UPDATE 2/17/12: Solveig Multimedia has released version 3.0 of their software. Read the review I did here.
There are a lot of good MVK muxing/demuxing softwares out there. Unfortunately, there isn’t a ton that let you edit/trim MKV’s visually and accurately without rencoding (which creates quality loss) like VideoReDo or VirtualDub do for MPEG’s or AVI’s. This seems due to the way key frames are set in the H.264 format.
Most searches for “trim MKV”, “split MKV”, or “edit MKV” lead to Avidemux or MKVtoolnix. While MKVtoolnix for Windows gets you MKVmerge GUI, it can only split at specified time, size, or time code intervals. I was looking for a visual editor.
AVI Trimmer + MKV 2.0
I finally found one solution that is free. I never tried any of the paid software that claims to edit MKV’s. AVI Trimmer + MKV 2.0 was created by Solveig Multimedia. It allows you to trim MKV’s using a GUI interface where you can drag the sliders and see exactly where in the video clip you are. Did I mention it’s only 9MB small?
I have tested it with a few formats and it seemed to handle any codecs that were currently installed on my system (using Haali Splitter for video and AC3Filter for audio). The sample video file I tried was encoded at a resolution of 720p and the audio was DTS. I was able to split at any millisecond I wanted and the final file played flawlessly.
There are 2 things I wish AVI Trimmer + MKV 2.0 had:
- Ability to save a project (this can cause issues because it did crash once)
- Step button to advance the video frame-by-frame (you can however type in the timestamp manually by milliseconds for exactness)
There were a couple quirky things about the program:
- If your first clip includes the first frame, you have to push the first frame button, or it won’t add that clip to the timeline (fragments) to save.
- The program started on top the visual editor (top left) so I wasn’t aware of its location. I just had to drag the main program window out of the way to see it.
- There are only 3 almost useless options: Autostart scene detection, Confirm adding overlapped fragments, and Show hint after adding new interval
Overall, I have to give the developer a serious thanks as this does one simple job very well: trim MKV’s without re-encoding. I been looking forever for something similar to VideoReDo for a long time for MKV’s. Let me know in the comments how it worked for you.
