"Per ongeluk" heb in een drie minuten filmpje ge-edit in adobe premiere Beta. Momenteel is mijn PC dit filmpje aan het renderen. momenteel heeft het systeem 22% gerenderd; nu nog 2 uur en 30 minuten te gaan. Help!!! wat gebeurt hier?

Hey ​@janL , the preferred language here is English.

Could you tell a bit more about the contents of your video and system hardware? A good way to see where things might start to hang due to possible issues is to pre-render the timeline before exporting.

If you prerender in a format high quality enough that you can use it to export your actual file too this can save a lot of time if you don't make much changes that affect the timeline as a whole.

Try the following:

• Go to Sequence → Sequence Settings… and set the Video Previews to Apple ProRes 422, 422HQ or 4444. Enable the 3 quality checkboxes at the bottom too.
• Select the contents of your full video in the timeline and hit forward slash “/” to create In/Out points for it and make sure you can see the whole timeline in one view.
• Go to Sequence → Render In to Out
• Pay attention to where the bar below the time ruler turns from yellow to green and where it possibly gets stuck.
• If it gets stuck check what is happening there in the timeline. Maybe some effects or media aren't playing nice for some reason.
• If you were succesful in rendering the entire timeline, what you can do is go to the Export tab and pick “Match sequence preview settings” as the export preset. This will use the already rendered ProRes files rather than recalculate the entire sequence so should be a guaranteed export. If you need other formats as export afterwards you can convert them with Media Encoder from that master ProRes file.

Hope that helps.
