MPEG2 "multicut" tool?

[antzen]

Hi,

If I have one large recorded mpeg2 containing multiple parts that I want to cut away and merge the remaining parts into a new mpeg2 file, without having to recompress or anything AND keeping audio+video sync, what tool should I use... (see example below)

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx source MPEG2 
<-cut-><---keep---><-cut-><---keep---><-cut->
        xxxxxxxxxx             xxxxxxxxxx
Result:
xxxxxxxxxxxxxxxxxxxx

This would be ideal for editing out commercials etc.

Any tool for this? The ones I've tried can only handle 1 <keep> part...

vitec dvd tool box can do this easly .. m2 edit pro should be able to also ..

[antzen]

Are those doing this WITHOUT having to recomress the mpeg? I know that eg. Premiere and Vegas has to recompress...

TMPGENc Plus has a merge and cut tool in the MPEG tools section of the program.

How close do you need to get to a frame ?

@andkiich:

I've tried TMPGEnc and it's terrible in keeping A/V sync.

How close do you need to get to a frame ?

Actually I need it to be frame-exact, but I can live with "shortcuts" if it means to "copy paste" previous frames to keep the frames aligned with the stream, as long as I don't have to re-encode the whole mpeg2-stream.

Didn't download the trial since email registration is required, also it costs money (that I don't want to spend since it's very limited supply atm).

What I'm looking for is a freeware tool for this -small- task... but if I can't find it, I'll try to code a tool myself... however, this will consume alot of time (don't know that much about mpeg2 encoding/decoding at a programming level as it is...)

You are either a genius or completely crazy. If it was easy there would
be one already. I've been looking for 2 years

[BJ_M]

as i said above "vitec dvd tool box can do this easly" it does not re-render and it can cut on a p or a b or a i frame (re-renders 1 gop around cut) , it also can cut edit ac3 files and a few other things ..

[FOO]

It's not immediately obvious how to cut an Mpeg file with it.

.. nah, not a genious, but rather well versed in programming.. I'm actually studying the mpeg2 specs for this task... and I think I'll produce something like:

... it does not re-render and it can cut on a p or a b or a i frame (re-renders 1 gop around cut)

.. that is: re-render as small a potion as possible...

Why would I need a tool for this when there is such a tool like "dvd tool box"? - Well, to begin with... it's fun to code... but more important, it will be a small and fast tool that only do this.. (mpeg2 edit that is)... Let's see if I can produce something useful before I tire of the huge "information mountain" to climb before I know -what- to code...

I'll take a quick look at dvd tool box again, and see if it does what I want, if so.. then I may skip the whole coding business..

dvd tool box auto link points to the wrong thing (2 products with same name)


the auto link points to the wrong product

http://www.vitecmm.com/public/home/products/software.html?sess=1066770670

is the correct link -- totally different thing .. sorry about that

Oh, thanks, will check "your" dvd tb then

... and perhaps not... $399 for a tool that I will only use for editiing out commercials.. not my cup of tea...

but thanks anyway...

I don't know about the others, but I am anxiously awaiting your new MPEG2 cutting tool. Do you think that you will have it by Christmas?

Hmm, let me see, x-mas is in about 1.5 month.. that is plausible I think (I hope)... haven't really made any estimations for myself yet, but it would make a nice x-mas present, wouldn't it?

[FOO]

I feel much (A) better now and (B) much worse now.

(A) The correct link to DVD toolbox makes much more sense.

(B) The editor is $250

1) It costs money to buy it, but it has a free trial version
2)If you are that worried about the email part, just set up a yahoo email adress, I mean who doesnt have junk email adresses just for doing stuff like that?
3) If memory serves me right, they have a public FTP server, so you can bypass the email registration.

[BJ_M]

well the bad news is the price ...

the good news is that it is a lot cheaper than m2 edit pro ($1500)


i'm sure a lot of people would be interisted in a freeware version ..

[syeager]

I have looked for quite some time also, and have found nothing 'free'. However, I have have found a tool that cost me only about $15 including shipping from ebay. VideoStudio v6 SE DVD does the the best job of of editing commercials of any application I have tried. VS 7 is great too, but cannot find it as inexpensive.

Check it out. Good tool and no endless hours of programming and debugging.

BJ ?
Have you ever had a mixed 24/30 NTSC MPEG2 to play with ?
I'd like to know if that editor can remove middle sections without
causing audio sync problems.

[tomk]

Hi there,

I use tmpegdvdauthor wchich has EXCELLENT cut Function, I think even exactly on a frame.
I also use ULEAD Moviefactory2 "Extract video" if it has not to be so exact.

With both programs I end up in VOB ready for burning, sometimes I reimport the vobs.

Both programs do no reconvert or touch the material, they "simply leave it out"

HTH

nope - havnt tried that

[FOO]

That tends to completely confuse otherwise working editors.


TMPGenc Author will only cut on Gop boundaries.
...and even then there is a lot more going on than just
"leaving it out"

[BJ_M]

ill try it today
