Using this workflow you're totally reliant on timecode.
As far as I know HDV and TC is a bust. How much of that is Vegas's fault and how much of that is due to the nature of HDV I don't really know.
I used to believe this wouldn't work simply because of the nature of HDV i.e. it wasn't Vegas fault. I'm far from convinced we weren't being fed a line to coverup Vegas's shortcomings. Having pushed that line myself I witnessed a test of this theory. We used two HDV VCRs and an old Sony RM-450 edit controller using 422 deck control. Much to my surprise we were able to perform frame accurate assemble edits!
All I can say after getting egg on my face is it's remarkable the functionality of obsolete hardware compared to cutting edge software like Vegas.

If you are working with HDV You might as well shoot in HD and than transfer in HD into Vegas. Playback performance of such material is very good in Vegas 8. Picture quality is also improved in the final render as you have one less reduction.

If you find the performance is not acceptable, then I would advise that you still transfer in HD, but render each clip to SD for editing in Vegas. Then if you wish to return the HD version to the project, you just need to go back to the archive and swap them in to the "project media" window using the "replace" function.

If you try and sync back in with a new transfer from the original tapes I think you are going to run into problems. I do not think that transfers are handled the same way by the DV and HDV transfer programs, and you will mostly likely find that the start and end frames are in different places, meaning you edit will go out of sync and be messed up, requiring lots of fiddling and reference to the old version to fix.

thanks,

my main problem is (and i've griped about it often enough in this forum) i edit remotely for clients. they simply send me a rough cut edl, i do the rest.

not being able to batch capture in hdv (expletives galore), i was hoping that my client do the dump to sp via camera (hopefully retaining tc, or as close too as poss), i then edit as usual, then if need be, grab the hdv tapes and point the veggie to them 9assuming same name protocol, etc.,)

hi bob, sdi is way too an expensive step, but which 422 decks did you use? i still have a 450 lying around here someplace!

thanks

SDI?

Never mentioned SDI! Some of the HDV decks (M25) have 422 deck control and will transfer HDV over firewire.
I can't see why the 422 control port should work any different to how the deck control over firewire works i.e. we should be able to get frame accurate ingest from an EDL over firewire.

sorry bob, i think we once talked about having no problems with tc in hdv over sdi?

meanwhile, now that you've tested it, WHAT'S UP!!?? if you can rock'n'roll accurately with a 450, why can't you batch capture hdv?

scs, any explanation, please?
