Great video. Those mod crashes were awesome
I really like the widescreen, steady zoom and the picture quality - what camera are you using?
Music rights: most of the time I just risk it and if it gets blocked in the UK I either add another track without re-editing or I re-edit with the new music. The most sensible thing to do is to choose the music, put it in Movie Maker, post on YouTube and see what happens
before you start editing.
Almost all the songs that are blocked in the USA are also blocked in the UK, so that shouldn't be a problem with being visible here but not in the States. What is a problem is Germany - most of my vids are blocked there. Is it something personal?
Another option is to go with obscure 'cover-band' versions of songs which rarely get flagged up by YouTube or are not copyrighted. Sometimes they are better versions. Some 80s German punk bands did some great covers - and they don't get blocked in Germany or anywhere.
Slow-Mo: easy to do in Movie Maker. Go to Video Effects, scroll down and drag "Slow Down, Half" onto the clip. If you drag it again, it will slow it down more (see
Jim's Luck Escape from the
HO:GP for slo-mo in action). Using any of the effects more than once doubles the effect - brightness, ease-in etc.
Movie Maker is amazing for what it offers, but can crash a lot the more editing you do. So, always save after every small edit. I also have an old version of Adobe Premiere. I sometimes use it to edit a clip and then use that in Movie Maker. Premiere is also more flexible for editing the music track.
