Video Unity Recorder update

Hi @chafik_unity

I was able to reproduce the issue by doing this:

1. Create new project in 2018.2.3f1
2. Add Unity Recorder from Asset store
3. Add Cinemachine from Package manager (Import step here)
4. Hit record on the default scene and watch the frame rate issue.

I noticed it wasn't an issue until I added Cinemachine into my project.

Let me know if you can't reproduce this and I can send you my project.

Thanks
Jeff.

 

Hi I am unable to record worldspace UI in 360 videos. Any fixes for that?

 

Thank you! This worked for me!

 

I really love the recorder and I have been wanting to use the Recorder for recording particle simulations, but I cannot get the recorder to record the alpha from particles. It works fine with 3d objects. Am I overlooking something ? Any chance you could fix that?

 

I've download Recorder from the asset store but am getting this error when trying to open Tools>Recorder>Video

Parent directory must exist before creating asset at Assets/Unity/Sol/Assets/Unity Technologies/Recorder/RecorderWindowSettings.asset.

AddAssetToSameFile failed because the other asset is not persistent

Any suggestions?

 

Were there any updates on the recorder completely choking after getting around 2 seconds of MP4 clip saved? This makes our work excruciatingly slow, and there hasn't been any clarification or fix for this for a very long time - not on GitHub, not in the package manager, and not in the Asset Store.

 

Out of curiosity, is there a reason why the Recorder went from open to closed source? My immediate guess would be private/proprietary plugins/codecs, but if it's something else I'd be interested to know.

 

Hi can we have in Recorder Editor https://docs.unity3d.com/ScriptReference/Cursor-visible.html

Would be very handy. Thanks. Marek.

 

Thanks, this works!

 

Hi Unity, the recorder is awesome, however i've noticed an issue when saving as 8k frames - every so often, a random frame will glitch during the rendering. It only happens with 8k frames - 5k frames, or 4k frames / .mp4 don't exhibit the same behaviour.

The glitch is kinda strange, like a series of concentric coloured circles - I've attached a cropped image to show this.

 

Bugger,

My project is running 2017.4. I don't want to risk the migration. The asset store states that RECORDER supports 2017.1 and higher

Is there no other way around this?

 

I'm running version 1.0.2 of the Unity Recorder with 2018.2.7 Unity on WIndows 10. I can record mp4 no problem, but when I try and record frames (jpeg, png, exr) I just get black frames.
Any ideas?
Thanks,
Jeff

 

update... I was able to render correctly to files as long as I had Game View selected in the capture field. I previously had targeted camera / Main camera selected and that did not work. Not sure why.

As we design a hybrid audio game, we could need that recorded sound is hearable during play in editor.
As soon as i hit the record button sound is routed to recording and not hearable any more.

I have a question about using the recorder on Windows 7. I'm trying to record a 4K mp4, and I'm having the same problem that was outlined in this thread: https://forum.unity.com/threads/video-decoding-windowsvideomedia-error-0xc00d36b4.456960/

Apparently, the built-in H.264 decoder in Win7 doesn't support anything above 1080p. Is it possible to work around this by installing a different codec, or is the issue internal to the OS and basically can't be fixed? Even if I did install a codec, I'm not sure how to tell Unity to use that one instead of the built-in one.

 

Is there any way to make pull requests to the "new" Recorder living in the AssetStore? There are still bugs + improvements to be made, I'd be willing to do so myself and create a Pull Request, but couldn't find a repository.

Feature Request: to clarify, simple stuff like adding some more useful wildcards that are properly sorted in any file browser (e.g. "Timestamp", aka DateTime.Now.ToString("yyyyMMdd-HHmmss"), would certainly be community-contributable...

Feature Request 2: Would be great if capturing single images didn't require Play Mode to be active.

Bug Report 1: recording single frames from code only works a single time and throws an exception while doing so. Play Mode needs to be restarted afterwards. The example is unhelpful since it's recording a sequence.

