2.35:1 Cinemascope (Anamorphic) Aspect Ratio Tutorial

by Michael on August 29, 2011 in Tutorial, Video with 4 Comments

A 90 second tutorial on exporting 1080p widescreen (16:9) footage to Cinemascope aspect ratio (otherwise known as Panavision or Anamorphic Scope – 2.35:1 ratio).

In this example, I used 100 pixels on the top and bottom. TRUE 2.35:1 aspect ratio would be 132px on top, and 131px on bottom (or vice versa). The final output would be 817px tall.

☞ ASPECT RATIO CONVERSION METHOD:

To convert from any aspect ratio to a wider format (such as 2.35:1 or 1.85:1), all you have to do is

DIVIDE the WIDTH of your SOURCE footage (1920 in this example) by the final aspect ratio desired (2.35 in this example).

So,
1920
DIVIDED BY
2.35 = 817 pixels tall

Your final output would be 1920×817.

✏ To find the amount to crop off the top and bottom, subtract your pixel number (817px here) from your source footage height (1080px) and divide it by two. If it is a decimal number (such as 131.5), even it out to whole pixels (i.e. – crop 132px from top, 131px from bottom).

✏ Here are some examples of aspect ratio conversion methods. These are all assuming 1920×1080 footage. If your SOURCE footage is 1280×720, your width would be 1280; if your SOURCE footage is 720×480, your width would be 720; and so on.

☞ 16:9 to 2.35:1 / Cinemascope / Anamorphic / Panavision Aspect Ratio:
SOURCE footage width (1920) DIVIDED BY 2.35 = 817px tall
Crop 132px off top, 131px off bottom.

☞ 16:9 to 1.85:1 / Academy Flat / “Flat” Aspect Ratio:
SOURCE footage width (1920) DIVIDED BY 1.85 = 1038px tall
Crop 21px off top, 21px off bottom.

As a ‘bonus’, here is the method for converting your 4:3 aspect ratio video to regular 16:9 widescreen (assuming 640×480 footage):

☞ 4:3 to 16:9 Regular Widescreen Aspect Ratio:
SOURCE footage width (640) DIVIDED BY 1.778 = 360px tall
Crop 60px off top, 60px off bottom.

How to Color Correct in After Effects (The RIGHT Way!)

by Michael on March 31, 2011 in Tutorial, Video with 7 Comments

An in-depth tutorial on color correction using Curves inside of After Effects and Photoshop.

This method explains how to color correct most any footage “by the numbers”. It’s a bit of a science that requires only a minimum amount of understanding of RGB values.

You can skip the introduction if you so choose:
0:45 – Before and After
1:09 – Tutorial Start
12:37 – Edit your color corrected footage in Premiere! (Dynamically Link the CC’ed Footage)

Using Photoshop for color correction is really a lot easier than you may think. In this tutorial, the method is very simple and fast – NO rendering multiple frames, NO importing video files into Photoshop, and easy access to making color changes.

This tutorial is a tad long at 15 minutes – please bear with me as I fully explain the techniques here! :) Hopefully you will find the techniques helpful.

☞ TIPS:

✏ Choose areas that are large enough to sample and don’t contain color casts or Chromatic Aberration
✏ Remember to use common sense. If the colors are just not looking right, either sample a different area or adjust to your liking.
✏ Your footage may have different areas of brightness or color shifts throughout the video. Animate your Levels for differing brightness, and animate your Curves for differing color where needed.
✏ Sometimes having crushed blacks or blown highlights are okay – especially in video. Keep this in mind when working with the Levels effect and don’t worry if you have either of those in your final result.
✏ If you have the opportunity, use a gray card somewhere in the image – so that later in post, you can reference that neutral gray midtone for color correction.
✏ IMPORTANT: If you are using CS5, make sure you are using the Eyedropper Tool, NOT the Color Sampler Tool. Thanks to Ryan Yakich for the heads up.
