Frameserve to Vegas

[rbautch]

I've heard a good way to do a Pal to NTSC conversion is to frameserve to Vegas, then tweak the audio by stretching it. Anyone know how to do this? I tried and got a Vegas error that it was looking for some sort of plugin.

[alsyed]

no need to tweak the audio. Just load the video and audio up, set your project to ntsc, and it will do a nice job of converting, it will look smooth. I use it the other way for high quality ntsc 29.97 to pal 25. The video is resampled, and the audio does not need to be touched.

how did you try to frame serve to it ?

[BJ_M]

and what was the source ?

[alsyed]

if it is mpeg2 source, what i usually do is run through dvd2avi, then run the d2v file through vfapi reader codec which creates an avi file to which can be loaded up. Make sure to set the properties though of it inside of vegas to the correct frame size and frame rate.

[BJ_M]

if it is mpeg2 - you could also just load it into vegas

[alsyed]

talking about an elementary mpeg2 vid stream. can't load them directly into vegas or just about any nle. If it is muxed then its fine mostly.

This is some new Info to me,Must try this.Thanks for the tip.

I know you weren't asking me but in case it's of use or interest, if I want to bring a file into Vegas after it's been filtered in Vdub and/or AVIsynth, I frameserve out of VDub, create an .avs file that calls up the signpost file (and adds any AVIsynth filters, if needed). I then open the .avs file in VFAPI Reader and frameserve it to Vegas. If I want to frameserve out of Vegas, I use the debugmode frameserver.

[rbautch]

The original avi is not recognized by Vegas, so I went to Vdub and tried to frameserve using the avs signpost file. Never used VFAPI before, but I suspect that's what I need. If I can figure out why Vegas is not recognizing the avi, that would make my life alot easier. My souce is a Pal Xvid file. Sorry for my late response, just woke up from my New Year's Eve hangover.

BJ_M Said changing the header will work,It did for him, I still cant get it too. heres the link.

I used the AVI FourCC code changer app to change it, but divx and divx3 are not options in the pulldown. Just Div4 and some other "MP" options. I tried manually typing in divx3, but it would only accept 4 characters. Tried changing it to div3 and divx, but still getting the error 'stream attributes cannot be determined' in Vegas. Any suggestions?

[BJ_M]

use this version pf 4CC changer

avic.rar

[canadateck]

use this version pf 4CC changer

avic.rar

Man this is driving me nuts.I cant get it to work. You dont have a file with the header changed so i could rule that out? Because i tried 2 versions of avic.

[canadateck]

Maybe its because of the main concept encoder?

[rbautch]

Thanks, the new version worked! bj_m, you're the man. Found something strange that may help you, Canadateck. When I initially changed the fourcc code, it didn't work, but I found that after closed the fourcc app, it mysteriously worked. So change the code, then quit fourcc, then try it.

Still didnt work.

[rbautch]

Actually it worked on one of my computers, but not the other. The difference was the latest version of the Xvid codec. Maybe give that a try.

[canadateck]

Version 1.0.3? I tried....LOL

[canadateck]

I really dont know what else to try.

[BJ_M]

make sure you dont have xvid installed -- unreg it -- then try ..

i found that when xvid is reg'd -- it doesnt work .. sometimes ..

it seems that if you install divx after xvid it will also work sometimes -- not always (im trying on different systems) -- but not havng xvid at all seems to work better .. i did not try all version of xvid -- some kind of issue with divx / xvid / ffdshow installed it seems (step on each other)

To resample Pal audio in Vegas, do you have to render audio and video together? I'd rather just render the audio as a separate ac3 file, then have to demux and convert afterward.

[BJ_M]

you can do just audio alone

[BJ_M]

in fact - you can only just do audio alone when rendering ac3

[rbautch]

How does Vegas know to resample at 29fps then? Do the project settings do that? Any special render settings?

[canadateck]

Your Vegas Settings would be for NTSC not Pal.

[alsyed]

vegas will not adjust the duration of the video if you select smart resample on the video. Hence your original audio, does not need to be resampled as in other ntsc<->pal conversions.

Remember, if you are doing an ntsc project, every video asset if not ntsc (frame rate, size) will be resampled to fit . It will not be stretched nor condensed. Your audio will stay the same.

[BJ_M]

if you need to shrink or expand audio --- you control drag it to the same lenth as the video ...


what exactly are you trying to do ? I don't quite follow ..

[alsyed]

i'm a bit puzzled to

if now you can open your original avi in vegas, then everythings cool.. just drag the video and audio to your timeline, set your project properties to ntsc, and render out your mpeg2 video, and ac3 audio. No need to sync up or stretch the audio.

To be honest, to stretch would involve a 20% slowdown if going straight to ntsc 29.97.

If your original avi had good a/v synch, then it will have good synch after.

[rbautch]

So when I drag a Pal Avi onto the timeline, I'm ok as long as the project properties are set to NTSC? I'm doing a simple Pal to NTSC conversion, and the audio is synched with the video on the timeline. While I have the attention of Vegas experts, let me also ask if there's a way to do batch encodes...
