Triton auto-tunes BLOCK_SIZE: different sizes optimize for different hardware
Ever wondered why videos look different on various devices?
Imagine you're streaming a movie on your phone, tablet, and smart TV. The movie looks great on your TV but stutters on your phone. Why does this happen?
It's because each device compresses the movie differently to save space. The trick is to find the perfect balance between quality and file size for each device.
Example
On your phone, the movie is compressed to a smaller size, making it faster to stream but less detailed.
Remember this
Different compression settings, or BLOCK_SIZE, optimize video quality for each device's hardware capabilities.
