I think that it might be writing faster from the master CPU saving the penalty of overhead from communicating between the CPU?

Well I'm planning on trying to boot on the master... thought the edmac and card controller is separate from the digic I think... the master might have less CPU usage tho. Guess we'll see.

Can't wait to be able to play back MLV files in the camera ....if that's possible :)
Love my EOS7D!

You can already do this. To some extent.

I decided to pull the trigger on the Mk3 and was really surprised to only get 51 frames in crop 2560x1164 (without FPS override) , the 7D can get almost double that in 2512x1200 , (buffer size ?)

Fortunately the continuous 1080p with no aliasing and moire in non crop is just amazing , i just expected it to perform decently in crop at higher resolutions

Highest i could do continuous was 2048x1152 24p in crop with FPS override (94.5 MB/s)

By the way has 1% received his 7D ?

Best

Almost, almost...   :D

Sometime i can shootting 2,5k with non crop mode. I don't know what that mean.

On 5D3 if you enable:
Preview: Hacked
Memory hack: ON
Small hack: ON

I get 126 frames on 5D3 on Lexar 1000X

On 7D I only get 95-110 on same card

i think,
the best would bi ,if Magic7d ships the camera to 1%,and once you colect the money for the cf card,to buy the card  on amazon.com and deliverit to 1% addres.

Picking up a Canon 7D today, chose it over the 50d and gh2.
Hopefully, it will stand next to the 5d mark II/III in terms of raw video.
fingers crossed.

Will donate happily to the cause.

I already grabbed it from ebay when the camera tracking moved so the price wouldn't go up and I would have at the same time. I'm betting everything gets here by friday. 7D is in country at least.

Hi, do you mind to tell me more? :) I'm fairly new at this and tried to search and read through the forum but couldn't find anything yet...

Thanks in advance.
Love my EOS7D!

I'm glad to hear it
I want to thank you for the help you give,and not least to thank Alex and g3gg0 for all the effort they have made
for us to have such a toy with which to play
I hope to hear only good things in the coming days
thanks

Trying to test the crop mode and see if I could push the resolution. There are still bad frames and not continuous.
I'm using Lexar Professional 1000x 32GB card.

What's with that flickering? I read that ACR caused it?


1st.
Canon Setting: 30fps
ML Mode: cropped
ML aspect ratio: 16:9
ML resolution: 2048x1152
Total Frames: 127

2nd.
Canon Setting: 30fps
ML Mode: cropped
ML aspect ratio: 2.35:1
ML resolution: 2048x872
Total Frames: 343

Love my EOS7D!

I'd love to clarify something real quick before I go down the road of buying a card and learning how to install ML on the 7d.  I've been gleaming from some previous posts that if you shoot at 720 resolution, you will increase the crop factor of your sensor because the camera will only record part of the sensor field.  Is there any way around this?  I don't see much use in shooting full 1080p resolution because the file sizes are too large and I want more than 13 minutes per 64gb of memory... but I also don't think a 3x crop factor would be workable for me.  Hopefully I'm missing something and this isn't the catch 22 I'm presenting here.

The 3X crop recording in raw video is indeed much sharper and less prone to aliasing and moire due to it recording 1:1 pixel from a cropped portion of the sensor, unlike 1X which employs line skipping to record from "almost" the entire height and width of the sensor.

This is different from 720 60P recording in h264 which is also recording from "almost" the entire height and width of the sensor but at more lower res to give you downscaled 720 60P and more aliasing and moire than what you see in 1080.

64gig gives you approx 15 min in 1728 x 972 resolution @ 24P

On 7D Raw video at 1280x720 and 29.97 fps does not require any crop!  Only if want more than 1728x972 will you need to use crop.
On 7D Raw video at 1280x720 and 29.97 fps requires a recording speed of 46 MB/s.
On 7D Raw video at 1280x720 and 29.97 fps generates 2795 MB (2.8 GB) every 1 min, therefore 13 min = 2.8*13 = 36.4 GB

In 7D
technically, in Crop Mode its recording a "cropped" portion of the sensor.

However, in 1X, when you change resolution for example from 1728 width to 1280 you will see your framing guide white rec reduce in size poroprtionally thus recording only a "cropped" portion from that of 1728, so yeah, its still cropped with line skipping while 3X crop does not employ line skipping, thats the difference I guess.

Your terminology is correct but in RAW video I refer to "cropped video" as the video obtained by pressing the zoom button.

3 sep kl 04:22   Stockholm EMS, The item has been dispatched from PostenĀ“s international terminal for onward transport abroad.
3 sep kl 17:51   U.S.A., The item has arrived at the international terminal in the destination country for sorting.

Thanks to all that help/participated in this, you know who you are!!! And a special thanks to Magic 7D and 1%.

That the games begin  :D

Thanks for making that clear.  So I guess the catch 22 does exist for shooting RAW: either you shoot 1728 and have to buy a bunch of cards to handle the massive data rates, or you shoot 1280 and have to buy a bunch of wider lenses to compensate for the smaller image plane.  Does this happen with all the cameras?  Or is this just a 7d problem that might be fixed.

All... so you need like 10-11mm lenses, etc. Some have better or worse down scaling in "normal" mode. Zoom also needs FPS override or it won't work/ you get 30P.

Have you guys tested some of the wide zooms with the crop mode to see which performs best?
I know that Sigma 10-20 has very low distortion, but not as sharp as the Tokina 11-16, for example.

Thanks for the response.  I think I fully understand now :)  Good luck with the programming!
