Hi,
I have a problem. I record how I play computer games and have a small area with my Facecam in the lower right corner. Yesterday I experimented a little with my light and that’s why the picture on my facecam looks terrible. Small pimples glow as if someone were holding a laser pointer in my face.
I would like to only edit the small area with the facecam for the colors and leave the rest of the video untouched. Is that possible? And how?
Many Thanks.
Hi @Chuck_Norris, Import 2 copies of your video, and stack them directly above each other - one on V1 and the other on V2. Mute the top video.
Add a Crop: rectangle filter to the top video and crop the facecam section. (select “transparent” so the bits on the outside of the facecam are transparent). Use the boundary box to select just the area you want to keep.
Change colours of your facecam by adding, say a lightness or hue or saturation filter. This will only affect your facecam. The rest of the video will show through unchanged.
Hi @Chuck_Norris
If you prefer to use only one track, there is also this solution:
But I prefer the solution proposed by @jonray, because at the moment, it is a lot easier to modify the size and shape in the Crop: Rectangle filter than it is in the Mask: Simple Shape filter
May I suggest in the future recording the Facecam separately simultaneously, without embedding the Facecam in the gaming screen during play, then synchronizing and combining the two recordings in Shotcut.
I made a singularly boring video in that way of me playing Sudoku this evening…

…along with an incredibly low-quality, unedited documentary of how I made it using a screen recorder and a webcam recorder…

The entire project is at…
Dropbox folder for “gamer” project.
This method provides a much more flexible control over the Facecam window in post-production video editing.
That worked perfectly. Thank you.
Glad it worked!
That is a really useful way of reminding people (including me!) of the mask:apply filter, introduced in December 2018:
Thank you for this useful technique, it will help a lot of users.
Mask: Apply is an amazing complement to Mask: Simple Shape (and Mask From File).
But I really wish the Mask: Simple Shape filter will get an upgrade one day. It deserves the same on-screen transform tools as the SP&R filter. And manual transform settings in pixels instead of percent.
J’ai celui-là, mais je doute qu’il fonctionne sur les nouvelles versions.
Fonctionne sur 20.09
I have this one, but I doubt it will work on the new versions.
Works on 20.09

As it’s off topic, answer by PM
Keep in mind, that anything after these 2 and before Mask: Apply can also affect the alpha channel. For example, Crop: Rectangle with transparent:
Often you want to start the mask completely opaque - as in this case. From Mask: Simple Shape defaults set width and height 100%. From Mask: From File defaults, set threshold 100%.
Effectivement, cette solution de contournement fonctionne. Même si cela nécessite d’ajouter un filtre supplémentaire cela peut être plus rapide d’utiliser les coordonnées en pixels de Crop: Rectangle plutôt que de galérer avec les pourcentages de Mask: Simple shape
Merci
Indeed, this workaround does work. Even if it requires an additional filter, it may be faster to use the pixel coordinates of Crop: Rectangle instead of the percentages of Mask: Simple shape.
Thanks
Useful trick ! Thank you
