Working with HDV 25p

BowmanDigital wrote on 8/29/2008, 7:14 PM

I'm working on a job and am using Vegas 7 to edit footage from a sony S270P recorded in 25p compatible mode onthe camera. I think there were three modes, 50i, 1080i/25p and straight 25p.

To maintain as much quality as possible what is the file format that I should rendering to?

Also if i want to take editing footage from vegas into AE to do an effect then back into vegas whats the smartest way of doing that?

IF this is to much for a forum type response, any urls to follow up?

You might have a problem with 25p on tape as I don't know of any VCRs that'd play it. Don't even know if the S270P would record it to tape for that matter, maybe only to the CF cards. Your other option is 25PsF where the same frame as 25p is split over two fields to give 50i.
I've only done the latter with the V1P. Seemed to work a treat, Vegas recognized the flags correctly and on a 25p timeline I got 25p by the fields being merged back into frames.
25p or 25PsF will give you the highest vertical resolution at the expense of more noise and less temporal resolution. For all intents shooting 25p is the same as 24p so you will have to watch panning and tracking rates just like you were shooting film.
Also I don't know just how much vertical resolution the S270 can deliver but it could well deliver enough for you to have to wrangle issues of line twitter and aliasing as it's almost inevitable that your content will be delivered as 25PsF.

Haven't got very far into AE as yet. I did have some head scratching getting it to 'understand' 16:9 but there's heaps of good free training around and the help system is pretty good too I've found.

And regardless of all of the above. Test, test, test.

And congrats on getting the S270P. As much as I love my EX1 there's times when I'd like an S270, like when I think 4.5 hours recording on a $50 tape :)
