Virtualdub can be used to transcode MTS AVCHD files to MPEG I-frame HD in an AVI container which can then be imported into Lightworks. (Thanks to chuckzoots for this) Method 4 - Virtualdub It can be downloaded here (Make sure you Download Quickmedia Converter not YouTube converter) I believe files can be queued into a batch and left to process unatended. XMedia Recode is another very good GUI Converter. (Thanks to shaunthesheep and drkuli) Method 2 - XMedia Recode Here is a pdf file showing the settings for all the relevant tabs in the 64 bit version of MediaCoder. Keep the mp4 file for future use when LW's handling of long GOP is improved. If you are importing from an external USB drive best use 50 MB bitrate as Greg_E suggests in an earlier post. There is a bitrate choice of 50 MB-250 MB. In the meantime, if you want the footage to play smoothly in LW, import the mp4 with Lightworks' transcode function using MPEG I-frame HD/AVI. Improved handling of long GOP is on the Lightworks roadmap. The imported footage does not play smoothly in LW but as drkuli pointed out this is very possibly down to LW's current problems with long GOP. These are the steps for the 32 bit version (or load drkuli's preset which does this automatically).Ĭ) In the source drop down menu, select "autoselect", or "MPlayer", or "MEncoder".

This is drkuli's theory about what is happening. 25 fps to 50 fps even though "copy video" is selected on the video tab and "original" frame rate is selected on the picture tab. The only weird thing is that the video frame rate is mysteriously doubled from e.g. LW imports both video and all 6 surround sound audio tracks at the same time from the mp4 file. The resulting file plays in VLC with both picture and sound OK. The video is re-wrapped (not transcoded) but the ac-3 surround sound 5.1 audio is transcoded to aac. To load the preset in MediaCoder go to File > Load presetĮxplanation: the latest versions of MediaCoder are experimental betas and the 32 bit version does not work at the time of writing so use the older V.0. 32 bit version. of MediaCoder (it will be eventually archived at ) and load drkuli's preset. ![]() ![]() People with 32 bit systems download 32bit V.0. To load the preset in MediaCoder go to File > Load preset People with 64 bit systems should download and install the 64bit version of MediaCoder and load shaunthesheep's preset. Our experience has been that while this method generally works with the 64 bit version of Miediacoder it has frequently failed with the 32 bit version because different versions of FFMPEG and MEncoder are installed. Different versions of the back-ends are used in the 32 bit and 64 bit versions of Mediacoder. The problem with Mediacoder is that it is a GUI/front-end for a variety of back-end engines like FFMPEG and MEncoder etc. I attempt to list pros/cons at beginning of section Method 1 - MediaCoder Lightworks can transcode AVCHD QuickTime files on import to MPEG I-frame HD which solves playback problems. Lightworks Beta currently has some long GOP performance problems but improved handling is on the Lightworks roadmap. Smooth playback in Lightworks of AVCHD files depends on CPU. MTS files need to be re-wrapped to mp4 or transcoded to MPEG I-frame HD in an AVI container (there is little quality loss). Lightworks currently supports AVCHD natively in QuickTime containers only (mov, mp4) not MTS containers. ![]()
