Wondering if someone could give us some pointers, I've got ashy's templates, had a quick nosey and was a bit puzzled. The quality was set at 1000 with 0 as minimum bitrate and 3500 as maximum. Could someone tell me wether my assumption is correct, that its up to me to decide through testing ( a minutes worth of film) what to enter as the minimum bitrate. I thought I'd be clever and use the bitrate calculator to work out how much it would be for CBR and then take off about 150 to compensate for a film with a reasonable amount of fast scenes. Unfortunately I regulary go over 750 mb and have to start again. Could someone tell me wether I'm on the right lines and what the quality setting is all about. I did a a test on star wars (136 mins) and decided that each minute needed about 10mb (1500/136), I changed to bitrate to 1200 (bitrate calc said 1367 for 136mins on 2 80min cds with 224 audio). Did a test for a minute, it seemed fine but in the end both files still ended up 850+mb , another night wasted. Any tips or examples would be much appreciated. Maybe I would be better sticking with CBR just because its easier for a beginner. Not very positive I know!!!
The minimum bitrate he set it at is right, haveing a "0" minimum bitrate is a good thing if you are looking for your file to have a small size,the encoder won"t actually go down to zero bitrate but it will go close for frames that are black or just have credits on them,haveing the bitrate set at zero minimum and 100% quality lets the encoder choose over a wider range the amount of bits to allocate to each frame.You dont want more bits than needed to make up your movie, you dont need 10mb per minute if your encodeing the credits at the end of a movie or scenes with no movement ,and that 3 minutes of credits and scenes with no movementin each movie can really add up, but for scenes with lots of movement there is enough bits there to do the job...
Can anyone help me figure out why the sound cuts in and out on the vcd i made?
I encoded the divx avi to mpeg1 and it sounds fine if i play it on my pc but it sounds very bad after i put it on disk. I'm pretty new at all of this, but it is the 1st time I've encoded a divx and the 1st time I've had a problem such as this.
THX
It could be the format of the audio or the frequency or the bitrate of the audio.For the audio on a vcd to play correctly in your dvd player the frequency has to be 41000hz, and the bitrate shouldn"t be lower than about 96kbs...
I had hopes of transfering all my hi-8 tapes to dvd. After suffering the pitfalls of editing mpegs, I went with Studio Deluxe and edited the captured avis instead. However, in using TMPGENC in wizard mode, I'm getting audio sync problems. Win Media says its a shorter video (1 hr 5 mins) while it continues to play past to the end (1 hr 30 mins). Because of this I can't check to see if the mpg is out of sync or it is in the burn process.
Then I proceeded to use TMPGENC to convert the single avi into three segments and subsequent using mpeg tools to merge them into one. While the encoding was far, far, far, far faster (5 hrs versus 30+ hrs on my 1.5 g, 512mg pc), I'm still getting sync problems.
Anyone has any solutions? I know my hi-8 tapes are not that great but there has to be a way to fix this.
What type of de-sync do you have?Does it start out in sync and get worse or does it start out of sync and stay the same amount out of sync the whole way through the file? cuz each type of de-sync would have a different solution to fix it.In most cases of de-sync when it comes to captured files,is caused by dropping of frames which in turn makes your avi file shorter than your audio, so what you have to do is extract the audio from your avi file and measure exactly how long it is and then take your video and mesure exactly how long it is, if you cant find out how long the video is you can count the number of frames in the file and then do some math to find out how long it is, then you will have to use a audio editing program like "cool edit" and shrink your audio file to the same exact length of your video then encode the shrunken audio to mp2 and multiplex it with your video file..This is a long and complicated way to do it but it works and it is quicker than re-encodeing and still haveing the same problem...
Thanks, I'll try that. That certainly looks like a viable option since mine starts out fine and gets out of sync by the end of the video.
I think I'll abandon my latest attempt which was to capture the video into four separate avis, convert them to mpg separately and subsequently merging them together. However, what can I use to separate out the audio part of an avi and where can I find the shrink function in Cool Edit Pro?

To find the function were you stretch the audio file is under "transform" then to "time pitch" and then change the time to the length of your movie ... I think this probably the only way to fix that type of de-sync but you can try to alter your captureing technique to drop less frames and therefore create less of a sync problem,are you captureing useing a codec? cuz maybe captureing to uncompressed avi would be better, and instead of editing your avi files together you can frame serve them from "virtuadub" and seamlessly encode them into one mpeg then you wont have to worry about joining your mpeg"s or avi"s and it might help you de-sync problem..
