My options for shooting are 1080p25 or 720p50. 1080p sure has more pixels and details but when I am downscaling to 720×576 in export, I am not sure if the difference matters. I tend to frame my shots quite carefully, so I don’t need to do that much zooming etc. in post.
Reinterlacing 50p to 50i seems to result in smoother movement than 25p to 50i, which is why I would prefer shooting with little less pixels&detail. Of course if the detail I am losing when changing from 1080p to 720p is significant even after downscaling, I must reconsider.
