Question

Premiere loses Render Files!

I'm using Premiere Pro CC 2017 (12.0.0) on a MacBook Pro (2015) running High Sierra 10.13.1.

I am editing a 3 minute long Show Reel with one layer of video files color corrected using Lumetri Pro, Open Captions and Premiere Pro Graphic Title Template Lower-Thirds. The footage is all HD, mostly H.264 and some Apple Pro Res, some Avid Quicktime. The sections containing the titles require rendering (they are yellow but there is no playing back the sequence without rendering, which is pretty disappointing since it's only 3 minutes long).  I'm using OpenCL since Metal makes the entire system slow to a crawl.

I do render to watch it as I edit, however, PP loses link to the render files every time it is shut down and restarted. The render files are still on disk but PP can't seem to connect back to them upon start up! How to fix this annoying bug? On a 3 minute sequence it isn't such a big deal, but on an hour long episode, it would render PP useless, pun intended.

I appreciate any feedback!

Damn, it really works! Tried almost 5 projects

Hint - instead of making all clips enable and re-enable separately you may make all media offline in your project and relink them immediately

It works.

The other possible Solution is to render effects in to out first and only after that make render in to out

I have just tried with two  massive projects and it worked perfect - maybe it will help to somebody

And if you see some red bars after restart program just try to enable and re-enable problem clips  - they should be reconnected

Hey guys!

Absolutely randomly I have just found a strange solution or something like that!

At least it worked for me!

Just disable (or RE-ENABLE) checkbox "Scale to frame size" from the "problematic clips" that lost their preview files. This checkbox magically returns these preview files...

Its not the best solution and I do not understand how it works but you may try to experiment with this

Replying five years later to confirm that this worked for me. Wild that this is still a bug.

Where are the render files living on disc?

Hey Neil, The render files are living in an external scratch disk along with all other project media files.

PrPro doesn't work well with external locations for render files. Move those back to an internal disc, you should be good to go.

We do not have to render again so try and playback in real time, Get the right system and you see real time playback

I don't mean to be dis-respectful, but that is not a helpful statement at all to the user asking the question.
