Quick start-up guide:

1. Select job type

2. Add source files

3. Modify stream parameters.

       - "Enable" checkbox - means that the stream will be present in the output file

       - "Copy" checkbox - stream will not be reencoded, only copied, so, stream options (lower part of the app) will be disabled. To modify stream just unckeck it and you will be able to choose codec and various audio / video options.

      - To enable Picture settings on a video stream (crop,   pad , rotate, etc) first, you need to uncheck "Copy" and click the video screenshot or just click on Picture Settings button. Options seted here will be automatically saved when you close this window. If you reopen "Picture Settings" later all settings for that video stream, now, will be preserved.

4. Hit "Run now" button to start conversion. The application will ask you for an output file and depending on the file extension chosen will use the proper format (container). i recommend Matroska (.mkv)  because it is compatible with all the codecs available in the app.

5. Sit back and wait for it to finish. What you see in the Output tab is exactly the ffmpeg output. You can approximate the progress by looking at the written time (100% = source file duration).

Use stream profiles:

  1. create - You are able to create a new stream profile only in convert mode but you can apply them for different job types. So, first import a file and unckeck copy. Then make desired settings and from Main Menu : Profiles - Add, choose a profile name, just make sure it is a meaningful one. That's it. You must create different profiles for audio and video. A video profiles also stores filter settings (Picture Settings). Using profiles is the only way to apply video filters in bulk mode.

2. apply - Just right clik on audio or video stream settings panel and apply desired profile.

3. delete - From Main Menu choose Profiles - Delete and pick the your desired stream.

Use Bulk mode:

 Let's start with an real example: Extract audio from Youtube videos and convert them to mp3s (mp4 to mp3).

1. Select Bulk mode and drag and drop your files.

2. From bulk mode set Video to "None".

3. Set Audio to "Audio Tab" and then press audio tab and choose mp3 encoder.

4. From bulk tab again choose container mp3 and select an output directory. That's it. Press Add Job and click Start.

Here is another option: nth which means to extract only the nth audio stream form the file. It is useful when exporting to containers that accept only one audio stream and source files contains multiple tracks.
And another new one: If you want all output files to have normalized audio streams then check AG. If you adjust the gain level from the Audio Tab, then a correction will be made to the automatically detected sound level, essentially raising or lowering the normalized sound of the streams by a specific amount.

Create video from images:

dmMediaConverter can create vireos form images using version 2.4.5 and up. It is a very simple trick. Use Merge different mode and add all your images in the desired order. Then, press More button and in Other in put "-loop1 -t 2" without the quotes. 
Change -t value for another image duration in seconds.
Choose encoding options and hit Run Now. ;)
