Do you have a video that you want to upload to a site such as YouTube? You may have noticed that raw video files no matter what they are MP4 file formats, especially HD video, can run several gigabytes in size. While you can upload large files to YouTube and Vimeo, this can take a very long time. Also, these services will compress your file once it is uploaded, and often the results are not very high quality. In that case, compressing your video yourself is the best way to allow you to control both the size and the quality. This article can assist you to discuss how to reduce or compress your MP4 file size for better uploading or playback on Windows and Mac.
For those of you who just need the settings, here are our basic recommendations what to use when compressing MP4 video (where the original is 1920 x 1080 pixels) for upload to the web:
Format MP4 (file extension .mp4)
Codec: H264 (High profile)
Frame Rate: 24, 25 or 30 (Constant)
Frame Size / Resolution: 1280 x 720 (720p)
Bitrate: 5,000 – 10,000 kbit/s
Bitrate: 320 kbit/s
Sample Rate: 44.100 OR 48,000 kHz (retain original sample rate)
See, one complete video must includes the file formats, codec, frame rate etc. that means, revising any one of them will brings changes in output size and quality. For example, if you start with a 10 minute video, and choose 5000 kbit/s video bitrate and the settings above, the file-size of your compressed video will be about 400 MB. If you choose 10,000 kbit/s your file-size will be about 775 MB. You can use this guide to estimate how big your video will be - if your video is twice as long i.e. 20 minutes, it will be double this size i.e. about 1.5GB.
