How does it work?
Encoding each field seperately, or de-interlacing it then encoding the progressive frame?

I have noticed a problem with encoding .avi(s) with TMPGEnc. Sometimes TMPGEnc thinks that an .avi is longer than it really is (for example, it thinks a 22 minute file is 44 minutes). I tried to set the end frame with the mpeg tools, but I was working on an .avi not an mpeg. After I made the mpeg, there was no sound, the file was the correct length, but there was no sound. How can I fix the problem of having TMPGEnc think a file is longer than it really is?

Thanks,
Dave

The Length Problem has Nothing to do with the No audio problem..The Problem with Tmpgenc reading the file as the wrong length can not really be fixed Because tmpgenc gets this information from the File itself, as Long as it comes out the Right length then there really isn"t a Problem..As for the Audio not being there you Probably should Extract the audio from your Source File to a WAV File with something like "Virtual Dub" or "AVI-Mux" and use the Wav file as the audio source..Tmpgenc will not encode all Audio formats...

It encodes it a field at a Time cuz the File plays a Field at a time and de-interlaceing the file doesn"t make the file Progressive it just blends the fields together as to minimise Interlace artifacts, depending on the Filter used...

So basicly, when I set the mode as interlace. TMpgEnc will encode 2 fields of a fram seperately. Then afterward, when it plays, the player put the two fields one after the other. Am I right?

Two more questions:

1.Is the set of field order important during the encode?

2. Does the other encoders like CCE deal with the interlaced video the same way as TMpgEnc?

Under "Source" do not set it to Interlace of Non-Interlace Because Tmpgenc will automaticly analize the File to check if it is Interlaced or Progressive and it will set it Accordingly, as For the Field order it is Very Important to have set correctly But Tmpgenc will set this also but only when loading the Source file in WiZard mode, so it is Best to Load the File in wizard mode to Find out the Correct Field order, CCE encodes Interlaced Files By Field also,..

Go to http://www.lukesvideo.com/ and click on "Interlacing", you can read plenty material over there...

How can I convert a 4:3 NTSC to 16:9 NTSC? I tried to recompile it in TMPGenc but it added black strips to the sides instead on top and bottom.

Do I need to change the size settings? They are set at 720x480 now.

Thanks

I have a Matrox Digisuite Max system which I use to capture video and audio. When I capture the audio, I get 2 files A1 and A2. However, TMPG Enc only allows 1 audio file to be encoded with the video file. This means I can't create stereo audio for my MPEG2 file. Help.

So you basicly just want to take 2 mono audio files and combine them to make one Sterio Audio file????You can do this with any Good audio editor Like "Sound Forge"...But you can load one of the Mono files into Tmpgenc and choose Sterio as the out put format and it will make a Sterio File with the same Mono file comeing out Both chanels, but that isn"t as Good as Combineing the 2 Mono chanels into one sterio channel..With a setup like you have you should have a Good audio editor...

Please don't post the same question twice.

I just did this the other day on a backup of Jaws. The source dvd is 4:3 and aspect ratio of 2.35:1. I'm not at a PC with tmpgenc installed so I'll be incorect on field names. Here is what I did. Under advanced set source to 4:3 NTSC keep aspect ratio. Under advanced clip, crop the top and bottom, about 96 lines each, I think. Check resized preview. If your source is 1.85:1, crop less. For output select 16:9 Display. I did not lose any of the image and it did not distort either. It was trial and error but it came out perfect.

Is your 4:3 source Fullscreen or Letter boxed?

If it's full screen then there is no point in converting to widescreen unless you are prepared to lose half of the image or severely distort it.

If it's letter boxed then set your input aspect ratio to 4:3, the 'video arrange method' to 'Fullscreen (keep aspect ratio)', crop out the black borders top and bottom and set your Output aspect ratio to 16:9.

I had converted an AVI file to a mpeg2(svcd).When I play it with media player,it is OK.But when I drag it forward or backwards,the player will die.And when I use the "merge @ cut" to cut the mpeg file,just as I type the time in the "Range" button,tmpgenc will die(no response for a very very long time).Why so?Help!
THX!

Firstly don"t use Media Player to Play Mpeg2 files, Use a Software DVD Player like "Power DVD", and to edit mpeg2 files in Tmpgenc you have to have the correct Mpeg2 decoders installed so Tmpgenc can decode the File so you can see it in the Editing window, installing Power DVD Will install the Proper Decoder, and Tmpgenc"s Merge & Cut Isn"t very Reliable for editing ,it would be better to use a Real Mpeg editor....

Thanks minion you da man, you solved my dvd screeners problem! FYI this is what I did. I went to http://www.doom9.org/ and downloaded a program from the Filters section called ffdshow. Soon as it finished I had access to all my xvid screeners. These screeners I refer too are all from dvds but aren't released yet, like "Gangs of New York" and without this ffdshow, I couldn't play them or make vcds. Now I can. The doom9 site I gave the address to actually has many other downloads everyone here might be interested in seeing(in case you haven't been there already.

ok, so every one keeps telling me there's no way to play my dvixs on my apex dvd player. I Was think this could convert it for me, but it wouldn't work, well the video wouldn't. So if this program will do it, please help. If not and you know of one that will, that would be cool too. Thanks

See my post just after (before in time) yours on this page. Both of my DVD players are APEX (one is branded GE, but according to some of the firmware hacking sites, it contains the Apex 703 guts), the other is an Apex 1010w (Wal-Mart had these for under $50 just before xmas), according to the Playback compatibility I found at Doom9 and dvdrhelp.com, you have to have a more recent serial number on the ad-1010w for it to be able to play VCD's. Luckily mine was compatible with VCD formats; I haven't tested SVCD formats yet. As I stated in my earlier message, I have no problem burning most mpegs that I already have as VCD's, but the ones I convert from AVI, would freeze on the 1010, and the 703 would speed-up and slow down messing with audio sync in spots.

