NCast encoders generally create only .mp4 H.264 files (a single video track, single audio track) and this is what I test with. Our lip-sync is very good to excellent (depends somewhat on the bit rate) and this is what I have been using for testing.
The workflow I use passes the file straight thru to Engage with no further conversions or processing. The lip-sync problem I noticed starts right away, from the very beginning of progressive-download playback. The file itself is only 5 minutes long. I will upload a file to MH-7700 for you to try yourself along with my workflow.
