EVIDENCE 3:
ANALYZING THE POSITION OF THE STIRRER (PIPET) WHILE REDUCING THE FRAME DIMENSIONS FROM 1920x1080 PIXELS TO 960x576 PIXELS

Christopher Hariman Rianto deliberately cut CCTV 7 footage just before Mirna Salihin arrived at Olivier café at 17:18 Local Time:

Segment 1: 15:57 – 17:17 Local Time
Frame dimensions remain full high definition (FHD, 1920x1080px) and frame rate remains at 25 frames per second

Segment 2: 17:17 – 18:39 Local Time
Dimensions of the frame are reduced to 960x576px and frame rate is reduced to 10 fps.
It is in this segment that the position of the stirrer needs to be analyzed, yet it is blurred by Christopher Hariman Rianto.

Analysis of the Impact of Both Reducing Frame Dimension and Frame Rate on Mirna Salihin’s Hand
Reducing the frame dimension and frame rate can significantly affect the determination of whether Mirna's hand took the stirrer from the table or immediately stirred with the stirrer already in the coffee glass:
1. Loss of Visual Clarity: The reduction in frame dimension diminishes the visual clarity of the footage, making it difficult to discern fine details such as the precise movement of Mirna's hand and the stirrer. This loss of clarity can obscure critical visual cues needed to determine the sequence of events accurately, leading to ambiguity in interpreting Mirna's actions.

2. Decreased Resolution: With the decrease in resolution resulting from the reduced frame dimension, important details such as the position of the stirrer and the actions of Mirna's hand may become less distinct or identifiable. Fine details crucial for determining whether Mirna took the stirrer from the table or stirred directly with it already in the coffee glass may be lost, compromising the reliability of the analysis.

3. Distortion of Motion: The reduction in frame rate affects the smoothness and fluidity of motion in the footage, potentially distorting the timing and sequence of Mirna's actions. Rapid movements, such as reaching for the stirrer or stirring the coffee, may appear jerky or disjointed, making it challenging to accurately assess the sequence of events leading up to Mirna's actions.

4. Loss of Temporal Detail: The combination of reduced frame dimension and frame rate results in a loss of temporal detail within the video, making it difficult to reconstruct the timeline of events accurately. Subtle movements or changes in the environment crucial for determining whether Mirna took the stirrer from the table or stirred directly with it may not be adequately captured or represented, leading to uncertainty in the interpretation of Mirna's actions.

Overall, the manipulation of frame dimension and frame rate complicates the determination of whether Mirna took the stirrer from the table or stirred directly with it already in the coffee glass. It underscores the importance of conducting thorough and meticulous analysis to mitigate the impact of such alterations on the interpretation of events depicted in the footage
