Splicing video

[seekermeister]

The output from a movie that I just encoded, came out atypically, in that instead of a single file, it had four, as seen in the screenshot. Of course, I can play the sections together as a batch, but for reasons that don't see any point in going into, I want to splice these sections into one file as they should be.

After a bit of Googling, it seemed that the common answer to this problem was to use Windows Movie Maker, but of course, in W7 that means Windows Live Movie Maker (don't know if there is a difference or not?).

When selecting that wlmp file, all that it does is to reopen the files in WLMM, where it will play the files in sequence, but is notin a fashion usable in VLC. How does one create a TRUE splice, useable in any player of choice?

Recoding would be a lst resort IMO, as its times consuming, and you end up with more quality loss.
This just remuxes, and is rather quick.


As far as the encode coming out in Multiple files, is ther an option in the encoder you are using to "Split" ?
Perhaps disable it if so, or change it to a really high value, like 50GB.

Ive actually not had this happen before, so a bit confused as to why it would encoding it that way.

 

[seekermeister]

I shall reply by saying that I don't think that the problem was produced by any settings used in the encoder, because they are the same as I've always used, and this is a first for this problem. Actually, it failed altogether with WinX DVD Ripper Platinum, because it always terminated with a *success* window, after only running a couple of minutes. After going through their FAQ, it seemed that the only viable answer that there was something odd in the fashion that the DVD was written. I suppose that is possible, since the DVD was produced in Korea.

What I did show in the screenshot above, was made using DVDFab, and though it has failed in a variety of ways, never quite like this. I will now try the link that you provided and cross my fingers.

At first, it appeared that it worked properly, but after noting the warnings as seen in the screenshot, I ran the first few minutes of the movie to check. It started out as expected, but in short order, the voice audio disappeared, while the music played on. After maybe a minute, the voice audio continued, but where it had left off, not where it should have been. The gap between audio and video was so great, that not even calling it out of sync would be a good description.

The warning in the screenshot was so vague to me, that it is useless, unless you understand it better?

Remux is the wrong word to use in this situation.
Remux is what you do when you combine different signals back together, like an Audio, Video, and Subtitle file into one file.

I've used this program to join some video clips in the past,
Video Joiner/Merger to join video, AVI Joiner, MPEG joiner, join AVI,join MPEG.

 

[seekermeister]

Thanks, but the trial version will allow only 2 files to be merged, and I'm not inclined to buy it just to test it out.

 

[Zepher]

join 2, then join the joined one with one more and then do it one more time.

 

[seekermeister]

Hmm, after thinking about it, I decided to give BoilSoft another shot, by doing multiple joinings of sequential files, two by two. However that produced an error, saying that merging wasn't possible, because the files were of a different frame rate. Rechecking the main window, the first file was at 29.97 FPS, as expected, but the second was only 23.976 FPS, even though all of these files were created at the same time, without changing any settings.

As too often is the case, the more that I dig, the deeper that I get, without finding the bottom.


EDIT: Didn't see your last post before posting this, but we seem to have been on the same frequency.

[pacinitaly]

can you choose the timeframe

 

[seekermeister]

If by time frame, you mean the FPS, then yes I can choose, but oddly enough, when I just reencoded the video from scratch, I found that the first section was 876 bps, while the trailing 3 sections were only 768 bps. If I understand correctly, those rates can be translated into FPS, such as 29.97FPS, so I sped up the later three sections to equal the speed of the first.

After completing the encode, I played each section for a few minutes, and while not noticing much, if any difference in the audio or video character in the last 3 sections, the first one was still messed up by there not being any voice audio, only music and sound effects. I hate to think it, but I'm beginning to feel that this video is a lost cause, and will only be able to play it directly from the DVD.

 

[Hogtowner]

I believe you've got a funky DVD there. The 30 fps rate is NTSC typical, and the 24 fps rate is PAL (you know this, I'm betting). You can use DVDFab to alter the frame rate. I am not sure what you are referring to with the 876 bps figure, unless it is the bit depth or encoding rate which is independent of the frame rate. My gut instinct is, along with you, to slow down the NTSC segments to the PAL rate. Once you have them all at the same framerate, you might be able to join them. Good luck. Let us know how this turns out -- very interesting problem.

 

[seekermeister]

Yes, that is probably what I deserved, since I saved a buck or two buying from overseas. You might be right about slowing the first section, but fast or slow, it's no good unless all of the audio is audible. What is confusing is that the video sounds and plays normally from the DVD, yet is so muddled when encoded. Maybe those Koreans have figured out a new kind of copy protection. I will solve my problem by never buying Korean again.

