Just over a week ago I was in Cape Town with a few hours to spare before my flight home and access to a Sony Venice. So what could I do other than go out and shoot. Here is some of the footage with a quick grade applied – in HDR.
The workflow: I shoot X-OCN ST at 25p and 50p on the Venice camera. 25p was requested by Visual Impact South Africa, the owners of this camera as this is the most common frame rate used in productions they are involved with. The material was backed up to a small portable USB3 raid unit so I could bring it home. Then it was graded using DaVinci Resolve and it’s ACES colour managed workflow with the output set to Rec2100 ST2084. I used a Shogun Inferno and both an LCD HDR Sony Bravia TV and an OLED HDR Philips TV to get a feel for how the images would look on both LCD and OLED technologies.
The file was exported as a UHD ProRes file so that the file direct from Resolve could be uploaded to YouTube. Because I used a colour managed workflow Resolve adds the correct HDR flags to the clip when you render the timeline out. As a result YouTube knows the file is HDR and if you view with a computer or SDR TV YouTube applies it’s default HDR10 to Rec709 LUT and you see the video in SDR. Watch with a direct connection to YouTube with an HDR TV (for example using a browser or YouTube player built in to the TV) and you will get the HDR version. This is probably the simplest way to reliably get HDR clips to play properly on YouTube (which currently does not accept HEVC files).
So here’s the clip.
IMPORTANT: The clip is HDR10, designed to be watched directly on an HDR TV using the TV’s built in web browser or YouTube player application.
Those watching on a normal computer, SDR TV or any other non HDR device will see the HDR clip with YouTube’s SDR/Rec709 LUT applied, so it isn’t exactly optimum for SDR. The YouTube HDR to SDR LUT causes some slightly odd colours in some of the clips. If you can, watch the clip directly on YouTube with an HDR TV.
Sony’s Pro Tour is visiting Oslo, Norway on the 8th of March 2018. At this event there will be the opportunity to see some of Sony latest video production kit including cameras from the handheld range like the PXW-FS7M2, PXW-FS5, PXW-Z90 as well as a large range of monitors, vision mixers and related video production technology.
There will be 4 different product areas as follows:
Large Format Sensor
Showing PXW-FS7 II, FS7 & FS5
4K HDR Production
Showing PXW-Z90, PXW-Z150 & HXR-NX80 (TBC)
Showing PXW-X70, PXW-X200, HXR-NX100
Live Event Production
Showing MCX-500, RM-30BP, HXR-NX5R, SRG-360, RM-IP10 and an RX0
As well as the exhibits there will be a seminar “HDR for all” from Alister Chapman with some great information on what HDR is, what you can expect from it and how you can use Sony’s cameras to create instant HDR content.
Admission is free. For more information and to register please CLICK HERE.
Just a very quick note that the last UK event of the Sony Pro Tour for 2017 will be in Glasgow on Thursday the 7th of December. I’ll be there to answer any questions and to give an in depth seminar on HDR including how to shoot HDR directly with the Sony cameras that feature Hybrid Log Gamma.
The event is free, there will be a wide range of cameras for you to play with including FS5, FS7, the new Z90 and X80 as well as monitors, mixers and audio gear.

Sony have just released firmware version 4.02 for the PXW-FS5. This firmware fixes the bugs found by Sony in the initial release of the version 4 firmware and includes the new Hybrid Log Gamma picture profile No. 10 along with a change to the cameras base ISO rating. I note that there is no mention of the problems with HLG clips in Adobe Premiere, so this will require further testing to see if this has been fixed.
Ver4.02 (Functionally, it is the same as the Ver.4.00.)
V4.02 fixes the following issue:
1. Video image may be recorded with short delay of 2 or 3 frames of audio in other recording modes than AVCHD.
2. When choosing [HLG1],[HLG2] or [HLG3] in the PictureProfile and CENTER SCAN in the CAMERA/PAINT menu, rebooting the camera may cause brightness and color shift.
