Converting 15fps AVI to VCD

[VCDjunkie]

Well, I have never had a problem converting AVI files to VCD until now.. I have 2 movies that are 15fps DivX 3, and with TMPGenc they have 1/2 inch horizontal bars across the screen, and with DVD2SVCD using AVI as input, the video looks great, but is moving at twice the speed of sound. When I tried to open the video in Virtual Dub and save avi, it crashed the program.

I think this problem is because the input files are 15fps.. not exactly your stanard PAL or NTSC format.

Any help would be greatly appreciated..

what template you loaded when you encoded with TMPGEnc. 15 fps type should load with NTSC 29.97 fps. Some divx encoded at 15fps (internally 30/29.97fps) just to make filesize smaller so if you load with NTSC template there should be no problems.

ya_jai,

I have tried every option in TMPGenc to no avail, including 29.97 fps NTSC.. I am not a newbie at creating VCD/SVCD, this is the first problem I have ever came across that I have not been able to fix myself.

Unless there is some other way to select NTSC template in TMPGenc that I am not aware of.. I am just selecting NTSC using the project wizard.. do you have another solution?

Also, does anybody know of a way to basically double the frame rate in order for the audio and video to be in synch when I mux the audio with the video to create the MPG? Like I said before, using DVD2SVCD, I was able to create a perfect looking video but it was too fast, about twice the speed of sound.. (is that mach 2 or something?)

With TMPGenc, the video and audio are in synch, however there are 1/2 inch horizontal lines across the whole picture, and the video looks skewed.

I can setup an FTP on my box and provide access to download the movie if you would like so you can see what I mean.. otherwise, to find out for yourselves, download from Kazaa one of these 2 movies..

Any help will be appreciated..

by the way, I changed version of TMPGenc, and it now allows me to change video options (before they were greyed out), however, there is another problem with these videos.. they are 318x238 resolution, which is not supported.

I am starting to think that this is not going to work..

[ya_jai]

It is really wried avi file. I downloaded the file you mention out of kazaa. I see why you have so many problems convert this one. I can encode it but the mpeg file come out half-left on the right and half-right on the left (I saw that half inch horizontal bar all over the screen as well). As you mentioned this file crash v-dub everytime I try to do anything with it.

I don't think this is the problem of 15fps though. I sucessfully converted 15fps and 12.5 fps before.

I will play with this file for a while and will give you a result if I can encode it or not.

Have you ever tried to change the framerate in the avi file using virtual dub first before converting with TMPEG????

[secretagent]

The problem could be with the audio portion. What I do is open the file in vdub go to audio set at full processing mode, then conversion and check 44100, stereo 16 bit and highquality. then in video i go to direct stream copy. then save this new file as an avi. then open the new file in tmpgenc
and encode away. usually solves my problem. if you check the audio it is usually 8 bit in the original file and this can cause the problem.

The answers to your questions:

yes, I tried using virtual dub, but it crashes when I try to preview or save avi.

I also have tried to encode using TMPGenc, and using video only.

The frame rate is apparantly not the problem, the problem is the resolution is 318x238.

This does not seem to be supported by TMPGenc..

I also have had the same results as ya_jai, after updating my version of TMPGenc, I also get the left and right side split after trying to do video only and changing resolution.

Thanks for the help so far guys!!

[secretagent]

if you have problems saving the avi simply frameserve it into tmpgenc with the audio settings i gave you. once again your problem IS the audio.

[reman]

the problem is the resolution is 318x238.

In TMPGEnc select Center Custom and enter 318x238 into the correct spots. That will allow you to have a 352x240 VCD with a picture size of 318x238. I use it all the time for strange sizes.

Good luck!

Reman,

using the custom option I still get problems trying to convert, usually get odd error messages like "invalid pointer operation", but when I do find a combination that does not produce errors, what I end up with is video split down the center.. right half of screen is actually the left, and vice-versa.

secretagent,

I knew that the audio was a problem also, which is why I chose to use TMPGenc to do video only prior to now.. I did go through the steps you provided using Virtual Dub, very good to know, but does not affect the final outcome using TMPGenc.. (split video down the center) even after producing the new .avi file, which is huge in size, almost 400mb.

CCE cannot even open the file since the frame rate is not supported.. no surprise.. also, Nero crashes when I try to drag the movie into it.. like we didn't see that one coming.

I did get the video to stop splitting itself down the center by making the resolution 320x320, 1:1 vga.. this creates a widescreen affect (top and bottom borders).

I am also testing DVD2SVCD to encode this using TMPGenc, encoding to MPEG1.. it said the frame rate was not supported, and that it would be adjusted.. The last time I tried this, it was using CCE, and since I had no luck using CCE by itself, I think TMPGenc may have more luck.

I will post my findings so that anybody who is interested can find out how this worked out.

I offer you to try and convert your video for you.

just give me a pm with your email and I´ll contact you.

Hope you have an FTP proggie to upload to my server

[VCDjunkie]

surferjoe,

you are more than welcome to try.. I think I will have a working MPG file when I get home from work today since I found out how, but since I am not home I also will not be able to upload the file.. Try downloading it from Kazaa..

yugioh_episode_36_-_yugi_vs_pegasus_(part_4).avi

yugioh_episode_37_-_yugi_vs_pegasus_(part_5).avi

Either of these 2 files will have the same problem.

Good Luck!

To anybody interested:

I was able to resolve the problem in the following way.

used TMPGenc to encode the video from .AVI to .MPG selecting 1:1 VGA 320x320.

used TMPGenc to mux the video with extracted audio.

used Sonic Foundry Vegas Video to crop and correct the resolution from 1:1 to 4:3, which got rid of the borders.

end result = perfect .mpeg

Thanks everybody who tried to help. I really do appreciate it a lot!

[VCDjunkie]

After further research because I had 2 movies to convert, it seems that the audio had much to do with the errors trying to convert in TMPGenc.

The second video I had would not extract the audio using vdub, it kept getting ACM errors, so I ended up using the "no audio" option for audio, and full stream copy for video, then saved the avi.

Then, using the extracted audio from the failed DVD2SVCD attempt, I then muxed my newly separated audio with my newly encoded .mpeg video .m1v file.. and voila, now I have my second video which needs to be ran through Sonic Foundry in order to crop/resize.

What a freakin nightmare..
