I'm keen to avoid re-encoding the video, and it seems I can. Media Info shows these to be video: AVC format, variable bit rate, 16.0 max bit rate, 1920x1080 pixels, 25.000 fps, 8 bit, interlaced audio: AC3 format, 256 Kbps bit rate, 2 channels, 48.0 KHz sampling rate, 16 bits bit depth. I expect the original MTS files, with cleaned up audio, will be fine.

and, on that I suggest you may wish to visit the PP forums!Įdited to add.I forgot to mention that a little utility called Media info is very useful to analyse exactly what format your original files are: MediaInfoīob, our aim is to copy these videos onto USB sticks, for our family to watch on our various home TVs, from a media player such as WD Home TV, a media PC or a laptop via HDMI cable. However, you'll need to think about what format/codec is most suitable for what you want to do with your finished product. Depending on what you want to do with the videos once you're done, you should be able to find an export format that does little or no damage to your original quality.

However, after you've edited in Premiere Pro (even if it's just opening the video to process the audio) on export you have a wide selection of export formats. One of the things with MPEG coding is that audio doesn't exist as a discrete file as separate from video-both audio and video are coded together.
MTS is just a wrapper extension for a variety of video types.and the AVCHD you mention is (as I understand it) based on MPEG 4 coding. This is actually more of a Premiere Pro question than you know. I'll test some more and see if there are issues I haven't seen yet (I've only done one video so far). It's very quick, there's no video quality loss, the new audio is seamless and in-synch, the final file size is very similar to the original, and 'Media Info' shows the key internal video and audio specs are the same as in the original MTS video. The change in container from MTS to MKV seems OK and there's no video re-encoding. I can drag the MTS straight into Audition, fix the audio, save the audio track as a new AC3 file (in my case checking it's 48khz, stereo, 16bit, 256kbps and Dolby Digital, not Dolby Digital Plus) and then use an open source program Avidemux to open the original MTS video, leave the main screen settings as Video Output.Copy, Audio Output.Copy, Output Format.MKV Muxer (not sure about this option, there may a better choice) and in the Audio menu.Select Track, in the Track 1 dropdown.Add Audio Track, then OK, play to check it's OK, and Save as a new MKV video file. On a positive note I think there's a way that I'm still checking. It has to re-encode the video as well as combining the new audio and I can't see any way to do that without video quality loss.
To get a new MTS file with the new audio I have to save the changes, which re-encodes the video, which gives me a larger finished file with noticeably worse quality! So I'm starting to see that Premiere Pro can't do this. However it's the next step that foils me. the original video and the cleaned up audio track, which has replaced the original audio track. I have done that, by opening the MTS home video in Premiere Pro CC, selecting the clip in the Timeline, selecting 'Edit', 'Edit in Audition', 'Clip', which opens the audio track in Audition CC, where I clean it up and save, which returns me to Premiere Pro and I can play the combined result.
