Video filter Logo
The Logo filter can be used to place a single bitmap on top of the video.
Bitmap format
Use a bitmap in JPEG format.
The filter description says Add a png as logo, however when a PNG is used, it causes odd scanline artifacts.
Photoshop CS3 (Windows) does not save in the correct JPEG format for Logo, loading one of these causes this error message:
Wrong Colorspace Only YV12/I420 or YUY2/I422 JPegs are supported.
XnView (Windows) does save the correct JPEG format for use with Logo.
Transparency
Logo does not support alpha transparency. The Alpha value is an overall transparency control… 255 is fully opaque, 0 is completely invisible, and values in between cause the bitmap to be partially transparent. The blending uses linear interpolation.
