BRAW API 2.0 MultiCard Examples (Dual Recording, half fps)

PostMon Jul 27, 2020 1:34 pm

Hi,

Thank you for the 2.0 BETA of the Blackmagic RAW SDK. I was wondering you would have .braw file examples for Multicard .braw shot through the new Dual Recording feature of the URSA Mini Pro 12K ? This way we'll be able to test this new feature and integrate it into our Adobe CC importer BRAW Studio.

The following method are in the new 2.0 SDK and we need to test them properly :
Code: Select all
GetMulticardFileCount Queries how many cards this movie was originally recorded on to
IsMulticardFilePresent Queries if a particular card file from the original recording are present. If
files are missing the movie will still play back, just at a lower framerate


Thanks,
Antoine

Does anyone have the URSA 12K in beta and could produce a file for us to test ?

Any update on this one ? How are we supposed to support something we can't test ?

I asked for files samples from actual users here : viewtopic.php?f=2&t=130178

Just to let you know how this works, the extra files have a different extension, eg *.braw1 - the intention is not for the user to add these files to an NLE or player etc. You only add/import the normal *.braw files (Resolve etc will ignore .braw1 files and not import them) and in the background the SDK will check the metadata which tells it there should be more multicard files and it will search the same directory for them and handle it all - these will have the same exact filename except the different extension. If no other files are found in the directory, you will get a lower frame rate but it will otherwise work. If you rename a *.braw1 file to something else and change the extension back to regular *.braw file it will also play at a lower frame rate but otherwise also behave as a normal clip.

So devs shouldn't really have to do anything to support these files as the SDK will handle it and "present" them as normal clips. Once the holidays are over I will try organize some test clips though.

Also FYI, if you use the "trim" function from the SDK it will combine these files into a single file/clip (you don't actually have to trim away any frames).

Thanks for the description it is very helpful. I hope the .braw1 file gets proper metadata so as to be able to match them with their .braw file irrespective of the fact they have the same filename

Happy New Year !
