divx to dvd, is it possible??....please......!

[Mauserman]

Hi!!

I have this divx movie that i want to author as a dvd, i chose the dvd preset in ffmpegx an hit encode, but the result was about 5 seconds out of sync. I guess i made a misstake somewhere but i really don't know what to do now.

Does anybody feel encouraged to help me with this i would be most greatfull. A walkthrough on this task would be very nice.

(and i did search the forum on this topic, but it didn't help me).

It sounds like you may be encoding at the wrong frame rate? I would mess around with either 24 or 29.97 (if it is an NTSC source). Check and see what frame rate your divx file is in.

How can i check the frame rate on my divx movie?

And thanx for your answer.

[Mauserman]

I have checked the movie in quicktime, and the movie frame rate is 29.97, wich i think would make it ntsc. Since i went with the ntsc dvd high quality preset in ffmpegx, i chosed the right format i think.

My guess is that something is happening with the audio when it's converted to another bitrate. As a divx movie the sound was 44.1 khz and the dvd sound is about 48 khz i think?

Am i right about this?
If so, how can i correct this problem?

Is "Set 3:2" also disabled?

[Mauserman]

Is "Set 3:2" also disabled?

Well i have'nt unchecked anything, i just went with the preset for dvd. Should i run again with "Set 3:2" also disabled??

[major]

If the source DivX is NTSC then you should not set 3:2 which is meant for NTSC FILM material.

[Mauserman]

ok!

i will uncheck it and try again.

thanx!!

this usually works, extract and convert the audio to wav using GOLDWAV, and then use TMPGEnc to encode the file. put the original avi and then the WAV as audio, and it should be fixed.

[Mauserman]

I finally solved it, but probably not the quickest way.

I opened the divx in quicktime, and exported the sound and movie as separate files. Then i changed the audio to 48khz.

Then i added the movie to the sound (Add Scaled), then i ran the reslulting .mov file through ffmpegx again and the audio was now in perfect sync.

Thanks for all the help guys.

Mauserman, I also have divx files I would like on DVD, could you please contact me or anyone who knows how to do this. I read through the post but i don't really understand it. Please Help. My email address is toym1@tampabay.rr.com

When reencoding from DIVX to something else, I almost always first run the DIVX file thru Divx Doctor, which creates an .MOV file (with uncompressed audio). I don't experience audio synch problems after that. Look for the program on Versiontracker.com of at 3vix.com:

Another tip... When you select "NTSC," you get NTSC Film (whatever that means), which is 23.976 fps. In the drop-down list, there's another choice for NTSC, which is 29.97 fps. I'm still experimenting to determine when to choose which fps, but you might try changing this to one that matches your original file.

I'm having trouble matching the video with the audio, and I'm pretty sure it has something to do with the framerate. In quicktime, it says my divx file FPS is 12.5, whatever that means. I encoded it using the NTSC Film framerate option and the video came out to fast for the audio, then I did if as PAL and it came out perfect, but that does no good because I can't watch it on my tv. What am I doing wrong?

[gmackenz]

In quicktime, it says my divx file FPS is 12.5, whatever that means.

Duuuuude. No way can that be correct. It is either NTSC (~29), NTSC film (~23), or PAL (25). Open the file with FFMPEGX and what does the info at the top of the FFMPEGX Gui window say it is for FPS (or click the "info" button for a popup)?

Most modern DVD players support playing PAL. Hmmmm, can one create a file that is in NTSC video format and at the PAL FPS rate?

[Cecilio]

its not NTSC or PAL. its a downloaded avi. what pirates do, is they slow down the framerate, so that they can make there movie look a little better, i mean so they can keep a low bitrate, and a low size.

[BringthepainDane]

Ok, so which framerate should I choose in ffmpegX, or how do I get the video and audio to be sync?

[Cecilio]

hold on i never check that this was an ffmpegmux thing forum, if your using a mac sorry cant help you as i never used ffmpeg, but if your using TMPGEnc i will be glad to help you.

[gmackenz]

Whoa...Pie-rats! Never seen slowed down frame rates in the *cough* few movies/tv-shows I've downloaded (just for "research" mind you ).

Can't advise you to well then...I am assuming that playing the divx file the audio/video is in sync when using mplayer or vlc. I am assuming you've used Divx Doctor II to convert the file to a .MOV format (uncompressed the audio from MP3 to an audio format that quicktime can handle more easily...Does the resulting file still play in sync?). Now start the conversion with FFMPEGX.

If you are using (hopefully) a DVD RW disc, have you tried some of the different Frame rates in FFMPEGX? I'd try the 23.976 (NTSC Film) rate with DVD NTSC/DVD NTSC 16x9 (whatever matches your original video aspect ratio of the divx file)? This is all guesswork as I've never dealt with non-standard FPS files.

Takes some practice to get all this working for you. Bon Chance!

[Cecilio]

in TMPGEnc theres an option, that says 14.95 fps internally 29.97 fps. you can try that.
