Encoded DIVXMPG4 V3 AVI to Mpeg1. Result plays fine, as long as it is played from the very beginning. When fast forwarded/reversed, the audio is lost. Sometimes the video also freezes.
How does the CQ-VBR Quality Setting relate to the encoding process?
What is actually being changed?
Is there a method to determine the maximum bit rate, beyond which the video quality will not increase??? (assuming you know the max/min/avg data rate and frame rate of the source)?
Are you trying to find out a Way to figure out what the file size is going to be???If you are it is pretty hard to figure out....All the Quality slider seems to do is allocate more bits to the encodeing proscess so the higher the slider goes the More bits get allocated and the bigger the file size and the better the quality....
I am looking to optimize the quality of the encoded video, without wasting disk space. In the VBR-CQ mode we have already specified the minimum and maximum data rates. If the required video rate falls with the min/max, what does the Quality slider adjust? Pixels/frame? Spaitial frequency limit? Motion threshold?
I am happy to use multiple disks, I just don't want them filled with zeroes.
i have downloaded the TMPEG Enc. 2.57 but i can't convert any .mov-File of the Quick Time Player to MPG. I already downloaded the "QTReader.vfp" but when i converted the file to MPG the quality of the file is very bad.
what can i do?
I don"t think there is much you Can do ,if the QT Reader isn"t produceing good Quality that is the only remedy that Tmpgenc has for encodeing Mov files...You can encode it to AVI then to Mpeg, or you can use CinemaCraft, it supports Mov files, but the mpeg1 quality isn"t as good as tmpgenc but the Mpeg2 quality is better.....
I just had an idea yesterday and i was wondering if it would work or not. Lets say i was making a video that would play at 1500kbps. I know the source file plays at 524kbps so the quality would be better at 1500kbps. I also know the source file affects the quality of the output file. To make the quality best maybe i could encode the video at 5000kbps to get out some of the blockiness. Then i could reencode it down to 1500kbps with the source file at 5000kbps. Since the source file would be the nice 5000kbps video instead of thge 524 one the the 1500kbps video would be nicer when made from the 5000kbps video in comparison to the 1500kbps made from the 524kbps video. Would this work or not? I want to make the same size file video with better quality by using this process. hope you understand what i am getting at cause its kind of hard to understand.
I understand what you are saying but it doesn"t work that way, no matter what bitrate you encode the movie at the mpeg will not have the same quality as the source file,so if you encode it once at a really high bitrate the mpeg will have less quality than the source file then if you encode that at a lower bitrate it will loose even more quality..If you just encode it right the first time you will get the best results...
Yes It does, A encoded movie will allways have less Quality than the source, sometimes it Might not be noticeable to the Naked eye when useing enough bitrate..
You cannot make Gold from iron. Simple as that and that is more or less what you are suggesting unless you are some kind of alchemist.
As minion says you can't simple improve the quality by increasing the bitrate of the original. All you will end up with is the same crap looking movie, but encoded at a higher bitrate and larger file size. You cannot remove blocks once encoded into the movie, you may be able to reduce the effect with filters, but that is is.
If it was possible to do what you say then we could all encode our movies to a very low bitrate and thus smaller file size for archive purposes and then just re-encode to a higher bitrate when we need the movie to improve the quality.
Lower bitrate means less quality because of less data retained in the original movie. This data cannot be replaced and thus the original can't be improved by simply increasing the bitrate.
encoded a 95minute movie with CBR setting of 950kbps for videoa (from DVD2AVI project)and 244 kbps extracted Wav audio(used CLADVD to rip and frameserve)..TMPEGENC Wizard had preedicted 804MB disk...actual was 997MB!!! obviously won't fit on a VCD...
why is this off...
You are makeing a NON_Standard VCD so you have to change the "System Setting" to "Video-CD Non-Standard"...Go to "Settings" to "System" and change it to "VCD Non-Standard"...Tmpgenc will add padding to the file to keep it VCD Compliant unless you change the stream setting......At 950kbs the quality must be really bad, You would probably better off and happier about the result if you put it on 2 cd=r"s and raise the bitrate to 2125kbs, at least it will look good..
