I just realized an issue with all of the 60i footage shot by my HMC150, then converted to Cineform. The temporal quality of the transcoded clips are entirely wrong.. smooth pans in the original 60i MTS turns to a nasty stutter..

My setting for conversion is:

quality: medium
output frame format: Maintain frame format

Everything else unchecked..

Any ideas? The original footage was captured in HMC's HE mode

I should add that the 60i footage was shot in one of HMC's lower datarate mode HE which is (1440x1280)

Check in a tool like Virtual Dub, sometimes this is just a graphics card display issue, not correctly handling the fields.
