I want to start producing videos and looking around the internet for usual bitrate ranges (VBR) and H.264 profiles and levels for Web Video exports.
I found some guides with Vimeo and YouTube and construct my own export settings, based on the previous mentioned guides.
I am producing the videos mostly within the EU, so I am shooting my videos in either 25p or 50p to reduce the light flicker effect due to the power frequency (50 Hz).
I came up with the following settings for HD-ready, Full-HD, (true) UHD, and (true) 4K.
- 1280×720p25.000, 5-10 Mbps, H.264 High Profile Level 4.0, HDp25
- 1280×720p50.000, 10-15 Mbps, H.264 High Profile Level 4.2, HDp50
- 1920×1080p25.000, 10-20 Mbps, H.264 High Profile Level 4.0, FHDp25
- 1920×1080p50.000, 15-25 Mbps, H.264 High Profile Level 4.2, FHDp50
- 3840×2160p25.000, 40-60 Mbps, H.264 High Profile Level 5.1, UHDp25
- 3840×2160p50.000, 60-80 Mbps, H.264 High Profile Level 5.2, UHDp50
- 4096×2160p25.000, 40-60 Mbps, H.264 High Profile Level 5.2, 4Kp25
- 4096×2160p50.000, 60-80 Mbps, H.264 High Profile Level 5.2, 4Kp50
The container format will be MP4, with the moov atom at the start of the file (fast start). I will introduce the moov atom as a post process (ffmpeg), since my primary transcoding software does not support the moov atom at all. The audio is AAC-LC, stereo with 96 KHz and 320 kbps.
My question is: Are those settings suitable for better quality Web Video presentation? Did I miss something while merging the various guides on how to setup the transcoding process?
I would like to point out again, that the above mentioned settings are for the Web Video exports only. When I author Blu-ray releases, I will do much higher bitrates etc.. However this question is only about the Web Video presentation.
