Which lens do you use? And do you use Polarizer? (probably yes)

I've used only a Sigma 18-200mm DC OS II lens.
Not the best lens but it's all I have for now.
I haven't used any Polarizer filter (in fact it doesn't came to my mind to use one, I'll try to use one in my next shoots, thanks for reminding me this filter can be useful !)

Is this in slow motion or time lapse? Thee clouds are so beautiful very nice shot choices

Thanks you !

The videos have been shot in RAW 1536*654 @24fps, which let me about 16 sec max per clips with my SanDisk Extreme 45MB/s.
I haven't changed the frame-rate at editing, so the motion speed is the real one.

Hi guys,

Here is a new RAW Video I've made using .MLV Format on my 650d, using the April 22 Alpha built.

Here is the video I've made using .MLV RAW Format with my 650d :

Right, just upload a sample DNG without any processing (without chroma smoothing).

Here it is :

(you have to click on "yellow dots on sun with cs.dng" on the top of the page to start the download)

With chroma smoothing (2x2, 3x3 and 5x5), a lot of yellow dots appears on the sun.

Hi,

First thank you for your contribution tonybeccar, your program is very usefull !

I gave it a try this afternoon with some RAW .MLV videos, and I found out a problem with the 2x2 chroma smooting : yellow point appears on the very bright areas :

DNG From MLV file without chroma smooting (converted with Adobe Camera Raw)

DNG From MLV file with 2x2 chroma smooting

As I'm a 650d user, I need chroma smoothing to get rids of the pink dots.
I remember a "raw2dng_cs2x2_white_fix.exe" was released for .RAW processing, I guess the same fix need to be done with .MLV files

Also, I've installed IrfanView v4.37 with all its plugins, but no video preview are displayed (I linked "i_view32.exe").
I don't really care about the preview, it's just to inform you in my case it doesn't work.

Again, thank for the time you spent on this software, keep going !

I will post my test video soon.

Thanks for posting your video test dsagilles. Do you see these artifacts on the raw video? Or on the video that you upload to Youtube? They look like compression problems to me, so I'd be very surprised if changing the lens helps much. If the raw video is clean, it would be worthwhile to try and identify at what stage these artifacts are being introduced. But if the raw video already looks like that, what is the point of shooting raw? So far I've never seen such results on any of my footage recorded as bog standard Canon mov.

The green/yellow artifacts are in the original RAW footage.
Yeah it's looks like a compression problem, but it's not the case because I have the same result on the uncompressed AVI out of After Effects.
The aliasing, the chroma smoothing and maybe a too strength color-grading aren't helping.

I think we can't see all theses artifacts on Canon MOV because of the compression, adding a global blur and maybe a kind of anti-alias is applied on the compression stage.

Is this RAW or H.265?

This is RAW. I was very surprise of the result quality too. On my previous videos I haven't shot wide scenes, so I wasn't able to see all theses problems.

It would be cool if someone could try out a RAW shot on a similar scene.
Trees seems to be the worst thing for our 650d RAW.

I just uploaded a new RAW Video test I made, where - unfortunately - we can see a lot of aliasing & artifacts.
I'll try to get a L-Lens to compare the quality with my Sigma 18-200 in RAW/h264.

I just uploaded a new RAW Video test I made, where - unfortunately - we can see a lot of aliasing & artifacts.
I used the raw2dng_cs2x2_ahdlike_noise to extract the frames (and tried the original raw2dng to compare but the quality was quite the same - except there was the focus pink dot pattern of course).

If you have some shots with aliasing (caused by line skipping), can you check whether chroma smoothing has any effect on them? (be it good or bad)

The problem is I directly extract frames with a chroma smoothing, so I can't really see the difference.
But if I see any issue, I will report them here, no problem !

Here's another raw2dng that does a little less chroma smoothing (it only considers top, bottom, left and right neighbours). It still removes all the pink dots.

raw2dng_cs2x2_ahdlike_noise.exe (fewer artifacts)

(actually this kernel is more like 2x2+1)

I've just tested it and it seems to work pretty well, remove a lot of dots/artifacts where PDR doesn't !
I've updated my RAW post processing tutorial and allowed myself to link your raw2dng version, I quoted you of course (http://www.gna-productions.com/tutos/how-to-process-magic-lantern-raw-videos , part 3), I hope you don't see problems.

Thanks, and again (not again but it was in my mind since the beginning) : good job !

Are you saying that GNA is running an older version of Magic Lantern (...)

That's right, I'm using an old version of Magic Lantern (v 08.08.2013) because I experience problem removing pink dots with the recent ML builds at 1476x626 (PDR seems to have no effect at all).

Be sure you're using PDR v0.8 to process directly .RAW files. If it's the case, you still can extract all frames with RAW Magic and process frames with PDR, but you'll need the double of disk space to process all your videos. I've a mac too but I haven't tried processing RAW since the last version of PDR on OSX.

PDR works fine with any resolution and aspect ratio with one limitation:
The height and the width must be a multiples of x16.

So i'm using 1600x672 (2,38:1), 1584x688 (2,3:1), 1568x656 (2.39:1) and others.

Thanks for the information, I'll give a try with one of those aspect ratio.

