Data, are you saying that 960x540 is "better" than 1288x388 for anamorphic shooting with the T2i? If it is not too much to ask, how do you calculate pixels? Thanks.

Hey, so looking at the google Doc and my own tests I learned something:
By setting the resolution to 720P 60FPS, and using the FPS Override to 23.976 we can shoot at a whopping 1280X388 (2.35:1) on the 550D instead of the 'official' 960X540
holy. shit.
It seems that you need to 'warm up' the card a bit to do this, but I will do some more tests and get some sample footage out for you all by monday(ish) MAYBE tomorrow.

If you are recording and run out of space on the card, when you try to extract the dng files you'll get the following error:
Error: This ain't a lv_rec RAW file
You need to replace the file footer information to get this back.
Here's what I did, and I'm sure there are easier ways, but this is free.
Step 1:
Download the freeware Hex editor from here:
http://mh-nexus.de/en/downloads.php?product=HxD
Step 2: Open the .raw file in the hex editor. Scroll all the way to the bottom.
You have 2 choices at this point:
Option 1 - Record another file with the same settings on the card, and retrieve the footer information in the hex editor. It should be the last 12 lines of the file. The downside to doing it this way is it'll only extract the same number of DNG files that the secondary file has listed; i.e. if your 2nd file is 200 megs or so, if you copy that file's footer information to the (assuming) larger troubled file, you'll only be able to pull out the first 50 or so dng files.
So I suggest you do #2:
Option 2 - Copy and paste this into your file footer:
52 41 57 4D 80 07 38 04 00 5F 37 00 F4 21 00 00 01 00 00 00 A8 5D 00 00 18 02 98 19 18 02 98 19 01 00 00 00 00 20 15 0B 26 05 00 00 20 08 00 00 38 0E 00 00 50 34 49 00 0E 00 00 00 0C 08 00 00 98 3A 00 00 00 00 00 00 00 00 00 00 88 07 00 00 08 05 00 00 1E 00 00 00 92 00 00 00 26 05 00 00 1A 08 00 00 00 00 00 00 00 00 00 00 00 01 01 02 01 00 00 00 42 1A 00 00 10 27 00 00 85 FD FF FF 10 27 00 00 3D FC FF FF 10 27 00 00 41 EF FF FF 10 27 00 00 AC 30 00 00 10 27 00 00 EC 07 00 00 10 27 00 00 74 FC FF FF 10 27 00 00 72 08 00 00 10 27 00 00 24 16 00 00 10 27 00 00 82 03 00 00
Save the file, and start unpacking your dng's!
This will work for file sizes up to 32gb.
**Of note - say your "bad" file was smaller than 32GB - let's say it was 11GB - by using this footer it will try to unpack 8692 DNG files. Since I'm not smart enough to read hex, I just estimate where the good dng files should be and delete everything after it.
Here's a screen shot of the pasted in footer:

Tiff sequences might be a little large. Definitely use DNxHD 10bit. DNxHD does not come with Adobe After Effects, it's a free Avid Codec.
Download codecs for Mac here: http://resources.avid.com/SupportFiles/attach/Mac_AvidCodecsLE_2.1.zip
Download codecs for PC here: http://resources.avid.com/SupportFiles/attach/PC_AvidCodecsLE_2.1.zip
To use it, in AE render settings, choose Quicktime and click on Format Options, choose DNxHD, click on Codec Settings and choose 1080p 444 10Bit.
DNxHD is a fantastic codec - but it only allows up to 1080p recording. Nothing higher in resolution unfortunately.
Cineform is just as good with more options. Just make sure you use the 4.2.2. Full HD option (and if you have the premium version, use the 4.4.4. option).
Now remember, when you are finished grading, you can render a version for the web using the H.624 to make uploading quicker, but you should always keep your final DNxHD, Cineform, or ProRes renders for archivals.
Yep. Tiffs are big. The "20 Bucks" Raw files were converted into Tiffs, 180gb and DNG's, 56gb. To save space I deleted the Tiffs and saved the original Raw files and the DNG files, 112gb total. Cool! I got the Avid codecs installed so rendering DN x HD is the way to go. DL this is so cool. Thanks!

So basically a 550D's max MB/s is around 20? So it can't be pushed higher than those resolutions, unless you go for a lower fps? And glad you liked my music video, thanks!
Thank you so much for your kind comments! You think I should shoot my music video using my 550D in RAW? Or stick to what I know won't cause problems (ie: normal h.264 shooting)? It's difficult. I think I need to get more used to shooting RAW. I went out yesterday and filmed some stuff in RAW and I'm using GingerHDR now to edit it through Premiere. Is this the best method? The workflows I've seen are what I'm dreading the most... GingerHDR seems to have given us the simplest way to edit RAW.

Thanks!
I do not convert to CinemaDNG because Resolve doesn't seem to use all the information available.
Here is my two different workflows. Ill be doing a workflow tutorial soon.
1# Without using the Flatz Preset
1. Export RAW to DNG frames
2. Import DNG frames to AE
3. Export HD H.264 Proxies
4. Edit in Premiere
5. Copy edit, Paste in Adobe After Effects
6. Replace HD Proxies with DNG frames, Color Correct in ACR
7. Render in DNxHD. Add back into Premiere for sound and final render.
#2 Using the Flatz Preset
1. Export RAW to DNG frames
2. Import DNG frames to AE, apply Flatz Preset (adjust white balance/tone as necessary)
3. Export 4.4.4. DNxHD files
4. Edit in Premiere & Render
5. Color Correct in Resolve & Render.
Hope that helps. Ill be posting my workflow video by Wednesday at the latest.

Hey folks! I just wanted to share a free Adobe Camera RAW preset that I believe will be very useful for others as it has been for me in post processing.
This plugin will take your footage and flatten your image so you can render into Pro-Res, DNxHD, or Cineform and color-grade in whatever program you wish.
Give it a try and let me know what you think!

Anamorphic means no-morphic, so not keeping the original shape. Only one dimension is squeezed, normally horizontal one. So height is not at all affected. This is the beauty and the main characteristic of anamorphic lens.
Quote from: pooli on August 02, 2013, 12:47:42 AM
If you anamorphic factor of 1,33х you can get a 2.35:1 video . For example, if you have a height of 960, then it turns out to 2.35 x 960 = 2256 your frame width. I hope I understand you correctly.

Hi guys. My test
I used MEOPTA ANAGON 2X Projection Anamorphic attachment with lens helios 44m on my canon550d
SD card
resolution - 960x540
aspect ratio 16:9
24 fps
1920x540 (3,55:1) on post
Pooli you seem to understand anamorphic ratios. Help me out. I am shooting with the T2I 960x540 and 16x9 with a Panasonic LA 7200, that has a 1.33 squeeze factor. If I want the image width to be 1280 or 1920 what size should the height be with the 1.33 squeeze? I'm using CS6 and Resolve. How do I unsqueeze the image in those programs?
In your footage the vertical number 540 did not change but the width did? Maybe, I think I might have something, the squeeze is width only? Then, how do you calculate 3.55:1 x 960 to get 1920? How would I calculate 1.33 x 960 to get 1280 or 1920? I hope my questions are clear.
All is well,
Derrick
