Pre-Timeline mode

PostWed Aug 19, 2020 1:41 pm

Hi all,

It would be great if we'd be able to have Pre-Timeline mode, in order to apply a treatment to the whole timeline before the Clips node window.
This would work the same way as a Group Pre-Clip, except that you wouldn't have to group the whole timeline clips to do it.
It would be very usefull for global pre-processing like add grain, Color Space Transform, denoise, etc.

Thanks.
Alex.-

That’s an interesting idea. Obviously you could accomplish the same thing using nested timelines and group-pre-clip, but both are a bit cumbersome. So are you thinking the “pre-timeline” group would be accessible just like the current “Timeline” group, in the node graph? I suppose that would make the most sense.

Wouldn't it make more sense to do denoising and CST at the source level within the Media Pool instead of anywhere within the timeline? Then you could have pre-Clip, clip, and post-clip grades that all apply before any in-timeline processing and those groups can be based off camera type or takes. You could even theoretically have bin-grades at that point, too.

The Pre-timeline thing feels king of weird because Timeline grades apply as a grade after the video is composited, not at the clip level. The pre-timeline grade you're proposing would would work pre-mix just like pre-clip, clip, and post-clip.

Lastly wouldn't adding grain make more sense to do in the time Timeline grade?

Absolutly. That would be the best place as this process would take place before the "Clip" nodes.

Why not but denoising at the Media Pool level would impact the preview of the rushes.

Yes, it is often the place. But sometimes, it is also interesting to denoise and add grain before the CST.
And I bet there are dozens of other interesting things that could also be pre-processed at that level.
