Maya Stereo Camera Setup & Render Tutorial:

This is basic tutorial on Maya Stereo Camera Setup and render and how to Setup and render two separate views from Maya to work in a compositing software. As most of the students of Maya don’t have any Idea that how to work with Maya Stereo Camera, that's why this tutorial in Hindi to help out a big number of Indian Students. Any suggestion and quarry is always welcome, please post your comments to enrich my next tutorial.

Morphing tutorial in Nuke6.2

In this video, I am trying to show you how you can create morphing using spline warp nodes in NUKE 6.2. Nuke is for professional compositing and visual effects tool. This is the most popular software in the industry as software for postproduction section to develop high quality effects for film. Most of the production houses are using nuke in their post production pipeline to composite, develop effects and work with stereoscopy movie making and conversation. My suggestion for those people who wants to enter in postproduction pipeline, please try to upgrade yourself in nuke, as it will help to get a better job in post production pipeline smoothly.

To practice it you can plan your own footage with more interesting manner or you can also mail me for footage along with output.

Compositing example for my students, u can practice that…

In my spare time I am trying to create some example for my beloved students, just to make them habituated to brainstorm in different angel starting from very basic conception to high end conception. Start with these types of simple example, use footage and do lot of practice and make your won. Try to change the lighting, convert it from day to night etc. If u required raw footage, post your requirement, I shall upload it for you and the link I shall mail to you.

Concept of Stereoscopy Movie for game or Animation

This is a basic Concept of Stereoscopy Movie for game and Animation using Maya2011 and Nuke, I am working on that. Its not a tutorial. Within a very short span of time you can also develop these types of video using 3d software and any compositing software. You can use any compositing software to work with stereoscopy movie making process, if you have the sense of anaglyph colour comp, you can use the conception of CC and Marge (layer blend mode) to enjoy the workflow of stereoscopy. But if the available tools/nodes and options are matter then, Nuke is the best one to work with stereoscopy workflow.

Fusion Tutorial to create titling effects Example-1

In this fusion tutorial I am using fusion particle to create titling effects. Using this tutorial you can create titling effects for suspense movie and television series, you can also create title effects for your showreel and demoreel. This is very basic example, I shall try to post more effective tutorial in this section regularly.

What is Rotoscopy(Part III):

Footage for_roto_part_III_and_IV, you can download the original uncompressed footage from "Rapidshare" in two different formats. If you like to use image sequence, you can convert the .mov file to TGA format using any editing/compositing/video converter software. Due to file size, I am not uploading TGA format in rapidshare.

To make a cut-out or matte of any character or object from a scene we use rotoscopy. Rotoscopy is also useful for image enhancement; like Color correction, color change, gradation etc. Once the animated matte is developed for any part of the scene through rotoscopy, now you can use it for different purpose. For example: In this scene if you like to create matte for the character, chair and table to change the BG I am creating 8 polygon shapes. How many polygon shapes you have to create, that totally depends on requirement of compositing section, and it will be designed by the TL or Production Head. You can also use combined technique of keying and rotoscopy together. But the keying process is not useful for Stereoscopy conversation (I shall describe further). In this example I shall only use polygon shape.
Before starting the creation of polygon shape, always play the footage several times to get the movement details of character/objects, due to camera movement any object will change the shape, in particular scene. In this example camera is fixed, so one polygon shape is good enough to cut the Table from scene. No animation is required for this shape also. But due to the activities of character, chair is moving, so I need animated polygon shape for character and chair both. Now, maximum movements are in right hand of the character. But in this example I do not required a separate polygon shape for right hand, because its moving inside of body line in front of camera. So in that case nothing to worry due to the maximum movement of right hand, it will consider inside of same polygon shape which I shall create for body. But remember, it will be complicated when I shall use the same footage for stereoscopy conversation (I shall describe it in my next article).

Create all the roto shapes one by. In this example most of the shapes was created at frame number one. And animated in an interval of 16 frames. Check the image bellow, key interval for roto shape 1 in stage 1.

In next step you have to animate the shape in a key interval of 8 frames. Check the image bellow, key interval for roto shape 1 after stage 2.

In this way I animate all the roto shapes. After stage 5 I found that, I am able to complete the animation of all roto shapes for each and every frame. If you follow the same procedure, within a very short span of time you can animate all the roto shapes for every frame with highest amount of perfection.
Stage 3:

Stage 4:

After stage 4, I found that, if I continue the same process; after stage the polygon shape will animate for each every frame perfectly. Sometime it may happen that, the animation is not required for each and every frame. But few production houses like to use frame by frame animation and this habit is also useful for stereoscopy movie conversation. One more thing, in this example I am using soft edge for the polygon shape (value: 0.0005) but in case of stereoscopy movie conversation you can’t use soft edge, this pipeline needs précised polygon shape. When you are using roto shape for hair, you have to remember that hairstyle is important for a character; production may ask you to roto all the hair lines. If production is not asking for that, then you have to maintain the shape of the hair which is carrying the characterization of the character. In black n white format if you get the character that it is actually, then your rotoscopy is ok.
Rotoscopy is a time killing process and needs lots of passions to complete rotoscopy for any complicated scene. For a vfx composition, rotoscopy is must; so a compositor can’t avoid rotoscopy. But smart compositor use different techniques to create animated mask for a scene. Like combination of color suppress, keying, 2D tracking etc. Production houses are using few software dedicated for rotoscopy like “Silhouette”. If you know the rotoscopy process in “Fusion”, “Shake”, “Nuke” etc you can upgrade yourself in rotoscopy, within a very short span of time for any new software.
