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.

Thanks Ben. Should this be used in conjunction with --seek and --frames then?
So if I wanted to encode frames 1000-2000 (24fps, 1s VBV Buffer, 1s RC Lookahead) I'd roughly use: Code:
--seek 976 --chunk-start 24 --chunk-end 1024 --frames 1048 |
