interesting, just did some research on hfr movies, avatar series and titanic are also 48p, gemini man 120p. james cameron and ang lee are no fools neither.

when i watch these well known hfr movies, i never have a second thought that these movies are junk made by non artists non scientists amateur dps. i just immerse myself in the movies and enjoy the story lines. i have watched lor and hobbit many times, about equal to god father trilogy and matrix trilogy. never had a negative thought about them. the only thing for me to complain is that there is no more episode. lol.

if 24p is so critically fundamental in cinematography, then lor and hobbit and gemini should have been total disasters and have had huge loss in money making. on the contrary, they are so successful, envied by many holly wood directors and dps.

not sure about the universal hate thing. lor and hobbit series are regarded as one of best series, not just by me, but by most of the viewers. peter jackson is not a fool himself.

the displaying technology is improving, most 4k tv now has 60 hz or 120 hz or even 240 hz, youtube has 4k 60p, the trend will follow. new generation of viewers used to youtube 4k 60p never care about 24p. in the near future, 24p will be a nostalgic look, like betacam, lomocam, sepia, etc.

tried again. in a typical in car temp, gp 12 shuts down at about 15 min even duration is set to no limit. turning on ac to maximal scale in window/front oanel/driver mode, seems solve the issue. man, it is such a "cool" experience.

totally agree. i use hanheld most of the time, because of its convenience. but sometimes when i look at my footage from a tripod session, i am always amazed by the image quality, the cam movement is so nice, wide angle panning and tilting are almost perfect. i also don't like grain, no matter how "organic" it is claimed, it is just noise. i think the real filmic characters are high light rolling off, and the color, which are why alexa and f35 excel in either category. the shallow dof holy grail has been already busted since 5d2. not much left for film.

gen z boys and gals grow up with 1080p or 4k 60p. to them, the so called 24p motion cadence aesthetics is just old school. there is nothing magic for 24p, just the old school grand daddies' habit who watch too many old holly wood movies. these grand daddies' grand daddies like 16p no sound movie more than 24p sound movie for the same reason. lol. time changes.

24p is hailed as cinematic. it was just a frugal approach at the time of film days. 5k 60p of gp 12 is so smooth. seeing is believing.

maybe it is better to have raw action cams, overheating may be a less issue than the current crop. it seems anti intuitive, but it is not. if sd overclocking is not activated, 1080p vista vision 5d3 ml raw is less likely to have overheating issue than 5d3 stock 1080p or 5d4 etc.

gp 12 overheats so quickly. in car without ac on, it only records 15 minutes and shutdown. if it is hot summer, wo ac, probably less than 5 min.

for tiny action cams, 10 bit log is the way to go. in cam painting is very thin. cam body is small, no room for powerful gpu. no 10 bit log is a critical weak point.

Gp12 battery uses up quickly. Especially after installing gp labs firmware.

Thanks a lot. Will try the voice isolation.

thx boss. so we don't need adjust ev, or have -1 ev. depends on test results.

for gp12 or maybe earlier ones, dr is more on the dark less on the highlight. not a pro expensive sensor.

He fixed at iso 100, so maybe iso 100 is gp 12's native ISO.

So probably two modes need to be set to use gp log. One in sunny scene to protect highlight, which uses the default ae with the secret -2 ev locking in. Another in cloudy or indoor scene to reduce the noise in the shade, either don't use the gp log, or use +2 ev for each shot.

gplog is 68% IRE, according to this video.

Interesting, gp actually integrates -2 EV into its ae in log mode. So we actually need to do +1 EV to lose a little bit of highlight, but reduce a lot of shade noise. "You might wonder how to color grade or color correct GP-Log. The problem is that no matter how good you are at color grading, the exposure needs to be right in order to get good results. With the release of Gopro hero 12 Black, Gopro also released GP-Log or Gopro Log to the official firmware. But they implemented it with a secret EV comp of -2. This is why GP-Log is too dark in every shot. This video explains why a -2 EV comp is too low, and how to fix it with gopro labs."

I think this is going to be even more disrupting as the new raspberry pi 5 is just announced. I figure that cinepi 3 based on pi 5 may do 8k raw on a s16/1-inch sensor, at about $500.

I think the major critical advancement of the last decade of the camera development is being able to put 4k or 6k into one tiny body, together with hfr to 60p or 120p, ibis, video af, etc. Maybe in another 5 years, raw codec on a u43 or s35 or 1-inch sensor will come to these small bodies, then a red epic in a true pocket cinema camera body is possible. Any manufacturer does this first will scoop a lot of money, like what Red experienced around 2010.

Interesting, Labs app has shutter as degrees, but the official app has 1/x sec. At the current status of auto exposure, I use -1 EV, from the histogram, seems working, pushing the histogram to the left. Right now, not sure if GP12 is smart enough to do auto exposure for glog. If not, maybe manually set to -1 EV to -1.5 EV, let the ISO flow from 100 to 400, auto shutter speed, it may work for glog. Really want to know the native ISO, or some graphs of DR versus ISO numbers. Come on, GP should release something like this if it considers itself pro level. Why don't Hollywood DPs complain about this? They use GP in their features too.

Thanks, will use NR=1

By activating extra features, iso and shutter info can be live on lcd screen. i try to manually control iso, like min iso 100, max iso 100, seems working. so, my question is: what is the native iso of gp 12 to have greatest dr? i set shutter to 180 degrees, seems shutter auto changes all the time. so it is auto exposure by default. my question is: can manual exposure be activated? can shutter changes to 1/x sec instead of degree? if only auto exposure is allowed, does gp12 itself knows how to expose for log? or end user has to use ev compensation to manually adjust?
