So given the fact qp=4 is true lossless encoding, I'd say qp=4 is the way to go.

There is no "better quality" than true lossless.

Release 13.4

Make sure you are using the latest connector for your application(s). For using NVENC (SDK 12) encoders driver version 531.61 or later is required.

Fixes / Changes

• Using FFmpeg 6.0 build 20231221
• Added cutoff frequency to aac and libfdk_aac
• Added minrate and maxrate parameters to x264 and x265

Just select the correct frame rate in Adobe Premieres video settings.

Happy holidays and a happy new year 2024 to all of you!

With VEGAS Pro this is a bit tricky. I guess you have to click the disk icon to save your preset again after you've made your changes.

I'm investigating this again.

Edit: Both AAC encoders get the option to override the cutoff frequency in the next release.

This has to be manually updated and maintained here: https://github.com/Vouk/voukoder/…s/hevc_amf.json

I don't have an AMD GPU for testing. They promised to send me testing equipment, but unfortunately they never did.

Feel free to update the AMF files, it's an open project.

Yes, it is possible once I add the minrate and maxrate parameters to the options.

Edit: Will be in the next build!

What player do you use for playing that file?

Thanks for letting me know.

It really sounds like there is a QT specific issue. I don't set the Track-ID / Stream-ID manually. But the order shouldn't matter at all. Can you send me a small sample file so that I can investigate this as well?

Version 0.9.1 introduces first "Chapters from Markers" support for DaVinci Resolve Studio.

I'd like to, but it's difficult to find information about it. As far as i know FFmpeg contains an IMF demuxer, but not a muxer. The images themselves seem to be JPEG2000 encoded. Do you know if it is possible to create an IMF file with FFmpeg?

I have checked it. These are the currently available values:

FFmpeg: libavutil/pixfmt.h File Reference

Version 0.9 should bring a drastic performance boost with CPU based encoders (i.e. ProRes).

No, Voukoder is using the encoders from the FFmpeg project. They have CPU ProRes only.

What version of VoukoderPro and After Effects are you using?

3840*2160/2560*1440=2

It doubles the amount of work.

These are the options I have available:
