How can you make an HDR video using the .exr files? about hdr_toolbox HOT 10 CLOSED

The outputs are in exr format.

What functions are you using?

I want to convert these exr frames to HDR video viewable on an HDR capable TV. How is that possible.
You need to convert data into 10/12 bit per color channel RAW files and encode them using H265.

from hdr_toolbox.

What functions are you using?

hdrimwrite('frame_number.exr');

The method I'm using is described in "Style Aware Tone Expansion For HDR Displays".

from hdr_toolbox.

is this the full list of commands that you use?

from hdr_toolbox.

I use multiple commands but at the end I generate an image which has scene luminance, similar to the demo_expansion_operators.m only instead of AkyuzTMO, MasiaTMO or other TMOs provided in the toolbox, I use another method I implemented based on the paper I mentioned. I save the .exr files. and they look satisfying when tonemapped using a programm called LuminanceHDR. I have tonemapped every frame of a video and saved it as an exr file. I want to turn these frames into a HDR10 video which I can play on an HDR TV.
If there is any other way I can test the results on video I'd be very glad to know.

Thank you.

AkyuzTMO, MasiaTMO or other TMOs

These are NOT TMOs are ITMOs/RTMOs or EOs, and they are used to expand the dynamic range of an image and not to compress it. Actually, their names are AkyuzEO, MasiaEO, etc.

I have tonemapped every frame of a video

I do not understand this bit, you expand the dynamic range of an image with EOs and then you tone map it, right? This step does not make any sense because you expand the dynamic range and then you compress it again. It's like doing 10^(log10 X) the result of these two operations will be X.

Probably, you need to encode these EXR files using some video codec. Such functionalities are not in the toolbox at the moment. Please try what is suggested here:

I use multiple commands

It is very difficult to understand what you are doing without the full list because your description is a bit confusing.

Sorry my bad. I meant iTMO not TMO and by tonemapping I meant expand. I expand the video frames and save them in EXR format.

Yes I need to encode these hdr frames. I thought this capability might be built in the toolbox or there might be some more intuitive software because I don't have any experience encoding videos.

No worries, but everything was very confusing.

It cannot be done using the Toolbox, please check that link. I will close the issue if you have no further questions.

No further questions.

Thanks.

Thanks for useful toolbox.

Hi, I'm also confused about how to covert the .exr hdr files into hdr10 video?

from hdr_toolbox.

There are no functions to convert .exr videos into HDR10 videos. For that task, you need to use FFMPEG or similar software.
