If that is true, inwould return it as is does not meet the standaards.
Nothing wrong with it... the 650D is the bottleneck. I remember values from 39MB/s to 42MB/s in the ML card test.

Please note that the red card is a class 10 card, and the gold is not.
Unlike this gold one, which is class 10 too...
The 32GB version is in my 650D and has a write speed around 40MB/s
Quote from: jbassoc on August 25, 2013, 06:19:42 PMMaybe we could some how clarify the install instructions to emphasize only installing the files and folders inside the unzipped magiclantern-XXXX folder, not the whole folder.
That depends on the software you are using to unzip, not on the zip package.

Often the unzip process starts with an option to select a place where you want to unzip the contents. Default this could be set to the location of the zip file + name of the zip file as an extra folder.

Everything you need is in the first post of this thread...

If I'm not wrong I missed the part about EOSCard in your description.

Also I can confirm that. How long can it take when specified too little info ;)
All the info was there for a few days already (august 20), but I guess you didn't read it anymore.
Share Your Videos / 650D Crop Movie - The Moon passes
August 24, 2013, 05:31:00 AM
Just a little try-out to see what Crop Movie brings for tele purposes

Nanomad... maybe it already came to your mind, but I think that 700D and EOS-M may have the same problem because they use a similar Hybrid AF CMOS... and maybe 100D also, which has type II of this chip?
Feature Requests / Crop Factor Display for Crop Movie
August 23, 2013, 09:56:25 PM
Would it be possible to expand the "Crop Factor Display" setting with an extra option for Movie Crop mode?

650D Example:
Crop Factor Display OFF: 100mm
Crop Factor Display ON - Full chip: 160mm
Crop Factor Display ON - Movie crop: 432mm <-- New option?

... or make it standard when Movie crop mode + Crop Factor Display ON are set.

Maybe the error can be removed by excluding/disabling AF-points outside the crop-area?

Good job. I can now confirm it with the 18-55 IS STM (no issues with the non STM version)

Now, what should we do? I think we can issue a warning if crop mode + flexi zone + servo AF is on.
Thanks for confirming! It makes me feel better because I now know that my lens has no defects.

What should be done?
Hmmm... I think it would be great if the cause could be removed, but a warning to the user would be nice for the time being! :)

He has movie servo enabled. That disarms follow focus
Ok... but now I still don't know if there are more people with EF-S 18-135 STM who get the freeze-error with the setting "AF method: Flexizone - Multi"

To be clear... the error depends on 3 settings instead of just the 2 settings I mentioned in the first post.

Canon menu:
AF method: Flexizone - Multi
Movie Servo AF: Enable

ML menu:
Movie crop mode: on

Your (nanomad's) EF-S 18-55 would be interesting to test, to rule out that the problem is there with all EF-S STM zoom lenses. At least it is not there with the prime 40mm STM.
I love the enthusiasm. Not all at once please!  8)  ;D


Other AF problems with the same lens:

No, I can't confirm this. It works fine for me.

Quote from: nanomad on August 19, 2013, 09:54:12 PM
Can't confirm either using the "tiny" 18-55 IS STM

I don't like to waste your time, but I'm very curious how your test results are with the "AF method: Flexizone - Multi" setting, as described in my previous post.  :)
Okay... While thinking about how the AF could be disturbed in Movie Crop Mode, I did some further testing... and found another setting that has an effect on the freeze-error.

Canon menu:
AF method (above Movie Servo AF): FlexiZone - Multi

There's no temporary freezing when set to Tracking or Flexizone - Single.

So, the correct test conditions are:

Canon menu:
AF method: Flexizone - Multi
Movie Servo AF: Enable

ML menu:
Movie crop mode: on

EDIT (further thinking):
The manual says that 21 AF-points are used in video mode / Flexizone - Multi (25 AF-points in 640x480 resolution)... and I'm sure they are talking about the full imaging chip instead of a cropped chip. So this would mean that active AF-points outside the crop-zone could drive the software crazy because of receiving strange unexpected data while trying to find the right AF-point... or the other way around; It tries to auto-select an AF-point that is outside the crop-zone... I guess...? :o

BTW: CPU info from ML Debug menu keeps indicating 60-62% activity (at this moment... yesterday I saw much higher values) and it doesn't change significantly during/immediatly after a short freeze... at least not visibly. The measurement might stop when the software is looping (freezing) for a short moment?