May I join in here?
I assume you started with a commercial DVD. That being so if you open the DVD you will see two Folders AUDIO_TS and VIDEO_TS. The Audio one is empty but the video folder will contain IFO, BUP and VOB files. The VOB files are the ones you need. Transfer them to your hard drive. There may be a few smaller files but there should be a block of 3 or 4 files. 2 or 3 of them will be 1,048,404 Kb that being the maximum that a VOB file will take and one a smaller size making up the total for the video. The smaller files may be menu, trailers to other films, adverts etc.
The VOB extension is really not a format but a container for an MPEG file. If you rename the VOB's to .mpg then import them into a video editor in the order they are on the DVD, you will then be able to create an mpg file of the whole lot. This can be anything up to 4.7Gb in size. If you stick to mpg throughout and where possible tell the video editor to NOT re-render compliant mpg files you will keep rendering to an absolute minimum and thereby retain the best video quality.
If you can't transfer the files from the DVD then the disc is encrypted so it could be argued that you should not be copying it anyway.

 

[Wishmaster]

Are you encoding directly from the disc?

I agree your better off copying the disc to your HD, then encode it from there.
Ive never had a dvd encode into several pieces like this. Its a bit odd.


You may also wish to try ripping just the Main movie to the HD, and then choose the very first .VOB that .99 GB in size as the start point when you encode it, (in the Video TS folder)

It should, link the rest together automatically creating 1 single file.

When selecting that wlmp file, all that it does is to reopen the files in WLMM, where it will play the files in sequence, but is notin a fashion usable in VLC. How does one create a TRUE splice, useable in any player of choice?

What you have done in WLM is to save your project as a wimp file which you can only open in WLM. What you need to do is save the movie as a wmf file. This can be done by pressing the save movie button near the top right corner. You can select different qualities of file in the dropdown (press the down arrow) or just accept the default(press the icon). Once selected a file save dialog will appear so that you can name your movie, then in will proceed to encode the movie as a wmf file. This can take some time so be patient. After completion you can play this file in any player that supports wmf files. Oh you don't actually have to save the project if you don't want to unless you want to make further changes to it later.

I think I must be missing the point here. I thought seekermeister was trying to create a file just to play on his PC. The VOB are already MPEG files to why is it necessary to encode/render them to a different format? This always leads to a certain loss of quality. A mpg file will play on all the regular players that we use!

I do not understand all of this well enough to fully address your question, but there are 4 VOB files which contain this video, and I only want one file as the final product. Yes, a VOB file will play in it's current form, but my movie collection software is not setup to detect a file with a VOB extension. I want all of my video to be in either mpg, mka or flv. I'm limiting it in this fashion so as to decrease the possibility of some kind of incompatibility in any of the programs that I use.

I am unclear about the necessity of decrypting, because when I simply copy a VOB to the hard drive, it still plays okay in VLC, but then that would require adding all of them as a batch, rather than as a single file.

For simplicity in my personal dealings with the files, as well as the need for uniformity for inventorying videos, they do need to all consist of a single file.

Beyond this, a lot of other considerations have probably gone over my head.

 

[mitchell65]

Then just rename the four VOB files to the .mpg extension. Import them into Windows movie maker and save that to one mpg file! Do you have a video editor installed? If so we can use that.

 

[seekermeister]

If by video editor, you mean Windows Live Movie Maker, then yes. I copy/pasted the sections to the hard drive, renamed them to an mpg extension, loaded the sections into WLMM and then selected Save Movie. I do not yet know how well this will work, because it has already been saving for ~40 minutes, and still has 50% of the file to go. It sure seems like a lot of time just to save a file, since I assume that it is not doing anything else. I did notice that even though I renamed the sections to mpg, it changed them again to wmf, which I do not want. Can I simply return it to a mpg extension after it is complete?

Since I just copy/pasted the sections, I also assume that the encryption is still there, so it makes me wonder what the purpose of the encryption is...just to prevent copying to another blank DVD?

WLM always saves the movie as wmf. You have no choice here. Depending on how big the files are it can take several hours. If you want a choice of file format use Any Video Converter. You can use this directly from the VOB files. Free Video Converter - Any Video Converter Free Version - convert video to any formats, avi to MPEG, avi to MP4, flv to MPG
