First, Katyusha software installation preparation
The newer version of Katyusha software is currently version 8.6 of camtasia. This version requires Windows 7 (or above) operating system support, but also requires a higher computer configuration (CPU is best in i5 or above).
If your computer is using the Windows XP operating system, then it is recommended that you install the camtasia 7.x version. This version has lower requirements for computer configuration, and the Pentium processor is basically sufficient.
The two versions operate exactly the same. However, there will be some differences in the function section. If you want to do better, only the version of camtasia 8.6 can be fully implemented.
Once you have installed the camtasia software, simply click on the camtasia icon on your desktop to launch the Katyusha software. The startup interface is as shown below (the interface captured in this article is camtasia 8.6 version):
Second, Katyusha rookie three stepsThe Katyusha rookie only needs to learn three operations to meet the basic recording requirements of the micro-course. We call it the "Katyusha rookie trilogy."
1.1 One of the three steps of the rookie: recordingThe Katyusha recording screen can be divided into 4 small steps, as follows:
1) Start the screen recording programIn the above Katyusha interface, click the “Record Screen” red button in the upper left corner of the window to pop up a new window in the lower right corner of the screen (as shown below). This program has only one function: the recording screen.
2) Check both options
In the above window, you first need to check and set the "Selection Area" and "Record Input" sections.
In the "Select a region" section, if we need to record a full screen of the computer (such as recording PPT playback), select the "Full Screen" option; if we only need to record a part of the computer screen, click the small arrow next to the "Customize" button And select "Select Area Recording" (as shown below) in the pop-up menu, you can use the mouse to arbitrarily select the screen recording area of any size.
In the “Record Input” section, you need to set the sound to “Audio On” and pay special attention: when there is a sound around, there should be a small green bar in the volume control bar on the right side of “Audio On”. The sound size is beating (as shown below). Only in this way, the narration dubbing when we record the screen can be recorded.
3) Start recordingAfter the above two steps are completed, we can open the program window that needs to be recorded (for example: if we want to record PPT playback, we need to play the PPT first), then click the red "REC" button.
Then, the “Countdown” prompt shown above will appear on the screen. Please note the red "F10" in the picture above - this is the shortcut to stop Katyusha recording.
After the countdown is over, the screen is as usual, but Katyusha has been faithfully recording all the pictures on the screen and all the sounds coming from the microphone. At this point, we only need to operate on the computer and explain the voice.
4) Save the screen file
When we finish the recording operation, press the “F10” key on the keyboard to stop the recording operation. At this point, Katyusha will display a "Preview" window (as shown below).
Normally, we don't need to carefully watch the "preview" content, just click the "delete" or "save and edit" button in the lower right corner of the above image.
If we click the "Save and Edit" button, Katyusha will save the screen file and automatically place it in the main interface, as shown below:
1.2 rookie three-step two: cut
No matter what method we use to record, we can't avoid a problem: we can't guarantee that the recorded picture, or the sound of the explanation, will not cause any errors or small slips. As a kind of "short and fine" teaching video, it is best not to make these mistakes in the micro-class, in order to create a good learning experience for the learner.
Before learning how to deal with these errors, we need to understand one of the most basic operations in Katyusha: how to control the playback of video.
In the above image, click the “Play” button in the middle of the right side, and the video at the top right will start playing. At the same time, the "time cursor" in the above image will also move on the timeline - in fact, the "time cursor" indicates the time of the current picture. Therefore, when we manually drag the time cursor and change its position on the timeline, the video image on the upper right will also change.
After understanding this operation, let's take a look at how to cut out the wrong part.
First, by playing the video, we can find the approximate location of the wrong part (area). Normally, we place the time cursor on the left or right edge of the wrong part (area).
Secondly, in the above figure we can observe that the time cursor has two ears. Simply drag the left and right ears of the time cursor to select a bright blue area (as shown below).
We can constantly adjust the position of the left and right ears by repeatedly playing and auditioning until it is confirmed that the bright blue area needs to be cut off. Then click on the "Scissors" button on the timeline to cut out the bright blue areas.
Sometimes, the area that needs to be cut off is small (time is short), such as: small mouth errors. In this case, it is difficult to make precise choices on the timeline. At this point, we need to "zoom in" the timeline by dragging the "zoom slider" above the timeline to the right (as shown by the arrow below).
Please note: The above two images are actually the same selected range, except that the timeline units are different.
In addition, when we have done the above, it is recommended to place the timeline zoom slider in the middle position to take both the position and the range selection.
1.3 The Three Steps of the Rookie: Saving and PublishingWhen we cut all the errors in the second step above, we can publish the screen file as a video format. But before we release, we should first "save the project." This is because we have just cut the screen file in Katyusha and it will not be saved in the original screen file. If you need to further edit the video in the future, you need to save the project first.
To save the project, click on the "File" menu, then click on the "Save Project" submenu and enter the file name. After the save is successful, a green icon of the Katyusha file will appear in the save directory. This is the project file - in contrast, the Katyusha screen file is displayed as a red icon.
