Nice to see someone picked up the efforts to bring holygrail-timelapse to "Free-+Software"!

My last trials are from 2013, and for the sake of convenience i switched to Lightroom/LRTimlapse.  ;D

My conclusion over the years:
Use ML-ETTR to make the best possible picture, Postprocessing (deflicker, ramping, adjusting exposure to taste) is done easiest and best with dedicated software.
Trying to adjust the exposure with scripting is very cumbersome.


Questions 1:
---------------
I see that in the sidecars produce by post deflicker, there is two parameters that I'm not using
<ExposureNorm>1</ExposureNorm>
<ClipHighlights>film</ClipHighlights>

Do any of you know what are their purpose and what they actually do ?


The parameters are for developing the raw-files in ufraw. So no use in Rawtherapee.

Happy timelapseing!

I would guess, the displacement is due to the lens stabilizer being on and reacting to vibrations on tripoid. Or the stabilizer is out of order, but the fault is only visible on tripoid. Your problem is only visible during timelapses (typically done on tripod), because handheld it would be impossible to notice.

Hello,

as a fellow 550D-Owner i try to answer, but not in depth, coz that is outta my knowledge.

- RAW and MLV are 14bit, other bit-sizes are only aviable to some cameras i.e. 5D MarkIII.
- Different Iso should change exposure, thus changing from ISO100 to 320 should blow some highlights.
- A DNG from RAW-Video is different from CR2, but both are Digital negativs.
- Regarding bitrate for H.264: IMHO increasing CBR doesn't improve quality in a visible way. For that reason developement is abandoned.

I hope my answers in a nutshell, shed some light on your questions.

Hi, the AGC is turned off inside the DIGITAL GAIN Submenu (2nd row).

General Help Q&A / Re: FRSP
« on: January 19, 2017, 08:25:52 PM »
Hey garry,

I've done FRSP-Timelapses processed with LRTimelapse some months ago. Iirc It works by using the Visual workflow and changing some advanced settings. There is a option to do visual ramping instead of using Exif-data. Of course it takes longer than the basic workflow.
But as stated above the gradient of the FRSP is sometimes clearly visible, so i would recommend using Cr2 and autoettr for getting best results.
With exposure time limited to 1/10 it's hard to avoid blown highlights with sunny weather, even with ND-Filter.

Did some tests on the 550D with latest build from dfort:

12bit is now stable in 1080p25 and 720p50 (fps override to 24 of course)!


12bit-1080p25

12bit-720p50


10bit still results in every second frame corrupted

10bit-720p50


5x zoom creates a camera crash (Err70)

Code: [Select]
ASSERT: dwDeadLine != 0xFFFFFFFF

What a simple solution! I've missed the "unread posts" link for about a year now, but never dared to ask. ;D

I guess you're talking about the HDR-workflow-051.zip?

It's been a very long time since i last used it, so here is my guessing:
Did you choose the wrong frame rate in virtualdub (video/ frame rate)?
The script assumes the frame rate to 25 fps.

Normally the resulting frame number is reduced to half, i.e 480 frames result in 240 A and B frames, getting merged to 240 C frames.

When using LRTimelapse for timelapses use the "Visual Workflow" with silentpics. Under Expert settings check "Use optical Keyframe...".
I have done this now severel times and works fine.

@jankrueck:
In the end everything you see on your monitor is an interpretation of the sensor-data depending on your software (debayering).

I recommend reading the cinelog thread of Andy600. He gives a good insight of colorspace and the whole sience behind it.

Left column (Presets) in export dialog: No Magic Lantern, no Dual ISO Converter entry.

Can provide english menu, too.



The same happened to me too (LR 5.6 german, Win7) after installing V3.Beta3.
BUT after hitting "Export" in Export-dialog (window above) a preset for DualIso-Export was created, including an entry in context menu.
So all works fine now. But i guess there shouls be a preset right after installing a plugin in LR.
I have no LR at hands right now, so i can't show a screenshot.

Very impressive, especially the beginning inside the church!
No blown highlights, no noise in the shadows.
Getting the right moments with only one chance.
Excellent work.
Did you shoot that with a single cam?

Looks like you linked to the wrong File?!



I'n not having any troubles developing this one.

Edit2: Ufraw-batch is now looking for a CR2 - when obviously I have used CR2HRD to create a DNG. Obviously there isn't a converter to go back again - what's best here?

I got no original .ufr-file by hand, but my guess is that you would have to rename "CR2" to "DNG" inside the ufraw-sidecar.

