![]() ![]() You can also get elbow sleeves with added protection, such as in the Nike Contact Support Elbow sleeve. Elbow sleeve - An elbow sleeve keeps your arms covered and protected from bumps and scrapes.For example, a golfer might wear this to prevent overuse injury during training. Glove - A glove compression is used to support the wrist.A tennis player may wear this during training to protect the arm against injury. Upper arm to hand - This includes a partial glove and encourages blood flow up into the arm stopping just before the shoulder.There are multiple different types of upper-body compression wear, but here are some common examples: Some people also wear compression arm sleeves on airplanes to prevent deep vein thrombosis, because the pressure from the compression stops blood from pooling and clotting. You can also wear the arm sleeve during a workout to help blood flow, or afterwards, to help recovery. To choose this option, choose "Re-size video" from "Advanced Settings" above.If you’re asking yourself, “When and where would I wear an arm compression sleeve?” The answer is: During any sport that requires upper-body activity like running, basketball, tennis, golf, volleyball, football, or weightlifting. For example, if you have a 4K (4320p) video but your target device is 1080p, you can downsize the video to fit 1080p and save file size. 4: Make Video Size Smaller (Re-Size)Ĭhoosing a smaller video resolution (dimensions) can also save file size. For more info: read video bitrate control. To choose this option, select "By Max Bitrate" from the "Video Compress" dropdown. Select this method if you are using the video in a streaming application where you want to control the streaming bandwidth rate. The quality is set by CRF (constant rate factor). This method allows you to set the max bitrate for given video quality. This is the default video compression method used. Increase the target size if you need better quality. To overcome this, start with a decent size (as a percentage of original), then test for video quality. The downside is you don’t know how the target size will affect video quality. The pros of this method are, you can achieve a certain target size. For example, if you set it to 60% for a 1Gb file, we will attempt to make your compressed file size 600Mb or less. This method allows you to set a target file size for your video as a percentage of the original size. As a Percentage of the Original Size (Default) If you prefer a lower file size over encoding time, choose a slower preset. Choosing a slower preset allows better optimization (lower bitrate/file size) for a given video quality level. Preset: Presets refers to the video compression speed. Higher values mean more compression (reduced file size), lower values mean better quality (but bigger file size). For the H264 encoder, possible CRF values range from 0 to 51. To do that, it uses different compression levels on different frames. By Video QualityĬRF (Constant Rate Factor): CRF method attempts to keep a constant perceived video quality. We provide 4 settings related to both methods. You can either optimize the bitrate or resize the video to a smaller size. There are two main methods to compress a video.
