Time
‘Follow the money’
journalism 101 reminds us that:
‘Content is King’
And Mr. Benjamin Franklin remarked that:
‘Time is Money’
then…would it not be prudent to assume:
that in order to gain financial growth, we should carefully,
expeditiously and with format integrity remaining a top priority, watch and
follow the flow of content (media assets; be that video, audio, files,
scripts, stories and even databases) throughout the ENTIRE production
process, and doing so, use the ‘less is more’ approach with available
technology?

Broadcast File Format
by Katie Mims on Oct 2, 2008 at 3:09:11 am
Hi all,
I'm venturing into my first experience with broadcast video. Previously, everything I've done has been for the web, DVD or large
screen projection.
“The last person I spoke with at the
station said an MPEG2 was a good file
to go with…”
I just spent two weeks in the Caribbean islands doing hurricane relief work, and several of the local stations want to air a short
video I've put together. I wanted to get some feedback on my workflow, and find out if there is a better way to be going about
this in order to get the best quality possible.
Shot on: HDV 1080p24, Sony HVR-V1U
Captured as HDV
Edited on a 1080i60 timeline
The last person I spoke with at the station said an MPEG2 was a good file to go with, but I did a test run of it and the quality
didn't excite me at all. There were image issues, especially on fast pans etc.
" If they want a file, try to send them the
native file format that you're editing…”
My friend also gave me these guidelines: " If they want a file, try to send them the native file format that you're editing. Make
sure your whites are under 100%, 30 seconds of tone, 5 seconds of slate, 8 second countdown (from 10 to 2, leave the last two
full seconds black)
Tone should be at -20 and do not let your program go over -6, average should be around -10, speaking should never fall under 18 - keep it closer to -10 -12. You might need a compressor for the voice, we usually do."
So, advice on what I can do to preserve the picture quality, and can anyone tell me if there's a better file.
Thanks in advance!
Peace and Love,
Katie

Codec (in)Dependance
• One cannot stress enough how important the CODEC is
in the workflow
•It’s extremely easy (and quick) to
translate metadata (think of your
contacts file when porting from one
application (Microsoft Outlook) to another
(Blackberry/iPhone) contacts
•Containers (Wrappers) are
easily exchangeable (watch out for
possible metadata loss!)
•It’s when a CODEC change
(Transcode) needs to take place that
errors are typically introduced
Harris Proprietary Information
assuredcommunications™
Common Pitfalls
•
QuickTime *.MOV extension (QuickTime is not QuickTime)
• NB! *It’s just a wrapper* but where is it’s header?
•
•
•
Where did it come from is usually a good clue of format.
• Look/ask for what the essence is inside
•
•
•
•
•
XDCamHD 35 (4.2.0) or 50 (4.2.2)?
DVCProHD 50 or DVCproHD100
AVI, IMX30/40/50?
ProRes
Watch out for QuickTime Reference files.
•
•
In the header section up front
In the body section? Some servers fail when it’s buried too deep
down in the file -due to incomplete file parsing routines/techniques
Disk-efficient file points to various bits of the captured video, which
doesn't render until you use the QTRM to produce another file via
Compressor.
Where is it going to? (final destination)
•
Playback Server is going to be somewhat restricted on final file format
(codec)
Harris Proprietary Information
assuredcommunications™
Common Pitfalls
•
Media eXchange Format *.MXF extension
• All too often it’s assumed that MXF is MXF…
• MXF is only the wrapper and there is many different vendor
specific variances, interpretations and implementations of this
wrapper (Harris=*.LXF, GVG=*.GXF) Due to undefined MXF definition
• NEVER assume that if your video server (or NLE) shows in it’s
GUI that it can import (or even export) MXF, that it will work the
first time. Watch out for Versionitis!
• Check for the origination device and it’s export codec used
• I.e. FCP export via Apple Compressor and using ProRes.
• Where is it going to (final destination)
• Common server file types accepted:
• SD-AVI, IMX, DV, DVCPro, Mpeg-2
• HD-XDCamEX, XDCamHD35/50, DVCProHD 50/100,
Mpeg-2 w/various GOP’s, H.264/AVC-Intra
• **Watch out for metadata mapping when exchanging
between devices (especially in transcode processes)**
Harris Proprietary Information
assuredcommunications™
Common Pitfalls
•
Transcoders (Hardware)
• Quick, Easy but expensive alternative to ‘getting it right the
first time’
• Telestream’s FlipFactory – great but you pay for each
decode type. Don’t pay for unnecessary transcode ‘codecs’
• Rhozet’s Carbon Coder, ProStream - competetive
• 1 million other software only engines out there vying for your
attention, time and money.
•
Transcoders (Software)
• CPU intensive (need for speed factor), Easy and inexpensive
alternative to hardware solutions.
• MainConcept is the ‘Swiss Army Knife’ of NLE codecs with an
anything in-anything out repertoire.
• Marquis Broadcast’s Medway exploits the Avid file I/O
accessibility issues with the closed DNx/DNxHD codec AND
has great workflow media management tools too! (but not always
necessary)
Harris Proprietary Information
assuredcommunications™
Format (in)dependence
• Look for manufacturers who can and are willing to assist in
alleviating the devices, mechanisms and enhance (shorten and
tighten) the workflows in-between origination and on-air devices.
• Be overly cautious of the device that professes to ‘do-it-all’-Make
them prove it first.
– Do they offer a wide range of codec export support?
• (more arrows in your export quiver to better integrate with a minimal
CODEC supported playback server) Automate/Batch export?
– Does the playback device offer a wide range of import codec file
type support or is it fairly proprietary? (Supports only a few file
types only.)
• Again, don’t assume MXF is the killer “FIX” to cover your situation.
Ensure the header and container is compatible with the downstream
device’s import capabilities.
Harris Proprietary Information
assuredcommunications™
It is a riddle wrapped in mystery inside an
enigma; but perhaps there is a key –
’UNOBTANIUM’
• Resolve yourself to the fact that:
– There is no single file type that is going to suit all your needs.
– Acquisition (Camera)
• News = XDCamEX18/35. XDcamHD35/50. DVCProHD50/100
• Studio = DVCproHD100. AVC-Intra
– Editing (Production)
• News = XDCamEX18/35. XDCamHD35/50. DVCProHD50/100
• Studio =Apple Pro Res. Avid DNxHD. DVCProHD. XDCamHD50
• Promo =Apple Pro Res. Avid DNxHD.
– Playback (Air)
• News/Promo = XDCamEX18/35. XDcamHD35/50. DVCProHD50/100
• Spot/Commercial = MPEG-2. MPEG-4 AVC/H.264.
– Storage (Archive)
• MPEG-2 Low bitrate + Long GOP, MPEG-4
FYI* AVC-Intra and DVCProHD use I-Only compression, while HDV uses Long GOP compression. The MPEG-4 AVC/H.264 standard
encompasses both methods.

