Digital zoom

[Peter Goldwing]

I see only old posts regarding this subject,
A few days ago I filmed my son surfing. He is a beginner and its rare and far between when he catches a wave. I had a good shot of him but kind of faraway. How I zoom into this video for whats is worth. I understand it might be jerky or pixeled but I want to give it a try; I play the video on Mc Book Air using Quick Time player. It has a zooming option but nothing happens

You can zoom with any video editing software. Options vary from software to software.
