Simple software program for converting H264 video in to flashvideo flv for website? my question is:

Which simple, lightweight, straightforward, easy to use software for Win7 can do the following:

A) import/convert on the fly MP4 (H264) movie into FLV (Flashvideo) and apply following:

B) Downscale FullHD footage from 1920x1080 into exactly half 960x540 pixels. 

C) Simple color toning or sharpess effects will be great

The MP4 movies are recorded in Full HD and come from an Android 4.0 device that captures footages in great detail. I tried Premiere but thats too heavy/expensive/too much)
Use Mpeg Streamclip, its an industry used conversion software that is reliable and fast, and free
