here's those frames:

the frame with the sunlit cut log showcases how well mlvapp handles highlight reconstruction when only one channel is clipped.  i intentionally clipped the red channel on this shot to get enough of the dark scene at the beginning of the shot.

all that is required to correct it in mlvapp is to enable highlight reconstruction and then pull back the highlights just enough to get red of the clipping on the red channel in the histogram, and suddenly you can see the nice detail in the sunlit surface of the cut log, with no pink highlights.

it was a lot harder to do this in resolve!

with the renewed debate about 3k, i decided to shoot my latest forest video in 3k, utilizing resolve's superscaling algorithm to bring it up to 4k using 4X upscaling:

must view at 4k to see it correctly!  check out the incredible smoothness of the razor sharp spider webs that are clipping in the sunlight...

ps: i'll send some frames to ml700d

my internet connection is quite slow here in the forest so i can send you some frames if that is ok for you?
it sometimes takes a day to upload a compressed hevc to youtube...

I used resolve for grading.  i use MLVFS for instant grading.  put the card into the reader, and a few clicks later it's ready to edit and grade!  Outputting to NV-HEVC is ridiculously fast.  in this case, from camera to uploading graded video in a few minutes...

the lens used is sigma 105mm F/2.8 IS.
300mm focal distance for 1:1

focal length was 12 inches.

i actually like a bit of movement when doing a focus pull, plus the branches are moving in the wind...

most of all, i'm just too lazy to do software stabilization!  :P

IS was a lifesaver for a handheld focus pull at maximum closeup on the tiny redwood bud!

watch in 4k to bypass youtube quality degradation...

Everything's beautiful when filmed with magic lantern!

Thanks to you wonderful people for all you do:  keeping these old cameras going...

The winter that wasn't...

Long point, Ontario - February 20, 2023
View in 4K for original quality.

update (feb 2023) : Dokan version is recommended

mine is

i hope that fixes it for you... fingers crossed!

I am using win10x64 with mlvfs and it is rock solid.  i have it packaged in the file i linked in the opening post of this thread:

are we getting close to a new mlv app official version?
i'd like to try it again comparing to resolve, and any extra speed for the windows version would be most welcomed!

the story continues...
on valentine's day the latest handful of chestnuts comes out of the refrigerator to start growing more trees!
i'll make a video about it.
there's a playlist on my channel called "the american chestnut" with more information about what's happening with my labour of love!

for dual iso in such an extreme situation the best results would probably be from a more extreme setting such as 100/1600...

but don't expect miracles from an unlit enclosed space and daylit scenery through a small window.  try adding very soft lighting to the room and a subtle key light to the subject to keep the "unlit" look and adjust the grading accordingly.

that will help more than anything else!

i really don't know...
once you see what i'm doing, you should try to reproduce it with your camera and hopefully it will become self-evident.  i'm optimising for resolve, and some of my camera workflow might be only possible on 5d3 at this time unless you can reproduce the setup on your 700d.  it still may "just work" (only for reducing pink sunspots)  if you follow the rest of the steps without the specific 5d3-only register settings.

it will make sense when you see the "how-to" video!

thank you!

by the way, i'm doing some new tests to try to completely eliminate the "pink sun" effect while filming.  in my latest video, i have the setting sun in the shot, behind my back, with no lights or reflectors, and i'm in the shadow of a huge tree!  now that is serious dynamic range! :)

so far, i've managed to get it down to just a few pixels, but i'm hoping to get it down to zero!

i'll be posting a video about this very soon, but i won't be sharing it on here.  anyone interested to see how i do it should subscribe to my channel...

peace to everyone!

I forgot to mention, watch the video in 4k!!

i'm a little late to the 5d3 240mhz party, but here's my results!
in case the image doesn't work, it's 96 MB/S  :)

there's more than one answer to the challenge of shooting in low light  ;)

sometimes you want as much dynamic range as possible, even in very dim light, and with the 5d3 that means iso 200...

check out the beautiful detail on the LEDs in a nearly dark room, with the shadows severely lifted in post.

shot in 3616*1536 continuous (thanks bilal!), and upscaled to 3840 using sinc algorithm in resolve.

watch in 4k to avoid the horrible quality degradation of youtube imposed on videos with <3000 views.

best wishes to everyone!

Academic Corner / interesting image compression!

seriously dim lighting except the vocal booth, which unfortunately was a little too bright!

excellent news!
regarding the 5d3, was any testing done to determine if the maximum recording bitrate using card spanning and overclock increases beyond the "limit" we found when overclocking to 160MHz?

I'm now making the occasional Blender3D tutorial video.  This one (the second in the series) covers workarounds for the "eccentric" rigid body simulation to make a chain that doesn't break:

A short but sweet exploration of the forest in early morning.  The extreme dynamic range isn't even apparent in the resulting video because it was so easily controlled!
Every shot has both clipped highlights and lifted shadows, sometimes by many stops (such as the closeup of the chestnut tree bark).
Watch in 4k!

Get a manual aperture lens.  Rokinon cine lenses are really good and very affordable!  Set it and forget it!
