Hi

. . . . adjust a movie to fit on a disc the original chapters now are 1 sec further from as required . . . .

I presume you mean using the auto adjust option that popups if the project will not fit on the disc - is this correct?

If so, this adjusts the bitrate of the video to reduce file size on disc and should not affect the chapter positions as they are time based.

Without more information on what the source video files formats, resolution, framerate mode and framerate are, there are several possibilities which may be causing the time slip:

• video source frame rates do not match the frame rate for the disc TV standard your are burning to
• video source files are a mix of different frame rates eg 29.97 and 25 fps
• a video source file are a mix of constant and variable frame rates.

MediaInfo is the tool to use to analyse the video source files and determine the parameters listed above.

The fact that you have received no answers to your question would suggest, I think, that no-one has actually encountered this problem before and hence can offer any advice.

If I was dealing with a video which was "too long" for a standard single-layer DVD (and there really was nothing I could remove) I would look to burning it to a Dual-Layer disc, hence removing the problem you are seeing.

Do you know exactly how much "oversize" your project is?

PAL off air tape going to PAL DVD. 2h15m.

Made up of lots of stop & starts about 3 to 5 min recordings cause the tape clogged up. All knitted and joined so watched it in the project and it played fine.

As a dual-layer image they worked fine but trying both manual tweak then tried auto-to-fit they ended up 1 or 2 seconds after the chapter.

@mark-perry

You really do need to answer the questions that @johnebaker asked, but, again speaking personally, a video of 2 hours 15 minutes is going to have to be so "compressed" (in terms of bit rate) in order to fit on a standard DVD that the video quality is more than likely to be seriously degraded. Even without the problem of the "moved" chapter points!

Jeff

I used to have a Sony RDR HXD870 DVD recorder until the burner became worn but you could widely adjust fit a disc and 130 min was pretty good to (I usually made 150 min my max for VHS).

Specs: mainly Australia PAL off-air and official movie tapes. Why change NTSC yuck!

This tape was transferred until it clogged, went back a few seconds and overlapped the join by 1 previous frame checked it was ok and then kept going etc etc till it was all done.

All grouped afterwards. I used the preset video input so (after the fact) I added tiny bit of sharpness and a small tweak of contrast because it was a little bright. I compared the laptop screen to my Panasonic Blu-ray HDD REC/Sony TV of it as a reference on my TV to get the picture tone right.

(I was going to do it on that but went over 2 hr limit).

Chapters, last night I tried making backing 5 frames as a start but no joy so will probably a few more frames to a second before where i want them.

@mark-perry

You are still not actually answering the questions @johnebaker asked! Specifically:

Without more information on what the source video files formats, resolution, framerate mode and framerate are, there are several possibilities which may be causing the time slip:

video source frame rates do not match the frame rate for the disc TV standard your are burning to

video source files are a mix of different frame rates eg 29.97 and 25 fps

a video source file are a mix of constant and variable frame rates.

Please help us to help you!

In terms of your statement I tried making backing 5 frames, you earlier said each Chapter point was 1 sec further from as required. Was this "1 sec" an approximation? If not, PAL video runs at 25fps, so 5 frames change represents 0.20 of a second.

Hi Mark

To summarize from your posts - you are:

1. recording from a VHS recorder through a video capture device
2. stopping when the tape jams rewind a little and then continue recording after adjusting the overlap
3. you did not recording and save the individual recordings as single clips.
4. the tape is PAL and the recording parameters never changed.

   Is this correct?

   We need a bit more information:-

5. are the chapters all shifted by 1 sec, or is it incremental ie chapter 1 is 1 second late, chapter 2 2 secs late etc

6. are you adding the chapters to the project with the individual clips as recorded or exporting the clips to a single file and then loading this in MEP and adding chapters?.

If you are not exporting the clip project as a single file, I would suggest you do - use Export as Magix video option to get a .mxv file and then use the .mxv file in a new project adding the chapters and any other effects such as sharpening etc that you need.

HTH

Sheez.

All I asked was could i retain the exact chapters if I adjusted the movie to fit on the disc.

I'm not making my own Star Wars movie with 126 effects tracks in 4K super super SECAM in 300 frames per second and a 3D Terminator to boot.

All the answers and questions suggest I may have to shift the chapter points so they match where i want them.

It was originally recorded in one single taping in 1992. Using Magix simply required stop starts when it snowed up replaying that section was mainly fine until the next clog and etc, then did the chapters, then noticed the picture so rather than retape it all I "tweaked" it and authored as a single movie. The resulting DVD picture and sound quality is all fine its the chapters I need sorting.

Hi

. . . . All I asked was could i retain the exact chapters if I adjusted the movie to fit on the disc . . . .

Pleas re-read the last paragraph of my post above - that is a probable and easily workable solution - there is only one video to work with for adding chapters and that should not be affected by changing bit-rates to fit on disc.

In the project with the individual clips there is something going on with the video before the first chapter when the fit to disc adjust option is used.

John EB.

Sorry folks, but emmrecs was getting me really wound up after my best attempts to explain the situation.

So today I have tweaked the chapters a full second before where i want them and that brought them a few frames before the place where i wanted for every chapter (x 47 for this project) so that means further tweaking to less than a seconds worth of frames say 15-20 frames and that should hit the spot.

@mark-perry

It is very frustrating not to receive answers to the questions asked, as @emmrecs has pointed out, and the results of trying possible solutions to the issue you are having.

Additionally going off on tangents trying to fudge fix the issue is wasting your time and causing more frustration for you.

To clarify, I believe that in the project with the individual clips, there is something going on with the video before the first chapter that is causing the fit to disc adjust option to put the chapter markers out of sync, therefore you need to get that projects video clips into a consistent state ie as a single file.

To do this:

1. export the clip recording project as a single file - use Export as Magix video option to get a .mxv file
    
2. create a new project and import the mxv file to the timeline, add chapter markers and any other effect eg sharpening as required, save the project with a new name
    
3. burn the new project to disc.

Well (starting from zero) I've got

- 10 sec of nothing

- 15 sec of an old recording, that one was stopped so there's 5 sec of erasure signal but no picture as the Magix program mutes then in-between spot until it detects a signal. I did deliberately capture that section of audio from Audacity, inserted that into it project and allgned both the audio signals and picture until they matched.

I did click the Ignore those 2 blank sections message when prompted.

I don't need the first blank so I can cut that and drag the whole "movie" to zero.

* interesting when Magix tries to capture inbetween section it throws the pic + sound out of sync so thats why I grabbed the audio separately, started the tape from where it stabilisedvan then left space inbetween to reconstruct the frames of the tracking section and finally joined it all up which all went OK.
