Hi. Can anyone pls tell me what's the difference between the NTSC (29.97fps) and the NTSC Film (23.976fps) that are listed on the settings???

I converted some avi movies to mpeg (with NTSC Film selected) and burned them onto vcd, but my vcd can only be played on some DVD players while can't be played on some?? Is there anything to do with the NTSC/-Film issue??

Thanks very much.

29.97 FpS is the native NTSC-Format.
23.98 FpS is for progressive Film, converted from Cinema.
While Playing the Player does a Field-Duplicating (3:2- oder 2:3-Pulldown) to get 29.97 FpS.

Considering that DiVX encoding under VirtualDub it's at least 3 times faster (with similar time consuming precise filter at max settings) .. and considering that MPEG4 encoding requires way more computation than MPEG1&2 do.. is there any chance to see a 250-300% performance improvement and some serious assembly SSE/SSE2 optimization for your algorithms ? Quality is high but if MPEG4 at max quality settings can be encoded 3 times faster then your code should be revised to give the same encoding speed, at least.

TMPEGenc is one of the fastest MPEG-1 encoders there is. It's a simple fact that encoding MPEG-1/MPEG-2 content is much more processor intensive than encoding MPEG-4 video. I'm not certain why, but my guess is that when encoding, an MPEG-4 file, the bitrate is probably about 600kbit, whereas when encoding an MPEG-2 file the bitrate is probably well over 2000. Even VCDs encode at 1150kbit.

Now, I'm sure TMPEGenc will get faster in the future as optimizations continue to be added, but for the moment, be content with the fact that it's as fast as it is... It's several times faster than Nero's MPEG-1 encoder or AVI2VCD's encoder.

Oh, and to speed up encoding you can mess with the motion search quality setting, it makes an enourmous difference. With the default setting, a 45 minute source takes about an hour on my machine to encode to VCD, but with the motion search on highest quality it takes 3-4 hours. Setting the motion search to the fastest setting may improve your encode times substantially at the cost of quality (more artifacts)

The bitrate has little to do with encoding time. And you're wrong, MPEG4 requires much more calculations than MPEG1 and MPEG2.

Hello,

Yes, I'm aware this is a TMPGEnc forum but many of you guys use VirtulDub and I have a unusual problem in VirtualDub

I wanted to cut clips from 2 seperate huge Avi's. I did the cut and saved at 'direct stream copy' video/audio for both clips. Then I tried to append them and got this error:

'Cannot append segment: The video streams have different sampling rates.

'file info' on the first avi was 9.997fps(100034 us)

'file info' on the second avi was 9.996fps(100045 us)

I re-cut the first clip at 'direct stream copy' and changed the framerate 9.996fps.

I still cannot append the clips.
The 'file info' on the re-cut clip is now9.996fps(100040 us)

Is the (100040us) and (100045us) difference the reason I cannot append?
How do I make them the same?

How do I make the first clip (100045us)? Because if the fist clip is 9.996fps(100040us) and the second clip is 9.996fps(100045 us) is won't append.

Thanks for any help VirtualDub users...

I have not seen that exact problem but why not try to "convert" the 2nd clip to the same rate. Yes I know that it is already at that rate but perhaps VDub will do to the 2nd clip what it did to the first and then they will both be the same. That should let you append them.

You are On the Wrong track here...the Message says that the 2 files have different Sampleing rates Not Frame rates..the sampling rate is the Frequency of the audio..I have gotten this Problem when trying to Append 2 files into 1 file and it is a Bitch to fix But you have to make a copy of the File useing "Direct stream Copy" for the Video and "Full Prosessing mode" for the audio and set the Sampling rate to the Proper sampleing rate and Make a copy of each file then join the 2 New files..

Hello,

Sndtek, you were right....it work. By simply setting the framerate to 9.996 an open the first avi/cut/save at direct stream copy and then opening the second avi with the same setting as above has made the framerates identical (both are 9.996fps(100040us).

Minion
The error was "The video streams have different sampling rates". Frequency of audio was the same (11025hz, 1Mono, 8-bit). So most likely it was the framerate that was the problem.
I have cut an pasted your post anyway because when that issue arrives, I won't have to grind my teeth...

sndek, Minion...thank you

Glad I could help!

