    I've been using the Unity Recorder to create small videos of gameplay from within the editor for some time without any problems.
    Yesterday I added some ui components to the game and recorded a video, but found that the Text components are not appearing in the video recorder (nor the game editor tab when recording). Other ui components such as images and panels are visible.
    When not using the recorder, the text appears ok.
    Any ideas on how to solve this?
    I'm using Unity 2021.x and Uniy Recorder 2.5 installed from the package manager. I've found a similar bug from 2017 (not saying it's the same) , back when unity recorder was on github. It was solved in 0.02, don't know whether it's related https://github.com/Unity-Technologies/GenericFrameRecorder/issues/11

    Hello, I am going to investigate this issue. Here are a few questions:
    * Which Render Pipeline are you using?
    * Which package are you using for building your UI? I'm guessing this is Unity UI @ 1.0.0
    * Can you please share a screenshot of your Recorder settings? I assume you're recording the GameView.

    Also, we released 4.0.0-pre.1 recently, you should upgrade :)

    I just tried in 2021.1.15f1 with Recorder@4.0.0-pre.1 and I can see my text in the export, both images and movies (WYSIWYG, if it shows up in the GameView you should see it in the export).

    Can you try a very simple canvas setup like mine?

    I'm using the builtin render pipeline, unity 2021.1.15f1, unity ui 1.0.0, and recorder 2.5.5.
    Unity recorder 4.0.0-pre.1 looks like only supports HDRP? I don't think I'll be able to update to that version in this particular project.

    Later today I'll create a setup like you did and test it.
    Thanks

    Found the problem, it's not related to Unity Recorder.
    I'm recording with an "output resolution" different than "Match window size". So, when Unity Recorder starts, it changes the game windows size -> changes aspect ratio -> the ui elements disappear.
    Changing "output resolution" to "Match window size" works.

    So, it's something in my code (haven't solved it yet!).
    Thanks

    FYI Recorder never "only" supports HDRP. It works for all render pipelines, it's just that some features are only available with HDRP > version X.Y.Z. (namely AOV recorders).

    Had something similar today with Recorder in 2020LTS. It's fully down to the bad design of Canvas and how it adapts to different resolutions - any UnityUI element or layout that had a 'size' will break when Recorder switches resolution (Canvas only works correctly on resolution changes if everything had 0 size and was fully dynamically resized to fit parent object).

    Best approach is to discard/bypass/ignore CanvasScaler and write your own solution that works sanely and sensibly for resolution changes, and then these problems go away (used to be some open-source ones floating around).

    TL;DR: Recorder isn't at fault here, it merely shines a light on Canvas's poor design.
