I have been running into some unusual results trying to understand how to use Voukoder and Voukoder Pro properly to render out small videos for overlays and lower thirds. Here is a short video that demonstrates what I am seeing. I am probably missing something as I am not fully up to speed on what to look for.
I also tried rendering this small lower third using the stock Apple ProRes preset in Vegas Pro 21. I needed to change the profile to 444 in order to enable selection of the alpha channel but it worked. I was concerned about the reported 1GB file size but after rendering is was around 50mb which is more manageable.
Thanks for these amazing tools and I much appreciate the help in understanding how to make the most of them.
Joyfully,
Simeon
