Audio Conflict with Pinnacle

[merrick61]

There are some filters in Pinnacle Studio 11 which I like to use in Edius.
In order to open a Canopus AVI file in Pinnacle, you first must use procoder express to convert it to a Microsoft DVAVI. Once in Pinnacle, you can add a filter such as a nice lens flare. The issue is when playing back in Edius, all audio mutes out GOING TO FIREWIRE only. Even if there's audio on an audio track it mutes out. There is waveform data there and the audio plays fine through the computer speakers, but not on firewire. I tried changing the project settings from 44 to 48 but that doesn't help. You can hear the audio through firewire while scrubbing oddly enough. I am almost certain this has to do with the KHZ setting but can't figure out how to play it.

Any ideas?
Thank you!

audio should be 48k from start to finish

maybe pinnacle converted it to 32k in which case it won't match 44 or 48k

however, use 48k all the way

[merrick61]

Actually i checked pinnacle and it kept it 44K--
Whats weird is i got it to work by changing the speed of the clip.
I figured since I could hear the audio by scrubbing, what if the clip speed were changed? Changing it by even less than 1%, suddenly brings the audio on the timeline back to life. What I coulddnt figure out is even if the audio on the pinnacle clip didnt match why were all the audio tracks muting out?
Go figure..
Sometimes DV audio can be very picky.
thanks for your input

There are two allowable audio standards for DV avi, 48khz 16bit, 32khz 12bit,
any other audio standard needs to be converted to be used correctly and match project settings which should be either of the above depending on the setting of the original video.

[merrick61]

I understand what you are saying but question:
Why is it then that under project settings you can either chose 44 or 48? Iif the only acceptable standard is 48)
And Pinnacle only uses 44 for DV ...you can't even select anything else.
Even when both Pinnacle and Edius match at 44...the audio does not work.

[antonsvideo]

why not leave the original audio in Edius and simply place the modified pinnacle video on an empty V only track above the existing

the worldwide standard for pro video is 48k

when you buy a DV camera, you can preset it to 32 or 48 (44 is never offered)

maybe you did not use a DV preset in pinnacle or pinnacle is faulty?

[merrick61]

Its weird Anton
I checked to see how Pinnacle is creating the file. Looks like it is 48KHZ. My project is also at 48. the audio cuts out only when the effect is happening (that Pinnacle creates). So if its a transition, the audio will drop out near and around the transition point. If its a filter like a lens flare or shake effect, it will cut out during the filter. And the audio on the whole timeline goes dead too. Placing it on a V only track does not help. All the audio dies.
The audio is there , though because there's a waveform and you can hear it during scrubbing. Only during regular playback DURING THE ACTUAL EFFECT does it cut out. And the project, as i stated is set to 48khz across the board.
And this is only a firewire problem. You can hear the audio through the computer but the DV out is at issue. So if you were creating a DVD theoretically it would be ok but mastering to DV tape, would be an issue.

I wonder why changing the speed of the clip rectifies the problem. Its not ideal but so far the only solution that actually works.

try this quickly

set in and out point on timeline

export to new wav file (does not take long at all)

place the wav file on an empty A track below and turn off all audio an all other tracks

does it work now?

[merrick61]

Thanks for your help.
But I did try that already. I even loaded up an old version of Sound Forge XP
to see if there were any other audio formats I could export to--but no. nothing worked.
In Pinnacle, (where the audio obviously does work) I outputted to DV tape, then re-captured in Edius with the same problem.
Bizzare?
I think so

[antonsvideo]

so the problem is in pinnacle

like I said earlier, leave the audio in Edius and place the pinnacle video on a V only track, guaranteed results

[merrick61]

placing the pinnacle video on a v only track yields the same unfortunate result-Muting of all audio.

You are right the problem is in pinnacle and I think the clue is the issue is happening while the effect is occuring. Pinnacle must do some strange processing while making the effect which is changing the audio characteristics.

I think that Anton was saying to leave the audio in Edius and work with the video only in Pinnacle.

This is easy to do... take the entire timeline to a file like you are doing now.

Start a new sequence.

Map the audio to A1 and place the new made file on V1. You will see that the audio will split off into A1.

Now, Take the new file into pinnacle and do what is needed to it.

Create the new file with the effects you wanted.

Bring that file into your EDIUS project.

Now, In the sequence with the audio split off LOCK A1.

Now overwrite the video with the new one you created in Pinnacle.

The video will be replaced but the audio will not.

Yo can do one more step by highlighting bth the audio and video and then right clicking on them and choose GROUP.

Now they are linked :)
