Part2.....Continued from a previous post


Step 4.

The next step is to sync the Audio.
open Cool edit 2000.

When the program opens you will be presented with a box allowing you to choose 2 options. Choose options 1 and 3.

In the program click file>open and open the wav you created earlier.
Wait for it to finish then click 'Edit' and untick 'enable undo' then click 'select entire wave' next click 'Transform' and choose 'Time/pitch' from the drop down menu then click 'stretch'
In this box tick the following options:

Low precision
Time stretch (preserves pitch)

In the box that says 'Length' type in the exact figure you got in secs from Virtualdub for e.g. 4802.360 then click ok.
Wait for the program to do it's stuff then when its finished click 'file' then 'save as' and name and save your file as a wav.

This should give you a Wav file which will be the same length as the movie in the next step. Close Cool edit 2000.Step 5.


Next go into your Virtualdub folder and double click the file called AuxSetup.exe and in the box that pops up click the button which says 'Install handler' and click 'OK' to all the other boxes that come up then click 'Exit and restart your system.

Step 6. This is where we change the frame rate of the movie.

To change the frame rate of an AVi all you have do is use a little program called 'AVI frame rate changer' Just open up the AVI with the program and change the frame rate.

To check that the movie is in sync with the audio, open up virtualdub and open your movie then click Audio and choose 'Wav audio' from the menu and find the wav you just created.
Click the first play button and you should find the audio is in sync with the movie.

Open up virtualdub and open the MPEG you created from the SECOND or THIRD method. Click Video and choose 'framerate' from the menu and change your framerate to the one you want to convert to. e.g. 25fps

To check that the movie is in sync with the audio, click Audio and choose 'Wav audio' from the menu and find the wav you just created.
Click the first play button and you should find the audio is in sync with the movie.
Next click 'Audio' and choose 'No audio' from the menu.

Now click File and from the menu choose 'Start frameserver'. A box will appear with the name of your file, click start and in the next box give the file a name and an .AVI extension then save it with where you want. This will start the Frame server. DO NOT CLOSE THIS DOWN.


Now use the AVI you have created from either the one you have changed the framerate of, using 'Framerate changer' or the one you just created with the Frame server, as your Video source for TMPG and the wav file as your audio source for TMPG.
Choose your VCD template PAL 25fps or NTSc 29.97fps and encode as normal.

If you have problems opening the AVI in TMPGenc which you have created then go into the Virtualdub folder. There should be a folder called 'AVIPROXY'. Open this and double click the 'proxyon.reg' file. You may have to restart your PC after this. After you have finished encoding click the 'Proxyoff.reg' file.

Phew....

I tried to make it as clear as I could even though it seems a little complicated, but it's really quite simple.

NOTE: Even though this method will stop the jerky playback and sync your movie, depending on whether you increase or decrease the framerate, the Movie will play slightly faster or slower.

This is normal and hardly noticable.

Let me know how you get on 'cos this took me ages to do.

Part1

*** This post is people having problems when converting Movies from one framerate to another e.g
29.97fps to 25fps which is causing the resulting movie to have jerky playback. ***


Instructions:

First we are going to need some software.

1. Virtualdub: http://prdownloads.sourceforge.net/virtualdub/VirtualDub-1_4_9.zip

2. Cooledit 2000: ftp://207.109.248.242/disks/cooledit/ce2kmain.exe

3. Aviframerate changer: http://www.divx-digest.tv/software/edit/avifrate101.zip



Step 1.

The first step is to install all the above software then the next thing is to start with your original AVI if you have one. If not then we are going to have to use either the MPEG file we want to convert that doesn't jerk or the MPEG file that we have already converted that does jerk.

I will outline all three methods below.

Step2.

First method:

**Starting off with a jerky MPEG which has already been converted.**

What we need to do is convert this MPEG back to it's original framerate to remove the choppy playback using TMPGenc.
Load one of the VCD templates either PAL or NTSC depending on your T.V. system.

Now click load again and this time choose the template which says Unlock.mcf
Load your MPEG and under 'Stream type' click Video only.
Click setting and under the Video tab change the framerate to what the original movie was. So if the movie you have encoded is 23.976fps and the original was 25fps then change the framerate to 25fps. Leave the size as it is, it should be the same as the source. Under rate control choose CBR at 4000kbps. (The reason for this is to preserve quality so make sure you have plenty of hard drive space).

