Inzwischen gibt es auch die Dokumentation zu der neuen Funktion im Tiny Media Manager. Die Einstellungen findet ihr unter Allgemein / Seitenverhältnis erkennen.

Aspect Ratio Detector
tinyMediaManager can automatically detect the "real" aspect ratio of movies or TV shows. Many video files are encoded in 16:9 (1.78:1) aspect ratio even if the production was shot in a wider format (e.g. widescreen 2.40:1). In this case the video file includes black bars above and below the actual image. Without aspect ratio detection the video resolution and aspect ratio of the encoded video are included in media information data instead of the real values.
By using the aspect ratio detector feature tinyMediaManager will scan the real image area and will include the aspect ratio and the size of the cropped image (excluding black bars) in the media information.
Aspect ratio detection can be started in the edit module (Media files -> Detect aspect ratio) or in the context menu of the movie panel (Enhanced editing -> Detect aspect ratio of selected movie(s)/TV show(s)/episode(s)). Detection of video files in the .iso format is not possible.
To use this feature FFmpeg must be enabled in the System Settings.
-
Detection Mode: To speed up detection several short samples of the video are analyzed (instead of scanning the complete video file). The samples are distributed over the video duration. If only few samples are analyzed and these samples contain dark scenes the detection might be less accurate.
- fast - Only few samples are used. Less accurate detection.
- default - More samples are used. Very good detection for all movies that do not have multiple formats.
- accurate - At least 30 samples are used for detection. This is needed to detect multi format movies. This mode takes more time.
-
Round detected aspect ratio to: The calculated aspect ratio is rounded to one of several user-selectable industry standard aspect ratios. You can limit the number of aspect ratios that will be used by deselecting the ones that are not relevant.
- Round to nearest aspect ratio - The detected aspect ratio is rounded to the nearest aspect ratio that is selected.
- Round up to next wider aspect ratio - The aspect ratio that is detected is rounded up the next wider (bigger) aspect ratio of the selected aspect ratios.
-
Detection of multi format videos: Some movies have more than one aspect ratio: e.g. some scenes were filmed in 16:9 (1.78:1) format while others were shot in 70mm (2.20:1). You can choose how multi format videos should be detected. For a reliable detection more samples need to be analyzed. Detection of multi format videos is only available if accurate detection was selected.
- No - Use the aspect ratio that is most frequently found. This will also be used if fast or default detection modes are selected.
- Yes, use higher aspect ratio (e.g. for TV or 16:9 projection) - Multi format movies are detected. The higher (narrower) aspect ratio (with the smaller aspect ratio value) is used. This is useful for TVs and projection on 16:9 screens: A scene with a "high" aspect ratio should fill the complete height of the screen. You will see format changes during the movie. Black bars will appear at the top and bottom in "wide" scenes. The complete image content is shown, and nothing is cropped.
- Yes, use wider aspect ratio (e.g. for 21:9 projection) - Multi format movies are detected. The wider aspect ratio (with the bigger aspect ratio value) is used. This is useful if you project on a 21:9 screen and you do not like to see any black bars: The image should be zoomed to fill the complete width of the screen. To avoid projecting "high" aspect ratio scenes outside of your screen the areas above and below the screen should be masked in the projector. Then you will watch a wide screen movie with a constant aspect ratio and without any format changes. But you will also miss some image content at the top and bottom in "high" aspect ratio scenes since this is cropped. This is how many movie theaters present multi format movies.
