I'm wondering if it's really recording SD to the HDV timeline
I filmed all weekend and got about 10 tapes, I had 40-50 shots of smooth slow motion that are moments you can't really get again and when we watched it on the TV it looked great (well it was SD!) but once I import it to my computer it looks horrible, if I scale the window down to about SD size it looks pretty good...
I'm just curious if it's recording at a lower resolution for that...
I'll post up some examples if people care...
I have an FX7 btw

there is a feature on V1 that does slow motion but at half or quarter resolution (depends how long you record).
probably it is the same on FX7 ?

Ah, it's locked at 6 seconds (I know the V1 does 3sec, 6, and 12... If I could do 3 sec burst and still have full resolution (even 720) I'd be happy...)
Sucks that I didn't find out about this later, I would have rather just stuck in normal HDV :(

you still can do slomo at good res.
just use virtual dub to split your 60/sec interlaced frames to 60 progressive pic/sec. it will gives you 2x slomo at halh vertical res. (1440x540).
then you can interpolate between each picture with some software (motion perfect ?) and go slower (4x).
look here http://www.100fps.com/
or perhas it is clearer here http://dvinfo.net/conf/showthread.php?t=50375

There's a real good article on doing this in this months DV magazine. Not sure if it's posted on-line yet. The author claims it's like what you get from a Varicam! I haven't tried it yet.

It's definitely half/quarter resolution (I'm thinking quarter)
I was thinking maybe it was in SD mode for slow mo recording...
I guess it makes sense, buffering 120fps for 6 seconds at 1440 x 1080 is a lot of work :P
I know how to de-interlace, if I could convert my 60i stuff to 60p I'd be happy.

Hey check out the slow mo feature on the V1. I shot this at a 4th of July event.

I captured this video in Premiere with HDV preset. When you click on properties it says the video is 1440x1080. I projected it onto a 10 foot screen and it looked great.

It's a 480 x 270 clip enlarged to 1440 x 1080... I think... stored on the HDV timeline
I'm not positive, but I know when I scale the window down, it looks more accurate than at full 1920x1080 (1.33 pixel ratio)

465 x 260 is what I ended up with I think... probably the wrong resolution but it looks decent
8 minutes of slow motion :P
That's roughly the resolution you get with the FX7...
