I usually encode MPEG-2 video in PAL DVD format, with the Constant Quality method, quality set at 100 (maximum), and the min/max bitrate left at 2000/8000 as it comes. I also use the slowest motion search, and 10 bits of precision (I want quality above everything else).

So, I generally get good quality, but at some points the enconded video shows some artifacts on screen (little but noticeable squares). They don't appear too often but they appear nonetheless, and I would like to make a completely clean video in order to archive it into a DVD. In addition, if I encode the same video twice with the same conditions, the artifacts can perfectly appear one time but not the other.

I don't know if it matters, but I use AviSynth in order to frameserve the video to TMPGEnc from an Adobe Premiere project.

Thanks for your help.

If you can try loading the file directly into tmpgenc and encodeing it without useing AVISynth or Premier and see it the problem get"s better...?

You may want to try using CBR (Constant BitRate) instead of Constant Quality. The file size will increase compared to the Constant Quality mode, but you will always have the same bitrate (8000kbps or whatever you set as the bitrate). This MAY eliminate the blocks you are seeing.

If you are making a reference archive of "difficult" original material, 8Mbs may not be enough. Also, if the source is Hi8, or similar, consider using 4:2:2P@ML.

Run the BitrateViewer tool to see what your Q levels are in good versus bad areas of the footage. Adjust max Mbs to keep Q low and use 2pass if you need to conserve file size.

DVD compliant video might require more experimentation, but you should be able get a virtually lossless result even at 8Mbs.

I don't think 4:2:2P@ML is a valid level for DVD authoring.

I encoded an mpeg file with the 2 pass variable bit rate with 2000000/4000000/8000000 min/avg/max settings respectively. The resulting output file is almost exactly the same size as one encoded at a CBR of 8000000. I tried the same encoding with the Dazzle MovieStar software, and the variable bitrate encode came out to roughly half the size of the CBR 8000000 encode.

I would have expected the TMPGenc VBR output to be noticably smaller than the CBR setting. Is there a reason why?

Thanks.

This shouldn"t happen so I wouldn"t know why...

Hi folks

I can`t finish the decoding job (AVI 2 MPEG) cause the program is always hanging after a while. Sometimes it stopps after 14%, sometimes after 45%.. After hanging the whole computer has stopped...can`t move the mouse.... even the numlock-light has no reaction.... tried to change the codecs, but no reaction..please help me !!!!!!!!!

Is this with every file or just with just a certain file...?

No, it is always the same.... got the same thing when I use the Windows Media Player 8....after a while playing the movie stops and the whole computer is frozen....seems to be a software problem...but I dont know....want to reinstall WMP 8 but can`t find it anywhere (execpt on the Win XP CD) but I can not uninstall the player cuz it does not appear under "Add/Remove Software" in the control panel....So seems to be the same prob by WMP and TMPGENC...Any suggestions ?

You can un-install media player in XP By going to "Controll Panel" to "Add/Remove Programs" to "Add/Remove Windows conponents" ,it"s on the side of the window....Well if you are haveing this freezeing problem when doing other things besides encodeing then it could be a Conflict in your system or something....?

THX for answering my query....just encoded another AVI-File and it worked this time... I am now trying a third one to know whether it depends on the one file or not...perhaps the one file has a broken frame or something like that.. i can watch it normally (without any errors) on PC but can not encode it.... so I will try another one to know... Is it possible to re-code it from AVI (with error) to AVI (without errors) ??....Can`t still find the WMP8 uninstall option under "Add/Remove Windows Components".. :-??

By the way: What is better: CBR or VBR ? Is a CBR of 1800 enough for viewing a SVCD on DVD Playa ?

THX in advance

PP

No...no luck again...freezing again and even with other AVI-Filez... :-((

It You are haveing this problem Quite often andf even when not encodeing, maybe you should consider a Clean Re-install on your OS and start from Scratch..I actually do this about 0nce a Month because of one problem or another and it is easier than hopeing the problem will fix it"s self and quicker that Trying to figure out what the problem is for a long time and still not fiXing it...Just a Thought...

I have an half-our AVI file I made from a video. The AVI file is fine. But after I encode it to MPEG1 using TMPGEnc, the sound gets farther behind as the mpEG is played. At about 20 minutes in the sound is about 7 secinds behind the video.

Any suggestions?

Thanks!
Jim

You say this AVI was made from a Video...Do you mean that it was Captured from a Capture card of some sort from TV or VCR??This can be caused by Dropped frames while captureing, depending on what capture program was used some don"t compensate for Dropped frames..Or if you didn"t drop frames you can still have sync problems cuz when captureing the Soun card usus it"s own clock to mesure time and so does the Capture card, and in most cases there is a Little differance between the to clocks so ove a Long capture the sound will go out...most of the good capture programs compensate for this by adjusting the Audio frequency...

Your CPU/motherboard combination may not be quick enough. I had the same problem with a Pentium III.

