Plus, it will NOT overwrite Vegas 4 so, if you do happen to have any problems, you can still use Vegas 4.

Adi Head June 19th, 2004 10:15 AM

doing it in sound forge or cubase can be done easily. i know how to do that. i'm just a bit surprised there is no simple way to do it in vegas. when i jog through the shot quickly, i DO hear the sound as i would have liked to have it. oh well, i'll open it up in cubase and do it.

thanks edward

Edward Troxel June 19th, 2004 10:20 AM

Vegas is kind of unique in the NLE world because of it's strong audio capabilities. However, it was designed more as an audio MIXER than editor. You still need Sound Forge to do some things even though most things can be done directly in Vegas.

can i re-capture media clips?
 
is it possible to re-capture a project's media clips?
the situation is like this: i'm working on a project. i've already captured all the video clips i need and have them stored on my hard drive. but half-way through editing, i realized that accidently i captured the clips with audio sample rate set at 16 bit/sec instead of 24. if i choose to, can i erase the media clips i have saved at the moment, recapture the media clips with the audio sampling rate set at the preferred 24 bits/sec, give the clips the same names they had before, open vegas, open the project i had been working on and continue editing?

Graham Bernard June 20th, 2004 01:22 AM

Hiyah Adi!

Yes . . I had a project totally but totally go tits up on me .. one week before the launch!

Okay, as long as you have the VEG file you can "recapture" media. I would experiment with a "draft" project, a type of alternative to the original VEG - yeah?

Study the online help and look for "recapture" media. It would be too complex to describe it here, but it is fairly painless. Once you are into recapture MAKE sure you recpature at the corect audio depth. I haven't done EXACTLY what you're trying to attempt .. but I can't see at the moment what the problems would be .. As I say do this with an experimental VEG first - yeah? oh yes take notes of what you did ..

Hope this helps,

Grazie

Edward Troxel June 20th, 2004 05:34 AM

Umm.... exactly HOW did you capture? If you capture via firewire, it's like copying a file from the camera to the hard drive. The audio will be identical to what's on the tape. If you recapture via firewire, it will come in exactly the same way.

Adi Head June 20th, 2004 10:02 AM

i capture from my mini DV via firewire. i figured there wouldn't be a problem with recapturing what i have recorded on my mini DV tapes, because, as you say, the files will be identical. i just wanted to make absolutely sure before i go ahead and erase all that i have already captured from my hard drive (since i am more than halfway done editing the project). thanks!

Peter Jefferson June 20th, 2004 11:18 AM

dude no need, dvd and dv only go up to 16 bit anyway..

the only real use for 24bit is dvd audio.. and i wouldnt be using a DV cam for that anyways..

Adi Head June 20th, 2004 02:12 PM

"... dvd and dv only go up to 16 bit anyway"

i must be misunderstanding something. i was sure that dvd audio is 24 bit/sec like audio cd's. i admit that i've always felt uncertain when it comes to technical details. i barely know what it means. but i was completely convinced that the audio on dvd's was 24 bit/sec. wierd.

John Cline June 20th, 2004 04:52 PM

Yes, you have a few things confused. There is no such thing as 24 bits per second.

There are two main things that describe the format of digital audio, the first is "sample rate" this is how many individual samples of audio are taken every second. In the case of audio CD's, this is 44,100 sample per second (44.1k), for the audio portion of DV video, it is normally 48,000 sample per second (48k). (Although, it can also be 32k.) Sample rate affects frequency response.

The second part of digital audio is the "bit depth", this determines how precisely the audio file can describe changes in the amplitude, or volume. In the case of both audio CD's and DV video, this is 16 bits. 16bit resolution can describe 65,535 different levels of amplitude. (Actually, +/- 32,767), from silence to full volume. 24bit audio can describe 16,700,000 discrete points of amplitude resolution. Obviously, a much higher resolution than 16bit audio. However, the audio which is captured from a DV camcorder via Firewire is 16bits and normally at a 48k sample rate. Depending on how you have your camcorder set, the audio can also be 32k 12bit, but there is normally no point in doing that, it should always be set to 48k 16bit.

