Too much time to reencode ...

[mc4]

Hi, when I backup my DVD movies, I usually use TMPGEnc Plus 2.5 to reencode my MPG2 files. Right now I'm reencoding "Blade" and I got almost 45 hours to pass from 4.900 kbps to 4.750kbps, so I can have a m2v file with almost 4.0 GB to fit a DVD 5.

Is this 45 hour period common or what. With other movies I never need more than 10 or 12 hours to reencode all the mpg2 file.

BTW, I tried with ReMPG2 and did reencode it in 6 hours, but the quality wasn't as good as I want. Is there any other reencoder that I can try with more quality and not so slow (45 H)?

Thanks,

Mike :confused:

Without telling us your computer specifications (CPU speed, memory, etc) we can't tell you much. I can tell you that on a Pentium 200mhz, 45 hours is excellent, while on a P4 2.4ghz, you should be seeing better performance.

General performance optimizations... play with your TMPGEnc global settings and increase the memory buffer if you have plenty of RAM on the computer. Don't use filters, as they are particularly slow in TMPGEnc. If you must use a filter of some sort, learn AVISynth and use that for your filtering. Heck, AVISynth may speed things up if you're encoding from mpeg2 to mpeg2, I'm not sure what the current guide suggests doing.

Encoding at high bitrates in TMPGEnc is time-consuming. If it really becomes an issue, try using CCE. If the DVD you are backing up is just a little bit too large to fit on a DVD-R, try DVDShrink, as well, which is a one step process. The quality is, imo, better than ReMpeg at most settings. For smaller DVDs, this is probably a more ideal solution than a full reencoding.

Without any filtering, my P4 1.9 does the encoding with factor 1:1.5 - to 1:6 (single pass). Speed depends on the Video (interlaced or progressive, high action etc.)
Never use the setting Highest Quality in TMPGEnc, because it is realy slow and it gives you NOT the bestest quality in some cases.

mc4 ,
you can try to use CCE to do the reencode. Conheces o site Português (http://www.dvdtodvdr.cjb.net) sobre dvds?

Erik,
Sorry, I forgot to tell that I use WinXP Pro in a P4 - 2.4GHz and 512MB of ram. I have also plenty of HDD, 80 GB + 120 GB, so I don't understand why I got so much time to reencode.

Also I didn't use the "Highest Quality", but only "High Quality", I also use 2 passes VBR. One thing that I don't understand also is that when I reencode this particular mpeg2 file, I didn't see the image of the movie in the black square that I usually got in other movies, so I think that it isn't reencoding at all, although it states that it last 45h... to finish reencoding.

BTW, how do I increase the memory buffer ?

Yes, I'm reencoding from mpeg2 to mpeg2, so how can I use AVISynth ?

The original bitrate of "Blade" is Avg=4.900.000bps, Max=8.000.000 bps and Peak=9.150.000 bps and I'm reencoding it to 4.750.000 bps, so I can have a m2v file with 4.000.000 Bytes instead of 4.350.000 Bytes, so it fits (with the audio and subtitles) in a DVD5.

Any idea about wht's happening ?

Thanks :confused:

High quality doubles your render time...and VBR 2-pass doubles that. Deselect high quality...and instead of VBR 2-pass use CQ (Constant Quality).

For that what you're doing, you should use DVDShrink anyway.
