vienas lygino 25i su 50p, kitas dabar lygina 50i su 50p.

tam kad lyginti vienodas salygas, prie vienodo duomenu kiekio, lyginti 
reikia 25p su 50i.

is ten pat:
Given a fixed bandwidth and high refresh rate, interlaced video can also 
provide a higher spatial resolution than progressive scan

are working with the industry to introduce 1080p50 as a future-proof
production standard. 1080p 50 offers higher vertical resolution, better
quality at lower bitrates, and easier conversion to other formats, such as
720p50 and 1080i50.[2][3] The main argument is that no matter how complex
the deinterlacing algorithm may be, the artifacts in the interlaced signal
cannot be completely eliminated because some information is lost between
frames.