So, you know what to do, it's time to use the warranty :)
That's the first thing I thought about... and I realized that they will send it back to me with the message:"Nothing wrong. 80 euro's please.", because there is nothing wrong when you use it without ML. Servo AF works fine without Crop Movie  ;D

QuoteBut, do you see the frame freezes on the cam display while recording?
Yes. Identical to what will be recorded.
I have been a programmer on various systems and languages for about 30 years... And somewhere in my subconscious raises a voice telling me that perhaps the 650D AF-sensor may be distorted/cut-off in video crop mode. But then... I don't have problems with the EF 40mm STM, which uses the same AF-system (distance / contrast meassurement).

I didn't study the Canon DSLR technology (yet), so it's just a feeling... but I learned to listen to voices from the subconsiousness when debugging hard- and software troubles  ;D

No, I can't confirm this. It works fine for me.
Which build? Which SD card? More info please.
Currently I'm using your ML_N_19.08.2013 (and update on a regular base), but I first noticed the problem with the very first 1.0.4 update.
I did use the ML 1.0.1 version, but I bought the EF-S 18-135 IS STM after updating the camera to 1.0.4 and while waiting for the compatible ML. Crop Movie was introduced in the same period, but I was not able to use it because of my camera update.

Lens Firmware: 1.5.0
IS and AF both enabled

SD card: SanDisk 32GB Extreme Pro 95MB/s

There's no problem with my other lenses.

BTW. I forgot to tell that the problem is most noticeable in fast panning scenes or scenes with a lot of activity.

Example video I posted 2 weeks ago (just sweeping the camera):
I have a problem while using 650D + EF-S18-135 STM in Movie Crop mode.

Settings Canon:
Movie Servo AF: Enable

ML Settings:
Movie Crop Mode: ON

In the first few seconds there is often no problem, but then suddenly the picture freezes regularly about half a second, thus producing still images during video recording.

Now when I switch off one or both of the above two settings, there is nothing to worry about and the recording is ok.

Can other users of this lens confirm the problem?

EDIT August 23:
Error has been confirmed with these settings:

Canon menu:
AF method: Flexizone - Multi <-- this was not included before
Movie Servo AF: Enable

ML menu:
Movie crop mode: on

They also need vacation so I'm guessing they're on Ibiza now to spend the donations in an appropriate way  ;D
Quote from: dngrhm on August 08, 2013, 04:37:09 PMUPDATE TO 1.0.4

Hello dngrhm,

I see you have the EF-S 18-135mm f/3.5-5.6 STM lens.
Did you already try to film something with this lens in ML Movie Crop mode?
I experience short pauses in the recording when using this lens in crop mode during moving or panning.
Would you be so kind to test a few seconds with this lens while moving the camera fast? (like in sweeping / shaking / fast panning)

Checked out firmware description (which also points at nanomad's lens)

1. Fixes the following phenomena which may occur when the camera is used in combination with certain lens models equipped with a stepping motor.

◦ Affected lenses: EF-S 18-135mm f/3.5-5.6 IS STM / EF-S 18-55mm f/3.5-5.6 IS STM

◦ The camera may freeze in rare instances if you try to shoot with a lens cap attached or meter a subject in  low contrast in Live View (or Movie) shooting.

It looks like there's a temporary freeze instead of freezing completely.

Well I tested it with the 18 55 is stm and it's fine.
So it seems like it is only the 18-135 STM for which the firmware 1.0.4 solved some problems... (if I remember well)
Quote from: nanomad on August 05, 2013, 07:15:13 PM
Well, can't reproduce it. Maybe it's the lens or the card (did you do a low level format?).
Yes, the card was low level formatted.

But... I did some further testing with other lenses.

EF-S 18-135mm STM IS has this problem, no matter if IS is on or off
No problems in standard Canon (non crop) mode.

EF-S 18-55mm IS II (kitlens): No problem
EF 24-105mm L IS USM: No problem
EF 40mm STM: No problem
Quote from: nanomad on August 05, 2013, 05:55:36 PM
Upload a video with the issue. I can't reproduce it
Just start recording and then sweep your camera randomly up/down/left/right during recording.
I see the pauses during recording on the display, and after recording during playback.

EDIT: Lens used EF-S 18-135 IS STM, IS enabled
