Показать описание
Just testing the video quality of my Note 4 on T-Mobile, model number SM-N910T3. Camera is a 16 megapixel, smart ois, fast af, life hdr, F2.2 aperture, 1/2.6" camera size.

Recorded the video using UHD @ 30 fps.

It appears the camera interface will stop recording when using 4K after 5 minutes. It appears this is to stop the phone from overheating, which I saw no signs of overheating while recording and they enforce this limit to stop you from maxing out storage space.

File format: YYYYMMDD_HHMMSS.mp4 (Ante)

I uploaded this video directly off the phone using the YouTube app if that makes any difference. No editing or anything. It appears during movement there is some pixelation and fuzzy artifacts which watching the RAW video file does not have, I blame this on YouTube's lower 4K bitrate, than what it was naively recorded at. The higher bitrate is needed for the extra information needed during motion.
