Cannot get high quality for video

After uploading the assets if I try to fetch a high res mp4 url i get null .

Even if i change the url for low res mp4 (ending in low.mp4) to (high.mp4) i get 404 from mux. Do i have to enable high res streaming from settings?

Hello @apoorv.kansal

This is due to the resolution of the source video, as documented here by MUX: Enable static MP4 renditions | Mux
Your initial resolution seems to be 480p and you need to have at least an original resolution of 720p for the other options to be available
