Several people at the LIghtworks forum have tried using FFMPEG commands to convert mts files to mp4 or mov (see link in earlier post for an example) and they always get this same error: Application provided invalid, non monotonically increasing dts
I navigated to the directory where the files were and this is the result (see below). I tried using the Windows command prompt to run the FFMPEG string to see if it shed any light on why it was not working. Here are MediaInfo results for the two AVCHD files.Ĭomplete name : C:\Users\username\Desktop\avchd_conversion_batchfi les\tom.mtsĬhannel positions : Front: L C R, Side: L R, LFEĬomplete name : C:\Users\username\Desktop\Lightworks\Video samples\Stefan MTS\00076.MTS However, when I imported it into Lightworks, the video was black. I tried changing mkv to avi in the MPEG I-frame bat file and it did indeed create an avi file. I found this thread on converting from MTS to MPEG I-frame but in an m2v container. I have been searching the forum for a way of doing the latter and I found various threads dealing with conversion from MTS to other formats. So what some people have been doing is re-wrapping MTS to mp4 and then transcoding to MPEG I-frame on import into Lightworksī) transcode from mts to MPEG I-frame HD in an AVI container. Lightworks uses the Matrox VfW codecs and can transcode to MPEG I-frame HD on import. Intra-frame codecs like MPEG I-frame HD are much easier to work with. I found a way of re-wrapping MTS to mp4 using Mediacoder but it doesn't work consistently so I am looking for a more reliable method.īut even if users do succeed in re-wrapping their files, they don't always play back smoothly in Lightworks except on the most powerful PCs (although long GOP performance is on the developers' roadmap).
Lightworks can currently handle AVCHD in QuickTime containers but not MTS. I have been beta testing the new and soon to be open source Lightworks NLE and trying to find a way of helping people to convert from AVCHD MTS to a format that it can handle.
