Each platform has a different set of file formats which RV can read by default. In addition, it's possible to download or purchase additional file format plug-ins which allow RV to read even more. This chapter is an overview of the most important formats and how RV uses them.




Variable Geo movie download in mp4



Most movie file formats can have multiple tracks. When RV reads a movie file with two or more tracks it uses the first two tracks as the left and right eye when in stereo mode. You can create these files using the Apple QuickTime Player or RVIO on OS X and Windows or RVIO on Linux.


On Linux, RV will read the text track of a movie file if it exists and put the contents in an image attribute per frame. You can see this with the image info widget. Text tracks can be used to store metadata about the movie contents in a cross platform manner.


Our ffmpeg plugin does not respect all of the QuickTime atom objects. Usually this is a good thing as Apple's own library produces inconsistent results from platform to platform when displaying movie files with gama and colr atoms. The most notorious of the color atoms which typically affects the color of Photo-JPEG movies is the gama atom. The gama atom causes Apple's Quicktime to apply two gamma corrections to the image before it is displayed. RV will not do that and RVIO does not include the gama atom when writing Quicktime movies.


This is the latest and greatest codec which is usually associated with MPEG-4. H.264 stores keyframes and data which helps it generate in-between frames on the fly. Because it doesn't store every frame individually, H.264 compressed files can be much smaller than codecs like Photo-JPEG. The image quality for H.264 can be good depending on how the movie was created. If relatively simple creation software was used (like Apple's QuickTime player or RVIO) the results are usually OK, but not nearly as good as Photo or Motion-JPEG.


START and END are frame numbers in the movie. Note that START is the first frame to be include in the clip, and END is the last frame to be included (not, as in some edl formats, the frame after the last frame). For QuickTime .mov files or .avi files, the first frame of the file is frame 1.


Outputs the movie as a sequence of .exr images. HDR values are preserved but if the Tone Curve is enabled, linear values are scaled to approximately the [0-1] range with only the brightest highlights going above one. Disabling the Tone Curve writes linear values in the [0-100] range or more depending on the intensity of lights and other bright objects. No sRGB encoding curve is applied to .exr targets.


If you use the Command Line Encoder, you must accompany it with an image sequence export format too, in order for it to create movie frames from those images. If you want to include audio, you must also include a .wav Audio export.


Overrides the File Name Format from the Output setting for the movie that the Command Line Encoder outputs. You can use this to generate a single master movie file, instead of individual shot movie files if you are rendering your image sequences to separate shot folders.


Avid DNx [8bit] will now be available as an output setting. When you select this setting, it will output your movie as a video file using Avid's DNx codec. The video container will be .mxf.


The WAV Audio output format is experimental and may not be production ready. Because the movie renderer runs the engine between shots for warmup frames, audio that is not controlled by Sequencer will have gaps between shots. Additionally, there may be minor audio distortion on audio clips in Sequencer between shots.


The guide will take you through some of the settings you can use to produce a high-quality render outside of real-time concerns. You will learn to use the Movie Render Queue to configure a sample sequence using custom settings and console variables.


Scroll down to the Engine Feature Samples section, then select ArchViz Interior. When the CONTENT DETAIL window opens, click Free to download the project, then click Create Project. For this guide, leave the project name as ArchVizInterior.


An overlay with information such as the name of the scene or shot, or the date, time, or frame information. These overlays are referred to as Burn Ins as they are burned into the movie when it is rendered out. Can be replaced with a custom widget if needed.


You can call most of the console variables (CVARs) that you will want to execute when rendering from the Movie Render Queue. This is extremely useful for rendering high-quality results that are too expensive for real time.


If you want to know the details of a console variable, you can use the backtick ( ` ) key to open the console and search for that console command. Use the following format to display the tooltip:


Below are more console variables you can use in the Movie Render Queue to trade performance for quality. This is especially useful since this feature executes these commands only when a render is run from the queue, and the settings do not permanently override any of the real-time settings you might have set up in a post process volume in the editor.


