Set segment duration with media convert - amazon-web-services

Question

With AWS media convert everytime I convert an mp4 (6 second video) to a dash, the segment duration is about 30 seconds however I'd much appreciate if it were 1 second or less:
<SegmentTemplate timescale="90000" duration="324000" startNumber="1"/>
<Representation id="1" width="1280" height="720" bandwidth="72000000" codecs="avc1.4d4032">
<SegmentTemplate media="5f8283b60a3ac3640191892_$Number%09d$.mp4" initialization="5f8283b60a3ac3640191892init.mp4" duration="324000" startNumber="1"/>
</Representation>
<Representation id="2" width="1920" height="1080" bandwidth="16200000" codecs="avc1.4d4029">
<SegmentTemplate media="5f8283b60a3ac3640191891_$Number%09d$.mp4" initialization="5f8283b60a3ac3640191891init.mp4" duration="324000" startNumber="1"/>
</Representation>
</AdaptationSet>
I've tried messing with the job settings, but nothing I did seemed to work. Sometimes I got it down to 10 seconds, but that still isn't great, anyway here are the settings I used:

So, in other words, what would I have to change to make my segment duration set to 1 second or less?

Answer 1

Thank you for providing the job's JSON settings for further review. Looking at the OutputGroupSettings I can see that you are specifying a SegmentLength value of 1 second so the resulting fragmented MP4 files should be about 1 second in length give or take a few frames.
How are you confirming that the resulting fMP4 files are 30 and 10 seconds respectively? The most accurate way of determining this information is to combine a variant's init MP4 with one of the fragments into a separate file and observe it using a media inspector like Mediainfo or ffprobe. I used your job settings on an MP4 file I had available to me and confirmed that the resulting MP4 segments produces are 1 second in length:
Concatenate a segment with its init file for the full MP4 asset
$ cat 5fa1ababa7cea9751765441init.mp4 >> 5fa1ababa7cea9751765441_concat.mp4 && cat 5fa1ababa7cea9751765441_000000001.mp4 >> 5fa1ababa7cea9751765441_concat.mp4
Probe the newly concatenated file to review the details
$ ffprobe -hide_banner -i 5fa1ababa7cea9751765441_concat.mp4
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '5fa1ababa7cea9751765441_concat.mp4':

I'm curious how you are confirming the resulting duration of each fMP4 asset and if you can try the above steps as well if you have not already done so.
