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] Shooting with Sony A7 to XAVC S compared to AVCHD or MP4 Quality?

 

I used to abhor working with DSLR footage but now, INHO Sony's A7 and now the A9 have really improved the experience.


Even the point and shoots are great. I bought an RX100mark V and it will do limited recording of raw stills at 24 fps and record 2k internally (not that I have a burning need for 4K) and it fit's in my pants pocket.  I wanted a good still camera DSLR. I original was looking ad Canon 5D but then read the reviews on the A7s.  so I bought an A7II and am really pleased with it.  That said, Sony needs help designing user friendly software settings.

Re: [Avid-L2] Shooting with Sony A7 to XAVC S compared to AVCHD or MP4 Quality?

 

Thanks for the insight.  I had just looked at the Camera page specifications.  The footage I'm getting is XAVC S but it's 8 bit 4:2:0.  I wonder if they could up it to 10 bit and 4:2:2?  Sounds like that may be a possibility.  What I don't know is if they could choose to shoot in XAVC instead.  I think then the material would ama to Avid.  I only see XAVC S listed on the camera Image size so perhaps that's all the camera is capable of.

A quick look at Sony's primer says this:

What are the differences between XAVC and AVCHD?

XAVC format provides 4K/HD, 4:4:4/4:2:2/4:2:0 and 12/10/8 bit sampling which can cover a wide range of applications from professional to consumer products, from high-end 4K production through to online streaming and consumer imaging applications. AVCHD, by contrast, is capped at 24Mbps for 1080 50i/50i or 28Mbps for 1080 50P/60P at 4:2:0 8bit sampling and is fully compatible with the Blu-ray disc format. Both XAVC and AVCHD formats adopt the same MPEG-4 AVC/H.264 compression technology, but there is no compatibility between them.

What is XAVC S?

XAVC S is a subset format, using many of the superlative techniques and technologies used in XAVC, but intended for consumer products and workflows. It supports the 3840x2160 pixel version of 4K only, known as Quad Full HD, QFHD, UltraHDTV or UHDTV. XAVC S is a lighter codec with Long GOP compression and relatively small recorded file sizes. XAVC S also uses the .MP4 file wrapper for greater compatibility and suitability in consumer workflows.

So yes, I would agree that XAVC-S has the potential to be far better than AVCHD.

and
MP4: 1920 x 1080 (60p/28 Mbps, 30p/16 Mbps)


I've read on the L2 that data rate isn't always a clear indicator of image quality as the type of compression and it's efficiency play a part so a lower data rate can be deceptive.

Can any of our more production savvy folks confirm of deny or explain if shooting XAVC S on the Sony a7RII is better quality than shooting AVCHD or MP4?  Our camera person is convinced that shooting XAVC S yields better quality even if it means we have to transcode to make it work in Avid.  Any insight would be appreciated.

Re: [Avid-L2] Premiere subtitle demo video

 


That has been fixed :-)

It now gives the option to see either my subs, or the auto generated ones.

You know you can customize the look?
