But earlier films were presented in a 4:3 ratio.
Since the introduction of widescreen HDTV and 4K Ultra HD TV, aspect ratio has been standardized with the 16×9 aspect ratio.

Also, it will help to reduce the blank space around the picture.īecause the majority of today's TV shows use the aspect ratio of 16:9, so 16:9 works great for TVs. With a certain aspect ratio, TV device can better handle video contents and resolutions without any stretching or distortion of the picture. Today, all smart TVs sold on the market have a standard aspect ratio of 16:9. W refers to the width, and H is the height. In general, TV aspect ratio presented as W:H like 16:9, 4:3, or 21:9. 9090909… so these settings should be correct.TV aspect ratio is the ratio of width to height of the TV screen. 9, and dividing Blender’s NTSC setting’s AspX 10 by AspY of 11 yields. Blender apparently has an aspect ratio already set for letterboxed PAL which, if I interpolate those settings correctly, is an aspect ratio of 1.42, which is corret for PAL letterboxed 16:9.įor NTSC 16:9, you need to set the aspect ratio to 1.2, which I’m interpolating as setting AspX to 12 and AspY to 10. If you’re rendering for letterboxed standard video, then you need to set your setting for either standard NTSC or PAL. I’m not sure if aspect ratios change for interlaced HDV or HiDef, they may. What medium are you rendering for? Are you rendering for HDV, HiDef or do you want to letterbox in standard definition?įor HiDef, if you’re rendering for HDV, your res should be 1280x1024 progressive or interlaced, for HiDef video you should be at 1920x1080 interlaced. Hitting the “PC” button in Blender brings these Asp numbers to 100 XY, so I would leave it at that and render at your 16:9 res. "AspX, “AspY”), but … will that in fact address the concern I’ve raised here? <<Īlthough I haven’t read up on how the AspX,Y settings relate to aspect ratios (I will assume they indeed are the aspect ratios), what you’re looking for should be an aspect ratio of 1. >Maybe I simply don’t grok what the “SizeX, SizeY” options are supposed to do (vs. (Show of hands, please? See, I’m not alone!) Can anyone recommend a particularly good web-site? The documentation here is extremely sketchy to me because my conceptual understanding of these issues is also, well, extremely sketchy. Indeed I am generating “pre-distorted images which look bad on a computer.” I am given to understand %| that, at the moment at least, “this is a necessary evil.” I’m wondering how long this must be so. TV screens do not have the square pixels which Computer monitors have, their pixels are somewhat rectangular, so it is necessary to generate pre-distorted images which will look bad on a computer but which will display nicely on a TV set. The Blender documntation ( ) says in pertinent part: I cannot change the output parameters in such a way that makes it look right on my computer monitor, if in so doing I alter what will appear on the TV monitor in my final kiosk installation. I need for the aspect-ratio and image-size to be "correct for DVD output to a flatscreen (I think they call it “EDTV?”) monitor. "AspX, “AspY”), but … will that in fact address the concern I’ve raised here? Not so fast… Maybe I simply don’t grok what the “SizeX, SizeY” options are supposed to do (vs. Hope this works for you, it does for me, and everyone else…
