Bonjour,

La prise en compte de HDR est annoncée pour dans deux semaines environ, voir le message de Jim Peterson ci-après, source : http://www.convergent-av.co.uk/forum/in ... #msg_22765

I am pleased to announce that we are close to the initial HDR release. We should be posting the HDR release in approximately two weeks. Before all we had was a guesstimate. However, we now have HDR working through the Radiance Pro from a Samsung UHD player to a Sony HDR TV including accepting and outputting HDR Info Frames. This is a major milestone, and we are estimating it will be about two weeks until we have this in the software in an update.

Pro owners with the Panasonic UHD player, or a Kaleidescape Strato (if you have access to the HDR demo movie which I believe is only available to Kaleidescape dealers at this time) will be able to use HDR once the HDR release is posted.

As some of you have already surmised, this means we have the 18 GHz input card prototype working in the lab. We are revising the 18 GHz input card and expect to have initial production boards to sell at the end of August if all goes well. This will allow Samsung UHD player owners to view HDR material through the Pro.

============================

A Radiance Pro implementation detail is that the first HDR releases will focus on driving HDR TVs and projectors.

Later we focus more on reporting HDR to sources when using a non-HDR TV/projector and calibrate them to do their best for Rec 2020 color Gamut and brighter highlights than Rec 709 is capable of. This is actually going to be in the early HDR software, but we will need to add more details and work with calibration software companies to make this practical.

================================

Please note that the calibration software programs do not yet work correctly using the Radiance Pro in Rec 2020 (or HDR) 3D LUT mode. We are working with them to add the necessary support.

Contact sales@lumagen.com for more information about upgrading RadiancePro input cards from 9Ghz to 18Ghz. Added support for HDR. The CMS selected for HDR is the same CMS used for Rec2020 (see menu under Output: Output Setup). If needed you can disable HDR from all sources in the menu under Global: Video: Src Format: HDR. Samsung UBD-K8500 now working with 4k24 HDR-Rec2020 444 output to the RadiancePro with new 18Ghz card. Added deep color support. Numerous RS232 changes and additions for HDR/Rec2020 support---updated commands include ZY530, ZY533. New commands: ZQI22, ZQI51, ZY540-ZY547 (see updated TechTip11 rev072516 for details). Bugfix for input top mask with 4k source. Bugfix for setting LBox Zoom to 'Off'. Eliminated momentary screen blank when reselecting input aspect. Fixed issue with interlaced input vertical masking and shift settings not using same value as progressive. Fixed issue with output triggers being incorrectly triggered.

Bonjour à tous

Je souhaitais avoir votre avis sur le HDfury Linker vs le Radiance pro
J'imagine que vu l'écart de prix, le radiance et le linker n'ont pas la même fonction ?
Pour quelqu'un comme moi qui passera a moyen terme sur un projo HDR (Sony 550) et lecteur Oppo UHD, le linker peut il être une solution moins chère que le radiance mais quand même qualitative ?
Merci et bon dimanche

Bonjour,

Nous y sommes presque :

Beta 101416- Added to NLS setup screen to allow for 100% linear stretch--NLS setup is under Input: In Configs: RES: CFG: Size: ASPECT: NLStretch. Center Size controls linear portion and has range from 15-75% or 100%. Improved color bandwidth for RGB sources. Several improvements for switching inputs with new 18Ghz input cards. Added manual override for 422, 444 or RGB input type in menu under Input:Options:HDMI Setup:Type . Added global 709 CMS Mode in menu under Global: VIdeo with settings of Source or Linear. Linear-Gamma mode is used in older Radiance models. For the Radiance Pro Source-Gamma is used for Rec2020/HDR currently and is now an option for Rec709 3D LUT calibration. Check with your calibration software vendor for software updates if you plan to use Source-709 Gamma mode. Please continue giving us your detailed feedback on issues via email at radiancepro_beta@lumagen.com . Update time ~1 minute @230k from previous firmware


La partie soulignée en gras est très importante pour la calibration. Je n'ai pas testé car je ne possède de Radiance PRO mais je pense que c'est l'option qui permet de faire le tone mapping pour gérer le HDR correctement qu'on utilise un diffuseur HDR ou SDR seulement.
