The Panasonic GH4 is the first 4K camera I have tested. I have lots of good things to say about it and will have plenty more sample video along the way. For those new to 4K video (including yours truly), I wanted to take a few minutes and break down what I have learned about exporting 4K video using Adobe Premiere Pro CC and share some presets that I created for exporting 4K footage for YouTube 4K delivery.[youtube https://www.youtube.com/watch?v=Lt44v-6Khd4&w=640&h=360]
YouTube will display up to 3840 x 2160 video footage, which is commonly referred to as UHD or 4K UHD. This is a 16×9 format that will match the output of most of the 4K cameras on the market today. If you happen to shoot in true 4K, you’ll be scaling that 4096 x 2160 (a 17:9 ratio) into YouTube’s 4K window and end up with letterbox footage.
YouTube has a page dedicated to advanced encoding settings for your video files, which include settings for 4K videos. For standard quality 4K footage, YouTube recommends 35-45Mbps bit rate in a .mp4 file using an H.264 codec, which should be configured as follows:
- Progressive scan (no interlacing)
- High Profile
- 2 consecutive B frames
- Closed GOP. GOP of half the frame rate.
- Variable bitrate.
- Color Space: 4.2.0
One of the things I like about Adobe Premiere Pro and Media Encoder is the built-in presets for matching your footage for a variety of uses after outputting the file. Unfortunately, Adobe has yet to build 4K presets into the standard YouTube or other end use categories of presets.
You can create your own using YouTube’s recommended settings above. Or, you can download some presets that I have made and tested on YouTube. Use the following links to download the presets. (Just right-click the link and choose “Save as…”)
To install the presets, go to Media Encoder’s Preset Browser and click the Import Presets button.
