Mooi!

Love the colors and atmosphere.
Can we have more tech info? Camera, lens, ML settings, etc.

P.S. Noted hot pixel at 2:37-2:45 almost in the middle of the screen, same for Richard video from 0:56 till the end.

Really great!

Can we have more info? Camera, lens, raw specs, aerial shots, workflow, etc.

I just tested it and the 700D can do a little better than that. Continuous recording at 1280x694 50fps with 10-bit lossless compression with crop_rec 3x3 is possible.

Well this sounds promising. Thank you for your time running a test.

The only other APS-C small camera that can do the crop_rec with lossless compression thing is the 100D so you do have options.

If won't find 700d for a good price (I really like an articulating screen), will definitely go for 100d (hey, same battery as EOS-M, got bunch of them). Thanks again!

This one requires lossless compression. EOS M and 700D do share the same card interface specs: SDR50/UHS50 (about 50 MByte/s). Without compression required bandwidht exceeds 40 MByte/s (pure RAW/MLV without H.264 proxy) and I haven't seen continuous recording at this rate.

I'm fine with compression, I'm fine with 8-bit, I just wasn't able to get it working on EOS-M at 50fps. And continuous is not necessary, about 60 seconds would be enough.
I was testing at 960x402px different combinations of bit depth and compression, it tops at 32MiB/s with 14bit no compression, and no luck

I thought that 700D might have more progress in shooting 50fps, since it have "native" m720 mode, on EOS-M it's only turns on with h264 proxy, without it it's only 30fps.

If you have an EOSM you can try the crop_rec module and push up the FPS override a bit to approximate what you will be able to get on the 700D. Internally these cameras are very similar, same sensor, focus pixels, SD card write speed, etc. The big difference between the two cameras is being able to record mv1080 on the 700D but you can't push that to 48+ fps. What exactly are you expecting out of the 700D?

I'm quite happy with the EOS-M, the only thing I miss is slow-mo. And it's VERY slow in photo mode.
I tried to get 50fps on EOS-M on few latest experimental crop_rec with h.264 proxy enabled, but no luck. On lossless I get console warnings, and on 10/12/14bit RAW just black or corrupted frames.
IIRC 50fps can be only reached from m720, does 700D has m720 with 3x3 option?

So my goal is something like 10bit RAW 1280x536 48/50fps with 3x3 binning, so I wanted to know does it work already on 700D, because on EOSM it doesn't, at least for me at this moment.

Hello 700D owners,

I'm thinking of buying 700D as main camera, and there is one thing I want to check first. Does it shoot 48+ fps 10/12/14bit RAW/ lossless? And if it does, what approx. resolution it can reach?

Thanks.

whole back panel with buttons can be replaced, but it's quite expensive, something like quarter of this camera budget:

other option is this:

https://aliexpress.com/item/NEW-Keyboard-Key-Button-Flex-Keypad-Cable-Ribbon-Board-for-Canonn-EOSM-For-Eos-M-Accessories/32823812820.html

Looks like HW issue. Mine sometimes skips pushes. Works one time on every second or third push. Sometimes ok.

EOS-M

As we know crop_rec footage should use a replacement list. A list that is only used in Switch atm for all I know.

Did I understand it correctly, that at this moment only Switch is able to fix focus pixels on crop_rec footage (720 3x3 on EOS-M in our case)?

Sorry, language barrier 


About 48/50/60fps on EOS-M for this moment I fail.

setting in Canon menu 1280x720p50
enabling mlv_lite raw resolution 640x268 14bit/14bit lossless/10bit (for some reason 10/12bit lossless is not available)
enabling h.264 proxy with CBR 0.1x

and most of the time I get a lot of error messages and only battery pull helps out.
if it records something it's actually 50fps, but corrupted frames (black with vertical lines).
without proxy it's always 29.973, and with fps override it tops at 31.2xx


Offtopic: Does 700d/100d manage to shoot 48/50fps RAW? I was planning to get a 50d (no focus pixels and CF card), but if 700d/100d can do slowmo with 10/12bit lossless - that would be a huge plus for me.

is there any working solution for focus pixels in mv720 3x3 footage?

Yes, I published the map files and they are being used in a few apps. I only tried it extensively in Danne's Switch and it is working great.

Thanks! But I had to tell that I'm on Windows, sorry 
I tested MLVProducer build 3151, it removes focus pixels in the center (profile 80000331_1808x727), but leaves some at sides. And vice versa with profile 80000346_1808x1190. I thought it might be using an old version of your EOS-M profile and downloaded it from bitbucket, but unfortunately it uses some different format (not plain text as yours).

Is there any other option for Windows user besides MLVP? Can mlv_dump do that?

P.S. Looks like I need to find my old laptop to install Linux+Switch on it 

Extra question: Is it possible to get 48/50fps in RAW (resolution is not very important)? Mine tops at 31.something, may be I'm just doing it wrong.

Experimental crop_rec_4k.2017Oct02.EOSM202

Installed experimental crop_rec ML from 14sep2017 on my EOS-M.202
mv720 3x3 is working great, but now I have a question: is there any working solution for focus pixels in mv720 3x3 footage?

Thanks for the info.

How about 60 fps? Should I use canon menu to set the frames and fps or use ML fps override function?

