audio desync after upscaling video with variable framerate (vfr)

[Kuphi]

Version: VideoJaNai 1.1.0

I tried to upsacle videos that are encoded in h264 and have a variable framerate (vfr). The audio is decoupling from the video stream. At the beginning the audio is still fine, but a few minutes into the video there is already a difference of several seconds.

Is it possible to circumvent this behaviour?

P.S.: I would like to thank you for this great app. It is by far the best video upscaler that I've used so far and it's really straightforwards to use. (I'm using it with RealESRGAN_x4plus_anime_6B, which I converted to onnx using chaiNNer. At first I had excess VRAM usage errors, but turning "Use Automatic TensorRT Engine Settings" to No and switching to "Static Engine fp16" fixed the issue. Just leaving this here if anyone encounters the same issue.)
