Software suggestions for compressing to 4K mp4
Hi,
I’ve received a request for a set of specs that is pretty new to me, and I’m hoping somebody can shed some light on what software might be able to handle converting to this. Some of the specs (like 60Mbps/60Kbps) seem to exceed the available ranges in Compressor. Some of them (like level and profile) don’t appear to be selectable in Compressor. Any recommended software or approaches to get these exact specs?
Thanks!

Either Telestrem Episode or Sorenson Squeeze should be able to handle these. Compressor is great, but not optimized for these outputs.
Neither has (I believe) a preset for Profile/level – you need to adhere to what those mean.
Profile is mostly about Color Space
Level is about Size + Data RateI’d download both, and go at creating a finished file.
Best,
