Oh, I did all the tests in photo mode without liveview, with mirror closed. I mean the ML interface get corrupted. Don't know why I wrote liveview, maybe my mind was somewhere else.. sorry :)

What software do you recommend to test a card on PC?


About speed - for example, when I record in raw, it stays at 20mb/s for about 2/3 of the time, but sometimes it drops to 10 or even 5-7, so the common speed is always lower than 20. Maybe same thing happens during the test..
The speed fluctuates all the time with all SD cards, even if I lower the resolution sometimes I can record for example only ~240 frames, but sometimes ~360. And it is not consistent every time.
Which is very strange because 5D2 for example can do almost exact amount of frames over and over again +/- one frame.

Okay, I will provide another patch_ap version, to force the selected value (for the left digit), hopefully the value wouldn't change during the tests.
It seems that it changes the value only after one recording. I tried to record raw video with "print value" active, and it holds it's value during recording. only switching to new value after recording stops. But the speed is always worse in these three modes (0, 4 and 8 ). Although I need to test it more, now battery is charging. And other values stays as is.


p.s. before battery discharged, I tried to record something in raw with 0x7000003, and it seems like it is slightly better, again. I am not sure, because the numbers are different every time, but for example I tried to do about 10 recordings with default value and I could record 60-80 frames every time, and 85 frames ONCE. But with 0x7000003, I've got 85 frames 4 times, but sometimes it is still only 62 or so. So it seems slightly faster, but I am not sure.

Maybe I should try 0x700000X with X something without zero in second lsb, because it doesn't work when I tried 0 and 4 which is 0b000 and 0b100, everything goes black with 1 which is 0b01, but 2 works (0b10) and 3 too.
So I expect black screen at 5, working at 6 and 7, and corrupted display at 8. and then again black screen with 9 and so on.

Very interesting... I made some tests with 550D using some adata micro-sd, can't say exact model name, I don't remember, but manufacturer's speed ratings was I think around 60/70mb for r/w. It's the fastest sd card that I have.


for the left 3, this one:
0x3000003
   ^

What I found, if I override it with 0x4000003, then it goes to 0x7000003 after the speed test, when I override with 0x8000003 it goes to 0xb000003.

so I think, 4 is 0b100, and 8 is 0b1000, and it seems that camera doesn't like zeroes and switches these numbers to 0b111 and 0b1011. (7 and b)
0x0000003 also switches to 0x3000003. so 0 to 0b11, as expected.





stock
write 15.5
read 21.9
write 15.7
read 21.9

0x2000003
write 9.1
read 11.0

0x1000003
write 6.4
read 7.4

0x4000003
write 14.4
read 21.9
write 15.9 <-- this is different, I think camera already switched to 7 after first write test
read 21.9
this is where I noticed value changed to 0x7000003!

0x5000003
write 6.4
read 7.4

0x6000003
write 9.1
read 11.0

so 5 and 6 are the same as 1 ans 2, which is logical in binary.

0x7000003
15.7
21.9
15.5
21.9
about the same as stock value but sometimes rec can go to 15.9(!)

0x8000003
15.6
21.9
value changed to 0xb000003

0x9000003
6.4
7.4
(here we go again)

I also tried e,
0xe000003
9.1
11.0
(again similar to just 2)

0xf000003
15.4
21.9
F is all ones, 0x1111, slightly lower rec speed?



and tests for the right digit:

0x3000004 liveview the interface get corrupted with horisontal/diagonal lines, camera not responding
0x3000001 everything goes black (crashes?)
0x3000000 same as 04

0x3000002
15.7
21.7
seems like original, but read speed is always 21.7 and not 21.9

0x7000002
15.4, 15.5
21.7
read speed again 21.7 and not 21.9




So....... I need to do more tests to see if 7000003 is really better than original 3000003, it can go to 15.9 mb/s rec speed and original value can only go to around 15.7, but I am not 100% sure, I need to do more tests with the original. Maybe it's just doing nothing.
And for right digit, only 2 and 3 are working, and 2 has slightly lower read speed.

find out how much it will cost to replace the shutter, and count it as a potential increase in price. if it is still ok, then get the camera :)
it's 50/50 chances anyway because nobody will know for sure, but if you only record videos then maybe you can live with this shutter count..

and this site (shuttercheck) is collecting data fom users with alive cameras, which is not really the shutter life expectancy metrics... it basically shows how many photos typically were made with these cameras. lol :D
#179
cool, I want to do the same for 5D2 using the case from an old battery to make the adapter. If you have an access to 3D printer you can print some kind of a holder for the whole thing, and screw it to the bottom of the camera to the tripod mount.
#180
1920x1080 doesn't leave any margin for stabilization or cropping, 3840 even stretched from 1280 but with real 2160 vertical should be much better in this aspect.. at least I think so. Of course I can only compare it to ML 1920x1080 and not other cameras.
#181
wow, this is pure magic! congratulations!