After some more testing:
controllerSettings.SetRecordModeToSingleFrame(0); is buggy. What does work (but freezes the image for far longer than a single frame) is controllerSettings.SetRecordModeToSingleFrame(1);

Bug Report 2: StopRecording has to be called even if the recording has already stopped automatically (due to single-frame recording), resulting in really weird code necessary to not get any exceptions:

Code (CSharp):

1. public void MakeScreenshot()
2. {
3.     imageRecorder.outputFile = mediaOutputFolder + "/screenshot_" + GetTimestamp();
4.     recorderController.StartRecording();
5.     StartCoroutine(_StopRecording());
6. }
7.  
8. IEnumerator _StopRecording()
9. {
10.     // note that we need to wait until the recording is done before stopping it. Weird!
11.     // without this coroutine, the next call to "MakeScreenshot" causes an exception.
12.     while (recorderController.IsRecording())
13.         yield return null;
14.     recorderController.StopRecording();
15. }

Improvement Request: Saving a Preset for single-frame recording shows a yellow exclamation mark with "Invalid frame rate" in the Inspector.

 

I just downloaded this and set up a bunch of gif and image sequence recordings in Timeline. When I play the scene two unfortunate things happen. First everything but the UI background and particle systems turn white (see attached image) in the image sequences. Second the GIF sequeneces don't export at all. I do get DLLNotFoundException: fccore on every frame when it tries to record a GIF. Any thoughts as to what is going on?

I am running Unity 2018.2.6f1 on mac.

 

Nope that didn't work. I deleted Assets/Unity Recorder, removed all the recorder clips from the Timeline, re-imported the unity package from the asset store, set up one GIF recorder and still get the same error.

The image sequence export now works. I also tested an MP4 movie and that works as well. I only get the error with the GIF recorder. I tried a few different settings for the GIF recorder (active vs main camera, output resolutions, max tasks) and none made a difference.

For now I can do a work around where I make MP4's and then use another program to turn them into GIFs. But I'd like to know how to get this working for future projects. Below are the full read outs of the errors I get.

On every frame of recording:
DllNotFoundException: fccore
UnityEditor.Recorder.GIFRecorder.RecordFrame (UnityEditor.Recorder.RecordingSession session) (at Assets/Unity Recorder/Editor/Sources/Recorders/GIFRecorder/GIFRecorder.cs:41)
UnityEditor.Recorder.RecordingSession.RecordFrame () (at Assets/Unity Recorder/Editor/Sources/RecordingSession.cs:129)

At the end of the recording clip:
DllNotFoundException: fccore
UnityEditor.Recorder.FrameCapturer.fcAPI+fcGifContext.Release () (at Assets/Unity Recorder/Editor/Sources/Recorders/_Legacy/FrameCapturer/Scripts/Encoder/fcAPI.cs:253)
UnityEditor.Recorder.GIFRecorder.EndRecording (UnityEditor.Recorder.RecordingSession session) (at Assets/Unity Recorder/Editor/Sources/Recorders/GIFRecorder/GIFRecorder.cs:23)
UnityEditor.Recorder.RecordingSession.EndRecording () (at Assets/Unity Recorder/Editor/Sources/RecordingSession.cs:114)
UnityEditor.Recorder.Timeline.RecorderPlayableBehaviour:OnBehaviourPause(Playable, FrameData)

 

Hello,Im try to capture the particles effects as image sequence with alpha ON but I'm getting output blank. For making sure that Im getting black o/p I have also added a capsule and attached the screen Shots.
I have tested with multiple setting with Targeted Camera and main camera source and Capture modes including Targeted Capture ,360 capture and texture sampling. I'm using 2018.2.0f2(64bit).

If Im missing something please tell me. If this is not included in the feature of 'Unity recorder' please tell me.
Also there are no tutorials available in English.

Edit: My mistake the verson I tested on was 2018.2.0f2(64bit) .

 

I am on 2017.4 (as I presume a huge amount of people are, given that this is your only LTS release and 2018 is still not ready for production work).

How do I download version 0.2? The current version on the Asset Store requires 2018.1. and up.

Why doesn't the Asset Store allow older versions of assets to be downloaded?

 

When I re-downloaded last week, it did give me 0.2, I am using 2017 as well.
Have you tried downloading, it may choose which one you can use so if you are on 2017, it downloads the correct one.

 

Yes I was given the new version automatically I also worked out that I can just set a custom resolution in my game window, and then record the window in Unity Recorded (I was trying to record a 21:9 ultrawidescreen image, which Unity Recorded did not have as an option for aspect ratio).

