    Overlay on recorded video

    Is it possible to create an overlay while capturing/recording a video?

    I want to add some text to the video while recording and save the file to the isolated storage.

    Yes it possible to show overlay while capturing/recording video,

    you just need to define overlay control at any position you want for e.g. You are showing your capturing frame in 0th grid row then just show indefinite progress bar(i suppose overlay) in same row.

    <Grid>
    <Canvas x:Name="LayoutRoot" Background="Transparent" Grid.Row="0" Opacity="0.5">
    <!--This is camera capture windows -->
    </Canvas>
    <ProgressBar Grid.Row="0" IsIndeterminate="True"/>
    </Grid>

    Re: Overlay on recorded video

    nearly answered excatly the same, anyway, I suppose the question is to record video, and embed stuff into the frames in it, so the video itself would have the overlay, and not the viewfinder. Anyway, last time I checked the video recording, I did not see anyting which could be helpful for the purpose.

    Nope that is not possible. I've been looking at that also, to include simple text and such, and there seems to be no way to do that. You can do that with photography because you can actually have a vewfinder o your own app and then when the picture is taken add affects and changes to the file. In fact you can even do that while capturing the photo. But there is no way to do that with video.

    Only option is to encode video manually, for that you need to compile some encoding library (x264 or ffmpeg or whatever) and then get raw frames, modify them and give to encoder.
    This is technically possible on WP8, though compiling the encoder is a hard part

    That is the only possible way to do that. No out of the box workaround.
