対応フォーマットと画質
| MP4 / 4K (2160p) | VP9/AV1 source | saved without re-encode |
| MP4 / 8K (4320p) | where uploaded | large files — check disk space |
| MP4 / 1080p–1440p | H.264/VP9 | when 4K isn't offered |
Why most tools fail at 4K
YouTube serves 4K in VP9/AV1 with separate audio, which many web converters can't merge — so they silently give you 1080p or lock UHD behind a paid tier. ClapClip fetches the true UHD stream, muxes the audio locally, and saves real 2160p, free.
4K matters when the footage works for a living
Editors cropping and reframing, colorists grading, anyone producing for a 4K timeline — starting from 1080p means upscaling later. Downloading the native UHD keeps every pixel the uploader provided. And for older 1080p sources, ClapClip's AI video upscaler can bring footage up to 4K afterwards.
Big files, planned for
An hour of 4K can exceed 10 GB. ClapClip shows estimated sizes before download, saves to whatever drive you pick, and resumes interrupted UHD downloads instead of restarting them — the practical details that make 4K workable.
Honest resolution, always
If a video was uploaded in 1080p, no downloader can produce genuine 4K from it. ClapClip lists only real available streams — and where you need more resolution than the source offers, the built-in AI upscaler is the honest tool for that job.
Free 4K desktop download vs paid 'HD tiers'
The most common web-tool trick: free at 720p, pay for 1080p, subscribe for 4K. Local downloading has no bandwidth bill, so there is nothing to tier. Full resolution — including 8K — is simply included.
よくある質問
Is it really 4K, not upscaled?
Yes — ClapClip downloads the original 2160p stream. File properties will show true 3840×2160 at source bitrate.
Does 8K work?
Yes, for videos uploaded in 8K (4320p). Expect very large files.
Why do some videos only offer 1080p?
Resolution depends on the upload. ClapClip lists what genuinely exists; it never fakes UHD.
Can I batch-download a playlist in 4K?
Yes — set 2160p once and the whole queue downloads at maximum available quality.
Is 4K downloading free?
Yes. No resolution tiers — 4K and 8K are included.
