Encoding and keeping the orginal audio

Postby burntresistor » Wed Jul 05, 2006 4:18 pm

I dunno if I did this right cause everytime I keep geting 1gig for a 2min 30 sec clip.

1st) I converted the ac3 audio to wav using besweet
2nd) Just ran it like a normal encode in vdub using lagarith also using the orginal frame rate which is 23. somthing.

This I know won't run in primere pro what am I doing wrong in general to make this clip a smaller size and usable. Will increasing it to 29fps
screw up the audio and make it out of synch?

I don't plan on using this clip in its entireity,but I like more to work with when I start.

I know I can use Xvid to make it more compressed but i guess the real problem is the audio synch after changing the fps to either 24 or 29

Okay, I did what you listed myself and got the following results using an 8 sec clip.
(I encoded in both lagarith and huffy)

1) The file sizes are: 19MB for largarith and 51MB for huff
2) Largarith is slightly out of sync and huffy is in sync.

What I did was, in DGindex, under Audio, I chose Decode to WAV as the output method.

I then imported the AVScript into VDubMod and placed the WAV in the stream list and simply chose the two codecs without modifying anything. But for me, the FPS was 29.97 because I didn't de-interlace, which is what you may be doing.

I belive the guide may explain this. Here is the <a href="http://www.animemusicvideos.org/guides/avtech/24fps.html">Link</a>

I wasn't sure to add to this thread or just make a new one, anyhow.
I know in pro there are 1st and 2nd audio positions and so on.
The problem is the volume on my mp3 is naturally higher than
the wav. How do I turn down the volume of one and increase the other?

Select the audio clip and go to the effect controls tab. There's a volume control bar ready to be used.

BTW, there is no difference in audio gain according to the audio layer. Putting the clip in Audio 1 or Audio 100 will still make it sound the same, and with the same volume.

Thanks...but back to my orginal problem yes it does make it 29fps when I took out the interlace code for the video. I notice the interlace problem and its very obvious in my pro and my test exports I've done. So,
basically It's either I find a way to interlace at 29fps and still have the audio sync or not use it(which I really wanted to do)


My project settings in pro are for 29fps and I don't think adding somthing thats 23fps would work.

I would suggest normalizing both files with a third-party program, like CDex or Audacity. Chances are, that's what has already happened with one of those files and not the other. Normailizing both should solve that issue. Good luck.

I thought about this problem and it's not the audio that needs to be changed because dgindex doesn't slow down the fps, since it’s taken directly from vob files. The problem I have is with the video needs to be 29fps and when through interlacing to get rid of the after effects and lines. Maybe I’m just repeating myself …..

So, basically I encode the video without audio in vdubmod and then add the audio afterwards? I downloaded Audacity which I thought was just an audio program.

Wait, now you confused me. Recapitulate, please.

If your original source was 29.97 fps, then to deinterlace without changing the frame rate, use something like KernelDeint(order=1, threshold=10), TomsMoComp(1,5,1), TDeint(mode=0,order=1), SmoothDeinterlace(tff=true, doublerate=false), or FieldDeinterlace() instead doing IVTC (Telecide + Decimate).

I assumed each of those new codes was to be used with what I already had except the last but now everytime I open the avs it closes the vdubmod

LoadPlugin("C:\Documents and Settings\Administrator\Desktop\encode\dgindex\DGDecode.dll")
MPEG2Source("C:\Documents and Settings\Administrator\Desktop\encode\t4.d2v")
SmoothDeinterlace(tff=true, doublerate=false)

Telecide(order=1)
Decimate(cycle=5, mode=3, threshold=1.0)