Ver4.00(For your information)
1. Support for High Dynamic Range (HDR) by shooting in Hybrid Log-Gamma** (HLG) standard
2. Support for continuous 120fps High Frame Rate (HFR) recording in 1080p with CBKZ-FS5HFR (sold separately)
3. Option to change the minimum ISO sensitivity number to ISO 2000 from ISO 3200 when recording S-Log2/S-Log3
Sony will be releasing an update for the firmware in the Sony PXW-FS5 in the next few days. This update amongst other things will allow users of the FS5 to shoot to HDR directly using the Hybrid Log Gamma HDR gamma curve and Rec2020 color. By doing this you eliminate the need to grade your footage and could plug the camera directly in to a compatible HDR TV (the TV must support HLG) and see an HDR image directly on the screen.
But what about FS7 and F5/F55 owners? Well, for most HDR productions I still believe the best workflow is to shoot in S-Log3 and then to grade the footage to HDR. However there may be times when you need that direct HDR output. So for the FS7, F5 and F55 I have created a set of Hybrid Log Gamma LUT’s that you can use to bake in HLG and Rec2020 while you shoot. This gives you the same capabilities as the FS5 (with the exception of the ability to add HLG metadata to the HDMI).
For a video explanation of the process please follow the link to my new Patreon page where you will find the video and the downloadable LUT’s.
The PXW-FS5 and PXW-Z150 will both get a free firmware update some time around June that will add the ability to shoot using a special gamma curve called “Hybrid Log Gamma” or HLG.
In the case of the FS5 this will be added through an additional picture profile, PP10. As well as HLG the camera will also have the ability to record using Rec2020 color. As a result the camera will become compatible with the new Rec2100 standard for HDR television.
In addition the FS5 will get the ability to change the base ISO for S-Log2 and S-Log3 from 3200 ISO to 2000 ISO. This will help produce cleaner images that are easier to grade. On top of that via a paid firmware update you will be able to shoot continuously at up to 120fps in full HD, no need to use the Super Slow Motion memory cache function.
These are all great upgrades for this little highly versatile camera.
By selecting Picture Profile 10 the camera will shooting using Hybrid Log Gamma. If you were to plug the camera into an HDR TV that supports HLG then what you would see on the TV would be a HDR image with an extended dynamic range. This should give brighter more realistic highlights and a quite noticeable increase in overall contrast compared to SDR (Standard Dynamic Range). There will be no need to grade the footage to get a perfectly watchable vibrant HDR image. The real beauty of HLG (developed by the BBC and NHK) is that it is backwards compatible with normal SDR (Standard Dynamic Range) TV’s. So feed the very same signal into a conventional SDR TV and it will look just fine. Skin tones will be a touch darker than with Rec709 and it won’t be HDR, but it will be perfectly watchable picture and most people won’t realise it’s anything different to normal SDR TV.
So HLG provides a simple very fast, direct HDR workflow that is backwards compatible with SDR TV’s. As a result you don’t need any special monitors to shoot with it, you can just monitor with existing SDR monitors, although it would be beneficial to have an HDR monitor to check the HDR aspect of the signal. HLG isn’t designed to be graded, although a little bit of post production tweaking can be applied, just as with Rec709. Bottom line is it’s quick and easy, no special monitors or skills needed – simples.
If you want the very best possible HDR then you should shoot with S-Log2/S-Log3 or raw and then grade the material in post using an HDR capable monitor. But that takes time and large HDR monitors are not cheap (for a small monitor you could use an Atomos Flame or Inferno). The FS5 will give you the ability to work either way. HLG for simple and quick, S-Log for the best possible image quality.
Hopefully we will see HLG rolled out to other cameras in the near future.
In case you missed the webinars I presented yesterday here are recordings of the 2 afternoon sessions. The first one on HDR, what is it and what does it mean for you. The second is a question and answers session on Sony’s large sensor cameras, from the FS5 to the F55. There were quite a few a6300 and A7s questions thrown in there too!
Hopefully I will be able to find a sponsor that will be able to make these a regular event.
