Alternatively, these settings may be accessed by clicking either the Encoder button on the Video tab or the ‘Advanced’ button on the R hand tab. Since MediaCoder build 5120, the tabs for FFmpeg and x264, opposite the Video tab, offer an easy means of setting the GOP and, if required, the number of B-frames. On the other hand, cutting only at I-frames may be too insensitive (12 sec jumps, say). The Pgm may choose to cut at the nearest I-frame, rather than at the chosen frame, or if it accepts the cut at the chosen site, there may be loss in quality in the vicinity of the cut. On the other hand, a GOP of 250 is a more common and 300 or more may easily arise, which represents at least 12 sec for a file at 25 fps. The number of frames between each Keyframe is the GOP, which is small in the MPEG2 (VOB) files from a DVD (typically 12 for PAL). This arises because the frames between the Keyframes, such as B- and P-frames (see viewtopic.php?f=17&t=8599&start=0), have reduced information and rely on the adjacent I-frames to calculate the missing video data. When cutting a file at other than an I-frame (Keyframe), there may be a local loss in video quality and problems with audio-video sync.

However, if your need for editing is limited or infrequent, a free Video Editor would be ideal, having more than enough features for most users.

Of course, top of the line professional editors like Adobe Premiere Pro can do far more than mentioned above. However, these offer little more than the best of the freebies other than extra effects and transitions. There are also a number of commercial editors for the non-professional, even for as little as $50 to $100, such as those from Zilisoft, VideoPad (Pro version), Nero and Coral, listed from cheapest to dearest. I was also hopeful of finding an Editor that could correct audio/video sync problems by shifting the audio stream relative to the video and/or stretch or shrink the audio track to change its duration (tempo) relative to the video. Some are capable of more, such as adding effects and transitions and doing picture-in picture. This Guide covers those free video editors that are capable of simple editing, such as, trimming the ends of a file, the removal of unwanted, intermediate segments (advertising, etc) and the joining of files/clips. They will most likely work in Windows XP as well - see an earlier Guide at viewtopic.php?f=17&t=8741&start=0.

However, even professional editors are limited in the supported input formats, so, a further conversion in MediaCoder may be needed (see Section 3, below).Īfter a reasonably thorough search in Google during Feb 2012, I have described below all those Video Editors that were then available, are truly free, rather than just free to try, and that worked in Win7, my current system. Maybe even join different clips together. It may also be useful to add special video effects, and transitions at any joins, to make the ‘movie’ more interesting.

Some of these files would have been downloaded or captured from TV or a Camera, and it would be great if we could cut out unwanted segments, such as TV commercials, or tidy up home movies.