Under the advanced tab choose the 'Source aspect ratio' either 4:3 625 line PAL or 4:3 525 line NTSC depending on you source movie.
Choose your output and we are ready to encode.
When TMPGenc has finished check the movie to ensure it plays smoothly again. If it's ok it then Goto STEP 3.

Second Method:
** Starting with an MPEG movie which doesn't have choppy playback **
Goto STEP 3.

Third method:
** Starting off with an AVI **
Goto Step 3

STEP 3.
Once we have our MPEG or AVI which doesn't jerk then we can begin to change the framerate of the movie.

Start up Virtualdub, click File and open your MPEG or AVI you created from the SECOND or THIRD method. In Virtualdub click File then click 'Save wav' and choose where you want to save then click save.

Next click Video and choose 'Frame Rate' and change the frame rate to the one you want to convert to i.e 25fps.
Now click 'Edit' and click 'end' from the menu.
Note what it says in the timescale box as the length of the movie exactly.
Now calculate what the total time is in seconds. For example 1:20:02.360 would be 4802.360 secs, write this down. Close virtualdub.

The Next part is continued in another post as this post was so long it wouldn't allow it.

Continued..........

The address of the third software doesn't exist.

3. Aviframerate changer: http://www.divx-digest.tv/software/edit/avifrate101.zip

Try it again buddy. It works fine.

Hey Ashy,

Don't want to sound like a suck-up, but i think you're brilliant. This solution works just fine. This solves a problem wich saves me many, many ours behind "the screen". I realy don't think that i've could handle this problem at my own. Really, thanx..!!!!

Now i can finally watch my favorite movies on the dvd-player in stead of the computer screen.

I've passed your solution to a lot of my friends, who had the same problem, so alot of thanx from the netherlands.....

Greetzzz,

Dennis

btw, the links are working just fine indeed.....

Glad it helped you dennis.

ASHY

This is a little off-topic, but could anyone tell me what other programs are out there to convert MPEG2 to MPEG1. I like TMPGEnc, but am curious what other options there are. Thank you.

There is none really out there as good a TMPGENC.

Techno

I agree that TMPGEnc is very good (and am very happy with the quality), but if I were looking for another program, what others are out there. Thanks.

FlaskMPEG is another option but is one hell of alot slower (50 to 60 hours encoding time for a DVD Movie) and generally doesn't produce the same high quality, apparently it can be useful if you wan't to include subtitles from a DVD.

Can anybody tell me that
where can i find the source code for Mpeg1 decoder and play???
thanks a lot.
I need this source code to finish my job
thanks a lot

best regards

YOU CANNOT get this source code!!!! (as far as I am aware off)

Techno

I do not think there is such thing.

I keep getting (mpg cannot be created?) I have no clue why?

>I keep getting (mpg cannot be created?) I have no clue why? i've converted the file before but then formatted my system and got the original file mpg style and downloaded the same version tmpegenc. newest but this time it won't let me do it? everything is exactly the same as last time but it just keeps saying "mpg cannot be created"

>>I keep getting (mpg cannot be created?)

I was creating vcds did the load tab and settings bit..

Hi,
Does anyone know of a way how to limited the amont of frames encoded in TMPGenc. I have an input m2v filebut i only want to encode the first 350 frames of the sequence. how can I do this?
Joey

In the settings, goto the advanced tab, then click on source range. Select the frames you want and hit ok then encode!

Techno

Joesph -

I was interested to see you experiment with VBR vs. CBR. I was wondering how you tested the resulting files. Here's my problem... I need to encode several old tapes of various qualities from VHS, SVHS, Std.-8, Hi-8, etc. I'd like to get as many minutes as possible on the DVD's (different DVD's for different sources). I would imagine that, to do a Hi-8 source tape justice I would need a higher bitrate, than say using a VHS source tape. Any idea how I can go about determining the minimum bitrate for each source without significantly sacrificing quality. Yes, I could just good just use a CBR of 8Mb/s for everything, but that would be very wasteful, especially for low quality source tapes. Do you know if there is any way to get TMPGEnc to scan a portion of an AVI file and recommend the optimum bitrate? Ideally I'd know how much I can get on a DVD before commiting the encode and burn time.

