Texas Rules for Civil Procedure # 199.1 section c
Nonstenographic recording. Any party may cause a deposition upon oral examination to be recorded by other than stenographic means, including videotape recording. The party requesting the nonstenographic recording will be responsible for obtaining a person authorized by law to administer the oath and for assuring that the recording will be intelligible, accurate, and trustworthy. At least five days prior; to the deposition, the party must serve on the witness and all parties a notice, either in the notice of deposition or separately, that the deposition will be recorded by other than stenographic means. This notice must state the method of nonstenographic recording to be used and whether the deposition will also be recorded stenographically. Any other party may then serve written notice designating another method of recording in addition to the method specified, at the expense of such other party unless the court orders otherwise.
