Review comment (refactor):
The `timestamp` code seems now pretty difficult to read. I'd like to simplify the entire return block using `traverse_obj`
```py
        return {
            'id': video_id,
            'display_id': display_id,
            'title': self._og_search_title(webpage),
            **traverse_obj(post, {
                'title': ('post_title', {str}),
                'description': ('post_body', {str}),
                'tags': ('post_tags', {lambda x: x.split(',')}, ..., {str.strip}, filter, all, filter),
                'channel_id': ('user_id', {int}, {str_or_none}),
                'uploader': ('user_name', {str}),
            }),
            **traverse_obj(content, {
                'url': (('secure_url', 'url'), {url_or_none}, any),
                'timestamp': (
                    ((('start_date', 'crdate'), {parse_iso8601(delimiter=' ')}),
                    ('created_at', {parse_iso8601})), {int}, any),
                'duration': ('duration', {float_or_none}),
                'categories': ('category', {str}, all),
                'cast': ((
                        {value(post.get('user_name'))},
                        ('guests_json', {json.loads}, ..., 'name'),
                    ), {str}, filter, all),
            }),
```
