Image encoding complexity¶

Number of iterations¶

As for conventional codecs (e.g. HEVC or VVC), Cool-chic encoding time is variable. A longer encoding gives better compression performance while a reduced encoding time results in slightly degraded coding efficiency.

We present here the impact of the number of encoding iterations on the compression performance by comparing the results obtained through the 3 proposed configurations in cfg/enc/: fast_10k, medium_30k and slow_100k. We used the hop decoding preset.