 

Unity Recorder is producing some very bad quality videos when using the 360 option:


You can see an example of the output here:

Does anyone have any pointers on how to improve quality?

 

I'm having bad quality output in 2D 1080p, not sure why. I've used it in the past and had great video and sound. Now I'm getting poor video and only some sound.
Not sure why. You are not alone...

 

@chafik_unity et all,
I'm using the Unity Recorder and it's quite fabulous. One thing I'm wondering is whether there's an API/scripting manual page somewhere so I can hook this into an app and use it outside the editor, say in a live android app?
Thanks for pointing me in the right direction.

 

^ On second thought, is this the scripting API related to Unity Recorder's functions? https://unitytech.github.io/unity-r...der.FrameCapturer.BaseFCRecorderSettings.html

 

@chafik_unity In other news, I have the settings for the Unity Recorder as shown in the screenshot attached, and it works wonderfully for capturing a single frame, rendered to a rendertexture, but it's flipped vertically. The documentation seems to indicate there should be a "flipped image" button to flip the final image saved, but I think that "Video">UTJ>LEgacy>OpenEXR doesn't have the flip option, while the other options do have it.
Is there any way to get it added ? Would save me a bunch 'o time and brain power...

 

Is there a way to force recording to stop automatically after a time period or frame count?
I’m trying to make a video of a cutscene and need it to end with the music.

 

@dsilverthorn While recording in video mode, I use the "Bounds/Limit" area at the bottom of settings, and choose Mode: Single Frame, (and there's more options) to limit how much is recorded, then it stops automatically. (When used in these steps: Click Play within Editor, Click Record on the Recorder window/tab, it records, and stops automatically, (However the Play mode is stopped as well, just an fyi.)
Keep on Creating!

 

I'll give that a try.

Thanks for the tip!

 

Worked like a charm! I gave it a try and it was perfect!

Thanks again!!!

 

Hey, i just hacked a SaveBytesThreaded Thread for the Recorder, it increase the write speed drastic

add this to ImageRecorder.cs inside the namespace bracets:

Code (CSharp):

1.  
2. class SaveBytesThreaded
3.     {
4.      
5.         public byte[] bytes { get; set; }
6.         public string path { get; set; }
7.      
8.  
9.         public void StartThread()
10.         {
11.             new Thread(SaveBytes).Start();
12.         }
13.  
14.         void SaveBytes()
15.         {
16.             File.WriteAllBytes(path, bytes);        
17.         }
18.     }
19.  

And modify the File.Write in the RecordFrame function to this:

Code (CSharp):

1.  
2. SaveBytesThreaded sbt = new SaveBytesThreaded();
3. sbt.bytes = bytes;
4. sbt.path = path;
5. sbt.StartThread();
6.  

Also add on top:

Code (CSharp):

1. using System.Threading;

 

hi all.

Do any of you also experience a LOSS OF PARAMS on the recorder ?
i set some params on recorderClip, i save the scene and project..

then if at some point i do "mute track" all the settings set for later are lost.
is this a bug ?

 

Hi

i got some sound in record look stop ?


and possible to know video.url.length ?

 

i have try add

if (audioInput.audioSettings.preserveAudio)

but sound it's not played so the Visualizer Studio can't make the job in backround

 

Is there a way to set the sample rate of the recorded audio? The system sample rate in the audio manager doesn't have any influence on that.. any ideas?

 

I tried the OpenEXR Image Sequence Recorder and while it works great, I have a question.
I set my Colorspace to Linear and my Camera has HDR enabled, I am using a Rendertexture to render, with its format set to ARGB Float, which in my head should allow for HDR values (>1) however when I look at my frames in my Editing Software, all colors are clamped at 1 (see attached image).

Am I missing something?

 

Play mode becomes incredibly slow when I start a video recorder with 1080p resolution. The game is so slow (about half speed) that I am unable to record a realistic gameplay. 720p also slows down play mode (about 1.5 second is required to progress 1 second in game). Only lower resolutions (480p and lower) don't impact game speed too significantly.

Does everyone experience this or is it just me?

Because of that issue, recording a standalone build with OBS at 1080p appears to be a better alternative than Unity Recorder.

 

I get the same thing. So I only record cut scenes since mine records only about a frame a second.
