Camera-specific discussion / Re: ML on EOS-M2

« Last post by Walter Schulz on Today at 11:02:28 AM »

According to an unverifiable source around 30 percent of all SD-cards offered by non-official dealers are faked.
If you purchase a card from such a source a thorough after-buy check is mandatory (in all other cases highly recommended).

Check for faked speed specification:
- Fast cardreader + PC + a benchmark program like CrystalDiskMark (Windows) or Blackmagic Disk Speed Test (macOS).
  You only need to run sequential R/W. Compare with benchmark runs from reliable sources like www.cameramemoryspeed.com
 
Check for faked capacity number:
- Cardreader + PC + h2testw (Windows) or f3/F3 QT (macOS)
  If capacity info is altered by some crook you will get serious data corruption because cam will overwrite data recorded previously if physical storage limit is reached. Cam's firmware (and your PC, too) rely on card's info set to be correct and will not check if data set numbers and reality match.

@70MM13 Nice work. Lovely clean shadows! How exactly are you using the colorspace transform? Be great to see a grab of your node map in DR.

I have a tamron 10-24 EF-S and it's definitely fitting inside my mark III.

I could take shots, but before reaching 16-17 I could see the black circle all around the photos, so I did use it but never under the aperture of 16-17 mm.

Today I'll try to make a raw video with that one, at 10mm / crop mode / whatever setting I can find which is working and not showing a black circle.

The crop mode on ef-s lens mounted on full frame look like a cheap trick but it may allow me to shoot nice wide videos with a cheap lens I already own.

Wait and see !

There are over 200 votes already on this poll. Not bad

I'm not going to rush anything (sorry nikfreak), but the initial reaction is encouraging. Once I'll sort out the legal details - for which I'll definitely need help - I'll announce the next steps.

Thanks everyone for the feedback!

General Development Discussion / Re: 3K/UHD 5D2 Raw development and Other Digic IV Cams

« Last post by reddeercity on Today at 08:03:02 AM »

doing some UDMA clocking on the CF Card interface with DIGIC POKE , I'm able to push the write speed to a average of 75.5MB/s  (I'm using a will used Lexar 1066x 32GB from 2014)
normally it's around 68MB/s , so peak write speed that I saw was around 80MB/s + . Seems to be a 10% increase ,
I don't think I have the right reg's yet or I need more reg's , I can change the reg's for write speed to as low as 5.5MB/s then I increase it slowly to 12 , 15, 20, 25, 33, 48, 60, 68MB/s to 75.8MB/s with different reg's valves .


So far

Code: [Select]

0x101seem to be the fastest at the moment  , I'll have to start working in the HDParm branch to see if I can clock it higher
I have the branch cloned just need to compile for 5d2 and investigate what can be done to increase write speed .

Edit: My test resolution for this was 2144x1078 @ 29.66 FPS in 14bit raw ( default ML 3x crop_mode)
so around 7-8 seconds .

No, the 480p thing was with mv1080 a lot of builds ago before we had mcm rewire. It works with mcm rewire 1080 no need to set 480 on the monitor. The M2 works well with my different monitors such as the FOTGA A50T and the Feelworld 4K Monitor F570.

"WARNING" - Just make sure you "TURN OFF" Wi-fi when using an external monitor on the EOS M2, otherwise nothing will show up

Thanks Zeek.

I received my M2 last week. I've spent that time learning ML but was mystified why I could not achieve any higher than ~1376x5xx continuous, regardless of setting (I did a lot of testing with different settings). Even worse, the performance seemed to be slowly getting worse over time. From ~23-24MB/s down to 20-21. Never anywhere close to 30. I used a brand new 128GB Extreme Pro 95 UHS-I ordered from Ebay. Finally I decided to buy another card from a local electronics chain - this time a 64GB 170 Extreme Pro. Now I get 33mb/s and continuous no problem. I don't know if the 128 was fake or a bad batch being offloaded for cheap or just bad luck. But I thought it worth mentioning.

Ok here's a little bit of libMLV: https://github.com/ilia3101/LibMLV (raw2mlv included, compiles on mac and linux, writing functionality not released yet, generally unfinished)

Quite tired from all this, macOS compiling/linking decided to break today, so I'm also going to have a break.

Yapp, exactly. I am just not 100% sure if that works without Qt libs - this would be overkill. To be tested...

Edit: if you open QtCreator -> new project -> non-qt project -> Plain C/C++ Application..." This should do the job for Win/Linux/OSX.

Thanks. I will try using that for something. I have a command program thing that is simple C, won't use it for that, as it really would be overkill. But there will be more than one program with libMLV so it could come in useful. Definitely going to use Qt for the GUI app.

I think donations will work.
Shouting out specific cams maybe not so much. Personally I don´t see the logic porting a flag ship model but thinking start off with some more modest model. If cam model is the actual start at all. Seems a robust platform and all the hard core work coding will be the hardest step before even getting into porting. That part is not so easy for the regular user to grasp but probably what takes the most time and money. And I don´t know if anyone but a1ex could get that part working in a reasonable time frame. Interesting idea here would be to estimate timespan of work needed to be done and translate this into donations. Planning...
