[gentoo-user] editing MPEG2

[Uwe Thiem]

Hi folks,

is there a light-weight MPEG2 editor (preferable in portage)? I don't need 
anything fancy, just something to cut off a bit at the begin and the end of a 
file.And no, kino doesn't like MPEG2.

Did you take a look at the mplayer and mencoder oprions ?

Kino 0.8+ should be able to import anything that ffmpeg can handle, but
I've found that this doesn't always work. There was a thread on this a
couple of weeks ago, after which I started using projectx for this.

try ttcut it is not in portage, but it is in the gentoo sunrise
overlay, i use it for cutting mpeg files from dvb-recordings. the only
thing you have to do before cutting is to demux it to video and audio.
you can use projectx (which isc available wich portage) for this job

My experience too has been that avidemux works well.  However, only
the latest version; an earlier version didn't work well.   My
installed version is: 22000-r2, from an overlay:

   http://forums.gentoo.org/viewtopic-t-382903.html

Kino didn't work for me either.

avidemux has improved immensely in recent versions.

I didn't realise until this thread that kino now supports ffmpeg
compatible streams. I must try that. 

kino will do fancier transitions etc - avidemux is more for cutting the
odd bit out and transcoding the result.

if you are happy to may money then main actor does a reasonable job of
editing/transitioning and transcoding.

If you don't care about the quality of the cutted scenes projectx, is
what i reccommend.
But projectx and many other editors are only capable of cutting on a I-Frame

The video cut theory is explained at
http://www.radonmaster.de/robernd/tMPEG.html unfortunatly it is in
german

If you want to cut frame accurate (cut on B- and P-Frames too) i think
ttcut is the better choice, here you can enable encoding mode so it
uses mencoder (and you don't have to read the immense man page for
mencoder) to recode the video. Not the whole video is encoded, only a
maximum of 14 pictures (i think 15 pictures is the standard GOP lenght
for MPEG video) around the cut mark depending on where exactly you
want to cut

i don't know if kino or avidemux can handle this now, if anyone knows
better please tell me!

Generally I find that I want to cut at a major transition - eg the
adverts coming on. At a major transition there is usually an I-Frame.

Maybe it is the german tv as for many movies i have recorded i have to
cut on B- and P-Frames to avoid pictures from the adverts.

Emerging projectx doesn't work here. It complains that it can't find any JDK. 
I have this under /opt:

drwxr-xr-x 8 root root 192 Oct 14  2004 blackdown-jdk-1.4.1
drwxr-xr-x 3 root root  72 Dec 18  2004 blackdown-jdk-1.4.2

drwxr-xr-x 8 root root 192 Dec 25  2005 blackdown-jdk-1.4.2.03

What now?
