Share Your Videos / 5D3 1080 3x3 unleashed
« on: September 19, 2021, 05:39:00 PM »
The new debayering algorithm in resolve 17 works wonders with 5D3 3x3 footage!
It's so great that I no longer use other modes.
Real time correct preview is another treat!
Everyone with a 5D3 needs to try this.  I hope someday mlvapp will be able to debayer this well!
Seriously, this is a whole new lease on life for the 5D3.  I wonder if the 5D4 has a similar 3x3 mode?  Imagine what it could do with that improved sensor...

I wasn't 100% convinced that DWG was beneficial for SDR video, so I shot this extremely challenging scene and it really makes a difference!
When the clouds roll in, it stays beautiful.  This is static processing: one setting for the entire scene!

Hi everyone,
I was lurking and saw this discussion so I dusted off my 5d3 and shot this little clip using the anamorphic mode, converted to dng using mlvapp, and then stretched and graded in resolve.
I specifically wore the patterned shirt to stress test for moire, and it seems not bad, but if you look closely at my shorts you may notice vertical stripes that shouldn't be there!
But it is pretty subtle.
It's such a treat to have full frame recording.  It makes my 35mm T1.5 really look great!

yes, i had the same experience on a few occasions.  it stopped me from using mlvfs...

It's a setup for the 5d3 made by timbytheriver and myself that facilitates optimising the gains on the camera to improve dynamic range and reduce noise in the shadows, especially chroma noise.

A1ex discovered the registers many years ago but development stopped quickly afterward.  It has since become taboo in this community, but if you search the forum you can find information if you are interested.

The long and the short of it:
If you carefully calibrate your camera, you can gain close to 1 stop of usable dynamic range, which is important to some of us.  It is not supported and there is no cooperation from anyone here.  Quite the opposite.

Everything you need to know is searchable.  I made a couple of tutorial videos some time ago.

It is only useful to anyone who is wanting to push their camera right to the limit.  For "typical" users it is probably not useful.  A possible barometer of applicability would be if you use a hardware tool to calibrate your monitor, and if you can see the details of my shirt in the video above.

With the talk about youtube performance, I thought I would give it a serious test using TNT at 1440p:

I shot this at 2560*1440 (14 bit using TNT) and graded it in resolve to put all it's got into the darks.

Watch it in a dark room on a good screen at 1440p!  Look closely at all the textures and detail of my black shirt under the coat.

As always, no noise reduction of any kind.  TNT at its best!

if it wasn't for the subtle vertical stripes noise in the bright midtones (such as piano keys) I would call this perfect looking...

would it be possible to add the ability to remove jobs from the render list while rendering is underway?

when i am doing batch renders, splitting the jobs across multiple instances of mlvapp, invariably some finish earlier than others, and it would be nice to be able to have them take on clips from other instances without having the other one potentially redoing clips that were reassigned to other instances.

actually, i think that canon did the right thing (within the bounds of their obvious marketing requirements of making it noncompetitive with their cinema line).

they wanted a camera that can be used only by amateurs for video while being as high quality as possible, and they achieved it.

the timer based thermal regulation makes a lot of sense if you think about it from a manufacturer's perspective:

the internal temperatures are getting dangerously high during demanding tasks like 8k recording, and they are not sufficiently regulating this, so they are shutting down before instant damage occurs.  but the other danger is long term damage from constantly cycling between overheated and cool conditions, especially for "cold solder" development, or even cracked circuit boards.

so they used intentionally "misapplied" thermal tape to actually slow the dissipation and employed a timer that won't allow the user to generate those dangerous temperatures again for 2 hours.  this way it slowly cools either to a safer operating temperature or completely to ambient temperature, depending on whether it is shut down completely or re-engaged after 20 minutes for photography only.  this was a wise setup within the restriction of being a consumer use only camera.  they should have been more upfront about it however to prevent the conspiracy theories (which were partially correct, but not taking into account the longevity factor listed above).  they underestimated the intelligence of the user to be able to understand their rationale, and in doing so have harmed their reputation for years to come.

and to make matters worse, they pushed out that firmware "upgrade" that reduced the timer values, which will almost certainly shorten the lifespan of the camera.

but their accountants probably decided it was better to appease the ignorant masses and sell more cameras even if they will be facing a lot of problems in a few years...  probably looks better on their balance sheet.  let's face it, they are probably counting on exiting the consumer camera space by then anyways thanks to cellphones as cameras...

