Comparison of the results of capturing images of the Moon using different formats

A Sony ZV-E10 Vlogging camera fitted with a 350mm Zoom lens was placed on an MSM Star Tracker mounted on a fixed tripod to capture 1 minute of 4K video of the 95% illuminated Moon. Immediately after taking the video some 18 x ARW images were taken at F6.3, 1/200" and ISO 100 in rapid succession using the cameras burst mode. This was followed by a further capture of 39 x ARW's taken at the same settings, but at a reduced exposure of 1/1000". The 4K video was processed in PIPP to produce a 1524 frame SER which was then passed to Autostakkert!4 to stack 75% of the frames, with the resultant Tiff file sent to Registax to wavelet process the image before final adjustments were made in Adobe Photoshop 2024. The separate exposure ARW's were also stacked and processed in the same way, and produced much better results than the minute of 4K video with ~1500 more frames. The stacked separate ARW exposures were then combined by blending them together in Photoshop to produce a combined image. The experiment proved that although the video was able to take over 1,500 separate images during the capture, the compression format of the camera resulted in an inferior result to the tiny amount of ARW images taken.
