Options

Each of the preset has a number of options, in the panel directly below the preset listing:

Lets take a look at the options, one by one.

1. Video Settings:  The first dropdown you see, which in the picture above says "Recompress video" lets you decide what you want to do with the video.  Here you choose format you want to convert video into.  Click the Settings... button to see the settings dialog for the chosen compressor.
   
   In the dropdown, you can choose to:
   1. Recompress video: (the default) Stomp will extract every video frame from the source movie and recompress it using the applied video settings.  In other words, it'll process the video.
   2. Leave video untouched:  Stomp leaves it along and just copies it to the output video.  The video media is not touched at all. This is like a "pass through" where the source video is simply replicated exactly in the output movie.
   3. Remove it:  The video track is dropped from the output movie.
2. Audio Settings: This second dropdown is similar to the first but applies to the audio portion of the movie. Again you can choose to recompress it to a different form (PCM to AAC, for example), pass it through or remove it.  This option has a few helpful common presets.  Click the arrow button to see these and a dropdown menu will appear.
3. Use video fps of source movie: This is really useful for batch operations. It makes the destination FPS the same as the source FPS, for each movie that's processed.  Normally when you setup compressor settings - you also provide a frame rate (such as 30fps).  But sometimes you don't want to change the frame rate of the movie at all, you want to leave it as it is.  This option lets you do that without having to mess around with your video settings for every movie that you process.  If you enable this option, then Stomp will override the output FPS for each video so that it matches the FPS of the source / input video.
   This option will only work with QuickTime compressors - see "Specialist" below.
4. Change aspect ratio: If you want or need to modify the width/height ratio of the output movie, you can do that here.  The drop down lets you choose from some common ratios. The output movie is then adjusted so that it's aspect ratio matches the setting here.
5. Change video size: This is how you scale a video. You can either enter in an absolute size, or a relative percentage.  The size button to the right can be used to setup either dimension to be a ratio of the other. For example if I wanted to resize so that the video was 16/9, I could choose the Size | Adjust width | 16:9 of height option in the drop down.  
6. Keep aspect ratio: Part of the above option. When you resize a movie, you've three options, which are depicted below. In the example pictures below we've resized a 960x540 movie to 640x900 (from a 16:9 ratio to something very close to 3:4).
