Hi Yejin,
Enabling "Accelerated Transcoding" would increases the processing speed of file-based video encoding jobs by up to 25 times[1]. Hence, it would reduce the transcode time. For example, if you have a 2 hours long 4K movie content, enabling "Accelerated Transcoding" would highly reduce the transcode time.
Using "Accelerated Transcoding" with a 30 sec clip would not get any benefit. Besides, you would be charged with Professional Tier [2].
If you are not transcoding any of the following content, we suggest you not to use "Accelerated Transcoding"[3]
- Ultra High Definition content
- High dynamic range content in HEVC
- Any long-duration, visually complex video
