I guess it does fit the definition of the term. The industry decided to call the 16:9 widescreen DVDs "anamorphic". As 16:9 DVDs became more mainstream, widescreen images were also placed on them by adding black borders top and bottom. Back in the dark ages, when most DVDs were 4:3, widesceen images were placed on them by adding black borders top and bottom. ie aspect ratios which exceed 16.9 and must be letter boxed appropriately to display as accurately as possible. In reality some blu rays are anamorphic, just in the reverse of DVD (2.x and above). The interesting thing is, I have seen some posts about blu ray not being anamorphic. Using anamorphic loose with a modulus of 2 could potentially make it even a tad more accurate of your player supports anamorphic video. If you just resize with anamorphic none and a modulus of 2 using Handbrake though, the resizing will still be pretty accurate. I resize everything to square pixels myself, but I use a calculator such as this one to adjust the cropping and resizing for minimum aspect ratio distortion. ![]() With anamorphic loose they can be slightly different. It's only when you resize the result might be slightly different, as with anamorphic none the output resolution and display aspect ratio are always the same. The output video would have the same pixel aspect ratio as the input video (it always does for anamorphic strict as it doesn't allow you to resize). For example if you resized that same 1280x720 video to 1278x720, Handbrake would probably still show 1280x720 as the display size because it's adjusted the pixel aspect ratio a tiny bit so the display aspect ratio remains unchanged.Īnyway, if you don't resize, and the source video is not anamorphic, "anamorphic none" and "anamorphic loose" with a modulus of two should result in exactly the same output. When you use anamorphic "loose" and you resize, Handbrake can adjust the pixel aspect ratio to keep the display aspect ratio a little more accurate (effectively it's adjusting the display aspect ratio). If you open a video (as an example) with 1280x720 dimensions and resized it to 1278x720, the picture would end up squished a tiny bit. The resolution and display aspect ratio are one and the same. Or the output video always has a pixel aspect ratio of 1:1. ![]() Anamorphic "none" always resizes the video to "square pixels".
