42

Version 42, 11 April 2024

Notable changes in this release:

• Fixed potential issue where audio and video could be dropped if the game is significantly faster than the encoding. This would not necessarily have happened in a real world scenario.
• Small performance improvements.
• Video time and elapsed real time are now shown in the window title and the task bar.
• New parameters have been added to the startmovie command, which allows you to control various things about the current rendering.
• Added a rendering timeout option to the startmovie command, to automatically stop the movie after the video time reaches a certain time (region rendering).
• Added a progress bar to the game taskbar icon if rendering timeout is enabled.
• The startmovie command now has a new syntax for optional parameters.
• Fixed all output being blurry.
• Added profile inheritance. You now no longer need to copy the default profile, instead you can override individual settings from the default profile.

Movie start changes

The format of the startmovie command has changed a little bit in this release to allow additional parameters. These parameters can be used to control the profile, autostop region rendering and some other things (see here). The parameters can appear in any order and all are optional. See the link for all parameters and their values.

The startmovie command should now be used like this:

startmovie <file> (<optional parameters>)

As an example:

startmovie movie.mov timeout=30 profile=my_profile

The above command will automatically stop after 30 seconds of rendered video, and use the my_profile.ini profile.

Profile changes

Profiles are also now inherited from the default profile, which means you do not have to copy the default profile anymore to create new profiles. Instead you can just override the individual settings that you want to change.

As an example, a new file called my_profile.ini with content:

motion_blur_enabled=1

Region rendering

A timeout parameter has been added to the startmovie command which allows rendering to automatically stop after the rendered video time in seconds have elapsed. You can use it like this:

startmovie movie.mov timeout=30

When region rendering is enabled, the taskbar icon of the game will change to report the region rendering progress, rendered time and elapsed time:

Quality changes

Below images show the quality differences between earlier versions and version 42. Earlier versions of SVR has had a bug in the output which produced blurry video. Antialiasing has been disabled for below screenshots.

SVR 41

Version 41, 20 March 2024

Notable changes in this release:

• Added a 64-bit external process that encodes the data from SVR. This comes with a performance boost, but also allows audio and video to be embedded in the same file.
• Added an option to use the DNxHR video encoder. This codec works a lot better in video editors, and also has slightly better color information through YUV422 over NV12.
• Changed the default video encoder to use DNxHR.
• Added an option to select the audio encoder to use. At the moment there is only AAC (through aac_mf).
• Added an option to use the YUV444 format with x264, selectable through the libx264_444 video encoder in the profile.
• Velo text is now using the tabular font feature which means text will not jitter for fonts that use varying number widths. This would typically happen with the number 1 which can be thinner in some fonts, causing the text to jitter in width.
• Changed the default velo font format to a better default.
• Added velo text opacity.
• Added velo_anchor option which allows to set the text expansion direction.
• Velo is now by default in the lower left with an anchor of left.
• Added velo_length option which allows to set the axes of velocity to show.
• Fixed motion blur blending working in the wrong color space. Blending is now done in the linear color space. Previously blending was done in a non-linear color space which meant some colors would blend together too dark.
• Fixed color space issues.

Performance has been improved a lot in this release, as well as fixing various color related problems. Below you can see a comparison of motion blur blending in previous versions and this release. Encoding now also uses a wider color space to more accurately represent the original color, also visible below.

Various changes have been done to velo to skip text jittering, typically seen with the '1' character having a thinner width in some fonts. Opacity for velo color has been added back again after being removed by mistake. Some additional velo options have been added too, letting you select an anchor point for text expansion as well as ability to select which speed to show per axis. New default font and font options have been set as well in the default profile.

Most typically you will produce content using SVR to place it in a video editor. A new encoder called DNxHR has been added which makes this workflow a lot better, since H264 is overly compressed to be used efficiently during editing. You can still use H264 if you intend to not perform additional work on the content. Note that DNxHR can not be used with the MP4 format, so you will need to use MOV or MKV.

With the introduction of a separate encoder process, this means that audio and video can be embedded in the same file as expected. This was not possible before for various reasons. An audio encoder can be chosen as well, but there is only one at the moment.

See the default.ini profile for documentation about the new options.

SVR 35

Supported games in this release:

• Counter-Strike: Source
• Counter-Strike: Global Offensive
• Team Fortress 2

Notable changes in this release:

• Steam games are automatically scanned for by the launcher and no manual setup needs to be done.
• Sound is now included as a new fast technique has been found for all games.
• Performance has been improved by a lot (20%+).
• Velocity text performance has been improved by a lot (34%+).
• More helpful error messages.
• Profiles are now in a INI style format that allows comments and does not have escaping nonsense and format nonsense as JSON (easily editable).
• Hardware support is checked in the launcher. SVR cannot be used if the hardware is not supported.
• Launch parameters to use in the launcher is read from Steam (needs Steam to be running).
• Logging is now done to SVR_LOG.TXT, and not a hard to use console window (but the launcher still uses it - things are logged to both). This text file can easily be shared and contains useful information.
• Identifying information about the graphics adapter and HW/OS is now logged for troubleshooting hardware issues.
• The launcher now stores information about the tested game builds so we can see if the installed game version differs from the tested version (a warning will be logged).
• Autostarting a game still works the same as before, by using "svr_launcher.exe <app_id>".
• The profiles have been made simpler and the documentation for each setting is included in the profile file directly.
• The video pixel format is now chosen from the encoder, and is not settable.
• The video color range is no longer settable.
• The number of encoding threads now always matches the number of cores in the system.
• Multiprocess rendering has been removed as Source works really weird when the same game is launched multiple times with the same game directory.
• Optional border has been added to velo text.
• Velo text is now aligned by screen percentages to allow any resolution independent position to be used.
• Velo character spacing has been removed.
• Game config and launcher config have both been removed. Launcher config has been replaced by the launcher doing the work automatically. Game config has been replaced by code directly to ease development and reduce scope.
• Custom launch parameters are now in a file called svr_launch_params.ini.
• An update.cmd file has been created to easily download the latest version (needs manual unzip).
• SVR now supports both D3D9Ex and D3D11 games.
• It's now possible to apply or override user settings when a movie starts or stops recording. These files are svr_movie_start_user.cfg, svr_movie_end_user.cfg, svr_movie_start_<app_id>.cfg, svr_movie_end_<app_id>.cfg.
• If no extension is written when starting the movie, .mp4 will be set.
• avi and mov are no longer allowed containers as they are outdated that do not support various encoding features.
• A big message is now written in the console when SVR is initialized, to show that it has loaded.
• There is now an SVR API that can be used for direct game integrations (Momentum in the future).
• Recording will now automatically stop when demo ends or client disconnects.
• Various other fixes and performance improvements.

Please read the readme before using this version!
