Is there a Premiere Pro plug in for HLS mp4? So that HLS (streaming) mp4 doesn't play back choppy? A Google Search brought up this result:
DPX, YUV and YUV streams are also supported as well as DASH fragmented MP4 and HLS/M3U8 h.264/ACC stream sets.

Put I couldn't figure out which plug in helps with "DASH fragmented MP4 and HLS/M3U8 h.264/ACC stream sets."
