Hi guys! I have one theory about overclocking.... do you know why exactly card fails? I mean, if someone with oscilloscope can watch the signal on SD pins, maybe clock edges are not strong enough, or data-edges...
sometimes, in digital electronics, waveform could be improved if you add pull-up or pull-down resistors, they could be installed in the microSD to SD adapter for example.

I can't check this myself because I only have 5D2 and 550D, but just had this idea right now, who knows, maybe it is something useful, or maybe not. Maybe card fails because it cannot complete write cycle in time, physical flash technology limitation, and there is nothing we can do. ALTHOUGH.... maybe under/over-voltage could affect write times... I think it's interesting.

How much shifted would you say? Could you post a few visual examples? Unable to find time to do tests atm.

Thank you for the reply Danne! I hope this helps, I've had to delete most of the footage as I needed the space, but in this shot the subjects nose was in the centre on the camera screen, but it's to the left in the recorded video with extra space on the right that was not visible when framing the shot.

And in this one, the top of the hot water bottle was in the centre, with both sides visible. There's about 40mm missing on the left and extra space on the right (the object is about 450mm end-to-end, shot with a 35mm lens):

Please edit. Use thumbnail preview linked to full scale pic.

Oops, sorry. Is the above acceptable?

Tested shortly and not very hard but seems ok to me. Are you selecting ratio from the Movie tab and not from under raw video menu? Could help to know exactly what settings were used here.

If you could perform a more revealing test it would probably show the issue more clearly. For example. Do a photo of your liveview screen, and then record a short mlv and post your examples here.

Here´s an example with ratio 2.35:1

Looks close enough to me but feel free to show me otherwise.

Aha! I believe I selected the ratio from the raw video menu, so operator error. I'll perform the test for you a little later though, just to rule anything out. I've got some editing to do at the mo as I re-shot everything in MCM 1080p Rewire which looks fantastic :D I chose 5k anamorphic last time as I'd had some problems with aliasing when the subjects were wearing shirts with rough stitching but there were no such artefacts today. Thanks again - for the response and the project - we have literally no budget at all and wouldn't be able to do what we're doing with such gorgeous footage without Magic Lantern.

Happy to see the results later. Please share if possible.
Aliasing less with HD 1080p(mcm rewired)? Must be a lucky coincidence. 1x3(anamorphic modes) will outperform HD 1080p per always I would say ;). Especially on aliasing side.

I will do! I don't think I explained myself correctly before, MCM Rewire had aliasing on the rough-stitched shirts shot with a 35mm f3.5 SMC Takumar stopped-down to F8 on a sunny day, which is why I chose 5k anamorphic for the interior shoot yesterday. However when I re-shot today (we were in a hurry) there was no aliasing with MCM Rewire, I'm guessing because of the fine stitching on the blouses they were wearing and the wide-open old zebra Pancolar I used providing a touch of softness to mitigate it.

I also tested 5K frtp here, and also in 16:9. I get (in the MLV) what I see (on the liveview).

Great masc.
Yes hd 1080p is not bad. Most shots will work just fine. Zeek uses this setting a lot. To me 3x3 binning fake sharpens footage too much for my liking but I have been comparing ml footage way too long now  :P 8).

Thank you masc, I really do think this is my error but I'll certainly do the tests and replicate what I did wrong!

The 5k 1x3 does have a delicious creaminess to it but I'm more than happy with today's results!

Does anyone know how to remove focus pixel maps if I use dng files workflow in davinci resolve ?

Only in the step when transcoding to DNG, so in MLVApp or MLVFS. Resolve can't remove that.

Hello everyone. In 2020 I decided to start videoshoting with eos M. To set magic lantern for it, I need a 2.0.2 firmware, but I can't find it anywhere on the internet. It just doesn't exist. Can someone give me some link to download it or send 2.0.2 archive, please??? I just can't use my canon with latest firmware(

So if i output as cinema dng from mlvapp, there is no way i can remove the focus pixel maps later? because any edit made in mlvapp doesnt apply to cinemadng

Right.

Then you did something wrong. All RAW corrections will be applied. You probably exported via "fast pass" ( = bypass without any changes ).

Hello everybody, I have two problems with ML NOV20 build.

1) I can't use my lens in AF mode while using 5K frtp. It just freezes the LiveView and doesn't focus on anything.
2) I can't use HDMI output to my phone with a capture card for 1080p mode or for 5K frtp mode. On 1080P mode, I get a black screen with no overlays. ON 5K frtp, the overlays work but I see pink distorted lines instead of the video feed.

Do you know any solutions for these problems?

1) Skip af when working movie modes. Treat eos m as a manual focus cinema camera for best results.
2) Skip HDMI out altogether when filming with eos m for best results.
If any of above works with af on or hdmi out consider yourself lucky.

@ZEEK posted a video just a few hours ago that includes how to get an HDMI monitor working with the EOSM.

Yeah, that guy is really testing those presets out 8).

Well, instead of just discouraging someone by telling them to skip altogether trying to use an HDMI monitor with ML, @ZEEK helpfully:
  • advises which ML presets are ideal for HDMI;
  • shows how to adjust the ML settings within those presets to eliminate HDMI problems;
  • and instructs on how to get the best framing from a monitor.

Well, that´s what I like with magic lantern. When users finds ways and do the unexpected. Personally I still think af and monitors with eos m is way too much hassle than recording without.
Then again he asks for usage with his phone. Don´t know if that´s possible.

I have to give much appreciation to the developers who have done a fantastic job coding these things for considerably some time. It can be a lot of work for sure! And a lot of things with ML can be unpredictable.

We can't expect things to work straight off the bat, which is why these builds are experimental. Feedback from users with uploaded samples is highly recommended to fix some of the issues.

As for HDMI stuff with Monitors, it can be like playing with fire. The 2.5K HDMI Preset is the best for high resolutions as I have yet to see a dropped frame after a few 1-minute or so recordings. 5K FRTP is also quite good. 1080 mode has it's ups and downs.

Using your smartphone as a monitor with the EOS M is good for 2.5K/2.8K RAW, zero dropped frames and clear image. Other modes go blank. The best would be to test with different capture cards.

But as Danne said, HDMI Monitors will present more issues, I have just tried to exemplify what I have done as I like to use monitors to record myself when sampling lenses for skin tones on different RAW Modes.  8)

Thanks, everyone for all your replies. My post wasn't approved for a while and in the meantime, Zeek has replied to my comment on YouTube.

As for the result, I guess I knew what I was going into when I decided to shoot with an EOS M as opposed to my smartphone  :) Even though it's cumbersome at times, I learned a lot. I didn't even know what an aperture was before all this :D
