Previz Camera Tools


(tin2tin) #1

No more mess with binding cameras to markers when setting up cameras for a scene. Work in the 3D View, add the cameras to the VSE, and watch the cut-timings playback in the 3D Viewport!

Previz Camera Tools sets up the Video Editor to control the camera selection in the 3D View on frame updates. Which makes it possible to edit the clip timings on the same screen and at the same time as editing cameras and everything else in the 3D Viewport. The ambition is that people with no Blender knowledge should be able to make a mise-en-scene with this panel alone, so some native Blender functions have been moved into the panel.

Workflow Time Lapse:

Run the script

  1. Install it like any Blender add-on or run the script in the text-editor in Blender.
  2. Find the functions in the bottom of the right-hand-side menu of the 3D View.

Main Functions

  • The button “Add Camera to Sequencer” will add a scene-strip in the Sequencer with the current camera starting from the current frame.
  • The checkbox “Link Sequencer to 3D View” will link the frame number and switch cameras in the 3D View. So playing the sequencer will play the sequence in the 3D View and the camera work can be edited instantly.
  • Cycle Cameras
  • Rename Camera
  • Walk Navigation
  • Focus Length

Some more functions added and script updated(v 0.2):

This looks very promising, thanks for sharing!

Incredibly useful, thank you.
Easy to use, and powerful.

Thanks for the encouragements. I’ve added “Current Camera” and “Camera Renamer” in version 0.3:

I would love to add these functions(but I need some help to figure out how):

  • Set in and out points(of the current camera) - to be inserted at playhead in Sequencer.
  • Select Strip > Select Camera & update 3D View(select cameras through Sequencer) - as a checkbox

Thank you, I appreciate it.

New version out. This one with several native Blender camera functions inserted in the panel for easy access. Apparently, the OpenGL render in the Sequencer will have DoF rendering from next Blender release, so the DoF options are now added.

Current UI:


Btw. would “Sequencer Camera Tools” be a better name?

(tin2tin) #10

Any feedback on the latest version?

(Ethan Aeris) #11

all works fine, and the new features are appreciated.

Just for feedback, I have these messages in the console, but I don’t see bugs so far.

The cycle camera is cool, but could be improved by being replaced by a list of cameras.
Maybe the the code of “stored views” add on can help with that.
Just my 2 cents, I will not fall in the feature request complaint anymore :wink:

“Sequencer Camera Tools” seems ok, but I think that “Previz camera tools” can bring more vfx/director people to Blender.
Thanks again for your add on!

Thanks. I think I’ve now fixed errors.

A ‘Camera Selector’ is now included and the UI order has changed a bit.

(Ethan Aeris) #13

Wow, that was fast !
So far, so good, it works like a charm, no more errors in the console.
And the camera selector…Nice gift from You, Tin2tin.
Awesome, respect and I’m grateful.

(tin2tin) #14

Great! Thanks for testing it.

I’ve been thinking - would it be better to make a more simple implementation of this tool? Just in the ‘Add menu’ add Scene>Camera option and in the ‘View menu’ add checkbox+‘Update 3D View Cameras from Sequencer’?

Would it have a better chance of being added to the Blender-releases that way?

However, if the devs decide that the scene-strips should not be able to access the current scene, that would be the end of this functionality:

Cool previz example:

Thanks for sharing! Really useful!

Can I just say that Blender is a great tool for previz, even without any add-ons! We use it all the time now to previz complex movie-scenes. :cool:

I love the camera presets and the viewport performance with ambient occlusion etc!
