TASRecorder

Create frame-perfect TAS recordings

A convenient way for you to record a TAS. If you've used .kkapture before, or struggled to get it working, this tool is perfect for you!

And if you've used ldcapture, this might feel familiar. That's because this is more or less a direct port of ldcapture, however in an easier to use and more cross-platform way.

Installation

Just install it with Olympus or mons. Alternatively you can download the .zip directly from Gamebanana or from the Github Releases.

Requirements

• Atleast Everest 4465
• FFmpeg libraries (avutil, avformat, avcodec, swresample, swscale) (Installed by TAS Recorder if not present)
• FFmpeg binary (Installed by TAS Recorder if not present)
• (Optional, but very recommended) CelesteTAS for easier recording

NOTE: If you are on MacOS/Linux (x86-64), it is strongly recommended to install the FFmpeg with your system's package-manager!

You can use the debug console command ffmpeg_check to verify that the FFmpeg is working correctly. In case this fails, make sure to check your log, to find out what went wrong!

Usage

All recordings will be saved to TAS-Recordings in your Celeste install folder. This can be changed in the mod options.

Recording entire levels

In Celeste Studio, you can go to File and then Record TAS. Note that this will simply record all inputs and stop after that. You probably want to add additonal frames after the end, for a smooth ending (see below for common endings). If the TAS ends, because it goes to the overworld, the recording will finish.

In case you can't use Celeste Studio, the same can be achived with the following:

#console load ...
#   1
   1,Q
  32,J
StartRecording

#Start
...

ChapterTime: ...

The quick restart is used to restart the music (NOTE: The Record TAS button already does this). This can be replaced with the console load if you don't care about that.

To achieve a good looking level ending, there are a few snippets. Just paste those inputs after ChapterTime. If your ending isn't included, you'll have to do it yourself.

Recording Segments

If you just want to record certain segments of a TAS, you can use the StartRecording and StopRecording commands. Everything between those commands will get recorded. The file name is the current date and time.

Additional Features

Speeding up certain segments

If there are any boring / uninteresting parts of your TAS, you can speed them up with the following command:

Set, TASRecorder.Speed, 2.0

This means that from that point on, the recording will play twice as fast. Any value (except 0) is technically supported. 1.0 is normal speed, 0.5 is half speed, 2.0 is twice the speed, and so on. Note that anything beyond 10.0 becomes quite difficult to watch so it's not really recommended.

While the video is sped up, audio stays at the normal speed. However with high speeds, sound effects can become quite loud and unpleasant to hear. Therefore it is recommended to mute sound effects during high speeds with the following command:

Set, TASRecorder.MuteSFX, true

This can be reverted by setting it to false again.

Both those settings will get reset once the recording has finished and must be set after the recording has already started.

Black Fades

You can fade the entire screen to black with the following command:

Set, TASRecorder.BlackFade, 1.0

The 1.0 means that the fade-out will take 1 second.

To revert the fade, you can usage negative numbers. The absolute value specifies the the duration:

Set, TASRecorder.BlackFade, -1.0

There are a few settings which you can configure. They are only reset when you start recording:

• Set TASRecorder.BlackFadeText This is some example text The text to display (NOTE: Due to the way set commands work, you'll have to use a single space as separator or you could experience some weird issues with the text)
• Set, TASRecorder.BlackFadeTextPosition, 400, 600: Center-position on the screen in pixels, assuming a resolution of 1920x1080. 960 540 (screen center) is the default. (NOTE: This also works in other resolutions, but always uses 1920x1080 for positioning)
• Set, TASRecorder.BlackFadeTextScale, 3.1415: Size of the displayed text. 1.0 is the default
• Set, TASRecorder.BlackFadeTextColor, 90, 255, 130: Color of the displayed text. 255 255 255 (white) is the default. (NOTE: Colors are created from 3 RGB values between 0 and 255)

Recording RTA

This is not really recommended, since the frame rate is not locked to 60FPS, but rather the speed at which you PC can record all frames.

This is however capped at 60FPS, unless you are recording without audio, in which case, doesn't have a frame rate cap.

The debug console commands work basically the same as the TAS commands but are available outside of TASes: start_recording and stop_recording.
