Can FMV use the position information (metadata) that the Garmin Virb Elite records?

Hi Steve,

The Garmin Virb Ultra has a standard app that is delivered with the camera that converts the required metadata into a csv that is input directly into the FMV Multiplexer tool to create a FMV-compliant video file. Please refer to the Garmin user's manual or your dealer for information on how to use the Garmin app.

Best,

Jeff

You might consider MediaGeotagger from RedHenSystems.com... We have sorted out a number of "Clapboard" methods for geotagging video and imagery - works for really any camera and track logs you might have.   To properly express the VIRB content, a transcoding process to MISB normal KLV  form is required.  This is also a process that requires a decision if the SPOI is the frame centroid or frame perimeter to establish how the ArcGIS FMV engine operates.  If the camera orientation is noisy and/or mis-calibrated, aka uncertainty of the actual IMU, in our experience the frame centroid is a better off-set. Why?

BE-AWARE - azimuth is easily drawn-off an accurate magnetic north by adjacent vehicle iron and steel mass, including slightly magnetized helmet rivets, GPS antenna magnets, batteries, and others.  The IMU is good at tilt (gravity does not vary greatly) and GPS is measured in RMS and CEP.  Figure a worse-case 30 degree error for out-of-your-pocket handset and actioncam IMU orientation/calibration to magnetic North.  This is a rule-of-thumb figure four percent error, eight percent full swing, or 30 degrees for handheld camera.  For stabilized gimbals with 12 bit positioning on three or more axes, well figure once percent improvement for each additional $100k.

The record system that Garmin VIRBS provide  are essentially a proprietary form of NMEA schema with some proprietary extensions for their related sports and training sensors. MediaGeotagger normalizes the VIRB trackings to NMEA standard which then operates as the geotagging side-car to drive the generation of the required SPOI values for insertion into the synchronized  KLV transport stream. This step is a bit critical and magical.  Given the tradition of SPOI is deeply related to the military concepts of cursor-on-target and that responsibility, we rely on ParGovernment's "GV Video Framework (Gv2F)" transcoder for the final transcoding to the FMV form. This is the same essential transcoder that is found in the Esri offering known as FMV.  The Red Hen module XML2KLV is a special-case we have directly cooperated with Par Government through their Gv2F toolkit that offers an optimized C media framework for C++ and Java bindings.

Neil - Please refrain from steering our users away from Esri's integrated partner solutions to advance your personal business agenda.  This is unprofessional behavior.

We have a long history with ArcGIS over the years.  MediaGeotagger has a long history geotagging media and photography and you may recall it as PixPoint or GeoVideo in the Esri ArcMAP era communities.  IsWhere is the evolution of those very early geotagging and FMV products on ArcGIS 9.xx and earlier.  Actually an Esri Red Hen feature I wanted to share but decided to test a bit further is our IsWhere app. 

Interestingly, an update of ArcGIS Earth grabbed the KMZ extension on a recent project I want to load on IsWhere.  I was surprised that with a bit of jiggering around the current ArcGIS Earth release it looks like it has legs for FMV on ArcGIS Earth?  We still are testing new stuff in the general ArcGIS Pro as received in the last weeks versus streaming services and VLC or Micorsoft Viewers.  This is including looks like a most of the conforming 360 cameras via equirectangular MP4 formats with Facebook header metadata.  And pushing a bit more and building a complex collect Arc Earth is in the works this and next week but you too are welcome to give it a go?  On the moment, we are learning about how to populate ArcGis Earth with Pro layers and leveage the Earth interface with our simplified FMV IsWhere viewing solution.  We are also trying how Server might contribute to Earth as well if that makes sense?  We are excited in all of these enabling innovations and like what we have heard on next steps for 3D Earth that Pro offers as well.

Anyway the good news is the style of media we fuse metadata into includes SPOI generated from several tools on PLAY and NGA GeoINT Apps Store - these tools generate Street View like content aka Mapillary for local use and or via the GeoVideoLIVE add-on of ArcGIS Server.  The translator that creates MISB specified FMV uses the Par Government's FMV and other ISR tools that contributed features to the ArcGIS FMV.  Par Government has been a long term source of excellence in the domain of FMV / ISR and these products are also in the Esri developer community.  We endorse them as do others.  As we regard Garmin, well "Garmin has been very, very good" for Red Hen over the decades.  We have used VIRB and include  them in the stack of cameras we support for their extended geospatial qualities for a very long time - we anticipate seeing more of this style of video listed on YouTube. We have presented near real time DJI via YouTubeLIVE as well.  We think that is pretty neat and if IsWhere remains stable on ArcGIS Earth,we successfully populate layers from Pro and Server well that too is interesting. 

We are about better camera usage for GIS purposes as THISR aka tactical handheld ISR.  We like the ArcGIS Earth opportunity for the same.

Stay calm - we have some skill partner skills and products we want to share.  Its on me to make sure we are clear.

The Oh, they places you will go! that IsWhere and GeoVideoLIVE may offer for ArcGIS Pro and Earth is good news. And watch for a really neat FMV 3D/360 offering toward late Fall is our guess.  Wanted to share some insights we have on FMV - didn't mean to stomp about.

Has anyone tried it with the Garmin VIRB 360?

Virb 360 has a proprietary metadata that requires normalization to the ArcGIS form of FMV.  MediaGeotagger can conform the Garmin Metadata to provide XML structures - available at NGA GeoINT Apps Store. As a 360 image with equirectangular frame it will not conform to MISB SPOI.  The Garmin is quite over priced as a spherical camera with quirky features in a two year old design that is out of alignment to easy use IOHO.  The Theta and several other <$400 provide superior images and are "StreetView Ready".
