I am working with a source material from a BMPCC 6K camera that has several media dropouts. I have this bright idea of replacing the "Media Offline" artwork with a "green screen." This would enable me to layer media below, repairing my media issues for delivery.

So does anyone know where this artwork is stored?

Thanks,

These kinds of images can be embedded as resources in the executable files, there isn't necessarily a separate file somewhere that you can replace. I mean, there could be, but it's by no means certain.

If this is not a separate file, typically it is embedded in a DLL. The question is which DLL has this image as a resource.

It's inside resolve.exe, you can use the the following online tool to see all the images of resolve.exe.

The problem is that resolve.exe is protected from modifications.

You're taking something of an odd approach here, George. Seems to me it would be better to solve the actual issue and get the clips fully working.

I am with Jim on this one George. I cant see a single advantage to turning your media offline graphic into a green screen vs simply removing/relinking the offending clip. You would just be using unnecessary processing resources.

Speaking as a coder, when you have a hammer, everything looks like a nail. I saw this as a quick fix for a BMPCC 6K shortcoming.

Making this error into a chroma key would allow an easier workflow for this 17 minute clip with 134 frame drops. I could have an easy time of color grading only two clips, my original BMPCC and the (inferior) MPEG from Adobe Premier.

Sad that artwork is in a protected exe file. Just from a programming and updating aspect it would be better to deliver smaller updates to individual files rather than the whole, thus the argument for delivery of this "stock artwork" in a separate resource.

That would be?

You can also detect these frames by using difference with the media offline image. Any frame where average difference is zero or close to zero, set alpha to 0, for every other frame set it to 1. It could be possible to do it in color page too, but in Fu it is easier.

My New BMPCC 6K dropped out over 140 frames in a 17 minute video. In Resolve the drops appear as media offline. Before you ask I used Certified Media, AngelBird AV PRO CF. These drops started after about 2 minutes.

Do you see them in the camera? If not, your reader might be the culprit.

Interesting, I reviewed the video in the camera and it did "jerk" at the dropped frames but it did not stop or throw "Media Offline" screens. I don't quite know what to make of this as I used both AngelBird media and an AngelBird reader.

Any suggestions would be appreciated.

You didn't turn on the setting to stop recording when frames are dropped?!

Eeesh!

You are kidding right, a 2K $ camera should not drop frames.

Cameras are totally dependent on the media being able to write fast enough to record everything. If the media is slower than the data coming at it then the camera doesn't have a whole lot of choice, it can either drop frames and continue on as best it can or it can just throw up its hands and stop.

There's a related (although dated) discussion here, it might be helpful.

Even an Angelbird device can be faulty.
How was the card formatted?

The card was formatted with exFat.

In the camera?

No, did not find that menu until you asked. Found something interesting, the CF card gets quite warm to the touch, particularly outside here in Texas. I guess it is winter in Australia so they did not test for that

I ran the camera in a configuration close to what produced the dropped frames; outside, Commercial power, two microphones (one with phantom power). I got these results, Resolve Edit shows some "Media Offline" frames but the review does not. In my original video these frames are both in the time line and on the review screen.

Will do more testing to isolate issue.

What kind of CF card is it, and is it certified for use with the camera? Your efforts may be futile if not, and even so it might just be more expedient to get another card that's rated for the required speeds and more, just to be safe.

It is certified, an AngelBird AV PRO CF GB

Definitely do the formatting in the camera.
And then, even an Angelbird can have a broken wing.

So which brand actually meets specs?

All those listed by BM. I just wanted to say that any device can be faulty.
