Render files (Video Preview files) go offline unexpectedly - Green render lines become yellow or red

[S_Dale]

Hi, I have been having problems in the last few days with rendering. Every time I render a timeline, it seems to work and then all of a sudden go back to yellow/red as being unrendered. I have tried loads of different things but have no more ideas. Plesae help! I have added a video to show what I mean. 

Many thanks

Where do you have your scratch disks?

The drive may be filling up.

Are you making any changes to the timeline which would make Premiere recognize it as un-rendered?

Hi S_Dale,

Sorry. What do the sequence settings say? Can you show us a screenshot so we can see the codec you are using to render your effects? Do you have network drives for storing your rendered video preview files?

Thanks,
Kevin

Hi there, 

I have attached screenshots of the various settings I have. The drive I'm rendering to still has over 500GB of space available, but I'm not making any changes to the timeline while it renders as the video shows, it seems to revert back to undrendered even while it is 'rendering'.

Any help would be great thank you.
