Blur a moving area in a movie on Mac OS X

Question

Note, there's already a question on this regard, but it's totally useless.

I need to blur, or put a small opaque mask to a moving object on a movie I took, I am using Mac OS X. Clearly, I don't want to shell out a lot of money for something so simple, so getting Adobe Premiere or similar software is a no go. I could however consider paying a small software (max 30 dollars) for this specific task.

Answer 1

There is absolutely nothing simple about masking blurry objects in video unless you shot it in front of a chroma key backdrop. If it's not worth more than $30 then it's probably not going to happen unless you have a friend in film school who'll do it for free.

Answer 2

If the object doesn't move too much then you can use iMovie. Your other option might be to use the trial version of Premiere if this is a one off thing you need to do.

Answer 3

Great video editing software for your Mac is Final Cut Pro. If you don't want to pay for that you could probably do that in iMovie.

Answer 4

Another option is to use a tool like ffmpeg to extract all the frames from the video (as a jpeg images). You could then use any image editing software to blur the frames individually. Then, could use ffmepg to reassemble all the frames back into a video. Yes, it's a very tedious way to do this, but it's free ;)
