how to change frame size (xvid)?

[kthan]

I have two video files (xvid) and they have different frame size (640 x 352, 624 x 352). Because of this, I cannot join them and make one avi file (to fit them into one DVD).

I initially tried to find a joining software (like avi joiner or quick avi joiner). But, they either require same frame size or did not accept xvid format.

Please let me know how to change the frame size of one video file to match to the other.

Hi-

One will have to be reencoded to the same resolution as the other. Better would be to encode them for DVD separately, and then join them at the authoring stage. At that time they'll have the same resolution, 720x480 or 720x576, depending on whether this is for NTSC or PAL. The reason that way is better is because by reencoding one of the XviDs, you'll be degrading its quality even further, plus it'll take more time unnecessarily.

Thanks for your quick reply.

I am a newbie. So, I am wondering how to join multiple (two) video/audio files in an authoring program. I doubt how two files (50 min each, same series episode #1 & 2) can be arranged sequentially (play #1 first and then #2 with no pause/break in transition). It seems like many people joined two AVI before encoding because two may easily be messed up if two titles in one dvd. You seems to suggest I can merge two encoded video/audio files into one Video TS/Audio TS in an authoring program by keeping their sequential order/sync. Let me know the details if possible. Thanks.

I don't understand. When authoring, you load the 2 videos, one after the other, and you load the 2 audios, one after the other (assuming they're all DVD compliant at that point). They'll wind up in the same PGC, no gap between the 2 parts or anything. There's a slight chance you'll get some kind of a "pop" where the audio is joined, but you'll often get that even when joining AVIs. Maybe not all authoring apps allow for it. I don't know. Muxman does. If you insist on reencoding, if you have AviSynth:

AVISource("C:\Path\To\624x352Movie.avi",False)
LanczosResize(640,352)

That disables the audio. Extract it beforehand and mux it in after the reencoding is done. Load that script into VDubMod, set up XviD to encode, and encode.

Or, open one of the XviDs in VDubMod (I would also recommend extracting the audio, and loading only video, with no audio included), resize, set up XviD, and encode.

Remember though, when reencoding, you have to match several parameters or else you won't be able to join them afterwards anyway, even if they are the same resolution

Those are a couple of ways. However, I suspect this project may be beyond your capabilities at the moment. Prove me wrong. I'm telling you, encoding them separately for DVD and joining them at the authoring stage is easier.

Others may have other suggestions.

resurrecting this topic from the dead, I'm having a similar dillema. I am making an Episodic DVD with DVD-Lab Pro and would like for the entire VTS to be one movie containing every episode instead of 7 separate movies in the same VTS. That way I can make chapter playlists and it will be a more functional DVD on the whole, especially in regards to the 'Play All' feature.

But the XviD's are all from different sources. Some are PDTV while others are HR PDTV. The audio shouldn't be an issue because I've got everything converted to 2-channel AC3 at the same bitrate. But how should I go about joining them? From what I've read, it seems like joining the XviD's themselves is out of the question. But I like the idea of joining the encoded files - is there a way to do that in DVD-Lab Pro? Any help would be greatly appreciated, thanks.

That way I can make chapter playlists and it will be a more functional DVD on the whole, especially in regards to the 'Play All' feature.

In DLP you can do this by adding a "playlist" (right click in connections window). Then just add all the episodes and from your menu connect to this playlist. I have made a lot episodic DVD's and this is how I go about doing a "play all" link.

Yes, I know that and that is what I have been doing to make my DVD's but that doesn't change the fact that it creates a VTS with 7 separate movies. Doing it that way isn't the greatest for the 'Play All' feature because you can only skip through chapters on the video that is playing at that time; you can't skip to the other episodes in the VTS. To do that, you have to skip to the last chapter in the current episode, then either fast forward or watch the last chapter until it begins the next episode at which time you would have to do the same thing over again to get to the next episode and so on. Just not the best for Episodic DVDs.

This is sort of hard to explain. I want to only have ONE video file to deal with, containing all the episodes one after the other, and then create 'Chapter Playlists' for each episode. That would be much better for me. So joining the encoded DVD files seems like the best option...

you can't skip to the other episodes in the VTS.

I have 4 dvd players and they ALL can skip to the next episode so i dunno what you're talkin about.

hmmm..... you're absolutely right. I just tried it on my other DVD players and it works fine! I had been using my Xbox before and it wasn't working correctly. I no longer need to re-think my DVD making process, problem solved! Sorry for wasting anyone's time.
