After buying a 40$ 2012 video editor with bad avi decoding giving smeared colours of videos from my two digital cameras I reinstalled my old Movie Plus 5. It comes with OK avi decoders, and a separate install of (free) Xvid encoder allowed Movie Plus 5 to export in xvid .avi format in addition to the default mpg, mov, avi and wmv formats.Install of the (also free)k-lite basic codec pack made import of variuos mp4, 3gp and flv files possible after ticking "allow 3 party codecs" under options.A 2010 patch is on Serif website, and with chroma key, many other advanced features and running stable on a low spec. XP computer this software is still great for small projects

When using the EXPORTING part of the program as it is so slow, I tend to do it last thing at night before retiring. Trouble is, when I get up during the night, I go and look how its getting on, only to find the exporting has stopped and a pop up box is on screen asking me if I really want to stop. This annoys me, as time is wasted through inaction of the program.
I'm only a novice at this movie authoring but I find it relatively easy to get to grips with. Therefore I well recommend Serif MoviePlus 5.
