2024年11月1日 · What is a Certified Quality Technician? A Certified Quality Technician (CQT) is a professional who supports quality assurance and control processes by performing inspections, collecting data, and analyzing results. They play a critical role in ensuring compliance with quality standards and improving product reliability.

Before applying for the ASQ® CQT certification you might want to do is to check if you qualify to appear in this exam. You need to have a minimum of 4 years of work experience in the area of CQT Body of Knowledge. However out of four years of experience, three years can be waived off if you have a Bachelor's degree.

适用场景：带宽约束下的流媒体; 直播（指定CRF，1-pass）; VoD流媒体（目标比特率，2-pass)。 可用于2-pass VBR（在两遍中使用它）。 注意：使用1-pass方法也可以 - 根据x264开发人员 - 通常与2-pass一样好，但压缩效率低一些。

2022年12月28日 · 在x264 x265中，crf / cq 取值范围是 0 - 51。x264中crf /cq 默认是23，x265中默认是28。数值越高压缩出的码率越低，图像质量越差，根据经验来说，一般crf / cq数值每增加6，码率就会下降为原先的1/2；反之crf / cq数值每减少6，码率会增加为原先的2倍。

CQE Exam Preparation Tips and Tricks - This is one of the oldest certifications (and the most difficult to pass the exam) offered by ASQ. You need 550 marks out of 750 to get certified. The computer-based CQE examination consists of 175 multiple choice questions, a five-and-a-half-hour exam and is offered in English only.

What do my grades mean? Used for a composite mark in the range 84.50% and above (85 – 100% when rounded to the nearest integer). Used for a composite mark in the range of 74.50% – 84.49 (75 – 84% when rounded to the nearest integer). Used for a composite mark in the range of 64.50 – 74.49% (65 – 74% when rounded to the nearest integer).

2017年3月1日 · 本文深入探讨了视频编码中的码率控制模式，包括Constant QP、自适应码率（ABR）、固定码率（CBR）、二次编码自适应码率（2-Pass ABR）、固定质量（CQ）/ 固定码率因子（CRF）和受限编码（VBV）。

If you pass the exam, you will receive a certificate verifying that you are an ASQ Certified Quality Engineer. If you do not pass, you will receive a diagnostic report outlining areas of strength and weaknesses to better prepare for your next attempt.

2017年9月11日 · CQ mode is available for one-pass encodes, but is generally intended for two-pass. For one-pass, CQ applies the user cq-value, but can't adapt to a higher value if the clip is difficult. Specifying passes=2 has no effect: only a single pass is performed.
