Everything in nest re-renders

[Jan Franzén]

Just export it to a new file by using export-quicktimemovie. Use “current settings” “audio video” as you like and I usually set markers to none.
After named and saved import the clip and you have a new fresh clip to go on with.

[John Steventon] “I render the broadcast safe filter, it wants to re-render all the filters again. This is concerning…”

I wouldn’t call it “concerning”…

It is how FCP is designed to operate (and it is a big QUALITY ADVANTAGE over Avid.)

With Avid, it is possible to render, then add an effect and RE-Render the first render, and so forth (creating “render-generation-loss).

FCP will always go back to the original files and create a “fresh” render which can yield less visible image “degradation”.

Yes, it does take longer if you don’t add all of the filters you want before you render.

The workaround stated (output to QT, re-import) will work, but it “forces” FCP to make an “Avid-style” render (re-rendering a render)… but if you don’t mind (and can’t see any image-loss, go ahead.

Add the Broadcast Safe filter BEFORE you do the final render. FCP always renders everything from start when a new filter is added.

So tweak all your filters the way you want them, then drop a Broadcast Safe filter on every clip, render.

Sounds like you’re doing it correctly. How exactly do you KNOW that it’s rerendering the already nested effects?

You might be doing this… Are you nesting your layers and THEN highlighting the nest and rendering? That would produce the problem you describe. Adding an effect to the nest in that case, would be like adding another effect to an already rendered clip. It would require rerendering. What you want to do is render the contents of the nest ( if already nested open the nested sequence, render it, and close it) and then add layers above or add filters to the nest. Only in this manner will the nest be treated as a single clip, and the render files for the nest be utilitzed as the source files for any added effects or layers. FCP absolutely does NOT always force rerendering from the ground up.

For example if you layered up 20 clips and it took 10 hours to render, you can nest the rendered items, then add another layer above the nest (not in the nest of course) and it would be the same as rendering 2 layers together, not 21. So the rendering should be very quick (or real time) when you add that layer.

The same goes for applying a filter TO the nest. It should act as if you’re applying the filter to a single clip. It does not re render all the effects within the nest. This is the beneficial way FCP has worked since version 1 and it’s extemely powerful. I’d be extemely surprised if Matte and Walter truly thought FCP was as limiting as they describe. I think they or I must have misunderstood your question.
