SD 4:3 Firwire Out

[Ron Edwards]

I shot some video in Quick Time File Format, 1280 x 720 Resolution, 50p(HQ) and now I am trying to play the video and firewire into my editor as an SD DV signal. I was able to do this one time with interlaced video but now I can not see any signal at all with this setup. It was my understanding the firewire output and DV selected resulted in the camera downconverting a SD - DV at 60i ?

Any ideas?
Thanks !

Yes. Set the Firewire switch to EXT and DV.
The HM700 downconverts to DV NTSC 60i for source frame rates of 24, 30 & 60. Since you shot 50p it will downconvert to DV PAL 50i so you will need to set that as your capture preset before opening log & capture. I'm not sure if the camera will create 50i (using all 50p frames and interlacing them) or 25p (dropping every other frame from 50p) on downconvert.

If you want the camera to output 4x3 (cutting of the left and right edges) then go into A/V Out menu and set DownConvert to Side Cut.

Tim,

Thanks for your reply.

My editor (Macro Systems Casablanca Solitaire) will only accept 16:9 or 4:3 material in SD. It will accept progressive or interlaced but not 50p.

So I need some help converting the 50p to 60i. Any ideas?

So it's a NTSC only system?

Did you shoot in MP4 or MOV format?

[Ron Edwards]

Tim,

That is correct NTSC only. The shoot was:

Quicktime
1280 x 720
50p

For some reason, I thought the cam downconverted anything it shot to 60i (NTSC) when set for DV output.

Can your system import composite NTSC? If so I think your basic solution is a composite PAL to NTSC converter box. It won't be pretty but it will get the job done.
