cam compatible HDV edit chain, part II (short)

I posted a more detailed version of this two posts ago (http://crazedmuleproductions.blogspot.com/2006_10_01_archive.html), but I thought I'd reiterate it in a shorter format:
1) from Cinelerra, export video using YUV4MPEG using mpeg2enc (.m2v) compression scheme with special params:
mpeg2enc --verbose 0 --aspect 3 --format 3 --frame-rate 4 --video-bitrate 18300 --nonvideo-bitrate 384 --interlace-mode 0 --force-b-b-p --video-buffer 448 --video-norm n --keep-hf --no-constraints --sequence-header-every-gop --min-gop-size 6 --max-gop-size 6 -o %
2) from Cinelerra, export audio using mpeg audio, layer II (384Kbps)
3) multiplex audio and video streams to MPEGPS (Program Stream) format using mplex:
mplex -f 3 -b 2000 video.m2v audio.m2a -o output.ps
4) convert .ps to .ts, MPEGTS (Transport Stream) format using VLC
5) export to cam, consider using 10sec blank leader

Update 5/17/2009
Note that if you bring the video into Cinelerra and the thumbnail is green, this means that the first frame of the video is not a keyframe. This is a problem with VLC. You can avoid this problem by using this ffmpeg command in place of Step 4 above:
ffmpeg -y -i OUTPUT.ps -acodec copy -f mpegts -qscale 1 OUTPUT.m2t

Once the video is converted, you may then output to the camera using test-mpeg2 from libiec61883:
/2006/10/success-and-failure-in-land-of-dvhdv.html

Also, take note of a possible 2GB limit in libiec61883 uploading your content to the cam:
/2006/10/libiec61883-now-exports-files-greater.html
*** end update ***

Update 11/17/06
Last night, I found that doing performing other operations on your system like surfing the web or playing audio while running mplex or VLC convert may cause problems with the video as it uploads to the camera. So don't do anything while you convert your videos.

In my case, I was 28 minutes into an hour long video uploading to the cam when the import stopped. I no longer had uploading video displayed on the LCD screen of the cam. I only saw blue, the upload seemed to continue, but I got no final output. The solution was to remux the original streams using mplex and rebuild the MPEGTS using VLC. The important point being that one of these two processes is very sensitive to fluctuations in CPU or hard drive performance. So leave your PC alone while these processes are active.

That's all she wrote for today. Enjoy!
