H.264 (also known as MPEG -4) is currently one of the most commonly used formats for recording, compression and distribution of high quality video. Its compression quality out-performs any other codec in the market today. H.264 can be played on almost all modern browsers and is typically shared in MP4 containers. With so many benefits, you may want to explore the possibility of using H.264 codec for your videos. Here are a few tips on the options that you can customize to achieve best results:
Constant Rate Factor (CRF) is a bit rate control settings and sets a constant rate factor. CRF mode generally delivers better results than constant Q encoding. This is achieved by reducing the quantizer quality on “less important” frames.
H.264 profiles: There are three commonly used profiles – Baseline (which is the lowest), Main and High. It’s easy to decode baseline profiles, but higher levels offer better compression. Medium and High profiles are best suitable for web playback delivering best results. Baseline profiles are best for Mobile device playback. There are profiles with other capabilities, refer to the list of profiles to choose the one that best suits your need.
H.264 levels are primarily for device compatibility.They constrain bitrates and macroblocks. You may want to consider using this settings if you are targeting a specific device. Here’s a list of valid values that you can consult.
Tuning: You can optimize your video to suit a specific content type. For example: you can use ‘film’ for movies, or ‘animation’ for animated videos. The valid values include: film, animation, grain, psnr, ssim, fastdecode, or zerolatency.
H.264 is an advanced codec and currently an industry benchmark. There are many other options that you can customize to generate the best outputs. So try experimenting with the settings to get the best settings that suit your needs.
