x265 chunk encoding usage

I'm trying to figure out the proper usage of the --chunk-start and --chunk-end options introduced in version 2.9

I guess it works as described but what is the use case here? I thought this is intended for parallel processing but it seems ALL the frames before --chunk-start are fully encoded and then discarded.

So instead of reducing the turnaround time this is no faster than a single complete encode and the total amout of processing time is MUCH higher.

Any comments? Thanks.
