OK, I made aditional read up. Up to 81°C by ML. It wan't go much higher (24°C amb. here) and I wan't go further too, since camera is 2 month old....

Original reply was updated with new numbers.

A warm welcome, robert0! ;-)

Hi, Congrats on the ML for the 70d been waiting for this a long time since i got mine, it works a treat. Ive been through the user guide as this is my first canon dslr so my first go at using magic lantern. How do you shoot raw video from the ML menu. Ive tried it all and im still recording H264.

robert0 · « **Reply #353 on:** February 12, 2015, 02:58:56 PM »

Thank you wlater_shulz, warm to the letter

Now maybe i will look like a nit-picker, but still: some apertures on ML overlay are slightly off:

Code: [Select]

first column is what shows LCD panel, and second ML overlay. These are just wrong values.
I tried this on Tamron AF 17-50 2.8 non VC and Canon 17-85 IS USM. Wrong values was same on both lenses.

And one question: what is -0.5° value on appended screenshot (top-left corner):

When I turn on camera, this value it's not there, just time. But after a while it pop's out. Values what I noticed was =0.0° (green type, others was white), -0.5°, -1.0°, -2.0°

Ok, here is a test report from H2testw v1.4

Warning: Only 30591 of 30592 MByte tested.
Test finished without errors.
You can now delete the test files *.h2w or verify them again.
Writing speed: 62.6 MByte/s
Reading speed: 63.1 MByte/s
H2testw v1.4

Maybe problem is in file system (fat32, nfts, exfat) on SD or
allocation unit size (16KB, 32KB, 64KB?)

Have you installed the RAW module? Once you do that, then you have to actually go in the video menu and turn on RAW and set the resolution.

Hi guys. I'm new here, so first THANK YOU to a1ex, nikfreak, nanomad and all others who participate in develop ML.

Absolutely. Thank you to all those who develop Magic Lantern, including a1ex, nikfreak, nanomad, the fact that all this fantastic software is free is just amazing. Thanks for all your hard work on this. You guys are the best!

Scroll over to the Modules list in the ML menu (think it's like third from the right) and click on the one that says raw.

NTFS won't run at all inside 70D. The cam will ask you to format it. Cards with 30/32 GByte will be formatted with FAT32 by the cam. I never heard of block size errors with Canon cams.
Alas, there has to be a cause for this.

Format the card using your cardreader. Insert in cam and format again. Back into cardreader again and run EOScard to make card bootable. Delete ML directory and Autoexec.bin (if any) and copy extracted alpha contents to card. Insert card into cam and startup. Results?

These are just wrong values.

If you want to get picky, it's actually the Canon values that are wrong. The camera uses 1/8 stop increments internally, so 1/3 stop increments are actually approximated to the nearest 1/8 stop. So if you calculate based on the true aperture in 1/8 stop increments (which ML does), you will get the values you are seeing.

f-number = sqrt(2^AV)
ML | Canon
sqrt(2^(5 + 3/8)) = 6.44 | sqrt(2^(5 + 1/3)) = 6.349
sqrt(2^(5 + 5/8)) = 7.03 | sqrt(2^(5 + 2/3)) = 7.12
sqrt(2^(6 + 3/8)) = 9.11 | sqrt(2^(6 + 1/3)) = 8.97
and so forth...

The same goes for shutter speed. So, if you don't believe me that Canon is lying to you, then set your camera on 30 second exposure and time it with a stop watch.

First and foremost, thank you so very much for all the hard work everyone involved has put in!

I have downloaded and successfully installed Alpha3 and will do a full report later on what does/doesn't work...

But while reading though this whole forum, I am left wondering the same thing as andrewcrane...

Quote

I've heard that the 70D can't internally write fast enough onto cards, regardless of the cards write speed, for continuous 1080 RAW. Would an external recorder, such as the Atomos Ninja Star, be a solution to this? Or are these devices only able to record ProRes?

It appeared that people seem to say that the card writer speed is not fast enough... is this true? if so could someone explain how older cameras would be able to output at the correct write speeds and not a camera that is seemingly newer? (i am just not sure i understand the process behind writing raw v. compressed and how fast the write speed needs to be...)

any info or a point in the right direction would be greatly appreciated!

Walter Schulz · « **Reply #362 on:** February 12, 2015, 11:30:54 PM »

Write speed needed in RAW/MLV:
Vertical pixel * horizontal pixel * bit depth * frame rate / 8 -> Byte/s

Bit depth for Canon RAW is 14 bit. Division by 8 to get bytes instead of bits.

Example
1280 * 720 * 14 * 24 / 8 -> 38707200 Byte/s -> 36.9 MByte/s

thank you Walter Schulz, that definitely helped.

So the card write speeds seem to be just above 40MByte/s... (based on things that I have seen other people posting in this form from benchmark tests...)

so then there is no way that full 1920x1080 RAW/MLV will be possible (based on hardware limitations) on the 70d?

if so thats a bummer, but I was really the most excited about audio features that will come with a later release...

pa0los · « **Reply #364 on:** February 13, 2015, 09:24:48 AM »

I don't believe anyone answered my question.
Is this to be expected that we can't crank up the FPS?
I tried it only with H264 - maybe it applies only for RAW?

Quote from: pa0los on February 11, 2015, 08:52:55 PM

I tried the FPS override with Alpha3.
Couldn't get this to work with FPS higher than 25 - real FPS was always showing 25.0
Seems to be working only when reducing FPS value.
Is this normal?

nikfreak · « **Reply #365 on:** February 13, 2015, 10:01:25 AM »

paolos read 1st post. it's noted in changelog.

Filip · « **Reply #366 on:** February 13, 2015, 01:58:38 PM »

Sorry about the repeat question but is it normal for the intervalometer to not be working in M mode?

If not can you let me know if there is a specific way for me to share more information about the issue (sorry I'm pretty new to ML).

Thanks!

OK, thank you for explanation. It's not a big deal. I can live with that.
BTW 30s exposure took 32s

FireM · « **Reply #368 on:** February 13, 2015, 03:45:07 PM »

ok, after i tested it some days, i found a Problem with starting Magic Lantern.

If i turn the 70D on, it happens, that sometimes Magic Lantern doesn't react und doesn't started.
I have to turn it 1-5 times on and off to get it work. Mostly it happens, if i turn the camera in Movie Mode on,
but sometimes it also happens after waking up from standby.

Haven´t saw a similar problem until now, am i the only one? Or is this a know bug ?

nikfreak · « **Reply #369 on:** February 13, 2015, 04:05:04 PM »

FireM I never encountered your problems and I am switching on / off cam a dozen of times while testing.
Try to reproduce it and note down when it exactly happens.
It might be that your cam crashes or the display gets powered off but the cam is still active? Any crash logs on your sdcard? Next time it happens try also to remove battery and retry. Maybe also reformat your card and start from scratch to see if it happens again...

ML nuisance not install on my 70d, why

Abe · « **Reply #371 on:** February 13, 2015, 07:10:57 PM »

Also did a temperature tests.
A 34 min time frame, 1 shot per minute.

Code: [Select]

Did not insist on higher temperatures, the back of the camera was getting warm.

Hope that helps.

ok nikfreak, i will test some things, and wrote my resoluts down
