FAQ
Can AI really improve blurry video? Yes — noticeably. Old low-res videos become watchable/sharp on modern screens. It's not magic but it's real improvement.
Best free option? CapCut for ease; Video2X for quality if you can set it up.
How long does it take? Upscaling is slow — a 5-min video can take 30min-2hrs depending on quality settings and your PC.
Bottom Line
Start with CapCut's free enhance — it handles most cases. For serious restoration (old family archives, professional work), Topaz Video AI is worth the investment.
