If need to post complete info,
[Chris Balogh] “I correct myself it is m2v”
what is IT, the export, the client’s need?
If the client needs a SD movie to go on a DVD, will they be doing the m2v encoding, if so what system are they on, which will determine want codec is best.
Also if your animation is truly 30 fps it will need to be retimed, DVD video has to be 29.97, not a big deal but your audio needs to be retimed to match.
