In the case that you know from the begining that the output has to be 720p, at wich stage would you consider to downsample the footage at 720?
Normaly I film at the max res posible, convert into editing format at the same res, edit, keep a master and from the master I create the necesary versions.
But I was thinking if it would be a good idea to downsample at 720 directly from the convertion to editing format. This has the advantage to be less memory consuming. But I'm not sure if quality is lost this way.
So, reducing at 720 from the begining or at the end after the editing?
