Review comment (suggestion):
This would return `None` for `vcodec` instead of `'none'`.
```suggestion
        return {
            **traverse_obj(entry, {
                'id': ('id', {str}),
                'title': ('title', {str}),
                'url': ('fileUrl', {url_or_none}),
                'release_timestamp': ('episodeDate', {parse_iso8601}),
                'thumbnail': ('featuredImage', 0, 'filename', {str},
                              {lambda x: x and f'https://rinse.imgix.net/media/{x}'}),
            }),
            'vcodec': 'none',
