By the end of this guide you will have taken a low-resolution or soft video and produced a larger, sharper version, for example 1080p or 4K, and checked it against the original so you know the result is worth keeping. An AI video upscaler does the job: it analyses the footage, adds pixels and plausible detail, and can also smooth motion or convert dynamic range.
The right AI video upscaler depends on whether you want strict fidelity to your source or a more creative rebuild, and whether you render on your own computer or in the cloud. This guide walks through the steps and compares four tools from our Video category. Coverage in our directory for this task is narrower than for most topics, so the comparison is short.
Key takeaways
- Test a short clip first, compare it with the original side by side, and only then process the whole video.
- The main decision is fidelity versus creativity, and local versus cloud rendering. Topaz Video lists both a Precision Upscale and a Creative Upscale model, and renders locally or in the cloud.
- Cloud tools meter by credits or tokens, so long clips can cost more than you expect. Check the cost before you render.
- Upscaling cannot recover detail that isn't in the footage. Do not use generative upscaling on material where accuracy matters, such as evidence.
What you need before you start
- Your highest-quality source file. Use the original export or the highest-quality copy, not a compressed re-upload.
- A short test clip. A few seconds from a difficult part of the video, with faces, text or fast motion.
- An account or install. Cloud tools need a sign-up. Desktop software needs an install.
- Storage and patience. Upscaled files are large and can take a long time to render.
- A target. Know the resolution and frame rate you need, for example 1080p or 4K.
- Time. A test and decision take under an hour. A full render can take much longer.
- Difficulty. Easy to moderate. The settings are simple, but judging quality takes a careful eye.
- Rights. Only enhance footage you own or have permission to adapt.
Which kind of AI tool fits this job
A dedicated video enhancement tool. Topaz Video is video enhancement software from Topaz Labs. Its listed workflows are Precision Upscale, Creative Upscale, Frame Interpolation, Slow Motion and SDR to HDR conversion. You can render locally as part of a desktop subscription, or in the browser through Topaz for Web, where video renders use monthly cloud credits.
A creative studio with video upscaling. Lupa is a browser-based studio that generates, edits and enhances images and video, and lists video upscaling to 1080p and 4K. It prices actions in tokens, with a per-model cost table. Popcraft brings video, image, audio and avatar generation under one credit balance and lists upscaling footage to 4K.
A broader creative platform that includes upscalers. Magnific puts generation next to editing and upscaling tools, and its listing mentions Magnific and Topaz image and video upscalers. It suits people who already use it for images and want video upscaling in the same place.
Step 1: Define what you want to improve
Different problems need different fixes, so name yours before choosing settings.
- Write down the goal: higher resolution, smoother motion, slow motion, or a dynamic-range conversion.
- Note the source's resolution, frame rate and condition (grainy, compressed, blurry).
- Decide how faithful the result must be. Family footage and archive material often call for faithful results. Stylised content can tolerate a more creative rebuild.
- Set the target resolution, for example 1080p or 4K.
Check it worked by writing the goal in one sentence, such as "upscale the old interview to 4K, keep faces natural".
Step 2: Prepare a test clip
A test clip saves you hours and credits.
- Trim five to ten seconds from the hardest part of the video, such as faces, text on screen or fast movement.
- Keep the original file untouched.
- Export the test clip at the highest quality you have, without extra compression.
- Make a note of its length, because credit cost scales with length.
Check it worked by playing the test clip and confirming it shows the problems you want to fix.
Step 3: Choose a tool and check the cost
You end this step with a tool picked and a cost estimate for the whole job.
- Pick between local and cloud. Topaz Video's desktop subscription lists unlimited local rendering, while cloud renders use monthly credits that expire at the end of each month.
- Use the cost shown before rendering. Topaz Video shows the credit cost before you hit Render, and its docs give one example: Starlight Precise 2.6 costs 5 credits to reach 1080p and 20 credits for 4K on a 10-second clip at 30 FPS.
