Record Video in 720p Instead of 1080i

0 Comments


Most of the people think that video in 1080i quality is better then 720p ,and this because most of them think that 1080i is bigger number or they mix up 1080i and 1080p.
In reality there is a huge difference between 1080i and 1080p or 720p.The alphabet "i" means  interlaced video and if this is 1080i ,it means interlaced video in 1080i mode. Now the second one is "p" that means progressive,this video quality make video in progressive video quality(explained below).
When we deal with interlaced video,the viewer actually saw the half resolution because the video frame is divided in two fields,one is even and other is odd field.Both together make a frame that we call the interlaced frame.This video technique was useful in early days when there were bandwidth limitations.But now with help of  new technology we can see Full image in single frame with high quality i:e 720p and 1080p.
Now the question is How 720p works ? Answer is quite simple,In 720p there are 720 horizontal lines in each frame but in 1080i ,you only see half of the line that are 540 lines.So this means 720p is better then 1080i.In interlaced resolution when object is moving fast and if you abruptly stop the video,you will see the fast moving object looks is smearing across the screen instead of looking natural.
This is the sequence of high Resolution
1080p
720p
1080i
480p
480i
and others...

The Art of Motion Capture

0 Comments

Motion Capture is the process of recording movement and translating that movement on to a digital model Usually used in military, entertainment, sports, and medical applications, and for validation of computer vision and robotics and mostly in filmmaking. 




You need Supercomputers For Rendering 
Thousands of processor to run 
Hundred of Visual experts Required 
petabyte of Storage Required


In films Camera movements can also be motion captured so that a virtual camera in the scene will pan, tilt, or dolly around the stage driven by a camera operator while the actor is performing, and the motion capture system can capture the camera and props as well as the actor's performance.A computer processes the data and displays the movements of the actor, providing the desired camera positions in terms of objects in the set. Retroactively obtaining camera movement data from the captured footage is known as match moving or camera tracking.

3D Motion capture provide following advantages:
Tracking Cameras
More rapid, even real time results can be obtained. In entertainment applications this can reduce the costs of keyframe-based animation. For example: Hand Over.
The amount of work does not vary with the complexity or length of the performance to the same degree as when using traditional techniques. This allows many tests to be done with different styles or deliveries.
Complex movement and realistic physical interactions such as secondary motions, weight and exchange of forces can be easily recreated in a physically accurate manner.
The amount of animation data that can be produced within a given time is extremely large when compared to traditional animation techniques. This contributes to both cost effectiveness and meeting production deadlines.
Potential for free software and third party solutions reducing its costs.

Avatar
Movie avatar is best example of Motion Capture and Visual effects.The lead visual effects company was Weta Digital in Wellington, New Zealand, at one point employing 900 people to work on the film. Because of the huge amount of data which needed to be stored, cataloged and available for everybody involved, even on the other side of the world, a new cloud computing and Digital Asset Management (DAM) system named Gaia was created by Microsoft especially for Avatar, which allowed the crews to keep track of and 

                                     
coordinate all stages in the digital processing. To render Avatar, Weta used a 10,000 sq ft (930 m2) server farm making use of 4,000 Hewlett-Packard servers with 35,000 processor cores running Ubuntu Linux and the Grid Engine cluster manager.The render farm occupies the 193rd to 197th spots in the TOP500 list of the world's most powerful supercomputers. A new texturing and paint software system called Mari, was developed by The Foundry in cooperation with Weta.Creating the Na'vi characters and the virtual world of Pandora required over a petabyte of digital storage, and each minute of the final footage for Avatar occupies 17.28 gigabytes of storage. To help finish preparing the special effects sequences on time, a number of other companies were brought on board, including Industrial Light & Magic, which worked alongside Weta Digital to create the battle sequences. ILM was responsible for the visual effects for many of the film's specialized vehicles and devised a new way to make CGI explosions. Joe Letteri was the film's visual effects general supervisor.
For High Precision Motion Tracing
At first glance, 3D animation movies seem a longshot to be created independently. With the complexity of animation, it seems a given that it should be created within the bounds of a 3D animation studio. If these studios take years to create a full-length feature, how about an independent filmmaker? 



Camera Tracking Architecture

From optical/inertial, to encoded systems, to motion capture stages, to GPS/IMU outdoor tracking, Previzion can handle nearly any form of tracking device

Optical/Inertial. For Ultimate Tracking Flexibility.

The fusion of the Intersense IS1200 optical tracking camera and the Lightcraft Airtrack electronic gyro provides tracking for the broadest range of shots. From handheld and Steadicam, to dolly, jib, and Technocrane shots, this can handle nearly everything.
Using targets mounted overhead in the stage truss, a standard stage can be converted into a real time capable smart stage in a single day.
Recommended Softwares for motion capture effects are  Adobe premiere pro, After effects, Sony vegas,Syntheye and many more.
