The issue occurs due to keyframe intervals in the video file. Players can only seek to the nearest keyframe. Re-encode the video with shorter keyframe intervals or use a precise player like VLC.

YouTube only supports one audio track per video. Combine tracks in editing, upload separate versions, or use subtitles for multiple language options.

To use noise cancellation in Action!, go to Settings > Audio, and enable Noise Suppression. Adjust the suppression level as needed to reduce background noise during recordings and streaming.
