50D Raw video

[nightvision04]

Nice video. Which cf card are you using?

Thanks to everyone involved on this project. Your work is greatly appreciated.

I'm no expert, but if the 50D is able to record 1584x892 continously at full sensor (or even 1584x1058?), shouldn't we be able to record at higher resolutions with cinemascope ratio? With 1584x1058, let's cut 200 pixels from the height and extend the width - that's almost FullHD at cinemascope.

You know, I'm sure a lot of people thought about this. So I bet it just doesn't work (yet). But I'm curious; why doesn't it work?

Why doesn't what work, you can record the whole non zoomed LV for a while.

But I'm curious; why doesn't it work?

Because the camera isn't reading the full sensor resolution (4752 X 3168) and scaling it down to what ever we want. It skips every third line and column to reduce the resolution to 1584 X 1056. In crop mode, there's no skipping so it is possible to get higher resolutions.
If the developers would find a way to set the skipping from 3 to 2 it would be possible to record higher resolutions on the 50D, even without the strong crop. And it might reduce the aliasing. But that would be too nice ...

[niggo]

@1%: The question is "Why can't we record continously at higher resolutions?" - and I'm not talking about crop mode. I'm mostly interested in shooting cinemascope, so all those extra pixels in height don't interest me. I'd much rather like to add those to the width.

@CFP: I see, so 1584x1056 isn't a limit in regards of write speed but rather the line skipping?

[1%]

That is the image size without zoom. You can take the whole thing or 1584 x whatever.

Also taking out the skipping will probably increase the crop. It seems that way on every canon. Resizing the raw buffer, if ever possible,  will probably lower FPS.. which might be OK on 50D since its 30fps all the time.

[CFP]

Also taking out the skipping will probably increase the crop.

But if it would be possible to set the skipping from 3 to 2 the image's size would be 2376 X 1584 right? If you choose an aspect ratio like 2.5:1 you would get a resolution of  2376 X 950 (Or 2368 X 960 with multiples of 64) which would require 90 Megabyte/s. It wouldn't increase the crop and should work for a few seconds. Setting the aspect ratio to 3:1 or decreasing the resolution slightly would make it continously.

But that's just one of these pointless "if & would" ideas. I'm not expecting to see that possiblity soon. If it exists.

@CFP: I see, so 1584x1056 isn't a limit in regards of write speed but rather the line skipping?

As far as I know: yes.

Okay guys, so an update.

I just wrapped a commercial shoot w/ the 60D but used the 50D ML RAW for a few interviews. They're brief cuts, but the results were amazing.

As a result, I've purchased a Transcend 128GB 1000x card for full production purposes and wrapped principal for a fashion film short. The results are f'ing STUNNING. This time around I used a Davinci Resolve process to DNxHD 10bit 422>Premiere CS6 edit>LOG DPX esport>AE CS6 color (yes, Resolve would be just as good, but I'm accustomed to the AE workflow right now).

Hi guys,

here´s my comparison between ACR and Resolve.
Natural grade in ACR and extrem greenish day for night something in resolve...

Great shots! What lenses did you use? Also did you shoot in crop mode? I can't see any strong aliasing there...

[funkysensation]

for wide shot´s i used a tokina 12-24mm and for the closer ones sigma 28-300mm no crop mode at all

Hi
It is possible to get the same result in terms of cc with resolve comparing to ACR?

One of the best so far.I like the spec. 160Mb/s. Nice,on my wish list.

[mjstudio]

nice grade,

lads, how do I change resolution ?
 I press Q just like with 5mdII and it just jumps between 1920x1080 an 640x480,  (9th June build)

You have to load the raw modules first, go to "M" menu on ML menu.

Thanks for a quick reply.

I did, just didn't find the separate raw recording field, in the scroll down menu. Found it eventually

Another thing. I have 600x udma6 32GB Kingston card and it won't let me go over 40 frames at 1584x892, any ideas?

[v1rt]

Hey guys,

When I go inside Resolution and move my selection over 1600 menu or any resolution above 1600, the status says

1600 is not possible in current video mode (max 1584).

I was told that our 50D can do 1920 raw.

Thanks!

You'll have to press the 5x zoom button on your 50d. The recording resolution will automatically change to 1920x1072.

[mjstudio]

now 50d is so much fun!
Thank you guys!

You'll have to press the 5x zoom button on your 50d. The recording resolution will automatically change to 1920x1072.

I tried it but it didn't work. It still picked 1584x892. Maybe because my cf card is slow. Do you think it's because of my non-1000x cf card?

[1%]

You have to change resolution in the raw module when zoomed in.

Got it to work! However, what will be recorded as video? Is it still going to record the non-zoomed area? Btw, it stopped after 2 seconds. My 400x is so slow, LOL Really need to buy the 1000x cf cards.

That's odd. So you're saying that while you are in 5x zoom mode, if you enter the magic lantern menu, you don't see a grayed-out "1920x1072"? I'm probably stating the obvious here... but the 5x button isn't an on/off switch 1920 recording, it's a different video mode altogether.

The card you are using exceeds the bitrate required for 1920 recording. Perhaps 1% can comment?

[Andy600]

Just tried 1472x828 , 40 frames and stops 

The Kingston ultimate 600x is not actually UDMA6. It's UDMA6 compatible. The write specs are way over rated. I have one and it's crap.
