Inverse telecine... I'm editing my HV20 movies using almost the same process you described above. The first thing I do is to process the .m2t file with projectx. This removes the B-frames at the beginning of the movie and synchronizes the audio with the resulting video. I found out that if I don't do this, the B-frames get removed by the Avidemux anyway, but the audio is not synchronized with the video ( there is a delay, smaller on some movies, bigger on others, depending on how many B-frames there are in the beginning until the first I-frame). Projectx outputs two files, a .m2v (the video) and a .mp2 (the audio). Next I open the .m2v and .mp2 files file with avidemux, apply Decomb telecide with stock presets, Decomb decimate with Pulldown dupe removal mode (I think it also works with with stock presets), a crop filter from 1440x1088 -> 1440x1080 and a Mplayer resize filter from 1440x1080 to 1280x720. I export the result as an AVI with MJPEG codec for video and WAV PCM for audio. This AVI file can be opened with cinelerra without any problem. Make sure you set the correct format in cinelerra (Settings -> Format), especially the Frame rate to 23.976. If the frame rate is set to 29.97 cinelerra will reinsert dupe frames to correct the frame rate. Cinelerra used to freeze in my case also until I enabled the "Stop playback locks up" option in Preferences, Playback window. Now it works perfectly. Blueray AVCHD Multiplex into .avi format with AVC and AC3 audio using avidemux_gtk Remultiplex into .vob using ffmpeg in copy mode Remultiplex into blueray using tsremux Blueray Lossless HDV Multiplex into MPEG-PS using COPY video and AC3 audio with avidemux_gtk Remultiplex into blueray using tsremux For HD-DVD Multiplex into MPEG-PS using COPY video and COPY audio avidemux_gtk Feed output file to dvdauthor LaserFan, that's perfect! Thanks for pointing these options out! These options are available in the Windows binary included with MeGui but are not present in the current development code on Git. The development code for x264 must be patched for --tff and -bff as well as --nal-hrd. The patches are at files.x264.nl/x264_patches I now have a functioning workflow: Video: HDV -> dvgrab -> cinelerra -> x264 -> copy to windows -> h264info -> tsmuxer -> MF6+HD -> HD-DVD 4.7GB Audio: cinelerra -> wav -> ffmpeg -> ac3 -> copy to windows -> tsmuxer wav -> AC3 conversion ffmpeg -i p.wav -ab 128000 p.ac3 The resulting disk contains MPEG4AVC at 1440x1080i and plays in my Toshiba HD-A2. x264 configurations from MeGUI Standalone-HD-DVD_Fast program --pass 2 --bitrate 8000 --stats ".stats" --level 4.1 --keyint 14 --min-keyint 2 --ref 2 --mixed-refs --bframes 2 --weightb --direct auto --deblock -1:-1 --subme 5 --partitions p8x8,b8x8,i4x4,i8x8 --8x8dct --ipratio 1.1 --pbratio 1.1 --vbv-bufsize 14475 --vbv-maxrate 24000 --qcomp 0.5 --merange 12 --threads auto --thread-input --progress --no-psnr --no-ssim --output "output" "input" --mvrange 511 --aud --nal-hrd Standalone-HD-DVD program --pass 2 --bitrate 8000 --stats ".stats" --level 4.1 --keyint 14 --min-keyint 2 --ref 3 --mixed-refs --bframes 2 --b-adapt 2 --weightb --direct auto --deblock -1:-1 --subme 7 --trellis 2 --partitions p8x8,b8x8,i4x4,i8x8 --8x8dct --ipratio 1.1 --pbratio 1.1 --vbv-bufsize 14475 --vbv-maxrate 24000 --qcomp 0.5 --me umh --threads auto --thread-input --progress --no-psnr --no-ssim --output "output" "input" --mvrange 511 --aud --nal-hrd YUV4MPEG2 W1440 H1080 F30000:1001 It A15:11 C420jpeg FRAME YUV4MPEG2 W1440 H1080 F30000:1001 It A15:11 C420jpeg Standalone-Blu-ray_Fast program --pass 2 --bitrate 8000 --stats ".stats" --level 4.1 --keyint 24 --min-keyint 2 --ref 3 --mixed-refs --bframes 3 --weightb --direct auto --deblock -1:-1 --subme 5 --partitions p8x8,b8x8,i4x4,i8x8 --8x8dct --ipratio 1.1 --pbratio 1.1 --vbv-bufsize 30000 --vbv-maxrate 40000 --qcomp 0.5 --merange 12 --threads auto --thread-input --progress --no-psnr --no-ssim --output "output" "input" --mvrange 511 --nal-hrd --sar 1:1 Standalone-Blu-ray program --pass 2 --bitrate 8000 --stats ".stats" --level 4.1 --keyint 24 --min-keyint 2 --ref 3 --mixed-refs --bframes 3 --b-adapt 2 --weightb --direct auto --deblock -1:-1 --subme 7 --trellis 2 --partitions p8x8,b8x8,i4x4,i8x8 --8x8dct --ipratio 1.1 --pbratio 1.1 --vbv-bufsize 30000 --vbv-maxrate 40000 --qcomp 0.5 --me umh --threads auto --thread-input --progress --no-psnr --no-ssim --output "output" "input" --mvrange 511 --nal-hrd --sar 1:1
