Create a video tutorial for Camtasia Studio-go

Step 1: Record
Use the recorder Recoder in the Camtasia Studio suite in the Screen mode
Enable recording, mouse sound, mouse click prompt, and other options as needed. Generally, I only use recordings.
The recording quality can be set to 22 khz and 16-Bit Single Channel. Higher quality is meaningless.
Enable the microphone gain option. The microphone volume is about 70%, and the recording volume is about 70%.
Do not increase the two in a loud fashion; otherwise, violence and ultrasound may easily occur, which outweighs the loss.
Set the recording shortcut key. I set it to F9 (recording/pause) and F10 (end ). Be sure not to conflict with the software you want to demonstrate. If necessary, add ALT and other secondary keys.
Enable Pause before recode in the options, so that the recording will not be recorded immediately after the recording range is specified.
Specify 15 frames per second in the video option, set the encoder to TCSS, and select AVI as the output format.
In addition, close all background running projects, such as various firewalls and communication software. To record the screen, you can also hide the start taskbar.

Press F9 and prompt to select the screen (in case of dual-display). After confirmation, the recorder is paused.
Move the mouse to the starting position. The microphone is about 20 to the mouth ~ 30 cm
Remember not to align with the mouth. Otherwise, it is easy to record the noisy sound. It should be located at the first 45 degrees on the side.
Press F9 again to start recording, move the mouse, and explain.
During the recording process, you can press F9 to pause and take a break or adjust your mind. Press F10 to End recording and save the file

During the recording process, you may be able to say something wrong or perform a wrong mouse operation. You do not have to rush to cancel the recording.
You can continue recording and make significant changes to the screen, such as displaying the desktop for several seconds.
This leaves a visual reference for later editing. You can also view the time displayed by the recorder.
It is best to have a dual-display and place the recorder window in another monitor to conveniently view the recording status.

Step 2: Noise Reduction
Unless your microphone is several thousand yuan or tens of thousands of yuan, and your audio device is external.
Otherwise, the recorded noise will be obvious, and the current sound will be affected even if the surrounding area is kept quiet.
The most obvious is the low buzz.

Enable Adobe Audition and open the recorded AVI file. The sound track is automatically displayed.
Double-click the sound track to enter the editing status. Select Effects_Restoration_Noise functions]
In the displayed dialog box, click Select Entire File, and then click Capture Profile"
After the sampling process ends, adjust the value in Noise operation Level. I usually select 1.
Press Preview to hear the effect after processing, and click "Bypass" to hear the original sound. Confirm after satisfaction
Choose "ACM Waveform (*. wav)" to save the audio file )",
Click "Options" and select the PCM format, 22 kHz, and 16-bit single voice.

In addition, to adjust the volume, you can use [Effects_Amplitude_Amplify]
This method can also be used to eliminate violent sounds, such as desktop percussion.
The method is to select the violent sound range in the audio track and then reduce its volume as much as possible.

If you need to retain the required explanatory sound in the same position, you can use [Effects_filters_Graphic Equalizer]
In general, the frequency of human voice is different from that of various percussion sounds. At this time, you can try to decrease the value of each frequency to eliminate violent sounds.

Note: When listening, you should increase the computer volume. Otherwise, some small noises may not be heard.

Step 3: Cut
Enable editor Studio in Camtasia Studio and input AVI and WAV Files,
Add the AVI file to the track
Select the length of all tracks, and choose Edit_Audio_Replace With Silence from the menu. Then AVI will be silent.
Then add the WAV file to the track. The length should be the same as that of AVI.

For full-screen recording, the recording resolution is usually 1024x768.
However, the output video must be reduced to 640x480 to adapt to most viewers.
This is equivalent to reducing the width of 1024 to 640. The content in the image will be reduced accordingly, and the menu text and other details may not be clear.
To avoid this problem, you can use the Zoom function. The principle is to cut the screen.
Set Zoom at a certain time point. Generally, when the mouse moves for a few seconds after the start
Set the corresponding size. I usually set the size to 800x600, and then specify the cropping position in the screen, which is generally the upper left corner of the screen.
After this operation, the image quality is better than that of the finished product with a width of 640, which is equivalent to narrowing down from the width of 800.
However, you must note that some parts of the image will not be visible after the image is cut.
If necessary, you can set cropping multiple times and specify the cropping box in the corresponding position.
Note that you can select Instant in Zoom Speed so that there is no transition effect and a large number of bytes can be saved.

Drag the progress bar to select the position to be disconnected, for example, to delete the content between and
Perform the operation at a.m. in the format of "CTRL_D" or "Edit_Split" and at a.m..
Select this section in the track and delete it by DEL. Note that AVI and WAV should be deleted at the same time.
After AVI is deleted, its back part is automatically moved to the breakpoint, and WAV does not. It must be moved manually.

Step 4: Output
I usually output the video twice. The first time I added the cut effect and watermark to the original video and then output it to the finished AVI format (640x480)
Use Photoshop to create titles and credits, transfer them to the editor together with the finished AVI, and transfer some music files.
Place titles, finished AVI, and credits in sequence in the video track. Right-click an image in the track to specify the duration.
Place titles and credits in sequence in the audio track

In this way, the output is in the SWF format and placed in the webpage.
See Video tutorials in http://99ut.com
The SWF format supports a maximum of 16000 frames. If necessary, the output frame rate can be reduced in exchange for time.
However, a low frame rate will affect the demo effect.

Optimization
Note that this method is suitable for recording screen operations and not for recording movies and videos.
During the recording process, screen changes should be minimized, such as opening and replacing images in a large area to reduce the number of output bytes.
Especially when recording Photoshop and other software operations, do not drag the image window and palette, because recording the drag track takes a lot of space
You can disable the option of displaying content when dragging Windows.

15 frames is the lowest playback speed on the computer.
However, if the computer configuration is not high enough, the response delay may be reduced, for example, 5 frames.
If the number of frames is low, do not move the mouse too quickly during recording, and the display time of menus and options takes longer.
Voice is not affected by the number of frames

I wish you all a satisfactory video tutorial!
