Questions and answers
Everything about how SDR to HDR works, what we do with your videos, and how billing happens.
What is the difference between SDR and HDR?+
SDR (Standard Dynamic Range) video is mastered for roughly 100 nits of brightness and 8-bit color. HDR (High Dynamic Range) carries far more brightness headroom and 10-bit color, so highlights sparkle and gradients stay smooth on HDR screens.
What exactly do I get back?+
A 10-bit H.265 HDR10 MP4 file. Resolution and frame rate are preserved from your source — a 1080p30 clip comes back as 1080p30, a 4K60 clip as 4K60.
What can I upload?+
MP4, MOV, or WebM files up to 60 seconds and 500MB. Longer clips are coming — for now, trim to the moment that matters.
How much does it cost?+
$6.00 per 10 seconds at 1080p and below, $12.75 per 10 seconds above 1080p (4K). Minimum charge is $0.60 per conversion. HDR-50 and HDR-200 plans cut that by 8% and 20% respectively.
Do I need a subscription?+
No. Top up any amount from $50 and convert at the standard rate. Subscriptions (HDR-20, HDR-50, HDR-200) exist only to lower your per-second rate if you convert regularly.
What happens if a conversion fails?+
You are refunded automatically — the full charge lands back in your balance within minutes, and we email you. Stuck jobs are force-refunded by our cleanup job.
Where will the HDR video play?+
Any HDR10-capable screen: modern HDR TVs, iPhone 12 and later, iPad Pro, MacBook Pro with XDR displays, and YouTube (which detects and serves the HDR10 stream automatically).
Is my video private?+
Yes. Uploads live in a private bucket, are served over short-lived signed URLs, and are auto-deleted after 7 days. We never train on your content.
Does conversion change resolution or frame rate?+
No. The AI engine remaps luminance and color only — every frame of your source is preserved at its native resolution and cadence.
Does my balance expire?+
Top-off balances never expire. Subscription balances refresh each billing cycle and reset to the plan amount on renewal. Cancel anytime.
