So its basically useless, then..? Bigger files sizes, and seems to need to be less 'realtime' i.e needs rendering earlier than HDV , when mulitple filters are applied.
Why did anyone both making it then? And why do people advise using it..?
Prores has little to do with an HDV workflow but it's hardly useless. It's designed as an editing and mastering codec coming from higher end codecs like uncompressed HD and HDCAM and from codecs that are difficult to edit natively in FCP like AVCIntra for example. Here's a little light reading on the subject:
It will help with color correction. It will put your footage into an I-Frame codec that is 10-bit...more color space and latitude than the 8-bit HDV codec. The color correction will look better, the footage won't improve.
