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.

Here's my first attempt at shooting RAW. The workflow is a lot bigger, but worth every second I think!

Shot in 1088x480 @ 24 frames per second with a 16GB Sandisk Extreme 45mb/s.

RAW > RAW2DNG > 14-bit DNG's > Adobe Camera Raw > .tif image sequence > Adobe Premiere CS6 > upscaled to 1080p > rendered out to .H264

How did you upscaled it ? What you used ?

I put the 1088x480 footage into a 720p sequence in Premiere and simply 'scaled to comp' and then my entire edited sequence into a 1080p sequence and used Instant HD and upscaled it to 1080p. Looks alright I think, though I'd probably just stick to 720p next time.

You did a great job: things that appear blurred are blurred by lens and wanted as is, because the sand touched by waves and waves on the horizon are very crisp and detailed, so upscaling is very good indeed ! Very good, compliments !

Thanks, man. Appreciate the kind words!

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:

Code: [Select]

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 :

Code: [Select]

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:

been playing with raw for weeks,
i got some black frame sometimes. (not sure when it will occurs)

all frames on that raw after converted to dng is all black, in camera preview is black too.
im sure the i have LV showing when i do the recording.

this is a known issues?
(ive read ppl getting some bad frames, but not whole clip is black)

You can write down as much details as possible (Canon mode, ML mode, fps override, resolution, at what frame numbers appears the black frame... and so on), so we can build a case-history to track down the problems about bad-pink-black-screwed-up frames that appears from time to time, many thanks !

In this mode 1280x426 (3:1)
With this build i can get 1100-1200 frames with sandisk 45, and 1640-1650 with sandisk 95, so there is again difference in about 50%.
I think there are more things going on besides just writing speeds here.

Excellent work dude, amazing!

Is there any plans to add 1088 as a resolution to future builds?

That's not my work, dude. Thanks to devs, A1ex & co. )
Also thanks to mk11174, who made this great tutorial for code-starters )

Watch it, and then you'll can easily add whatever resolutions you want, and much more (that's exactly what i've done: just added a couple of numbers to raw_rec.c file).
At it best, you will want to dig in, and hopefully find some interesting ideas about memory allocation, buffering and other delicious stuff... So welcome aboard )

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?

That build compiled with just raw_rec module. You have to disable or delete other modules in order to use it.

Ah, didn't realise, sorry! I'll certainly give that a watch, thanks man!

canon mode im using is 1080p 30fps
ML mode not 100% sure,
-did use fps overrite (23.967 and lower as well)
-no memory hack
-resulotion i did use alot of combinations ( hard to tell w/o the clips now )
-its not numbers of black framesm its the whole clips was black frames
-seems only occur the first few recordings after turn on the camera ( might be the 1st second or 3rd), all my others clip that record behind seems to be fine.

i will try to playing it more, to get more infos (i didnt keep the black clips

)
