Generally, you'll see files measured in kilobytes, megabytes, gigabytes and terabytes: What's a byte?Ī byte is a unit of measurement used for digital files. Alternatively, you can upload your uncompressed video into Dropbox and share without worrying about compression. If the video is long, it will take a very long time to compress, so you can waste a lot of time if you export as the wrong file format. Most video editing programs will let you choose your resulting file format, including MP4, AVI, MOV, and WMV. These programs require you to open your video, usually by clicking "open" or "import." Then, exporting converts them to a new file type. Alternatively, you could send your video in a ZIP compressed file, but this will require your recipient to download it on their end. Most video editing programs, such as iMovie for Mac or Windows Video Editor for Windows, come with a built-in video compressor. This is when things start getting "pixely," "grainy," and generally not viewable. You'll only start to see compression wreak havoc on display quality if you want to shrink a file down to a tiny file size while maintaining resolution. Think about how a Hollywood movie goes from cinema screen size to a DVD, playing on any home TV without lag. To the human eye, this loss is hardly noticeable. Video compression occurs by removing repetitive images and sounds as determined by the codec algorithm. Depending on the original size, this quality loss may not be noticeable, but that all depends on how small you need your video file size. However, it usually means overall quality takes a hit. Essentially, compressing your video cuts a chunk off the size needed by your file. That means your video won't fit into your message, or your recipient can look forward to a lengthy download period on their end. Unfortunately, almost all file sharing methods, from email to instant messaging, have file size limits. Video compression is a way of shrinking your video file size. Compressing your videos solves this problem. Sharing high-quality videos between teams and clients can be frustrating since video files size are bulky at the best of times. If you can't achieve the file size you require with these methods, consider resizing the image to smaller dimensions or cutting the animation duration.Technology is a wonderful thing, but there are still some things that can make even the most tech-savvy person get a little anxious. The fuzz factor represents how similar colors can be considered as equal. It will give poor results for converted videos or photo slide shows, where most pixels between each frame are significantly different. It may give huge file size reduction in some cases when images have large, static areas, e.g., a recorded screen capture of some program. The results heavily depend on the nature of the image. This option keeps the first frame in the background and makes unchanged parts of the following frames transparent. This will not do anything for most GIFs but can be useful in some special cases. This method will search for identical or very similar consecutive frames, remove them and merge their display duration. Useful for long gifs with a high frame rate.Īnother option is to remove only duplicate frames. The frame drop option can remove every second, third, or fourth frame to reduce frame rate and, therefore, file size. It makes multiple variations of your input image, and you can choose the one with the best size/quality ratio for your needs. This tool shrinks the GIF file size by reducing the number of colors in each frame.Įach GIF frame can use up to 256 unique colors, and by reducing this number, you can achieve a smaller file size. This is the default method and should work for any GIF. You can adjust the compression level with a simple slider to get the best result for your use case. It can reduce the animated GIF file size by 30%-50% at the cost of some dithering/noise. GIF compressor optimizes GIFs using Gifsicle and Lossy GIF encoder, which implements lossy LZW compression.
