Hi, I was just looking at sample videos from the FZ1000 and noticed a weird aliasing effect when viewing the videos in a small window (not full screen) in HD. Either it's me and I'm going crazy or you can see it too. This is a random sample video I found - watch in HD and look at the cables and especially the trees!: Or here - play in this window and change to HD or 4K: While it might be somewhat nonsensical to play a video in HD in a tiny window, the effect still struck me as pretty weird! I noticed because I changed the videos to HD before going full screen. Especially for the vimeo video, the effect is very visible and I imagine a lot of people don't go fullscreen on every single video they watch. I haven't tried for footage from other cameras and perhaps this is a well-known effect and I just haven't noticed so far?? I do know a little about aliasing/moire and how some cameras are worse than others. But this isn't to do with the camera, right (as the effect goes away when you adjust the size of the window). Is this to do with the compression? Cheers -
This is a frame taken by my Sony A7s with PP4 25p Full frame Take a look at the tie. The picture speaks for itself. I thought that the A7s didn't have aliasing and moire, at least not in FF 25p mode!

Is there a full frame DSLR out there, that has no or at least a usable amount of moiré and aliasing in video mode. I can't decide in between a Nikon D7100 and a D600 which I am currently testing. Wait, that's not entirely true, I have, kind of, decided already because I love the picture that the D600 renders with my old 1980’s - 90’s AF (no D no nothing) Nikkors, I love the minimal DOF, I love the latitude, I love the vignette that some of my lenses make on the D600 (the D7100 does none of that with my lenses). But the moiré and aliasing on D600 is in my opinion simply atrocious compared to the D7100, which has some but it’s bearable for me. The shadow noise banding on the D7100 on the other hand, even on low ISO settings, kept me awake working for some nights to try to soften this flaw in post, (and it didn’t really worked out BTW). So, my options I think are, if I want full frame (shallow DOF, lens compatibility etc.) and the least amount of moiré and aliasing: the D800 with the mosaic engineering thingy or a D5 Mark III with a lens adapter or what else? Suggestions? Anybody?

Mosaic engineering have released VAF-TXi anti-aliasing / anti-moiré filter for Canon T2i (550D), T3i (600D), & T4i (650D). Designed to cut down aliasing, moire and false detail, resulting in a much better picture. http://store.mosaicengineering.com/VAF-TXi-Moire-Aliasing-Filter_p_14.html you can see Andrew's example of the version for 5D here:http://www.eoshd.com/content/7120/canon-5d-mark-ii-mosaic-engineering-vaf-5d2-anti-aliasing-filter-review I have mine on the way, I'll let y'all know how it works ;) JG
