I just want to do some simple scene cutting.
I use avi demux to edit my avi files.
Can I also use it to edit mp4 and mkv and m4v files ?

Avidemux is a free video editor designed for simple cutting, filtering and encoding tasks. Tasks can be automated using projects, job queue and powerful scripting capabilities. It supports most video formats like DVD, VOB, AVI, DivX, XviD, WMV, MPG, MP4, AVI, MOV, MKV, DV, FLV.
But it wont work perfect with all mp4 and mkv. Expect lots of crashes....
Try Video to Video Converter. Under the Tools button there's a "commercial remover", which I assume doesn't limit you to editing out just commercials. It should let you edit and rejoin lots of different file types without re-encoding.
It's been a while, but I think you open the Commercial Remover, then use it to open the file for editing. It'll only edit on keyframes (which is normal unless you re-encode), which means you mightn't always be able to edit exactly where you want to, but it'll automatically choose the nearest keyframe when setting the edit points. In order to edit more exactly you'd need to re-encode. Once you've finished editing, a new window opens in order to choose the encoding method. You'd select "Direct Stream Copy" in order not to encode anything, then use the normal "Convert" button in order to get Video To Video Converter to edit the video and rejoin the sections for you.
It might be possible to get Video To Video Converter to do "smart cutting", ie it'll cut the video exactly where you tell it to and just re-encode the area around the cut point if necessary, but I've not experimented with it myself to see if it'll do that, or whether for precise editing you need to re-encode everything.
I don't use Video To Video Converter for much actual converting myself, as it gives you virtually no control over any encoder settings, but for those "odd jobs" which most other GUIs won't do, it's a very handy program to have installed.
Thanks but I am not interested in using some obscure program that no one has heard of!
There are lots of them out there.
But I want to use one that is well known and gets updated and has good support in the forums etc.
I am also not interested in "It should let you edit and rejoin lots of different file types"
MP4, AVI and MKV are notoriously difficult to cut exactly. Most edit to keyframes and the best free one I've used is:
It does AVI and MKV, not MP4 unfortunately.
It's from a commercial company and is updated regularly.
Errrr..... there's even a portable version you can try by simply downloading it and unzipping it. No installation necessary. What have you got to lose, besides some silly assumptions? Either it'll split your files, or it won't. I wouldn't have recommended it if it hadn't worked successfully for me, whether you've heard of it or not. I've even used it to remux video and audio from one container to another while splitting/editing at the same time.

Sorry I did not mean to insult or upset you.
But over the years when I have asked for similar requests some people push a program they are selling or involved with that I have never heard of or seen mentioned.
And of course I come to this forum because it has so many experts on it and I was hoping there was such a program out that that does what i wanted, but it seems there is not.
Is suppose it makes sense that one program cannot work on entirely different codecs.
Thanks for the help and I may try that program.
