We are testing it out. Will follow up shortly

Iamthemulti now you have piqued my curiosity, what other settings does SLR encode with? 2-pass or 3-pass? veryslow or placebo? etc.

For h265 files: x265, single pass CRF 15, slow preset. Don't be fooled by the CRF 15 though because actual quality is significantly lower than that value suggests due to SLR's use of VBV.

Iamthemulti Quality impact for enabling fast-decode/low-latency (it's the same option that goes by different names) is minimal, and greatly improves playback compatibility.

Fast decode and low latency options are not the same thing. In x265 the low latency option reduces quality a lot because it disables B frames.

Iamthemulti When an encoder setting decreases quality by a couple percent you can usually get those couple percent back by just bumping up the bitrates.

You can bump the bitrates to compensate for the quality loss but it doesn't change the fact that the coding efficiency is lower after disabling the settings. Quality at the same bitrate is lower. The only reason to disable such settings is if you specifically want the tradeoff that they offer (e.g. less demands on the decoder at the cost of lower quality or increased bandwidth/file size).

        The difference isn't noticeable. Frame interpolation is much easier than resolution enhancement in VR, especially since Topaz Video Enhancer has been trained on 2D films, making it virtually useless for VR upscaling.

          Some questions about the 120 fps videos that you can find on SLR:

          • Using Q3 and HS, is it required to activate 120 Hz in both, Q3 and HS settings to fully benefit from 120 fps?
          • There are some examples like 6K 120 fps 36 GB, 6K Original 60 fps 88 GB. Which one of these is the better version, higher fps/lower bitrate or lower fps/higher bitrate?

            To fully benefit from 120 fps content the headset display needs to be running at 120 Hz. Just look at both the fps counter and the video info/timeline in HS. If you see 120 fps on the fps counter then the display is running at 120 Hz. If you see a frame rate of 119-120 in the video info then the content is 120 fps.

            There are some examples like 6K 120 fps 36 GB, 6K Original 60 fps 88 GB. Which one of these is the better version, higher fps/lower bitrate or lower fps/higher bitrate?

            It depends on what you prefer. "Better" is subjective here.

            Higher quality: the lower fps one
            Smoother motion: the higher fps one

              This is VERY wrong ! For Topaz Video AI there is NO any difference if it upscales 2D or "3D" films as 3D just combines two 2D films ... Actually my experience so far shows that 4K upscale to 8K looks noticeably better then 90% of the VR studios "original" 8K production. Shocking but true ! Just pity AI upscale takes so much time ... but this is the future for sure!

              Btw about the 120fps topic - have you guys tried to play 60fps vids with steam version of DeoVR trough Virtual Desktop
              at 120hz with SSW (Synchronous Spacewarp) enabled ? This really makes the 60fps vids looks noticeably smoother - feels very close to real 120fps ... So for me personally this is the ONLY ways to watch VR180 since maybe 2 years already .
              Once you get used to it that smoothness of SSW and then back to standalone headset video play i am always get the feeling the playback is little jittery ... So if you didnt try this yet i can highly recommend you try it and share your experience here ...

                  I disagree. VR upscalling makes films look cartoon-like. Have you seen the notorious Roll Coal?

                    The texture models require fine-tuning for VR. SLR's digital team experimented with this.

                        a year later

                        Well,any recent progress on this?

                        @doublevr oublevr"#p97528 How do you know that?50xx has not released in America

                        VRexplorer I don't get this article. It says SLR will re-encode all videos to 120 fps to match the abilities of the Q3 display but when people ask for the same thing the response is that the whole exercise would be pointless?

                            Frame interpolation is pretty damn good (if done right) and much easier than impossibly adding extra high resolution original detail that doesn't exist.

                            High res > frame rate

                            If you want both, then you go high res then do frame interpolation.

                                TemporaryName The issue is on quest 3 you can't have both. There is a decoding limit of 8192x4096@60fps. So if you want higher framerate you get lower resolution. I'm not against higer framerate. And with the rtx5000 series we can have both. Just saying that when 8k is the limit then resolution is much more important to me. But I we do agree on the basics