I must be doing something wrong, I checked and found the difference between the video and audio to be 8 secs off by the end of the unedited 2 hr+ capture. After shrinking the audio and using tmpgenc to create an mpeg from both files, I find it shrank too much, audio before video sync. I need to be more accurate I guess.
BTW, do I shrink the audio before or after I edit the avi?
You shrink the audio after you have finished encodeing the avi (with out audio) to mpeg, then you see how long the video is and compare it to your extracted audio, then shrink it and encode it to mp2 then multiplex it to your mpeg file..
Those "Horizontal lines" are called "interlace lines" you can try to make them look not as prevailant by useing the "De-interlace" setting in the "advanced" tab under "settings".Just double click on the "de-interlace" filter and a window will pop up and there will be a drop down menu with a whole bunch of different de-interlace options, move the slider till you get to a part where there is a lot of lines showing and go through the settings till you find the one that seems to work best.....
Hy, you have to open tmpgenc and the "mepg Tools". Choose " merge & cut" and load the movie you want to split with the "add"-button. No click "edit" and you'll get a new window. Now you have to choose your start-point, using the bar under the movie-bar. The click the "["-Botton. Go to end of the first part and click "]". Now only "OK" and choose the Output. "run" and it will work. Now you only have to do the same with the second part.
You can multiplex "ac3 dolby digital" with an mpeg2 file but you will have to use a different multiplexor, the one in "bbmpeg" supports "AC3" audio ,But if you are trying to add "DTS" "Dolby Theater Sound" there is no way as of yet to add this format to mpeg"s with any software i know of..
What Minion says is possible, but the file will only play correctly on your PC. SVCD or VCD doesn't support Ac3 audio, so it is most likely you won't hear the audio on your DVD player.
Most programs like DVD2AVI and VOB2AUDIO can downmix this Ac3 track to Dolby Prologic anyway, so you are still getting Dolby surround sound, but only the Prologic version not Dolby digital.
ho un problema con tmpeg sopra descritto

ILLEGAL FLOATING DECIMAL POINT CALCULATION ORDER
qualcuno che sa l'italiano puo spiegarmi come risolvere il problema?
I am new to TMPGEnc and trying to encode a complex project a little over 2 hours long with several hundred clips for use by DVDit!PE or ReelDVD. I followed the Rui del-Negro tutorial and used the DVD NTSC settings with 2 passes, average=4200, max=7000, min=2000, highest quality, I=1, P=3, B=2, GOP max=15, output closed GOP disabled, detect scene change enabled and force picture type disabled. On my 2.4 GHz P4 with 512MB memory, the encode time (it's still going!) will be over 50 hours. I have a few questions for the many experts I've seen on this board:
Is this encode time normal?
If not, what did I do wrong?
If so, are there things that can be done to shorten it without reducing quality much?
For a project with lots of clips and scene changes, what settings would likely produce the best quality?
Thanks for your help,
Two hours of video encoded into mpeg on your system shouldn"t take more than 6 hours in 2 pass mode,How are you encodeing these several hunderd clips?Are they avi files or are they bmp images?are you encodeing several seperate clips and joining them with the "merge & cut" feature..I have no Idea why it is takeing so long but you can get pretty much the same quality with less than half the encodeing time if you used a "CQ" encodeing method..But try downloading and installing "tmpgenc" again and see if that helps cuz with you super fast system you should be able to encode 2 hours of video less than 6 hours ,hell on my 800mhz system I can do 2 hours in about 12 hours and that is a little long for me.....
Thanks for your (encouraging) reply. The program I am encoding was prepared in Premiere 6.01. It consists of a lot of video clips (with audio) put together in Premiere with a large number of transitions. I am using TMPGEnc through the AVISynth frame server from the Premiere timeline. It took Ligos about 9 hours to encode it and it did a pretty good job (though the bit rate I picked produced a file that was too large). I don't know why it is taking so long either but it now says it will be about 54 hours (the time remaining value has been useless - it first said it would take 15 hours and has steadily been losing time!). I am concerned that the combination of the GOP structure and the bit rate made it a difficult combination to encode. I may also have made some other error in the parameters but it does seem to be running normally. Any further thoughts on what I did to make it take so long?
I think that you long encodeing times are due to the frame serveing through avi synth,frame serveing allways make the encodeing take twice as long, maybe try setting up your frame server again or try frame serving with virtua dub,but if you can uncompress your avi file and load it directly in tmpgenc you will get faster results and im sure you would save time even takeing in to account the time it takes to uncompress your avi file or compress it into a direct show format or a vfw format..
