Image strips can display thumbnails in the Sequencer overlaid on their strips by enabling the Thumbnails overlay.
When you add a single still image (
Blender creates a 25 frames long strip which will show this image along the strips range.
In the case of (numbered) image sequences
*-0003.jpg, etc, of any image format), you have a choice:
Navigate into the directory and LMB click and drag over a range of names to highlight multiple files. You can page down and continue Shift-LMB click-dragging to add more to the selection.
Shift-LMB click selected non-related stills for batch processing; each image will be one frame, in sort order, and can be a mix of file types (
Press A to select/deselect all files in the directory.
Dealing with Different Sizes
Dealing with different sized images and different sized outputs is tricky. If you have a mismatch between the size of the input image and the render output size, the Video Sequencer will try to auto-scale the image to fit it entirely in the output. This may result in clipping. If you do not want that, use Crop and/or Offset in the Input panel to move and select a region of the image within the output. When you use Crop or Offset, the auto-scaling will be disabled and you can manually re-scale by adding the Transform effect.
Add Image Strip
- Relative Path
Store the location of the image file relative to the blend-file.
- Start Frame
The Start Frame to place the left handle of the strip.
- End Frame
The end frame to place the right handle of the strip.
Subtract the Start Frame from the End Frame to get the strip's duration.
The Channel to place the strip.
- Replace Selection
Replaces the currently selected strips with the new strip.
- Fit Method
Determines how images with an aspect ratio different than the scene's Resolution are scaled to fit inside the render area.
- Scale to Fit
This may mean that the transparent areas may be added along the content's border to fit the content in the rendered area.
- Scale to Fill
This may mean that portions of the original image no longer fit the content inside the rendered area.
- Stretch to Fill
Adjusts the strips Scale Transforms so the visual contents of the strip to fill the project's Resolution. Note, unlike the other two methods described above, Stretch to Fill does not maintaining the original aspect ratio.
This may mean that the original image becomes distorted to fit the content inside the rendered area.
- Set View Transform
Automatically sets an appropriate View Transform based on the Color Space of the imported media. In most cases, the Standard should be used; using the wrong transform could result in inaccurate colors or degraded rendering performance.
- Use Placeholders
Image sequences can use placeholder files. This works by enabling Use Placeholders checkbox when adding an image strip. The option detects the frame range of opened images using Blender's frame naming scheme (
filename + frame number + .extension) and makes an image sequence with all files in between even if they are missing. This allows you to render an image sequence with a few frames missing and still the image strip will have the correct range to account for the missing frames displayed as black.
When the missing frames are rendered or placed in the same folder, you can refresh the Sequencer and get the missing frames in the strip. The option is also available when using the Change Data/File operator and allows you to add more images to the range.
