72024PN setting looks dark

Hi There

I've recently been shooting alot of interiors in the 72024PN mode and noticed how much considerably darker the image is versus shooting in the 720p60 or 1080i modes, also the scene file settings contribute their own murkiness to the image.
I use alot of lights and usually have the iris fully open but still the murkiness exists, usually having to end up boosting the brightness in FCP with colour correction.
Part of the reason I like to shoot in 72024PN mode is you get more footage on the P2 card is this because its more compressed?

Am I doing something wrong? What settings would any of you suggest to overcome some of the murkiness I'm experiencing shooting in 72024PN mode? Or should I be shooting in a different mode for interiors?



Thanks in advance
 
720p-24pN means the progressive images are shot Natively. It records only 24 frames a second, which is why the P2 cards get more recording time as opposed to recording 30 or 60 frames a second. This is also what gives the HPX and HVX the ability to record variable frame rates.

That sounds quite strange that the 720p60 and 1080 are lighter... Since the camera is exposing less frames a second at 24p, the sensor has more light for each exposure per second, which means the image should be brighter... I would check your scene file settings. They might seem subtle, but they can make a world of difference to the final image produced. Have you gotten Barry's HVX/HPX Book? Are you using an HPX170, HVX200, or 200a?

And the mode you shoot in shouldn't be dictated by the location, but rather by other factors like final delivery format and production processing logistics (card storage time, etc etc).
 
Check your shutter speed. On an HVX or HPX170, in general, 720/24p should be slightly brighter than 720/60p or 1080/60i. On the HVX, going to 720/60p or 1080/60i results in about 1/4 stop less sensitivity.

Make sure your shutter is set to "off". The shutter speed is relative to the shooting mode you're in, so if you set the shutter to (say, for example, 1/100) and then just change the recording format from 720/60p to 720/24p, you might find that the shutter is now set to perhaps 1/250. And that would explain a lot.
