FR: Save images to predefined folder

[gerroon]

Hi

it would be great if one could just capture individual frames to a predefined folder like that can be done with VLC. It isa bit tedious to constantly enter individual file names for saving single frame.

I've added File->Save->Frames to Folder to v0.9.4 beta currently on sourceforge.net (https://sourceforge.net/projects/mrv2/files/beta/).

The first time you call the function, it will ask you the parameters and the directory and name to save the file as usual. However, the next times you invoke it, it will automatically save the image without popping any options or file name.

To change the file name or options that it is saving under, you should go to File->Save->Single Frame as usual and then go on to keep using File->Save->Frames to Folder.

Thanks, it crashed when I did not provide a file extension.

How do I set the actual frame number?

Also it keeps opening the folder browser, then I am manually saving every time I pres "alt-s" which I set to be save single frame. I do not see it saving in hte background like VLC does.

Just save a filename like test.0001.tga or test.0001.exr. Just test.exr should work too (it will be renamed as test0001.exr IIRC). If you have a movie file, you may need to set Annotations to on to save EXRs.

The number will be added automatically based on the frame you are in. So, it won't save them in sequence (like 1,2,3,4), but with the original frames, which I think is more useful.

It does not work on Windows 11, as far as I can tell.

Exr trows error

ERROR: [save] D:/.TMP/test.0001.exr: Unsupported video

As you see the frame number is not saved

This is the error you get when you don't have Annotations on. Movie files are encoded in 8-bits YUV which EXRs do not support. Turning ON Annotations on makes the frame be captured in RGBA_F32 which is compatible with EXRs.

Thanks, I'll check that, as it is likely a bug.

I checked both File->Save->Single Frame and File->Save->Frames to Folder. With either one when I save with no extension, I get the following error:

ERROR: [cback] File extension cannot be empty.

You will need to give me step by step instructions to reproduce it.

You should not set the shortcut to "Save Single Frame" (which does exactly what it says it does), but to "Save Frames to Folder".

Thanks for the addition, that was it.
