| YouTube, as well as any decent player, plays any aspect ratio video, even portrait mode. As an uploader you should never add black bars (if they are in the source, crop them out before uploading) and of course never distort the video. This ensures the best playback experience for all devices. |

In practice, the YouTube layout looks weird on aspect ratios that aren't 4:3 or 16:9. If you upload any vertical video it gets categorized as a short, so that's out of the window - and even for things like 21:9 you get a teeny tiny player on desktop since it just fits the width. | |
| ▲ | sigmoid10 40 minutes ago | parent | prev | next [-] | | Ah yes, the good old "shot in portrait mode, converted to 16:9 with added black bars, and then displayed under YT shorts in portrait mode again" category on youtube. This is almost artistic at this point. Sometimes I wonder how small can the content of a video get before people will stop watching it. Is there any research on this? | |

| You can. I've even seen intentional 4:3 used as an "80s" signifier. Quick googling suggested that square video under 3 minutes will be automatically classed as "shorts", which much of HN hates and may never have seen. |

| AFAIK youtube will stretch the player window to match the aspect ratio of the source media, lots of cinematic content that's a wider than normal (21:9 I think?) ratio that youtube adjusts the player window to fit around without black bars. They won't ever squash or stretch video though, so this means the original uploader stretched the 4:3 content to 16:9 at some point before upload |

| I think it will show in whatever aspect ratio you upload. It cares about overall pixel size, and for example standard 720x576 standard def 4:3 video will be brutally compressed compared to the exact same video upscaled using any non-AI upscaler (even nearest-neighbour) to 1440x1080. I dug into this a bit a while ago, and could probably post my finding here if anyone was interested. |
