Preview does not work

[QuarkZ26]

Problem Description

When trying to use preview, it encodes, but then the window is grey. Using external players (VLC, MPC) is the same, no video showing at all. I tried different preset H265/H264 but they all yield the same result.

What version of VidCoder are you running?

7.15, latest beta has the same issue

Try it with HandBrake. VidCoder uses HandBrake for the core encoding engine, so if the issue reproduces there it's an issue with their code and you can ask them for help. If it doesn't reproduce with HandBrake, we know it's a VidCoder issue.

Equivalent versions: VidCoder Stable ↔ HandBrake Stable VidCoder Beta ↔ HandBrake Nightly

[QuarkZ26]

It does work in Handbrake.

I don't see anything obviously wrong in the encode log. Does the issue happen with the built-in presets? Is it a problem specifically with a certain source file? If so can you provide a clip that reproduces it?
