Different Video Encoding Formats and Trade-Offs - Cardinal Peak
Summary
Other compression trade-offs include the application’s visual quality requirements, the transmission channel’s environmental characteristics (speed, latency and error) and the source content format. The H.265 codec compresses information more efficiently than H.264, resulting in video files of comparable quality that don’t take up as much storage space and require less bandwidth to stream. The challenge for AV1 today is that devices capable of decoding AV1 streams are lacking despite recent Amazon-led efforts to increase adoption, so the codec is not yet supported on a large scale. The file format that arguably made portable digital media possible and popularized digital media players like Apple’s iPod, allowing users to exchange audio at scale online and carry hundreds of songs in their pockets, MP3 is supported by nearly every audio device but offers inferior compression for perceived quality when compared to AAC. Whether users will be utilizing Sonos, Alexa, Amazon Fire, set-top boxes or other popular media clients is another important factor since each has its own list of supported technologies — it’s a veritable Rubik’s cube!
