HDR to SDR Tone Map converts HDR phone captures to SDR so YouTube, TikTok, and Meta players do not wash out contrast when they re-encode your owned clip.
Why tone-map HDR before social upload?
Tone-map HDR before social upload because many web and app players assume SDR; unmapped HDR often looks flat or washed after platform re-encode.
What does tone-mapping HDR phone video change before social remux?
HDR to SDR produces SDR delivery so web and social players do not wash out HDR phone video.
What this pass delivers for HDR→SDR for web and app players:
- HDR phone captures tone-map to SDR before YouTube, TikTok, or Meta re-encode.
- Contrast and skin tones stay closer to what appeared on device.
- Later uploads look consistent instead of flat on one app and fine on another.
What do washed SDR players do to unmapped HDR uploads?
Without tone-map, HDR uploads face washed-out HDR uploads that look broken after platform remux.
What milky contrast does to the open after remux:
- Unmapped HDR often looks milky or low-contrast after social re-encode.
- Viewers bounce when the image looks wrong in the first seconds.
- Posts burn on debugging “why this looks different on phone vs the feed.”
How does a feed-readable SDR image relate to early watch?
An SDR deliverable is a feed-readable SDR image platforms score for watch time.
How most social pipelines treat HDR sources as SDR:
- Most social players assume SDR; HDR mismatches are a common silent quality killer.
- A washed open loses viewers instantly — and with them, recommendation momentum.
- Tone-mapping before upload matches creators who already ship SDR deliverables.
- Without the map, washout surfaces only after the post is live.
Tone-mapping produces an SDR deliverable for SDR-first social players; platforms still re-encode after upload.
How does HDR to SDR tone mapping work in this tool?
HDR to SDR tone mapping reads HDR transfer metadata (e.g. HLG/PQ), compresses highlight range into an SDR gamut, and re-encodes an SDR H.264 deliverable for social ingest.
Pipeline stages:
- Detect HDR color transfer from stream metadata.
- Apply tone map from HDR luminance into SDR range.
- Encode SDR output suitable for Shorts, TikTok, and Meta players.
Do creators probe with technical analysis before HDR to SDR?
Technical analysis runs when HDR status is unknown; HDR to SDR runs when the probe (or phone export label) already shows HDR transfer that social players mishandle.
When do creators skip HDR to SDR tone mapping?
Creators skip tone mapping when the master is already SDR, or when an HDR master remains required for a platform and display path that preserve HDR end to end.
HDR to SDR tone map for social converts HDR phone captures to SDR H.264 so app players keep contrast on owned clips.
