I have captured some video from my old hi-8 Sony using my LML33. Parts of the video obviously have swapped interlace frames but most of it is corret. Is there a filter or other method in Cinelerra to swap the frames back?
I think the right combination of the effects "frames to fields" and "fields to frames" will do the trick. 1) Set the project framerate to 50 frames per second (or 60 in NTSC land), 2) load the DV file 3) apply the "frames to fields" effect, set the field order that makes the playback progress steadily, and not back-and-forth (Top field first or Bottom field first) 4) Render this to an uncompressed, lossless format, if you can. 5) Load the newly rendered, line-doubled progressive video into Cinelerra, and apply fields to frames, with the appropriate field order for DV. 6) Now you still have one problem left: The project is still at 50 frames per second, and you need to discard every second frame to get valid DV output. The tedium! 7) Consider using ffmpeg for this instead. You can specify field order on the command line, according to ffmpeg's man page. -- Herman Robak _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
