Macro Tutorial and Example
Click the image to download the macro that you see
Simply extract the file and place it in the following directory on your Broadcast Pix Computer Workstation:
This is an example of an Alpha Wipe (a video transition between twoexternal or internal sources). It uses the file "02 Light Swipe-A.bpa"to transition between what is currently set to your Program source andwhat is currently set to your Preview source.
This Macro is ready for use as soon as you put it in yourmemories folder and then start your Broadcast Pix Switcher Application. Simply go to "Window>Float>Macros" or press "CTRL + M"simultaneously when the software loads. This will bring up your FluentMacros window. Click the "Macro Editor" button and select "Open" andbrowse to the file in your memories folder.
Now by pressing the large "Play" button at the bottom of the screen,you will see this alpha wipe in action! If you do not see the LightSwipe between the images, then the sample clip, "02 Light Swipe-A.bpa"may have been removed from your system.
You can re-download that clip here.
Understanding the Sample Fluent Macro
Breaking it down step by step
Each line in the macro is referred to as a "Step." Each Step performsone "Action" within the Broadcast Pix software.
You can view the StepNumber by holding your mouse over any line of a Macro in the Editorwindow. This macro contains four steps right at the beginning that wecall "Preparation Steps."
This can also be accomplished by adding a "Pause" from"Insert Step>Macro Utilities>Pause" and changing the Hold Timefrom "0" (wait for user input) to "16" (Times Pause), and then makingthe Step Three Hold Time "0."
Here's where the real meat of the Fluent Macro begins.
And that's all it takes to create a quick, reliable alpha wipe!
So far we have discussed the "Hold" and "Action" columns. Let'stake a look at some of the rest of the Macro Editor window.
The firstcolumn is labeled as "Run Time." This is the calculated time yourentire macro will take to run, not including pauses. You do not needto ever change anything in this column, it will change whenever youchange the Hold Time on any step.
There is also a "Notes" column. This column is very usefel tohelp you serarate your actions visually to remind yourself of what eachstep does. Also, in the Macro Player Window, any text in the Notescolumn will show up as the Macro is playing.
Customizing the Sample Fluent Macro
Making Fluent Macros work for you
Now let's try adapting this macro a bit. First thing we will do isclick the "Save As" button at the top of the Macro Editor. When theSave As window opens, change the Macro name to 998 Alpha Wipe 2. Nowwe can make changes to this while keeping the original in workingcondition.
Let's say we have TWO alpha wipe animations. We want to use oneanimation to GO to a replay, for example, and we want to use adifferent animation to RETURN from that replay. First of all, we willneed a second alpha wipe. Check your Sample Clips folder, If you see afile there called: "Lens Flare Swipe.bpa." If you do not see it, youcan download it here. Place that file also in your"D:\Clips\Sample Clips" folder.
Now let's add a new step.
Just as an experiment, go ahead and play your Macro now. You probably won't see much of a difference, except that when the Macroreaches the Pause step, The Play button will blink (on the ControlPanel, the button will remain lit Red during a pause). Simply press the Play button again to continue the Macro, which in this case will simply end it because there is nothing after the pause.
Let's try adding some time to this pause step.
This direct typing can be done on the "Hold" and "Note" columns directly in the Steps without having to go to the Edit Window.
Now play the macro again. This time you will see the Playbutton flash briefly, but then stop because the Pause only paused for15 frames, then continued the Macro Playback and ended.
Now let's look at another way to insert a pause.
The next step that we want to see visually is the new animationcoming BACK from our replay. So we need to change our animation inClips 1.
You will notice than when you press the "Record Steps" button the firstthing it does is insert a pause for you! This serves two purposes. Itallows a visual note as to where you began your step recording, as wellas adding a pause because everything that happens after that pause willhappen instantly. Using the Record Steps feature instead of the normalRecord feature will record all the moves you make at a hold time of 0instead of recording the time between button pushes.
Don't see the clip in your PixPad? No problem with Fluent Macros! Select any clip in your store and then press Stop record. You will see something like the image below:
This might come in handy to get some of these animations away from theoperator so you don't accidentally select them during a production.
Now we are going to record the Wipe the "normal" way so we can getthe timing close. There are three steps to do this, Add Direct Key 3,Perform Cut, and Remove Direct Key 3. Now that we have our newanimation in Clips 1, it is the exact same steps to use this one as itwas to use the one above.
We now have our macro almost entirely complete. The only thing left isto adjust our Hold times on these last three steps because it isdifficult to get the timing correct live.
This is a great feature if you're changing a bunch of values at once, simplychange your hold time, then using the up or down arrow keys, change thevalues on the other steps above or below as needed.
And with that, we have a completed two-step Alpha Wipe with a differentanimation for GOING to a source and RETURNING from a source. Play itthrough, adjust the times on the Perform Cut Steps and the RemoveDirect Key 3 steps to see what changes.
If you want to further customize the Macro, you can define a specificsource for it to go to each time (set Preview Source before the PerformCut step), or select a Clip at the very end that wil will be likely toneeded next so it is already loaded in the Clip Store (and you won'taccidentally play the Alpha Animation again later). Maybe you want tomake sure at the top of the macro that more keys are removed, or theyare removed when the macro cuts using the Next Transition layers. Maybe you want a certain key to come back on the air each time afterthe second wipe (like a scoreboard or a logo or date).
The easiest way to customize your own Alpha Wipe Macro is to changeyour the clip(s) into ones with your logo on it. As we've learned,that is as simple as clicking a browse button and changing which filethe Macro is looking for! For situations where you don't know too farin advance who might be sponsoring your replay, for example, you canjust open the macro, change which sponsor wipe you want to use and hitplay! One button for your TD and countless possibilities at theirfingertip!
There is a lot you can do with Fluent Macros, this is just a quick example.
