# PS Home supports the following video codecs:
# MPEG-4 Part 2 MPEG-4 Video Simple Profile - up to Level 3
# MPEG-4 Part 2 MPEG-4 Video Advanced Simple Profile - up to Level 5
# MPEG-4 Part 10 AVC H.264 - up to Level 3.1
#
# AVC H.264 Level 3.1 720p, 30fps is supported only in video spaces. Other types of spaces or scene types except
# game spaces support up to Level 3.0.
#
# PS Home supports the following video container formats:
# MPEG-4 Part 14 MP4
# MPEG-2 Part 1 Transport Stream TS
#
# If you require audio, you can add an AAC audio track to the container. For more information on MPEG-4 Levels and
# supported resolutions, see Screen Memory Usage.
#
# The recommended tool for encoding video for PS Home is FFmpeg or an application based on FFmpeg, though any application which
# creates files which adhere to supported MPEG-4 standards should be compatible. For best results, make sure that both the video
# width and the video height are multiples of 16.
#
# Video is automatically stretched to fit the screen, so you dont need to encode video at the correct aspect ratio
# for it to display correctly assuming that the screen is the correct aspect ratio. This makes it easier to
# select video dimensions that are multiples of 16.
#
# Selecting an Appropriate Bit Rate
# Although PS Home is able to play video with bit rates up to the maximum allowed for each supported MPEG-4 profile level up to 8
# Mbps for MPEG-4 Video and 14 Mbps for AVC H.264, bit rates this high are rarely required to maintain a high level of video
# quality.
#
# The bit rate required will depend on the following factors:
#
# Resolution: High-resolution videos require a higher bit rate.
# Frame rate: Higher frame rates require higher bit rates, note that there is no visible benefit to using a frame rate higher
# than 29.97 frames per second fps as this is the frame rate of the PS Home client.
#
# Video format: MPEG-4 Video requires higher bit rates than AVC H.264 at the same resolution in order to maintain similar
# quality levels.
#
# Video content: Video files with large amounts of fast-moving footage will require a higher bit rate, whereas video
# containing mostly static backgrounds can use a lower bit rate without sacrificing quality.
# For these reasons, it is not possible to specify what bit rates should be used to ensure high-quality video in all situations,
# but the following examples may be used as guidelines when encoding video:
#
# Format Width Height Frame Rate fps Bit Rate Kbps
# MPEG-4 Part 2, Simple Profile 176 144 15 64
# MPEG-4 Part 2, Simple Profile 352 288 29.97 fps* 384
# MPEG-4 Part 2, Advanced Simple Profile 352 288 29.97 fps* 768
# MPEG-4 Part 2, Advanced Simple Profile 640 480 29.97 fps* 1536
# MPEG-4 Part 2, Advanced Simple Profile 720 576 29.97 fps* 2048
