I added tutorial for Davinci Resolve.

magdesign · 2020-06-19T07:59:22Z

On line: 116 - 125, its the same process as in adobe premiere, so maybe move premiere up and take all NLE together.

I viewed it with https://remarkableapp.github.io/ or with http://rst.ninjs.org/ and I think there are some formatting issues. Would you add me to your fork so I could fix them....

Yes, but please take in account that Davinci Resolve also has Media Management which allow us to transcode the video without adding it to a timeline. It's the same as Adobe Prelude.

magdesign · 2020-06-19T09:39:42Z

Just learned something from you:

In DaVinciResolve

Select your videoclip
Go to File => Media Management
Select Clips
Select Media Destination
Select Video format => TIFF or EXR
Click Start

magdesign · 2020-06-19T09:53:17Z

Just played thru the Blender way:
- In Color management change view transform standard <= this is on by default, so we could remove this step?

magdesign · 2020-06-19T10:02:59Z

WinFF as mentioned under ffmpeg is not able to export image sequences as a simple gui selection operation...
I recommend to remove this

magdesign · 2020-06-19T10:24:37Z

FF Multi Converter
official link: https://sites.google.com/site/ffmulticonverter/download

Maybe someone can help here, tried to extract image sequences, but it did not work at all.....openend an issue: ilstam/FF-Multi-Converter#64

so I will not write a "how to" for this...

@hellocatfood: if it does not work on your side, lets remove this as well since other people might have the same problem....

devernay

I will fix:

proper link to the tutorial in getstarted-troubleshooting
link from the main TOC

@lehuan5062 @hellocatfood @magdesign do you want your name to appear in the list of Natron doc contibutors? If yes, tell me how you want it to appear.

devernay · 2020-06-19T22:20:26Z

Merges, should be available soon in https://natron.readthedocs.io/en/rb-2.3/guide/tutorials.html

Feel free to propose further modifications.

I think @cgvirus had answers for the 10/12 bits question (using TIFF rather than PNG), can you incorporate these?

devernay · 2020-06-19T22:23:11Z

I think it would be great to also add a section on how to remux audio in the second part

cgvirus · 2020-06-19T23:18:57Z

Oh no! I have made a serious boo-boo.
@devernay please can you update this?

This commands should be here instead those.
https://natron.readthedocs.io/en/rb-2.3/guide/tutorials-imagesequence.html#ffmpeg

Usually we use no alpha for video as they don't contain any. Talked with ffmpeg folks and these are now the correct arguments.

PNG (with Alpha)
for 8 bit
ffmpeg -i input.mp4 -pix_fmt rgba output_%04d.png
for 16 bit
ffmpeg -i input.mp4 -pix_fmt rgba64be output_%04d.png

PNG (without Alpha)
for 8 bit
ffmpeg -i input.mp4 -pix_fmt rgb24 output_%04d.png
for 16 bit
ffmpeg -i input.mp4 -pix_fmt rgb48be output_%04d.png


TIFF (with Alpha)
for 8 bit
ffmpeg -i input.mp4 -compression_algo lzw -pix_fmt rgba output_%04d.tiff
for 16 bit
ffmpeg -i input.mp4 -compression_algo lzw -pix_fmt rgba64le output_%04d.tiff

TIFF (without Alpha)
for 8 bit
ffmpeg -i input.mp4 -compression_algo lzw -pix_fmt rgb24 output_%04d.tiff
for 16 bit
ffmpeg -i input.mp4 -compression_algo lzw -pix_fmt rgb48le output_%04d.tiff

Only DPX supports 10/12 bit in ffmpeg image formats. There are hacks with YUV in TIFF but that is not supported perfectly in many software like Nuke and Premiere itself.
Instead going for 16 bit directly is safe.

cgvirus · 2020-06-19T23:28:04Z

%04d specifies the position of the characters representing a sequential number in each filename matched by the pattern. Using the above example the output files will be called output_0001.png, output_0002.png, output_0002.png and so on. For longer videos one will need to use a higher number (%08d.png). start----->

Here are some more options:

PNG (with Alpha)
for 8 bit
ffmpeg -i input.mp4 -pix_fmt rgba output_%04d.png
for 16 bit
ffmpeg -i input.mp4 -pix_fmt rgba64be output_%04d.png

PNG (without Alpha)
for 8 bit
ffmpeg -i input.mp4 -pix_fmt rgb24 output_%04d.png
for 16 bit
ffmpeg -i input.mp4 -pix_fmt rgb48be output_%04d.png

To extract TIFF 16 bit image sequence:

TIFF (with Alpha)
for 8 bit
ffmpeg -i input.mp4 -compression_algo lzw -pix_fmt rgba output_%04d.tiff
for 16 bit
ffmpeg -i input.mp4 -compression_algo lzw -pix_fmt rgba64le output_%04d.tiff

TIFF (without Alpha)
for 8 bit
ffmpeg -i input.mp4 -compression_algo lzw -pix_fmt rgb24 output_%04d.tiff
for 16 bit
ffmpeg -i input.mp4 -compression_algo lzw -pix_fmt rgb48le output_%04d.tiff

<-----end Notes For TIFF

There is a step need to be added to Davinci Resolve

lehuan5062 · 2020-06-20T06:12:14Z

Documentation/source/guide/tutorials-imagesequence.rst

+- Select Media Destination.
+- Select Video format => TIFF or EXR.


There must be one step before this so the Video format setting can be available:

Select "Transcode" mode.
And that step should be placed before "Select Media Destination" in order of the interface.

The next step should be:

In case they may have used any media.

Should we include codec suggestion in our document?

-Da Vinci Resolve
-~~~~~~~~~~~~~~~~

(Ignore this suggestion if you prefer the general method for NLE).

When importing, select all the images to import it as a sequence.

In Resolve, select the image sequence(s).

Go to File => Media Management.

Select Clips.

Select "Transcode" mode.

Select Media Destination.

Select the desired Video Format.

I think we would want to replace the "your".

magdesign · 2020-06-20T12:01:22Z

I think it would be great to also add a section on how to remux audio in the second part

Remux audio means adding audio to the outputed video?
So we would make an example for adding stereo and 5.1 with ffmpeg?
Does this really comes into the Natron doc, isn't this just a regular thing most users do in a NLE?

magdesign · 2020-06-20T12:05:55Z

@lehuan5062 @hellocatfood @magdesign do you want your name to appear in the list of Natron doc contibutors? If yes, tell me how you want it to appear.

Thanks for accepting our work, I think we will keep on writing on the docs and therefore we could also add our names in the next pull request directly to the https://natron.readthedocs.io/en/rb-2.3/index.html section ...

Hey I had some experience with broadcasting and remux is slightly different than "adding audio to video". Normally, when we add it in a NLE, we render the final out. And that is "render" or "transcode", not "remux".

Remux is we add audio to the packaged/compressed/rendered video without them being rendered again. It's usually happen when you stream/record multiple audio sources when/after broadcasting. I'm not an expert and this is just my little knowledge.

cgvirus · 2020-06-20T15:27:18Z

Remuxing with audio re-encoding

ffmpeg -i video.mp4 -i audio.wav -c:v copy -c:a aac output.mp4

Remuxing without audio re-encoding. Make sure your movie container can accept the audio file format. MKV can take almost all audio format (ogg,flac,opus,wav,mp3)

ffmpeg -i video.mp4 -i audio.wav -c copy output.mkv

Yes, this involves an external tool, and I meant the ffmpeg commands @cgvirus mentionned above, but one could use a NLE such as Shotcut to do this as well. The doc should mention it

cgvirus · 2020-06-20T19:39:39Z
