Playing 4K Ultra HD
Videos on Fire TV
Only Amazon
Fire TV (Gen 2) and Amazon Fire TV Edition support playback of 4K UHD media. To
support 4K playback, you must adhere to the supported output resolutions, DRM
systems, and codecs for 4K UHD content.
Apps that support Ultra HD video will be
certified by Amazon to ensure they meet the required customer experience.
Typically, certification takes a couple of weeks.
When you
submit your app, add a note that it is 4K-enabled. Most likely in your app’s
description, you would already highlight to users that your app offers 4K Ultra
HD media playback. But adding a manual note will also let Amazon know to apply
4K performance testing on the app during the certification process.
Amazon Fire
TV (Gen 2) is expected to stay mostly in Full HD (1080p) mode at 60 FPS, even
on TVs that support 4K UHD format. Fire TV (Gen 2) switches to 4K UHD mode only
for 4K UHD content playback.
Fire TV
Edition’s hardware decoder supports playback of 4K @ 60 FPS. To play 4K @ 60
FPS, the timing requirement of media pipeline is aggressive and the app may not
be able to render 4K frames at 16 msec interval due to thread and process
scheduling limitations of the kernel. This may result into frame drops and a
sub-par movie experience. To get the best out of the hardware, use Tunnel Mode
playback. For details, see Tunnel Mode Playback.
