Most 3D movies are displayed in the wrong aspect ratio

Hitch

When I play some 3D videos on Oculus Quest 2 in DeoVR Quest, I see the video is deformed. Is there any way to change the aspect ratio to display the video correctly?

It depends on what kind of 3D video you are watching.

If it's a Half-SBS or Half-TB 3D video, you are out of luck. They will show it in a wrong way, no matter what you do.
If it's a full-SBS or Full-TB 3D video, you will have a great 3D cinema experience.
If it's a vr180 or vr360 video, you will love DeoVR even more. DeoVR offers the best compatibility for those videos.
To fix the aspect ratio problem, you need to re-encode the video from HSBS/HTB to Full SBS/Full TB. Not really worth the effort. Using another video player is a better solution.

Thank you for your reply. I don't really understand why the player doesn't support it? After all, most 3D movies are just compressed in half size. Can you recommend a player that can do this?

Free solution:

Quest built-in video player. It's primitive but works for 3d movies.
Bigscreen
Not free:
Virtual desktop ( best one I supposed)
Pigasus ( never used it.)
Skybox ( I am currently using it. Rock solid. Support SMB)

Hi everyone, thank you for the suggestions @philpw99. We will look into this.

Hi @philpw99 @Hitch do you have a sample of Half-SBS or Half-TB 3D video to check metadata and implement playback in DeoVR player? Could you please send a sample to creator@deovr.com? Thank you!!!

Kat, I know you want to help, but this is a feature that was in DeoVR before, and it was removed probably 2 years ago. I have been requesting it ever since. There is really no point in providing samples, if DeoVR devs don't want to implement this feature.
I already went from angry, denial, bargaining and finally accepted that, for some reason unknown to me, DeoVR won't support this. So I just tell everyone here don't waste time like I did.

philpw99 we have more resources now to add requested features. Would greatly appreciate your help. Thank you!

philpw99 Hello, we will implement this by adding filename convention, you will need to add _Half in the filename to get it working.

There is also some issue with metadata, looks like some legacy is triggering some weird aspect ratios, we are aware of this and fix is coming.

I will update this thread when I attach it to a release.

Sandi_DeoVR Has this been implemented? Will this work with an HLS source? How would I apply this? Would the _Half need to be in the path, or in the m3u8 filename? Hopefully not the latter, since my RTMP server that generates the HLS does not let me change the m3u8 filename from "index.m3u8". Is there any way to specify that it is HSBS in the json file?

philpw99

Well, what can I say ? Thank you ? Appreciate your help ?
Also I wish we don't need to add "_Half" in the file name. We just need to click a button to view the video in "half" mode.

BTW,
The current Aspect Ratio is already very strange. It doesn't follow the file's setting. It only follows the pixel dimensions.
For example, if I set a video file's meta data to be "16:9", but the video itself is 1000x1000 in pixels, guess what will happen? You will see a square video.
So yeah, weird stuff.

philpw99 You are welcome to leave a review, that's is all.

There is no known logic for reading metadata afaik, that's why I mentioned it.
But we will add it eventually.

I dislike the way DEO removes the format buttons when it auto-detects a format. Suppose you have a flat 2D video with "180" or "SBS" in the filename the video will play as a 180 degree or Side-by-side video, respectively, and you have no way to override the output format except to rename the file.

Sandi_DeoVR

bncecil I totally agree, we will make a copy on the player settings that doesn't hide.
