Audio waveform height in timline and moving subclips to other folders.

[Jade]

Hello folks,

I made it through unscathed from our work trip to Dayton covering the 1st two rounds of March madness. I've got a couple questions that came out of that trip.

1. How can I increase the size of the timeline's waveform display. We shoot audio on a normal, full level, but the waveform's are barely registering any changes.

2. How can I move/manage groups of subclips. I was unable to move or transfer or copy subclips into desired folders. The source file would move, but the sublips would no show up - remaining in the original folder. (perhaps I'm using incorrect logic here)


Please inform me, JEDIus Masters.

1. You can increase the track height by right clicking on left track header, select Height, and choose 4 or 5. You can also switch the wave forms to Log in the User Settings

2. Sub clips should drag between folders just like normal clips. How are you creating them? Can we see a screenshot of your Bin?

On the first point, I saw numerous Edius users over in Dayton. All of them had waveforms that took the entire height of the track, while not being larger than a 2 or 3 row size. I gave size 4 and 5 a try and the waveforms were still the same ratio.


Here's a screenshot: Clip 'OSU Highlights' being the parent clip.




I'm still experimenting with this one...

Just changed tog 'log' view. I got better height, I'd like the same height scale in linear.

In linear mode the waveform reflects how loud the sound is. If it is maximum volume it fills the display. Does it sound quiet?

Have you tried adjusting the gain (right click on the clip, choose properties, go to the audio tab an look near the bottom)? This will make the clip louder and make the waveform bigger in linear mode. Add too much gain it is distorted.

You can also normalize the clip (right click and choose normalize) and EDIUS will automatically work out the gain up to a certain level - although with the default of -20 I often find waveforms get smaller because my cameras actually record at a level higher than -20db.

Log wave forms will always fill the display but don't reflect how loud a clip is. This is the default setting for EDIUS and probably how the other editors had it set.

Personally I prefer linear. Neither way of displaying sound should affect how it sounds.

Thanks, David. I will give this a shot.

Yes, of to Gain as David mentioned, and you will see the waveform grow larger. Depending on what you are doing, you can also use normalize to get larger waveforms.

Gain is not the same as audio waveform height scaling. One doesn't want to amplify the audio signal in the video, we just want to scale it so we can still see the detail when the audio is quiet.

We need a zoom y axis amplitude control.

Yes thats true - since years!
But what should we do if we don't get it from the developers ??
We can use some workarounds - raising the gain is one of them; nothing else.

Simple as that: don't buy their software/upgrades any more!

Rooooooooooh.

Glad to read that I am not alone with this problem - but I never had it, before the NORMALIZE function was integrated. I use -18dB as a reference level which should be correct for digital, but then the audio - which was correctly recorded with my camera + external Sennheiser micro - is so small, I can hardly see - and hear - it.

At present I have to raise the gain by 10dB for every clip I put on the timeline - I don't think this is normal. I thought NORMALIZE was to adjust all audio clips, after the whole editing was made.

What do you suggest: Shall I set the reference level to 0dB or 8dB? This would probably solve it, but does not appear logical to me.
