I like the effect in the attached screenshot,
Video in the background, mostly obscured except for the text.
I have tried a couple of things but just cannot find the right combination.
Using text filter I find I can set the alpha channel for the background however it also applies to behind the text.
I tried a mask (Black and white image of the text) but without success.
You have to put the background video Vi
Then your texture V2
Then create a V3 text
turn off tracks 2 and 3
Export as image name it (mask text)
Extend or delete track 3
track 2 apply mask filter from file
custom setting, use the previously created mask.
Alternate method, no external application or chroma key necessary.
Text simple, white font on black background. Export frame.
Add color clip, used black, on a track above the video/image.
Use mask from file with custom option. Open the exported text frame.
Opacity filter set to 60%
