I have a avi file which has an unsupported audio format. I've extracted the audio using virtualdub, and use that as the audio source when encoding a vcd from original avi file. Problem is the sound is about 1sec out. How do you remedy this?
Encoded using constant bitrate, and the problem is less noticeable than 2 pass or CQ. Is the Rate Control Mode the cause of this problem?
The sound in the original avi file when played in WinMediaPlayer and WinDVD is fine, no sync problems.
Well If you play your mpeg files in "media player" it can play your files out of sync, but if it is out of sync the same amount through the whole movie then you can fix it by multiplexing the audio and video with "bbmpeg" or "mpegvcr" cuz they have a feature in there multiplexor that lets you start the audio or video first so you can sync your file......
i have downloaded the tmpgenc 2.56.39.143 and can't figure out how to convert my avi movies to mpeg 1. I am trying to load the avi file and i am getting a message "can not open, or unsupported" I am able to convert the sound but not video. What do i need to do?
You need to raise the priority of your "direct show file reader" you do this by going to "options" to "enviromental settings" to "vfapi plugins" and raise the priority on the "direct show" to "2".....
What gives better quality? Constant bit rate or Constant quality? Basically I am
trying to encode a movie into a standard mpeg file(not vcd standard, not dvd standard etc..)that can be played with any standard file player. So I am wondering what would give me the best quality overall? I am buring the file to
disc(700mb). I notice that i can set higher bitrates in the CQ setting then i can in CBR and get a smaller file. Ex. i can set the min and max in CQ at 1600 kbits per sec and the final size of a 50min movie is a lot smaller/more fittable on to a 700mb disc than the one that was encoded using 1600 bits for CBR. In order for the file using CBR to come out at nearly the same size as CQ or fittable onto one 700mb cd i had to set the bit rate for CBR at 1500 kbits. So is CBR file bigger because it's got better qaulity? I can't tell when i compared the two movies because both of the movies don't really contain a lot of high motion scenes(I encoded the same movie twice using the same audio settings) Any insight would be great thanks.
Cq is the better format but you had the bitrate settings set way to low to give you the best quality ,if you are useing standard vcd resolution 352 by 240 you can set the bitrate to 5000kbs max and 500min and the quality to 80, and un-tick the enable padding, and under the system settings put it at vcd non-standard ,I was able to get a 1 hour 50minute in fairly good quality on a single cd-r, the quality wasn"t what I was used to cuz i usually do high rez xsvcd"s but they looked good rof putting a whole movie on a cd-r when I usually put them on 3 cd-r"s......
Thanks for the advice Minion, but i have one more question, Is there any way to sorta figure out how big a file is going to be if you use CQ? Is there any way to sorta determine the size outcome after setting the min and max settings? Or do i bascially have to go through trial and error to figure out which is the correct bit rate? Thanks
If you are only using a software player, what is the point in encoding to MPEG at all? If you have no intention of making these files into VCD or DVD then you would acheive better quality and smaller file size encoding to DIVX.
I could do divx for a smaller file and better qaulity but i was thinking about lending it to my friends so they can watch it also. My friends however are a bit iffy about installing non-commerical items on their machines. So unless I try forcing divx down their throats i don't think it's going to happen lol.
Still i'd like to know if you could calculate the final file output size when using CQ.
What do you mean by non commercial? Do you mean you friends won't use a codec you don't have to pay for.
If that's the case they should wipe off half of the codecs that are already installed on their machines because I bet most of them are using some sort of non commercial codec already, for example what sort of MP3 codec do you friends use?
Also if that's the case then why don't you use DIVX 5 pro. This codec is commercial.
Any to answer your question, the way I do it is to encode a typical scene in the movie for a minute and then multiply the resulting file size by the amount of minutes in the film. This will give you an average size for the film and something to aim for with the bitrate.
To make it more accurate, encode say a five minute sample then do the math. This will give a more accurate representation of the final output size.
>What gives better quality? Constant bit rate or Constant quality? Basically I amtrying to encode a movie into a standard mpeg file(not vcd standard, not dvd standard etc..)that can be played with any standard file player. So I am wondering what would give me the best quality overall?
To reply to the origional question. The Constant Quality (CQ) setting is by far the best, as it gives the best quality for the final file size.
