Video compressor FAQs
What is a video compressor used for?
A video compressor is a software that reduces the file size of a video. It can do this using two methods. Lossy compression removes data from the video file to reduce its size while with lossless compression no data is lost. If you want to compress video without losing a lot of quality, try a lossless video file compressor like Riverside.
Does compression reduce video quality?
Video compression can reduce your video’s quality, but it all depends on the type of compression you’re doing. Simply put, video compression works through a program or software called a codec. This uses an algorithm to compress a video and then decompress it into a new video format.
Some codecs are lossless and perform compression without heavily affecting your video’s quality or removing data. Instead, they work with the data there is and reconstruct it to make the file smaller. The issue with lossless compression is that it generally isn’t able to reduce a video file as much as lossy compression can. With lossy compression, videos can be reduced into much smaller file sizes but you may lose data and the quality of your video may be reduced.
What is the difference between H.264 and H.265?
H.264 and H.265 are both different codec standards for video compression. The main difference between the two is that H.264 compresses using macroblocks and H.265 compresses using coding tree units. Instead of going into the techy details, this means that H.264 only works with a maximum of 16x16 pixel blocks when compressing a video. H.265 divides the picture into different coding units, working with higher pixel blocks. In short, H.265 uses more advanced technology and compresses more efficiently without losing video quality.
