Hey guys, shot this for a friend, b4 i go about cc, i wanted to know what you see.

Image is darker on mac, but seems closer to what i saw when shooting on lcd, but on windows pc and even on 720p flatscreen. Flatscreen had the mac hdmi feed, but still appeared brighter.

What do you see and which is more accurate, pc/flatscreen or mac?

shot in avchd, converted in cineform to avi, output 1080 mpg4.

thanks

Looks really dark to me on a calibrated NEC monitor. My iMac is currently being repaired so I can't check it on that for about a week.
 
ok cool, so why does it look so much brighter, even over exposed on acer monitor and flatscreen?........any thoughts?
 
yeah, for sure it was dark, i used a 17-50mm 2.8 (2.8, 1/50, 200 iso) the room was pretty dark and cramped, pro lights werent possible, so i lit it with 5 clamp on work lights with 100 watt cfl's.......sadly its all we had to work with. when you say lift the blacks and mids.....what exactly does that involve, i'm a lil bit of a newbie with cc....lol.
 
anything i can do with the monitor to calibrate the image, i tried to adjust brightness but the image is still blown out
 
It looks like you're on a WIN machine? Are you editing in Premiere?
You need to put a Color Correction filter on the footage. Raise you blacks and mids a little bit.
Too much and the image will get washed out. I'd leave it a little dark is all.
 
actually its vegas....but yeah, i know the filter you are talking about.....it goes "high, mids, lows" correct?......so the blacks would be the lows?......if this is due to acer, it really complicates my editing process....lol
 
If your monitor is unreliable for color correction, I would at least get a look at your vectorscopes so that you have some idea of what your exposure and dynamic range are looking like.

However, depending on how much the video was underexposed you might not be able to do anything even when lifting the blacks.
 
thanks guys i really appreciate the input, guess ill do the best i can and trust the image i get on the mac
 
Also do a search for "gamma shift" if the problem is difference between players. It seems like with almost every program on the PC or Mac you run the risk of having colors and brightness change, especially if there is an RGB/YUV conversion. QuickTime especially is notoriously problematic.
 
Your editing software has Scopes, learn what they are & how to use them. No matter the monitor you use, your levels will always be perfect.


ps. That footage is at least 3 stops underexposed
 
Yo. I work as a colorist (Avid Symphony) Your can save that footage. Curve up the mids, try not to boost up the blacks at all or too much. That's going to make the image milky. Work it up from the mid range and then if you have to blacks. Keep some of your image at 0. If not you got milk.
