The SD card mistake that ruins your video

By the Skint Kit crew · How we pick

Here's a mistake that ruins good footage: using any old SD card for video. Cheap, slow cards can drop frames, stop recording halfway, or refuse to shoot four K at all.

The speed that matters for video is the sustained write speed, not the big number printed on the front. Look for a V30 rating for four K, or V60 and V90 if your camera records high bitrate formats.

Check your camera's manual for what it asks for. And buy from a reputable seller, because fake cards are common on marketplaces.

A good card costs a few pounds more than a bad one, and it can save a shoot you can't repeat. Links below are affiliate links.

FAQ

Is a used lens worth it?

Usually yes. Lenses hold their value and rarely wear out, so a used one from a reputable seller with a returns policy often gives far better glass per pound than a new budget lens. Check for fungus, haze, scratches and smooth focus and zoom rings before you buy.

What is the best budget lens?

For most people a used 50mm f/1.8 for your camera system is the cheapest big upgrade over a kit lens: sharp, light and great in low light. Check the picks on this page for specific options.

Do presets work on a phone?

Yes. Lightroom presets work in the free Lightroom mobile app on iPhone and Android: import the DNG preset files, then apply them to your photos with one tap.
