Viewing Tips & Contact us

Thanks to Samsung for the original SDR clips of the above at "4kmedia.org". These clips were automatically regraded from SDR/HD Rec709 originals to UHD 1200nits HLG, BT2020 color using isovideo Viarte systems.

For smooth viewing, please download a clip first. The HLG clips are best viewed on a 1200 nits HDR TV set to HLG and BT2020. Color is ideally set at 50, and contrast at 85 (between 75 to 95), depending on your TV. Adjust contrast to maintain detail and avoid saturation. For HDR TVs with less than a 1200 nits capability, some bright deltails may be lost. Note that any saturation in the source material cannot be removed during processing, and will appear in the converted results. If you have comments and suggestions, we would love to hear from you. If you have SDR footage and would like to get a regraded HLG version, or request a free trial, please do not hesitate to contact us. Thank you!
