Quality of the video

[kevincador]

Hi,

We're playing locally stored videos. We tested with good quality video (found on VLC's website and on the web). Some are 400mb 4K video.

Compared to the experience on VLC on a Mac with the same videos, the quality of the rendering seems bad.

Tested on an iPhone 7 Plus and on an iPad Mini 2. It may have something to do with the @2x or @3x scale.

Thanks for your feedback.

Kevin

Hi @kevincador,

I was having the same issue so I decided to make some changes that you can see here (in my pull request): https://github.com/NYTimes/ios-360-videos/pull/53

Let me know if you find any trouble. Hope it can be useful!

Wow this is perfect. A huge improvement here. Thanks a lot for this pull request. Hope it gets merged and pushed to Cocoapods soon.

@nachonet we tested other 360 player and we found out that ios-360-videos is still rendering the video with a quality loss. This is due to the zoom level. Seems that with other 360 player, we are a bit farther from the scene. Since we have a small zoom, the quality decrease.

How would one play with the zoom level of the "camera" to improve the quality of the image?

There are a number of ways the quality of the rendering can be improved:

• Increasing the number of segments used to render the sphere onto which the video is mapped. If high enough it essentially gets rid of deformations
• Altering the size of the scene (SKScene) to something more appropriate than 1280x1280
• activating anti-aliasing on the SCNView
• possibly activating 'jittering' on the SCNView
• altering the field of view to make it wider
