Everything online says to double the shutter speed to the frame rate......

is that not the case then?

So I need to match the shutter speed to the playback speed 1:1 (ie shooting 50fps to playback at 25fps means 1/50th shutter speed?)

well that’s confusing ....

I find the footage is not smooth and it jutters......

the shoe clip begins with normal speed and then when the frame goes smaller it’s the 50% slower and then back to normal 

I’ve included the clips in normal speed to see the difference

I don’t understand the settings I need to have to get a nice 50fps to 25fps playback (shutter speed-wise)

...it looks shit to me...

is there a way to fix this in post?

Hmmm

what do u think this might mean?

I’m viewing this on my MacBook in the UK

I’m  showing it to other people and they notice it too....

Strange 

is it the high shutter speed causing this crispness

i was on 1/100th with 50fps.... I think the project rate is 50fps for FS5 and that makes it look like this....

I'm used to the Amira where i can set my project rate to 25fps and get the smooth playback.

I'll have to be reaaaallly careful with editing 

no i'm talking about the judder...

oh i think i've just made a huge mistake.... not sure why this is though....

FS5 is not my preferable camera. 

helppppppp

Hello!

I'm shooting a fashion film with an FS5 and I'm trying to shoot in 50fps so I can slow it down later in post. 

My settings are at 1920X1080 50fps but the playback in a 25fps sequence in Premiere (and changing the speed of the clip) is juddering. 

I'm not sure why. I got my shutter speed at 100 - What am i doing wrong|?

File Format: XAVC HD
REC FORMAT: 1080/50p 50Mbps

Short example below

What am i doing wrong? 

It's far more noticable when moving more 

Got it

So, 

Single Frame: adapting the meter to 25fps (so essentially no change!)
and for 

for 50fps adapting the meter to 70fps!

Thank you!!

Thank you!

Does this mean that I should rate the 25fps shooting mode (1/70) by setting my meter to 32 or 36 f/s (it doesn't have the option of 35)

?

This is kind of a new twist!

According to the manual:

 "Exposures Real" + "Photometric" stats for Single frame is the same as 18FPS

Would you say it's safe to measure according to this?

A

Thank you!

My meter goes down to 2f/s, not one. Not sure why that is...

I'm planning on doing one frame at a time. Not continuous 

I'll check with the manual on the shutter speed of the electric bolex

1 hour ago, Uli Meyer said:

Overexposing one stop is fine. I tend to meter with the correct ISO and open up the aperture a little, not necessarily always a full stop.

OK, noted! Why is that? 

Hello there. 

Thank you for your reply ?

So, my plan is to shoot the single frame and slow motion and get it developed and transferred to 25fps. 

The reason i'm wondering is whether whilst shooting it might need another setting (for example, I will change the 25f/s to 50f/s)

Not sure about the single frame and whether that will need any changes in the light meter. 

Yes, I have the ISO set to 200. I was told to overexpose the film a little bit.... Do you have another opinion?

Happy to hear about it!

Hello there!

Attaching my light meter and how is set when I shoot 250D 16mm on an Electric Bolex. 

I want to do single frame shooting and 50fps in my upcoming shoot. 

How should these different modes affect my meter?

Many thanks!

Hello there. 

Before I upload a new grade, I think it might be useful to share my setup up

Sharing the sRGB EIZO monitor setup
and some information on the colour specs in Da Vinci... 

For now, I'm working only for an online prores/h264 export. 
 

Hello and thank you for the replies!

In case I confused you, just to mention again that when I graded this, I was only using my Macbook screen.
I don't have the Resolve settings in front of me but I can supply soonest possible!

The vimeo (H264 export) link https://vimeo.com/457743955 (password: wednesday) is the export that I used for the DCP projection
For the DCP I was asked to export a Quicktime, JPEG200, 2k DCI Flat, 250mb/s

Now, for the new grade
Currently, the settings of my EIZO monitor -  attached in the image
I can send you the sRGB settings as well tomorrow....

