Timeline Profiles EDIUS 6

[Red Union Films]

Just checked my Tektronix HD format chart and they listed a 4:3 HD (720 x 576 pixels) format as 625/50/1:1 Progressive with 625 total lines per frame.

I will check to see if this appears from the output of my Edius Thunder (almost Storm 3G) card.

Hi Jim.

I think you may find that Tektronix format is bespoke and not a standard. If memory serves me well, HD for film and tv was only ever deigned to work at a screen aspect of 16:9. When you have a 4:3 picture in the HD world, it is just placed in the middle of a 16:9 background. This will have a lot of wasted pixels either side, weather at 720 or 1080. Although this center 4:3 image on a 720 background looks to be 960x720, this should not be mistaken for the anamorphic variation of 720. I could be wrong, but all HD is 1:1 pixel aspect and 16:9 screen aspect, and 720x576 with 1:1 pixel aspect is neither a HD format or a legal PAL standard.

Hi Steve.

On the list is 23.98 actually that, or is it realy 23.976 ?

Cheers,

Dave.

It is 23.976.

Before there is any confusion the list has to do with out of the installed GV hardware not with export.


Thus what you can send out to a connected panel (realtime) and NOT what you can export (file based).

Just anothert query about SD/HD PAL. From memory there is a preset for 720 50P (4:3) which doesn't appear on the list.

I have used this for outputting a stream of stills of each indivisual field from standard PAL video by converting a project from 50i to 50P (and it worked really well).

Interestingly I have heard it said that anything above 720 50/60i is regarded as HD so perhaps this information belongs on the HD part of the document. Even more confusing!

Hi Jim.

720 is a HD format and does not come in 4:3 format, this would be why it is not the list as 720 50P 4:3. For PAL, it's only 576 that has a legal aspect of 4:3.

While I do know the answers to these questions I will check with engineering before I post the official answer. :)
It might take a few days.

Thanks GV for that very useful document. I often promote the use of Edius with my colleagues who need an NLE for their research work. I have to explain that Edius needs to be told what format they need when they begin a project and this leads to a discussion of HD formats out there. They do find it confusing so any material like this is a great help.

Hi Steve thanks for the link... but can you tell us why there is no option for monitoring native 1280x720/23.98p or 23.976p as Dave correctly points out.
The only project option is for OHCI and this cannot be monitored via the GV hardware cards....it is a common enough format so what is the reasoning behind this lack of support?

Best

Dave.

There is new document available which give a comparison between
the HDSPARK,HDSPARK PRO, HDSTORM, STORM3G/3G ELITE.

This gives a a good overview what each board is capable of outputting and what cannot. (thus will use software preview)
