I knew switching my cameras to HD would mean editing would take longer than NTSC. However I've read some tutorials and there were some quick mentions of cutting your footage in SD and referencing your HD footage using the media manager on output. I'd like to find more info on how to do this but haven't come across anything in depth. Does anyone else have any reference material that pertains to this type of editing? And/or what are the pros and cons to this workflow? Sounds like if you have a large project in HD, this would speed things along.