Regarding noise:
I have a full version of resolve... you mean the motion effects?
hmmm... i always think it softens the image a bit too much. Perhaps i just need to explore. 

Hey Daniel!

Thanks for this!

I had no idea

I have the studio version and will look into it when I commence the grade all over again!

Thank you Phil. 

It's really helpful to just a get reading from someone else. 

Yes, this last one you sent over with the histogram is def easier to manage (there was a home daylight lamp in the room so it's kind of ok, no orange tint --and  the Cinelab technical grade in the transcodes is actually quite lovely. 

It's the (terminal) error of not using the lamp on all shoot dates that I'm struggling with but from what i'm getting, I should relax my expectations and try and do my best with it. 

I'm learning in the most silly way !! 

a

I know ?

I really don't have an excuse. it was a stupid idea not to get the light on all shoot days...

Also, is there a tutorial video that deals with these issues taking into account 16mm film footage? 

MANY THANKS!

Thank you Phil!

I see what you are suggesting there! 

It's close to where I would push it as well. How would you describe what you did there? Is it tint and colour temperature (to put it roughly)

The other detail of this project is as follows...
I made some footage using the 250d and a daylight involved so I did get some footage that look decent.
I have a feeling the orange footage will never come close to this though...

What do you think?

Hi guys!

I hope everyone is holding up ok. 

Grading nightmare below:

I've shot a film with 250d and 500t rolls and in some cases (when using the 250d indoors and in low light) I got a orange tinted result (raw scan images attached)
Now, I'm planning on grading this in da vinci. I'm not so sure I can do a massively good job because I've tried a few times and I always get up to a point where the image look ok but still not balanced enough to make me see past the grade (it looks very pushed)

Have a look at these two screenshots... are they salvageable in your eyes?

A

Hi guys!

Firstly, 

Thank you Stephen for having a look :) 

I'm now in the process of grading another film a friend shot. And then two more....

This next one is 40 mins so It's quite long and I made the mistake of telling her to get LOG scans from the lab. I think the 'best light' option is the best way forward...no? I find that Cinelab does a grand job with their in house grades...

I know it's supposed to be more versatile to get LOG scans but i'm NOT a grader so I am again finding it a bit tricky.

Better than last time though. 

Are there any online helpful tips for 16mm grading? I can't seem to find anything------ only how to emulate the film look on digital. 

My main concern is that I want the images to have LIGHT and BRIGHTNESS! Contrast and Depth without crashing blacks or blowing up whites. But, when I do try that, then the grain becomes so alive and I can see it moving everywhere... is that how it should look? Or do I need to apply a noise reduction (and if so, which one?)

I'm attaching two screenshots..... i'm trying to make a basic grade but i still feel that it's yellowish and has that LOG scan feel to it... what do you think?

OH GOD

any tips?

many many thanks!

A

Hi guys, 

Glad I found this now, 

Sorry i didn't look before i shot a project in 50fps to edit in 25fps with the Mini Alexa. 

I'm getting this mild short shutter speed look and the director is not liking it

I've tried a few things

Adjusting clip speed (using optical interpolation when it's not too heavy movement)

I've made a 50fps sequence and this works the best but the post house won't work with this

I've also re-interpreted the footage but without a lot of progress either. Maybe slightly better though. 

Do you have any other ideas?

THANK YOU

A

Thank you to everyone!

i think I should start grading some 2K scans.. it does take an aggressive punch to get it to a good point. And I hear you re: grain. It’s in the film DNA. I didn’t know the labs reduce grain.... is this an “industry” standard? Funny...

for this occasion it would have been impossible to learn to grade log, as it’s an almost 5 minute music video that needs to finish in a couple of weeks. 

So, for this one I used the HD prores uncompressed (best light) files. Graded in davinci mostly but also some in premier with lumetri.

i liked what the lab did with them, but then I moved on from there to create a world that makes sense with my aesthetic intentions.

It still needs some work on the night shots but the whole film should be regarded within the excitement of using 16mm (with its light spills, bad focus, x-ray damage!) an image that breathes ? Latent image, what a pleasure!!
