I installed FFMPEG by following the guide on page one of this forum.
I then installed WINFF through the terminal.
I would prefer using OpenShot to edit. It works with MTS, but MTS lags. It is not smooth during preview (same in Windows).
Do you suggest I delete ffmpeg (that I got from this forum guide) and use only WinFF?
Edit: I am using ffmpeg via WinFF, in the case I was not clear. The posts prior to the last 2, i was using only ffmpeg and not WinFF.

OpenShot is laggy with the MTS files for me too, unsurprisingly, but you can re-encode the MTS files to a lossless intermediate file that will run much more smoothly in OpenShot:
I hope you have adequate disk space because this will create some huge files. If this is unacceptable then I can give another example that will use a lossy encoder but should, I'm guessing, still play somewhat smoothly in OpenShot.Code:ffmpeg -i input.mts -c:v ffvhuff -c:a copy output.mkv
You can make a custom WinFF preset based on my example and then you'll be able to use your compiled FFmpeg and WinFF. WinFF itself can use any FFmpeg version, but its default presets won't work with all versions of FFmpeg.

shall get back to you after using this command. trust you will be around later.
Edit: I understand that ffmpeg would give me flexibility over presets that WINFF won't. I would prefer FFMPEG. But the need to get going makes me opt for WinFF. I hope to get the commands for FFMPEG and understand them

Code:ffmpeg -i input.mts -c:v mpeg2video -qscale 2 -c:a copy output.mkv
- -c:v mpeg2video: codec, video using encoder named mpeg2video
- -qscale: quality level for video output. A value of 2 for MPEG-1/2/4, in my opinion, can usually be considered "roughly visually lossless".
- -c:a copy: copy the audio from input to output. Does not encode, but it is more like a "copy and paste".
I just realized my MTS samples are all stereo (2 channels), so I'm unsure if my example commands will work with 6 channel or if OpenShot can handle 6 channel inputs.
I tried your codes. Got the following error:
[*** @ 0x9731320] Only SUBTITLE_*** type supported.
I know nothing of subtitles, but you can add -sn to the command (before output.mkv) to disable subtitles. That should work, but I don't know if you want to keep the subtitle stream.
Importantly, you had mentioned that there are various websites with outdated information. Would you recommend any one website (I will search the forums of course)? Where I can read and try to interpret? For example, changing output folder once and for all.
As per your estimation, this website is outdated...
Would this be the best and the simplest one?ffmpeg -i input.avi -sameq output.mpg

example) or I think you can create a custom preset in WinFF and then use that to select and encode all of the files.
ffmpeg-user mailing list are all good resources.