- Check plan limits. Lupa lists several video and enhancer options as unavailable on its Try plan, and Popcraft's free plan has 100 credits, one job at a time and 720p output up to 5 seconds.
- Compare the options in the table below.
Check it worked by multiplying the test clip's cost by the number of clips in the full video.
Step 4: Run the test and pick a model
Process the test clip with the setting closest to your goal.
- Upload or open the test clip in your chosen tool.
- Choose the target resolution. Lupa lists video upscaling to 1080p and 4K, and Popcraft lists upscaling to 4K.
- Choose the mode. Topaz Video lists separate Precision Upscale and Creative Upscale models, so test both if fidelity matters.
- Render the test, and try a second mode if the first disappoints.
Check it worked by seeing a finished test clip at the new resolution.
Step 5: Compare against the original
Judge the result carefully before you commit.
- Play the original and the upscaled clip side by side at full screen.
- Look closely at faces, text, fine textures and edges. Generative modes can invent details, such as altered facial features or smeared lettering.
- Watch for flicker, banding or a plastic, over-smoothed look.
- Test on the screen where the video will be shown, not just a laptop.
Check it worked by asking a second person which version looks more natural.
Step 6: Process the full video
Once the test looks right, process everything with the same settings.
- Make sure you have enough credits or time. Topaz Video offers one-time credit packs that never expire, and monthly cloud credits do not roll over.
- Render the full video, or the segments in batches if the tool limits job length.
- If you also want smoother motion, apply Frame Interpolation or Slow Motion where the tool offers them, such as Topaz Video.
- Keep the settings you used for each segment so you can match them later.
Check it worked by scrubbing through the full output at several points, including the start and the end.
Step 7: Export, label and archive
Finish with the file you will use, and keep the original.
- Export in a widely supported format and the resolution your plan allows.
- Re-check audio sync after export.
- If the footage is archival, journalistic or evidential, note that it was AI enhanced, because upscaled detail is generated rather than recorded.
- Keep the original next to the enhanced version.
Check it worked by playing the final file on the device where it will be viewed.

Common mistakes to avoid
- Expecting miracles from a poor source. Upscaling adds plausible detail, not true detail. Fix it by starting from your highest-quality copy and setting realistic expectations.
- Skipping the test clip. A full render in the wrong mode wastes time and credits. Fix it by testing a short, difficult segment first.
- Trusting generative detail on faces and text. Creative modes can alter features or lettering. Fix it by comparing against the original, and avoid them for material where accuracy matters.
- Ignoring credit costs. Cloud costs scale with length and resolution, and monthly credits may expire. Fix it by checking the cost before rendering and planning the job inside one billing cycle.
- Overwriting the original. A bad result is hard to undo without the source. Fix it by always keeping the untouched file.

Frequently asked questions
Can I upscale a video to 4K for free?
Only in a limited way. Popcraft's free plan gives 100 credits to try, but outputs are 720p, up to 5 seconds and watermarked. Magnific has a Free plan with limited daily use. For full-length 4K work you will probably need a paid plan or credits.
Does AI upscaling really add detail?
It adds plausible detail based on what the model has learned, not information that was in the original. Results can look convincing and still be wrong in small ways, especially on faces and text. Treat the output as an enhanced copy, not a faithful record.
Can I do it on my own computer instead of the cloud?
Topaz Video lists unlimited local rendering as part of its desktop subscription, as well as cloud rendering through Topaz for Web. Lupa and Popcraft are described as web apps. Magnific lists a desktop app, but its listing does not say whether video upscaling runs locally, so check its site.
Can AI make a video smoother or slower too?
Topaz Video lists Frame Interpolation and Slow Motion, which generate extra frames to raise frame rate or slow clips down. It also lists SDR to HDR conversion. Check the results for artifacts around fast-moving objects.
How long does it take to upscale a video?
The tools don't publish a standard time. Rendering depends on length, resolution, mode and your hardware or plan, so run a short test and extrapolate. As a rough editorial estimate, a decision on settings fits in under an hour, but a long video can take much longer to render.
