Experience of screen recording experts

When using screen recording experts

There are four things to consider:

First: compression rate

Second: Sound Source

Third: Anti-Piracy text display

Fourth: file cutting and merging

First, the compression ratio is controllable,

If you select the WMV format, the system will prompt whether the video is selected for the video content. If it is a demo, you are not advised to check this option.

The dynamic bit rate automatically generates the video size by default, which is generally large to ensure quality in all aspects.

If you select a fixed bit rate, the bit rate has two categories: automatic and set,

The default value is 500. However, after testing, the value is changed to 400,300,200, and there is no difference in the eye discrimination scope,

However, the file size is reduced by a considerable amount, which increases the "compression rate ".

Second, in terms of sound source, you should pay attention to testing. Sometimes the default source is the microphone, which needs to be changed and tested for recording.

For different sound cards, the quality of the initialized recording is different and must be selected for test.

For example, the recording effect of an IBM notebook is recorded together with the outside voice by default. This is a bad phenomenon.

The anti-piracy text shows that this item is not controlled and sometimes unavailable. Generally, it is selected when the first recording is started.

If the text does not appear and the fixed bit rate is not displayed during recording, you can use the most absolute method: Back up the pure system, and then install the screen recording software, when pirated text is displayed, restore the original system and reinstall the screen recording software.

For file cutting and merging again, the software uses the default recorded file as the default cut file. If the file does not exist, it cannot be cut.

You can cut a custom header and end. After the definition is finished, you can cut it. The same applies to the same format in the same default directory.

Files with the same screen size ratio can be merged, and files with different sizes cannot be merged.