Raw Video / Re: Best camera to choose (even for RAW)
April 06, 2022, 08:07:37 PM
only one thing - fast CF cards are very expensive these days. for example, 6D has SD card..
and 5D2 still doesn't have working 1x3, you can activate it by doing some manipulations for ~10 minutes :D, I tried it, it works, but there is no preset for it.

Raw Video / Re: Best camera to choose (even for RAW)
April 05, 2022, 06:08:25 AM
Absolutely, tiny color outline around the objects with high contrast, and you can not get rid of it by focusing. Only by closing the aperture. And if for example I'm gonna use the crop mode and film 2-2.5k footage, it will be more obvious with crop-sensor cameras...

It's not only with old lenses, there are somewhat modern wide-angle lenses in which it can be noticeable even without zooming in on the photo, so you have to close the aperture 1-2 stops if you want to get rid of these color outlines. So it's a common thing, at least for me. For example, with green leaves on trees against the sky, on the edges of a buildings and so on.

Raw Video / Re: Best camera to choose (even for RAW)
April 04, 2022, 05:49:01 PM
hmmmmmm it probably sounded too unclear, I mean in the center of a frame, especially if we are talking about crop modes. Edges are worse on the FF obviously.
I'll google it of course...

For real world scenarios, last time I did some tests. Just black text on the white paper was looking sharper using the same lens on the full frame. In the middle of the frame, when exactly in focus.
Of course I was closer to the paper when I was using the FF camera, to get the same field of view. It is how most people will photograph the same object with the same lens but different camera.

I also have some old lenses that are not really sharp wide open when used on the ASP-C, they are just a little bit soft. But it is not a problem for the full-frame camera, everything seems to be ok. Corners may be especially bad, but who cares about corners, right? :) well, I mean if somebody want them to be 100% sharp, for landscape photography or something - maybe they need crop camera and modern razor sharp lenses..
It just depends on what you want to get...
#185
This is not exactly related to cameras, but if you also do a lot of audio recordings or make custom cables for your cameras this trick can be very useful. I know many of you guys are into the electronics. So I think it can be helpful.
I hope this stuff is OK in the hardware section of a forum. I invented this interesting method of checking cables myself, and never saw anyone doing this, but similar techniques are used in industrial applications.

Utter nonsense. No evidence for your conclusion provided. No hard data -> Just "feeled truth". Nothing to talk about.
In 1:1 cropped mode you will have a hard time to tell ML cameras apart.
We bought used 5D mk2 and it was..... somewhat not exactly sharp. It almost drove me crazy, but when we cleaned the sensor the problem was solved. So I think it was micro dust particles on a sensor that stick to it over the years of heavy use. So clean your sensor, if you notice something strange. Other than that - it is just pixels. And pixels on FF body are larger so the image should be sharper even with the same lens. Less CA.

I later spoke to one guy from the service center, and he said he saw a couple of such cameras, where after cleaning the image became noticeably better in sharphess. This is not exactly the science, but I can imagine very fine dust particles (less than a pixel in size) scatters light and creates softer image. I can be wrong though.
#187
wow, initially I thought it was shot using a steadicam. I can hardly see any stabilizer artefacts. do you mind sharing your handheld technique?
#188
Well, you can try DNxHR, ProRes and DNxHR are two professional codecs for post-production.
But I think if you have a weak computer maybe it is better to upgrade the Premiere to the version where they included the ProRes support. I'm using Premiere 2018 on a 15-years old pc, yeah it is slow but it works.. And ProRes is slightly faster than DNxHR on old computers, at least in my experience.

yes you're right, I failed to record using 1 fps on the bright scene and I got error, the fps overrides always changing back and forward from 1 to 25 fps I don't know why.. the live view is so lag too.
the liveview and all stuff will work with 1fps too :o :D :D so it's better to set everything before turning the fps override on.

have you tried the original nightly build for your cam? maybe it will lack some functions and SD card overclocking, but for such low speed recording it is not necessary anyway. which makes it possible to shoot timelapses with cameras that have even the slowest SD controller.

yeah I used to film timelapses with fps override too :) It's just so easy. I think 1..2 FPS is ideal... try using shutter speeds as long as possible, 360 degree wold give the most beautiful movement. well, at least I think so, 180 degree rule doesn't really work here.
But 360 requires long exposures (1s on 1fps) so for day - ND filter is necessary.. I mostly did evening/night timelapses with auto iso, because of that.
#191
wow. so this is not only on my computer..

