Thank you Einar. Two questions on that: 1. suitable bitrate DNXHD seems to me the most feasible format. Almost anywhere they recommend as video bitrate 185 Mbps. However on this page¹ it says that this is the bitrate for 1080i/50 which results in 25 fps. My camera gives 50 fps (1080p/50) which would require a higher bitrate which is however not mentioned in the table. In some forum someone recommends 240 Mbps for 1080p/50 projects. I tried both bitrates and surprisingly if I choose 240M the resulting files get smaller than the 180M ones. So which bit rate do I use? 2. suitable audio codec. The page Einar mentioned recommends pcm_s16le as audio codec. However my installation of cinelerra does not like it for some reason. It says new_acodec: couldn't find codec for "lpcm" and the playback is again unstopable. If I put an imported .wav into the timeline, everything's fine.
