Video Sequence Editor Stopwatch & Timer for Blender

  • Quickly add a stopwatch or timer to your blender video
  • Count Up [Stopwatch] or Count Down [Timer]
  • Places a sequential timestamp inside of each video frame using "Text Effect" strips.
  • Encapsulates all the frames into a metastrip making it easy to select, move, and group property settings.
  • Resize it, move it, change its color, add a shadow, use it with effect strips or even animate the property settings with keyframes.
  • Script creates accurate timestamps when using integer frame rates such as 24, 25, 30, 50, 60, 120 fps. (Reason Why)

Setup

  1. Right Click on "Raw" -> "Save Link as..." on the following page:

https://github.com/mikeycal/vse-stopwatch-timer-for-blender/blob/master/vse_stopwatch_and_timer_for_blender.py

  1. Open your Blender project

  2. Set Project FPS, Start and End Frame (Script will create a timer between start and end frame)

  3. Switch an "Editor Window" to "Text Editor" by the editor type from the Editor Menu

Here is what an Editor Menu is: https://docs.blender.org/manual/en/dev/editors/

  1. Press "Open" and select "vse_stopwatch_and_timer_for_blender.py" in "Text Editor" window

  2. Press "Run Script"

Demo of Fastest way to use the script

  1. Drag it to your text editor
  2. Edit User Preferences
  3. Set Start and End Frame of the blender project (Script will create a timer between start and end frame)
  4. Run Script

Download a Source Code Editor that supports Python

At times you will need to edit this Python Script. So I would advise that you download a free Source Code editor for your platform of choice. Here are my recommendations (I use Gedit):

User Preferences

  • Simply change the values listed below to alter the size and look
  • Note: A Stopwatch counts forward [default setting]. A Timer counts in reverse - aka a countdown

Settings

  • Change timer position:
    • Right click on the Meta Strip
    • Select "Image Offset"
    • Change X or Y values

Get Font Color Values

  • Blender use RGBA floating point values. This means if you try to put in RGBA values that you got from a Color Picker online, the values won't give you the correct color. The easiest way to get the Text Color values, is to use Blender's color picker for the Text Effect Strip.

Here is how you get the color values that can be used in place of the 1's in the following script variables:

  • time_color = (1,1,1,1) [value is White]
  • shadow_color = (0,0,0,1) [value is black]
    • an example of a blender RGBA value setting would be (0,0.001,1,1) which is blue

How long should the script take to create Timestamps

(These are the results when using my INTEL i5 3570K 3.4Ghz processor)

times

  • That's right... It takes 10 1/2 hours to create 300,000 timestamps.
  • Setting put_in_meta_strip = False may improve render time, but the Metastrip is easier to manipulate in the VSE.
  • It is also important to note that Render Resolution doesn't seem to have any affect on script run time.