My testing has basically confirmed what Minion told me, TMPEGEnc tends to allow bitrate bursts into the final file. I played with my settings by selecting a small segment of the AVI around where I saw the problems occurring and just played with the settings. I would burn to CD-RW so I wouldn't waste a bunch of CD-R's. I did not have any luck until, by chance, I decided to try encoding at a lower bitrate so that I could fit an entire movie on one VCD. In this case, the movie was 94 minutes long, so I used an average bitrate of 980kbps on the video. I found that Nero and my Apex players seem to be happy with VBR files (as long as the bit rate remains under some yet to be determined max value, 1150 makes sense, since CBR of 1150 has the most problems when using TMPEGEnc). I encoded a test using VBR avg 980, max 1200, and min 800, with very few problems in the resulting file. The GE player still seems to show a bit of speed-up slow down sync problems with that test, but the 1010w played fine. If you are happy with the VBR or lowered CBR results, this is safe for personal use on players you can characterize, but it leaves the standards behind, so it is definitely not good for distribution.

For best results, I have found it best to use VirtualDub to extract the audio to a wav file. Do any AC3 down-mixing or mp2 bitrate conversions using external tools, you can allow TMPGEnc to do the audio processing as long as the DirectShow priorities are raised in the environment settings, but the combined processing seems to aggravate some audio sync problems with some files. It is better to do separate elementary streams and combine them using the multiplex option in TMPGEnc's MPEG Tools dialog. Also I have seen several reports that it is better to encode the whole video (assuming you remain under file size limits of windows), and then use the merge - Cut tools to split across multiple VCD's instead of the source range filters during encoding.

Here is a guide that I found on the lower bitrate to fit on one VCD:

Since you already have the AVI's you can skip past the first few steps.

They have a lot of useful info.

I'm still playing with other encoders to achieve fully compliant VCD's.

This is a strange problem: (apparently common based on posts in other forums)

When I use TMPGEnc to convert an AVI file to MPEG1 for authoring of standards compliant VCD, the resulting file plays fine in Windows Media player, but when burned to CD-R/CD-RW and played in standalone DVD players, the video freezes in spots on one, and another looks like it is speeding up and slowing back down until audio sync is restored at or near the same spots in the video.

After turning on TMPGEnc's log file output, I have found that the areas where the problems occur seem to be where the video motion is low thus the mpeg encoding doesn't need as many bits. Tried 2-pass VBR, MAX 1150, AVG 1150, Min 1150 with same result as standard CBR 1150, same video problems.

I have used VirtualDub to check for bad frames, there are none. I have played with VBV buffer size settings, Interlaced frame order (even though my source is de-interlaced), frame rate conversions, and GOP sequence.

The only thing that seemed to improve the playback on the standalone DVD players was to decrease the video bitrate (2-pass VBR, max 1200, avg 980, min 800). However, I have several standard VCD compliant MPEG1 files that play fine on these DVD players when burned to a VCD CD-R. These MPEG1 files were captured using a hardware mpeg1 encoder like the ATI All-In-Wonder card.

Using tools to dump the Mpeg files, the only difference that I have found thus far appears that TMPGEnc includes a substitute quantize-matrix, and a user data area. a few of the other fields contain diffrent values (look like defaults; 65535), but i'm not familiar enough with their meanings to know what matters or not.

As a test, I downloaded a demo for a product called EO Video, and did a test encoding. That also plays on my DVD players, but EO does not have the configurability or quality that TMPGenc does.

Any suggestions as to what I'm doing wrong would be appreciated. I have tried so many variations, that I have worn out a few of my CD-RW's.

First Off the "All In Wonder Card" is NOT and Hardware Mpeg Encoder, it is not a Encoder at all Just a Capture device, it is the Software (MMC 7.*) that you are captureing with that Is Encodeing the Signal from the All in Wonder to Mpeg, so at best it is a Software encoder...And the Problem with the Scips and Jumps and Video slow down and speed back up are Caused By "Bitrate Spikes"..Tmpgenc does not Have very Good Bitrate controll, it takes your Bitrate setting as More of a Sugestion..So the Problem is that the Bitrate is Going Much higher than you set it, this is one of the reasons why I don"t use Tmpgenc Much anymore..All you can do is either Lower the Bitrate or Use a Encoder that has Better Bitrate controll, a Good One for Mpeg1/VCD is the "MainConcept Encoder" and it is much faster than Tmpgenc...

Thanks Minion, I will try the other encoder. For the working Mpegs, I have no idea how they were captured, the ATI card was a guess on my part. I got the hardware encoder statements from what I though I read when looking at one of their cards in the past. Might have been mpeg2 decoder for DVD playback on another card now that I think about it.

Hi,
I encode to mpeg2 from a m2v-file with 2 pass vbr (and 720x576 pal, 16:9). I keep receiving a giant logfile with entries for pass 1 that seem ok and all entries for pass 2 that look like this: frame= 89878 [I] estimated compressed size= 98272 compressed size= 89248 overflow= -9074. The resulting m2v-file only contains like half of the movie.
Any idea to this?

What is your VBV buffer size setting?

I tried it with 224 and 0 (automatic), results are the same, starting pass 2 results in overflow entries in the log. ???

Actually there is one entry per frame in the log, average frame count is like 90.000 frames per movie. Funny enough that the movie runs ok for about 1 hr and then terminates.
