It's a Transcend 32g 400x. Looks like it's a slow card? If so, which should I buy?

I used to record continuous 720p on such card. Build 28 May, GD on, histogram and scopes ON, but zebra stops recording, so was OFF.

In the latest build of 25 June after I have set ISO and trying to adjust exposure, changing aperture is fine but attempt to modify the shutter speed modifies ISO for some reason.... But the main drawback of this build is 2-3 seconds sequence and then skipped frame. While 28 May  build works fine continuously. With all GD settings the same.

Which ones? I'm not aware of any...

I woudtn't advice you to use the latest releases for non-test purposes. Besides short sequences, they have other malfunctions. That's why I still use 28May build )

I got it installed on my 50D. Any ideas why recordings stops after few seconds? I even chose a smaller resolution like 1280x720, it still stops. Is there a setting that I forgot to turn off/on?

All I did was extract the file magiclantern-2013Jun25.50D.109.go.unified.282abfa87fef.zip onto my compact flash. I'm not sure if there are other files that I need to download.

hmmm......okay.

but do you also have the problem of flickering images in resolve? every now and then theres a heavily darker image.
and there´s some blue and red noise at the image borders.

crash, I used to have the same issue with Resolve (flicker + glitches at the upper border). Replaced my Resolve with the latest Lite version from BMD site -- the issues are gone.

Are your 50D's heating up?

Mine goes 50-52C

I was testing Unified Build of 19 June.

I often increase contrast of images to see some textures/bugs that are not obvious but could pop up in post.

That's the texture that I saw:

100% crop



And also with x5 zoom:

100% crop



I was doing stable shooting @1600 at Transcend x600 card.

use 1%'s and turn on "Don't click me!"

which one is that? thanks

[turn on]

Just got my new Transcend x600 32Gb. OMG, it works!  (tears of joy))

Some strange behavior: when I shut GD off and shoot continuously @1592x896, the buffer gradually fills up at approx 40 sec and the shooting stops.
But when I turn on Global Drawing the shooting goes smoothly with 1-starred buffer.
I'm using 28 May build (being somewhat conservative at the beginning of the test). Anybody had this?

And yes, it's a battery eater. I have 2 used batteries that last through a loooong photo shooting. But RAW recording does them in 15 min, I guess. Additional batteries and AC adapter are being launched from China )))

EDIT: The following extra-battery discussion has overwhelmed my question, I guess )

Hey all,
Does anyone know if there is any good progress with truncating 14 bits to 12 bits? Together with the new writing speeds 12 bits would rock )

Andy, using your Transcend x600 card what max resolution you can run steadily @25p? My card is on the way, I'd like to know what to realistically expect ) thank you man

My first real test oudoor with my new 50D.
Shot at 1584x892, graded in AE with ACR, scaled up to 1920; scaled down to 1280 because vimeo won't let me upload a file bigger than 5gb.

Used the cheap Canon 50mm 1.8f; looking at the footage, makes me realize the importance of image stabilization, which this lens obviously doesn't have.

Yep, I almost got seasick by the end 

...

FYI I get 1584x892 (16:9) continuous and 1584x950 (5:3) for a couple of mins at 25p with write speeds up to 65MB/s. (yes 25p )

That settles then. THNX!!

Hi Andy.
So Transcend x600 will allow full 50D Resolution for, let's say 1 min non-stop for sure? I'm also looking into buying one.
Thanks for your info!

If you're looking to buy it I suggest getting the Transcend 600x 16,32 or 64gb which is cheaper and works. I have the 16gb and 1584x950 is no problem. Writes up to 65MB/s.

Alternatively get the Komputerbay 64gb card which is good value for money, even though mine was DOA. Ordered another.

I know we've all gotten used to it by now but, I'm madly in love w/ the 50D's new-found digital cinema capabilities thanks to you guys here.
I alternately swap between RAWanizer DNxHD export and Lightroom export depending on how much latitude I want. Here's one workflow I've used for the commercial spot we're shooting:

1. DNG to Lightroom (specifically to save latitude)
2. export upscale to 1920px horizontally at 100% JPEG quality
3. edit in Premiere CS6 (JPG frame sequence)
4. export as DPX LOG frame
5. color in AE CS6 (combination of adding a specific LUT base, then grading in curves, sharpening and adding 35mm grain scan)

Man, you do color corr to 8-bit picture. Why bother with RAW then? )

A quick test, worst case scenario for me, high DR and very fine detail and shot with a pretty bad 28-70 canon 3.5-4.5 at f9 (waiting for nikkon adapter). I got a lot of aliasing. I made some slides which turned out to be horrible but at least you can see the movement which induces aliasing.
1592x636 1:1 mode, build May 28th. Had to shoot in this low resolution as I'm still stuck with some old 4gb 32mb/s card.

Workflow. raw2dng->AfterEffects->h264 (I tried to compile the compositions and use them in PremierePro but I was getting strange speed jumps)

I fixed the alisasing with defringe option in ACR and sometimes with NR ,color 100, colordetail 0, although you have to be careful not to kill your colors.
...vimeo....

wow, this is AMAZING! thanks for showing this. I hope I will overcome my moire problems )

The issue can't be fixed once the aliasing got in the digital domain; you just can't fix it in post. Well, maybe if you are Ken Rockwell so you can break some physics laws...

You can also record slightly out of focus. This will work.

Read some signal processing theory before blaming ML or conversion tools or whatever other software things.

Thanks for a nice answer )

What version of Raw2DNG are you using?

I'm looking into properties of .exe file and there is no info on version. Where can I look up it?

...

One thing I do for sure is disabling sharpening when converting the dngs. I do add it but only after resizing to my desired resolution.

Julian, how do I do that? thanks

I'm not sure how your getting all that Moire must be a setting, or setting maybe the way your converting your Raw to DNG.  My 50D has little to none moire & aliasing, don't get me wrong it's present but not like what I'm seeing here.  Let me know your conversion process after shooting.

I do hope there something in the conversion, or else my investment is futile.

I did Raw2DNG -> Import to AE CS5.5 -> Save Frame

As per questions to my frames:

- I have not applied sharpness
- I shot with the max resolution for 50D - that was the main idea behind loaning a fast card
- one frame is 100% crop and the other is enlarged to 1920x1080

Hello people,

A couple of days I made a decision to go for 50D. Couldn't resist this RAW monster

I loaned a fast x1000 card and did my first test shoot.

But I was surprised (in a bad way) with moire. Is it something to leave with? Or can you suggest any solution?

Thanks!

Hey all.

I'm a fan of ML, have used it on my 550D a lot and now am very close to decide to buy a used 50D -- all for the sake of RAW video. I also took part in 1% cam donation -- this is my token contribution to all the HUGE work that's being done here.

I have 2 questions though that bother me:

1. I see all these amazing test videos with 24 FPS. Is there 25FPS? For my work it is crucial.

2. I read the other day about the problem with electronic aperture for EF lens. I would appreciate if someone assures me that I can control my electronic aperture while shooting RAW video.

Thanks a lot people! This community is cool 

I'm in for $10 for 1% too
