Video image getting squeezed.
Hey, I'm new to Premiere (mostly used FCP in the past) but I just finished shooting this film, and now I am trying to edit it. The problem is when I imported the footage, the image looked really compressed, like the sides were getting squeezed. When I play the raw footage in quicktime, the image looks fine, real wide. The stats on the video are
1080/1280 progressive
frame rate 29.97...
pixel aspect ratio 40/33 (in Premiere it shows as 1.2121)
Now I shot it on a Panasonic HPX-170, using a 35mm adaptor, I don't know if that changes anything.
I tried a bunch of different project settings, some make the image a little less compressed, but none get it right.
I'd really appreciate some help on this.
Thanks in advance.
Looking into my crystal ball...
You used FCP to Log and Transfer the MXF clips into DVCPRO HD MOVs. The PAR is now being misinterpreted; it should be 1.5, which is the correct PAR for DVCPRO HD 1080i/p.
To fix this, select all the clips, and right-click/Cmd-click or Clip > Modify and select Interpret Footage. In the dialog that appears, set the Pixel Aspect Ratio to "Conform to: DVCPRO HD (1.5)." Once you hit OK, your clips will be correctly interpreted, and you can either use a DVCPRO HD preset that matches your footage (you'll have to customize your own, as there is no built-in 1080/30p preset, so just use the 1080/24p preset as a starting point), or you can drag a clip to the New Item button at the bottom of the Project Panel.
(By the way, this might actually be a bug in Premiere, at least with the way it interprets DVCPRO HD MOVs. If you have the MXFs, they would be interpreted correctly.)

I am trying to develop a chat application which has the webcam feature. I am using JMF for this purpose. I am creating this as an applet. The first time when the page loads and the user clicks the start button to start the video, the webcam starts and the video is displayed in a small area of the applet.
The problem is that, if the user clicks on any other buttons on the applet, the image gets resized. It scales itself in the horizontal direction. I have no clue as to why is this happeneing. I have tried using GridBagLayout, but still the problem persists.
Any help in this matter will be highly appreciated.
Regards,
SharadThis is the code which I am using. The start button is to start the video. After the video is started, clicking on the next button will resize the video. The next button loads another image on to the applet. The Image is on the left side and the video is being displayed on the right side. Clicking on the next button calls the class PresentControl.java.

Importing from Sony DV into iMovie & getting Darker video image
Importing from Sony DV (Video quality looks great on video LCD screen) into iMovie & getting Darker video image. After I import into iMovie the video image is darker, making in harder to edit. I appreciate any help with understanding how I can improve the video quality when importing.
Thank youWelcome to discussions!
You may just need to adjust your monitor.

Plus, it will look better on a TV than your monitor.

HD video gets squeezed into 4:3
I shot a bunch of video on a Route 66 trip, using an Samsung HMX-H204 camcorder. The clips are 1080p mp4-files, using HDV if I'm not mistaken. No matter what project preset I use, when dragged to the timeline the video's all end up getting squeezed in a 4:3 (or 0.75) aspect ratio.
So I'm seeing a 16:9 work area, where my footage is squeezed into 4:3 with a black bar on either side. I tried all project settings, from 1080i to SD widescreen and everything in between, but the result is always the same.
I use Premiere Elements 8 in 32-bit Windows 7 on a recent AMD something dual core processor and 2 GB RAM. The Samsung is a new camcorder, previously I used a Sony camcorder with miniDV-tapes, shooting widescreen footage in SD. Never had aspect ratio problems with those clips.Fred
Thanks for the screenshot. Very helpful. For now I am assuming that you are in a PAL location (seeing the 50 frames per second in the screenshot...the frame rate of 50 instead of 25 may be another issue which we will leave for now). The read out tells us that you are working with AVCHD (MPEG4 AVC/H.264) video.
This is what I would like you to do:
1. Open Premiere Elements 8.0.1 and set the project preset (new project dialog) = PAL AVCHD Full HD1080i25.
2. In the program, Edit Menu/Preferences/General, have a check mark next to "Default Scale to Frame Size".
3. Right click the Edit Mode Monitor, select Magnification, and have the set on "Fit".
4. Using Premiere Elements' Get Media/Files & Folders, import your AVCHD 1920x 1080 16:9 video into the program. (You will see your video in the Organizer.)
5. Drag your video from the Organizer to the Timeline. Are you seeing a 4:3 version of it in the Edit Mode Monitor?
6. If so, click on the Project Tab in the row below the active Organize (Blue) Tab to bring up the Project Media View.
7. In the Project Media View, right click your video in the list to bring up the Interpret Footage dialog.
8. In the Interpret Footage dialog, under Pixel Aspect Raio, dot the "Conform to:" and change the setting = Square Pixels (1.0). After you click OK to that, see what your video now looks like in the Edit Mode Monitor.
Miscelleanous
1. You can also use the Interpret Footage dialog for Frame Rate considerations.
2. Although the gspot read out does not give a reading for PAR (Pixel Aspect Ratio), the PAR can be calculated from the SAR and DAR values given since PAR = DAR/SAR and, in your case, 1.778/1.778 = 1.0. The DAR is Display Aspect Ratio and the SAR is Storage Aspect Ratio.
3. What is the duration (seconds, minutes, hours) of the video that you have been trying to use in Premiere Elements 8.0.1. You are working with AVCHD which is a very resourve demanding format, and it appears that you have 2 GB RAM installs that probably translates in much less available and you do not say how much free hard drive space your computer has. But, if the video in question is only of a few seconds duration, we should be able to work through this pixel aspect ratio issue.
Let us see what happens. We will be watching for your results.

