Transcoder minimum size and bitrate levels.
We have minimum requirements on video source files in order for the transcoder to be able to make each size format in HLS and MP4:

(The following applies to both MP4 and HLS)
In order to create a 1080p file, you will need a source file at 1080p tall and at least 8000kbps bitrate.
In order to create a 720p file, you will need a source file at 720p tall and at least 5000kbps bitrate.
In order to create a 480p file, you will need a source file at 480p tall and at least 3000kbps bitrate.
In order to create a 360p file, you will need a source file at 360p tall and at least 1500kbps bitrate.
In order to create a 240p file, you will need a source file at 240p tall and at least 1000kbps bitrate.

If your source file is not at least 8000K, the 1080p version will not be created and the operation will be skipped (you'll see an error in the operations telling you why the error occurred and why it was skipped). We can lower these minimums at your request, but they are there to prevent low-quality files being used to make higher-quality files, which just uses up disk space.
