I just encoded some DVD content using the CLI version of handbrake and had noticed that I forgot to specify that the content was telecined. However, I've been watching the content and it looks fine, as if it were detelecined. I did a test where I specifically detelecined and, while the file wasn't identical, it was nearly identical (the file sizes were off by about 13 kB) and the image quality is, as far as I can tell, identical.
My question is: how is this possible? Does the CLI program automatically detect telecine and detelecine before encoding?
Using handbrake version 1.2.2 on Windows 10, 64 bit.
Since this is the CLI, I don't know about logs but here's the CLI output with the actual encoding removed for brevity:
