SDR Ready

What does SDR Ready actually fix?

iPhone records HDR video (Dolby Vision, HLG, HDR10). On screens and apps that don't understand HDR — Windows PCs, Discord, many older TVs — that footage looks pale, flat, and gray. SDR Ready converts a copy to standard SDR (H.264, Rec.709) that looks right on every screen.

Does the conversion touch my originals?

Never. SDR Ready saves a converted copy to your Photos library, right next to the original. The original is not modified, moved, or deleted — and that behavior cannot be switched off.

Will the converted video lose quality?

Tone mapping can't invent detail that HDR highlights held, so the converted copy matches what the Photos app shows on an SDR screen — not the extra brightness your iPhone display adds. In practice it looks like what you saw when you shot it.

Which videos can it convert?

Anything your iPhone records: Dolby Vision, HLG, and HDR10 clips at any resolution. Videos that are already SDR are detected at pick time and marked "already fine" — the app refuses to run pointless conversions.

Does it need the internet?

No. Conversion runs entirely on your iPhone using Apple's own video framework. The app works in airplane mode.

A clip failed to convert — what now?

Some screen recordings and third-party-app videos use unusual color formats. Tap "Report this clip" on the results screen (or email directly) and include what app recorded the clip — the format details help fix support for it. The video itself is never sent.
