comment How does HDR movie work?
Since the predominant display medium today is an 8-bit JPEG displayed on an 8-bit monitor, squeezing all of the information of a 14-bit file with 10-12 stops of dynamic range into a JPEG file with about 7 stops of DR is a form of High Dynamic Range imaging.

High Dynamic Range Imaging (HDR imaging) is much broader than combining multiple images into a 32-bit floating point file. It is any photographic method that allows a scene with a higher dynamic range than the display medium to be rendered by squeezing that range into the display medium. In the 1850s it was what Gustave LeGray was doing by combining an image of a sky and another image of the beach to create seascapes. In the mid 20th century it was what Ansel Adams was doing with the zone system and dodging and burning

You could also do it with a single frame from a camera that converts the raw data from that single frame into two disparately processed frames, one darker and one lighter. There is as much information in a single 14-bit raw file as there is in a -3, 0, +3 series of JPEGs.

Because it doesn't really answer the crux of your question: it merely addresses one of your mistaken assumptions.

For DSLRs, when shooting video the mirror does not cycle between each frame, it stays up the entire time. In fact, the shutter does not cycle between each frame either: it stays open. The sensor is read out electronically at specified intervals.

comment Why does my Class 10 memory card run in to buffering problems?
Probably another 'Class 10' card that actually performs to 'Class 10' standards instead of a phony 'Class 10' card.

comment UHS1 vs. Class 10 sd card (Samsung dv100)
The ultimate question would be, "Where can I find a list that tells the maximum speed memory card of which my camera is capable of taking advantage?" Unfortunately, to the best of my knowledge, no such list exists. Rob Galbraith's list was once pretty good, but doesn't seem to have been updated in years. And trying to access some links to the site now can be problematic.

comment How to disable continuos autofocus during video shooting with Canon SX230 HS?
This question appears to be off-topic because it is about audio-video production.

comment Software to edit .mov files from a Canon 7D
For whatever reason, the focus is much better now also. Other than tying up my DSL for a number of hours, this does seem to work for the basic things I need. Since the DSL bottleneck is only in terms of upload speed, I can still use the internet while it is uploading, It just takes longer for my requests for pages to get through. Pages load down to me at close to regular speed.

A possible reason for the download issue. Shortly after I uploaded the clip, it was showing a status containing possible copyrighted material. The clip was from a piano recital, and the piece was properly identified as one written over 100 years ago and in the public domain. Apparently the student played it so well that it was identified as a recent recording covered by copyright. I disputed the status and now it is no longer showing as possible copyrighted content and I am able to download it.
