NEW DELHI: The role of Shilpi Tewari , who is said to be a close aide of HRD Minister Smriti Irani , has come under sharp focus in the JNU video controversy after a Delhi government-commissioned forensic report found that her twitter account hosted one of the allegedly ‘doctored’ JNU videos The report, which found at least three videos suspect, has labeled the one linked to Tewari as Q 2. The report, accessed by ET, states: "Discrepancies in the lip sync seen in the recordings Q1 and Q2 indicate that the audio stream is not a part of the originally recorded video and hence the conversations heard are not authentic and do not represent true speech by the speakers."Elsewhere, the report states: “The recording Q2 was found to be associated with the user account ‘Shilpi Tewari’ in the social media www.twitter.com.” It eventually concludes with the opinion: “Hence, it is concluded that the recordings Q1and Q2 are not authentic as the audio and video streams are from different sources, merged with an intention to make these recordings appear as representation of true events.”TruthLabs carried out a forensic audio-video authentication study after the Delhi government, as part of its ongoing District Magistrate-led inquiry, submitted five videos on February 18 and two more on February 22. In fact, the report also raises a red flag on another video labelled Q5 as one which does not “represent a true and complete event”.The HRD ministry, responding to queries, distanced itself from Tewari but said that she may be “assisting” Irani on a private basis.“In her private capacity, she may be assisting the HRD minister but she is not on any official assignment. The ministry did offer her a position earlier but she never accepted the position/appointment offered”, Ghanshyam Goel, HRD Ministry Spokesperson told ET.Tewari, on her part, did not respond to queries sent by ET. Nor did she reply to several phone calls and messages. Q1, a 38-second Youtube video, claims to show “exclusive” footage of Kanhaiya “caught shouting anti-national slogans”.The content of the 23-second long video Q2 is unclear due to repeated disturbances but the lab report observes that the audio and video streams were “merged together using media manipulation tools”.
