I am planning on seeing if a video taped testimony to be played at
trial would suffice in lieu of actual face to face confrontation with
defendant.
This does not satisfy the confrontation clause. At a minimum, a testifying witness must be subject to being cross-examined by defense counsel. The Confrontation Clause guarantees an opportunity for effective cross-examination. Delaware v. Fensterer, 474 U.S. 15, 20 (1985) (per curiam).
For example, in Melendez-Diaz v. Massachusetts, 557 U.S. 305 (2009), and Bullcoming v. New Mexico, 564 U.S. 647 (2011), the Court ruled that admitting a lab chemist's report of his analysis into evidence, without having him testify, violated the Confrontation Clause. This would have been true even if the chemist had read the report aloud on videotape in response to a prosecutor's questions, rather than putting it in writing and signing it.
There are rare cases where an exception is made to allow child abuse victims to testify live via closed circuit television, rather than in the physical presence of the defendant and the defendant's lawyer.
Remote live testimony is rarely allowed in the case of adults. But technically feasible videoconferencing is a new technological development, so the constitutionality of live videoconference testimony subject to cross-examination remains a largely open issue in constitutional law. This is a particularly close question in Alaska, where there is a state constitutional right to participate in court proceedings and legislative hearings remotely (Alaska is the only jurisdiction in the U.S. to have such a right.)
Still, in the vast majority of cases, in person, live testimony in the courtroom is required as a matter of court rules that apply in criminal cases, whether or not this is constitutionally required.
There are also rare cases where video of an unavailable witness (e.g. a murder victim, or a witness who died before the trial was held) might be admitted in lieu of live testimony, either taken in a non-testimonial fashion, see Crawford v. Washington, 541 U.S. 36 (2004), or as a "preservation deposition" in which defense counsel had a right to cross-examine the witness and the defendant has a right to be present to assist the defendant's counsel, taken when an elderly or infirm or deportable witness is likely to be unavailable at trial.
Most states prohibit the use of preservation depositions in criminal trials when the witness is available to testify, but this requirement isn't necessarily a constitutional confrontation clause issue.
Also, again, neither of these exceptions would apply in the circumstances found in the question.
Footnote Re Hearsay v. Confrontation Clause
The video statement suggested in the question would also violate the non-constitutional court rule of evidence that prohibits hearsay testimony, subject to many exceptions, in most civil and criminal trials.
In a nutshell, the hearsay rule prohibits courts and juries from considering evidence of statements made by someone who is not a party to a case or their co-conspirator or affiliate, that was not subject to cross-examination, offered into evidence to prove the truth of the statement made by that person, unless one of about two dozen exceptions to the rule apply (none of which would be likely to apply under the facts set forth in question).
In the United States, the hearsay rule, and the confrontation clause that applies in criminal cases but not civil ones, heavily overlap. But the two rules excluding certain kinds of evidence from criminal trials are independent of each other and are not identical.
There is some testimony which is not excluded from evidence by the hearsay rule that is still subject to the confrontation clause.
For example, the lab reports that were held to be inadmissible without supporting live testimony from their authors subject to cross-examination in Melendez-Diaz v. Massachusetts, 557 U.S. 305 (2009), and Bullcoming v. New Mexico, 564 U.S. 647 (2011), would often be admissible under the hearsay rule of evidence in a civil case as business records.
Likewise, there is some testimony which is not excluded from evidence by the confrontation clause which is still barred by the hearsay rule.
For example, a statement made in a letter or email or text message by someone who was not a criminal defendant or co-conspirator who is available to testify that was not a business record, that was not intended at the time it was written to be used in a court case or a report to public officials, would still be barred from evidence under the hearsay rule in most cases. But it would not be excluded from evidence by the confrontation clause under Crawford v. Washington, 541 U.S. 36 (2004) because it was not testimonial in nature.
Of course, in a real world criminal case, both the hearsay rule objection and the confrontation clause objection must be satisfied for evidence to be admitted if the defendant's lawyer objects to the admission of the evidence.
