*379**251Raemon Moore was convicted of malice murder and possession of a firearm during the commission of a felony in connection with the shooting death of Asiel Parker.1 On appeal, he contends that his convictions should be reversed because the trial court erred in **252admitting into evidence video recordings without proper authentication and because his trial counsel was ineffective. Finding no reversible error, we affirm.
Viewed in the light most favorable to the verdicts, the evidence presented at trial shows the following. During the early afternoon of July 17, 2012, two groups of people ran into each other at the West End Mall in Fulton County. Moore, known as "Killer Ray" to his friends, was in one group. Parker was in the other group. During the course of conversation, an argument broke out between Parker and Bailey Harper. Harper, who was with Moore's group of friends, wore a "True Viking" shirt identifying him as a member of the "Good Fellows" gang. After several heated exchanges, Parker and Harper decided to take their argument outside. Eddie Jones, a mutual friend of Harper and Parker, walked with them, trying to keep the peace.
Once outside, Harper took Jones' advice to "let it go" and walked off through the parking lot. Moments later, four shots rang out, and bullets shattered the windows of a Subway sandwich shop. Jones, who was standing a few feet from Parker, testified at trial and identified Moore as the person he saw firing a black pistol at Parker. A witness who was in the parking lot saw people fleeing the mall as a man wearing a blue hat walked from the mall, firing a black pistol toward the sandwich shop. At trial, the witness identified Moore from the mall surveillance video as the shooter. Additionally, Harper selected Moore's photograph from a police photographic line-up and gave a statement to investigators identifying "Killer Ray" as the shooter, although he later recanted his identification at trial. Immediately after the shooting, witnesses saw Moore get into the passenger side of a silver or light-colored car that sped away from the mall. Parker, fatally wounded by two of the bullets fired, died later that day at Grady Hospital.
After the shooting, investigators took witness statements, gathered physical evidence, and obtained security camera video **253recordings from the West End Mall. After Harper told an investigator that "Killer Ray" was in a gang called Good Fellows, the investigator sought the assistance of a detective with the Atlanta Police Gang Intelligence Unit to find the shooter. The detective found two rap videos on YouTube showing Moore in his "Killer Ray" gang persona. These videos, which were played for the jury, showed Moore and others rapping while wearing True Viking clothing that identified them as members of the Good Fellows gang. Through these videos, the expert was able to identify "Killer Ray" as Raemon Moore and to obtain his phone number. The expert opined at trial that Parker's murder constituted criminal gang activity because Moore likely shot Parker for showing disrespect to Harper. After witnesses came forward identifying Moore as *380the shooter, investigators took out a warrant for his arrest. During a traffic stop on August 15, 2012, an officer arrested Moore.
1. Moore does not dispute the legal sufficiency of the evidence supporting his convictions. Nevertheless, as is this Court's practice in murder cases, we have reviewed the record and conclude that, when viewed in the light most favorable to the verdict, the evidence presented at trial and summarized above was sufficient to authorize a rational jury to find Moore guilty beyond a reasonable doubt of malice murder and possession of a firearm during the commission of a felony. See Jackson v. Virginia , 443 U.S. 307, 319 (III) (B), 99 S.Ct. 2781, 61 L.Ed.2d 560 (1979). See also Vega v. State , 285 Ga. 32, 33 (1), 673 S.E.2d 223 (2009) ("It was for the jury to determine the credibility of the witnesses and to resolve any conflicts or inconsistencies in the evidence." (citation and punctuation omitted)).
2. Moore contends the trial court erred in admitting into evidence video recordings that were not properly authenticated. Specifically, he challenges the admission of the YouTube rap videos and the mall surveillance videos.2 "We review the trial court's decision to admit **254evidence for an abuse of discretion." (Citation omitted.) Bolling v. State , 300 Ga. 694, 698 (2), 797 S.E.2d 872 (2017).
(a) YouTube video recordings . Moore contends that the admission of unauthenticated YouTube videos offered in support of the criminal gang activity charge was harmful and requires the reversal of all of his convictions.3 We disagree.
At trial, the State called a detective with the Atlanta Police Gang Intelligence Unit to testify. The detective was accepted by the trial court as an expert in criminal street gangs and gang activity. The detective testified about a street gang known as Good Fellows or "GF," a group he investigated in relation to this case and the count of criminal gang activity. The detective testified that, based on his research, which included interviews with known gang members and crime victims, he learned that "Killer Ray" was Moore's gang moniker and that Moore and Harper were both members of Good Fellows. In support of the detective's testimony, the State presented the YouTube videos and a few still images taken from those videos. The detective testified that he found the YouTube videos when searching the Internet for information on "Good Fellows" and "Atlanta." The detective noted that, in the recordings and still images, Moore and Harper wore clothing identifying them as affiliates of Good Fellows. Further, the imagery and graffiti "tagging" in the videos as well as rap lyrics sung by Moore and others were intended to "show everyone who they are" and to intimidate the public, rival gangs, and even fellow gang members who might break their code of silence.
