I have a system with 8 GB memory.
When I try to re-encode a video with size e.g. 500 MB or even 1 GB then I observe permanent
hard disc activity during VD run.
Hardly any other pograms run on my computer at this time.
I guess VD is reading step-by-step only chunk portions of the source video and writes the resulting video
in portions to the hard disc.
I wonder why VD is doing this.
Wouldn't it by MUCH better to read the source video completely into memory, then process the re-encoding completely in-memory and finally write the result video to hard disc?
That would be 10 or 20 or 50 times faster.
Could you consider this full in-memory-processing for the next release?

Well, you could install a ram disk like (zero cost) https://www.softperfect.com/products/ramdisk/
Then you could test your theory
Be prepared for disappointment though as disk access is rarely a bottleneck, let alone the cause of a 10x slowdown

Will not.
Acceleration will be small and not as you dream. |
