Alpha channel and Roland V1 HD

Hello,


For our live streaming we are using a Roland V1 HD. At the moment we use a copy of the front of house signal(see picture bottom left) and we key out the black to overlay the text. But it would be much easier if could you the alpha channel function for this. So we are testing with that. But the output from the alpha channel shows very 'blurry' text(see picture bottom right).

Does someone knows how to fix this?


That is the alpha key. You have to create either an upstream key or downstream key for it. I have not used the Roland V1 HD so I wouldn't know exactly how to do it for that.

After googling it, it looks like it might be in Effects.

I found a fix to this one. I am using the same ROLAND VR-1HD and it was blurry for alpha channel. Email me at [email protected] if you still need the fix.


Thanks

Hi, I am also struggling to find a way to fix the blurry alpha channel. Can you help me check a bit? I have emailed you. Many thanks!

Ensure that the resolution of your overlay (text with alpha channel) matches the resolution of the video feed. If there is any scaling occurring, it can lead to a loss of sharpness, causing the text to appear blurry. Make sure that: The resolution of the source text is high enough for the video output.

The resolution settings on the V1 HD are consistent across all inputs and outputs. Alpha channel information is stored with varying bit depths (8-bit, 16-bit, etc.), and if the bit depth is too low, it can cause artifacts such as blurry edges. Make sure that the alpha channel is being processed at a high enough bit depth for clean edges.