– Import your files in Final Cut Pro or AVID Media Composer by
• Creating XDCAM HD422 files in .mov or .mxf
• Creating XDCAM IMX/D-10 files in .mov or .mxf
• Creating AVID DNxHD files in .mov
– Transcode your MPEG-2 4:2:2 Transport stream files containing S302M
audio.
– Transcode your AVCHD Camera files correctly.
– Merge and split your audio tracks.
– Create QuickTime files containing time code tracks.

So……
• Know your particular device/s file type capabilities
– NLE’s can generally handle almost any file type in or out but this is where
the confusion starts (too many options across too many file types)
– Servers are less capable on file i/o. If attempting import/export for the first
time, get a sample file to the manufacturer for testing. If you don’t have the
analysis tools, they certainly will (should!) be able to help you debug the
file’s headers, containers, wrappers and essence.
– DG FastChannel/Pathfire, Pitchblue file content need transcoding as most
servers cannot directly import these files due to either/or the MPEG-4
AVC/H.264 files at a data rate of 15 Mbps or more AND the handling of the
metadata for the CBS automation and trafficking needs required parsing for
this file type. Expect future device maturity.
– If it has scripting/macro capabilities…….make/take time to exploit them.

Quote of the day. Anyone? Anyone?
In 1930, the Republican-controlled House of Representatives, in an effort
to alleviate the effects of the... Anyone? Anyone?... the Great Depression,
passed the... Anyone? Anyone? The tariff bill? The Hawley-Smoot Tariff
Act? Which, anyone? Raised or lowered?... raised tariffs, in an effort to
collect more revenue for the federal government. Did it work? Anyone?
Anyone know the effects? It did not work, and the United States sank
deeper into the Great Depression. Today we have a similar debate over
this. Anyone know what this is? Class? Anyone? Anyone? Anyone seen
this before? The Laffer Curve. Anyone know what this says? It says that
at this point on the revenue curve, you will get exactly the same amount
of revenue as at this point. This is very controversial. Does anyone know
what Vice President Bush called this in 1980? Anyone? Something-d-o-o
economics. "Voodoo" economics.
