2-Pass VBR Problem Not Only With MPEG4

[aamir12345678]

I used to encode VCD's, SVCD's, etc with TMPGEnc Plus using 2-Pass VBR, and I would always get the results I wanted. However, about 2 or 3 weeks ago, the 2-pass VBR stopped working right. I either get an "Illegal Floating Decimal Point Calculation Order" error or the encoder produces a video that has a significantly lower average bitrate than the one that I asked for. It seems to be pretty random as to which problem I get.

I've tried frameserving, increasing the DirectShow priority, uninstalling & then reinstalling TMPGEnc, formatting Partition C: of my hard drive (leaving Partition E: with all of the GB's of videos & other files), reverting back to Windows 98 SE from XP (while Partition E: still has all of the files), etc.

Some people told me it was the particular source files I was trying to encode, while others told me it had to do with TMPGEnc's problem with encoding Divx or Xvid in general. I've checked the files for errors with VirtualDub, and it found none; so, I've tried two things. I ripped one of my Dvd's, encoded to Divx, then encoded to Mpeg2 using TMPGEnc Plus's 2-Pass VBR. I still got an average bitrate lower than what I asked for. I also took one of my very old VCD's. I did this VCD quite a while back. I tried to encode that using 2-Pass VBR in TMPGEnc Plus but got the same problem. Seems the problem isn't just Divx or Xvid.

CBR, CQ, etc work correctly most of the time, but once in a while, they have problems too. I've used other encoders like Mainconcept. It does it without any errors, but #1 : Mainconcept doesn't produce the same quality that TMPGEnc does & #2 : I've already paid for TMPGEnc Plus; I am not spending another $150 to get Mainconcept. I have tried using only the official Divx & Xvid codecs. As far as CCE Basic goes, that's also another $60. Plus, you have to learn AviSynth.

The most baffling part of all this is that my 2-pass used to work on these same exact files with TMPGEnc Plus. It seems like some configuration problem, but I haven't the slightest clue as to what. Does anybody know what's going on? What configuration settings affect 2-Pass VBR but not CBR or CQ? Furthermore, what configuration settings only affect TMPGEnc Plus and not other encoders?

Does anybody have anything for me?

This is an example of one of my most recent encodes. I did 300 for the min, 2450 for the average, & 4600 for the max. It's almost as if it is degrading the picture on purpose:

Have you tried contacting Pegasys ?

Do you think posting this many times is going to get an answer quicker ?

[Gazorgan]

Reboot.
Uninstall TMPGEnc.
Reboot.
Remove the old TMPGEnc folder.
Re-install.
Re-boot.

Nearly always works. Of course re-formatting C should fix it also. Maybe you have a corrupted build?

[aamir12345678]

Thanks for your "helpful" reply, Jimmalenko. I have contacted Pegasys. They simply give automated responses. They're not very helpful, and I tried their suggestions. If you don't like my posts, just ignore them & move on. Bye.

[aamir12345678]

Gazorgan, I downloaded this TMPGEnc 2.521 from Pegasys's site.

[jimmalenko]

Thanks for your "helpful" reply, Jimmalenko.

The pleasure was all mine.

I have contacted Pegasys. They simply give automated responses. They're not very helpful, and I tried their suggestions. If you don't like my posts, just ignore them & move on. Bye.

Thanks for the update. You have never mentioned in your myriad of posts about this problem that you have actually contacted them. Now I know.

And as for ignoring your posts:

Do not post the same topic on several forums.
Please do not cross post, once is enough.

Is there something in this that I am missing ?

[aamir12345678]

For your information, I did not mean to crosspost. I originally thought the problem was with Divx or Xvid, so I posted in Newbie Conversion. I have now learned that the problem is with any file that I encode with TMPGEnc with 2-pass, so I thought it better if it would be in General Discussion. If you have such a problem, go to my other posts in Newbie Conversion or elsewhere & either delete them or lock them. I won't post this anywhere else. I will just wait for a reply here. Sorry to disturb you so much, Officer Jimmalenko.

