AI video upscaling uses machine learning to increase video resolution — turning 480p into 1080p, or 1080p into 4K — by intelligently predicting and adding detail that wasn’t in the original footage, rather than just stretching existing pixels.
The old way of upscaling was blurry and obvious. AI upscaling in 2026 is genuinely impressive. Here’s how to do it properly.
What Is AI Video Upscaling?
AI video upscaling is the process of using neural network models to increase video resolution by intelligently reconstructing and adding fine detail — textures, edges, sharpness — rather than simply interpolating pixels like traditional bicubic upscaling does.
Traditional upscaling stretches pixels mathematically. The result looks soft and blurry because no new detail is added. AI upscaling is different — models trained on millions of video frames learn what real-world detail looks like and reconstruct it from lower-resolution input.
The practical result: a 720p interview clip can look convincingly close to 1080p. A 1080p clip can pass as 4K on most screens. The limits depend on source footage quality, but the improvement is usually dramatic.
In 2026, AI upscaling is used by YouTubers reviving old content, editors delivering 4K projects from mixed-resolution footage, and archivists restoring historical video.
Why AI Upscaling Matters in 2026
AI video upscaling in 2026 allows creators to deliver 4K-quality content from lower-resolution source material — critical for monetizing older footage libraries, meeting client delivery specs, and future-proofing content for larger screen formats.
- Revive old content: YouTube videos shot in 1080p 5 years ago can be re-exported in 4K and re-uploaded with new SEO.
- Meet client specs: Many corporate and broadcast clients now require 4K delivery. AI upscaling bridges the gap when source footage doesn’t meet that standard.
- Future-proof your library: 4K and 8K screens are more common every year. Upscaling your library now means less re-shooting later.
- Save money on reshoots: Unusable low-res footage can often be salvaged with upscaling instead of expensive reshoots.
Best AI Video Upscaling Tools in 2026
1. Topaz Video AI — Best Quality
The gold standard for local AI video upscaling. Multiple AI models optimized for different footage types. One-time purchase (~$299). Processes locally — no internet needed, no per-clip fees. Best-in-class results on talking-head and cinematic footage.
2. DaVinci Resolve (Super Scale) — Best Free Option
DaVinci Resolve’s Super Scale feature is AI-powered upscaling built directly into the color page. It’s free with DaVinci Resolve’s free version and handles standard upscaling well. Not as precise as Topaz on complex footage, but completely free and integrated into a full editing workflow.
3. Adobe Premiere Pro (AI Upscaling) — Best for Premiere Users
Adobe has integrated AI upscaling into Premiere Pro’s export workflow. If you’re already working in Premiere, you can upscale during export without leaving the application. Quality is good, though not quite at Topaz level.
4. Aiseesoft Video Enhancer — Best Budget Option
A lower-cost alternative (~$35 one-time) that handles basic upscaling well. Not as powerful as Topaz but good for occasional use without the premium price.
5. RunwayML (Video Upscale) — Best Cloud Option
RunwayML offers cloud-based video upscaling that works in-browser — no GPU required on your machine. Great for creators without powerful hardware. Credit-based pricing means cost scales with usage.

How to Upscale Video with AI — Step by Step
This walkthrough uses Topaz Video AI, the highest-quality option available in 2026. The general principles apply to other tools.
Step 1: Install Topaz Video AI and download the AI models.
Download from topazlabs.com → install → open the app → let it download the latest AI models (this takes a few minutes on first launch). You’ll need the “Upscale” model pack.
Step 2: Import your video.
Drag and drop your video file into Topaz Video AI. Most formats are supported: MP4, MOV, MKV, AVI. You’ll see the source resolution in the top left of the preview.
Step 3: Choose your output resolution.
Select your target resolution: 1080p, 4K, or custom. For most use cases, upscaling by 2x (e.g., 1080p → 4K) gives better results than 4x upscaling (480p → 4K) in one pass.
Step 4: Select the right AI model.
- Iris (Face Recovery): Best for talking-head, interview, and any footage with close-up faces.
- Apollo: Best general-purpose model for mixed content.
- Proteus: Best for detailed textures — landscape, architectural, product footage.
- Dione: Best for interlaced footage from TV recordings or older cameras.
Step 5: Run a preview before full processing.
Click “Preview” on a 5-second section of your clip. Review the quality before committing to a full export. Adjust the AI model or settings if needed.
Step 6: Export.
Click “Export” → choose your output format (MP4, MOV, ProRes) → set bitrate → start processing. Processing time: roughly 5–20 minutes per minute of source video, depending on your GPU.
Pro Tip: Process noise removal first, then upscale in a second pass. Upscaling after noise removal gives cleaner results than trying to do both simultaneously on noisy footage.

Common Mistakes to Avoid
- Upscaling already-compressed footage without noise removal. Compression artifacts get worse when upscaled. Always run noise reduction before upscaling on any footage that’s been compressed heavily.
- Choosing the wrong AI model. Iris for faces, Apollo for general content, Proteus for textures, Dione for interlaced. Using Apollo on interlaced footage produces visible combing artifacts.
- Skipping the preview step. Full exports on long clips take significant time. A 2-minute preview save costs nothing; fixing a wrong-model export costs 40+ minutes.
- Expecting identical results on all footage types. AI upscaling works exceptionally well on clean footage with good contrast. Heavily compressed, very dark, or motion-blurred footage has less information to work with and produces less dramatic improvements.
- Not exporting to the right format. If you’re taking Topaz output back into Premiere or DaVinci for further editing, export as ProRes or DNxHR, not compressed MP4. Re-compressing edited content twice degrades quality.
FAQs
Q: Can AI really upscale video to 4K quality?
A: AI upscaling in 2026 can make 1080p footage look very close to native 4K on most screens. It’s not identical to actually shooting in 4K, but the difference is minor for most viewing contexts. Results are most impressive on clean, well-lit source footage.
Q: What is the best free AI video upscaler in 2026?
A: DaVinci Resolve’s Super Scale feature is the best free AI video upscaling option. It’s built into the free version of DaVinci Resolve and handles standard upscaling well. For more advanced results, Topaz Video AI’s free trial lets you test before purchasing.
Q: How long does AI video upscaling take?
A: Processing time depends on your hardware, source resolution, target resolution, and clip length. With a modern GPU (RTX 3060+), expect 5–15 minutes per minute of video for 1080p → 4K upscaling in Topaz Video AI.
Q: Does AI upscaling work on old VHS or tape footage?
A: Yes, and it’s one of the best use cases. Topaz Video AI’s “Dione” model is specifically designed for interlaced and tape-sourced footage. Results on digitized VHS footage are often dramatically better than the original.
Q: Is it legal to upscale and re-upload old YouTube videos?
A: If it’s your own content, yes. Upscaling your own videos and re-uploading in higher quality is completely fine on YouTube. If it’s someone else’s content, the same copyright rules apply as any other re-upload — you need permission.
Wrap-Up
AI video upscaling in 2026 is one of the most practical AI tools available to creators and editors. Whether you’re restoring old footage, meeting client delivery specs, or future-proofing your content library — the quality improvement is real and the tools are accessible.
