White balance across a project

[Davidk]

Versions 2018 and esp 2019 both have enhanced color correction features. And the 2019 tutorial on how to use while balance has an excellent explanation of what white balance is. However, a read of the user guide makes it clear that the balancing effort is per clip: select it, find the whitest of white areas in the clip, and select that point/area to be the white balance reference. So, if you have a more than a few clips in the project, this balancing effort could get tedious.

And yet, in the note to the Tutorial (downloadable, which is how I got them), there is this statement
quote
Also, different cameras have slightly different color grades, so if you’re using a few different clips in your project you’ll want to balance your whites so that pure white looks the same across your clips.
unquote
The tenor of the statement is that balancing white once can apply to all clips in a project. And as a result, what I am wondering is, is there a single method (un-documented feature??) of establishing white balance for all the clips in a project?

Anyone care to comment on this

Each clip having a slightly different white balance would require a different correction.
The process using the colour picker reads the clips white bits and decides say a 2 % change in the colour temperature is required.
The next clip with a greater colour cast needs 4%
If you expect the program to choose which to apply to all, which does it use as neither will be right for all clips, if it averages at 3% then the effect may be near enough but not accurate.
As far as I can see it has to be done one at a time.
Setting the first clip then using Copy and Paste Attributes is always an option, even so will not apply the right correction

Recording done outside are usually pretty good, indoor recordings can be troublesome with different lighting types, and its these that we should take a little time to set the cameras white balance, usually with pre-sets or a manual approach by recording a white screen to set white balance.

And that quote does not say you can apply white balance to multiple clips, i believe should say....
“so if you’re using a few different clips in your project you’ll want to balance your whites (one at a time) so that pure white looks the same across your clips”

I'd forgotten about copy and paste attributes, so that reply is indeed useful. But otherwise, I'd sort of suspected that doing white balance one clip at a time would be the way. The user guide has never been a place for workarounds.
