Key frames in audio

Greg123 wrote on 2/22/2024, 5:36 PM

for Movie Studio 2022 Suite,

I cannot find key frames in audio editing where I could - say - lower the volume in selected - by 2 key frames - area on a timeline Another disappointment comparing to Studio 2016 where it was easy to find and apply ! The only reason I changed to Studio 2022 Suite is that it can handle 4k video...( Studio 2016 couldn't) ,other than that it's much more complicated at NOT user friendly.😳😧

Is anybody who knows how to do it??

thank you very much☺️

It's in the Audio effects section.

Place your cursor on the timeline where you want to change a level or control position or amount of effect with the relevant control and add a key frame.

Or you can record live movements of the mixer in play if you have the Auto button active. Hold down the left mouse button while on the appropriate track slider or rotary control. You can over-write the position if need be on any subsequent pass.

Curves can also be hand drawn using the curve tool.

Do be careful though as all could be present at once on the same track if prior curve sets of instructions are not reset.

Yes, with more choice can come more complexity but one work flow may be preferred over another by any individual.

Hi,

See my last post.

I suggest that you watch my tutorials on Everything Audio - both parts - in which I cover volume curves.

Movie Studio has extensive audio features. What Ray has shown you are 2 of them.

Vegas Movie Studio only allowed track level volume curves (envelopes) with keyframes. Magix Movie Studio has object (event) level volume curves plus track level volume curves. The object level volume curve is directly tied to the Audio Effects/General/Volume slider and keyframes. If you turn on the Volume Curve by right-clicking on the audio object, the keyframe area in the Effects window will show up.

I am going to assume that you are putting Video and Audio on separate tracks. If not, do so by changing the parameter in Program Settings. For any video objects already on the timeline with both AV on one track, use Ctrl+H.

Here is a listing of various ways to adjust the volume in MMS:

  1. The middle handle of the audio object adjusts the volume of the object
  2. The left and right handles do fades
  3. Right-click the audio object, Set volume to raise or lower the above middle handle by preset values
  4. Right-click the audio object, Volume curve allows you to put points (keyframes) on the curve, either directly or under Audio Effects/General/Volume slider and keyframes
  5. Right-click the audio object or an empty area of a track, Display track curves turns on the track volume and pan curves. You can manually place keyframes and drag them up and down or use Automation in the Mixer as indicated by Ray
  6. Right click on an audio object, Decrease Volume - for ducking/damping other tracks over the duration of the selected audio object. This puts points on the track curve, so the object should not be moved somewhere else along the timeline, in other words, to be done after all editing affecting object locations on the timeline
  7. In the Mixer, turn on automation and adjust the volume slider during playback. This creates points on the track curve
  8. In the Mixer - track slider to adjust overall volume of the track if Automation is turned off
  9. In the Mixer - Master strip slider to adjust overall volume at the end

You may also want to consider compression, which can lower or compress audio peaks.

I found other way to do it, without key frames ! I simply cut audio path on the timeline in couple places and adjusted volume in each part...works (almost) like key frames...

browj2 wrote on 2/23/2024, 11:56 AM

@Greg123

Hi,

Yes, that is one way.

Here is what I usually do. The first modification was done by clicking on the curve and dragging the points down. But, to be faster, in the second case where you see a lot of points, I go into Curve mode and quickly draw over the audio object where needed. That way I can go along the timeline and draw wherever I see spikes. The volume curve gets automatically turned on when you draw on an audio object, so one must not forget to go back to normal mouse mode when done.

Hi

. . . . I simply cut audio path on the timeline in couple places and adjusted volume in each part . . .

As @browj2 commented that is a different method, however IMHO, it is potentially fraught with issues when you start moving objects around.

I use the right-click audio and select Volume Curve option to turn the curve on and, when the mouse pointer changes to a black arrow head when hovering over the green curve, double left click to add nodes.

The nodes can then be dragged in the appropriate directions to control the start/end positions and decrease/increase in audio levels, with practice and a visible waveform it is quick and easy.

It has the added advantage that the audio file is all in one piece, which makes moving the audio easy.