You could go down the DivX route, but if you want an mpeg just for playing on your PC, I'd experiment with the CQ settings, 'till you arrive at a quality vs file sizethat your happy with.
Hoorah we finally agree on something, so you DO have some worthwhile advice after all.
I wholly agree that the CQ method is by far the best and will give the better quality vs file size output.
Well sort of, you can use the "clip frame "feature to cut the bottom or top or sides of the frame off so depending on how big the writeing is you can do it, but you might not like the effect of haveing the frame cut off at the bottom or top......
I downloaded and installed TMPGEnc 2.56.39.143. I then tried to use an AVI as the video and audio source. The error message was "can not open or unsupported".
Go to "option" to "enviromental settings" to "vfapi plugins" and raise the priority of the "direct show file reader" to "2" this should get your avi file loaded....
When i convert an .avi file to an mpg file i also have no sound in the new file.
I tried this with different avi files, so i'm sure it's not an unsupported sound format. What could be the problem?
Dmitriy privet
It should work. I tried previous version and now trying last version - it's work.Check your audio after capture and after editing.
Sergey
As a general rule it is allways good to extract the audio to a wav file and encpde the wav as your audio source cuz in a lot of cases the avi file has a unsuported audio format, you don"t need to re-encode your file just extract the audio then encode it to mp2 then mux it with your mpeg file.....
easy, just make a copy of the avi file in another folder and rename it as a sound file,,,wav, mp3, mp2, etc. than just put that as ur audio input!
works for me =)
I read a few guides on frameserving files to tmpgenc, and they all said to fire up virtualdub, start a frameserver, save to outfile.vdr, and then load the outfile.vdr as video source in tmpgenc. However this does not work for me, tmpgenc says it's an unsupported format...
I'am new to this so please don't bash me.
My goal is to capture our familie movies and save them to vcd/svcd.
I use a dc10+ capture card and it all works fine .
Then i want it to convert it to mpg , i know that the movies are coded in mjpeg av' , but tmpgenc wont accept them and an error occurs : is say's that it is unsupported. I've read to thrugh the BBS and saw that i had to raise the priority of 'AVI VFW compatibility reader' , stil i get the same message only it takes a lot longer to display it , so there is something happening. please help me .
specs :
Windows XP
Studio 7
tmpgenc-2.5631.143
amd 1900+
265 ddr
geforce2 pro
dc10+
One piece of advice is to ignore "chumps" who give useless advise,and are so clever,that they can't get XP to work!! Hang on in there buddy and hope for a reply from Ashy or Minion. They'll have something usefull to say.
i had the same problem and minion left me a message follow these instuctions and you should work ok
"minion message"
You are probably getting a "cannot open or unsupported format" Error when you try to load your file, to Fix it , go to "options" to "enviromental settings" to "vfapi plugins" then raise the "direct show file reader" to "2" by right clicking it and selecting raise priority,this should get you file loaded..

thanx foxx for the help but it didn't solve the problem :raised 'direct show' to 2 ,restarted the program but i still get that error. That is the odd thing about it because i've read it already in the forum and tried it without succes.
Any other ideas ? Ow help ...
Well I guess if you tried all the usual tricks then I don"t know what could be wrong, but You can try to capture to a different avi format ,one that is more compatible with tmpgenc(mjpeg usually works)like a "VFW" format or a type2 dv format, or you can try to frames serve the mjpeg to tmpgenc with virtual dub, but becides this I don"t have a clue what is going wrong ,maybe Ashy has a clue......
Something else : the other strange thing is that when i raise the 'direct show file reader'to 2 and try to reload the mjpeg avi from the dc10+ , something is hapening , the program doesn't respond and my harddrive sows action for about 10 seconds or more. this doen't occur when i prioritise something else , then the warning ( ..., unsupported) pops up instantly.
Mayby a bug ?
have you already tried using an uncompressed codec?
or if you need to use compressed, try the YU9V or Huffy codec
i know TMPGenc supports those easily
if you dont see a way to capture using other codecs and it only lets you choose that MJPEG one, go to www.vcdhelp.com and download the Huffy codec on their tools page
and guys honestly, from personal experience with this card and OS
i strongly urge you to not use XP, you will have even more compatibility problems down the road. Win2K works with it all superbly!