DRM-free downloads offer content that is not limited by standard Digital Rights Management (DRM) access technologies. These technologies allow hardware manufacturers, publishers, copyright holders and individuals to limit the usage of digital content.


When you purchase DRM-free downloadable content, that content is available for you to download on any computer and save to a disk whenever you like. You can also download to multiple computers. There is no timeframe associated with your purchase and the content will not expire.


Unreal and Unity both provide their own marketplaces, although much of their content is catered for their respective game engines. ArcGIS does consume many popular formats though, and you should have no problem finding surfaced models that can be consumed across the platform. glTF or GLB is probably the easiest formats to consume that have both PBR surfaces and provide consistency within ArcGIS for rendering of models. Both these formats can be downloaded on Sketchfab.


Use this prefix for unqualified URLs. E.g. "gvsearch2:python" downloads two videos from google videos for the search term "python". Use the value "auto" to let yt-dlp guess ("auto_warning" to emit a warning when guessing). "error" just throws an error. The default value "fixup_error" repairs broken URLs, but emits an error if this is not possible instead of searching


Comma separated playlist_index of the items to download. You can specify a range using "[START]:[STOP][:STEP]". For backward compatibility, START-STOP is also supported. Use negative indices to count from the right and negative STEP to download in reverse order. E.g. "-I 1:3,7,-5::2" used on a playlist of size 15 will download the items at index 1,2,3,7,11,13,15


Download only videos uploaded on this date. The date can be "YYYYMMDD" or in the format [nowtodayyesterday][- N[dayweekmonthyear]]. E.g. "--date today-2weeks" downloads only videos uploaded on the same day two weeks ago


Generic video filter. Any "Output Template" field can be compared with a number or a string using the operators defined in "Filtering Formats". You can also simply specify a field to match if the field is present, use "!field" to check if the field is not present, and "&" to check multiple conditions. Use a "" to escape "&" or quotes if needed. If used multiple times, the filter matches if atleast one of the conditions are met. E.g. --match-filter !is_live --match-filter "like_count>?100 & description='(?i)& dogs" matches only videos that are not live OR those that have a like count more than 100 (or the like field is not available) and also has a description that contains the phrase "cats & dogs" (caseless). Use "--match-filter -" to interactively ask whether to download each video


Use the mpegts container for HLS videos; allowing some players to play the video while downloading, and reducing the chance of file corruption if download is interrupted. This is enabled by default for live streams


Download only chapters whose title matches the given regular expression. Time ranges prefixed by a "" can also be used in place of chapters to download the specified range. Needs ffmpeg. This option can be used multiple times to download multiple sections, e.g. --download-sections "10:15-inf" --download-sections "intro"


Name or path of the external downloader to use (optionally) prefixed by the protocols (http, ftp, m3u8, dash, rstp, rtmp, mms) to use it for. Currently supports native, aria2c, avconv, axel, curl, ffmpeg, httpie, wget. You can use this option multiple times to set different downloaders for different protocols. E.g. --downloader aria2c --downloader "dash,m3u8:native" will use aria2c for http/ftp downloads, and the native downloader for dash/m3u8 downloads (Alias: --external-downloader)


Give these arguments to the external downloader. Specify the downloader name and the arguments separated by a colon ":". For ffmpeg, arguments can be passed to different positions using the same syntax as --postprocessor-args. You can use this option multiple times to give different arguments to different downloaders (Alias: --external-downloader-args)


The paths where the files should be downloaded. Specify the type of file and the path separated by a colon ":". All the same TYPES as --output are supported. Additionally, you can also provide "home" (default) and "temp" paths. All intermediary files are first downloaded to the temp path and then the final files are moved over to the home path after download is finished. This option is ignored if --output is an absolute path


Template for progress outputs, optionally prefixed with one of "download:" (default), "download-title:" (the console title), "postprocess:", or "postprocess-title:". The video's fields are accessible under the "info" key and the progress attributes are accessible under "progress" key. E.g. --console-title --progress-template "download-title:%(info.id)s-%(progress.eta)s" 2ff7e9595c
