We could use the Alpha Multiply node, or we could simply decrease the RGB channels by the same amount as the Alpha. This is, because we need to multiply our RGB channels with the Alpha to see the correct transparency. If you look at the Alpha channel, you will see that it does get darker, but the text stays visible (at least were it is completely white). Try this, deselect R, G and B in the BrightnessContrast node and reduce the Gain Slider. Fusion is like AfterEffects in Adobe ecosystem. Fusion comes as a standalone software but also comes integrated in Davinci Resolve. Fusion is also offered by BlackMagic Design but in two ways. You might be wondering, if we simply want to change the Alpha Channel, why do we need to change the brightness on the R, G and B channel as well? Basically, Davinci Resolve is equivalent to all of Video Editing software in Adobe Video Editing Suite. If you look at the Alpha Channel we can see, the bright parts are getting darker, meaning the pixels above in the Red, Green and Blue channel are showing transparency. You can see that we can select and deselect the R(ed), G(reen), B(lue) and A(lpha) channels separately. Drop down a BrightnessContrast node after your node branch.
