Grainy footage after zooming in frame to get closer shot.
When I zoom in on a clip to give it a better frame, the footage becomes grainy, is there a way to make to as sharp as it originally was before zooming. i am not zooming in very far. Would love to know best practice before I play with it myself.

Hi Eddi,
What you’re seeing is the camera increase the gain because lens doesn’t let in as much light when you’re zoomed in as it does when its wide. The only way to get cleaner footage at longer focal lengths is to make sure the subject is lit well enough so that the camera doesn’t have to use gain to get a proper exposure. The only other factor may be that your camera has a digital zoom function, which uses a smaller area of the sensor to increase the focal length. This can create artifacts.

Thank you for your response. I’m trying to make a some badly shot footage that was given to me to edit – look better. Was just hoping I could do something more in post. Oh well, there’s only so much you can do with some footage.

I’m guessing you’re referring to the loss of quality when magnifying a clip in a sequence?
While the gurus around here may have some tips on how to get better results, there’s no way to enlarge the image and yet maintain the same image quality – the detail just isn’t there. High Def and progressive footage will be more forgiving, standard def and interlaced footage is less.

No much to do in FC, apart of setting “Render Motion Effects: BEST”.
If you are working with DV footage, rendering in Prores and “High Precision” should help too.
Motion should do better and for sure After Effects do it.
Cheers,