If you can get your file loaded into "virtual dud" then virtual dub can frame serve the file to tmpgenc(frame serveing is sort of like fooling tmpgenc into thinking the file is of a supported format) go to www.virtualdub.com and read up on it, but if there is any way to capture to a different codec or to un-compressed avi files then that would be the best bet, I wouldn"t trust a product that only lets you use one format to capture to cuz if the only product that can decode it might be another one of There products...but here is a last ditch attempt to help out, do you have the proper codec to decode the mjpeg file cuz with out it tmpgenc can"t read the file......
I've downloaded 'TMPGEnc-2.56.39.143-Free-VFP.zip' and installed it correctly but that didn't help. I've also tried file-servering but then i have interlacing problems : in a movie frame you see also the frame from before displaced . Dou think that with win2002 it all works ? capture in mjpegs and load it directly in TMPGEncwithout any problems ?
Disable the Directshow plugin and increase the priority of the VFW plugin to 2.
If that doesn't work try installing another MJPEG codec. The Virtualdub site has links to other vendors MJPEG codecs.
may i ask Woutman, why are you so fixed on using the MJPEG codec?
There are better codecs out there
and when/if you have interlacing problems you can overcome them in TMPGenc Settings in the Advanced tab
select non-interlaced as your source then double click Interlacing in the bottom section and choose one that best suits what you are doing, you can see the preview when you choose
You are correct the interlacing problems could be corrected with TMPG and are probably due also to the wrong field order being selected.
Does your card not allow you to select a progressive output rather than an interlaced one?
I read a few guides on frameserving files to tmpgenc, and they all said to fire up virtualdub, start a frameserver, save to outfile.vdr, and then load the outfile.vdr as video source in tmpgenc. However this does not work for me, tmpgenc says it's an unsupported format...
Your avi file probably has an unsupported audio format, you need to extract the audio from your avi file with "virtualdub" to a Wav file and use that as your audio source...
Basically these are my problem,
1.) Tmpgenc seems to hang during an encoding session(the file is only 48mins long in play time.) It hangs when it reaches the halfway mark sometimes.
2.) If above doesn't happen then sometimes Tmpgenc will reboot my system when I am encoding a big file(600-680 megs)
3.) I encoded 3 mpeg files using Tmpgenc. All three files are fine and working
I merge all 3 files in to one giant mpeg file. The mpeg file is fine.
I try to split the file into 2 files so one half fits on one cd and the other half on another cd. The first split comes out fine but when i go for the second
split tmpgenc freezes totally. Even after a complete reboot this happens. I try
moving the entire mpeg file to a new drive, same thing happens, I move tmpgenc to another drive, same thing happens.
My machine:
Win98 second edition (unpatched due to reinstall)
128 rdam
Ati all in wonder radeon 32ddr
sound blaster live 5.1
P4 1.7 gig
60 gig maxtor hard drive partitioned into 5 drives (all
vob + mpeg files are stored on a 15 gig drive). The entire drive has recently been reformatted
8x cd burner
16x dvd player
Because of this problem I even tried the following:
Most of anything in my startup is closed prior to encoding
icons in my systray are removed prior to encoding
My virtual memory is set to my entire C drive which is 1.4 gigs.
Same things happen.
The only time that the hanging+rebooting during encoding does not happen is when i encode files that are only 27mins to 35 mins long in play time.
Can someone give me a clue as why this is happening? Has anyone seen these symptoms before? Thanks for any help
Try raiseing your "Virtual Memory", and for the merge and cut use something else to edit your mpeg file cuz the ones in tmpgenc suck most of the times....
Hi!
I got to knoe the merging thing under this BBS and i tried it......
I have 2 NTSC MPEG file and i want to make it into 1 VCD ( they are of 30 minutes each ) the final output is in mpg. I use NERO BURNING ROM to burn the vcd out....
everything works fine.......
untilll.......
I could play the VCD on ALL VCD, BUTTTTTTTTTTT.......
for pionner DVD PLAYER, SMASUNG DVD PLAYER and PHILIPS DVD......
everything is veryyyyyyyyyyyyyyyyyyy choopy.....
Any suggestions?
** if someone knoes ( i m using final cut pro 3 on my mac ) can i export a MOV and encode it using TMPGENC to mpg?
I would guess that you burned the VCD at a speed higher than 4x. A lot of players will have problems reading VCD's burned at this speed as VCD's don't burn to good at high speed. Try reducing your burn speed to 4x.
