When watching movies on the Quest I experience a lot of judder with the built in player Oculus Galery, Oculus Browser, Skybox and Youtube. Only Netflix seems to display movies without jumping frames: flying in logos, like Universal, seem to have no "jumping frames" in the Netflix App.
You can test this for yourself with the file "ft-23.mp4" from these test videos (https://fotovideotec.de/frameraten/downloads/ft-standard.zip
Take a look at the cars driving from left to right after the stripes (starting at 00:20). Here's the same clip on Youtube for testing in the Youtube App: https://youtu.be/o80pN7zLhIQ
Unfortunately this effects 99% of all movies since 23.976p is the standard frame rate on Blu-rays (because it the standard for cinema movies).
It seems that the standard Quest player (not the Netflix) tries to display 23.976p on a 72p display without proper conversion. Normally the player should speed up the video a tiny bit to 24p so that every frame is displayed 3 times. The player then also has to speed up the audio and sometimes drop audio frames (which is not noticible) - not playing audio faster and altering it with a higher pitch (which some people would hear that, because music pitch sounds off). This speedup is unnoticable and leads to smooth playback. All reasonable players on PC do it like that.
Can you confirm the judder on your Quest? I'm wondering why I didn't find any discussions about that, because it is really obvious judder which is not something only movie buffs will see and it decreases quality sooo much ...
