How can i get a perfect .avi quality through TMPEGenc

[tony_y2k5]

i found TMPEGenc really easy , but the problem is that i cant get the quality nice! its always blobby and has these weird circly things. they say TMPEGenc has really good quality! but i cant really figure it out , o yea and i put the "DC component precision" to 10 bits and the "Motion Search precision" to Highest Quality(very slow) somebody help me please!

Use average bitrate of 8000.
Use 2pass VBR.
Use Noise reduction filter.
Wait about 40 hours to find out it's still blocky
Try Mainconcept mpeg encoder or Canopus Procoder Express.

tony,

how is the qualty of your original file? If you encode the quality WILL go down to some extent. That is the bottom line. The trick is to keep it as close to original as possible by tweaking the various settings an encoder provides. IMO you should leave the DC component setting to 8 if not encoding for DVD.
For better quality use higher bitrate as already suggested by reboot.

But hey reboot, the 40 hours wait ... is too much battering for god ol TMPGEnc Already one comparision thread is going around.

Well, given a 2-3 year old box, and motion search precision on highest, 40 hours doesn't seem that out of proportion But then, highest shouldn't be used at all, since it doesn't make any visible difference in the end product from high or even lower, while taking an enormous amount of time...

The neck of the bottle here is the Noise Reduction filter. If you thought TMPG is slowly with Highest motion search precision, thick Noise Reduction to learn what is really slowly .

[mats.hogberg]

Never use TMPGEnc filters. Filter source thru VirtualDub or AviSynth, and frameserve.

Wise words indeed!

i actually tried
"Use average bitrate of 8000.
Use 2pass VBR.
Use Noise reduction filter"

took about 4 hours Oo , avnt checked it yet though

and to answer sanjayk:
the quality is really good on the originial (the perfect quality you see now adays) i tried doing just the needed settings for a dvd *720x576 , gop structure etc* and i left the motion search to normal and the DC component to 8. and it still came out crappy.

but i should get those thingies that reboot told me to get

[reboot]

Set DC component to 10.

[tony_y2k5]

Use average bitrate of 8000.

Use Noise reduction filter.

wow i tried that combined with mine and the quality came out close to perfect! thnx

[tony_y2k5]

ermmm...i have another problem.
whenever i check it , it always says
"WARNING: NOTHING TO BFRAME DECODER LAG"
and i find it kinda annoying , does anyone know what i done wrong?
(the video works perfectly fine but it says that on the very 1st frame)

[reboot]

I get this sometimes because of the high bitrate.

[tony_y2k5]

oic . so theres no way of preventing it from happening unless you lower the bitrate?

[sanjayk]

Increase the DirectShow filter priority in TMPGEnc to max so that it reaches the top of the list. Then encode.

[Abond]

Well, this come from the way XviD decoding the first frame in some avis. Why it is so I don't know, usualy I cut the first frame with avisynth and the error is gone.

[tony_y2k5]

woah?! the files came to 3.16gb and 3.20gbs! if i put the 2 files together it wouldnt be able to fit into my discs?!

[tony_y2k5]

ermm...how do i use avisynth . i downloaded it from the site and i cant find the program to start it. i done this before ages ago but i dont remember what to do

[mats.hogberg]

woah?! the files came to 3.16gb and 3.20gbs! if i put the 2 files together it wouldnt be able to fit into my discs?!

Bitrate calculator.

You said you wanted the best quality.
If you use high bitrate, needed for premium quality, you get very large mpg's.
Buy a larger hard drive
If you want to get this onto dvd, then there are other ways to (hopefully) keep the quality up, and decrease filesize. In the end, bitrate=quality, higher is better, and you sometimes have to live with a quality loss to get the amount of video you want (in running time) onto one dvdr.

[tony_y2k5]

true , but i never knew it would become such a large file. i got it down to 2.4gb now. (i dont really mind having big files but im just worried it wont fit into my dvdrs)

[reboot]

DVDR holds 4.3 gig. Make it 4.2 to leave room for authoring.
Learn how to use the bitrate calculator
If the authored dvd is larger than the disk, use DVD Shrink to make it fit.
Not recommended, but it does work.

[tony_y2k5]

ok thanks , erm...the file is split into 2 so what should i do? should i split the average bitrate?

[RabidDog]

Dual layer discs hold 8.7gb (?) worth it if its a pristine prestige project and you want to avoid

[mats.hogberg]

ok thanks , erm...the file is split into 2 so what should i do? should i split the average bitrate?

Add the time of AV1 and AVI2 together. Get the bitrate to use from the sum. Encode each AVI to mpeg with this bitrate.

/Mats

[tony_y2k5]

hm...thats what i did and it came up to 3.16gb and 3.20

[tony_y2k5]

and i joined both of the files together and encoded it like that. but i always seem to get an error something about a line 2-3 hours through encoding

[reboot]

That's because of a fault in whatever program you used to join them.
DON'T join them. Encode separately, join during authoring.

[tony_y2k5]

kk , i just need to figure out what to change the average bitrate for both files to!!

[reboot]

What are the running times of the two videos?
Add them together. Input into the bitrate calc.

[tony_y2k5]

kk cool cool. it worked ! found out there was a custom thingy. all i need to know now it how to work avisynth!!
