Aquisition metadata on video files from Sony cameras - ISO, aperture, shutter...

[Phil Harvey]

Great, thanks!  I'll add these.  I guess 6 should be "Custom" then (it seems that Shade may be implemented as a Custom setting).

Fantastic!

kamil, im also dumbfounded with the aqcuisition metadata. did you find focal length in there somewhere?

Is there any chance exiftool can "write" Sony Aquisition metadata into existing video files?
This is especially useful for those using adapted manual lenses, thus missing FNumber field in the recorded video files.
Populating FNumber will enable Catalyst to use the gyro data to stabilise video files recorded with a manual lens.

[Phil Harvey]

If the FNumber exists in the file, but is zero, there is a remote possibility that I could eventually add the ability to write this (as long as it isn't in the timed metadata, which I fear it may be because I think that "rtmd" = "Real Time MetaData").  But if it doesn't exist, you're out of luck because I don't plan to add the ability to create proprietary metadata in video files (video metadata in general is a big mess, and proprietary metadata is next level, so the pain-to-gain ratio for doing this would be much too high).

I think the simplest way around this would be if Catalyst could add the ability to input an FNumber for manual lenses.

As you suspected, FNumber is missing from the timed metadata.
It's also missing Aperture value, although this does not look like it's part of the time series.

All good. I've reached out to Catalyst team. Hopefully they can address this.

Hi,
I am using exiftool to write A7M3 MP4 Metadata in a CSV file for DaVinci Resolve. I noticed that ISO value is a rtmd value recorded every 40ms (1/25FPS). So, I get hundreds times ISO value in the CSV file. Is there an option to write only once ISO value in the CSV file ?
Thank you for your help
have a good day

I faintly recall a similar question, maybe the same, some time ago.  But because ISO and GPS are extremely common words here, it's going to be difficult to find.

[Phil Harvey]

If you use the -csv option you will only get one ISO value.

Hi Phil,
First of all, thank you for this tool which is a great help and thanks for responding
I use -csv option but unfortunatly, it doesn't work. It is certainly because I use -ee option to get information I am expecting. To get some specific metadata, I use join_tags config file you wrote.
In out.csv, you will see that I get many ISO value and "SourceFile" tag at the end.
I tried outputting in txt format with -w! option. It was the same for ISO but "SourceFile" tag dissapeared.
Have a good day

exiftool_Sony.bat
join_tags.config
out.csv
Sony_7M3_1.fmt   

[Phil Harvey]

You are not using the -csv option.  You are using -p.  These options are mutually exclusive, and the -p overrides the -csv.

I was using -p option with an fmt file to "translate" Sony tags to DaVinci Resolve tags.
When I remove -p option, it works but is there a way to rename Sony tags to DaVinci tags ?

[Phil Harvey]

The only way I can think of doing this is by creating simple user-defined Composite tags which are based on the other tags bug have the names that you want.
