Raster To Video (Conversion)
Summary
Creates a video file from a set of images.
Usage
- When creating a video from images in a folder, make sure that the folder specified has more than one image file of the same type (BMP or JPEG).
- This tool reads the images in the folder in alphabetical order. The output video will contain frames in the order the images were read from the disk.
-
Keeping in mind that the images are read alphabetically, you can insert images in the folder of images such as a title image for your video. For example, if the folder of images has images with names image_1.bmp, image_2.bmp, and image_20.bmp, you can add an image named _image_1.bmp. Since the tool reads the images in an alphabetical order,_image_1.bmp will appear before image_1.bmp in the output video.
-
The resolution (width x height) of the output video is based on the resolution of the first image in the folder of images supplied to the tool. If the first image has a smaller or larger resolution than the others, the rest of the images will be stretched to fit the resolution of the first image. So try to keep the resolution of the images in the folder consistent.
-
Since AVI and QuickTime formats are supported on Windows only, this tool will not work on a non-Windows platform.
