Cannot export video file in correct resolution
From your question, you want to remove the audio from a video clip, using Premiere.

Start a new sequence, and drop your clip into it. There should be audio and video streams in the timeline.

Using File &gt; Export &gt; Media, there is a very simple way to remove the audio.



Using these toggles here, you can disable audio from being included in the export.

However, you will also want to make sure that your export settings are the same as the video clip.



As for setting a codec, I suggest either:


Format: QuickTime / Codec: Animation - if you need a high-quality, large file size video for further editing.
Format: QuickTime / Codec: H.264 - if you need a file ready for playback, distribution, or internet upload.
