You may want to do away with those annoying advertisements in between your favorite recorded TV shows or explicit scenes in a movie not suitable for family viewing. The following three guides will show you how to remove commercials or other unwanted scenes from MPEG files without hampering the audio or video quality. If your video is other format,  like AVI, ASF, RMVB, WMV etc., you can follow guide 2 to delete ads or unwanted footage which will need re-encoding your video.

Tool: MPEG Video Wizard DVD

MPEG Video Wizard DVD is a frame accurate MPEG editor which comes with DVD authoring and full AC3 audio support. It is nice, especially for those capturing MPEG with ATI or Hauppauge cards, or from files made on DVD recorders. It will edit MPEG files without degradeing the quality at all. It’s not freeware, but don’t worry because you can try it for a month. You can free download it from here

Now start the program and let's begin´╝Ü

Guide 1. Remove commercials from MPEG files with the blank fades search function

Step1. Drag your video file from its folder into the "Input" monitor.

Step2. Right click in the input monitor and select "BookMark Browser" from the context menu. This will bring up the bookmark browser window.

Step3. Press "BlankFades" button in the Bookmarks window to search the blank fades. When it is done, you should have quite a few "bookmarks" of scenes where fades have been detected. We will then drag the video onto the timeline using the "Drag" button – just click on this button, hold it and then drag it onto the timeline's video track (the top most track). You can now close the Bookmark Browser window.

Step4. Notice now on the timeline the many sections where the BlankFades function divided the video whenever there was a fade. You can double click on each section to play the video in the "Input" monitor and make sure it is a commercial break. Make sure to check any small segments just before and after, as these may be part of the commercial break too.

Step5. To delete the commercial breaks, simply click on the section you want to delete and press Shift+Delete key combination to remove it (or right-click on the commercial break, select "Shifted Delete" from the context menu). Repeat this for every commercial break.

Step6. Preview  the output to make sure everything is fine by using the playback controls in the "Output" monitor.

Step7. When you're done, click the red dot button export button on the timeline. In the Save As window, type your file name, select Automatic as file type, and then click Save to export all the clips to a new MPEG file. To check if your video needs re-encoding, click on the Detail button, which opens up a new Export MPEG detail information window – the blue area shows the part of the video that won't need re-encoding (stream copy), the red areas is the parts that need to be re-encoded. See the screenshot below, we will export all the clips to a new MPEG file without re-encoding.

Guide 2. Edit out unwanted scenes with the split function

Step1. Drag your video file from its folder onto video track (the top most track) of the timeline.

Step2. Drag the edit line to navigate through the video on the timeline and preview it in the output window. Drag the edit line to the start of unwanted scenes – you can zoom in and/or use mouse wheel / arrow keys to find exact spot, and then press the split button on the timeline. Then locate the end of the commercial break in the same way and split again.

Step3. Click on the section you want to delete and press Shift+Delete key combination to remove it(or right-click on the unwanted part, select "Shifted Delete" from the context menu).

Step4. Repeat 2 and 3 for all unwanted parts, then preview  the output to make sure everything is fine by using the playback controls in the "Output" monitor. When you're done, click the red dot button on the timeline to export all the clips to a new MPEG file.

Guide 3. Delete unwanted footage from MPEG files with the cut function

Step1. Drag your video file from its folder into the “Input” monitor.

Step2. Find the beginning of the unwanted segment by dragging the timeline slider and press the Mark-In button.You can use the mouse scroll wheel to step forward or backward to get the exact frame. Then move forward to find the end of the unwanted scene and press the Mark-Out button. Now press the Cut button to cut out the marked segment.

Step3. Repeat 2 for all unwanted parts. At this point, you may want to check your editing result by opening the Property display window, which is accessed by right mouse clicking in the "Input" monitor and selecting "Properties…" In this window, you can see a small map of segments for the current playback list. The solid blue colored areas are the segments remained; while the other ones are the segments being cut.

Step 4. Now, the video in the Input monitor are only the segments of the show, and we are ready to save it into a new MPEG file. Press 'G' on the keyboard to add the list of the segments into the timeline. Then preview  the output to make sure everything is fine by using the playback controls in the “Output” monitor. When you’re done, click the red dot button on the timeline to export all the clips to a new MPEG file.

Done.