If you want to put Subtitles into a AVI file then encode it to Mpeg ,you will need something like "Virtual Dub" with the "Subtitle Plugin" and Frame serve the AVI with the Subs to Tmpgenc....You can get Virtual Dub at "WWW.Virtualdub.Net"
if you want to produce a svcd there is another option beside encoding the subtitles into the picture.
svcd allows for up to 4 subtitles that can be chosen by the player.
if that is what you want, you need bmp's an a subtitle scipt and mux the subtitles into the programstream.
tmpg cannot do that, but with maestro sbt and winsubmux you can do it, extensive guide on subtitles for svcd you can find on www.vcdhelp.com or www.doom9.org
That error is usually caused by Corrupted frames in your source file, or you can get that error if you do anything with your computer besides encodeing, even haveing the screen saver come on has been known to give you this error..If you keep getting the error there is one way to fix it but it will make the encodeing take a lot longer...Go to "options" to "Enviromental Settings" to "CPU" and "UN-Check" the "SSE & SSE-2" Boxes, then go to "settings" to "Quantize Matrix" and "UN-Check" the Box next to "Use Floating Point DCT"..This will Turn off the "Floating Point" system but it also disables the SSE and SSE2 optimizeations which will slow down the encodeing....
...or if you want to fix the bad frame and encode with all the optimizations you can use avidefreezer ...go to the utils section which also has a a guide
I have been trying to encode a DVD Rip. I did it once but screwed up the aspect ratio. Other than that it works fine. I have tried to do it again ( fixing the aspect ratio ) but now I get "MPEG Audio Stream errors" at random points. I have tried 3 times and have gotten this error at three different places. What gives? I know the source is OK since I encoded it before. The original also plays fine in Windows Media Player. The source has not changed so wht gives.
Also, this program really needs some work on the error handling and reporting. I have gotten alot of errors where an error box pops up with 2 numbers, none of which mean anything to me. There should be a switch to turn off these useless error boxes and log the errors instead.
What format is the Audio in???Have you tried the external audio encoders for Tmpgenc ,like Toolame, or SCMPX????or you can just use a totally different audio encoder and mux the audio and video together...You can even use "DB Power Amp" to encode the audio to Mp2, there are 3 differant mp2 codecs for it and it is Free....
Thats all fine but doesnt explain why the errors occur at different places and why did it encode without errors before? I just reied again and got the same error at yet a different place. There is a problem with this program.
okay I have a SVCD compliant mpg file which I want to convert to a VCD mpg file, since my DVD player does not support SVCD files. The thing is when I click on the browse button next to video source on the main window - when I click ok after selecting my file - it gives me an error msg saying the file is not supported - surely a basic thing like this should be support, shouldn't it?
Encodeing Mpeg to Mpeg isn"t a basic thing ,Not many encoders support Encodeing Mpeg files to Mpeg files..But to your problem, you need to have a Mpeg2 decoder installed on your system to load Mpeg files into Tmpgenc, if you Have "Power DVD" installed on your system then you will have a Mpeg2 Decoder,Sometimes if you "De Multiplex" the Mpeg file you can load in the Mpeg Video file into Tmpgenc, and Just encode the video Cuz The Audio is allready in the Correct format, then after the encodeing is done you "Multiplex" the encoded mpeg with the "De-Multiplexed" audio..But if you still can"t get Tmpgenc to Load the Mpeg file use "DVD2AVI, you load the "MPV" file into "DVD2AVI and make a "D2V project File and use that as the video source in Tmpgenc, then encode it without the audio then after, multiplex the audio and video together.The DVD2AVI way works all the time...
there is a trick, to fool the dvdplayer, you can use the simple multiplex option in the mpeg tools of tmpgenc to make a mpeg2 that has vcd sequence headers. then burn a vcd with that file.
