how to use ffmpeg to encode binary pixels

The default is 1 and should never exceed the number of CPU cores in the playback system. Chunked Encoding/Decoding: For the HAP codecs a chunking size can be set as an optimization for specific hardware.Quality: When available adjusts the overall tradeoff between image quality and encoding speed.In addition to specifying a video codec, when using the HAP codecs the following sub options may appear depending on the format. For audio and video you can specify whether the media should be transcoded or left unchanged. Output Format: Click the 'Settings' button to open the panel for adjusting the audio and video codec setting options. Files To Convert: Drag movie files to this area from the Finder or click the Import button to select media to be transcoded.Consult the documentation for the systems you are working with for more information.īatch Exporting on macOS with the AVF Batch Exporter As a general guide, for HD footage or smaller you can set the chunk size to 1 and for 4k or larger footage the number of chunks should never exceed the number of CPU cores on the computer used for playback.įor encoding to HAP from Adobe AfterEffects, first export to an intermediate format and use one of the below solutions, or try the 3rd party AfterCodecs plugin.Īdditionally some media servers provide their own method for importing media to convert to HAP and can be used as an alternative where available. This setting should typically only be used if you are reaching a CPU performance bottleneck during playback. Some encoders allow for encoding with an optional specified 'chunk' size to optimize for ultra high resolution video on a particular hardware system. HAP Q Alpha has improved image quality and an Alpha channel, at the expense of larger file sizes.HAP Q has improved image quality, at the expense of larger file sizes.HAP Alpha has the same image quality as HAP, and supports an Alpha channel.HAP has the lowest data-rate and reasonable image quality.There are four different flavors of HAP to choose from when encoding your clips. Choosing The Right Codec For The Job: HAP, HAP Alpha, HAP Q and HAP Q Alpha avi containers just like other video files you are used to working with. Movies that are encoded with the HAP codecs are typically exported into standard.
