encoding or not encoding?

Post by Sepu »

I was working on these TV clips during the last weekends, and I've found some interesting things...

First, from my SA rips I get a AC3 audio, as always.
I wanted to edit every clip and merge them into a single one, but if I do it with Vegas, I must render everything.

So my idea was to use Tmpgenc plus, but since this program doesn't work with AC3, I first had to convert the AC3 audio to MV2 and them multiplex every single video with the MP2 audio.
At the end of this process, I merged them all, but the completo output MPG gives some problems with the audio. Sometimes you can hear it, sometimes no...it's really weird :rolleyes:

I think the easier solution is finally a rendering with Vegas, but with that I will have a re-encode.
For what I know, multiplexing or demultiplexing doesn't include a re-encode of the videos.

Any suggestion?

As for me, two ways.
If you're having problems with sound don't merge, imo. Only, when you start authoring, make connections between the previous and the next video, in that case player won't come back to the root menu after watching every single content. So demultiplex every single file.

Or, if you really want to use some fades in and out (etc), and if you have all files in the same video resolution (right?), then rendering in Vegas, with the exactly same settings for video (res, ratio, field order etc) will not take much time (it's basically a copy of video stream). If you set it right, the video won't be re-encoded again. And Vegas supports AC3. So, what you need, is 2 times more space on your HDD.

thanks for your suggestions Krzych :)
I can try to just edit and don't merge the files with Tmpgenc, and then add them into DVD-Lab for the authoring.
I will let you know here.

Good evening

I've never used TM-smth, but once you edit your files, shouldn't you save them as new video files? IMO, same process you'll get as merging in Vegas. But in SV, you will have them together in one file, without problem, like you wanted to have :)

Whenever I try "No Recompression" rendering in Vegas, I can't make the crossfadings work properly.
Video crossfades, but just after the fading the scene jumps back again which causes an out of synch problem.

I use SV8, don't know if this is still a problem in newer versions.

i use Vegas a lot and some times if you try to put it as SR, you need to put it manually...

i have a best idea... try to use WOMBLE MPEG EDITOR.... is the best MPEG2 manage ever, this have smart rendering and work itself, and you can do cross, fades etc... and put them in all single files... i use it tyo manage MPEG2 and later TMPGEnc for authoring, i use Vegas just for Multicams or for wotk with sync audios... trust me, WOMBLE is the best, is an small program.

Yeah, there is a way you can edit and then save a new MPEG file without re-enconding, but I checked the "new" single edited videos with the MP2 audio and there are problems already on them, so it isn't the merge function the problem.

I think I should use the one suggested by Leo or finally just rendering in Vegas...

I think that when u add fades, u always need to rendering and "compress"...in a way or another...

Have 8.0 also, never had problem like yours ;) Rendering settings must be exactly the same as properties of video files.

trust me, i manage Vegas and this one, and for edit single MPEG2 is the best program and easy, you can make all these things also that you manage with Vegas on this program, like Fade, cross fade and some other effects and you will reencode just that effect part and not the whole video. :rolleyes:
