I'm curious about something......have you done a comparison with a photo taken and one captured from the video?
Good Question John....
In the set above, the 1st was a direct capture... the others were extracted...
Viewing all in lightroom, no real discernible difference.... the resolution is higher in the direct image:
Direct ----------------------------------- 3992x2242
Extract from 1080 Processed -------- 1920x1080 (that is what the extractions above are)
Extraction from un-processed vid --- 2701x1520
John, have not done any real pixel peeping as that is not my style but I have been pleased with the images in all 3 resolutions for my purposes (scenic). I would not crop or blow up anymore than I would not crop or enlarge any further than you would any other 12 megpxl or 8 megpxl image.
No Real difference for normal purposes of scenic aerial stills..... Hope this helps a bit and thank you for reviewing and asking questions.