And what framerate you're using and need?
Use this calculator to see approx values http://rbrune.github.io/mlraw/

1080p30 is 103.8MB/s
1080p25 is 86.5MB/s
1080p24 is 83.1MB/s


MarkIII CF card max write speed is 100MB/s, so 24/25 fps FullHD will be recording till card is full (also don't forget to switch to exfat if you didn't, to write 4+Gb files).
For 30fps you'll have to go for 1856x1044 (16:9) or lower. Or use wider aspect ratio.

@rbrune

Sorry for some offtopic

As I understood you managed to switch subsampling inside of mv720? So it might be possible now to make 48/50/60fps RAW on 5D3 without stretching using same method?

Finally EOS-M is just about to become little video beast on steroids Thank you, Rafael, for your work and time!

P.S. Unfortunately I wasn't able to open that google drive link

P.S. I would love to shoot in crop mode (fantastic quality), but it need's fast wide lens and I can't afford it at this moment.

I change my mind about RAW in crop mode, I don't like it at all. The first impression was good, but after some more tests... yeah it's 1:1 and no lines skipping, but it becomes soooo soft, even with very sharp lenses and noise grain also now 1:1

So, is there any chance to get mv1080 in some near future? Or is there somewhere an information about that, just to know if it's in the plans or not? Anyone?

Do you mean in Adobe Premiere?

I want to fit the whole image, not scale so it zooms in.

I'm shooting with a Mark III

Here's an example of what I shot. I would like to fill the whole from 1280x720

Oh, I didn't notice it was 50fps, that's the reason. It's in 1280 x 720p (60/50fps) mode "mv720" where it squeezes image vertically. Long story short you need mv1080 (24-30fps) for normal aspect ratios, in mv720 you'll need stretch vertically x1.67 in post to get your aspect ratio, then upscale to your final resolution.

http://www.magiclantern.fm/forum/index.php?topic=5472.0

Stretch image vertically by x1.67
What your shooting with? EOS-M? If so than non stretching video is only available in crop mode.

love this little camera

@dfort

Your ideas aren't stupid. In fact it is along the lines that a1ex, the main developer, suggested to get mv1080 working on the EOSM.

h264 1080p @ 0.1x bitrate takes about half megabyte per second + PCM stereo 48/16 audio up to 0.2MB. So it's less than 2% from EOS-M SD module write speed (I have card with bit overkill). I'm fine with that, just hope that CPU can handle that.
Do you know if fixing mv1080 on EOS-M is in the plans for some near future or should I save the money for other camera like 650D for example?

The little color dots you're seeing and possibly the vertical color lines may be artifacts from the focus pixels. It was an interesting journey dealing with focus pixels. I ended up mapping all of the focus pixels for the affected cameras starting with the EOSM and @dmilligan coded a fix into MLVFS. I assume that @AWPStar is using the same algorithm in MLVProducer. Basically to hide the focus pixels the surrounding pixels need to be averaged. Dual ISO was a problem because of the alternating horizontal lines of light and dark so the averaging is only done on the pixels in the horizontal axis. This usually works fine until you get into fine details that are one pixel wide. That might be what's causing those vertically colored lines.

Yeah I read that few days ago, because that was the very first problem that popped up in testing RAW. Great job done, thank you!
BTW need to compare to 720 h264 for color moire... Because 1080 h264 didn't have that.

What is unique about the EOSM in crop mode is that you can use C-mount lenses. There's a bunch of cheap fast lenses out there though the quality isn't exactly fantastic. On the plus side crappy lenses do tame moiré. There are some nice quality vintage C-mount lenses made for 16mm but it seems that collectors are bidding up the prices on ebay.

I did some quick search for C-mount lens on ebay and Aliexpress, but most of them are noname 25mm+ (160mm equivalent in crop mode). And I need something in 35-80mm eq. range. Also looked for vintage USSR fisheyes, but they are very rare or not fast enough.

Looks like I'll have continue to shoot in flat h264

P.S. did compare test



in fact I can see red and blue cast on 720 h264 at the same place like in RAW, but codec's blur hides it (plus flat cinestyle profile) and it becomes not so noticeable.

P.P.S. yeah... mv1080 would solve lot of issues...
Just one more thought:
I read somewhere that mv1080 mode turns on with beginning h264 recording. <stupid idea>CPU probably won't handle it, but still, what if we set lowest h264 bitrate possible (CBR 0.1x or VBR Qscale 16, may be something even lower is possible) and write both h264 + RAW? (we can also grab audio track from h264)</stupid idea>

Hi everyone!

I was testing a noncrop RAW video recording and got a problem.



This is a screenshot 200% crop from MLVP (same situation in ML RAW Viewer and RAW2cDNG). I understand, that it's canon's downscale with skipping lines, plus ML squeezes image vertically, which leads to heavy moire and ladders. But where did these false blue and red pixels came from, looks like color moire? Is there a way to fix it while exporting RAW (without post in LR or PS)?
Shot RAW 1728x434 ISO 320 50mm f/2.8 (same thing at all ISO settings)

P.S. I would love to shoot in crop mode (fantastic quality), but it need's fast wide lens and I can't afford it at this moment.
P.P.S. Sorry for bad english
