Clips with a green bar get a red bar when I move them on top of each other

This is the way it works, after rendering if anything is changed you will have to render that portion again.

Hi Richard,

Thank you for your help and your reply.

I”m convinced too that you should render again if you change anything (like contrast or scale etc.), but the strange thing for me is, I only copy the clip from a sequence and I paste it in another sequence on top of another clip and all of a sudden I have to render it again.

When I make the track below the just copied clip invisible, the red bar on top of the just copied clip disappears and turns green again. So it has something to do with the fact there’s a clip below the clip (although opacity on both clips is 100%)

Normally, that shouldn’t happen I think?

Thank you for your help,

Hi Richard,

Something else: my sequences have the same settings. So it has something to do with the fact there’s a clip below the clip with the red bar.

Thank you,

I can have a 100% opaque video on track 2 completely covering a video on track 1. If I add lots of effects to the unseen video often I will get a red bar over that section. Premiere seems to start working out the pixel value from the lower tracks upwards even though they are covered by a video that does not need rendering.

I think the bars indicate the SEQUENCE’s play-state of readiness, which is more than any single clip attribute. It also reflects the system;s capacity for real time playout, factoring in more parameters. If you stack two native clips, it probably flags that portion as a bigger CPU/GPU load, so it flags as a render.

Hi Michael,

Thanks for your answer.
Would this be the case even if the lower clip has a rendered preview, and a green bar in the sequence?
Also, next to that, the lower clip doesn’t have a lot of effects, it’s just footage without any effect applied to it?

Thank you for your help,

I’d guess so…stacking being an automatic flag. The only way a clip is free to move is if it’s by itself on the timeline and is the EXACT matching codec and wrapper as that of the sequence. The best way to do that is a direct export from PP, in which case when you re-import it, there won’t be a bar on it all. Even so, a bar doesn’t really impede the editing much if your system has adequate media drive speed and enough RAM to process in real time with low load. DVCCPro for instance, is pretty much as slick as standard old DV….

Hi Michael,

Thanks for your answer.
Hmm, perhaps the problem could be the RAM indeed…
I’ll try to edit as much as possible on separate sequences before I copy all my clips into one sequence.

Thank you!

The more I’m working with it, i’m discovering more.

The lower clip is actually a sequence of TGA’s (a slow motion with made with twixtor), I rendered a preview of it, but perhaps it’s better to export first a movie of that sequence and re-import it again in premiere, without using a preview render.
