A: Yep—downscaling from 4K to HD is super common, especially when you’re trying to save space or make uploads faster.
Q: Does converting reduce video quality?
A: Not always. It depends on the settings you choose. Stick to high bitrates and compatible formats, and you’ll be golden.

Q: What is video conversion, anyway?
A: Video conversion is simply changing a video file from one format to another—like turning an MOV into an MP4. It helps your videos play smoothly across different devices or apps.
Q: What’s the difference between MP4 and AVI?
