I have a feeling that there is a standard and annoying excuse for not havin this. The excuses usually range from, 'no one uses it' to 'jpeg is good enough.' Well it isn't inho. Image quality is important, more so if you start with something that might contain minor and barely noticable flaws, which jpeg 'may' in some cases amplify. If you are producing the images for something to be shown on a TV or the like, where the quality of what is shown tend to hide many flaws, then this is not a major problem. However, a lot of stuff produced is now made to be shown on computers, where flaws won't be hidden. If shifts or other glitches exist in the original pre-stream images, then there is not much you can do to remove them during compression without farther degrading the image.
The obvious answer for most people is likely to immediately be, 'well then just use BMP or something'. Great idea, as long as you are already being paid for your work and have a lot of space to store the images. If you are limited on space and don't have the kind of income that allows you to upgrade your system every time the project you want to do (especially as a hobby) grows beyond what the hard drive can store, then you can't 'just use BMP'. PNG provides a decent solution to this issue, providing a no-quality loss image, but compressed enough to be useful.
It frankly bugs me that it is not supported in things where its use can be a significant benifit.
Well I'll just throw in my few cents worth just to annoy you.
My simple answer is that TMPG is in actual fact an encoder designed for MPEG encoding, the other formats it can handle are just a bonus. So if you need the feature that you ask for find a program that is designed for it.
> TMPG is in actual fact an encoder designed for MPEG encoding
??? What the heck does this have to do with anything? Of course it is an MPEG encoder, but you have to encode the stream from some other source. I see neither a practical reason nor a logical one to limit those sources to file types that are at best inconvenient, at worse degrade the image, or even worse, are something like AVI, which may just add its own complications to the mix. I'm sorry, but I never saw the logic in having to use 3-4 different programs just to convert something into a format that a program like this one can actually encode. This is just plain stupid imho.
Yes, being able to encode from a list of files might be a 'bonus', but if so, that doesn't leave a whole hell of a lot of file types it can encode from without that bonus. Why is supporting a decent format that saves the user some storage space any less reasonable a thing for a program like this to have?
I swear, half the time, trying to do anything with video or 3D graphics is like a bloody digital version of a Rube Goldberg machine. Why do something in one simple step if you can do it in six steps, take ten times as long and use twenty times the disk space to do it? You can't tell me this actually makes any practical sence to you. lol
The problem here is that in your eagerness to have a rant you didn't quite clarify your problem.
It seemed to me you were seeking to encode to this PNG format not use it as a source which is why I made the comment about TMPG being an MPEG encoder.
If all you need to do is import this format into TMPG as a source then that is simple. Use AVIsynth or Virtualdubmod to frame serve the clips to TMPG.
It maybe an extra step, but it's only one and it only takes a moment to set up.
Sorry. This is sort of a sore point with me. lol Seems like everything I ever buy or download has some statement in it that says, 'but if you want to do this, you will need program x, y and z.' This gets quite annoying and I ran into the problem several times this last week, which got on my nerves. ;) lol
Your suggestion does look to be a decent solution, if slightly annoying, since it won't work in a direct fashion. I still would prefer in the long run seeing it as a real option, but for now I guess learning yet another script system will have to do. lol
Avisynth is not really that hard to learn once you get the hang of it and it does work with the files you wish to import. If you do any sort of serious video work then you will find AVIsynth invaluable.
The only thing is that it seems to flip the picture upside down with these files, so you would have to use the FLIPVERTICAL command to correct this.
If you don't want to bother with scripts then Virtualdubmod is the best solution.
Yeah. I code in POV-Ray SDL script, VBScript, some JavaScript and recently dabbled in Python. Unfortunately it seems that AVISynth has the same problem the mud client I use had for close to a year or more, the docs that are local to the users machine are out of date and don't even show the ImageReader command. Had to look at the online docs to find it...
The irony here is that 24 hours after your suggesting someone pointed me to this:
It includes a plugin file (guess you would called it beta) for TMPGEnc that reads PNG directly. Its nice to find out that having fallen out of a plane that you got lucky and hit a matress factory, but slightly less helpful when you hit it several days before they actually start building it. lol Dues Ex Machina isn't much help if it happens after you originally needed it. ;)
Hmm.. You can tell I have been re-reading Terry Pratchett's Discworld series the last few days...