Im usually use the Sharpen filter when i encode Mpg1 with the 352*288 Resolution
in the Sharpen Filter option there is a option to enable field base .When i use that option the Video gets even more sharp it seems...but are that option only intended to be used with mpg2 interlaced videos..how about Mpg1 352x288 ?
is it normal to use the field base option in mpg1 too ?

anyone ever use Field base option when using sharpen filter in tnmpgenc ?

Hi All,

OK. Here's the senario...

I use the Clip > Arrange > Center (custom) to plop a 640x272 avi (no black bars in source) onto a 480x480 frame. I enter the parameters to get what I want visually and naturally any area of the frame not covered by my avi show as black.

Now the question...

Does TMPGE encode the top and bottom black into the compressed video stream? Or does it only encode the active area and simply "tell" the player to blank-out the unused portions of the frame?

This is important (IMHO) because although a solid black field will compress to almost nothing, the transition from that black field to the active video will (I believe) take up valuable bandwidth.

Thanks

yes it does Encode the Black bars as Part of the image...

Thanks for the info.

Too bad you can't just encode the active video and let the player place it on the requested frame size on-the-fly. Kind of how a player reformats an anamorpic 16:9 for a 4:3 monitor. Actually, it would be an easier process for the player because it would not have to scale the video. Only add the blanking. Oh well...

Thanks again.

The the transition from the black bars to the picture doesn't take bandwidth if the picture has a size that is multiple of 8.

So if TMPG encodes the voids as part of the stream anyway, what are the pros/con between letting TMPG add the black verses giving it a aspect ratio corrected, full frame source which includes the black void (ie frameserving it from avisynth all ready to encode)?

I don"t think that it really makes a Differance But it would Be interesting to do a Test to see what encoded faster and which used the given bitrate more efficiently?...

If you're working on a 16:9 source, you may wish to make an anamorphic video.

Some TVs/DVD players are capable of taking a 4:3 image and scaling it down to 16:9 adding their own black bars. My TV is capable of doing this, and it increases the pixel density while doing it resulting in a sharper output image.

I had hoped that it was possible to only encoding the active playfield instead of the playfield + voids (albeit that the voids take up very little room). Making an anamorphic means the video has to be scaled vertically then reduced during playback. Thats 2 conversions away from the original source material, not to mention the larger file size and added encode time. A high price to pay for not putting the voids in the source from the get go.

The DVD video standard has 2 aspect ratios, 4:3 and 16:9. Black bars are NOT encoded except for very thin ones when 1.85:1 movies are encoded at 16:9 (1.78:1).

A DVD element (menu, video title, etc) with the 16:9 setting is assumed to be anamorphic and the player will squeeze the picture and add black bars (when instructed that the TV is 4:3). The squeeze is pretty sophisticated. Four lines are averaged together to get three.

This method allows 16:9 displays to retain full resolution.

When DVD authoring software sees mpeg input files with 16:9 flags in the header(s) it groups them together in a video title set that will have a 16:9 flag. Mpeg files that are not 4:3 or 16:9 will not be accepted by authoring software. Most consumer software does not accept 16:9.

IFOEdit can be used to change the aspect ratio setting for "video title sets" after a DVD has been authored. This allows you to supply anamorphic material encoded at 4:3 to consumer authoring software and fix the DVD database before burning.

What you say is correct. However, in my original post, the source material is 640 x 272. This translates to SVCD size of either 480 x 272 or 464 x 272 depending on how anal you want to be about pixel aspect ratios. I did not know if the MPEG-2 spec allowed the stream to be something less then 480 x 480 (or 720 x 480 for DVD) and simply place in the header information to the player that the video needs to be padded-out on the fly. If that were possible then 100% of the bitrate bandwidth could be for the active video.

To "take advantage" of amamorphic abilities of the player to vertically squeeze & pad-out with black would require that additional vertical detail be conjured up (ie vert scaling). That would increase the source material from 272 vertical to 400ish. Then the player takes that 400ish back down to 272 and plops it onto the output frame. Neither of these 2 conversions are lossless and the new vertically scaled source material is larger and would result in a larger encode.

