Edit Elementary (Mpeg2) Streams in Womble Mpeg Video Wizard?

[nbarzgar]

Hello,

I vainly tried to find something in the forum:

Is it possible, to cut/edit elementary streams in Mpeg Video Wizard?
Or is that only possible in Cuttermaran, at least the fast and easy way...
I know - more or less - how to edit programme streams.

So does anybody know?

Thanks.

yes you can .. same as program streams..

[nbarzgar]

But in the Input-Monitor the audio is not played, when adding the video elementary-stream. So how do I make Wizard "get my meaning"?

Tell you the truth, I did not try yet since I could not imagine, how Wizard would cut the correct places...

[BJ_M]

elementary stream video only - no audio

if you have two elementary streams (video and audio) , mux them together and do you editing and then demux


to cut the correct places - is up to you

[nbarzgar]

Thanks, I guessed that - now I am sure!

Very fast answer...

It would have been nice to have the possibility. Sometimes I want to change the sample rate of a video file, afterwards use it in DVD-lab Pro to author. For both operations you need them demuxed (DVD-Lab demuxes, of course, but for sample rate change...s.a.)

So if I have to change the sample rate of an mpeg, I would go:

1. Demux
2. Change sample-rate
3. Mux
4. Cut in Wizard
5. Demux (again)
6. Author

If I cut first and change the sample rate later, I sometimes get a/v-synch-problems, the other way around - in 9 cases out of 10 - I don't.

[BJ_M]

sample rate ? you mean bitrate don't you ?

i.e. re-encode

[nbarzgar]

No, sample-rate, but I was not precise: I meant the sample-rate of the audio-stream of the video-file. Sorry.

That is: .mp2 with 224 bps/44100 kHz to .mp2 with 224 bps/48000 kHz.
(for example)

Just encode to elementary streams.
Cut in Cuttermaran.
Load into DVDLab.
3 steps, instead of 6.
Better yet, cut in virtualdubmod, frameserve to encode, author.
Still 3 steps, but faster because you're not encoding the portions you're going to cut anyhow.

[BJ_M]

it would still be the same number of steps in mpeg2vcr

and more in vdubmode as you would have to re-encode, which you want to avoid in the first place

[nbarzgar]

If I ENCODE before, of course I encode to elementary streams. But these days I have the occasional VCD and SVCD, I want to put on DVD...

I prefer frameserving with AviSynth, by the way...
