Is there a video trimmer and auto-joiner for Windows which does not re-encode?

Osama Javaid September 17, 2010

Is there a free software for Windows, similar to solveigMM AVI Trimmer,
which can cut out several portions of any video file with very precise specified timings, joins the rest of portions automatically, and export final video without the slow process of ‘re-encoding’ ?

The above mentioned software has a good feature of not re-encoding the output video but it only supports AVI files and also it is not very precise in cutting the portions specified.

    Try virtualdub

    ---Cutting and Trimming Video
    1) Launch Virtual Dub by clicking Virtualdub.exe in the virtual dub folder. Click File > Open Video File and open the video file you want to cut. If any errors come while importing just click OK
    2) Now we need to set starting and ending points. Scroll through the video scroll bar and stop the the frame you want to start cutting and then go to Edit > Set Selection Start (Home), next scroll to the ending frame of the video you want and select Edit > Set Selection End (End)

    ---Exporting The Video Without Re-Encoding

    1) To export the video without any type or re encoding we need to make audio and video direct stream copy. Click Video > Direct Stream Copy and Audio > Direct Stream Copy. This will ensure none of the streams are encoded and are directly copied as it is.
    2) Now you just need to click File > Save As Avi (F7) and export. It will instantly save it without any type of recompression.


    Avidemux is easy to use and stable in performance, with support for most video input formats like AVI, FLV, MOV, WMV, ASF, MKV, MP4, VOB, MPG and output formats like AVI, FLV, MPG, MPEG, M1V, M2V, MP4, MKV and OGM.

    The following describes how to select the wanted part of an FLV video and save without re-encoding.

    There are two options at the bottom of the window: A and B. You can cut the video by clicking on A to drag the bar to select the start point and B to drag the bar to select the end of the clip. Then, in the left panel, select copy in the drop-down menu of both Video and Audio and select the FLV format in the drop-down menu of Format. In this way, the video and audio streams will be copied and you will save the trimmed video and audio without re-encoding.