Two years ago I messaged ilia3101 and he mentioned.... I will just quote him (well, I hope it is ok to quote a line from PM)
QuoteI used to use MLV App on a thinkpad X61 (laptop from 2006), and I had to fix a couple of bugs that only happened on the old cpu
And I don't know, maybe it is something like this. unfortunately.
I tried to use some programs that can show some info on exe files, dependencies and stuff, but didn't find anything different from v1.12.
#192
@masc I'm using slightly cut down win 10 version (some unnecessary things disabled like store and so on). I had doubts the full version will work on that hardware.. So there is a chance something is missing, but I don't know tbh, all other programs seems to run ok.
Is there an option to diagnose what exactly happening, why MLV App quits? because it's doing it absolutely silently I can't even google the error and maybe see what could be done.

p.s. I'm gonna google what software can diagnose potential problems with running exe's, maybe I'll find something

It seems like I have all the necessary dependencies, and they are the same for 1.12 version

General Help Q&A / Re: EOS M searches confusion
March 20, 2022, 04:36:48 PM
try "EOS M"

usually including your search word in "" means that you want to search this exact phrase.

another option is to use google, and sometimes it is more convenient or if site doesn't have a search box, or if you need to register for search and you don't want to.
the syntax will be:

site:sitename.com search term

for example:
site:magiclantern.fm EOS M


p.s. I modified the message and didn't see that google was already recommended below, sorry ???
#194
Hi guys, I recently switched to a "new" (very old) computer and I can't run MLV App 1.13 on it for some reason. While 1.11 and 1.12 are working but only 32-bit versions (although I didn't check 1.11 x64).
But 1.13 just can not start, it doesn't show any error messages or anything, I can see it process in task manager for maybe a second, and then it just silently disappears.

I'm on fairly "fresh" installed windows so maybe I need to install something? like .NET or something else?
The config is (don't laugh!! :D) Intel Core 2 4400 2.0GHz so it's a dual core machine with 4gb of ram and ati radeon hd 4850 installed. Windows 10 x64 21H2 and by the way it runs ok, very smoothly. motherboard and cpu are from ~2007 so it's 15 years old :o but this is all I have for now..

@Skinny

Tried to compile a same build for 5d2, but didn't succeed, error messages and no build.
Probably because the source is the "crop_rec_4k_mlv_snd" branch, where the 5d2 is not fully supported  ???
@Levas thank you anyway :)

@ML700D but.. is this a standart canon preview? what about actual recorded raw footage?
Quote from: Levas on March 14, 2022, 08:54:07 AM
Edit: you can't see changes to raw type in canon liveview, but it will do show up in ML preview, the slow low resolution preview option available in raw video menu.
#196
@reddeercity hi! if you are still here and following this thread, could you take a look at this https://www.magiclantern.fm/forum/index.php?topic=26414.msg238174#msg238174
if you can make a build with this option enabled I will gladly test all values from 0 to 0xFF :D

Or maybe some other guys who have all necessary tools installed can do this?
#197
ok, sounds very interesting  :) I'll ask in 5D2 thread since this is the camera I'm using.. thank you for very interesting suggestion. I really like night scenes, but never go beyond iso 800 in raw, maybe 1600 sometimes but it is already too noisy.
#198
Thanks. I did some search on the forum and found other mentions, but it seems that nobody implemented this on other cameras at least yet. And I wonder why, because it could be very nice option to use in low light. Maybe on other cameras it's just different and actually working low noise raw type it is exclusive to 6D..
#199
Is this raw type option only exist for 6D? 25600 iso sounds crazy :o :D

If audio has clipped during acquisition you can't do anything about it in post, except just lower gain a bit and apply some smoothing filter to not hear that awful crackling. Anyway, information is gone and you're not gonna recover it.
there is also izotope RX de-clip, which can restore some digital clipping, but don't expect too much.. here you can hear an example: https://www.izotope.com/en/learn/using-the-de-clip-plug-in-to-fix-clipped-vocals.html
