A few weeks ago, our social overloads at Meta introduced the ability to send HD photos on WhatsApp. It's not full-resolution yet, but still an acceptable upgrade. The company is now extending the courtesy to videos, as well.
The next time you open WhatsApp and try to send a video, look at the top row and you will see a neat HD icon at the top. Once you tap on it, you will get an option to select HD resolution at the bottom.
If you don't pick the HD option, it will send the video in the default – and crappy – 480p resolution that turns a bald man's head into blurry jumping eggs. (That was my sorry lil joke to diffuse the tech tension here.)
But if you don't want any downscaling at all due to the compression, well, the only other option is to send those videos as a file attachment. And just like all your text messages, every poorly recorded shaky video that you send is protected by end-to-end encryption.
That means no one, except the sender and receiver in the chat, can see the chat contents. In the meantime, here's a lil tribute meme for the news. Cheers!
