Custom refresh rates for video?

Respectfully, I disagree. I think it’s more “if it drops video frames, a small percentage of the user base won’t buy an 8K”. Honestly, as long as it doesn’t drop a LOT of frames (or it stutters), I’m not even sure a typical viewer would even notice (or care). My DVR drops frames sometimes (due to shitty Charter cable service), my wife only complains if it’s more than 1 sec or so of dropped frames.

I doubt I’ll even use my 8K to view movies and I’m sure that there are others like me.

That being said, I understand this is a very important issue to you, but that doesn’t mean that it’s particularly important to other users. I’d consider it a nice-to-have feature, but given a choice, I’d MUCH rather have a 90 Hz refresh rate (instead of 80 Hz).

I am guessing you were not around for DVDs when they introduced 3:2 pull down.

The point is. Playback will not make this headset fail. Failure to be able to run VR programs due to core features not working will. As it has not caused Rift cv1/Vive or Vive pro to fail.

Its marketing is vr headset not video player. If it supports Video Mode then custom refresh is bound to work.

60hz as I said will be important to BW if works as expected.

Okay while I do agree with @Enopho on beating dead horses.

I give you 1 challenge. As I spent 20m of different wording in google; I can find no “importance” of video playback in VR regarding refresh rates etc. Save Bandwidth issues of hi def streaming.

So Challenge find an Article that supports your PoV. Keep in mind also in the community you are the only that is leading this as a must have now answer.

Otherwise wait for testing to be complete. I will however ask the testers when they have time to test vid playback. Just keep in mind no results will be released until pimax authorizes testing results release.

Well come to think about it, the 110 degree fov of old style headsets wasn’t sufficient for me to watch movies like in a theater. When I got the screen big enough to my liking, it didn’t fit exactly within that 110 degrees. So when we can watch giant screens all the way from left to right on the 8K 200fov, maybe that introduces a whole new experience worth watching movies in. Especially if they can be 3D too.

I had a dream this morning about wearing the headset and basically preferring the world inside it over the real world. Thing was damn sharp too but the 200 fov sold it. This headset is going to be a real game changer I think.

3:2 pull down is HORRIBLE! It was done out of pure necessity. I’m glad we are over that. There is no necessity to fix the refresh rate at 80Hz. Allowing the user to set a custom refresh rate is very likely easy to implement. I want to use the 8K to watch movies so I would much appreciate also 50 and 60HZ beside the default 80Hz. That doesn’t mean Pimax should drop everything and focus entirely on this feature alone. But I hope they will implement it at some point.

At the time 3:2 pull down worked fine. But later of course wasn’t good for new displays.

Before 3:2 pull down DVD playback was horrible.

Some form of pull down is used everywhere. Netflix do it prior to streaming, then your TV gets to process it (good or bad) too…

Judders have and will always be an issue for many due to the difference in original film vs display device.

Other’s have confirmed the importance of 60hz. Right here. In this very thread. It’s a very real issue. If you don’t believe me, believe John Carmack.

If this headset goes live without a 60hz mode, it will be yet another thing for the critics to harp on (if you thought Pimax was gonna get picked apart for the whole “8k” thing, just wait to see what reviewers say about this).

So @deletedpimaxrep1 just pretend like you never saw this thread (too late to chime in now), and just please confirm in the next update that 60hz mode will be supported in the final version.

Ummm… I just re-read this thread and the only one who seems to feel that 60 Hz is very important is you. Please point out any references that I missed.

Also, let’s put JC’s quote in context, “‏The backlight flash time is adjusted, the brightness and colors should be the same, just less flickery at 72fps. 60 fps immersive video looks much much better than 24 fps!”

One, he likes 72 FPS and two, 60 FPS is better than 24 FPS. No where does he state that 60 FPS is better than 80 or 90 FPS for video, at least in the quotes I found. In fact, 72 FPS is better for movies, since 72 == 3 x 24 and most movies are shot at 24 FPS.

I recall somebody here had a finger or two on the pulse of the Smooth Video Project…

Has there been no experimentation with full on resampling to a different refresh rate, rather than just discrete interpolation? (basically almost never displaying a regular real i, p, or b frame as is, but every one being a proportionally inserted one)

Again you missed the point of posting article links.

Yes there were some users who asked if this could be implemented. But nowhere did they make claims the headset would fail without this feature request.

I did diligence on my part trying to find even 1 Article that supports the need for this to be a must. I am not dismissing your concern, but merely pointing out the populous on a whole does not believe this is a must have festure or no one will buy a VR headset.

There are far more important things for the team to have worked out before looking to implement things like different refresh rates. First need things like driver optimizations & stability, ipd adjustments, tracking optimizations, Ease of use & setup. As I said core features, then advertised features & then requested features.

And as I mentioned if BW works as well as intended; 60hz support could be ideal for posdibility of running higher settings in programs.

As I have said will however ask the Testers to try Videos in the headset.

If you have some specific ideas ie 180/360 videos & a particular reg/3d video player in mind can ask them to test when they have time.

This isn’t about articles or opinions, it’s about math. You either understand the math, or you don’t. There is a reason why engineers (way smarter than either of us) are going out of their way to support multiple refresh rates in their HMD’s, it’s time to accept it.

So to recap (just in case anyone is still confused): If the headset’s refresh rate can’t match the video, you will have dropped frames. If you release a next gen headset without support for the most popular video format (60fps), your headset will fail (because the competitors headset won’t have this limitation).

And if you don’t understand the importance of video (porn, high quality experiences for low hardware requirements, social media/video sharing, easy streaming content, etc…), then you shouldn’t be participating on a VR forum.

Okay closing topic as requested as you cannot provide links.
