some transcoded videos are corrupted when downloaded

### I have searched the existing issues, both open and closed, to make sure this is not a duplicate report.

- [x] Yes

### The bug

I tried to send and embed a video to discord and I noticed that it stopped playing after a few seconds, so I downloaded the video with wget and tried to play it. media player couldn't play it for more than a few seconds either. I also tried to re-encode it with ffmpeg but it found the file corrupted.

I tried to encode them with vaapi as well, but it resulted in corrupted files as well.

the videos play in the browser fine, both in the immich library and from a shared link.

here are the original and transcoded videos, as well as immich config file:

.env for the video transcoding server has  DB_HOSTNAME, REDIS_HOSTNAME and IMMICH_WORKERS_INCLUDE='microservices' added
```

### Reproduction steps

0. have my hardware and setup
1. transcode a video
2. share it (I'm not sure if this step is necessary)
3. download the transcoded video
4. try to play it

### Relevant log output

I don't know if this is relevant (it happened only once but I have tried transcoding and downloading multiple times):
```shell

```

no errors on the transcoding server, just normal output. example:
```

```

### Additional information

when using vaapi with a particular video, nothing past ~1 second mark played. with software transcoding, it went up to ~7 seconds. curious, huh?