Finally, yes, DVD's can support up to 24bit audio and normally at a sample rate of 96k, but your DV footage is 48k, 16bit, so just use that.

John.

Adi Head June 21st, 2004 12:22 AM

john, thanks! that cleared it up for me.

Mark A. Foley June 21st, 2004 07:04 AM

Although not every slo-mo sequence is the same/looks the same, I have found at times when the softening effect is produced as Edward mentions, I copy the clip to a new track...add the Convolution Kernel (with the sharpen preset) and set the opacity of the track at 30%.

Peter Jefferson June 21st, 2004 09:24 AM

Vegas 4 is faster than 5
 
when vegas 5 can render as fast as V4, thats when im gonna upgrade...

i started rendering the same project on V5.. tel me 28hrs at 10%

I cancel and throw it back to v4, renders at 17 hours...

on top of that, project loading times are significalty longer (were talkig 14 hours worth of raws being loaded into the Media Pool)

right now, im only using v5 to do stuff i cant do with V4...

anyone else figure this??

Edward Troxel June 21st, 2004 09:35 AM

Would need more details to determine why 5 might be that much slower. Were you using a Parent/Child relationship at some point in the project? If yes, that's probably the reason why.

Also, remember that the time is an estimate. The actual time may be much less than the estimate at 10% depending on the details of the project.

Peter Jefferson June 21st, 2004 11:27 AM

all identical, every frame had to be redrawn..

basically i did the original render.. took 21 hours..
threw the project into v5, took 28 hours

now, im running th same render using a square pixel aspect, and its running 17hours... v4

all identical, no parent child, 3 video tracks 8 audio tracks..

Dave Largent June 21st, 2004 04:10 PM

Mark, what effect does this have?

Mark Richman June 21st, 2004 06:53 PM

PhotoStory2 by Microsoft
 
Has anyone found any software other than MS that does automatic pans and zooms like PhotoStory 2?

Microsoft has a good solution however it only renders to .wmv files. (It really reduces the workload for photo montages
however rendering is very long.)

I have been looking and I haven't found a solution that does the automatic pans and zooms.

Any help would be appreciated.

Mark

I can do this in Vegas but takes a lot more time

Take a look at the PBS Wizard in Neon. http://www.vegastrainingandtools.com

Mark A. Foley June 22nd, 2004 05:17 AM

I have found adding a sharpen preset with the convolution kernel restores some of the "softening" created by the slo-mo sequence. Dropping the opacity of the track takes some of the bite of the sharpening effect...alll of the settings can/needs to be tweaked for each slo-mo created....

Rob Easler June 22nd, 2004 11:08 AM

Mark, instead of the filter you use I just apply the sharpness filter to the slow-mo'ed clip at a level of about 400. It saves a step or two. I compared a clip with the sharpness filter and the convolution/opacity process you are using and I can't really distinguish a significant difference so it's worth a try to save yourself a step or two.

Mark A. Foley June 22nd, 2004 11:15 AM

thanks rob....as it would probably save on render time as opacity changes seem to ramp up the render time. If I ever get a break in my editing I may test using just the sharpen filter over the convolution kernel....

Rendering an HD 5.1 mpeg file in Vegas
 
Hi, i'm editing an HD project with footage from the JVC HD10 Camera, I can edit and export just fine but only in stereo.
Is it possible to render an HD mpeg file with 5.1 Surround Sound and then export it back to the camera?
Thanks!

Yi Fong Yu June 23rd, 2004 11:43 AM

vegas's 5.1 is 2D only. can it do 3D like master&command?
 
if you have master&command you know that sometimes the footsteps sounds like they are coming from above. can that be achieved with vegas5?

Rob Lohman June 23rd, 2004 11:43 AM

No, that is not possible. Your camera does not support 5.1
sound or AC3. But you can definitely export an AC3 audio track
for use in DVD authoring.

