Share Your Videos / EOS 50D Walklapse
« on: January 25, 2015, 02:34:53 PM »
I was experimenting with some walklapse shots mixed with static timelapses. Mostly shot in raw using the normal TL function in ML. Some shots are done in JPEG using the technicolor PP. Stabilized with AE warp stabilizer.

a few months ago i posted a film called synthlapse based on mirrored timelapse shots from the 50D.
at the end it promised a second part.
so be sure to watch synthlapse first!

i got a bit carried away after seeing gravity.
so i added a few space scenes. and some explosions. and hostile space craft. and tanks. and gas masks....

obviously all not completely shot in camera with the 50D...  ;) so, i hope this is okay.
chromakeying was a charm in the window shot. the shot compromises the fluidity of the final edit a little bit, but i left it because it was fun to do it.

one long term timelapse shot was taken with a rollei 4s action cam. i used the fish eye distortion in these jpeg sequences to simulate a slight camera movement.

the final short is more a result of warming up of some old skills and a lot of experimentation and optimizing workflows for myself.
and a small showreel with kind of a story  :D

have fun!

hi guys!
good to see still movement in the develepment and some final touches.
got some new footage. haven´t changed ML on my cards for months. it just works ;-)
aliasing in the last shot is horrible. but, nothing is perfect...

shot with sigma apo 70-200 mm 2.8 (crop mode up to 600mm. that´s why it´s sometimes a little shaky) and canon 28 mm 2.8

here´s another video....all is shot on the 50D, mostly with 10 to 12 fps.
still better, than just lamp posts ;-)

i tried, to bring a narrative component to good old timelapse. enjoy:

another combination of timelapse, mirroring and this time a little bit cgi
shot on the 50D with mostly 10-12 fps and 3:2 ratio. i did no upscale to maintain the image aspect.

The RAW files were converted to dng sequences with Rawanizer ver 0.5.5. DNxHD proxies were used to edit the footage in Adobe Premiere CC. Once edited, the sequence was brought into Adobe After Effects CC via Dynamic Link and the proxies were replaced with the RAW footage. First light color correction was done in ACR, and additional corrections were performed in AE. All compositing was performed within AE.  Gorilla Grain was added to the final output.

this is exactly the workflow i´m using now too.
first i saved the proxies by importing the dng´s straight into premiere. but the ginger plug in only works for 30 days for free....
but i´m using then EXR files in after effects and set the dnxhd files as proxy files. this can help with slower computers. for me it is the same speed.

i wrote a step by step guide on using this method. but it is outdated because of the ginger plug in issue and the slow dng performance.

what i noticed is, albeit using 32 bit floating point EXR files it is still crucial to "develop" the dngs in ACR correctly. trying to tune the exposure with colorista sort of works, but comes not even close to the exposure control possible with ACR.

i use the EXR sequences, because they process roughly 400 to 600 percent faster (depending on filters, masks, layering....etc). reducing rendertime (for my last 4 minute clip) from nearly 18 h to 6 h....
and i can use the sequences in my favourite comp software: nuke. nuke is highly optimized for 32 bit EXRs.

and yes, working in raw is a real pain.

if you plan just to edit your footage and then grade it in AE. you can stick with the dng workflow. you replace the footage, grade, adjust....hit the render button and go to bed... you can even save rendertime by adding more than one output file format in AEs render queue per comp. ( image sequence + your proxy format )
AE compositions can be rendered in the media encoder offering a much broader output file format (AE does h264 but you can´t adjust the settings.... or i am just blind...)

if you plan to add a lot of compositing to your images, then the EXR workflow is your first choice. ( or tiffs, if you wish )

the RAW dng sequences can be zipped, reducing disk space by about 25%.

what are your strategies for archiving?

i plan to save the uncut clips as dnxhd 10bit
and one consolidated AE project with only the used dngs, to reduce data amount and then zipping it in one archive file.

ah yes and the above mentioned "filmconverter" is a AE plug in, that adds not only film stock specific color tone and exposure response, but also the corresponding grain. within it you can choose different film sizes ( from 8 mm to 35 mm full frame ). this setting influences the grain size dramatically. never go under super 16 mm.

