Broadcasting from abroad is fun, but it might be cool if there is an option in mobile to embed a 1920x1080 and 1080x1920 transparent PNG with a watermark, to keep the branding almost similar to OBS on Desktop.

The fitting watermark image should be selected by detecting the landscape or portrait mode of the phone, and with preparing it for landscape or portrait the quality doesn't look stretched. Also the positioning of each graphical element is ensured to be there as planned - regardless if landscape or portrait.

As this is a local thing, the 2 PNG's are stored local, and the process is done by the Twitch Mobile Client, as part of the image process.

I think that will encourage many streamers to do IRL streams from abroad, because todays phones have good camera components, and with this feature a part of their branding is still visible.

I see this also as better option compared to for example Instagram Live, to built a community within Twitch.
