 Hi Everyone! Today I watched a few videos about video compression, video format, codecs and containers and I found them extremely helpful, so I would like to share my thoughts about them. There are 2 ways to compress a video which is spatial compression (intra-frame)or temporal compression (inter-frame). Spatial compression is applied only to individual video frames. To compress a video frame it is the same process that is used to compress a still image like a JPEG. When JPEG is created, colour information of the image reduces in the process called chroma subsampling. Then the image is split in sections of 8x8 pixels called macroblocks. Then the file size is reduced. For MPEG (motionJPEG) it's more complicated.  Temporal compression works by reducing redundancy, like JPEG the MPEG standard breaks a video frame into 8x8 pixel macroblocks and each macro block receives instructions on what to do with pixels they already have. There are instructions for staying exactly the same f...

  Hi Everyone! This week I had my peers give feedback on one of my blog posts, and I had to rewrite my blog post based on the feedback I got to create a better post. I found this week's blog to be quite difficult as the feedback was very positive and I honestly didn't know what to rewrite or what to do as I was happy with the post already. It took me a bit more time than I expected but I did end up rewriting it successfully and I'm even more happy with how it turned out in the end. I read an article that really helped me rewrite my blog. In the article what really helped me was when I looked at the relevance and importance of the content that was in the feedback. I realised that I needed to give more factual information and less of waffling about unnecessary information in my blogs. I also thought about the things I could have included and why I didn't include them. Where I was going with my sentences in some areas and if they were clear to the audience and not just me....

Hey Everyone! Today I watched three videos about cameras and audio. I found them extremely useful for my photography and my videos in the future so I would like to share them with you. There are 5 camera basics that everyone needs to know to make professional photography and videos. The first one is Frame Rate. This tells you how many frames are in 1 second of your video, For example we shoot a video in 1 second with 30 frames. It basically means it takes 30 photographs in 1 second. The industry standard is 24 FPS "most cinematic", This is the most natural looking motion. If you want to do a slow motion you do it on 60 FPS so when it is slowed down it is clean and smooth.  There are 3 settings to get correct exposure which is the ISO, shutter speed and the aperture. The second one is the ISO, usually known as "fake light" . It's a way to make your image brighter or darker completely digitally. The down side to this is that it produces noise/grain in the image/ w...
