Playback of HD250 content on HD100 at DVinfo.net

Ben Lynn · March 30th, 2007, 10:08 AM

This summer I have a production that will use two different units. One will be a 250 and one will be my own 100. I intend to shoot both cameras in 720 30p. My 100 will be used for the playback deck so I want to confirm that content shot on the 250 will play back on the 100. I know that this "should" work, but if anyone could confirm this then that would help in the planning process. If the material isn't playable I'll need to rent a 100/110 instead of the 250. Thanks for the help.

As long as you shoot 720/30 or 720/24 I think you're okay. I don't think 250's 720/60p will play back on a 100/110 but I could be mistaken. I believe that the 250's 720/60p uses a 12 frame GOP while the 250's 720/30 & 24 uses the same 6 frame GOP as the 100/110.

Hopefully someone really in the know will confirm.

All frame rates from the HD-250 will play back from the HD-100 (50 and 60p included). I know this fact from personal experience.

good times...

And someone really in the know has provided the answer. Cool. I stand corrected. That's really interesting to know. Thanks Stephen.

Do you mean for firewire capture? or does the picture actually show up on the LCD?

yes to both...

the sales rep in my area said the same thing, yes on both.

I wonder how the HD100 can do that, since it shouldn't be able to read the 12-frame GOP signal.

MPEG-2 can have varying GOP sizes as long as they stay within a range of "about" 3 to 18. ATSC uses 15, ProHD uses 6 or 12, HD2 uses 15. It's the Repeat Flags of 24p that can cause a problem on early HDV equipment. I think I remember playing 60p on an HD1.

Sony's new V1 camcorder will even play ProHD tapes via HDMI at 720p60 -- but not 24p tapes.
