Can you try VoukoderPro 0.7.8 and/or connector 1.7.1 if this helps?

It looks good on my side. I can import the created files with VEGAS Pro and DVR and they have an instant transparent background without the need to configure anything.

Can you send me an example project how you check this? Maybe that helps me.

But is transparency possible? Any experiences?

You need to disable audio in the NLE. Then it should be visible.

I'm not sure this is possible at all. The pixel format (rgb8) supplied to the gif encoder does not contain an alpha channel.

Encoder gif [GIF (Graphics Interchange Format)]:
    General capabilities: dr1
    Threading capabilities: none
    Supported pixel formats: rgb8 bgr8 rgb4_byte bgr4_byte gray pal8
GIF encoder AVOptions:
  -gifflags          <flags>      E..V....... set GIF flags (default offsetting+transdiff)
     offsetting                   E..V....... enable picture offsetting
     transdiff                    E..V....... enable transparency detection between frames
  -gifimage          <boolean>    E..V....... enable encoding only images per frame (default false)
  -global_palette    <boolean>    E..V....... write a palette to the global gif header where feasible (default true)

I might have missed this, sorry.

In DVR you can select the format and resolution how the frame data is sent to Voukoder(-Pro). Voukoder itself then does the conversion to the desired output format. To my knowledge ProRes does not support 12/16 bit data, but other codecs like i.e. FFv1 do.

Schicke es mir (oder je nach Größe einen DropBox o.ä. Link) an daniel@voukoder.org.

Kannst du mir ein kleines Beispiel-Projekt mit den Audio-Spuren schicken damit ich das genauer untersuchen kann?

1. Hast du beides installiert?
   
2. Hast du den Connector nach C:\ProgramData\Blackmagic Design\DaVinci Resolve\Support\IOPlugins installiert?

It should be present in Voukoder classic.

But I've also added it to VoukoderPro in version 0.7.7.

Added the potential fix also to the VEGAS Pro connectors 1.7.0 for Voukoder classic.

Can someone please try if the alpha channel now works with version 0.7.6 of VoukoderPro?

I reinstalled the voukoder.org webserver and updated all software components to the latest version.

Let me know if there are any issues.

Voukoder is for Windows only.

VoukoderPro - once it is finished - can be also built for Mac.

You don't need to worry about the hardcoded settings. They match up with the encoders default settings (on the command line).

Are you sure you want to encode in 10 bit and not 8 bit?

It'd help to use a faster preset. p2 and p1 would even use both encoding engines of the 4090.

For some reason the cpu is the bottle neck here.

vRender (The time premiere needs to render the frame) is constantly changing between 0.2 ms and almost 700 ms. What's your cpu doing?

Okay, I improved it even more. You can now even execute JavaScript in the file name using

${...}

So you'll have all the freedom you want for dynamizing your filename.

Improved this a bit more.

Great! Nice to hear!

Found it. For the hwupload_cuda filter the parameter name is device not gpu. Fixed it in 0.7.5.

You might have to edit each hwupload_cuda node, select the gpu and save the scene again to make it work.
