Checkerboard for Alpha, someone will need it

Can you guys add Checkerboard or Transparent Background to see if The video has alpha or not thank a lot, cause i alway to put my video in AE to see it!

Have a nice day team

You can use the MediaInfo tool from the pack to see if a video has alpha channel.

Look at "Chroma subsampling" value. For most videos it will have value 4:2:0. The last number is for alpha. So no alpha for those videos. YUV colorspace does not have alpha.

When video has alpha channel it has value 4:2:2 or 4:4:4. But even then it can be non-transparent. But you would only have to check those videos.