Video Stream: Motion Video, 320x240, 29.97003fps (NTSC), 1024kbps
Audio Stream: Audio Standard MPEG layer2 Stereo, 32KHz, 327680bps
I would like to make VCD or SVCD with them.
My TV is PAL and my DVD player can play both VCD and SVCD.
A CAT HTC 2002 but in SVCD the menue is crupted but video files play OK.
Since my original files are only 320x240 is the any point in making them SVCD? As this needs twice as much time to render as VCD.
Which imput aspect should I set, 4:3 or 4:3 NTSC or some other?
Any pointers as how best to produce SVCD / VCD would be most helpfull.
when I trie to encode from an avi to mpeg ik keep getting this violation error:
Write error occured at address 77F73AED of module 'ntdll.dll' with 00000000
This error usually happens with XviD files, what usually works is to delete the XviD codec and install the FFDShow Decoder and configure it to decode XviD files then the error shouldn"t pop up...

Are these files not already VCD?
It seems to me you already have an MPEG. If that is the case and your DVD player can handle NTSC then all you need to do is add a VCD header to the MPEG by running it through the simple multiplexer, set the stream type to 'MPEG1 VCD' then just burn as a VCD.
Note: you will most likely need a multi standard TV to play NTSC sources on you player. Most modern TV's are.
If it can't handle NTSC then you will have to convert to PAL VCD, but unfortunately this is tricky to do properly. So post back if you need further assistance.
And 320+240 isn"t Quite VCD Resolution But it Might play but it would be a non-Standard VCD, If it doesn"t then you Might have to encode it to the Proper VCD resolution...unless 320+240 was a Typo...
You Might need More ram...And if your PC is Only 500mhz it is Goung to take a Long time to encode as 500mhz is really slow, You can Probably upgrade to a 2ghz for about $100...
How much RAM do you have?
I still think this is a virtual memory issue.
Which operating system are you using and are you letting Windows manage your swap file?
Have you tampered with TMPG's default Temp and folder settings?
I have 128 MB RAM and set the virtual memory to 256.
I use Windows 98 SE.
And I also changed the TMPGEnc-temp-path. The temp-file is saved now on the drive with the most space.
Should I transfer the swap file to my video drive, too??
Firstly your virtual memory setting is far too low for video work when you only have 128mb of RAM. To be honest with the limited amount of RAM you have, which is very low for video work, you should let windows manage your swapfile. This way it will dynamically expand as more size is required.
Also it is usually not a good idea to mess with TMPG's Temp settings as this commonly causes problems, leave it at default.
How much avaulable space do you have on your default drive?
It always advisable to have your swapfile on a seperate drive from the operating system providing this drive is just as fast as the default drive.
>Everybody says that you should set the swap file to a fixed size when you do video work. You are the first who don't agree...
Maybe, but you don't have enough RAM for video work as I said nor is your swap file large enough. 3.5x your RAM at least is recommended for the swap file setting.
No, I don't think I had to less RAM for video work. I do video work since four years with "only" 128 RAM.
MPEG encoding was the only thing I had trouble with.
I just tried to encode an AVI (NTSC 23.976 fps) to SVCD (NTSC).
I did this a 1000nd times and mostly the result was satisfying.
I always used the 3:2 Pulldown Flag that tells the DVD-Player to add the required frames making a 29.97 NTSC output.
I now came across some AVI file (NTSC 23.976 fps) where everything seemed to work fine as usual but there are parts in the movie which are extremely jerky.
Could it be that the AVI is not entirely runing at NTSC 23.976 fps meaning there are parts within the VAI that have a diffrent framerate?
How would I find out?
In general what is the better approach setting the flag or let TMPGENC do the job and add the frames?