At trial and in the order on Moore's motion for a new trial, the trial court found that the State had laid a sufficient foundation for the admission of the videos. Although the trial court ultimately set aside Moore's conviction on the charge of criminal gang activity, it did *381so based on its finding that the evidence failed to show the requisite "nexus between [Moore's] crimes and furtherance of [the gang's] interests[,]" not that the video evidence was unauthenticated. The trial court also found that "even if some of the gang evidence was admitted in error," it was highly probable that any erroneous ruling by the trial court with respect to Moore's criminal gang activity did not contribute to the verdict. **255Pretermitting whether the trial court properly found that the YouTube videos and related still images had been properly authenticated, any error in the admission of that evidence was harmless to Moore on the counts of malice murder and possession of a firearm during the commission of a felony, the crimes for which he was convicted and sentenced. Several eyewitness saw Moore at the scene of murder, one saw him shoot Parker, and several witnesses were able to identify him as the shooter from the mall surveillance videos. Considering the strong evidence that Moore shot Parker to death, we conclude that it is highly probable that any erroneous evidentiary ruling by the trial court with regard to Moore's criminal gang activity did not contribute to the jury's verdicts. See Brown v. State , 300 Ga. 446, 447-448 (2), 796 S.E.2d 283 (2017) ; see also Smith v. State , 299 Ga. 424, 431-432 (2) (d), 788 S.E.2d 433 (2016) (explaining that OCGA § 24-1-103 (a) of the new Evidence Code continues the preexisting harmless error doctrine in Georgia). As such, Moore's contention that his convictions must be reversed has no merit.
(b) Surveillance video recordings . Moore did not object to the admission of the mall surveillance video recordings and still photographs taken from those videos at trial. Where an appellant fails to make an objection to the admission of evidence in the trial court, the claim of error is not preserved for ordinary appellate review. See OCGA § 24-1-103 (a) (1) ; Anthony v. State , 302 Ga. 546, 549 (II), 807 S.E.2d 891 (2017) ("An issue that is not presented or ruled on by the trial court is not preserved for appellate review." (citation and footnote omitted)). Thus, we may review Moore's claim, but only for plain error. See OCGA § 24-1-103 (d) ("Nothing in this Code section shall preclude a court from taking notice of plain errors affecting substantial rights although such errors were not brought to the attention of the court."). To satisfy the test for plain error, Moore must show, among other things, the existence of an error. Wilson v. State , 301 Ga. 83, 88 (2), 799 S.E.2d 757 (2017). Moore failed to make that showing.
Under Georgia law, "[g]enerally, a videotape is admissible where 'the operator of the machine which produced it, or one who personally witnessed the events recorded[,] testifies that the videotape accurately portrayed what the witness saw take place at the time the events occurred.' " Sowell v. State , 327 Ga. App. 532, 536 (1), 759 S.E.2d 602 (2014), quoting Phagan v. State , 268 Ga. 272, 281 (5), 486 S.E.2d 876 (1997) (punctuation and footnote omitted).4 See also **256Birdsong v. Barnett , 334 Ga. App. 120, 778 S.E.2d 372 (2015) (A video recording was properly admitted under OCGA § 24-9-923 (c), as the complaining witness testified that she personally transferred the video from her home security system to the disc she presented to the court and that the video accurately depicted the incident on the date in question.).
In this case, the record shows that the State presented the testimony of eyewitnesses to the events to authenticate the two mall surveillance video recordings, State's Exhibits 3 and 4, and the still images taken from them. With respect to State's Exhibit 3, an eyewitness to the shooting testified that the video accurately depicted the mall and Subway sandwich shop next door to the make-up studio where she was working on *382the day of the shooting. The video also accurately showed the movements of several people, including herself, who were involved in the events associated with the shooting. With respect to State's Exhibit 4, a witness testified that she was familiar with the video, had viewed it prior to trial, and that it fairly and accurately depicted what happened on the day of the shooting, including the movements of the individuals involved in the shooting, including herself. Several still images taken from the videos also display date and time stamps that correspond to witness testimony about the date and time of the shooting. Given that the State adduced evidence sufficiently authenticating the mall surveillance videos, they were admissible. Thus, Moore has failed to show error - much less, plain error - in the court's admission of that evidence.
3. Moore contends that his trial counsel's failure to object to the admission of the video evidence discussed in Division 2 deprived him of the effective assistance of counsel. To prevail on his claim of ineffective assistance of counsel under Strickland v. Washington , 466 U.S. 668, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984), Moore must show both that counsel's performance was deficient and that the deficient performance prejudiced his defense. To prove deficient performance, he "must show that his lawyer performed at trial in an objectively unreasonable way considering all the circumstances and in the light of prevailing professional norms." Romer v. State , 293 Ga. 339, 344 (3), 745 S.E.2d 637 (2013). The prejudice prong requires a defendant to show "a reasonable probability sufficient to undermine confidence in the outcome that, but for counsel's alleged unprofessional errors, the result of the proceeding would have been different." (Citations and punctuation omitted.)
**257Miller v. State , 285 Ga. 285, 286, 676 S.E.2d 173 (2009). "If an appellant fails to meet either prong of the Strickland test, it is not incumbent upon this Court to examine the other prong." Dunn v. State , 291 Ga. 551, 553 (4), 732 S.E.2d 524 (2012).
In this case, Moore has failed to show that his trial counsel's performance was deficient. Contrary to what he claims in his brief, the record shows that counsel objected to the YouTube videos. Further, even though he posed no objection to the mall surveillance videos, the record shows that they were properly authenticated and that the trial court would have been authorized to overrule an objection on this ground based on the evidence presented by the State. See Duvall v. State , 290 Ga. 475, 477 (2) (b), 722 S.E.2d 62 (2012) (trial counsel cannot be deficient for failing to lodge a meritless objection). Consequently, given that Moore has failed to show deficient performance, the trial court correctly held that he failed to show ineffective assistance of trial counsel. See Romer v. State , 293 Ga. at 344 (3), 745 S.E.2d 637.
Judgment affirmed.
