Weird ratio export issue

[mabbutt]

Hi,

In am new to the boards and after searching for a similar thread I am unable to find a solution.

I have created a short film using numerous clips. The footage is shot with a ratio of 16:9 and this is how it is viewed on my PC.

However if I export it to any format other than MPEG the first and last second of each clip stretches horizontally and then returns to the correct ratio (see images). I have tried every possible conversion with no luck. It is always the first and last second of a clip and happens for every clip in the film. The only time it doesn't happen is with the title templates.

Please can some suggest a reason and even better a fix for this problem as obviously it makes the film un-watchable?

If I need to provide any more information then please ask but I am not sure what else to add.

Many thanks!

Hi

And welcome to the forums

Seems very strange.............

First of all the first image (untitled2.jpg) displays as approximately 4:3
the second image (untitled.jpg) seems to display as 16:9 widescreen, which would be normal?

How it views on Cyberlink will be affected by the players settings, however it should default to auto detect. So I guess the problem to be with the video files.
--------------------------------------

1 / We need details of the properties of the original video clips used in Video Studio.
Right click a clip in the timeline and select properties, what are they? post an image of the properties window.
2 / What version of video studio are you using?
3 / What are you trying to make? a DVD or video for the internet, if DVD HD or Standard?
4 / What format are these problem clips?

Hi Trevor,

Thank you for replying so quickly.

The video should be in 16:9 widescreen. This is what I have filmed all of my clips in.

Please see attached the picture of my properties for the clips. I think this also shows the format of the clips?

I have tried playing the video in several players and they all display the same.

I am using Coral Video Studio Pro x4.

I am trying to make a DVD in the highest quality possible but I have tried various formats and qualities to see if I can eliminate the problem. The only way it displays correctly is if I convert it to MPEG. I am happy to have the final video in any format as long as it is high quality.

I hope I have answered all your questions but if not then please ask.

Many thanks again.

Hi

Those video properties are bog standard and are Mpeg2 compliant suitable for burning a DVD.

The frame size uses 704 x 576 whereas Video Studio would default to 720 x 576 however both are suitable to burn a disc
I have to say i have never used 704 x 576 types.

Are you saying that playing the original video files that you have trouble with the aspect ratio?

If you start a new project
Share Create Disc opens the burner module
Add Media Files Add Video---add one of the original video files
navigate to the last window and choose to create a Disc Image or DVD Folder, deselect Create Disc
This will burn the video to the same files as used when burning a disc, saves you creating coasters.
I generally use Disc Image this creates an Iso file which I play using VCL Media Player.

The DVD Folder option will create a Video_TS folder.

PS i'm guessing your camera records to disc?

Hi Trevor,

I only have trouble with the aspect ratio once I have created a DVD or similar file (.avi etc). The first and last frame is always 4:3.

Yes my camera does use a disc. Does this cause issues?

I will try the above instructions and let you know how I get on.

Thank you so much for taking the time to help me.

[mabbutt]

I will try the above instructions and let you know how I get on.

I tried both options with unfortunately the same result as previously. The aspect ratio changes for the first and last frame of each individual clip.

Hi

Are you sure this is not the media player defaulting to a smaller screen/frame when not playing the video.
What happens if you stop play mid stream?

Hi, I have tried to play the files in various media players with the same results.

If I pause the footage it stays exactly as it is displayed when played like a 'normal' clip.

It is only ever the first and last frame of each clip. Everything else in the middle displays as expected.

It also plays correctly when previewed in Coral Video Studio x4 and only changes once the file has been exported.

Very strange indeed, the frame size of 704 x 576 is a Pal standard, its anamorphic and resized to play as 16:9
The more usual frame size of 720 x 576 would be used as default. If you use Video Studio to render your video file to Mpeg2 DVD then 720 would be used unless you stipulated otherwise.

I am just thinking out loud here and do not think there should be a problem.

I have created several samples to your properties but cannot replicate the playback issue.

Can you make a sample available for download? some users have used "4shared" or similar share programs.

I notice the properties show the file size as 13Mb, you may be able to e-mail, view my quick guides for e-mail address.

I have cut the file right down as an example.

I hope this can be accessed but if not then please let me know.

I really do appreciate all your help!

Hi

Thanks for the sample, now I know why you named the post as Weird.
It does appear to be part of the video file, at least thats my impression of what I am seeing.
The clip reverts to 4:3 ish at 4 sec 14 frames for about 12 frames, very strange.

Can you provide one of the originals direct from the camera before you applied any edits.

I don't use a Disc Camera so have no knowledge of how you transfer the video to the computer.
If the camera came with software to do that you would be best using that.

By the way is it only this short clip that is affected, or are there other clips that show the same problem?

Hi Trevor,

Yes it is very weird

It affects every single clip in the same way.

I have tried to transfer the files from the camera to the computer in several ways to see if that is the problem. I have inserted the disc directly, used the camera software and also used Windows Explorer. All produce the same results. I have also tried to convert the original files directly from the camera.

I can not upload an 'original' clip as the entire footage is bundled into a Video_TS folder and I am unsure of how to separate them without first converting that file.

Hi

You say
"I can not upload an 'original' clip as the entire footage is bundled into a Video_TS folder and I am unsure of how to separate them without first converting that file."

The Video _TS is a folder created on any standard DVD Disc.

I do not know the capacity of your disc?

The main video files are called VOB, the first Vob may be for the menu if the disc has one.
All other Vobs will be approx 1 Gb, these are your video files.

Copy the Vob to the hard drive then rename to use the extension *****.mpg

You should be able to import these to Video Studio, from what you are saying I think the results will be the same.
The files will be 1 Gb, you can upload to 4 shared if you wish but will take a long time.
Otherwise upload the VOB before re-naming.

---------------------------

Do you have more than one disc to use with the camera.
Do you have the same problems using different discs.?

[canuck]

Perhaps you can create a short 10 sec or so video using the camcorder and then to upload that to a the file sharing site. I would think such a short clip should not be that large.
In that clip you provided, I find 3 problem frames and they are near the end. The 1st and last frame are fine. Also there is a series of transition frames. They must have been done afterward which means that the clip is not the raw clip from the camcorder.

Hi canuck

I wrote this in an earlier reply, what do you see at this point?

"The clip reverts to 4:3 ish at 4 sec 14 frames for about 12 frames, very strange"
