How can I edit translated video on a Mac? There is a movie on my Macbook which has some some inappropriate scenes that I want to edit so I can watch the movie with my family. 

I know how to cut scenes (trim) using Quicktime but this will confuse the translation timing on the film (.srt file)

I am wondering how to make the scene freeze (fixed) while the unwanted scene is playing or better, a program that would adjust the timing of the subtitles to match scenes cut so that we didn't have to fast forward through whatever the "censored" still frames look like?
I use SubMerge to load and sync subtitles to movies. I generally look for subtitles in SRT format. You can usually edit the subtitles texts inserting (or removing), pauses or blanks. A difficult part is that it's not uncommon for subtitles to slowly get out of sync with the film as the latter progresses. Adding - or removing text is really handy to restore synchronization. It is a bit of a laborious process though :)

Once I have the stuff in sync, then I too use Handbrake to change formats if necessary. Hope this helps.
