Video quality & audio formats

Resolution describes pixel dimensions, not overall picture quality. A 1080p source may look better than a heavily compressed 4K file. MP4 and WebM are containers; compatibility depends on the video and audio codecs inside. Some high-resolution sources contain no audio. These are clearly labelled. Audio-only files appear only when the source provides them. SaveClipo does not upscale or convert audio to a made-up MP3 option. File sizes appear only when known.