you don´t really need such filters. the grain from the 50d files is very filmic and the special film stock looks can be achieved by simple color correction and a little bit channel blurring and maybe a glow.....

some pretty extreme grading:

filmed entirely on the 50D. mirrored, graded and some filters on top...

still trying to get a freeware workflow. this is done @work using creative suite and saphire plug ins.
(after effects+acr+scaling => dnxhd proxies/EXR sequences, edited in premiere with dnxhd proxies. sequence replaced with after effects composition. footage replaced with EXR sequences => grading+FX)

this is my first video not only for testing.

i experimented a little bit with mirroring my timelapse footage and somehow got lost with it....
now after just under 24 hours from shooting to upload.
there it is!

as expected, the youtube compression steals a lot of detail. the original EXR master is completely flawless of banding or artifacts and represents all the information in the original dng files. well.... i just don´t trust TIFFs    ;)

the noise is really great! i love the 50D.
magic lantern makes me feel like 12 again, making my first short movie....since then dreaming of a consumer reachable camera, that gives me exact these capabilities.

Thank You!

i´m striving through the raw therapee forum.
they have really good attempts on integrating some kind of video (aimed at timelapse purposes) functionality.

really good ideas on gpu acceleration, open exr integration (oexr is a rock solid, free image format....whereas tiff is just a container format and can be everything, making it somewhat dangerous to work with) , debayering methods.... and so on.

what i understand in that forum, they really need people to code. just raw man power.

for me the raw recording function and dng extraction works stable and i would use it as a real world production workflow.
now that the first step is done, it would be a really great opportunity to keep magic lantern raw recording really open source and independent.

depending on black magic and hoping they implement and support the #1 pocket cinema killer..... well, it works somehow. but depending on the good will of a profit oriented firm could be the wrong idea.

the adobe way is not free and nobody knows what will happen next in the adobe cloud.

developing a true ML own workflow would be perfect. inventing the wheel from scratch, while there´s a great free tool.... it just feels wrong  ;)

but a cooperation with the raw therapee folks could be the best short cut to a true open source consistent and big name independent raw system.

because: raw means your image is finally created in post

hi andy!

i think your guide will be awesome.
if you need any help with it or want some more eyes to take a look at it, i would be glad to do so.

i´m in the tv, film and commercial business since 12 years and the last 5 years i worked as a technical director, trained hundreds of people and wrote many manuals and optimized workflow after workflow.

and maybe just somebody wants a german translation..... just tell me ;-)

back again. found some time to test 50Ds low light capabilities.   see video description for details.

i´m also refining my post workflow (see: )
for your moiré needs with ACR see:

i also tested rawtherapee  a few weeks ago. the different debayering methods are amazing. the tone mapping function is also very interesting.
but it is very slooooow and crashes from time to time.
rawtherapee+gpu raw encoding would be great.... and they´re working on it!

Raw Video / Re: Real 12 bit uncompressed post workflow
« on: June 25, 2013, 09:21:35 PM »
the danger with premiere itself is, it fools you sometimes by taking anything and then causing trouble over time.
i know this because i serviced some premiere suites for a few years and there was always trouble.

i always suggest to use edius.
it´s no hip or funky software, but it is stable as hell. the color corrector is rubbish...but would be good enough to edit, generate a edl and go to resolve. it also has a after effects plug ins interface, but ginger plug in is not supported.

anybody knows a way of getting cdngs into avid straight??

okay, didn´t test floating tiffs.
just tried the 16 bit ones and premiere refused them.

and tiffs can always be dangerous because there´s no real standard. tiffs can be anything....

and blowing up 14 bit files to 32 bit float was not what i had in mind by finding a workflow that involves the only transcoding process at the end.
the only other solution is to edit in resolve.

i will send that project to resolve. render it out and start a comparison.

