Why does exporting video from CapCut lose quality - what's the problem?

Usually it also helps to check which codec you're exporting in - if you've got H.264 selected, the quality can drop, but H.265 gives you a better picture at the same file size. I had a situation where I was making a video for Instagram, maxed out all the settings, and the result was still blurry - turned out the source material was in low resolution, and CapCut just can't pull quality out of something that isn't there. So also check what resolution you filmed your original footage in.

Quality doesn't drop just because of bitrate, which is what people usually recommend upping. I had videos coming out blurry even with max export settings - turns out the problem was with the source material. If you're shooting on your phone or using low-res video, CapCut can't make it any better than that. So first thing, check what quality you're working with in the editor itself - set your project to match your source video's resolution or higher (like 1080p if the original supports it).

Now about the export itself. Yeah, bitrate matters, but don't forget about frame resolution - sometimes CapCut exports at a different resolution than what you picked. Before exporting, check your settings for resolution and frame rate, make sure they match your project. Codec does have an effect, but honestly, the mobile version of CapCut has limited codec options, so that doesn't always help.

One more thing - CapCut sometimes compresses video on export to make the file smaller. If you can, export to cloud storage through the app itself; you'll get better quality that way than saving locally to your phone. And check if you've got something like a "save data" option or whatever in your general settings - it can automatically lower quality.

Actually, it's often not CapCut itself but how you prepare your source material. If your original video or images are already low quality, no export settings will save you. Before final editing, check the resolution of all media files in your project - everything should be at least as high as your final video resolution. And here's another tip: don't export directly to social media straight from CapCut. Instead, save a high-quality master file to your computer first, then format it for the platform afterward - that way you have more control over quality and less loss from intermediate compression.
