The full video sequence was discovered by @Astro_Aure@twitter.com on the ISRO website: https://www.isro.gov.in/media_isro/video/Home_video/Ch3_lander_descent_rover_rollout.webm
You can see the original frame blending interpolation in that video.
Unfortunately @isro doesn't provide a high quality version of the images...
To find the original unblended frames my python script uses a high-pass filter to look for edges in the frame. Basically, the fewer edges it finds, the more likely it is to be an unblended frame.
