Re: [Avid-L2] Re: DNxIO Artist output HD and SD SDI at the same time?

 

Wow that's great news.  I had experimented but found I only could get HD signals if I was in Quad Link mode.  I didn't dig into the manual far enough I suppose.  I think that working in 4096x2160 also throws a potential glitch as sometimes my monitor will lock to the 2K signal in the Quad Link mode and sometimes not.  The work around was to set it to 3840x2160 and deal with the letter box.

So if I'm understanding even when I set the Avid internal video output settings to 3840x2160 hardware if the BM control panel is set to single or dual link then the 3rd and 4th bncs in the output quad will have HD signal.  I didn't see anything in the control panel that indicated that functionality when I switched modes so I figured it wasn't there. 

So with this new awareness I can feed HDMI 4K to my big 4K screen and send the 3 or 4 output to my normal  SDI scope and ref monitor all at the same time.  I'd just been feeding the HD out the HDMI and switching to 4K for final viewing for pixel issues.  In practice though I could swear I see more sharp edges when I run HD into the 4K monitor than when I switch to 4K UHD output.   It's very slight but on certain face shots it seems like the HD signal gets more enhanced/sharpness.  Perhaps this is due to the upscalling by the monitor but I thought if I was close enough I would see more detail in 4K mode.  Maybe my eyes are playing tricks on me.

Background

Avid-L was established in 1994 at Calvin College by Steven Koster.
It was created to be a forum for Avid users to meet, discuss, and share
information.

Avid-L quickly grew into the premiere on-line users group for
professional film and video editors. It was one of the earliest examples

of an Internet community, allowing hundreds of editors worldwide to
share their experiences and expertise with their peers. There was no
better place for a professional Avid editor to get such wealth of
informed professional advice.

At various times, individual subscribers volunteered services to the
group. Searchable archives were maintained by Germany's Berlin Users
Group as well as the UIUC. A tips & tricks list was posted by Andy
Birkhead of Innovative Edit. Wes Plate, a longtime contributor, not only

shared key techniques on his Web site, he also created a photo gallery
for members' portraits.

In 1997, several subscribers began a tradition of meeting in person at
the NAB trade show in Las Vegas. The first gatherings were organized by Jaime Fowler. In 1999,
Avid Technology itself began sponsoring these gatherings as an exclusive reception and seminar for Avid-L members only. In 2002, this changed to the "Avid Users Group" meeting.

By 1999, Avid-L boasted over 1600 subscribers, exhibiting a true
international scope with over 300 international members. The community
included participants from a wide variety of well-known corporate
organizations in broadcasting, technical, and content creation fields,
as well as and multiple local TV stations, colleges, and universities.

In 2000, Avid-L joined AvidProNet.com, and then, in 2002, was integrated
Into Avid.com.

In 2005 Due to problems with signal to noise ratio and abusive posters, the Avid-L2 was formed. A year later the Avid-L was discontinued by Avid.

At the middle of 2006, the L2 has around 1100 members, with plenty of "lurker only" members who simply use the web version of the list. The L2 is spam-free, by moderation and with Yahoo's tools and will remain that way. The integrated archives with both old L and L2 posts came on line recently as well at the University of Illinois. That can be found at http://archives.itg.uiuc.edu/avid/.

Cross-posting to the FCP-L is welcome, tho reply's will not flow back to either list necessarily- check your own email reply preferences. The Final Cut list is found at: http://movies.groups.yahoo.com/group/FinalCutPro-L

Welcome, and Enjoy!

Re: [Avid-L2] Introduction to 4K Document

 

Paul, This is an excellent article. Thank you for writing it. I would
suggest adding a short section on data compression. It's the elephant
in the room and what makes this possible/practical. I would also insert
the word compression between each of the bullet points in the section on
Colour Management.

BTW, here's an interesting (and not for publication) tidbit on data
compression as it relates to higher pixel counts and higher bit depth.
I had coffee a few weeks ago with Khalid Sayood (Introduction to Data
Compression, etc.). I asked him if he thought we are approaching a
leveling off of the ability for new codecs to deliver both higher
compression rates AND higher perceived quality. His answer was no.

Again, thanks for the article. --J.B.

[Avid-L2] Re: FW: DPX debayer issue in Media Composer 8.6 and up

 

I'm not sure if this is related or not, but there is a major bug that's been in at least the last two versions of media composer. You can get errant chroma shifts, and digital hits, and incorrect fields from other areas. It's all related to the GPU. Try turning off "use GPU for rendering" and see if that makes a difference.

[Avid-L2] DNxIO Artist output HD and SD SDI at the same time?

 

Does anyone know if it's possible to output SDI in both HD and SD formats at the same time from a DNxIO box? I know I use to do it on the Nitris DX, but that had separate jacks for HD SDI and SD SDI. On the DNxIO box it seems like all the SDI ports are multipurpose and I'm not seeing a way in the Desktop Video Setup software to assign some of the SDI ports to be HD and others to be SD at the same time.

Thanks,

Re: [Avid-L2] DPX debayer issue in Media Composer 8.6 and up

 

They do allow 16 bit DPX as an export option.  I have only used 10 bit based on my source material but I wonder if there is an issue with a 16 bit export from 10 bit material.


---In Avid-L2@yahoogroups.com, <jay_mahavier@...> wrote :

AFAIK, and all of my experience, currently, and for as long as I know, Media Composer only supports 10bit DPX.  It's not a bug, so much as it just doesn't support 16bit DPX.  I would be nice if they added support, but don't hold your breath.

Hello all,
Wanted to flag an issue we've encountered recently, just so the people on this list can spread the word and don't also fall foul!
Our issue was using MC version 8.6.4 on both PC and Mac where by when 'linked' to any DPX media higher than 10bit (12 and 16 we have tried), there is a visible red & blue shift in picture as if whatever is debayering the picture is not assembling all the channels (RGB) correctly. Consequently you get a one pixel blue highlight on right of things in image, and a one pixel red on the left. We have since tried with the same result in 8.8 so the bug is still present currently.
This is from DPX media generated in resolve, nucoda and baselight, so seems to be everything we encounter on a day to day basis!
 
According to our Avid UK contact this is a known issue on their part, but I don't believe it is published anywhere as a known issue so look out for it!
 
Thanks,
Adam
