As shown, the hardware implemen tation of the MPCM encoder is able to compress up to 3,558 fps for HD-ready resolution (720p) or up to 1,581 fps for full-HD resolution (1080p).
In this way, a speed-up of 8× fps would be achieved and as a result, the MPCM encoder would be able to compress up to 12,648 fps for full-HD (1080p) monochromatic resolution.

Expert writing Tips
Best practice
Use the simpler and more direct verb "compress" without adding "up" unless you're referring to moving something higher during compression.
Common error
Avoid adding unnecessary prepositions like "up" to common verbs like "compress". This can make your writing sound awkward and less professional. Stick to the base verb when possible.

Ludwig's WRAP-UP
In summary, the phrase "to compress up" is generally considered grammatically incorrect. Ludwig AI confirms this assessment. While the intention is understandable – to describe the action of making something smaller or more compact – standard English prefers simply "to compress". Although examples exist in science and news media, these instances do not validate its widespread acceptance. For clearer and more effective communication, it's recommended to use "compress" or alternative phrases such as "to condense" or "to compact". Remember to avoid adding unnecessary prepositions to keep your writing concise and professional.
