EVCT: editing more efficient APP
For example, when you draw a picture things like zoom out, brush size or density can be changed sensuously.
If you are video editing you may want to change back/forward, volume up/down or adjusting an effect in the same way.
By using EVCT, you don't need to buy expensive tools for this purpose. You can simply download and set up your device and be able to reach the same performance as an high level editing studio equipment.
To use EVCT, download and execute the program on your PC.