If you are using the 'Highest' quality setting in TMPG, this is one of the reasons it's taking so long. The 'highest' quality setting always drastically increases the encoding time. You could halve that time by reducing it to just 'High' and it won't make a jot of difference to the image quality.
Really, I have done tests regarding this and the 'highest' quality setting has no image quality advantage over 'high' quality except for the fact it doubles your encode time.
Thanks, I'll give that a try. It ended up taking 55 hours and seems successful but the quality was not much different than the Ligos full-version plug-in for Premiere which did it in under 9 hours. I still wonder if there are other settings I made that caused it to take so long.
Is there anyway to resume a partially encoded file? My computer has a nasty habit of locking up and shutting down when it sleeps for too long (a problem with Win98se). Being that it takes a long time to encode AVI to MPEG, I never seem to finish a project. I keep restarting and overwriting the last attempt. Is there a way around this?
Also, (this is my first attempt at this, by the way) I noticed that movie length stated by the program just befor I start the encoding is much longer than the actual length of the movie. As stated above, I've yet to complete a project, but is this normal? Does it mean anything?
I'm a novice at this myself, but are you saying that your computer goes on s "standby" mode if the keyboard or mouse is not touched after a set period of time? When I started using napster 2 yrs ago and had only a 33kps modem I was lucky to get even a four minute song before the download was terminated by my system going to "sleep". I had to go into the Windows "settings" and adjusted a couple of things (can't quite recall what at the moment) so that the computer never shuts down automatically.
Sorry if I completely misunderstood... I'm basically here looking for scraps of knowledge myself! :-)
"Is there anyway to resume a partially encoded file? "
Yes, sort of. There may be a more elegant way to do it, but this will get you by for now.
Preserve the partial file by renaming it or changing the name of your output file. Use the SOURCE RANGE feature to find the last frame number of the partial file.
Then use it to find the same frame number in your source file and set that as the start point of the encoding process. Actually you came input the frame number directly into TMPGenc and press the MOVE TO START POINT to check it.
If you need to you can merge the two encoded files later, using the MERGE/CUT feature in MPEG TOOLS.
Also:
To prevent your system from going to sleep mode in the middle of the encoding, go to the Power settings in the Control Panel and change the settings to make sure it doesn't go into standby while you are encoding.
Also, You might also want to change your screensaver. You don't want one that is using your resources. I have mine set to just blank the screen.
You might want to check the settings in your system's BIOS settings to see what the energy settings are set to.
had 5 min. of bad video at the very last of the vcd. I cut the bad sectors then took the 5 min from the original mpeg not formatted to vcd however when I finished multiplexing after cutting there was no sound . This is the same mpeg I used to create the vcd.
Why did you need to multiplex it after cutting?If you would have cut it in "mpeg1-vcd" mode you wouldn"t have had to format it to vcd by multiplexing ,cutting does the same thing,it attaches vcd headers to the mpeg file....
Curious? If your source file was already an MPEG then why did you re-encode it?
What do you mean multiplexing after cutting. What did you multiplex, the last 5 minutes with the rest of the MPEG?
If you are trying to join the two together, you should have used the Merge&Cut feature not multiplex. Multiplexing just combines 2 streams into one, such as audio and video stream. I magine twisting 2 pieces of string together, this is what multiplexing does.
I think I probably used the wrong term I said miltiplexing because at the end of the merge and cut process tmpg tells you it is multiplexing. I did use the merge and cut .The original file is not a vcd format I used it to create a vcd and there was a crash at the very last ofit . I took the one formatted for vcd and cut the bad sectors , I took the unformatted video and cut out the sectors that I needed to finnish the vcd. however afterusing mergeand cut there was no sound
First you have to download the "Tmpgenc 2.54a Plus" version ,not the demo version,click on the banner below to download the "Plus" version, Then go to "Help" then "Register".....
I tried to use TMPGenc to convert my AVI files into MPEG files, however when I browsed the AVI files in the video option of the TMPGenc program, it prompts "cannot open file or file unsupported"; the same AVI files can be browsed in the audio option of the program though. My AVI files were taken by a digital camera "Fujifilm z6800", They can be played normally in Windows Media Player... I guess there is no problem with my AVI files? then what's the problem? Why's it not supported by TMPGenc program?? or what can I do to fix it? Please help!! Thank you.
Look at post "8512" for an answer,but if that dont work then it might have to do with a codec if you used a DV codec to capture to your computer,"Tmpgenc" is only compatable with "Open DML Direct Show" formats and "Video Fow Windows(VFW)"formats, so to get unsuported avi files in you would have to de-compress them to uncompressed avi or encode them to a supported format..
