applying same function on different data sets (video frames)

[Philly]

Good day guys,

I am trying to apply the same function to different data frames, I have a folder with approximately
900 frames from a video (jpegs) and want to apply the same function to all of them. The function
changes the brightness etc of the frames, which I then want to save as jpegs to proceed with my work.

Help would be so much appreciated as I cant find a solution.

Kind regards,
Phillip

Can you provide a reproducible example then?

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…
