I'm new here and I'm trying to post an animation but I keep having the error "error: ActiveRecord::RecordInvalid - Validation failed: File ext is invalid (only JPEG, PNG, GIF, and WebM files are allowed, File size is too large. Maximum allowed for this file type is 0 MiB"
The original file is mp4 and i've tried different converter to webm but none seems to be accepted.. If you could tell me how to convert a mp4 video in webm without losing quality that would be helpful
