I have never edited anything before. I imported a video and cropped its dimensions. I also want to cut some fragments, insert images with a fade in and fade out inbetween and correct the lighting. This all should be possible (although I haven't confronted it yet). I tried to render the writer just after cropping it, but it fails and I don't know why. It says another active render is rendering.
Thank you very much for your help in advance.