I am trying to convert an avi to mpg but all I get is a blank, black screen (audio is OK). I have read others with the same type of problem and they've been recommended to increase the priority of the DirectShow plugin. When I do this however the whole program crashes! Any ideas? This avi is the second of two and the first one was fine.
Thanks

I doun understand why tmpg is going wrong. it is my first time using this software. I tried to convert avi to dvd file(mpg). And there was a error pop out ( scan line is out of range error:404).
P.S Plaze help!!!!

Can someone tell me why the exact same version of TMPEG can decoded AC3 on one computer and not on another? The only difference between the versions is that one is registered and the other if the free version. The free version is the one that works but they are the exact same version otherwise.

Dan P.

....and one computer has an ac3 codec installed and the other hasn't.

I have encoded hundreds of VCD's from avi files with this program before, but now lately, the program seems to be doing something very strange. I have a 349mb 44:00 video file, but when I try to convert it to VCD TMPGEnc says that the file is 142:00 minutes long and the program informs me that this is obviously going to be too large to fit on a CD.

Interestingly enough, I have a 140mb video file of the same length and it encodes perfectly...but I have been downloading more and more of these higher quality avi's and seem to keep running into this problem.

This file that is giving me problems is 512x384 24bit @ 23fps, and windows tells me the video compression is DIVXMPG4 V3. The audio is MP3 at 109kbs.

Any help you folks could give me would be much appreciated.

Well, guys, it looks like I fixed the problem...sort of....if I use the source range option and I set the end point just a few frames away from the very end of the file, suddenly TMPGEnc suddenly decides that I have a 44 minute video file instead of a 142 minute video file...is this a bug in the program of just something crazy going on with my crappy computer?

The Thing with Downloaded files is that they Get corrupted from being downloaded repeatedly so there are probably corrupted Frames or the header is corrupted and that is why it is giveing you this and other problems ,Downloaded movies aren"t the Best way to make High Quality VCD"s and Svcd"s out of..It is Best to Rip them yourself...

TMPGEnc seems to have problems with avi's that have VBR sound.. reencode it as cbr and itll be fine.

Jim

I am a newbie at this game, how/what program do you use you to do that ?

Hello, I'm having loads of trouble while trying to encode MPEG-2 with. I get loads of DLL errors, what i get is 'Write error occured at address 77F546F7 of module "ntdll.dll" with 00000000' and then run time error 216, please please please can someone help me ?
I'm using version 2.59 on a P3 700 running XP Professional.

Same problem here, narrowed it to XVID codec. Have WinXP with SP1, WinMediaPplayer9, tmpgenc .59. Can easily create from div3, xvid crashes... any help?

Yes the file i trying to encode is an XviD too :( Sometimes, very vgery rarely will it work fine, as i have done a few XviD encoding on .59, but none for a while because of this problem. I trying using ME, and 3 other computer with no joy :(

I read somewere that to properly encode Xvid files you have to change the Four CC code of the Codec to the Four CC Code of DivX...

I used TMPGEnc very often without problems but not I can't encode AVI files into mpeg anymore. Everytime I try to do it and i click to start the process a window opens saying that the file can't be opened or supported....It's quite strange because these files are normal DivX....can anyone give me a help please?

Have you raised the Priority of the "Direct Show File Reader"????

Where's that found? I'm having the same problem and I can't find any show
"Direct Show File Reader"...

I can't open any divx file with TMPGEnc, I could a few months ago when I last used it on an old version. I downloaded an old version and no go either.

hi i`m having problems with aiv and tryin to put it in mpeg and its sayin
cannot be opened or unsupported" i can watch it in windows media and its a avi file .but just wont let me put it into mpeg ..i hope anyone can help me and know what i`m on about ..do i need any over progs to do it
thank you all byr julie

Had this problem when I installed xvid codec removed it ok now

hey there,
I try to frame serve an AVI with VirDub using the Avery Lee subtitle plugin. When I start TMPG it says: error: divide by 0 !
What goes wrong?