Thanks,

- Ron

when i used to encode movies in the past, i always checked to see if they encoded right and they were in NTSC form before i would start burning them. Now i am doing the exact same thing but mu burner does not recognize the file as NTSC. I have tried using nero and ez cd creator roxio and they both can't recognize it. I think i'm doing everything right because i have done it in the past. I did load the template everytime. I'm not getting any error messages but when i go to play it in my dvd player it does nothing.
i hope someone has some ideas because i'm stuck
thanx

Have you tried downloading a NEW NTSC template from another site? (www.vcdhelp.com) Ur template maybe corrupted.

Techno

ok i tried a couple templates but none seem to work

I have downlaoded TMPGEEnc 2.53 and am having trouble converting about a 60 MB .avi to a new .mpeg file. I got a 1.8 ghz, 512 SDRAM, no problem with the system. When i convert, the program seems like it did everything correctly. I try to play it on WinDVD 3.1, but all that happens is that the screen is solid black, and i hear the audio. I have tried converting to SVCD and just VCD, using differnt bitrates (650,800,1000). I have nimo 4.4 codecs, DIVx5, and the newest updates on WinMedia player. One other thing, i got this program because nero 5.5.6's mpeg2 add-on couldn't burn this to SVCD properly either. I burned that same file (the program auto-converts before burning), along with a 20 MB mpeg. The same thinghappened with the .avi, but when i skipped to the next file (mpeg) it played fine. Any suggestions? If you need anymore info to help me, just mail me and i'll tell you. Thanx.

Hi,

seems TMPGEnc does not work with DivX5 !! Downgrade to DivX4.12 and you should have video and audio again.

Holger

Yeh, DIVX 4 and 5 sux but this is the only way to convert it properly.

Techno

Hi,
Does anyone know where I can get version 2.02 from?
Joey

just search for it on the web.

Techno

I downloaded the program. I set it to start and I get this message: "Can't load "P3Package.dll". Someone has any idea of what it means ? Thanks.

the p3p package optimizes the program for pentium 3,try re-downloading the program and see if that works,but if it doesn"t here is how to make it work,under the "enviromental settings" go to the "cpu" tab and un-check everything,this should work but it might take longer to encode.....sherlock

Hi Todd,

ReelDVD doesn't support MPEG Elementary streams with Layer-II audio. You must create separate video and audio streams. Then ReelDVD will accept your files.

To create ReelDVD-compatible widescreen MPEG with TMPG you should try:

Output Stream to Video Only (remember, no Elementary streams for ReelDVD)
Stream type MPEG-2 Video
Size 720 x 480
Aspect ratio 4:3 Display
Video format NTSC
Encode mode non-interlaced (if appropriate)

Here's the important part: GOP structure

For best quality try:

Number of "I" pictures in GOP = 1
Number of "P" pictures in GOP = 0
Number of "B" pictures in GOP = 0
Output interval of sequence header = 1
Max number of frames in GOP = 1
Output bitstream for edit (Closed GOP) = checked

The first 3 items can be altered, but not the last 3.

'Hope that helps,

I'm stumped on this. I am using DivX 5.0, the audio codecs of Nimo 4.4, and the latest TMPGe and Virtual Dub releases...

So Here's the problem: every single AVI to MPEG1 conversion I do in TMPGe is coming out full-screened. This has only started happening recently.The DivX files will playback in "letterbox" mode in WMP, yet the MPEG1/VCDs I make in TMPGe come out strectched and full-screened to the max, and it never used to do this! I am currently using DivX 5.0, the audio codecs of Nimo 4.4, and the latest TMPGe and Virtual Dub releases...

I have tried changing the aspect ratio and the video arrange method option in TMPGe, and it is still full-screening every MPEG1 video I try and make. The video and audio quality is good. Have also tried un-installing DivX 5 and going back to 3.11, and it is still full-screening every file.

It is doing this on every single file - please help! thanks.

I use thist trick: load VideoCD, then load the unlock file. Now you have Letterbox.

I downloaded the program. I set it to start and I get this message: "Can't load "P3Package.dll". Someone has any idea of what it means ? Thanks.

i went into the options menu in TMPGEnc and I unchecked everything under the CPU column from the environmental settings and that worked for me. good luck
