The correct answer is A: Constant Rate Factor (CRF).<br /><br />In this scenario, where preserving every detail of the footage for future editing is crucial and file size is not a concern, Gustavo should choose the Constant Rate Factor (CRF) data rate control mode.<br /><br />CRF is a mode that allows for variable file size while maintaining a consistent level of video quality. It adjusts the bitrate dynamically based on the complexity of the video content, ensuring that the most important details are preserved while maintaining high quality. This makes CRF an ideal choice for situations where maintaining the highest possible quality is a priority, as it allows for more efficient use of the available storage space while still preserving the details of the footage for future editing.<br /><br />In contrast, Lossless (B) would result in the largest file size without any compression, which is not necessary in this case. Variable bitrate (VBR) (C) can also lead to variable quality, which may not be suitable for preserving every detail. Constant bitrate (CBR) (D) maintains a fixed bitrate, which may not be efficient for preserving every detail of the footage.
