Which res, best workflow?
Moo!
I was just checking the Cow’s Tape Formats Storage Requirements chart from May 2006 that I printed out to see how much drive space I’m going to need for an upcoming project. It says that both HDV and DV25 require the same amount of space, 11.25GB per hour. But it looks like an Avid oriented list. Does this hold true for FC and is it still the same now in 2008?
I have 20 PAL HDV tapes and I am trying to determine what the storage requirements are so I can decide whether to capture to PAL HDV, PAL DV25 (doesn’t seem to make much sense if it doesn’t save space over HDV?). And it doesn’t make any sense to go to ProRes422 does it? That’s for if footage was at higher res than HDV, right? (I’m new from Avid)
I am also looking for the absolute cheapest workflow. I figured I’d edit in PAL. But 2 things I don’t know yet. I will need an NTSC finished broadcast (PBS) master. How do I get there from here. Can FC convert it upon output? Can it up convert it to HDCam or other higher res if needed for PBS?
Also, due to being shot with a 35mm adaptor, the image is upside down.
Am I crazy to think I can deal with this by using the vertical flop effect on all the footage (thereby creating new subclips?). Will they need to be rendered before I start cutting? Will they cause problems with matchframing? Any suggestions would be most appreciated. -

HDV and DV take up roughly the same amount of HD space. DV PAL runs at 3.6mb/sec and HDV takes up slightly less space. HDV is heavily compressed therefore the small storage size.
Check out AJA’s data rate calculator: https://www.versiontracker.com/dyn/moreinfo/macosx/25717If you’re so inclined, you can change the timeline compression settings of your HDV footage to ProRes when you start the edit, as this is a much more friendly format for colour correction, graphics, comping etc.. But will take up a lot more space. It isn’t recommended to edit in HDV if you can avoid it.
Are your deliverables NTSC only? If so, why not shoot HDV 1080i 60. This way, your frame rate is already set up for NTSC delivery. If you want to stay in PAL land and shoot HDV 1080i 50 then you can do the standards conversion through Compressor, on the timeline in FCP or with a plugin Like Graeme Nattress’ Standards Converter for FCP. My suggestion would be the latter. Graeme’s converter does a great job, and from experience, takes a fraction of the time that Compressor would take, if you set Compressor to the highest settings.
Upside down footage is a real bugger isn’t it? I had to go through the same process with a short film I just finished editing.
I flipped the footage, created subclips, exported and imported again, as I was eventually heading into Color for grading and the flop filter doesn’t get sent to Color when using the “Send to” command in FCP. If you follow this method, Match Frame will only link to your new imported clips. If you aren’t concerned about the Color workflow and work from the subclips, match frame will still reference the upside down Masterclips.Cheers,

I checked out the calculator but it doesn’t have ProRes422 to see how much storage space I would need if I converted my HDV to it.

The tapes are already shot (in PAL). When you talk about converting to NTSC via these various methods, you are talking about the finished edit not the raw tapes, right? That was my plan.

Yep, i was talking about converting your finished project from PAL to NTSC. Converting the rushes to NTSC would reduce the quality even further, and would take a long time. I wouldn’t suggest doing that!!
