![]() ![]() ![]() IMatch allows you to put into XMP whatever you see fit. QuoteIs there any (XMP) Tag were this can be stored, and iMatch makes use of it? Lens: were I remember what it was and in future I would assign the lens to XMP::exifEX\LensModel\LensModel\0, using exact same Names as Exiftool -> then they are shown under the same category like the fotos.Ĭan this be done like that, or is it a bad idea to store such information in video files? Persons: assign them via "Link Persons to file"Ĭamera: from time to time I filter on all video files (on the three tags above) and then assign the CameraModel also to XMP::xmpDM\cameraModel\CameraModel\0 Most Metadata (GPS, Location, Keywords): use them the same way like on Fotos The Lens of the Nikon is detected by iMatch (I think via the Composite:LensID tag reported by exiftool).įor the other files I would add them manually to XMP tag: XMP::exifEX\LensModel\LensModel\0 ![]() ![]() None of the files (with exception of one file form a friends Nikon Z6 II: Nikon::NCTG\17867828\LensModel\0) have the lens information stored. Now I made a special Layout for videos, that will use XMP::xmpDM\cameraModel\CameraModel\0 as Camera info. So far I only found XMP::xmpDM\cameraModel\CameraModel\0, which also works, but iMatch does not display this as Camera Model (seems to use globally Exif::Main\272\Model\0). Is there any (XMP) Tag were this can be stored, and iMatch makes use of it? Persons -> OK, done via "Link Persons to file", saved in XMP (As side note: Face Detection is also running on the video thubmnail)Īll videofiles I checked have the Camera Model information in different Makernote tags: Location Information -> OK, saved in XMP data In general XMP tags seem to work fine: can also be saved in. Skybox at least has a way to adjust this in-player.I'm currently checking in a Test-Catalog how I could work with Metadata of Video files (so far I don't have Videos in my iMatch DB). I've not seen a way to set the FOV in the file name. The SteamVR video player also has auto-detection. Skybox has this and IME it works well, at least for 180 content. they look at the video content and try to do the right thing. Player-specific naming also exists, see Skybox for example.ĭedicated VR video players can have auto-detection support for the projection and arrangement. I've seen "180_LR" used to denote a side-by-side 180 video, and it works on the Oculus Gallery app on the Oculus Go (I don't have any non-discontinued Oculus devices, so I can't test if this is still the case). This post also mentions "_TB", "_BT", "_LR", and "_RL". Examples from this article:Īdd "_360" to the end for mono 360 videosĪdd "_360_TB" to the end for top-bottom stereoscopic 360 videosĪdd "_180" to the end for mono 180 videosĪdd "_180_3D" to the end for side-by-side stereoscopic 180 videos Some players (like the default players in Oculus devices) use file names to recognize the projection type and whether the video is mono/stereoscopic. I don't know what your exact use case is, but mine was immersive VR video (mostly in 180) and that's my context for this. When I last looked into it a year or two ago, all user-facing ways of injecting metadata seemed to be specific to uploading video to either Facebook or Youtube, both of whom handled it differently, and there was no universal standard way of doing anything. I understand I need to include specific properties like the FOV of the video, something I assume I can fetch from the settings of my camera in Blender and pipe into the appropriate video tags.Ĭan anyone list the metadata tags I need to set on panoramic and / or stereoscopic clips for video players to recognize them accordingly? Then how do I set them either in ffmpeg, from Blender if they can be baked into exr images at render time, VLC if it allows writing that information to a video, or at least a shell script for Linux which I'm familiar with and could easily use? I alternate between mp4 and ogv for video format if they're relevant.Ĭan anyone list the metadata tags I need to set on panoramic and / or stereoscopic clips for video players to recognize them accordingly?ĪFAIK there are none, at least none that are "standard" in the way I understand the term. It was suggested using special software to set this data, which is an extra dependency I'd like to avoid as I prefer using just Blender to produce the frames then ffmpeg to compile them. Only problem is I was told such videos must be encoded with special metadata baked into them, indicating it's a sphere mapped video and what sort. I recently read that VLC is among the first video players to properly support panoramic video, it's one I use so that's great news on the matter. I want to start making more 180* / 360* animations with Blender. ![]()
