I use Blender as a video editing program and I recently started colour grading my material. Now my computer is pretty slow, for now and I want to upgrade, but I won't use Node-editor for now, so I colorgrade directly through strip-modifiers, because even with identical effects via compositor-nodes vs strip modifiers, the latter always renders faster (around factor 2-1.5). BUT, there's a big problem: In strip modifiers I can only use the histograms that the Video Sequence Editor is offering me, which are lackluster and bad. In UV image editor, via tool shelf, I have WAY better and more accurate visualizations. I have found no way to load a strip from the sequencer in UV image editing. Is there a way? Also, either histograms always get very "spikey" as soon as even the slightest modifications are applied.

On another note, why does using scene strips from Compositor eat up so much more processing power than using video clips directly, EVEN IF the node editor doesn't actually apply any changes?

And finally: I currently have a GTX660 and a 3.75Ghz Intel and want to upgrade to a better Graphics Card. I really DON'T want to stick with Geforce. What's a good card on a 300-400€ budget that will give me decent rendering power for 4k videos? Currently render 30 frames per minute, while normal FHD 1080p material does 130-210 frames per minute with equivalent modifications.

  • $\begingroup$ Welcome to BSE! Wow, good questions. That is a bit of an issue though; questions. On BSE, you're supposed to only ask one question per post. I would recommend moving the second paragraph's question to a new post, and the third paragraphs question to a non-Q&A forum like a BlenderArtists where you will get better answers. $\endgroup$ – Shady Puck Jun 21 '16 at 2:21
  • $\begingroup$ It's more like a workaround, but if you render with Compositing nodes turned off, you should get result from VSE, which can be previewed and investigated in the UV / Image Editor as any image. $\endgroup$ – Mr Zak Jun 21 '16 at 9:57
  • $\begingroup$ OKay, thanks, But how do I introduce VSE images into as an image? is it an addon? It doesn't work via Render-Result. $\endgroup$ – Keen Gaze Jun 21 '16 at 11:31
  • $\begingroup$ By default, when rendering with VSE turned on and compositing nodes turned off, the rendered image will be the result came from VSE. Probably in your file VSE isn't used to affect on the render result. See how to choose where to render from, VSE or camera. Generally, result from VSE should've already been in rendered result in your case. $\endgroup$ – Mr Zak Jun 21 '16 at 12:08
