Hello, I'm not certain whether this is the appropriate place to ask this question, but I hope that the video experts here may provide an answer all the same.
The situation is as follows: I'm recording HD video with a Hitachi DZHV1074 camcorder. The result is a .mov file, see http://www.linetec.nl/linux/file0034.mov (19MB) for a sample. The VLC codec analyzer tells me the following: H.264 / MPEG-4 AVC / MPEG-4 part 10 / 1920 x 1080 @ 29,97 fps sound is MPEG AAC @ 48kHz Apparently, the camera uses the NTSC format. I can use Kdenlive to render this to a DV format for further processing in Cinelerra. Loading it in Kdenlive poses no problem. The project settings I choose (format, resolution, frame rate) don't seem to make much of a difference -- but I guess that's to be expected, as the .mov itself dictates these parameters; HD 1080p 29.97 fps works fine. Then I want to render the project to DV, and that's where I hit a snag: choosing any PAL format (our native video format here) results in more or less choppy video. The effect is particularly noticeable in slow panning scenes, and once you've seen it, it keeps drawing the attention. In still scenes or fast movement, it's hardly noticeable, though. Rendering to NTSC (e.g. NTSC 1080 30p) gives perfect results, but so far, I haven't succeeded in subsequently converting this NTSC HDV material into PAL without seriously compromising the video quality or audio sync. My question: is there an easy way to create PAL HDV based on these NTSC .mov files, without visible deterioration of the quality (i.e. jerkiness, blurring or pixelization)? I don't mind if it's a CLI command, some Kdenlive setting or a Cinelerra setting -- I'm familiar with all of these. And oh, I tried all available settings in the Hitachi camera (including the 50 and 25 fps settings), but none of those produce a PAL format video file. The camera actually can produce good quality PAL output for viewing on TV, but I suspect that this is done through hardware rather than software. Anyway, my thanks in advance for any useful tips!
