Movie record and layer masking

Support
1

I don’t know if this is a bug or something I haven’t run into before. But basically when I try to do a movie record of the main output it will disregard any alpha.

My setup.
Main Output
Video Layer (to which I’m applying another layer as a mask)
Masking Layer (hidden 0 opacity)
Masking layer 1
Masking layer 2

I’m using two masking layers with a two channel mixer for a smooth fade in fade out.
The video layer is using the Masking layer (group) as a masking layer. The desired affect is achieved and it can be viewed on the main output.

The problem occurs when I try to use Movie recorder plugin to capture the Main output. Instead of having an output with the layer masking applied I get a clean Video layer output as if there was no masking. I have tried to record in other formats that will allow to record alpha and at that point the output does show the masking.

Is this expected behaviour? And how to record what is seen on screen?

I have set all layers to SourceAtop.metal.

Hi @Jernej,

A few questions.

  1. Which version of VDMX are you using (VDMX5, VDMX6, and what version number?)
  2. Do you have an alpha channel set on the movie recorder, and what codec are you recording to?
  3. Can you make a video of what you are experiencing?

  1. I’m using VDMX 6 Plus build 1.2.1
  2. this is the issue, with h264 I cannot select the alpha channel. Using HAP codec with alpha creates a correct recording.
  3. I have created two video videos, one captured with the movie recorder plugin and the other with quicktime. You can download them on the this link, it will expire on the 25.9.

I have found a workaround and it is to create a black solid color layer to put underneth all the visible layers. I do not remember thath being a neccesity before.

H.264 does not support an alpha channel. I believe you can only do this with HAP Q, HAP R, and ProRes.

For the videos you captured. How are they being outputted? Is VDMX capturing from the Main Output or from a layer?

Please share some screen shots of your Movie Recorder settings.

Thanks
