Same question: What render combination are you tried?
I use carefully the same as input because if not I will lose synchronization and quality. I use MJPEG for video at least 50% quality in avi container. And WAV PCM 16 bit 44100Hz stereo for sound. I just export the video and audio separately because I give best results, specially in A/V synchronization.

I understand that cinelerra can't work with those natively, so I followed some instructions I found to convert them: http://www.fsckin.com/2008/01/03/transcoding-mtsm2ts-avchd-video-files-with-free-software [1] In my setup, I have played with the final ffmpeg step and settled on: ffmpeg -r 29.97 -s 1920x1080 -deinterlace -i $videofifo -i audio.ac3 -vcodec mpeg2video -sameq -acodec copy -aspect 16:9 outputfile.mpg The resulting mpeg file has fantastic quality and cinelerra will import it to edit without complaint. My problems begin when I render the output. I end up with pixelation, artifacts and generally youtube quality output. Not what I put into cinelerra. I have tried multiple render combinations and the all seem to loose significant quality. My question has a few parts. A) I'm sure I'm doing something wrong, can you point out what it is? B) Is there another way to import the avchd into cinelerra? C) Am I just S.O.L. with avchd for now and have to keep a windows machine around to edit it? (please say no). If anyone needs, I have small sample files from all stages of this operation I can supply. thanks in advance for any help. Andy.
