In order to create the video frame footprint (frame outline), one needs to include elevation values for the ground surface (or height of drone above ground). In ArcMap one only has the option of specifying the flight altitude while for Pro one can also use an imagery service. I have tried both methods and I still have the same problem. I hope someone can advise me how to fix it?
Autopano Video Pro 2.3.0
The problem I have is that my video frame footprints are not being accurately located in GIS. In fact they almost never overlap with the actual footprint. The calculated video footprint is always displaying a much larger area to the front of the drone.
I tried looking at this in a scene view and the multiplexed video correctly shows a 'leader-line' or video image center line that is centered in the actual video footprint (not the calculated one). See below image.
The Cirruas app records the below metadata which should be adequate in calculating video image footprints. I include the minimum and maximum values recorded for the above flight in case anything stands out. For example, should Platform Heading Angle and Sensor Relative Azimuth Angle not be in the range of 0-360?
Mervyn, I'm curious if you could tell us more, or share your video. I've used ArcMap to multiplex your CSV file using a random video on this end, and the footprint looks fine to me, but you're indicating it is not in the right location. That should be improved in Pro 2.3 (available soon) to consider the terrain, but it sounds like you have some relatively consistent errors (footprint "always too large to the front of the drone") - have you tried adjusting the FOV values and/or sensor elevation (pitch) angle?
I can confirm that I am now using ArcGIS pro 2.3.0-beta 1 and I can now get the video frame to more-or-less match that of the video frame :-). But not always, it depends on device used to capture log file.
I have the Cirruas app loaded on two devices; a tablet and a phone. If I (1) record a log file using the phone, then, where it used to get the display error reported above, this is now fixed in Pro 2.3 (awesome). However if I (2) record the log file with my tablet, then I always get the below error in Pro only if I insert an elevation surface to calculate the frame extent. If I remove any elevation surface in the tool, then the tool will multiplex the video although it will have no frame.
If I try and run the video multiplexer in ArcMap, and set the tool to Calculate Corner Coordinates using an average ground height, then it is able to do so using teh log file where Pro failed. I have also upgraded my version of ArcMap and FMV extension so no more strange video frame errors being created from what I can tell.
Streamlink is a command-line utility which pipes video streamsfrom various services into a video player, such as VLC.The main purpose of Streamlink is to avoid resource-heavy and unoptimized websites,while still allowing the user to enjoy various streamed content.There is also an API available for developers who want accessto the stream data.
Because the upscaling in NVIDIA Image Scaling is performed by the GPU, and not within the game, software-based video capture methods will not record the upscaled gameplay at the target (native) resolution, but instead at the lower pre-upscaled resolution.
Screenshot and video capture of NVIDIA Image Scaling will therefore require special driver-level support; screenshots captured through GeForce Experience using Alt+F1 are supported now, and video capture support is coming soon. In the meantime, gamers can use a dedicated capture card such as Elgato 4K60 PRO MK.2 and Avermedia Live Gamer 4K.
Whichever GeForce RTX GPU you own, NVIDIA DLSS enables you to speed past 60 FPS at 4K, with every in-game option cranked to the max, for the definitive Hot Wheels Unleashed experience. See for yourself in our new NVIDIA DLSS ON-OFF video:

This license is commonly used for video games and it allows users to download and play the game for free. Basically, a product is offered Free to Play (Freemium) and the user can decide if he wants to pay the money (Premium) for additional features, services, virtual or physical goods that expand the functionality of the game. In some cases, ads may be show to the users.
This option will perform smart transcoding consisting of checking the Master video codec and audio format and deciding whether to transcode or pass-thru the stream. If the Master video codec is already an intermediate or mezzanine codec such as ProRes, DNx or CineForm, a pass-thru will be performed instead of re-transcoding. If the source audio codec is PCM (16 bit / 24 bit / 32 bit), then the Master audio stream will be pass-thru. If it is not PCM, a transcoding will be performed at the set value (16 bit / 24 bit / 32 bit).
Audio and video streams are treated independently and they can be transcoded to the desired format or passthrough. Audio streams are mapped 1:1, meaning that the transcoded files will have the same number of audio channels as the master ones.
The Passthru transcoding option enables 100% quality pass-through of Master audio and video streams, embedding metadata in native format and in XMP format (supported by Adobe Premiere Pro). In this mode the output container is set to quicktime except for MP4 input files which is maintained as MP4 for codec compatibility.
Available audio formats are: 4K (4096x2048), 5.6K (5376x2688). This option is designed to select the preferred Equirectangular resolution of the exported 360 video if any raw GoPro .360 video is processed.
everExpanse can also process the GoPro 360 proprietary file format which uses a 360-degree video projection type (Equi-Angular Cubemap projection or EAC) not directly compatible with the type of projection (Equirectangular) supported by streaming platforms or video editing applications. evrExpanse is able to converts these raw .360 files to equirectangular projection video and transcodes them to intermediate codecs embedding the master file EXIF metadata for uploading to YouTube or 360 editors, such as DaVinci Resolve, Adobe Premiere Pro, or Final Cut Pro.
