"tried a number of converting software". Can you please tell us which transcoders you have used so we don't re-suggest something you have already tried?
When does the "pixelation" happen?
Can you please provide some specs on your Mac? RAM, CPU and available hard drive space are a place to start.
Also, the camcorder manufacturer and model - and ideally, the "video quality" setting" when the video was captured will be useful. As well, the video environment - that is, was there fast action/motion that was recorded?
There is no video editor (Macintosh or other operating systems) that directly edit MTS files of which I am aware. The MTS file need to be decompressed and transcoded, first...
I suggested HandBrake in an earlier reply. Did that not work?
I'm on a Mac and wondering if there is software (ideally free) that will allow me to edit and export the .MTS files?
I have a number of .MTS files that I dragged to my Mac from my AVCHD camcorder. They are just the MTS files and not the supporting folders so I can't import them on iMovie directly from the camera.
I can view the files in VLC but have to turn "deinterlacing" ON otherwise I get pixilation around movement. I tried a number of converting software but either I still get the motion pixelation or in almost all cases the quality is severally lower then the .MTS file. Is there software that will allow me to simply edit the MTS files directly or a converter that won't decrease the video quality and will allow for import into iMovie? Thanks in advance!
