How to Produce 4K and 2K Videos for YouTube¶
This guide shows how to
Producir un video 4K que se adhiera, tanto como sea posible, a los estándares de este formato
Publicar video en YouTube, que soporte resoluciones de hasta 4K, incluyendo 2K
Especificaciones¶
YouTube is describing quite accurately all the minimum requirements for uploading your material with the YouTube recommended upload encoding settings.
Brevemente, para los casos de 4K y 2K tenemos:
Tipo |
Video Bitrate |
Mono Audio Bitrate |
Stereo Audio Bitrate |
5.1. Audio Bitrate |
Resolution and Aspect Ratio |
---|---|---|---|---|---|
2160p (4K) |
35-45 Mbps |
128 kbps |
384 kbps |
512 kbps |
3840x2160 (16:9) |
1440p (2K) |
10 Mbps |
128 kbps |
384 kbps |
512 kbps |
2560x1440 (16:9) |
Nota
Newer versions of Kdenlive already have 2K project profiles (QHD) and 4K project profiles for UHD and DCI with a variety of frame rates. Therefore, the following steps are only needed if your Kdenlive version does not have them (seriously consider an upgrade) or if you want to change certain parameters.
Step 1: Create Custom Project Settings¶
Under
create a new custom project settings as follows.- Para 4K
Tamaño: 3840×2160
Velocidad de fotogramas: 60/1
Proporción de píxel: 1/1
Proporción de imagen: 16/9
Espacio de color: ITU-R BT.709
- Para 2K
Tamaño: 2560×1440
Velocidad de fotogramas: 60/1
Proporción de píxel: 1/1
Proporción de imagen: 16/9
Espacio de color: ITU-R BT.709
Notice that the settings for Project Folder, Video Tracks, Audio Tracks and Thumbnail should reflect your personal needs.
Step 2: Create Custom Consumer Profile¶
We are going to create a total of four profiles: two for 4K and two for 2K. This is necessary because despite their recommendations YouTube will not display videos in 2K nor 4K unless they are rendered at 30fps. Therefore, it is recommended to keep separate profiles for 2K and 4K, one each for 30 and 60fps.
Nota
The profiles have been created for Ubuntu 14.10 64bit, other distributions may have a different default directory for storing consumer profiles.
Under /usr/share/mlt/presets/consumer/avformat/Youtube_Advanced
(Linux) or C:\Program Files\kdenlive\share\mlt\presets\consumer\avformat\
(Windows) create the following files:
4K_60fps

Step 3: Create Custom Rendering Profile¶
In the Rendering window create a new profile.
