How to compress video file for Web or Email? I have a video file that is 126 MB in size and could not send it via our webmail because it could only accept 5MB file attachment. – from Yahoo Answer

Video file is too large for email (10-50MB) or for uploading to WhatsApp (max 16MB), Facebook (max 1.75MB), Vimeo (500MB/Week), as is often the case, for most video sharing sites have maximum file size and duration of a video file.

How to Compress Video Fast Without Losing Quality

Step 1: Free download the video compressing software Mac version . Run it and hit “Add File” to load the video file you wanna shrink.

Step 2: Select the output format. For example, if you want to compress MP4 file size , you can select smaller-sized FLV or WMV as output. Based our test, the free video compressor shrinked a 490MB 4K MP4 file size to 28MB HD FLV video in 1 minute and the output video was great.

Tips: You can adjust video settings like resolution and bit rate to downsize the video file. It is recommended to decrease the default bit rate by 20-50%. Video demensions also influence file size greatly. For example, 3840x 2160 (4K) will have more horizontal lines than 1080P, and therefore large space to store the extra information. For regular users, 720P and 1080P are good enough. Please note that uncompressed audio will make a difference in video size. If you’re not a devoted audiophile, adjust the audio bit rate if necessary.
