mux + Scene detection + subtitling problem

[tomnil]

Hi all!

This is my case. I need some kind of software (or several ones) to solve the following problem. My budget for the solution is quite good if the solution is good.

I need a solution which can read demuxed files (that is, mpv & mpa files), mux them (join them) automatically (I have a solution for this part, so it's not crucial). After that, it should do scene detection on the mpeg file, and at each scene found, add a DVD-chapter (Editing the DVD-chapters after the scene detection is a must...) Also, I would like to add subtitles to the project, and finally, of course, either burn a DVD or generate an image-file.

The software must not rerender the files. That's important as well.

Any suggestions? I've downloaded and tested many trials/demos but nothing seems to be close to solving this.

I'm no expert and pretty new to the DVD authoring thing, but I think the reason your post has not been aswered by the "experts" is because it's not clear what your overall goal is.

Many programs do different things. Do your files have to be demuxed to mpv and mpa files? Are you ripping from a DVD? What are you using to author the project? Knowing these things might help folk reply alittle better.

The goal is simple:

A DVD with a chapter point at each new scene, preferrably with subtitles. The movie should be in in high quality.

It doesn't seem to exist such a tool (maybe except for Adobes Premiere Pro + Encore, but since I havn't seen a demo on those yet I don't know.... besides that, it's somewhat expensive)..

Hi tomnil

DVD-lab will do what you need, thouhg I'm not sure about subtitles. It can automatically detect scene changes and insert chapters there, though I'm not sure how accurate it is. It can certainly work with all the files you mention and will mux the audio and video at the final VOB file output. I think it is worth looking at. There is a 30 day trial version available and it's fully functional. Download it from here:

Install it and then ensure that you download the latest 1.3 Beta 2 update from here:

I've already tried DVD-Lab, and it had some serious troubles with the scene detection (it added either to few chapters, or too many - depending on the sensitivity level). Also, if I'm remembering correctly, you can't edit the chapter points after they're autodetected (atleast don't delete them)

Further, I think it's not capable of reading my source files (which is, a mpv file and a mpa file).

And, of course, subtitling is missing...

Some of the above might be fixed in the current version...

For subtitles support on DVDLab, you might try this:

Yeah well all scence dection programs are crap. You really need to either set the chapter points manually or every X minutes. As for subtitles there are work arounds for DVD Lab (see post above). But for a program with no work around (supports subs directly): DVD Maestro, Scenarist, Reel DVD, IFOEdit, Adobe Encore (only ones I know off).

Nearly all authoring programs allow you to import elementary streams (ie. un-muxed files). I would give up on the automatic scence select thou.

Tomnil,

you mentioned that the files are de-muxed MPV and MPA. Are they demuxed from VOBs or are they original footage?

If your source is a DVD, then you can extract the chapter points from the DVD structure (in time or frame format) and use them to set the original chapter points in DVD-Lab.

What I do when I want to set chapter points from scratch is the following:

I open the .m2v file with VirtualDUB-Mod and press the next scene button. It does almost the same thing with DVD-LAB, identifies large differences.

I view the movie in almost fast-forward (if you select 1/2 frame size) and skip most of the scene changes displayed only keeping the ones that are to my liking.

VirtualDUB also displays the current time of each frame, so I copy this time to the "time-line" of the authoring program.

I know it's a manual process but it's mostly automated. It takes some time (20min) but I don't have to do much or think about it - it's a good time doing a break and listening to some music in the back-ground...

[tomnil]

The source files is home movies, so it's not possible to extract existing chapter points.

Nevertheless, I've made some progress. First of all, I've loaded some 100Gb of movies to one of my drives with scene detection during capture (that means; I've got 360 files, one for each clip...).

Also, I've bought the cinemacraft basic encoder and written a small vbs-script to automate the conversion process to mpv & mpa (so now I've got 360 mpv files together with 360 mpa files).

What I've learned is also: Doing DVD requires the video and audio track to be seperated on the dvd - thus muxing them (joining the mpv & mpa into a mpg file) is quite unneccecary since the DVD-program will split them up again.... So for DVD I'm almost set - just trying to locate a good program which can handle the mpv & mpa files without rerendering. Any suggestions?

Alright.. but I've got another problem as well. After I've burned the high quality DVD, I would also like to keep a low quality copy of the file on my harddrive.

So I'm looking for a tool which can scale the movie (preferably the *raw* DV-movie). It should really handle commandline parameters, if possible Any suggestions here?

Also, I'm looking for a simple demuxing tool (which takes two files as input and outputs a final file). The commandline is needed here as well.

I'm clearing myself up a little bit:

I'm looking for a program that may create a DVD from the MPV/MPA files - yes.. but it should be able to play them as oe long movie, but with chapter points.. and without major clicking..

(The 360 files I've got is from a dance competition.. and you might see what the problem is if I need to manually add all of them.. and they're only from *one* competition, I've got a few of them..)

This seems to be a mission impossible..
