed setting can cause stuttering on hardware that cannot sustain it. A GeForce RTX graphics card is therefore relevant when the goal is enhanced playback, while an editor-rendered file is still needed for distribution.
See the NVIDIA RTX Video FAQ for current compatibility details. No particular GPU model is established here as the best choice.
What do the current vendor guides actually establish?
The official guides document available controls and example workflows, not a universal quality ranking. Topaz’s resolution and enhancement documentation, its presets, and its February and August 2026 tutorials explain how to select dimensions, interpolation, stabilization, and source-type processing. Adobe documents review-and-adjust behavior and its Precise and Creative modes. NVIDIA documents Auto quality for RTX Video playback.
There is no named statistical study or broadly applicable performance figure supporting a single “best” setting. Use the documentation to configure a controlled preview, then make the final decision from your own source and delivery requirement.
What should my final checklist be?
- Delivery size chosen before enhancement.
- Aspect ratio locked and source type identified.
- Source frame rate retained unless interpolation has a defined purpose.
- Stabilization enabled only when shake outweighs crop and resolution loss.
- Representative preview checked against the original for detail, faces, edges, texture, and motion.
- Short export verified for dimensions, frame rate, audio sync, codec compatibility, and playback before the full render.
Frequently Asked Questions
Can AI upscaling recreate detail that was never captured?
It can synthesize plausible texture and edges, but increasing pixel dimensions does not prove that the added information was present in the source. Treat enlarged detail as a model-generated interpretation and check whether faces, text, and fine patterns still agree with the original.
Why does an interpolated 60-FPS file sometimes feel unnatural?
The extra frames are generated rather than recorded. When motion is ambiguous or objects overlap, the algorithm may bend shapes or create trails, producing a cadence that differs from the source; retaining the original frame rate avoids that change.
Does stabilization always crop from the center?
The exact framing behavior depends on the application and preset. Review the edges of the preview and the exported dimensions because a stabilizer may crop or reframe differently during the shot, even when the nominal output size remains unchanged.
