Question

Is it possible to apply an AUTO LEVELS / COLOUR across all frames?

I know AUTO effects are full of problems, I even so .. is there a way to make a auto effect only ever sample a single frame and then apply it across the entire clip?

More info

If you have a clip and apply "auto level" you it seams to do the level effect on every single frame. This can produce flickering effects. There is an option called "temporal smoothing" that can lower this problem, but it greatly increases render time, not a little bit but by a huge factor.

If you apply a manual Level or Colour grade and do not animate the settings then those adjustments you do apply to the entire clip, you get better looking frames than some others but you get no flickering and can improve the general look significantly.

The Ask

Is there a way to drag out the AUTO LEVEL effect, but somehow get a look at the values it is using to copy into the manual levels effect or some other way to force AUTO LEVELS to only sample the 1 frame you apply it on.. so it acts like the manual level effect but still "automatically" grades for that first time.

Thanks in advance

    Hi! I would love to have that feature (since years). Maybe asking Adobe to add a checkbox to "keep actual values" after adding the auto levels effect. Didnt find a feature wishlist in the site 😞

    Auto Levels is now an obsolete effect.

    There is no way to get exactly that.  But you can simulate it for color, at least.

    Add an Adjustment Layer over all the media and switch to the Color workspace.  On the Basic Correction tab of the Lumetri panel, you can use the WB Selector on a single frame to apply a white balance correction to the entire sequence.

    There is nothing comparable for brightness and contrast, though.  You'll have to do the work manually there.

    1. haven't tried it but maybe auto levels in photoshop with video, it may only change first frame?

    2. you could make a "fix it" lut by sampling a before and after auto-levels PNG. I use this free lut utility. https://sellfy.com/p/aQ1y/

    then apply as a LUT as adjustment layer.

    3. if you are asking for an auto black point, white point, saturation, and gamma plugin, you might be able to modify my after effects flicker/color/exposure auto stabilizer template.

    4. if you want an instant match frame feature, either speedgrade's match frame or RE:Match - RE:Vision Effects

    5. if you want to grade really fast, lumetri is pretty fast with this semi-automatic white balance preset.
