frame rate problem, grey line problem 5d3raw

[anandkamal]

friends, i shot some footage with ML (feb 14 update, nightly build) 5d mk III. I set the frame rate to 23.976 while shooting and it shows so in the raw2cdng software correctly. In resolve10, it shows 24fps and even after changing the master project settings, the rendered out clips are 24fps. I also found this when i imported the clips to premiere pro cc 7.2.1. May be because of this change in frame rate, the rendered clips and clips inside premiere show grey lines on the top of some frames like below. Or might the setting of frame rate and aspect ratio be wrongly done while shooting? help me out... pls.. next week i have a commitment.. thanks.

Wich camera settings have you put? Aperture, ISO and most important for my opinion, exposition.

Put the blacks down and export to pro res.

It's visible the problem?

And double check the project settings in Da Vinci - I left premiere, it's a problem for me.

i often use iso 2500 ML, 6400 canon, -1.5ev... for night shots.... and iso 25-100 for day shots... shutter speed often to 1/50 (bcos my frame rate is 23.976).

I use windows, so i export the intermediary files using quicktime mpeg4 or quicktime h264 for roundtrip. I once got this issue and learned that aspect ratio needs to be set correctly. The problem was then cleared. It now reappears despite the frame rate and aspect ratio settings corrected.

while i shoot, it shows like the footage is shooting at 23.976 in camera's display. Also, raw2cdng shows the same 23.98 fps. But resolve shows the frame rate to be 24. How to set 23.976 in 5d mark iii under magic lantern menu?

[budafilms]

Maybe some kind of light are not working fine at 1/50. The iso is too high. For my opinion, use more real values, like 1600 analog.
Try to put blacks more down, and reduce banding.
Maybe you can apply an estethic filter to save some shoot.

You can set Da Vinci - check last update in the site - to 23,98! And you can set the export to the same.

I decide to shoot always at 24 in the canon Menu. Are you gong to put the shoot for telecine? If not, use 24 Ntsc or 25 in Pal.

[anandkamal]

hi I set the resolve settings to 23.98 and exported through 23.98. I still get the flickering grey line at the top in rendered output and consequently in premiere. I am using magic lantern raw for an independent cine project. I also set frames per second to 24 in canon menu. 1) can I set fps in magic lantern menu? 2) Why is resolve and premiere showing me the fps to be 24 when I shoot at 23.976 as this may affect the roundtrip?

Try this to check your camera: rec h264 with out ML card if the grey persist its a big problem. If not,  download other version of ML, format the card and try again with the same setting. If persist change the card and get out the battery for ten seconds.

1)You can set fps override in ML
2) Maybe you have 24 fps override in ML, that's could be a reason.

i shot without ML card.. recorded in h264. I directly played the h264, no problem. I imported to premiere pro and exported the media, no problem. I imported the h264 to Resolve and exported, there were grey lines at the top of some frames when played. This carried to premiere when i imported those files. So, nothing wrong with ML, but with davinci resolve.. am i right? How can i rectify this? reinstall resolve?

[budafilms]

of course, but...... delete the preferences, and create a total new project!

could be your video card! I'm not good with PC, I use Mac, I know that da vinci use CUDAS - i think premiere too - maybe you have to upgrade drivers... i don't know your configuration, but Da Vinci is hungry of video card.

[anandkamal]

i am working with 3gb geforce gtx 780, 32gb ram, i7 4770 3.5gz... i think this will be ok for davinci. I will update the grey line problem after reinstalling resolve and creating a new project thanks.. Also, even after i set 23.976 in ML and canon, premiere pro and resolve shows it to be 24fps. This problem persists. I don't know why. Is this because the cdngs are image sequences and there can be no decimals, so rounding it to 24??

[budafilms]

I don't haven a technical  answer about decimal staff. Maybe a Dev.
My suggestion for next shoots are use 24.
Used your footage at 24! The audio could be adjusted easily in that differences!

[anandkamal]

I could not shoot at 24, because this being an independent cine project. I should shoot at 23.976 so that it would be compatible while converting the footages for Digital Cinema Package (DCP). I just would like to know if others are also facing the same problem (resolve and premiere showing 24fps even after shooting with 23.976)?? so that i will know my camera settings is wrong. Thanks.

I do that! You can edit all your footage, and in the final output to DCP, you can export video and audio in image sequences at 23,98. The differences it's imposible to perceive. Even, the people how works in Post Production can do that with the image sequences.

Try with a short edit to probe it.

You can do either a round trip from DaVinci, to Premiere (I hate Premiere) and Resolve to do the last output. You can work with very low resolution. You should have all your footage in the same folder.

Good movie!

When you set your camera in ML menu at 23.976 it is recording 23.976.

Raw DNGs don't hold fps metadata properly in resolve once you click your default untitled project after log in/ right click it to confirm in master setting that fps is at 23.976.
Once you import your DNG into the bin its now 23.976. If you just click the preset, and not change it in master settings your dng clip will be marked as 24 and you have to go to clip attributes and change manually the clip speed.

[anandkamal]

i changed the master project settings, export and other render settings to 23.976. Now i don't mind resolve or premiere showing me 24fps. But i still get the grey line at the top of some frames in clips. I heard somewhere that resolve's default is 1920x1088 and since we record at 1920x1080, it shows so... I can only correct it by adding a letterbox, or by changing the viewing format to 2.35:1 aspect ratio. New problem is that i get whole clips flickering (graded and ungraded) after I do color correction manually. I don't see this when applied LUT. Why would that be? how can i correct it? thanks
