i have a few film files on my pc that is in the format of FLV and MP4 and i want to cut portions out of it and save them in the same format as they are originally.

i want software (hopefully free) that does not re encode these clips (so it will be fast) i have a program called 'Video ReDo Plus' which can do this but it will not except these formats, i also have 'editing' software but this re encode the video, which i don't want as this takes a relatively long time.

i also have Avidemux but this is a bit of a hit and miss affair with sometimes its 'key frame' error warning.

i have seen lots of free downloads for these kinds of programs on the net, but only to find out after installing that they re encode the clip after cutting (i might as well use my video editor in that case)

thanks all.