Thank you John EB, I found it, used it, it's almost as easy as in Studio 2016 now !. ☺️

The way John CB explained it is like reading a furniture assembly instruction ( American and Chinese), where even someone with handyman skills has no idea what they were writing about.😁 😳

Hi,

The way John CB explained it is like reading a furniture assembly instruction ( American and Chinese), where even someone with handyman skills has no idea what they were writing about.

I didn't really explain it. but I did give you an image. I assumed incorrectly that the rest would be intuitive.

In the numbered part, I gave you a listing of all of the different ways that audio volume can be modified in the program. Point 4 was about getting the object volume curve with a quick indication as to how to use it.

Even in my tutorials on Everything Audio, which you should still watch, I only cover things quickly or the videos would be 2 hours long each. The intention is to get an overview as to what is available, not details on how to user everything.

It seems that you need details. A video would be best, but here is the gist of it which I will eventually turn into a video tutorial.

To complement what John EB and Ray gave you, once you turn on the volume curve, you click on the green line when the hand cursor changes to an arrow to place a point. If the mouse is not over the green line, you won't get the hand cursor. Then you can drag the point up/down left/right but not over or past any other existing point. Note the arrow cursor circled in the image below.

Another way to do this without having to turn on the Volume Curve is to switch to Curve mode as Ray and I pointed out. This is faster if you have a lot of adjustments to do.

In the image below, right-click on the button to get the menu and select Curve or use shortcut 9 (from your keyboard, not the numbers pad). You are now in drawing mode for audio.

On any audio object, just start drawing where you want to adjust the curve by holding down the left mouse button. If you keep holding down the mouse button and move, you'll get a lot of point. To get fewer points, just hold down the mouse button and drag a tiny bit then release. It takes a bit of practice. There is no need to select the object (in fact, you cannot select an object when in Curve mode) and no need to turn on the volume curve as it will automatically turn on.

Points will be placed as you drag the cursor along and up and down. This is faster than placing points manually. Shortcut 6 to get out of Curve mode, and back to normal mouse mode. Now you can modify the points - select and drag, select and delete, or click on line to add points.

You can stop there, but you should learn how this all works together with the Audio Effects because you can fine-tune there or create and modify there.

In Effects, Audio Effects, General, look at the Volume slider and the keyframe area (that is at the bottom of the Effects window). In the image below, I had to zoom in on the keyframe area to see individual points because I created too many points using the Curve mode.

In the image above, I have circled a point on the curve in the timeline. It is the same point that is circled in the keyframe area in the Audio Effect for Volume, and the value, 54, is shown at the right of the Volume slider. Follow the arrows.

You can adjust the volume of that point by dragging it in the timeline curve or by moving the Volume Slider, or by typing a value into the box at the right of the Volume slider. You can move the point along the timeline by dragging it in the timeline curve or by dragging the point in the keyframe area, however, you cannot drag it over or past another point. You can add points directly in the keyframe area. If you don't know anything about the keyframe area, I have a tutorial that shows how to use this in detail.

Note that default volume shown at the right of the Volume Slider is 100 (0 means volume off). This corresponds to points on the curve at the top of the object. You cannot use these points to increase the volume above the original volume. To raise the overall volume of the object, you have to use the middle handle of the object as shown below. I have raised the overall object volume by 5.0 dB. This is a relative adjustment, not absolute. If you raise the volume too much, you'll get clipping.

Here is another difference from Vegas that is related to the above. Vegas has switch for normalization. I have never been able to figure out how that works. Normalize is not a switch, it's a volume adjustment. In MMS, if you normalize the object audio (right-click on the audio object, Normalize), and if the maximum or loudest part is less than 0 dBfs, then the slider in the above image will rise above 0 (the volume line, not curve, is in the middle of the object). This way you know by how much the volume has been raised due to normalization and you should not exceed this level or you will get clipping. When I normalize, I always drag the object volume slider down by at least 1 dB. If there is audio on any other track at that point, then I'll probably getting clipping and I don't want clipping.

There is a lot to learn.