For example:
<?xml version="1.0" encoding="utf-8"?>
<UFRaw Version='7'>
<InputFilename>E:\ufrawconvert\raw\IMG_2918.CR2</InputFilename>

to

<InputFilename>E:\ufrawconvert\raw\IMG_2918.DNG</InputFilename>

I never made a timelapse with Dual-ISO but to my knowledge a "flickerfree Dual-ISO Timelapse" can be achieved with the --same-level command.
It's simple deflicker in post-proccessing instead of doing it in Camera via sidecar.

Raw Video Postprocessing / Re: The CinemaDNG Discussion (raw2cdng)
« on: April 06, 2015, 06:19:11 PM »
above the preview-window, on the right side, there is an inputfield (filled with 12345?!). write the frames around the "glitches" into this field. test some frames, that seems not to exist.(129-133 or 150-248). but there will be another patch for longer strips until m99, by now i assume, some of these pictures are inside the splitfiles beyond m20.

Aaah now i understand :)

Ok the results are:

nanual frame    file nbr    frame nbr
    128                  0               128
    129                  5               133 
    130                  6               134

    133                  9               137
    130                 10              138

    147                  2               250
    148                  3               251
    149                  4               252

so indeed it's skipping some files.

About the metadata:
You're right, as a filmmaker you're ought to know your FPS  ;)

I'm still a rookie, so i try to analize my f-stop and shutterspeed when i overexposed etc.
In my case its also helpful for timelapses with exposure-jumps.
Dual-ISO raw video would need the base ISO for deinterlacing.

Thank you once again.

Hello chmee,

another issue that's puzzling me is the metadata of mlv-files (regular video, not FRSP):

In the raw2cdng app i see all the metadata like shutterspeed, fps, focal-length, iso etc.
But in both Lightroom and exiftoolgui i see nothing except cameramodel, framesize, colormatrix and white- and blacklevel.

Is there no way to write the first mentioned metadata inside the dng or am i missing something?

Thx again

Thank you for your quick response chmee!

I'm afraid i don't understand " look with 1.7.1 inside the frame-metadata 128, 129, 130."

I just get:
[previewTimer_Tick] show previewframe 130 from 23550017
[showPicture] started


Clicking "show meta blocks" results in the log-file i posted.
When looking at the log-file i see no inconsistend numbering outside 0 to 150.

If i test the big mlv-file alone it shows 129 frames. -> 129*31 mb = 3999  ~ 4GB. So the math seem right.

Again many thanks for your efforts!
i really appreciate it.

Hey chmee,

i'll give you some feedback... err i have some problem:

I made a FRSP-Timelapse with an outdated built which recorded 1 MLV File (4 GB) and 99 single picture files (.M00 to .M99), which was state of the art back then.
When i open the mlv in raw2cdng it sees 150 frames in 22 mlv-files resulting in dng-files counting from 0 - 128, 133 - 149 and 249 - 252. (see pictures below)





debug.log:
https://dl.dropboxusercontent.com/u/90483500/MAGICLANTERN/raw2cdng.2.debug.log

Do you see a chance to get this working?

Thanks in advance for your generous help and keep up the good work. :)

Hi RLaudi,

this sounds very interesting. I will give it a try in the next days!

two things, why is the shutter limited to 0.8'', i was having wet dreams of full res star trails....

You are not the only one....

For some reason the 500,550 and 600 crash at shutterspeeds slower than 0,8"

Limitations:

- 500D, 550D and 600D can't take exposures longer than 0.8 seconds :(

I tried a day/night - timelapse 2 days ago with an old built from mk1174... well it works, but crashed several times before it run successfully.

And another problem i faced with this outdated build was i couldn't extract all frames from the MLV + .M00 to .M99 files.
(Must have been 130 (MLV with 4 GB) +99 frames but i only got 150)

Right now i'm investigating on how to extract all files.
So in the end i spent more time troubleshooting than taking pictures  ;D

For now i guess it's best to accept the limitation.

Wow, really imperessive!

If i hadn't already heared about Aurora Borealis i would say:
"Nice job...can you make a tutorial how to do this effect in Aftereffects?"  :D

Very nice video!
Is that you and your dog?  :D

@budafilm: If i understood your question right, you wan't to know the duration of a single shoot:
At that low framerate (around 6-8 fps and lower) you can shoot continuous at max. resolution

Yes there is:

Movie Restart

While this setting is on, movie recording will restart automatically, unless you stop it. There will be a few seconds skipped during restarting.

Davinci Resolve can't read the development settings you have done in lightroom. This is only possible by Adobe ACR as it can interpret the settings stored inside the CDng. The Cdngs are still untouched raw-files for Resolve.
