Edit Video to make shorter and change some titles

A few years ago we created a 4 minute video for our platform. The video can be seen here: [login to view URL] now we want to use the same video but reduce the length and change some of the titles of positions, links. We intend to keep the following parts 0 to 19 seconds (Try to shorten) 25 to 40 seconds (Change position from Chief Marketing Officer to Chief Executive Officer) 1:30 to 1:37 3:33 to end (Change URL and Risk Warning) This will make a one minute video. Please note the music will be affected so that does need to be considered. And where a scene cannot be blended, maybe just take audio and use the video from 0 to 19 seconds as imagery. The video does need to look like a single finished article. Please add the word Cat to show you have read this far, no cat will lead automatically deleted. It would be good to see a video you may have edited (orginal and your edit)
