| I use windows movie maker. Look in your programs as you should have it.
From that program you can load everything, even printed banners etc. To edit the videos you can use this program too. Just drag the line to where you want the video being edited to stop where you want it.
When I am starting a video first I write down changes or words I want to accent by time. ( like 1:12 'to fly' etc). Then I review my videos and if I can use one but needs to be edited, I rename it like " cut at 25 secs" ( 25 seconds), and that makes things faster.
Remember with all videos to mute the sound on the video or it will over play the music. Its under the top bar under audio. You click on the video you want to silence first, then go to the top bar to audio, and click " mute"- then it will silence it but keep the music. |
