Title: Questions and need advice...
Post by: emphram on January 27, 2015, 07:37:27 AM
So I've been fooling around with my 600D and RAW video and found interesting results. While I'm getting a whole lot more detail, I'm also getting a whole lot more noise (I'm using auto ettr but I only have a kit lens and have only been able to shoot in poor low light condtions, will try shooting in daylight to see if the problem is strictly related to low light).

As a windows user, I'm pretty confused as to how the workflow goes with this type of footage. I tried MLRawViewer, but sometimes it would corrupt my video when using sRGB curve. I keep reading about different workflows but I still not sure which one to use. I want to end up with ProRes clips that are upscaled to 1080p and just use those in premiere (anyone got any workflows that can work like this on windows?)

Another issue, some clips will have what appears to be major chromatic aberration in a very strong magenta color. Or sometimes there will be a random pixel or group of pixels that is 100% magenta in the middle of nowhere. How does one fix or prevent this?

I'm considering purchasing a better camera, but I can't decide between the 700D, 6D or 5D2. I have a limited budget, and any of those do higher res raw than my 600D, but I don't know which of the 3 is the best investment.

Regarding the previous, the 5D2 does not have exfat according to the chart in the ML cameras raw res, does that mean every 4gb the shot is broken up into another file (loosing frames in the process)?

Any tutorials on how to use Auto ETTER properly, I haven't found one that I completely understand yet.

Thats all for now, but I might have more questions. Sorry for being redundant and asking what is probably old and boring questions, but I just don't know where to start when it comes to RAW.

EDIT:
I just saw that there is a childboard for workflow, and I was able to find post process tutorials that made much more sense than the bits and pieces I picked up from random threads, that helps alot, no need to answer post process questions now. My main question is however which of the 3 mentioned cameras  would be better for continuous 24p or 30p raw shooting? I'm inclined to go with the 700D because of price and if 960*518 impresses me, I think 1280*720 raw will do so even more. Also, it means I wouldn't have to buy any new batteries and my SD cards would work on it.

Hi, I'm trying to help you as I have the same camera. I shoot in 1728x516 MLV and convert it with mlvsharpviewer to a .raw and then with raw2dng.exe to dngs. Those all have strange pixels and green/sometimes magenta areas, but when I import them into Lightroom , everything is gone and I have a very crisp image which uprezzes nice to fullhd or even 2k. I would recommend a 7d (around 800-900€) or a 50d (have seen it for 300€ +70-300mm). Both use cf cards, and if I had the money I already had one. And here, in case that you didn't already see it :     https://docs.google.com/spreadsheet/lv?key=0AgQ2MOkAZTFHdFFIcFp1d0R5TzVPTVJXOEVyUndteGc&f=true&noheader=true&gid=0

As a 5D2 User on ML Raw for the last Year, I would say Its the Most Stable of all the Camera's with rock solid Audio & HDMI Support (EVF or hdmi recorder etc..)
At 1872x936 24p or 2048x872 in 3x crop MLV+Audio continuous  , I have seen this camera used starting @ $750.0 to 800.0 USD on Ebay .
Of all the Camera you are looking at I would suggest (being a little bias) :D Is the 5D2  and it's in the price range. Yes the 5d2 is Fat32 , but with spanning files
you don't miss a frame, I have filmed up to 10 minute in one take on a 64 GB 1000x CF with out any problems (I do news/docs., music video stuff).
If you Use Raw version 1.0 you will have more frame resolution to choice from if you don't need audio. Max continuous resolution is 1880x1016 @24p 1:1
and 1920x1038 ,2048x930 in 3x crop mode. Link to a post I wrote on resolution -->http://magiclantern.fm/forum/index.php?topic=11205.msg136460#msg136460
