There is no point in using more chunks that there are CPU cores in the computer. Chunks can be any number between 1 and 64. Here hap_q can be changed to hap or hap_alpha if you wish to use these flavours instead of HapQ. This will convert Movie.mov to a HapQ movie using 4 chunks and store the result in MovieHap.mov. If you want to use ffmpeg, there are windows binaries to download here: Īssuming you are running windows: Just put ffmpeg.exe and the file you wish to convert in a folder, open a windows command prompt and navigate to that folder and issue the following command:įfmpeg -i Movie.mov -vcodec hap -format hap_q -chunks 4 MovieHap.mov Each chunk will add a slight overhead, both in the form of a slightly higher decoding time and slightly larger files, but the difference is usually (close to) negligible. It the video plays fine without using chunks, don't bother to use chunks. If the bitrate is too high, you will have to render to a lower resolution, or, if playing HapQ, switch to Hap. The compression methods are fixed and leave no room for any adjustments.
As I have mentioned in previous posts, given a certain resolution and Hap flavour (Hap, HapQ or HapAlpha) there is no way to control the bitrate.
