wow, looks really nice!
#27
People using twixtor - is interpolating 18fps to 24 a big deal? Will the result look acceptable?
#28
I'd like to avoid buying more programs than I already have.
#29
I tried ProRes and x264 via ffmpeg, but still can't get the same colors I see on tif files I processed with Lightroom. Any ideas, why? It's as if resulting video lacks saturation or warmth.

#30
I actually can't install Rewind's build. It keeps giving me error when I load modules. How do I update from mk11174's build? Just copy>replace files, right?
#31
However is it -pix_fmt  yuv444p10be or -pix_fmt  yuv444p14be ?

ffmpeg -vcodec tiff -i &6d.tiff -r FPS -vcodec prores_kostya -profile:v 3 -vendor ap10 -pix_fmt  yuv444p10be -y -r FPS OUTPUT.mov

cd to your folder containing tiff.
replace both FPS with your actual fps!

Thanks, exactly what I needed!
#33
What's the command line to convert to ProRes? I'd like first to work on dng's in Lightroom then export tif's to ProRes
#34
Raw Video / Re: 5D3 Raw 4:2:2 or 4:4:4?

When I look at ffmpeg documentation for -pix_fmts it lists yuv444p14be and yuv444p14le formats, which should be good enough, no? Why is ProRes better?
#35
Am I stupid or OSX version just does not work? I run in terminal and get -bash: raw2dng: command not found

I did chmod a+x for the executable, does not seem to help...
#36
For those of you who want a quick command line solution without any processing (and free!). Install ffmpeg. From command line switch to a directory with exported tif files, then run:

ffmpeg -f image2 -r [your frame rate] -pattern_type glob -i '*.tif' -vcodec libx264 -preset ultrafast -qp 0 -pix_fmt yuv422p movie.mkv

-r sets frame rate value
-pattern_type glob -i '*.tif' scans all tif files from the current directory
-vcodec libx264 -preset ultrafast -qp 0 -pix_fmt yuv422p means fast x264 compression with highest quality setting and YUV 422 chroma subsampling

If you need to upscale, then add [-sws_flags lanczos -s WxH] . For example to upscale 1344x488@20fps to 1920x640 :

ffmpeg -f image2 -r 20 -pattern_type glob -i '*.tif' -vcodec libx264 -preset ultrafast -qp 0 -pix_fmt yuv422p -sws_flags lanczos -s 1920x640 movie.mkv

This is a very fast way to export. You can use -preset veryslow, then files will become less in size, but it's time consuming.

And here's another test:

Here's another test with mk11174's build



Settings:
Canon's 1080p@24fps mode
ISO 100
1344x448 @ 20fps (Hi Jello)
5x mode
Toshiba Exceria Type 2 16GB card

Settings in Lightroom:

Luminance = 0
Color = 45
Detail = 100

Sharpening = 10

WB

Temp = 5050
Tint = 0

Everything else as is. Noise reduction blurs details significantly, regardless of how I tweak different settings, so I 've set it to 0.
#38
Guys, is there a guide for noise reduction? I am getting a lot of noise by default, even at ISO100 :(
#39
I formatted the card on a computer, then did low level formatting in camera. Copied all files from the ML_550D_June_20_2013_Update01 folder and prepared a card. Still the same error when loading modules. This can not be a coincidence. I even re-downloaded the archive

UPDATE: Got it working. Not sure what happened.

I noticed that I am getting slightly more frames in 1:1 mode than without it.
#40
Guys, I don't know what you did, but with "ML_550D_June_20_2013_Update" I am getting continuous recording in 5x mode at 1344x448 (3:1) and 20fps (Hi Jello setting).

At 21fps >788 frames!

AMAZING!

Some more tests:

1472x490 @18fps = 478 frames
1472x552 @18fps = 178 frames

I am using Toshiba Exceria Type 2 60MB/s card

ML_550D_June_20_2013_Update01 still does not work. Anyone else having this issue?
#41
ML_550D_June_20_2013_Update01

Getting linking error when loading modules.

undefined symbol 'raw_lv_shave_right'
[E] failed to link modules
#42
Wow, great progress, guys. Going to try this tonight, when I'm back from work!
#43
I guess anamorphic lens is the only way we could get more resolution with 550d?
#44
even if it was possible, the workflow would get even more complicated...
#45
@mk11174, Thanks for the guide! Going to try it soon
#46
Also interested!
#47
5x is the 1:1 crop mode. Disabling 10x is under LiveView Zoom Tweaks menu
#48
Guys, just wanted to share my workflow on Mac here, if anyone is interested:

1) use raw2dng.app to export frames
2) import dng's to Adobe Lightroom
3) white balance / tint correction, if needed
4) export to tif (frames become 4 times the size of dng!)
5) Next you need to make sure you have ffmpeg installed. In Terminal cd to the tiff directory and run command:

ffmpeg -f image2 -r 24 -i %6d.tif -vcodec libx264 -preset veryslow -qp 0 -pix_fmt yuv420p -vf unsharp=5:5:0.5 movie.mkv

This is supposed to produce almost lossless output, however I am not sure about that. Maybe it's better to use yuv422p or yuv444p ? Unsharp filter is used here, because by default the output is quite blurry.
#49
Got a crash after first time launch with this build. No issues afterwards, but my fav resolution width 1408 is gone.. Will have to downgrade
#50
guys, how do you embed videos in posts?
