Parallel Processing does what?

[Earlybite]

Hi,

a short question:
What exactly does parallel processing?

TIA and
best regards

Read the FAQ and

Realtime (frame dropping)

This option affects playback and controls two things: when ON: drop some video frames to try to keep the audio continuous and keep the video running near real-time This can make the video to appear choppy or slower frame rate than expected when it is on. Even when this is on it is possible that video processing is so intense that audio becomes choppy as well because Shotcut will not drop video frames indefinitely. In fact, currently it will only drop 5 consecutively (subject to change). Turn…

Maybe I do not understand…
This is for the preview in the source player…<?>.

I thought, my question is in the case of exporting…, because the Check-Box is AFAIK only available in that export dialog window…
So I’m wondering, if maybe the export is slowed down with unchecked Parallel Processing, because of maybe not using multi cores …

From the doc page:

When this is option is off it turns on the same thing as Export > Advanced > Video > Parallel processing .

Maybe, but it all depends and not easy to answer because many variables in projects and systems.

So let’s stay with the export part…

In my case, with my I3-6100 (3,7 GHz, 2 cores) I cannot recognize any difference in speed.
But I have currently “only” that I3.
What it currently does to me, I avoid maybe export graphics issues (if, while export, Parallel Processing is unchecked)…
And I’m still wondering what that Parallel Processing does (in case of export)…, or is meant for.