What I would do is Encode it as a 23.97fps file then use a Little Program called "Pulldown.exe" or "DoPulldown" to add the Pulldown Flags..And Make sure that Tmpgenc see"s the File as a Progressive source cuz who ever made the File could have done something stupid Like taken a Fully NTSC Source and encoded it as 23.97fps Interlaced, in which case Pulldown would not work properly..I have downloaded a Few Files that were like this...good luck...Cheers
You can use TMPGENC's mpg tools for splitting.
But that is a lenghty process and produces sometimes strange results.
I recommend to split the files before you encode or use the source range feature in TMPGENC.
Audio mutes at the end of the file and video goes on for another 10 seconds
'Odd' algorithm splitting an already intact mpeg file through demultiplexing and then multiplexing again.
Takes forever .....
>Audio mutes at the end of the file and video goes on for another 10 seconds
Well this must be unique to your file. There are others who have problems with the MPEGtools and this is usually due to dodgy MPEGs and dodgy systems..
TMPG's own files hardly ever cause a problem and I have to say in the years I have been using TMPG I hardly ever have had a problem splitting most MPEGs except for ones created with other programs which when checked are usually corrupt in some way.
It also can be caused by a badly configured system. People don't realise the effect of installing every codec known to man (namely these pathetic codec packs) and other conflicting programs can cause.
TMPG relies on directshow for splitting MPEGs and therefore any problems with directshow on a badly configured system is only going to manifest itself like this.
My system is clean, I only have the codecs I need and the MPEGs I create are not corrupt in anyway hence hardly any problems with TMPG.
If it was purely a TMPG problem then it would happen to everyone, but it doesn't.
Well there could be an error in your AVI file at the Point were it is crashing, especially if it is a file you downloaded off the net as they are easilly corrupted, you can try to use the "Source Range" to start encodeing again a few frames after were it crashes then join the 2 files together with the "Merge & Cut" But if it is only the Credits you are Missing then you might just take it as it is as No one likes Credits....
I convert my AVIs to MPG in order to see them in VCD PAL format non standard (XCD I´d daresay). I use 2pass-VBR or CBR indistinctly, using the wizard to get the best control of BR<->MB in the final table. Then burn mi MPG file in Nero.
The results are fine when I use 80Min CDROMs. But when I burn a 90Min CDROM (to get more cuality in large films), and view the results in the DVD player, at the end of the film there are a lot of moments with freezed images (without sound) that last from some instant to 2-3 seconds. That happens whatever the DVD player I use (all of them with a great VCD-SVCD standard and not standard compatibility).
Why?
I blame it on the 90min CDs. They're not quite standard and therefore the DVD-Player has problems reading them always a 100%!
I found a workaround and that is burning them at a resonable speed (8-12).
Yes I would Blame it on the Disks or your DVD Players lack of ability to Play over standard sized disks, and you should ALLWAYS Burn (S)VCD"s at a Low speed, usually about 4 or 8 speed Max as (S)VCD"s have no error correction so Burning at high spped will cause a Lot of errors to occur...
MPEGs should not be burned at high speed and that means any higher than 6x.
4x is the ideal speed for MPEGs and is the most compatible speed. 8x may work fine on one player, but take it from me it won't work on all I have learned this through experience.
>I had this problem predominately with NERO!
In my experience and the tests I have done it doesn't make a difference what burning software you use.
It is the burner you use, the disks and the speed you burn which are the main factors.
Hello, when i am outputting the dvd it always freezes at 68%, no idea why and no error messages, the input video is taken from a captured mpg file
MPEG-2, 352x240 29.97 fps (4:3), bitrate 4998 kbps
i am useing an ATI All in wonder card to capture
I've a AVI which I want to convert to mpg before burning it to a SVCD. The problem I have is, it displays:
"WARNING: NOTHING TO OUTPUT BFRAME DECODER LAG"
when I try to load it as video source with TMPGEnc.
This sound like it may be a codec problem to me.
Download and install FFDSHOW.
If your AVI is XVID then make sure FFDSHOW is configured to decode XVID files by ticking the relevant option.
I see a way to fade in the audio at the beginning and fade it out at the end but what I really need is to fade bioth the audio and the video in and out. Is this possible?
