Introduction
This article discusses the concept of reusing outputs in complex queries, with a focus on 3D SBS video (stereo 3D) split whole... We'll cover key concepts, provide examples, and offer guidance on best practices.
Understanding 3D SBS Video
Side-by-side (SBS) 3D video is a popular format for delivering stereo 3D content. It consists of two separate video streams, each containing half of the overall image, positioned side by side.
Example of SBS 3D Video
Consider a 1920x1080 video, where the left and right video streams are each 960 pixels wide. The left stream would contain the left half of the image (0-959 pixels), and the right stream would contain the right half (960-1919 pixels).
Splitting Whole 3D SBS Video
Splitting a whole 3D SBS video into its left and right components can be achieved using various tools and programming languages. Here's a Python example using the FFmpeg library:
Python Code for Splitting 3D SBS Video
import ffmpeg
input_file = "input_3d_sbs.mp4"
output_left_file = "left_stream.mp4"
output_right_file = "right_stream.mp4"
(
ffmpeg
.input(input_file)
.filter("format_streams", format="yuv420p", force_key_frames="express")
.filter("hflip", force_key_frames="express")
.output(output_left_file, vframes=None, s=None, acodec="copy", aformat="aac")
.output(output_right_file, vframes=None, s=None, acodec="copy", aformat="aac")
.run()
