In a nutshell, stereo 3D Conversion is the process of making 3-dimensional imageries from 2-dimensional images. It is a laborious process that involves a range of intensive activities and frame-to-frame conversion.
Let us see what the general process of the conversion;
Most of the times, each of the shots is rotoscoped. Then these are broken down into smaller workable shapes having incredibly extensive details. As per the budgetary constraints, you can get each of the shapes into depth, which will have poorer results.
If the budget permits, you can create excellent depth maps and depth gradients, which will provide comprehensive depth map per each frame and look as the shot footage.
Following are some of the most extensively used software programs for 2D to 3D conversion;
- Dimo Video Converter Ultimate
- Movavi Video Converter
Skills and resources required for the process
Like most of the jobs and professions, 2D-to-3D conversion requires several skills and resources to get the quality that we expect. The following are the most important ones;
- Creativity: Creativity is one of the most desired skills when it comes to 2D-to-3D conversion as every project normally starts with a creative idea.
- Drawing Skills: Drawing is an important skill in 2D-to-3D conversion as you need to create blueprints for objects and items that you are working on.
- 3D Modeling Skills: 3D modeling is another important skill that a person must possess to create exceptionally detailed 3D images.
Challenges involved in 2D-to-3D conversion
While 3D in an exciting way to render a video and make it look lively, there are challenges to making it excellent. It can go out of hand if enough care is not taken.
- The parallax effect
- Time consuming
- Lack of expertise
- Singular depth resolution
These issues, as technology has progressed can be addressed to a large extent, now.
How 3D is different from normal VFX
Visual effects or VFX is the process of adding and creating imageries to a shot which is already an existing or live-shot footage. It largely involves creating structures, objects and adding elements to make a shot look more vivid and lifelike when they are practically impossible to create and shoot. This is extensively done using various creative and vfx software programs.
However, 2D-to-3D conversion is a process where the footage which is already shot in 2D is converted to 3D footage with the help of various 3D conversion techniques. The sole idea of the same to create a “pop-out” effect for people who watch the video by creating two different images on the frame for two eyes of the humans to create a sense of depth.
