Rending Nested Sequences - is it advisable?

Does it save time or speed anything up if we render our Nested sequences first. Does it then speed rending up for the main sequence (where the nested sequences are used)?

Things that can significantly speed up exports ...

 

First, if you have ANY clips with Warp, or Lumetri (especially multiple Lumetri on one clip), or video noise reduction, or time ramps/speed changes ... do a full render & replace on those clips in the sequence. Set this to a good intermediate codec like ProRes422, a DNx variant, or Cineform. And also check to include effects and handles.

 

This does all the processing for those clips and gives you new, clean clips that do not require any effects calculations at export. Saves a LOT of CPU/GPU cycles.

 

Second, if you have any AfterEffects comps, after you "finish" the work in Ae, export a FULL intraframe clip of that comp from Ae, and use that to replace the comp on the Pr sequence.

 

Third, if you are say going to export to a full intraframe codec like ProRes or DNx, setting your "preview" files to that exact codec spec, then rendering previews, checking the "use previews" box on export, means that for all clips where the media already exists, it simply uses the pre-rendered parts in the new final export.

No.

 

EDIT: My answer is for rendering, not exporting.

Thanks for the answer 🐵

Are there other ways of helping to speed up the rendering? I have quite a
few looping elements in different nested sequences. So, for example, if I
stick them these elements in the one same nested sequence to simplify the
project, would that speed things up when rendering the main sequence?

It's a 1 hour project and at the moment forecasting 17 hours to render.