[jimmalenko]

For your information, I did not mean to crosspost.

Well, you did post twice at least, whether you meant to or not.

"Officer, I did not mean to speed"
"OK I won't give you a ticket, Ma'am, if you didn't mean to"

See how lame that sounds ?

Sorry to disturb you so much, Officer Jimmalenko.

I have no problem with 95% of posters here. I have problems with those that jeopardise the future of this site. Rules are made for a reason - this site is surviving on the barest of legal grey areas and the last thing all of us need is for this wonderful tool to be shut down. If you appreciate the help (aside from all the jibes) that you get here, please pay a little more consideration to the site rules.

Preach over.

[aamir12345678]

Look I don't have a problem with you shutting the other posts down. In fact, if I could delete my own post topics, I would. If you are so troubled by this, please have the mods shut my other posts down that are too similar to this one, but not this one. This is the one I am going to stick with. I'm not asking you to "forgive" my speeding ticket. When the mods see a cross-post, they simply lock one of them; they don't give annoying, sarcastic, provocative lectures about how people like me are ruining this site. It was an honest mistake, and I'm sorry; just lock or delete the other posts too similar to this one and get off my back. You're making things bigger deals than they really are. I'm getting the feeling that your "advice" is not meant in general. Seems you are getting personal. Did I do something to you that I don't remember?

Now, what you've actually done is not useful. If you would have just reported my other post topics to the mods, they would have locked them and this would already be over, but you insisted on coming in here & sidetracking my post. Now, if someone really has useful tips for me, they will be annoyed by these long paragraphs. You could have PM'ed me. You are not a mod. You are just annoying people (not just me). PLEASE, JIMMALENKO, IF YOU HAVE ANYTHING FURTHER TO SAY ON THIS TOPIC, DON'T REPLY HERE. PM ME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[aamir12345678]

Does anybody have a clue why the TMPGEnc's 2-pass is not working with any & all videos that I try to encode?

Again, what configuration could possibly affect only the 2-pass VBR & not the CBR or CQ & only affects TMPGEnc and not other encoders?

Any help would be greatly appreciated. Thanks.

[Gazorgan]

It can be a lot of things. Try an older version of TMPGEnc. It can be what service pack you have, or some other program playing DLL hell. TMPGEnc error problems are actually common, and there's guides just for them.

Try formatting and fresh install of XP. Then intsall TMPGEnc and try it. It should fail 100%, you have no AVI renderer installed. Install FFDShow and see how that goes.

Speaking of AVI's, do you have the problem re-encoding anything else? On old VCD or DVDR you have? You may have simply fubared your AVI codecs, in which case, re-isntalling the right AVI codecs will fix it.


You should only need to install the following:

AC3 Filter (free)
MPEG2 codec (free)
MP3 codec (LAME is free)
FFDShow

That's it. If you encode to XviD or DivX then install Xvid (RC4 is latest build?) or DivX 5.0.5 or 5.1.1 (5.1.0 had issues?). That's it. Maybe OGG-Vorbis and H.264, but that's it.

Yes, I did try formatting & then encoding. It did not work. I also tried doing an old VCD. It didn't work either. So, you're saying it could be a .dll conflict? I'll check some stuff out. I'll also try ffdshow. Let you know if it works. Thanks.

As far as the older versions go, they will give me the bitrate I ask for most of the time, but they achieve more of a CBR. In other words, the bitrate is not varied by more than a few hundred kb/s throughout the whole video. The newest version analyzes the video properly & allocates the bitrate properly, but it seems to be degrading the average bitrate for some reason. If you look at the .log file, you see that it displays the right bitrate (based on the average I asked for) where it says "Req Bitrate" for the GOP, but it gives a significantly lower value for the "Current Bitrate" for the GOP.

