Faster way to encode 1280x720 @ 59.94 fps to 720x480 @ 29.97

[sohr]

Hi everyone...

I've read all the FAQs and searched through all the guides, and I hope this is the right forum for this question.

I have a few TV shows (originally broadcast in 720p_ that I'm trying to archive onto DVD.

The files I have are MPEG2 files, at 1280x720 @ 59.94 fps.

It seems Nero and several other programs have serious problems with these files due to the non-standard FPS.

I'm currently using TMPGEnc Express to encode them to the standard DVD resolution (720x480 @ 29.97fps), but so far it looks like its going to take about 16 hours to encode 2 hours of video. This is on a AMD Athlon 64 2800+ with 512MB of RAM. This is with no filters at all, dual pass, and VBR.

Does this seem kind of long? Isn't there some tool that can simply cut half of the frames in my source material while keeping the audio in sync so that I have a proper 29.97 fps source that I can use in Nero without having to reencode?

Also, on a somewhat related note, I've seen where its stated the standard resolution of DVD is 720x480... yet some software tools offer to write DVDs at 704x576. Are DVDs at the higher resolution not as compatible as 720x480 DVDS? Or is there some other reason why every DVD isn't burned at the higher resolution?

Thanks!

Way too long. Try Tmpgenc plus instead.

You must reencode, the fps and the video size is not dvd standard.

For NTSC, 720 x 480 OR 704 x 480. 29.97fps
For PAL, 720 x 576 OR 704 x 576. 25fps

Thanks, Baldrick. Is Tmpenc Xpress known for being that much slower? And ballpark, how long should it take to encode two hours worth of 720p MPEG capture?

Tmpgenc xpress is not slower than tmpgenc plus but you could still try and see if it is slow with both.

Try also other mpeg2 encoders like mainconcept mpeg encoder, canopus procoder, cce (trials available)...all faster than tmpgenc.

You can also try frameserve the mpeg2 from dgindex or avisynth to tmpgenc. maybe the mpeg2 decoder in tmpgenc xpress is not that gooooood.

I've had good luck with VSO DivxToDvd . Give it a try. It is fast.

FYI: 704x480 @ 29.97fps is the common SDTV digital broadcast standard in the USA and directly supported by DVD.

a. Look in the guides here https://www.videohelp.com/guides.php?guideid=744#744 for tips on Xpress

As someone using both I find that XPress is slower, however that is because the defaults are for better quality in Xpress. SO I use TMPGenc Plus for speed and Xpress where Quality is needed. And of course Xpress takes the input file(s) and sets the bitrate so they'll fit onot a DVD for you. I Run Plus when I need quick and Xpress when overnight is OK. Xpress is running now on my home computer. A Complete encode to 720 by 480 usually takes 12 to 14 hours. 352 by 480 is quicker.

The Main difference that also influences my decision which to use is the AC3 plu-in for Xpress. If I have a AC3 sound source such as a PAL DVD then I always use Xpress rather than have to fiddle around extracting AC3 sound etc. I don't do many of these PAL DVDs (I'm on a budget) so Quality output means more to me than time.

Since you didn't mention what type of sound....
I'm guessing Nero and others have problems with these files due to AC3 sound.

Another thing to save time encoding is do any editing before encoding. I use Videoredo as it handles .TS streams and AC3 sound.

Cheers

Edit: I've never had sync problems with plus or Xpress. Also the same AC3 plug-in works in both Xpress and DVD author. They just work, not the cheapest or free but solid. Same reasomn I use ASUS Motherboards. Solid not cheapest.
