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. Singling out a free video compressor that saves your money and energy is a right way to go. I sorted out some freeware to compress videos like MKV, AVCHD, MP4, AVI and other large-sized videos with a brief breakdown of their pros and cons to help you make a well-informed decision.
Part 1: macXvideo - Reduce Videos to 90% Smaller with No Quality Loss!
A 100% free video compressing tool is recommended - macXvideo (or Windows Version). Its advanced compression engine can shrink a video size by 90% smaller. Plus, it also ensures the fastest speed and excellent quality thanks to built-in High Quality Engine, multi-core CPU, advanced hyper-threading and hardware acceleration tech.
See, it can compress MP4, MKV, MOV, AVI, AVCHD, 4K, 8K, to FLV, WMV, 1080P, 720P, etc. much smaller-sized file fomats or resolution (180+ video & 14+ audio output formats) and stunning parameter settings adjustment (Bit rate, frame rate, resolution, etc.). The video editing features further shrink the video size: crop video bars or unwanted black parts; trim video to cut off the needless video clips to get the desired video length, add or extract subtitles from video, etc. All these tasks will be achieved in mins or even secs, Intel QSV/AMD/Nvidia hardware acceleration improves the speed up to 5X faster than any other compressors. Follow the steps below to reduce video file size.
How to Compress Video Fast Without Losing Quality
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.
Step 3: Beyond format and video settings, you can also reduce the file size via its excellent video editing feature. Click the editing bar below the video information to enter into the editing window. Specifically, you can trim off unwanted parts, get rid of the black bars, etc, in such a way, the video can be reduced, even without compression. See detailed video compress tutorial on Mac.
Step 4: Hit "Browse" button to save your reduced video file. After you've shrinked video file size, click "RUN" button to start to bring down video file size.
