Cache vs. SD card file size and quality

[Bikedrone]

Hi all, with regard to my Mavic 2 Zoom, can anyone tell me if the original video stored on the SD card is the same file size and quality as what's sent by the DJI app and saved to Cache on the iPhone or iPad mini.

The video on the SD card is much higher quality because it's recorded directly from the camera, not compressed on the fly and transmitted by radio.

I don’t have the mavic 2, but for the p4p the resolution of the cached video is 720p even if your recording 4K. And the cached video will also have any transmission quality issue as well. The video on the SD card is of much higher resolution and image quality.

Not sure the right forum for this, but given the topic...is it possible to up-convert that cached info to better format? I lost my SD card and I just "found" the video's pics in the Go4 app under editor. RN it's 1920x1080 and .264 and in MP4. Expectation is low so any info would be helpful. Using APP-CC 2019. TYIA