Why is it degrading the average bitrate I ask for when it clearly knows it in the .log file????? This has got to be the most annoying problem I have ever come across with TMPGEnc.

JIMMALENKO, IF YOU HAVE ANYTHING FURTHER TO SAY ON THIS TOPIC, DON'T REPLY HERE. PM ME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

No need to blow a gasket, Charlie.

The only thing I can say about .dll conflicts is that it had the same problem with Windows 98 SE. Could the problems be about the fact that I have a permanent swap file? Does it have something to do with one of the services that are running? Is it a hardware problem? If it's a hardware problem, why do other encoders work with these same files?

[jimmalenko]

I'm starting to think it must be hardware related. That is the only thing you haven't changed. So many possibilities though - Could be CPU, could be RAM, could be mobo, could be video card, etc. Good luck !

[aamir12345678]

Why do the other encoders work then?

[jimmalenko]

Why do the other encoders work then?

Because the hardware conflicts with TMPGEnc.

It is quite feasible that hardware can conflict with one program and not another.

[aamir12345678]

Is there anyway to find out which piece of hardware is conflicting?

I've also tried to increase the average bitrate. After a few trial runs (long!!!!), I am able to get an average bitrate that I want through some calculations, but this is a tedious job. No setting can be different. You can't do a 1 min sample because it seems to alter the average you select differently based on the different motion in a movie. It may differ it 20% in one place and 10% in another and 40% in another. If I change the motion search precision to higher or lower, it will differ the bitrate differently. Further, when i do finally get the average I want, I find that some scenes go above my max setting. I set the max to 9100; it gives some scenes 10000. This is a serious problem. This is above the DVD Video Max. Does anybody understand what's going on here?

If it's a hardware problem, how can I find out which piece of hardware?

[aamir12345678]

If the some piece of hardware is conflicting with TMPGEnc, then why is it that CBR & CQ work correctly? I've tried a CBR & CQ of the whole video versus a 2-Pass VBR of a 1 min sample; the 2-Pass is still giving this problem, while the CBR & CQ work fine. If it is a hardware problem, why is it that only 2-Pass VBR is having a problem?

[jimmalenko]

Ever think that 2-Pass takes a lot longer and so therefore it could be a heat issue ? Still hardware related. The only way to test is to interchange parts, one at a time.

[RabidDog]

is there really a problem? or do you THINK there is a problem? your statement "

where it says "Req Bitrate" for the GOP, but it gives a significantly lower value for the "Current Bitrate" for the GOP.

Obviously most of the video will have less than the average bitrate because some of the video will have more than the average bitrate.

they achieve more of a CBR

This statement is pure rubbish the bitrate given out by various builds of the encoder will differ very little. It has simply had some bugs and optimizations done. Set up a new part and install things one by one, testing for three or four days btween each new program.

[aamir12345678]

RabidDog, I am sure that it is providing a lower bitrate for the final video. Not only does it say that in TMPGEnc's .log file that the average bitrate is less than the one that I set in the settings, but I have also taken the size of the output video and used a bitrate calculator to figure out the average bitrate of the resulting video. I am sure that there's a problem.

As far as the older builds go, maybe it was just my video or my settings, but I just threw that in to help someone figure out what's going on.

As far as the hardware problems go, I've never had a problem with overheating or anything of the sort. Encoding is an intensive task, but I have used TMPGEnc to encode using 2-Pass VBR before and it worked flawlessly. I just can't put my finger on what has changed hardware-wise or software-wise that is causing a conflict.

[RabidDog]

you arent using tmpgenc to encode into xvid or divx are you??

[aamir12345678]

No, from.

However, it seems that regardless of what I use for my Input (VCD, SVCD, Divx, or Xvid), I get the same problem.

Jimmalenko, as far as the heating problem, I've done a CBR of the whole 20 min video vs. a 2-Pass VBR of a 1 min sample, the CBR worked, but the 2-Pass VBR had the same result.