Nuno Madeira Rodrigues June 23rd, 2004 11:56 AM

<<<-- Originally posted by Rob Lohman : No, that is not possible. Your camera does not support 5.1

How do I export an AC3 Audio track??

Thanks again!

Peter Sieben June 23rd, 2004 11:59 AM

What you can do is render an 5.1 AC3 audio track. Convert that with some freeware tool to a Dolby Prologic Surround WAV file (I use Azid for that, which can create a 24 bit WAV file). I import this WAV file in the timeline and mute all the other audiotracks and render the video + audio to an AVI file which can be transfered back to the camcorder tape. It's not 5.1 DD, but it's an alternative you could consider.

Peter Sieben

Rob Lohman June 23rd, 2004 12:26 PM

File -> Render As -> Save As Type = Dolby Digital-AC3?

Harris Ueng June 23rd, 2004 01:06 PM

Hello Yi,

There isn't an NLE out there right now (that I know of) that can do automatic mixing (like Vegas) for a 10.2 system with height channel, esp. since there are no commercial theaters out there that incorporate a height channel, AFIK.

As far as "Master & Commander", the 'footsteps coming from above' effect may just be your brain tying in visual cues of what's going on onscreen to sfx and foley that is coming from the audio tracks. In a 5.1 system, there is no height channel.

Glenn Chan June 23rd, 2004 08:05 PM

If you use a parametric filter with a deep notch (9dBish) in the high frequency range (7k to 9k) and move it around your brain will perceive some height. You might want to play around with this on some white noise.

This effect works on headphones I believe (and not speakers). The folds in your ear are responsible for this effect- they attenuate those high frequencies due to interference. 7k corresponds to sound on the same level to you, and 9k to sound above you IIRC.

My memory is a bit hazy on this- perhaps the folks in the audio forum will know more.

copying track envelopes. is it possible?
 
hi.

i edited a wedding ceremony using vegas 4 (still haven't updated). i found it easier to devide my work between two seperate veg files, intending to eventually cut and paste one to the other and make them into one complete project.

i've finished editing and am at that stage where i want to cut and paste. when doing so, i found out that cutting and pasting events from one track to another does not include inserted track envelopes. is there no way to copy envelopes from a track on one veg file to a different track on a different veg file?

Adi Head June 24th, 2004 12:54 PM

I GOT IT! sorry for bugging you. i figured it out by myself. completely forgot about the envelope editing tool!! thanks anyway.

24p DVX100 footage in Vegas
 
Hey!
I've got a DVX100 (not mine), a stack of tapes shot in 24p, and Vegas 4.0 in front of me.

My project will be outputed to NTSC VHS, it will also incorporate 60i footage shot on Canon XL1 cameras.

I'm not really familliar at all with editing in 24p. What do I need to know about caturing it, editing it, and mixing it with 60i on the same timeline?

Thanks!

Michael Wisniewski June 24th, 2004 05:34 PM

See the bottom of page 9: Sony - 24p camcorder support (pdf).

Dylan Couper June 24th, 2004 10:21 PM

My web browsing computer is half messed up right now, and it won't let me download anything, including .PDFs Could you direct me towards another site?

AC3dll plugin errors since installing DVDA2
 
okies heres a wierd one.. in the past, i could easily set any level on any track with n problems..
when encoding to ac3 within vegas, i would set up my metadata etc etc all good...

now..
when i import this into DVD2, and i can see the timeline of audio and video, there are onvious white noise glitches.. these in turn crash DVDA2...

for some reason the encoder is shitting itself and recording noise...
then the ac3 plugin tries to open this file, it completely dies..

Now ive never had issues with noise, or level limits, however im now back to using dvda1 and this is my 4th ac3 render which seems to be unaffected.. mind u ive had to drop levels considerably, but since i installed dvda2, thats when the problems started..

On top of that it takes FOREVER to load up a project..

heres hoping for an update..

Edward Troxel June 25th, 2004 07:39 AM

I find it simpler to just render both sections and start a "final" project using the rendered segments.
