I have an animation of which I want to render specific frame ranges, such as frames 100 through 340 and frames 765 through 1092.
I saw on another Blender StackExchange question that you can render specific individual frames with the command line, but I need to render frame ranges.
Is there any way to do this?
Command line render options
Remder options displayed by running blender --help in the system console
Render Options:
-b or --background
Run in background (often used for UI-less rendering).
-a or --render-anim
Render frames from start to end (inclusive).
-S or --scene <name>
Set the active scene <name> for rendering.
-f or --render-frame <frame>
Render frame <frame> and save it.
* +<frame> start frame relative, -<frame> end frame relative.
* A comma separated list of frames can also be used (no spaces).
* A range of frames can be expressed using '..' separator between the first and last frames (inclusive).
-s or --frame-start <frame>
Set start to frame <frame>, supports +/- for relative frames too.
-e or --frame-end <frame>
Set end to frame <frame>, supports +/- for relative frames too.
-j or --frame-jump <frames>
Set number of frames to step forward after each rendered frame.
-o or --render-output <path>
Set the render path and file name.
Use '//' at the start of the path to render relative to the blend-file.
The '#' characters are replaced by the frame number, and used to define zero padding.
* 'ani_##_test.png' becomes 'ani_01_test.png'
* 'test-######.png' becomes 'test-000001.png'
When the filename does not contain '#', The suffix '####' is added to the filename.
The frame number will be added at the end of the filename, eg:
# blender -b foobar.blend -o //render_ -F PNG -x 1 -a
'//render_' becomes '//render_####', writing frames as '//render_0001.png'
-E or --engine <engine>
Specify the render engine.
Use -E help to list available engines.
-t or --threads <threads>
Use amount of <threads> for rendering and other operations
[1-1024], 0 for systems processor count.
The following command renders (render animation) frames 1 to 4, then 10 to 11 of file scripttest.blend
blender -b some.blend -s 1 -e 4 -a -s 10 -e 11 -a
To render every nth frame set the jump value. Following command renders every second frame of first hundred, every third frame of second hundred frams
blender -b some.blend -s 1 -e 100 -j 2 -a -s 101 -e 200 -j 3 -a
Blender has many command line options, the two you are looking for are --frame-start and --frame-end (short versions are -s and -e).
blender -b myanimation.blend -s 100 -e 250
You can always see blenders cli options with blender --help