It's only an 8GB card which I'm using as a quick test before forking out for a bigger card. Would this make a difference? Thanks

yes, it makes a big difference. i tested the 16 GB x800 card and couldn´t get higher writing speeds than 40 MB/s.
changed to komputerbay 32 GB x1000 and now the 80 MB/s are no problem!!

i think the 8 GB card is even slower than the 16 GB. this cards may have a udma7 interface but they are slower on the inside so to speak.

i recommend you buy a komputerbay card. but only the x1000s

here´s some test footage including nearly almost wide shots. did not check all shots for moire.
but some are corrected via ACR moire reduction.

can´t upload to vimeo atm, so there´s just a 720p youtube version. original resolution is 1536x1056 and much cleaner and sharper.
did some upscale/downscale tricks to reduce line aliasing. pretty subtle. but the dark outlines of the buildings are nearly straight.

lens: canon 28mm 2.8 prime
workflow: as described in my 12 bit workflow post (very slow, but the final product is a robust 32bit exr sequence that renders to every format very fast)

updated to 1080p:

Raw Video / 14 bit h264 video possible?
« on: June 25, 2013, 06:04:45 PM »
tonight i had a pretty weird idea and i´m already researching h264 in detail and also found some software to extract motion vectors from h264

h264 is a interframe codec. based on I-frames (intra frames, still images) which act as color and luminance source and P- and B-frames which contain pixel associated motion vectors. based on this information the decoder recreates a moving image.

the idea is based on the question if it is possible to record the live view image as a normal h264 stream and at the same time record raw images at a rate of maybe 6-8 frames a second.

now take the h264 video as a motion source and the single dngs as a "image content" source.
so the same way twixtor or any other motion vector based software interpolates inbetween images, this could - at least in theory - be a way to recreate a 14 bit video based on h264 and raw recording.
no need to create motion vectors, they are already recorded.

but the key would be the possibility to record h264 and raw simultaneously.... so i ask you: is this possible?

could be a way to get rid of memory bottlenecks.
upscaled motion information could be sufficient enough to make your 6 fps high res images play back smoothly @ 24 fps....

this is just an idea of making some kind of compressed raw available.

Is it even worth the development effort, to use a small fraction of the 50D sensor (effectively turning 50D into a tiny sensor, consumer level camcorder), RAW or not? (I am talking about zoom RAW recording.) With a tiny sensor, you lose most of the advantages of the DSLR-based video-camera - shallow DoF and great light sensitivity.

of course it is!

in crop mode you get a 1:1 pixel representation. yeah, it is just a pretty tiny fraction of the sensor size. but it´s fine for establishing shots or high detail images.
from a technical point of view there should be no difference in dynamic range or sensitivity. just noise could be a little bit more noticeable.

for your shallow dop needs you can use the non crop resolutions. faces or close ups of organic things without sharp edges work perfectly.
to avoid aliasing in sound recorded with low sampling frequency ( to record a frequency range between 20 hz and 20 khz the sampling frequency has to be 40 khz according to shannon-nyquist)

there´s something called noise shaping. maybe turning the iso levels up to generate a strong random noise pattern could help prevent edge aliasing.
could be a reason why some people report moire reduction after applying noise reduction.

this method can also be used to avoid bending in your web videos: just ad a little amount of noise to your videos.
the encoder (mostly h264) detects the noise as detail and lowers its macroblocking giving smoother gradients in large flat surfaces (skies etc.)

the magical images from the 50D are in my opinion a result of the "low" resolution chip. a 50D with a 10 or 12 MP sensor would give you even better images. the 50D was called a pixel over kill when it was released. if they built in a lower res sensor with bigger sensel size dynamic and low light performance could even be better. but the 50Ds sensor was quite unique at that time. the first one without real spaces between the sensels.
and if i understand the live view down scale line skipping right, there would be less line aliasing as a result of less lines needed to be skipped.

is this correct?

so theoretically the 40D would give better line-aliasing results.
moire can only be solved in cam with an optical low pass filter since the visible moire effect is just a result of the nyquist-shannon theoreme. every image sensor has its high frequency limits (high frequencies meaning small image details).

a lower res chip can be the solution for micro moire.

an ideal cam would have a full frame 35 mm faveon (or 3 chip) style sensor with the exact pixel count you want to shoot and a specially designed LPF.

this is the reason why the 5DIII is so good for video: good LPF and a sensor pixel count that´s ideal for downscaling.

did some tests with the moire reduction in ACR. works pretty good in special cases!

