FFmpeg is a great tool to have in your toolbox if you’re a multimedia geek. If you live mostly in the world of Microsoft Windows and have dozens, hundreds, or thousands of files to process though they lose a little luster. Sure, there are tons of free applications built on FFmpeg that provide some limited batch processing capability, but usually they're just that; limited. Here’s a simple way you can process hundreds of files from one format to another, using the full capability of your FFmpeg install.
First, which scripting languages do you know? Great, we won’t need those, but that’s really cool that you know them. Given that you’re reading this, I’m going to assume you can write plain text into a text file. I don’t like to assume anything, but I’m feeling pretty good about that one. Alright, let’s get started.
Understanding video standards is fundamental to aspect ratio correction. Back in the predominantly analog days we had three main standards referenced or used for most video recordings; NTSC, PAL, and SECAM. Then in the early ‘90’s came the first digital multimedia frameworks to reach the average consumer; QuickTime and, shortly thereafter, Video for Windows (VfW).
Today we have dozens of multimedia frameworks, digital video and digital display standards, all of which lead to a great deal of confusion regarding the plethora of acronyms and what they truly mean. AVC or H.264? HEVC or H.265? CIF or SIF? Don’t even get me started on the profiles and parameters available for each standard, as the combinations are truly mindboggling. When it comes to proper Display Aspect Ratio (DAR) though, it really boils down to “Are the originally recorded pixels square or non-square?”
