it's a hard decision for me in this times to understand wich camera to buy, because I'm not rich at the moment, and I wish to have the best, then the market is going to change (maybe we will se the 4K home cinema for the new upcoming playstation the 20 of feb 2013, stay tuned), maybe the next-next Iphone also will be able to shoot at 4k also very soon, who know? well, I'm living now and I have to do my decision with what I can afford now. I know very well how the canon dslr works because I have read many reviewes and forums in those years. the problem is that, except 5DMIII al the canon-s have moire and aliasing (I do not know why). I wish to know: how much moire is a problem for narrative and documentary directors? ...and, would be a different (better) look if you could shoot without aliasin? now on the canons you must turn low the sharpening in the menù to shoot, and I do not like that effect. do exist camera dslr (or different system) that allow the people to shoot without aliasing and without moire? thx for reading, Dan
DSLRs have moire and alias issues as they have high resolution chips designed for stills. In video mode they use line skipping to down scale the image to HD resolution. Dedicated HD video cameras use HD resolution chips that are designed for video. So they don't have to do line skipping and so you have less moire and aliasing issues (tho not completely free of them) In today's market I would not buy a DSLR for video work. The C100 is a much better option. Has proper sound, built in ND and many features designed for video work. Along with a much better image than a DSLR. Can produce.
thx this would be awesome but it's more than 5000 euros, I have a little more than 1/5 of that price as budget. also I belive that from the 20 of feb 2013 we will see news like "4k for the home cinema" evrywere. I belive that monitor pc and tv will be developed now for 4k, and maybe a lot of dslr, cam coders will come with a 4k native support. ....the 20 of feb sony will show the playstation 4, I know that sound strange (maybe some one can say it's only a videogame). but playstation as I know have been the device who bring the 1080p on the home cinema, after that many followers came out with specific devices (other brands). new standard tv evolves thx to the blu-ray made by sony..... also many cellphones now have a 1080p camera. so I belive that spending all those money now (more than 5000) for a 1080p device -could be- not a good idea because -maybe- we are going to see a revolution in the tecnology sector. now we see Philip Bloom that use a Canon 4k that cost more than 10'000 euros, when maybe in 4 years we will have 4k on the XXD serie (if not canon someone will come for first I hope). So I really wish to spend my money for something wich can archive the video quality wich I like (that must be sharpen and clear), under 1000 euros and if possible less! eheheh! thx for your help! p.s. for me is very important to understand how much moire is a problem for narrative and documentary directors. because if it is not a problem for the professional use, I will buy a dslr used with a good lens, but my intent is the professional use so the question about moire and sharpening is very important for me, Dan
Yes it absolutely is a problem. It's distracting, cheapens the image to the end user (even if they're unaware of it), and it's 'The Mark Of Cain' in that your buyers might try to beat you down on price claiming it was filmed 'on the cheap'. Sony were so paranoid about their cameras exhibiting aliasing and moire, they lowered the final resolution. You can add it back in at the edit stage, where it can be done better because it doesn't have to be done in real time. This is how it should be. Many people talk of switching off in-camera sharpening, but they don't talk of adding it back in post. I'm an editor first, so am particularlly in favour of this process. However, news/ENG footage often has no time for post production magic which is why many cameras use Picture Profiles to deliver a station's look direct from the rushes. The Panasonic GH2 (and the GH3 if some reports are to be accepted) do a good job of this, but you have to work harder with exposure and camerawork. It's not totally absent, but it's darned good. Better than it should be at that price point. There are plenty of cameras that don't exhibit visible moire and aliasing, but they cost many times more than your current budget.
I will try my best to archive my goals really thanks a lot for talking about this. I really appreciate the post processing techniques could you explain how do you archive this goal please? do you use premiere maybe (because I have only it unfortunately)? about moire have you aver tryed those filters? if yes do you belive are they practice for the use or are them uncomfortable for the professional use? (they are aviable also for XXXD and XXD maybe I can get a 550d used plus this filter I do not know if it would be a nice goal) http://philipbloom.net/2011/09/13/moire-2/ I mean, I have to shoot a film scene, I have actors it's all ready, I can't fail, or I'm shooting an interview for a documentary, I can't fail, ....are those filter a possible obstacle for possible accidents? thx I saw the prices and they are ok for me thanks for advice Matt. I think this could be a way I will evaluate this in the depth reading the panasonic threads searching for good lens and prices and checking the total, thank you and have a good evening! Dan p.s. for you
I didn't know Mosaic Engineering had made a screen for the 550D - thanks for the info! If you watch the video by Glenn Przyborski There's a spot where he shows 'Final Cut Pro 20% sharpening'. That's the 'dirty little secret' for those of us who can't quite live without pictures with a little 'bite' (sorry, Philip). Essentially, you shoot with sharpening turned off or way down, then in post use a sharpening filter at a subtle setting (starting at, say, 10% - 15% on the FCP7 filter - and if you have two in the list, it's the second one) and the default for FCPX at 2.5 is just about right for corporate work - maybe slightly less for narrative. There's a plug-in called Tonalizer that does a very nice sharpen, subtle but effective, but it's computationally and fiscally expensive. Maybe this blog post may have some helpful info in it...
hello Matt, sorry for late I was a little bit taken by many thinks! Thanks for your advice and your kindness, I'll try this technique! About the "question of moire" I belive I'm going to buy the filter for the 600D if I will find a used body in my town! I saw that the Nikon 5200 does not suffer from moire and aliasing problems, so I'll take a look on the forum before buying the 600D. p.s. ....about the PS4 and the phantomatic 4K videos for the home cinema it have not been revealed yet. we should wait for the E3 exhibition in Los Angeles, when Sony will show the full aspects of the PS4 (util now they have not shown the console yet, but only some future games and the gamepad). See you and thx again for your help! Dan
