It seems AfterEffects does not render the frames fast enough, so using GPU acceleration in this case does not make sense. The necessary RGB->YUV conversion slows it down too.

Technical info about this: https://www.voukoder.org/forum/thread/352

Ich würde den Bug schon gerne behoben, den das könnte auch bei anderen Usern auftauchen. Vielleicht findest du ja noch raus wie man das reproduzieren könnte.

Wegen den Formaten mach doch bitte einen Feature Request auf mit den entsprechenden encodern und muxern. FFmpeg kann viel, aber da sind auch echt antiquarische und exotische Sachen dabei.

I am in contact with a big company right now to include voukoder also in their product(s). I really want to keep the configuration independent from the host application. So going back to the version 1 style is not an option.

But I am also thinking about this for many months. I'd like the user can chose between a very simple interface and an advanced interface. I am open for suggestions and concepts that satisfy the needs of users with less encoding knowledge and pro users that want to optimize each single option.

Still ...

• The whole UI has to match the technical requirements
• It has to be compatible with wxWidgets 3.

The plugin would actually be the same. No matter if you use the installer or a manual installation.

Please see the comment above and provide this information. I could not reproduce it.

I am not able to reproduce it. Does anybody else have these issues?

What dropdown boxes do you mean? Can you provide steps to reproduce the issue?

This way it worked.

1. Created new project with 60fps

2. Created new composition.

3. Added Composition to render list

4. Selected target file

5. Configured Voukoder video settings

6. Started Rendering

Can you add more details on how to reproduce it and provide a screenshot of the whole render list?

Is fixed in the next version.

Kannst du mir die genauen Schritte nennen um den Fehler zu reproduzieren?

This is fixed in the next release.

This is most likely a bug. I'll investigate it ...

Die YUV420 10 Bit Sache ist in der nächsten Version behoben.

Bitte mache jeweils einen Thread pro Thema, bzw nutze die existierenden Themen.

Unfortunately I can not fix it until Adobe has told me how to do it.

Das ist so nicht korrekt. Im Gegensatz zu anderen GUIs verwendet der Voukoder keine binaries (wie z.b. x264.exe sondern nutzt direkt die C API). x264 erkennt das dort anhand des übergebenen Pixelformats:

Es hat sicherlich eher mit der Kombination der Parameter zu tun. Kannst Du mir bitte mal Dein komplettes Log nach Reproduktion des Fehlers schicken? Dann sehe ich mir das an.

Did not find a solution yet. I close it until there is a way to do this with the ffmpeg / libav.

Will be back in the next version.

Will be available in the next release.

Zitat

• Voukoder does not necessarily do exports faster! It simply provides access to different encoders. These give you the possibilities to choose between the three encoding priorities. Encoding speed or video quality or filesize. You can't have all together!
• Voukoder does not speed up rendering! If the host application is slow with rendering / delivering frames Voukoder can't make it go faster and it is actually limited to that speed. No matter how fast any encoder / GPU is!
