Vídeo não funciona

Hello @valeria_9397 

Let me ask some questions as we try to reproduce the problem:

• Can you describe your original video: what is the camera and file type; 1080p or 4K, captured as HDR? etc
• What kinds of edits are applied to your video?
• How long is the video (in seconds)?
• To get it from Lightroom to Instagram, are you using the Lightroom Share > Instagram menu?
  
  • If so, does it help to export to your camera roll using Share > Export As... MP4, or Share > Save Copy to device? And then import into Instagram from your camera roll?
