  • ffmpeg - color-grading video material AND display original source as picture-in-picture, using -filter_complex

    5 octobre 2019, par raven

    this is my first post on this forum, so please be gentle in case I accidentally do trip over any forum rules that I would not know of yet :).

    I would like to apply some color-grading to underwater GoPro footage. To quicker gauge the effect of my color settings (trial-and-error, as of yet), would like to see the original input video stream as a PIP (e.g., scaled down to 50% or even 30%), in the bottom-right corner of the converted output movie.

    I have one input movie that is going to be color graded. The PIP should use the original as an input, just a scaled-down version of it.

    I would like to use ffmpeg’s "-filter_complex" option to do the PIP, but all examples I can find on "-filter_complex" would use two already existing movies. Instead, I would like to make the color-corrected stream an on-the-fly input to "-filter_complex", which then renders the PIP.

    Is that doable, all in one go ?

    Both the individual snippets below work fine, I now would like to combine these and skip the creation of an intermediate color-graded TMP output which then gets combined, with the original, in a final PIP creation process.
    Your help combining these two separate steps into one single "-filter_complex" action is greatly appreciated !

    Thanks in advance,
    raven.
