Не е съвсем така за AVCHD стандарта... той съвсем спокойно си покрива 50/60Р
съжалявам за дългия цитат на английски:

1080p
In the professional and prosumer markets, AVCHD camcorders such as the Panasonic AG-HMC150, the Panasonic AG-HMC40, the Sony HDR-AX2000 and the Sony HXR-NX5U, are capable of recording in all three high definition formats: 1080i, 1080p and 720p. Sony camcorders do not support film-like frame rates — 24p, 25p, 30p — in 720p mode.
In the consumer market, 60 Hz versions of the Panasonic HDC-SD9/HDC-HS9, Panasonic HDC-HS100/HDC-SD100 and Canon HF S21/HF S20/HF S200 models are capable of recording native 1080p24 video.
In 2010, Panasonic introduced a new lineup of consumer AVCHD camcorders (HDC-HS700, HDC-TM700, HDC-SD700, HDC-HS600, HDC-SD600) with 1080-line 50p/60p progressive-scan mode (frame rate depending on region).[19] While this mode is not compliant with current AVCHD specification, it uses the same compression schemes for video and audio, the same container files and the same folder structure as AVCHD-compliant recordings.[20] Panasonic advised that not all players that support AVCHD playback could play 1080-line 50p/60p video.[21]
In 2011 the Panasonic HDC-HS600 and HDC-SD600 models were replaced with the HDC-SD800, while the HDC-HS700, HDC-TM700, HDC-SD700 were replaced with the HDC-HS900, HDC-TM900, HDC-SD900 respectively. Most of the features remained the same, including 1080-line 50p/60p progressive-scan recording. This coincided with introduction of Sony consumer AVCHD models (HDR-CX360V, HDR-CX560V, HDR-700V) capable of 1080-line 50p/60p video recording. Additionally, the Sony camcorders are able to record native 1080p24 "film-like" video.
Panasonic models have no visual designation of progressive-scan capability, whereas the Canon models have a prominent 24p Native Progressive mark.[22] Sony models capable of 50p/60p recording or of 24p recording are identified with appropriate marks as well.
