i have a few music vids that are pal and want to convert to

[bodybuilders1]

hi folks. i have a few music vids that are pal format, and i want to convert these to ntsc to put on my dvd disc, with no video loss or mess up.
i have used a program that does this, but it makes my file look not like the original, which is what i want, an exact duplicate of the original, only in ntsc.
also how do i demux a music vid and remux with audio from my music cd, to match the lips of the music vids (basically i want to take out the clean version audio, and put in the dirty version of the audio to the vid)
thanks!!

I'll take these one at a time:

PAL --> NTSC: Have you tried any of these guides?

If so, which one? I don't think it will be possible to make it look like the original since the framerate adjustment is 25 --> 29.97fps. The encoder will have to add "dummy frames" in, and this may give the video a "jerky" appearance. I'm afraid it is unavoidable.

Demuxing audio, remuxing custom audio: TMPGEnc can do this, as well a these applications:

ImagoMPG-Muxer looks to be your best bet for this.

As for syncing of audio to video, you'll need to match the length of the new audio file to the length of the video. Also, you'll need to be aware that the video may run for a while before the audio comes in so take this into account by adding silence at the start of the audio clip. Also, bear in mind that DVD needs audio to be at 48KHz, not 44.1KHz. You need to encode into MP2 format. ffmpegGUI will convert a WAV or MP3 to MP2 for you - I'd suggest that you keep your audio in WAV until you convert to MP2 to preserve quality.

Here are some audio editors you may find useful:

thanks a mill bro, i'll check it out!!

hey buddy, quick question. how much silence do i usually add to the begining, before adding audio? and is there a guide somewhere?
thanks again.

There can't be a guide because all songs and videos are different. You need to work it out for yourself - it's going to be a pain but that's the only way I know of that will allow you to mux a different audio track to a video and maintain sync. It's going to be trial-and-error.

Maybe someone else will post up who knows a better method of doing this.

[bodybuilders1]

i'll work on that.
thanks again.

hey bud, back again with another question for you. by the way, i appreciate all the help.
Now i have noticed that some music vids will have a skit in beetween the song, how do i stop the song that i am muxing in so the skit could play, and then continue the song, without the silence that i will get in the beging of the audio? i have noticed, that this is what is done on alot of vids. i also have noticed that a few vids even have an intro skit, which then leads to the song, but i don't hear the silence, it just starts where it supposed to start. how is this done?
thanks again.

I had a sneaking suspicion that you may encounter this. Basically, the video has extra parts in it that the MP3 or WAV of the music you got from your CD collection doesn't have.

First job is to convert to NTSC and make sure the audio is still in sync (by reducing how long it is - speeding it up - in an audio editor) as per the guides. You must do this to compensate for the faster framerate. Convert to NTSC and find the exact length of the video, then match the original audio up to this.

If you then open up the audio in a package like Cool Edit, you can:

- Open the audio from the original music video (File --> Extract audio from video)
- Note the amount of silence required at the start
- Find the exact start and finish times of any interruptions
- If you want these, highlight them, right click and select "Copy to new"
- Open the new audio file
- Place silence/intro on
- Find the start times of any interruptions and either put silence in, or hop back to the copied-out parts from the original audio and paste them in
- Eventually, save as a WAV and compress to MP2 using something like ffmpegGUI.

Basically, you need to:

- Convert to NTSC
- Sync the audio up - you can do this in many audio editors
- Open the original soundtrack and note down the intro silence and timings of interruptions
- Open the new audio file and compensate
- Save as WAV and encode to MP2 for muxing.

Hopefully this is clear - I'm not brilliant at explaining things. You may not need to fiddle with the audio length - there may be a method of converting PAL --> NTSC that deals with audio at the same time, but I have never attempted one of these conversions so I don't know.

Sadly, there is no easy way to do what you're wanting to do. This is the way I would do it, anyway.

Best of luck,

cobra, thanks a mill bro, i will try this painstaking task.
thanks.

[bodybuilders1]

ohh, and when you say, convert to ntsc, you mean the video right? then after conversion of the video, continue with the rest of the process right?
thanks again.

That's what I mean. When you convert PAL to NTSC DVD you are going from 25 frames per second to 29.97. This means that the video will play back faster, so you have to make the audio go slightly faster too, otherwise it will lose sync.

I agree on the painstaking task, too. It will be worth it in the end, though.
