I have switched companies for a while, while in my last company we where using Fusion for compositing, in the new one we are using Blender.

I find it a bit hard to transition because of 2 main reasons:

  1. The nodes look very messy because of all the squiggly lines and its sometimes hard to follow a path naturally.

The most important one:

  1. Once you start adding a couple of nodes it becomes really slow, it seems to always be compositing something, if I move a node, it composites, if I make changes to a node that doesn't affect the final image, it composites. I like using the software but it can become very annoying.

    $\begingroup$ It shouldn't composite if a node was only moved. It will if value in node's field was changed (if you made a field active and don't want to apply changes press Esc). $\endgroup$

  1. You can change the lines to be straight by going to "File > User Preferences > Themes > Node Editor > Noodle Curving".

  1. You can disable "Use Nodes" to keep it from updating until you are done moving.

To speed up things a bit you can tweak the performance options on the node editor (press N to make them visible on the right side of the screen).

enter image description here

Bring down the quality for edit, use OpenCL and adjust the chunksize.

Additionally you can use border rendering, to render only a small portion of the image (like you'd use the "region of interest" in fusion). On the UV/Image editor press CtrlB and click and drag to draw a rectangle around the area you want to visualize. Blender will render only that area if the view border option is checked.

Use the node wrangler plugin, it has a lot of shortcuts to connect and replace nodes. Read this link for more info: http://gregzaal.github.io/node-wrangler/

    $\begingroup$ I will add that node wrangler is included with Blender now :-) $\endgroup$

    $\begingroup$ The biggest drawback on using blender's compositor is that there is no way to preview the scene in real time. Blender does not have a playback buffer (like Fusion, Natron, nuke or even afterFX) So you only see what you are doing when you render.... $\endgroup$

  • $\begingroup$ @cegaton If Blender could get a playback buffer, it would be incredible. Would that be an appropriate feature request? $\endgroup$

  • $\begingroup$ @AnsonSavage I would not hold my breath for that to be implemented any time soon. There are a number of specialized compositing apps available that do a much better job. Try using Fusion or Natron (both free) or even Nuke.. $\endgroup$
