Need help with export times

I am new to Shotcut and video editing. I use Linux Mint Cinnamon 20.2 on a 7 year Dell XPS.

Using Shotcut 21.06.29. Just starting using it last week. Neat program and I look forward to learning how to use it. However, when I export a video, it takes hours to complete.

I am downloading a Zoom recording such as ‘file_Recording_640x360.mp4’. (500 MB). I trim off a few seconds (usually the beginning & end) and then export it.

I try to minimize the export file size so I can upload it to YouTube. Currently I export as preset ‘Slide Deck (HEVC)’. I would like to maintain video quality & minimize the file size.

Can anyone give suggestion(s) on what I can do to make the export run faster?

TIA

RAM and CPU are usually responsible for performance. You said it’s an old XPS? What are the specs?

Using HEVC is causing the big slowdown. Try Slide Deck (H.264) which will be faster and the same visual quality, yet still be a significantly smaller file than a typical H.264 export (usually by a factor of 10).

@Austin,
Good suggestion!
Slide Deck (H.264) took a little longer but the file was much smaller than the HVEC option!
Thank you!

I’ve not used it with LINUX - but with WIN 10, I do a full re-start of the computer, start ONLY SHOTCUT and do the export. Mine take about 1½-2hrs though (for a 1¼+/- video from 2 or 3 .MTS files. And having restarted, I can save export time by up to 30%.

The other factor - the more FILTERS you have in use have a considerable effect on export time.

I’ve just added RAM to mine 2 days ago (8->12), so it’ll be interesting to see how that helps when I download this week’s 2 Church services in a couple of days.

Alan, I do not use any filters (have not learned about). I have tried a few export options and I think I’ll YouTube w/ hardware encoding since that it is ending up there. Seems to have reasonable time and file sizes.

TY