I'll do more RAW test with the latest ML version and try to find a quicker workflow using Davinci Resolve (OSx).
Maybe I'll do a complete video tutorial for RAW processing on Windows and OSX. (in French with English subtitles).

I'll keep you posted !

Hi! Can you provide us your workflow/camera settings you used for those timelapses? That would be great! Thanks

I shot mainly in RAW or RAW HDR with my 32GIG memory card.
For night I've used 10sec exposure ISO 100 and my 50mm prime lens at f/1.9 for the shot with the city, and same parameters but with ISO 400 for the one with the tree and stars. 10sec exposure is the limit, after that the star's motion is too much visible. I set something like 12sec of intervals between pictures.
The day time-lapses was shot between 1 and 5sec intervals. For HDR, when the dynamic is high I used the Magic Lantern bracketing, which can be much higher (+5 - 5eV) than the Canon one (-2 +2eV), but ML Bracketing speed is also slower than the Canon one, which might be a problem with "fast" motions.

I used After Effect to output 1080p 8bit lossless video of each time-lapses, color-graded direct at import with Adobe Camera Raw for most of them.
For HDR, sometimes I used 3 AFx layers with each of the bracketing I compose by using a luma-key, sometimes I used ginger HDR merger to create a full range exr file. But i'm not good at HDR compositing for the moment.

After that, I just have to edit the final video using Premiere !

Another excellent video dsagilles!

Thanks !

I'll do some dual ISO test soon.

I've also upload a timelapses compilation I've shot this summer :

Here is some of my videos, shot with my 650d and Magic Lantern.

Thanks for watching !

I've shot a new RAW video, this time in MACRO style using a vintage Minolta 35-70mm lens.
I hope you'll enjoy it :

I've wrote a tutorial about processing RAW files with After Effects and Camera RAW, you can find it here :
http://www.gna-productions.com/tutos/how-to-process-magic-lantern-raw-videos

I've also done some comparisons between RAW and H264 with different picture styles this week, if you're interested here is the video :

I can confirm a SanDisk extreme 45MB/s (at least the 32GB version) is fast enough for 650d RAW.

A ML Benchmark gives performance around 40MB/s both in read/write (Max write : 41.3 MB/s, Max read  : 42.6 MB/s).

Yes, something wrong for sure. Have you tried another aspect ratio and/or resolution?

Nope but I always use this resolution, and PDR 0.8 works great with same resolution files from an older ML version.

Don't know what are you talking about. Just tried latest PDR on 31.08 ML build and everything is just fine.

By the way, check out my fork of PDR, it has much less artifacts for now.

PDR rewind 2

Weird.
Here is a frame example which I can remove pink dots : https://copy.com/ULWAYsZ2Zb43
If you could try to remove them it would be nice.

(Extracted using RAW2DNG on the original RAW file. I also tried processing directly the RAW file in PinkDotRemover without success).

Pink dot remover (v0.8 and v0.7 ) seems doesn't work on the RAW from the latest ML version (31.08.2013).

See my post in the PDR topic here : http://www.magiclantern.fm/forum/index.php?topic=6658.msg72551#msg72551

The pinkDotRemover (v 0.8 and 0.7) doesn't remove pink dots on RAW/DNG files shot with the latest ML for 650d (31.08.2013).

I've try 2 RAW videos in the same condition except ML version :
- Nothing is removed with PDR on the latest version (31.08.2013).
- Pink Dots are removed fine with an older build (08.08.2013).

The pink dots pattern seems to be the same with the 2 versions.

I guess something had been changed recently concerning the RAW module (plus I can't install the old raw module on the latest build : it says it's in "V2" and a "V3" is expected).

Use the debug release. It can process raw files directly:
http://www.magiclantern.fm/forum/index.php?topic=6658.msg62437#msg62437

Oh sweet ! Thanks !

I would first use the PinkDotRemover because there are not so many file operations which makes it faster.

PinkDotRemover (v0.7) only convert .DNG files, not directly .RAW .

The 14xx resolution was 1:2.35 not 16:9. 1472x838 is likely too high for continuous recording

Exactly !

Even if ML doesn't always say "Continuous OK", it looks like it is.

Also it's possible to shoot something like less than 10sec at 16xx 2.35, which might be handy for some very short shots.

Very nice,

Can I ask how long it took you to work through the process from extracting to remove dots etc, to final film?

Thanks

dave

Sure, and you're lucky : I've timed most of the process !

Precisely, I've shot 11min12sec of RAW at 1476x626 (16 251 frames@24fps), for about 25GB on the memory card.

- The raw2cinema DNG (using RAW Magic on osx) took me 12min21sec (I ran the process directly from the rushes on the memory card and sets the output on the hardrive). Output 28GB of DNG (not 25 due to the 14bits > 16bits conforming I guess).
- PinkDotRemover tooks 34min44 (And gives me another 28GB of dots-free DNG). I used search expression (which I don't remember sorry) to selects all DNG without initial underscore (_) and delete them in order to keep only the dots free DNG.
- Finally, After Effects exports all rushes in uncompressed 8bit color-graded videos within 2h10 (Output : 39.7GB, always in 1476x626).

So globally, processing a RAW file from .RAW to 8bit video takes 15min for 1 minutes of shooting.

I haven't timed the final editing process (done with Premiere pro), but it was fast as all rushes were already processed in uncompressed 8 bits videos.
