The HDR version of the GTA 6 trailer does not have more graphic details than the SDR version

This article was written for the first time on Gimfa website: news, reviews of games, cinema, movies and series in the link HDR version GTA 6 trailer does not have more graphic details than SDR. The technical analysis of the HDR and SDR versions of the new GTA 6 trailer reveals an interesting fact: contrary to popular beliefs, the HDR version does not necessarily contain more graphic details and textures, and the fundamental difference between the two versions is simply the way it is displayed.

The technical analysis of the HDR and SDR versions of the new GTA 6 game trailer reveals an interesting fact: contrary to popular beliefs, the HDR version does not necessarily contain more graphic details and textures, and the fundamental difference between these two versions is limited only to the way of processing and displaying the brightness, contrast and depth of the color spectrum.

Shortly after the release of the latest demo of GTA 6, a number of image processing specialists and HDR technology analysts put the visual effects of this title under the microscope. The results of these careful analyzes show that although the HDR version of the trailer offers a brighter output and a more cinematic atmosphere to the audience, it apparently does not display more visual and geometric information in the bright parts of the image than the standard SDR version.

In this regard, one of the analysts known by the username MusaRenoDX, after matching and comparing HDR and SDR images frame by frame, has come to the conclusion that the bright parts of the image in both outputs have almost the same level of detail. According to him, this remarkable similarity can be a testimony to the use of the Inverse Tone Mapping technique by the creators; A mechanism in which the narrower SDR image is converted to the wider luminance range of HDR by software processing, without actually injecting new image information or additional texture into the original source.

On the other hand, Filippo Tarpini, a prominent expert in color processing and HDR technology, has pointed out some potential flaws and anomalies in the way colors are displayed by analyzing this trailer. In his investigations, he has found that in one of the sequences related to the pool, the blue color of the water in the extremely bright parts finds a tangible deviation towards the violet color spectrum. In addition, in some of the image frames, the undesirable phenomenon of Color Banding (the creation of visible staggered bands at the border of changing the gradient of colors) is clearly visible.

According to this expert's argument, the occurrence of such disorders is mainly rooted in Tone Mapping algorithms; A process used to convert and map brightness and color information. He also hypothesizes that Rockstar produced the HDR images of this show through secondary conversion of the SDR source; A scenario that, if repeated in the final version, can be criticized as one of the technical weaknesses of this work.

However, these analyzes should not be taken to mean that HDR technology in GTA 6 is ineffective. By expanding the dynamic range of lighting and creating a deeper contrast between the darkest and brightest points of the scene, the HDR feature is able to make the lighting effects of the game look more realistic, richer and more cinematic. However, one must accept the technical fact that increasing brightness and contrast dynamics is not necessarily synonymous with increasing geometric detail, improving the quality of textures, improving 3D models, or increasing image resolution.

The important point in this is that all these evaluations have been made based on a commercial and compressed trailer, and a definite judgment about the quality and final implementation of HDR technology in a commercial product will be a premature and hasty action. There is a strong possibility that the final version of GTA 6 will use completely different calibration settings and image output, displaying much richer visual information in the shadow and light parts of the environment. Rockstar Games has also remained silent on these speculations and has not provided clear technical details about the mechanism of HDR implementation in the game.

GTA 6 game will be released on 28 Aban (19 November) for PlayStation 5 and Xbox Series X/S consoles.

The GTA game series has an adult age rating; Therefore, it is necessary for families to monitor the access of children and teenagers.
