Pros/Cons of DASH for short videos

[arianaa30]

Had a general question about DASH that I thought would benefit experts' thoughts:

In the standard adaptive streaming approach, like MPEG DASH, a video is available at multiple bitrates/quality levels called representations, with each representation video segmented into small chunks, like 2s durations. And the video quality switches throughout the video timeline.

Due to the maintenance and complexity of chunking, we would like to have a more relaxed version where we keep multiple representations of the video, but not chunked. So the best bitrate is selected right in the beginning, and it goes on for the rest of the video- no chunking and therefore, no switching in the middle.

Is this approach more suitable for shorter videos (< 30s)? I guess we have to implement our own player and selection logic. What criteria should we look for? Generally, I would like to know pros and cons of this approach especially for short videos.
