"Apple ProRes 4444 XQ and Apple ProRes 4444 support image sources up to 12 bits"
https://images.apple.com/final-cut-pro/docs/Apple_ProRes_White_Paper.pdf
the ffmpeg encoder for example only supports ProRes444 with 10-bits

Raw Video / Re: pink sun?

Is there any way to avoid this with a camera setting?
This is the only issue I have with ML RAW from time to time.

It would be great to have TC in your converted Files. It already works with raw2cndg and resolve.
But i would like to get it to work with mlrawviewer. It uses ffmpeg which has a command to set timecode, but i haven't figured out how to pass the tc info of the mlv into the hh:mm:ss:ff format that ffmpeg's -timecode command needs.
Another great thing would be to pass all the metadata to the converted files ( iso, shutter speed, lens etc.) even if it's just a burn in text, like in the image from the first post of this thread.

I wouldn't say it's the 'only' reason for me to shoot raw, but for me it was as well one of the main reasons to get further into ML-Raw. When all your MLVs are indexed it is even faster to look through your raw files, then through your canon h264 movs with the quicktime player, and with all metadata + histogram.

Modules Development / Re: Magic Lantern (RAW) Video format v2.0 (mlv_rec.mo)
« on: January 11, 2016, 10:06:53 PM »The dream is already true see the OP:
LZMA is kinda slow and doesn't compress as well, but LJ92 is superfast
Does this mean it is possible to use the LJ92 compression for mlv files? With mlv dump?

Andrew Baldwin wrote something about the compression method he used for MLRawviewer here:

MLVProducer looks promising but right now it doesn't give me real time playback and i have to adjust a lot to make it look good, thats a lot slower than to just batch convert everything in one go.
With Mlvfs you also have to adjust your files. The key for me with mlrawviewer is that i can select a colorspace and just export all files without touching the settings (except white balance) and get decent results.

Does anybody know how to create movs with mlrawviewer that have the creation time as timecode?
Mlrawviewer shows the creation time (and other usefull metadata) when you open a file.
There is a command for ffmpeg to set a timecode ( -timecode hh:mm:ss:ff) but i don't know how to pass the data from the mlv to the mov. I found a few things like burning in tc with the -drawtext command but I never got it working.
It won't be frame accurate like proper timecode, but it would help to sync multiple cameras or external audio with timecode. And its a pity you lose all the metadata once you convert to mov (iso,lens,fstop,aperture,shutter speed)
P.S.
So it really seems there won't be another version of MlRawViewer, that's a pity because it's such a great App. It was the reason that I started to really use the raw feature of magic lantern because it made the raw workflow really fast to use.
But there are a few things that aren't completly work right now.
With the latest build i can't use the C Key (batch export all files in folder) so I'm still using version 1.3.4 (and it's easier to select a target folder in the old version).
There are a few other things but I don't know anything about python or coding in general.
Just wanted to thank Andrew for his effort, it's still the best app for mlv imho.

Camera-specific Development / Re: Canon 5D Mark III / 5D3 / Firmware 1.2.3
« on: March 26, 2015, 07:15:20 PM »
Do you have "DSLR Scale" activated on the AC7? It crops the incoming signal because Canon DSLRs used to output the image with a black frame around the image. FW 1.2.3 changed the output to Fullscreen so You don't need the feature on a 5DIII.

Thank you Baldand for the latest release and all your work!
I also seem to have trouble with the sound in 1.2.0/1.2.1 when converting to ProRes.
.raw conversion works as expected as well as the new fps override.
When I try to convert a mlv with sound the files stays at 0% in export queue and then just finishes without a error message.
The log file said something about "stdoutWriter"
I looked at the wav file that is created in the source folder and it is fine when i just play the mlv, but after the failed conversion it overrides the wav and it becomes unplayable with a filesize of 1KB.
I used 5D III footage on Win7

« on: August 07, 2014, 05:34:47 PM »I saw in the code that FFMPEG is executed with "-profile:4". No need for another symbol in the UI, but it would be really cool to switch between profiles or even the constant quantizer mode (maybe a config file?). I think ProRes 422 would sufficient for most cases...
http://transcoding.wordpress.com/2012/01/29/prores-ffmpeg/
That would be great! Rawanizer had the option to write the ffmpeg code in a textbox or use presets, but config file would be good for mlraviewer.
I tried to modify the prores profile in the python source, but i don't know anything about compiling it to an executeble.

Raw Video Postprocessing / Re: DNxHD presets, how to output 1920 anamorphic?
« on: July 28, 2014, 12:45:54 PM »
DNxHD only supports standard resolutions: 1920x1080, 1280x720.
ProRes is resolution independent.