« on: June 25, 2013, 03:31:48 AM »
For all of you using ACR:

for static images you can paint out moire/aliasing. apply a mask in ACR paint over the moire/aliasing infected areas (fine building structures etc.) and find the slider named "moire reduction". depending on the amount of moire apply a value of about 20 to 30 (+/-). use it carefully since it seems to blur the affected color channels and you loose a lot of saturation but not contrast, giving you a sharper yet less aliased image.

for moving images or moire all over the image just set a big paint stroke over the whole image and adjust as desired.
the effect is stunning. but you lose of course a lot of color information and the image becomes desaturated.
but at least it could be a way to solve some specific shots.

just discovered this and didn´t really test it.

so....the latest version of resolve works. but theres still an issue with dabayering i think. or some superblack issues?? lots of red pixels in the blacks. and acr seems to have an automatic hot pixel remover.

i made some testhots using an old esser gray scale test chart. resolves bmd preset + the auto correction of resolve gives pretty similar results than acr+after effects.

when i generate a lut using the grade settings everything explodes (pixel mismatch, overexposure...)

is anybody working on that pink frame issue? i don´t trust there any "fix it in post" approaches.

Tragic Lantern / Re: Raw video on 50d and 40d
« on: June 23, 2013, 07:07:24 PM »
No NR but everything else is there including the Tracker. BMD Film settings just seem to work for me (and quite a few others it seems) and I'm using Arri LUTs for a base to grade from. The BM Film LUT is nice too but saturation needs toning down a touch.

yeah, two arguments for me for ACR.

NR is a must for raw files. and ACR has the correct canon image settings.

everything´s of course in a very early stage of development and for now it´s okay to drop just any lut on the footage just to get things working. but a lut is a very powerful component. and you can be assured that a arri alexa lut also corrects some flaws of the alexa sensor. what´s good for the alexa or bmd cams can for example emphasize noise with the canon dngs or it provokes false colors. and a grade based on false colors can get pretty uncontrollable.

resolve will be the future first choice. no doubt.
just can´t wait to see resolve 10!
could be the perfect way of avoiding any intermediate format.

cool rommex. will give it a try.
but there´s no noise reduction in the free version, no tracker.....or did they change that?

i made three short test videos (with the 550D, see in my posts) and all happened in after effects through acr. and i never had flickering issues.

yes, i used all the bmd settings (is it somehow confirmed, that bmd settings are correct. or does it just "fit" somehow?)
maybe i´ll get some stable shots today. have some charts and gray boards here and try to get some comparable images and maybe generate a LUT for the 50D. time to take that book of the shelf.....  color correction handbook ......good extra reference for resolve!

just need to finally read it  :P

Tragic Lantern / Re: Raw video on 50d and 40d
« on: June 23, 2013, 06:03:50 PM »

but do you also have the problem of flickering images in resolve? every now and then theres a heavily darker image.
and there´s some blue and red noise at the image borders.

sorry for my questions but visually ACR gives me from the start  less noise and since ACR is optimized for photo camera raw and the different raw interpretation methods of ACR changed during the last years noticeable. i think there´s a lot of optimization going on in the background. also not to forget the easy possibility to remove CA.

but i´ll continue experimenting with resolve.

edit: just compared one shot in ACR to resolve. somehow pink (maybe) dead pixels visible in resolve are gone via ACR.

thank you andy!

pretty frustrating since i use resolve for a while, but somehow the images come pretty dirty and noisy in resolve.
i still prefer ACR, it is much slower but the images are a lot cleaner.
or is this all just a preview/real time issue of resolve?

using 1%s side effects build the pink images are gone for some image size settings. will keep testing on this.

what´s the reason for the pink? is it a recording or a decoding/debayering issue?

Tragic Lantern / Re: Raw video on 50d and 40d

with 1%s latest build 80point1 i get nearly 80 MB/s writing speed in 1920x1072 @ 24 fps on a 64 GB Komputerbay x1000 card.

the first frame is in 80% of the files okay. all other frames are completely pink. in every .raw file.
tried different drawing modes in 1:1 crop mode but has no effects for me. uncropped mode is flawless.

in other posts i read this is a issue for a lot of people, but there are reports only a few files are corrupted.
what raw unpacker do you guys use?
i´m using raw2cdng  1.1.6 (lowering white levels has no effect since the whole image is affected)

tried to swap rgb channels. no correct solution.