so this hardware mod is an excellent idea in conjunction with proper thermal monitoring to ensure the camera is not being operated at dangerously high temperatures, which should have been done properly in the first place, regardless of marketing ideology.  it seems likely to me that the code is already in there, just not exposed to anyone but canon service personnel (for now!)

windows resolve users can now work with card spanning straight from the cards!

i combined the "lossless" version of mlvfs.exe with a newer version of dokan, and packaged it with my little batch file for "linking" 2 cards into one virtual drive, and added a readme file to provide step-by-step instructions.

once you are set up, you can take your 2 cards out of your 5d3, put them into your card reader, and resolve is ready to rock!

thank you for the kind words, a very rare experience for me on this forum...

i think the main issue with people is apathy.  they simply don't realize that the actions of individuals DO count.

you don't have to be a crazy retired music producer with your own forest to do significant things, although it is a great experience to live here and witness the beauty and intricate balance of nature as well as the results of my efforts.

the destruction of habitat for industrial farming is rampant here also.  one thing nobody mentions is that the vast majority of factory farmland and gmo crops are for animal feed.

it's great that you mentioned the bees and insects.  something happened here recently where the farmer beside my forest sprayed his field with glyphosate in september, a field that was growing fallow for the year to recover from 5 years of growing toxic ginseng.  the field was packed full of wildflowers when he sprayed, and it wiped out ALL of the butterflies and 95% of the bees.

i made an episode of one of my video series about it, and a trilogy of songs, the first of which was a collaboration with timbytheriver!

please share it with your friends who understand and maybe they can share it too...  the word needs to spread!

wow, that is really great!
those are some nice mushrooms...  it reminds me of when i visited back home in 1980 in the mountains of yugoslavia...

thanks for the beautiful video.

it's amazing what that little camera can do in the right hands ;)

thanks ida :)

i do everything myself.  i wish i had a production partner!  only one camera, and since i'm in the studio recording the parts, i just film myself performing.  i don't do any remote start/stop, i just record everything and trim in mlvapp while exporting the dng sequences.

timbytheriver turned me onto a nice pair of plugins by the bald avenger for resolve, and i'm over the moon with how great they are! "film grade" and "soft clip".

i used them on the latest ttt episode.  "grading" was almost effortless and i love how it turned out!

@christian, i'm sorry i don't know.  i only shoot at 23.976 or 18fps.  try it and let us know!

is there anyone out there who is willing/able to port the mlv_dump code to mlv app?

« on: October 25, 2020, 02:20:42 PM »
that's great!  no flickering :)

i wish i had used such steps back when i did this footage.  i had used barracudaGUI and obviously something doesn't work there.  also mlvapp was/is the same.  i just tried it again with the latest version and it still flickers.

maybe they could look at your procedure and make sure they are doing it properly...

it's a shame i no longer have the source for that video.  i would reprocess it using your steps!

BTW: in this scene the camera is tilting from the forest floor to the sky.  it gets a LOT brighter :P

thanks for the info, hopefully it gets put to use!

the original mlv is long gone, so i cannot say for certain about any bit depth reduction on that file, but i gave dual iso another shot 2 months ago in one of my music videos and the problem was still there, and it was definitely 14 bit.  in this scene, i'm playing a synth in the studio, and the reflective highlights on the control knobs make the image flicker when i move around and block the reflections...

in another shot, pulsing LEDs on a synth made the image flicker.

it's not difficult to reproduce this issue.  just have a scene with wide dynamic range and a single light source (the kind you would be using dual iso to capture!) and see how the image changes when you block the light.

walking in front of a light bulb would work.

the attachment i provided in the original issue reported (and linked above by sm105) is still valid...

i'm only responding now, so late, because someone else made reference to this thread recently:

the scene was not underexposed.

this is only a portion of a motion picture scene, one in which the lighting changes, as is apt to happen in MOTION pictures.

it was indeed exposed to the right, for a different part of the same scene not included in the tiny attachment.

the flickering issue persists to this day and it is not a corner case.  it happens whenever there is changing light during a scene that crosses the line between the two exposures.

it remains a showstopper for dual iso in real cinematic use.

it's a good thing i was finished my drink before i opened your thread... i would have done a spit take when i laughed!

thanks for the laugh ;)

the race to the bottom...
