Video editing usually refers to the use of professional equipment and technology to post process captured images or audio, including editing, color grading, dubbing, adding special effects, etc., in order to produce audiovisual works with specific purposes and styles.

The 24.000MHz frequency crystal oscillator, as a commonly used crystal oscillator on system motherboards, is characterized by its COMS output, package size of 2.5 × 2.0mm, optional voltage range of 1.62V~3.63V, and frequency difference of ± 50PPM. It is a great choice for recording and editing.

The role of crystal oscillators in video recording and editing is mainly reflected in providing stable clock signals to ensure synchronization and precise control of video and audio signals. The following are the specific functions of crystal oscillators in video recording and editing:

1. Stable timing reference: The crystal oscillator generates precise and stable clock signals, which are used to synchronize and control various operations in the recording and editing system, such as video capture, encoding, decoding, etc.

2. Used for frequency synthesis: Crystal oscillators can serve as a reference source for frequency synthesis, obtaining the desired frequency signal through frequency division and doubling techniques.

3. Support for precise timing: For video recording and editing applications that require precise timing, such as high-definition video processing, real-time editing, etc., the precise clock signal provided by the crystal oscillator can meet the needs of these applications.

The programmable oscillator SG-8018CG (X1G005601045900) launched by EPSON has the following application characteristics in video recording and editing:

1. Accurate frequency output: High precision clock at 24.000MHz: SG-8018CG provides an active quartz crystal oscillator frequency of 24.000MHz, supporting a wide frequency range of 0.67-170MHz. This high-precision clock signal ensures stable data transmission, avoids data packet loss and transmission delay, and improves the processing capability and efficiency of recording and editing equipment.

2. Wide operating temperature range: The oscillator maintains a frequency stability of ± 50PPM within the temperature range of -40 ℃ to+105 ℃. No matter what environmental conditions the equipment is in, SG-8018CG can provide stable clock signals to ensure long-term reliable operation of the equipment and meet the requirements of harsh working environments.

3. SG-8018CG adopts a 2520 package size to meet various circuit design requirements, while also having high cost-effectiveness. The compact packaging design not only saves space, but also improves integration, providing flexibility for device design and layout.

4. Suitable for commercial audio use, with application scenarios including audio processors, video processors, recording editors, etc;
