Looking at my earlier Topic about the Sony CX405 and its version of XAVC-S files, I think this is the topic I should have started in its place. I do not expect to post much. The only post I have in mind for this topic is this video. Ironically, I have already posted material and information in the earlier topic that should have gone here. If I find other things to add later, then this is where I will accumulate them. I prepared this video with this topic in mind. I recorded the camera files on my Sony HDR-CX240B in AVCHD in 1080i format. According to the information I got (I believe from Sony) the camera renders frames at 29.95 fps and then stores them in two fields, each having half the screen data. The camcorder also supports 1080p. The main reason I do not use 1080p is that it uses more storage and I have never felt that the extra smoothness added significantly to the viewing experience. In the case of low light video, there is an added theoretical advantage that the longer time between frames can be used for longer exposures for even lower light, but if things are moving, and in a video, you expect things to be moving, that would result in blurring, so I do not count that as a substantial advantage. As far as I know, if I use the AVCHD settings in the later CX-405, then there is effectively no difference between the output of that camera and this older CX240B. All exposure is manual. Theatrical lighting is highly unpredictable, but in general, you can count on an experienced professional lighting team to keep it even enough overall. The first part of this video (the "Yate Dance and Acrobatic company" -- the girls in the green dresses) was under exposed probably about 1 stop. The only "adjustment" I made in the whole video was to lighten this part. Looking at the results, I think I lightened it a bit too much compared to the aerial and skating parts, but on its own it is acceptable. Aside from the brightness though, on close examination, noise will probably show up more in this section, and should not be held against the camera. The skating and aerial acrobatics are all a single file. After finishing the first song, the second song began with only the very short break that is in the video. The camcorder had done a very good job. It rarely lost focus and then, only briefly. The decreasing aperture when the zoom is farther out has not resulted in substantial noise. With proper exposure the colours generally turned out well. Because YouTube does not allow higher bitrates than you see in this clip, effectively a camcorder or rig costing thousands of dollars more will probably not do a significantly better job. As I noted above, I put this video together specifically to show the output of the Camcorder. This is not my normal output style. Especially for skating, and really in most of my videos, I use stabilization in post. Mostly I record with the camcorder on a monopod and with the camcorder's built in stabilization On. So in effect it is "triple stabilized". The last stabilization in post, however, does smooth out errors caused by the camcorder's stabilization. Sometimes when you pan the camcorder holds the image still until it reaches a limit and then it jumps. In post, most programs will find those jumps and smooth them out. Sometimes I get caught with the zoom wrong and I need make a quick change in the focal length. Editing programs will often smooth out those zoom errors as well. However, stabilization in post always looses some quality. How much will depend largely on how much correction is done. But you can expect the result to be somewhat less sharp and less detailed. So this is one of the few times I have posted a video that can be used to show the capability of the camcorder (subject to YouTube recoding) fairly directly.

The first part is a substantially different presentation many respects so they are never really going to match, but this version comes much closer. If you saw the first version, there is not that helpful to see the second.
