Turn Your Old Videos Into Sharp 4K with Topaz Video AI

Before we start, we need to make sure we're giving the AI the best possible version of your video. If you've got an old DVD or a file from years ago, run it through a free app called **Handbrake** first. We want to turn it into a high-quality MP4 or MKV file. If you see weird jagged lines in the video (that’s called interlacing), make sure to turn on the de-interlacing filter in Handbrake. It’s like cleaning a dusty window before you try to look through it.

Now, open **Topaz Video AI** and drag your video right into the middle. On the right side, you’ll see a panel called 'AI Models.' This is where you pick the 'brain' that will fix your video. For most old videos, pick **Proteus**. It gives you sliders so you can manually tell the AI what to fix. If the video is really messy or grainy, you can try **Artemis** instead—it's more of an 'automatic' mode. Finally, make sure to set your output size to **4K (3840x2160)**.

Since we're using **Proteus**, we can now play with the sliders. Your goal is to make things like hair or fabric look sharp again. Try moving the **Recover Details** slider up slowly. If the video looks a bit 'glowy' or has fuzzy outlines, use the **Dehalo** slider to clean that up. If the video starts looking too much like a cartoon or too smooth, you can actually add a little bit of 'Grain' back in. It sounds funny, but a tiny bit of texture makes the video feel more like a real movie.

Old videos can sometimes look a bit jittery. We can fix this with 'Frame Interpolation.' This is just a fancy way of saying the AI will create brand-new frames to fill in the gaps. Look for the **Apollo** or **Chronos** models in the settings. If you choose to double the frames (like going to 60fps), the movement will look incredibly fluid. It’s that 'smooth' look you see on modern TVs. If you want to keep the old-school movie feel, it's totally okay to skip this step!

We're almost there! Click export and pick **ProRes 422 HQ** as your file type. This file will be very big, but it ensures you don't lose any of that new 4K quality. Once the app finishes, your video might still look a little faded. You can bring the file into a tool like **DaVinci Resolve** to brighten the colors. Just a quick boost to the contrast (making the blacks darker and the whites brighter) will make all that new AI detail really stand out.
