4K resolution video output is one of our top requested features. Squeeze Server 3 offers preliminary 4K support to through two specific 4K Presets, one for H.264 and one for x265. At this time 4K support is limited to these two specific presets.
Below is a list of the source files we have tested (Input) and the presets we created and tested with (Output). Of these we cannot guarantee that every machine/customer will be able to get this to work properly, Squeeze Server 3 is not build to fully support 4K Source and Encoding.
Again, 4K support is very limited and should be treated as a exploratory format, not something to implement into daily workflows.
