Rendering Again a Finished Video
on Aug 21, 2017 at 12:07:07 am

I am working on a film project for our organization which has a length of 2 hours. I edited and rendered in Quicktime Apple Prores 422 since this is the format required by a film producer. After finishing the film with the said format, I got almost 60GB in size. My computer is terrible so it took me 12 hours to complete the render.

Now, I made a little mistake to the film. Need to re-edit and render again...and possibly wait for another 12 or more hours. Unfortunately, we need the final video tonight. I am thinking of editing the "completed video" and just render it again instead of editing the .aep file full of effects and color correction because I am thinking it will SOMEHOW make the rendering faster. My questions are:

1. Am I correct to assume that using the "completed video" in post-production/editing will make the rendering faster compare to a layered project full of effects?
2. I want to retain the output format (codec, framerate, resolution, etc) of the video. If number 1 question is possible, will the output of the "new completed" video stay the same after rendering?

Thanks for all the help!!

Render only a second before through a second after the change. Note the time code cut it into the existing export.

1) Export only the portion of the timeline you have to change. Pick convenient cut points before and after the change for in & out points.
2) Import the existing 60 GB file.
3) Import the small changed part
4) Put the existing 60 GB file in a new timeline. Cut out the bad part.
5) Put the small changed part in its place
6) Re-Export.

This is the best way. I do it all the time when needing a fast fix and it works perfectly.

large renders should be image sequences so you can re-render individual frames if necessary(and leave off after an error). Wavelet codecs like prores, dnxhd, cineform are lossy, although very high quality and need re-rendering unless you use them in a special smart codec way. If you do it right, they can export 4-12x faster!
