Default down-converting HD 1280/720 to DVD 720/480

Hello,

I have an episode of a TV series recorded in MPEG2, 1280 x 720 , NTSC, 59.940 fps, DD5.1, 16x9 AR, 24Mbps bitrate. The file size is good and it fits a single DVD-R ... however I'd like to make it playable on my standalone DVD player, but TMPGEnc DVD author freaks out on me because of the higher-than-normal specs

btw. I wanna keep the 6 channels audio and 16x9 aspect ratio

what should I do , how can I do it ?

thanks
R

One set of procedures (other posters may/probably will suggest alternative methods) would be:

1) If not already DVD-compliant, use "TMPGEncPlus" to convert the MPEG to compliant MPEG2-for-DVD format - Use "TMPGEncPlus's" DVD wizard/template to accomplish this (This step may not be necessary, if your MPEG-2 filies are already in DVD compliant format)

2) Use "TMPGEnc DVD Author" (a different program than "TMPGEnc") to easily create the required additional DVD files and structure (and chapters and a menu, if you wish)


**If the combined filesize of the DVD "package" written to your hard drive is greater than 4.37Gb, use DVD Shrink (or similar) to compress


If your O/S is either Win2000 or WinXP, TMPGEnc DVD Author can also burn your DVD. Otherwise, use NERO to burn in "DVD-Video" mode
(As an alternative to "TMPGEnc DVD Author", you could use "DVDLab")


Let us know of your success ;>}

thanks setarip for taking the time to reply.

I tried the latest TMPGEncPlus but it's a no go in Step 1. This is because it does not recognize AC3 (DD5.1) as a valid audio source in the original multiplexed mpeg

in the mean time I had some success using DVD-Lab to demultiplex the AC3 track from the mpeg file, then using its "audio delay" feature to insert -500ms audio delay (to get it in synch with video)
then I fed the original mpeg file to Sony DVD Architect and had it re-encoded to DVD complaint stream.
I had to have the AC3 file in the same directory as the original mpeg, only then Sony DVD Architect would have an audio in the multiplexed mpeg (strange I know)

"I tried the latest TMPGEncPlus but it's a no go in Step 1. This is because it does not recognize AC3 (DD5.1) as a valid audio source in the original multiplexed mpeg"


In TMPGEnc, under the "Environmental Settings" "VFAPI plugin" tab rightclick on the "Direct Show Multimedia Reader" and increase to one greater than the highest priority of listed items. This will enable TMPGEnc to accept a properly encoded .AVI with .AC3 audio for input...

thanks! but this is of no help to me.

my original files are MPEG2 format, not AVI.

my solution with DVD-Lab and Sony DVD architect is working for me at the moment. It takes about 3 hours of computer time for two hours of HD video with 5.1 DD audio to process.

"thanks! but this is of no help to me.

I'm sorry but ".AVI" was merely a typo on my part. If you change the "Direct Show Multimedia Reader" setting as I directed, you'll find that "TMPGEnc" will accept the .AC3 audiostream that is part of your MPEG-2 file...

I did what you suggested, but it still woulnd't recognize the AC3 stream in my MPEG2. I also demultiplexed the Ac3 audio to a separate file .ac3, but it wouldn't open that either

Anyway at the end it doesn't matter, because it wouldn't encode the audio in AC3 (5.1) anyway and this is what I want

Sony DVD architect does this for me fine
