I shot quite a bit of 3D video with the iphone 15 Pro Max last weekend on the cruise.
I really put it to the test.
Compatible 3D that can be viewed on traditional 3D TV sets that were popular about 10 years ago can be viewed and the 3D depth is very accurate. Apple really did a great job on this.
While I don't have an AVP and have no plans to buy one, the MetaQuest 3 can also convert the Apple Spatial video and audio in the iphone 15 Meta Quest app while it uploads your video to the Files 3D Spatial folder. I only saw one issue and that is there appears to be a maximum recording time for these conversions. I managed to upload a 14 minute program to the Meta Quest 3 and it looks fine. Quality is quite good.
I just connected my Meta Quest 3 to my iphone with a USB C cable.
For You Tube I used the Spatialify 3rd party app to convert to Half Side By Side and then that was uploaded. Again there was a size limit to save the file when converted. The longest clip I could do was 24 minutes. But I just sliced up my 54 minute Hiro 3D SBS into 3 parts and then later frame matched edited them together in Adobe Premiere before uploading to You Tube. I don't know if You Tube keeps the 3D meta data for Meta quest or not. However, there are ways in the Meta Quest to view SBS in 3D. Not sure if AVP can do that or not.
