media compression

Today, I will learn what media compression is. This is my most interesting topic because I really like editing videos. In this topic, I have some understanding of media compression, but I don't know how it really works in the media. The knowledge I have is that I know that higher compression rates have lower quality. I also know that the quality between 144p and 2140p this is the quality of the video, but I don’t know how it works, I think this is the reason for learning it.

In today's topic, I have learned a lot. The first thing I learned is video compression in video compression. I know that each individual image that makes up a video is called a frame. When you have more frames it means you have a higher quality video, but more frames are also means you will get larger files. The second thing I learned is how to make the file smaller. I used to lower the frame because a low frame rate is the easiest way to reduce the file size, but lowering the frame rate will also reduce the data rate. In today’s task, I also learned 3 different ways to shrink the file. The first method is, if you you have to think that do you need the bright colors in the video?if not you can removed the colour. The second method is to change the size when you have fewer pixels, thereby making the file smaller. The third thing I learned is that sound can also make your files smaller. The reason is that when you have higher quality sound, you need the largest file, but if you reduce the quality, it will also reduce the file size, but It depends on what you need for better sound quality.

In today's topic, I also learned the diffrent type of compress types, such as lossy and lossless. The difference between them is that lossy will Damaged, deleted or "lost" information. On the other hand,  lossless compression of the file, no information will be lost or changed however this is not a very effective way to reduce the file size.

Peer Review #2

Today, i finished the reading tasks. What I need to do is I need to write feedback from 2 other students. The first step is to learn the SPARK method, I learn what is specific, prescribed, operable, reference and kind. I think these methods are very useful when providing feedback to others. I also think that this method can bring the greatest benefit to those who receive the feedback. The second point is that I have write 2 feedback. So I go to the blog and write down some important notes, because it will allow me to understand what they are trying to say and also give them the best feedback. When I gave her feedback, I used a specific and standardized method for the first blog I also made some suggestions I also used the specific in second feedback and used the referenced method because I think the blog is really good and I have nothing to give feedback, but I try my best to give them Feedback In this lesson, I learned how to use the sprak method and how to provide feedback. I also le...

study skills

Today, I want to talk about the valuable information I found in the study skills video. I found the first thing is the active recalled. Active recall means that you must recall what you know without looking at the answers. I think this technique is very good compared to my previous experience. From my previous experience, I read the text many times because it is the easiest method and there is no pressure but the most efficient way of learning is active learning. Even if you think that active recall is a difficult way to learn, but it will make more effort and will make your brain more active, which will allow you to get better retain knowledge. The second thing is spaced repetition. I also knew this technique before watching the video, but I didn't do it. After watching the 3 best science learning techniques I understand the benefits of spaced repetition. spaced repetition makes your learning more efficient and easy because you should know that the longer you wait, the harder it i...

technological evolution

Today I want to talk about technological evolution. Our human evolution began 1-2 million years ago. Fire began. Humans discovered fire. We can see that humans have begun to understand the environment. After that, we can see that in 1650 we have a pendulum clock. That means we have the correct clock. After It was one of the world’s first personal home computers in 1976 that did not go deep into the technical part at that time. This is the beginning of technology, but there are no media yet. But in 2020, we have quantum computers, and our technological development has undergone great changes at this time. For example, we must know what copyright and media literally and other things. This also shows us that our technology has changed a lot and changed so quickly. However, it wasn't until around 1960 that media literacy as a term or field became "one thing". We can see that the media is developing so fast, and we are not ready yet. I also think that in today's society, w...
