How to reproduce?

VideoRenderData(
  videoSegments: segments,
  enableAudio: true,
  qualityConfig: VideoQualityConfig.custom(
    bitrate: 8000000,
    resolution: Size(1080, 1920),
  ),
  outputFormat: VideoOutputFormat.mp4,
)

When rendering with the settings above, using a 720x720 video results in a 1080x1080 output. In my opinion, in this case, the 1080x1920 output should have the video in the center using "contains fit," and the remaining space at the top and bottom should have black padding.

Below are three videos made with the same settings.

1. 720x720 1 clip

2. 720x720 + 1080x1920 2clip merge

3. 1080x1920 + 720x720 2clip merge -> I think this output is normal, as expected.

@hm21 Is there a target schedule for fixing this issue? I am not trying to rush you, but I would like to establish my own plan for when it can be resolved.

@choim4389 unfortunately not. I always try to fix issues as soon as possible, but at the moment I’m very busy with another project and haven’t had time to take a look yet.