I got round it by setting the "Output bitstream for edit (Closed GOP)" flag on the GOP structure tab in settings. After that, synchronisation was perfect.

i downloaded 5.8 and opened it but it does not seem to load on to computer i put in the licn.# and hit ok it just opened up i went to programs to see if it was there and it wasn't. i went to add/delete programs and it was't there so i loaded a avi to encode and the preview window is black. what am idoing wrong and could some one walk me threw set up

i have 3 avi files that i want to put on cd so it will play on DVD players (it dose play VCD's) could some one tell me how i would do this, i have Easy CD Creator 4

Hi,

I am trying to convert a series of jpg images into a mov filr for an animation.

I keep on getting an error (can't load "P3Pakage.dll"). The jpg image file is 768 x 576 and there are 400 of them.

Any idea on what is going wrong. WHat image size do you recommend.

Please email me at spalding@rivernet.com.au if anyone can help.

Thanks in advance

Brad

Delete and re-install TMPG and check you have the file in you TMPG folder.

ASHY

And I don"t think you can use Tmpgenc to convert files to Mov format...

Hi
I am using your program to convert avis to mpeg1 and everything works very well,I just have one problem. When the resulting mpeg is burned into a vcd,If there is a long pan shot then the video seams to give little skips about every 5 secs. This isnt a big problem but I would like to know if ther is a way to fix it.
SYSTEM: pIII 600 512mb ram winxp pro
Thanx for any help u can give

Rix500,

This could be to do with your settings in TMPGEnc.
Can you check what frame rate the original AVI is and then let us know what settings you used to encode?

I am using the pal vcd template, full screen (keep aspect ratio)in clip frame,and normal on the motion precision, thats about it as I dont realy know what all the other settings do.
Most of the avi files seem to be 23 fps
Thanx again for the help

I'm no real expert so maybe someone else can offer more help, but ...
I would first off suggest you raise the motion search precision to high quality rather than normal.
And secondly (and perhaps more importantly) go through the project wizard and make sure that if your AVI is 23.976fps that you chose the NTSC film template. (Use VirtualDub 'file info' to find out the FPS).

This will output your film at the same FPS as it went in.

Most DVD players will be happy to play VCD's in a variety of formats. You don't need to output in PAL format.

Try it on a short piece of of AVI to see if it helps rather than encoding a full 90mins.

The problem is because you are changing the framerate of the original AVI. TMPG can NOT do this correctly.
Most DVD players will convert a 23.976 fps movie to 25 fps, but I'm afraid the result will be just the same as you are experiencing now. Jerky playback as most don't do real framerate conversion.

You need to convert the AVI's to the correct framerate prior to encoding or use AVIsynth to do the correct framerate conversion.

I have extracted the .DAT mpg1 files from 24 video cds and I want to compress them smaller for playback on an IPAQ. The first 8 worked perfectly, however when I try to open 9 thru 24 I get the error "can not open or unsupported". I tried changing the VFAPI plug-in priorities, as I saw in other posts, but it has no effect. Any ideas?

Thanks

Try de-muxing the File and just encodeing the Video ...if it loads just mux the audio to the encoded video...Re-encodeing the audio will cause problems sometimes anyway....

Why and what did you use to extract the MPEG. VCDgear by any chance?
TMPG is capable of opening the .dat files directly without extracting first.

If you wish to extract the MPEG from the .dat file itself. Just load the .dat file into both fields in the the simple multiplexer and click run.

Everytime I try to encode an AVI to mpeg I get horrible purple bleeding that happens on every video I've tried. I wonder if anyone has heard of this before and knows what to do to resolve it?

It sounds like a "Angel Potion Codec" Problem...If you have the Angel potion Codec installed get rid of it ...It causes this discoloration ...but if you don"t have that codec then try raiseing the "direct Show" file reader in the "Vfapi Plugins"...

yup that was it, thanks a million

hey I need to know where do I find if I got Angel Potion codec install on my computer because I get purple when I try to convert a movie it fades in and out during the movie please help? but I have been read the message board and I think this is it. thanks

I'm using windows xp along with a pentium 4 2.0 ghz with enough memory and shit, but when i try 2 use "merge and cut" for splitting a svcd (made by tmpgenc) in 3 parts TMPGenc shuts down and i get the well-known message that an error has occured and microsoft wants 2 know about it.

Am i doing something wrong, is windows xp fucking it up or should i buy a new machine?

NO..What you need is a different Mpeg editor...Tmpgenc"s mpeg editor isn"t very good...Well it is good when it works But that isn"t as often as It should....

Try completely deleting TMPG first then re-install it.
If that doesn't work try an earlier version such as v2.56 and below.

I remember reading somewhere that VBR two pass does not work with Ulead Media Studio yet.

Is it working now?

If not, does the Pro version of TMPGEnc works?

Cheers

Why would we Know ????The Mpeg encoder in Media studio isn"t very good ...you can do 2 pass with any version of Tmpgenc...

how do i install this? it doesnt say how in the website? im going to use it with premiere.

You can"t use it with premier....The only way to use it with premier is to use the "Premier Video server" from "http://www.videotools.net/...and frame serve it to tmpgenc or any other encoder...and it is Very slow...You are better off getting a real Mpeg plugin for premier...
