theBilalFakhouri, thats whats happens to me with both of them, using win11, hopefully one day a codec/decoder is available that alllow us to quickly open an mlv file with mpc-hc/mpv/vlc, mlvapp plays them but a bit too much for a specific task like preview/play.

Thanks for helping out

Reddeercity, just using normal mlv files recorded with eos-m in 1080 mode

Thanks for helping out

Did you try this ? not sure if this is supported in win10/11(worked in win 7pro)
The colors kind of mess up but played the file find , good enough to view file

Hi, ive seen the thread you started back in 2016, ive hunted ffmpeg/ffplay builds from that same year/month but they only play audio, do you still have a backup of it that you can share?

Ive tried MPV and it doesnt play mlv files

@ricardopt

fastcinemadng is MLV player too:

Sure it plays mlv just like mlvapp but i just need a player, i dont need to be opening a full converter app just to view/play an mlv


Looking for something like described here by reddeercity, tried hunting for older ffplay builds but all they play is audio; Danne also suggests mpv but it doesnt play mlv.

https://www.magiclantern.fm/forum/index.php?topic=18392.0

Lets say you have a big collection of mlv's spanning several years, what do you use to play them?
Thanks

Thanks theBilalFakhouri for your suggestion, as far as i can see fastcinemadng is a mlv converter just like mlvapp, what im trying to find is only a player, it doesnt have to be realtime etc etc, all i need is something that allows me to see what i recorded on a specific mlv.

That's the right document. I've seen it before, but thanks for digging it up.
I've translated the scene linear to F log curve in to MLV App's expression format. Here you go:
(x < 0.00089) ? (8.735631 * x + 0.092864) : (0.344676 * log10(0.555556 * x + 0.009468) + 0.790453)
......

thanks for yours and everyone's help, i done some tests and here's a video with side by side comparisons, all done in mlvapp, no color grading, just default values with exposure tweaking, only used an NLE for titling and "fx".

1 - mlavapp to f-log
2 - mlvapp with the f-log formula + AgX + fujifilm lut"
3 - mlvapp with tonemapped profile + AgX

Some videos look identical, others with f-log+lut look more "whitewashed" than the tonemapped ones, all a matter of personall preference i guess, look alike a good option for mlvapp.
Once again thanks.

You can implement F log yourself. Select rec2020 primaries(F log uses them), then write the log curve formula forums as transfer function (you'll need to google it to find the formula).

Hi ilia3101, ive looked/searched online but couldnt find any info about it. Do you know any specialized forum where i could find or ask for that info, almost all results point to logarithimic curves but thas nothing to do with video, the only result i could find was a pdf on the fujifilm website but cant make "head or tails" on how to write that formula, can you help?

Managed to get MlRawViewer  "working" by instaling Microsoft Visual C++ 2008 Service Pack 1 Redistributable Package MFC Security Update (x86)

https://www.microsoft.com/en-us/download/details.aspx?id=26368

but it doesnt recognize or play (drag and drop) mlv files

Hi everyone.

Ive been "collecting" aq lot of mlv files, got them all sorted in folders by year/month so far ive been using mlvapp but all i wanted was a quick double click player to find out what is recorded on a specific mlv and zapp through folders.

Tried MlRawViewer but a sxstrace error pops error, ffplay doesnt play them...just audio.

What are you using to quickly view mlv files? Im on Windows 10/11 64bit.

Thanks

Thanks for your feedback ilia3101 and Danne.

I dont have the technical know how to say if f-log is worth it or not, i've been playing with some xt3 and xt4 f-log and eterna video samples and it looks ok, just exploring some other "color sciences" instead of the usual ones.


Thanks for your advices and input.

I think you can try this : exporting with Alexa Log-C preset from MLV App, and then in Resolve Davinci, with the plugin CineMatch, you can easily convert the resulted Arri Log video to a F-Log curve.

Thanks for your advice wib, will try the free trial as its expensive for me, have you tried it? 1GB download for a plugin?!

Hopefully one day mlvapp will support exporting to f-log.

Once again thanks for your advice

Hi everyone.

Is there a way or does anyone know a lut that can "transform" any of the log formats to f-log? like sony slog to f-log? Or is that not possible?

Thanks

I don't get what you don't get.  A "1920x1080 1x1 RAW"...(explanation) If you still don't get it, I don't know how to make it clear to you.  I am giving up, sorry.

Hi IDA_ML, its not just him, there's more people confused with the terminology used here, this is a canon eos-m thread and people keep using terms like "crop factor" for comparing with full frame sensor and then crop factor for recording video modes where only a croped area is used and people tend to get confused about what is what, i know this is for advanced users but people have to start somewhere.

I think everyone apreciates all the help/dedication/time that developers put on ML and still answer questions here...its priceless all the help given here but i think its normal for people to get confused with terms being used to describe 2 different things.

I know its a thread for advanced usage...just my 2 cents.

Try to desaturate your shadows (dark areas). It has too much red color in it

Hi, thanks for the advice, it was an "artistic" decision, but yes its too much red, redone the edit in Premiere but didnt get much sucess with it, tried davinci resolve with cdng source from mlvapp and i managed to get a more pleasing/natural video.

With Prores sources and Premiere



With Cdng source and Davinci Resolve

Hi everyone!

Just a quick test with the Canon EOS-M, 2.5k, 16:9 (2192x1234), 15-45mm ef-m lens, edited in Premiere and exported to 2560x1440

Hi Walter and Danne, thanks for your help, unfortunally it was a long day at work and i'm unable to get the "right english" to explain my situation, bad day...no other way to put it, if any of you has admin rights in the forum please delete my last posts to avoid further confusion to new users, will try to explain it better tomorrow after a good night sleep.

As always...thanks.

ML never had a crop mode in photo mode other than silent pic.

i was "talking" about the video modes, some of the modes have a zoom factor, i remember reading here or on a video on youtube that using that video mode already zoomed in together with 3x times zoom that helps focusing can create good photos but i dont see how to take a pic in video mode, i remember Danne writting about an 8bit option that when selected would enable the user to take a picture while in video mode.

Thanks for your help.

Hi everyone!
Was trying to get some photos of the neowise comet with the EOS M and its working perfectly, if i zoom on the moon 10x and take a photo i don't get the zoomed version, is there a way/hack for this? i remember people talking here about using one of the croped video modes to take a photo and simulate the zoon effect? i tried but i might be missing something because it doesnt work.

Can anyone help?

Hi everyone!
Got carried away yesterday testing the 15-45 efm lens and got lost in the settings i was using so i ended up with different aspect ratios/resolutions, altough people downplay the 15-45 IS EFM lens i think its better than 22mm efm prime, here's the video with annotations on the resolutions/focal distance, everything was converted to 2560x1440.

Choose "2.5K 2520x1418" mode and select 16:9. That's all.

dah...right in front of me. Thanks

Quote from: Danne on June 22, 2020, 02:24:01 PM
Don+´t touch those settings at all. Should be at max.

Thanks Danne!

There are 2 different 2.5K modes. One brings 1920x1080, the other 2192x1234 for 16:9 ratio.

How do i get the 2192x1234? i must be doing something wrong.

Here's the second part...same place...same settings... on a sidenote i'm starting to slowly using more and more Davinci Resolve, i use Premiere Pro and i find it very intuitive and easy to use/colorgrade/edit and been trying to do the same edits with both programs and Resolve can handle the exported prores/cdng way better than Premiere, a lot of playback stutter and previewing effects with Premiere whilst in Resolve everything is alot smoother and its free.
