Hi. This is on latest macOS (Ventura) with gpac/mp4box installed via home-brew.

I’m needing to create HEIC images from source animation frames and depth buffer produced by Mandelbulber (see attached images) for Apple Object Capture.

For my initial testing I converted the png’s to HEIC using macOS Quick Action —> Convert.

I’m using. …

`mp4box -add-image frame_0000000.heic:primary -add-image frame_0000000_zbuffer.heic:depth:ref=auxl:1 -ab heic -new img.heic`

But get error …

```
No sample found for requested time

	Error: Bad Parameter
```

I’m aware that I could make a lossless HEVC video from my source animation frames, one for the colour images and another with the depth buffer frame (just trying to avoid that step to keep things simple).I’m not familiar with HEVC. Would I be able to make lossless video that would retain all the source image data ? Otherwise is it possible to define the use of a still image frame file for mp4box ?
