I am new to video. I have a HandyCam (CX405). I don't like trusting in the auto-white balance because it is variable and unpredictable, but changing manually between indoor/outdoor or doing re-calibrations with a white paper can be a real pain in the neck because in that camera everything must be done through one single small button that can be pressed or pushed in four directions to navigate menus.
My idea is leaving one fixed setting (either indoor or outdoor) and then doing the white balance in the post-processing stage in blender.
I know that some things must be done right at the recording stage and if you screw up there is little you can do afterwards, e.g. using a wrong shutter speed. And I know there are some other things that are done internally on the recorded footage inside the camera and you could do them equally well in the post-processing stage manually, and I think white balance may be well be one of them because essentially consists on a numerical multiplication of the values stored in the C_R and C_B components of the video that the CMOS has already recorded. So, probably, you will not loose any information if you do the white balance later in your editing software instead of doing it in the camera.
Is that wrong? Will I regret it later?
