I'm looking mediaconvert service from aws to transcode videos. The value I'm trying to set just now is quality level (QL) for QVBR, according with this it could depends on the platform, for example for 720p/1080p resolution it proposes QL=8/9 (for TV), QL=7 (for tablet), QL=6 (for smartphone).
In fact, the app have a version for the 3 type of devices then I'm asking: I need to keep 3 versions for the same video? I want to save some money in streaming and my app has similar number of users using it in each platform, I want to save in bandwidth but providing good quality videos
