  • How to get consistent lighting/color over jump cuts?

    Posted by Kevin Hickey on February 5, 2019 at 3:24 am

    New to the forums here and just invested in starting to build home/office studio and started a new channel for my wife.

    I started filming with the Canon M50 for my wife’s new Youtube series but when editing in post (FCPX) I noticed there are shifts in lighting and color extremely noticeable in jump cuts across takes.

    I’m shooting in manual mode and my studio lights stay set. Can I (and how) do I fix this in post or is my shooting setup messed up?

    Here’s a video if it might help to see what I’m trying to talk about.

    A good example can be found at the jump cut between 1:40-1:43. All takes filmed within a 20-minute window. 

    Any tips would be appreciated!

    Did you check and make sure Auto ISO and Auto White Balance are both disabled? Also, it appears that you have some natural light leaking in the background at least; could the sun be moving in and out of clouds? That would cause small but noticeable exposure changes.

    Thanks for the tips Blaise.

    I believe I did turn off Auto ISO and WB but I’ll double check to make sure.
    After noticing the changes in lighting I started wondering about the light from the windows too, although I wouldn’t assume such noticeable changes would happen so quickly. I’m going to try and cover the windows and see what happens.

    Any other tips or insights are certainly welcome!

    Thanks everyone!

    You’d be amazed at how quickly natural light can shift–when you’re shooting outdoors, the sun goes behind a tree or cloud, and boom, two full stops of exposure change. Since it’s not your only source, it doesn’t have that much effect, but enough to be noticeable–I’d wager a beer that’s what’s going on.

    Hi Kevin,

    Is my assumption correct the jump cuts you reference where cut during editing in FCPX? And, not some other method, like manipulation of the Canon, such as start/stop recording?

    You have some cuts that the lighting stays the same from previous to next and then some as you reference.

    I can see how the change of secondary natural light could have caused the difference if you have stopped the recording then started, and then cut some of the end and beginning of those two clips in FCPX.

    Best Regards……George