The player thinks it is a vcd, but it will choose the appropriate decoder when playing the AV. And since your dvdplayer has a mpeg2 decoder (dvd is mpeg2 too) this should work
However, this won't work on all player (although i only encountered 1 so far)
converting the headers doesn't take to long, because the videodata doesn't have to be reencoded, just new headers written. most people refer to this as the "header trick"
I downloaded a video and used Virtual Dub to extract the audio to a WAV. Unfortunately, the resulting WAV file is jumpy enough to be totally unintelligible. I actually neglected to test it before encoding with TMPGenc, and the CD's (burned with Nero) were great visually, but unintelligible, sound-wise. Both of the original *.avi's played well on my computer, though.
I looked at some of the AC3 posts that a search of this site turned up, but I am too new to this video burning thing to really understand what I need to do, to correct this.
Codec Viewer (that I only found, thanks to a guru on this BB!) reports the following:
Mux is the same as "Multiplex" which is the joining of a Video and audio file, and "de-mux" is the same as "De-Multiplex" which is the seperateing of Video and audio streams..In the "Mpeg Tools" there are "Muxers" and "de-muxers"...It seems that the audio in your Divx file is "AC3" which is "Dolby Digital" you need to extract the audio and encode it to Wav...Look on a search engine for "AC3 Decode" and try to use that to get a wav file out of your Divx file...
THANKS Minion! I think you were the poster that led me to the Code Viewer. Can you point me to a REALLY SIMPLE AC3 decoder? I looked at the ones turned up in a Google search, and they seemed a bit complicated.
Also... will I still use TMPGenc to encode, after I extract the audio with the tool that you recommend?
Yes you would use Tmpgenc to encode, I haven"t been able to find an easy AC# decoder for you yet, AC3 is sort of hard to work with cuz there aren"t a lot of programs for encodeing and decodeing AC3...An Easyier one is "Soft encode" but it is hard to find and Expensive to Buy....
In response to the AC3 decoding process, I have found a really easy way to manipulate a few things to get it to work. First extract the audio from the avi file using virtualdub (just extract into a wav) then rename the extension to ac3. After all that is complete run you decoder, i use ac3decoder 1.0 really basic but it gets the job done, and access your extracted wave (ac3) file and decode.... GOOD LUCK!! zenxeon
on doom9 you can find a good ac3 coder/decoder (that's where codec comes from) bbsweet.
it allows for decoding ac3,mp2, mp3, aif and god knows what into ac3, mp2, mp3, aif, 5.1 wav and god knows what.
there is a nice gui for the package as well, BeSweetGUI 0.6b51

I encoded some South Park and Simpsons episode but they have tons of block noise. No matter how much I increase the quality and bitrate the blockiness doesn't go away. Is it just because the movies are animated? How can I get rid of the blocks?
Is the block noise there on the source file ?
If the source is blocky you can try using some of the filters to clean the output up, but ultimately you need a good source to produce really good output.
If the block noise is not present in your source file and is not present in the output when viewed through a software DVD player like Power DVD, it may be that you are burning at too high a speed, or that the media brand you are using is not fully compatible with your DVD player.
I am using tmpge 2.57 and everything seems to go fine with turnning avi to mpeg, i go to load and selet video cd (ntsc) and then select the movies i want to transfer and then i use easy cd creator 5 vcd program and i have an apex dvd player that plays anything, it plays perfect for about 20 to 25 minutes and then slowly gets choppy and then stops. Does anyone have any advice for me, i would much appreciate it.
Its not the dvd player, it does it when i play the recorded cd in windows media player to. I gave a copy to a friend and it did the same thing playing on his computer when he played it, it would play fine up until about 20 to 25 minutes and I have recorded other movies and it does the same thing. Does that help you any.
All I can think of is to re-encode the file and see if it looks better this time but if it does the same thing at the same time then it is probably a problem with the avi file..
