If the results are better this way would have to be tested but the result of my initial test with deinterleaving and reinterleaving looked good and I also looked at the results on a progressive display using VLC with yadif as deinterlacer and I didn't see any artifacts when playing the file. I did not test increasing the frame rate. It may be different when doing that. Anyway, I am happy to have an additional viable option I had not thought about before.
