Long encoding times in TMPEGnc Plus

[Ängsvik]

I run TMPEGnc Plus 2.5 on a P4 2,0 Ghz 512 Mb Ram PC running XP Sp1. Lately I have been plagued by very long encoding times, last night I encoded a SVCD that is 43 min long and it took over 10 hours! I use 2 pass VBR and the Highest Motion Detection setting which admittedly says it will be very slow but earlier I have done similar encodings in about 5 to 6 hours. Does the fps setting affect the encoding time? Because this movie was quite short and I set the fps to make the finished file be 99% of a 80 min CDR the fps was above 2400. My earlier encodings have had fps of about 1700. Thanks in advance-Lars

I don't believe bitrate affects the encoding time. I believe that's what you are referring to when mentioning "fps?" If you want to speed up the encoding time, set your motion precision estimate to "fast." I use this setting when encoding mpeg2 files. So, a ninety minute movie (@720 x 480) would roughly take around five and a half hours or so to encode.

Honestly, I have used the highest quality (very slow) setting and there is no noticeable difference in the end result to me. Another factor that lengthens encoding time is the use of filters. The more you utilize, the longer the encoding time becomes.

Hope this helps you out!

ive had tmpgenc do this to me in the past when using it with dvd2svcd, 1 day it just decided it was from then on it was gonna take 3-4 hrs longer than normal, i didnt change anything for this to happen? i has to re-install xp on a seperate issue but upon reinstall tmpgenc was back to normal? go figure i never got to the bottom of it so id also like to know whats happening? but im not 4 1 minute suggesting u go to the trouble of reintalling win xp,

Have you always used 2 pass VBR?

[Ängsvik]

Hello again, yes I have always used 2 pass VBR. I have used the two highest motion detection settings intermittenly with no real noticeable difference but I read in some forum that you should always have the highest setting. Being obedient I followed that advice :P I woul also rather not reinstall XP since my computer came with it preinstalled so I do not have the xp cd's only some kind of disc mirrors that erases all of my stored data.[/quote]

'Highest Search Precision' only guarantees very very long encodes. There is absolutely no noticable improvement in quality with the highest setting. None.

Try with 'Normal' and then do the next higher level. I think you'll find Above Normal/High is more than adequate. And make your encodes 2 hours instead of 10.

Or use MainCocept 1.4!!

Dear All, Thanks for your help! I moved the motion search down to just that motion search (fast) and set the priorities to High in TMPEGnc and tried again, this time it took 2hrs 14min as compared to 9hrs 34min with no noticeable difference in quality. WOW!!! I have spent alot of time waiting for TMPEGnc unnecessary!! Thanks anyway for your help-Lars

I use Motion Estimate (fast) and I think the results are great.
