So may be you need more complex hdv interlaced = to frames -> scale down fields independently = > encode procedure .... https://cinelerra-gg.org/download/CinelerraGG_Manual/480.html If you just deinterlace then scale it will be simpler, i think. Because we not start with upscaled interlaced SD ....