Flash video image problem with newest nVidia driver
I've got a very weird display error since the last update. Basically, whenever I play flash video and afterwards close the browser (chromium), any purely black surfaces will display the full flash player image. The effect is only visible in the "first" window of a xmonad tab, that means if I cycle the window positions it will be in a different window. The others are not affected. When I restart X, I can see the flash video image flashing up shortly on the black screen. Restarting X fixes the issue. I cannot take any screenshot of the problem because the error is NOT visible on the screenshot. Therefore I suspect that some frame buffer used for the flash player is not getting cleared properly after exiting the browser, but it's really little more than a wild guess.
As there are multiple components involved, I'm at a loss of where this might be coming from. I hope someone might be able to shed some light on this situation. Please post here if you have the same problem or have any idea why this happens!
My setup:
-nvidia 260.19.36-2
-flashplugin 10.2.152.27-1
-chromium 9.0.597.94-1
-xmonad 0.9.2-1
-xmonad-contrib 0.9.2-1

if you asking about a bug reported on arch linux bugtracker, then you are doing it the wrong way.
flash and nvidia are closed source, we can't do anything. A better place is to submit bugs to nvidia and adobe.
Now i see that nvidia 270.26 was released. Maybe you want to check that out:

Re: How to display Graphical objects over streaming video images??
Hi, have you figured this out yet and if so, what is the answer?
There are not just several steps that are required but also you need a very fast CPU (or you have to work with very very small images),
The basic approach is to put the WebCam (video) input into a Processor and to add your own implementation of a "javax.media.Effect" to the processor (let's call it Overlay3DEffect).
Then you can:
- transform the input Buffer to a java.awt.Image,
- get the Java3D image to be overlayed
- overlay the WebCam image with the relavent part of the Java3D image
-convert the resulting Image back to the output Buffer
The above processing has to be performed In the
public void process(Buffer in, Buffer out)
of your effect (Overlay3DEffect) -
How to send files like audio,video,images and text via RMI..
Hi everyone,
As I am working under a project, my own, of creating a chat machine, I've thought to make it capable of doing everything that MSN or yahoo MSN can do. Till now I've just been able to send messages and some small icons as expressions. So, my next step will be making my progam able to send even other files like audio, video, images and text to the person on the other machine to whom I'm chatting. But as I don't have any idea on how to start doing it, I want anyone who think he/she can help me to give me the basic logic that is used to do so. I would very much appreciate it. I've used vectors to store the text messages which is visible to all the users using the chat program enabling them to see various messages in it.
thank you...
JayHi,
Now, I got stuck because the code doesn't seem to work well. For large files with around 40 mb or more size couldn't be sent. I have constructed the code, just rough sketch, as follows:
** In the Server Implementation class I've used FileInputStream to read the contents of a file that is sent as an argument to the method.
** Similarly, in the client side I've used RandomAccessFile to save the received array of bytes.
public void sendFile(File f)
ChatServer cs=(ChatServer)Naming.lookup("rmi://localhost/ChatServer");
cs.readsAndStoreTheFileInTheServer(f); // In the Server Implementation the contents of the file is read and saved in an array of byte. later method is invoked by the client to get the array of the saved byte.
cs.message("-Accept-"); // When a client receives this word then a JComponent with accept and cancel button will be constructed from where other clients can save/cancel the sent file.
}For small size files this code works well but for files more than 40 mb of size it is useless. I wonder if there's any other alternative.
regards,
Jay -
When uploading videos to iWeb, the video screen gets cut off at the top. It only happens in Firefox, but not in Safari. Has anybody else had this problem?
I'm using pure HTML5 for mobile websites although you need to provide an OGG file for Firefox. See the movie page on this site...
http://mobile.ezmacwebdesign.com/
If you don't have an iPhone, grab the browser handle and drag it to the left to reduce the width to see how it responds to mobile devices' fixed width browsers .
This will play in all modern browsers and on mobile devices. You can use QuickTime Pro for the OGG or OGV conversion or get the freeware Miro Video Converter...

If you only want to upload an MP4, you can use a flash fallback player and this will cover Firefox and those geriatrics that still use older versions of Internet Explorer....

If you use any of the four fallback players above, take advantage of the fact that you can add a poster image and stop the video file from preloading. This makes for a faster page download time.
You can also achieve this using HTML5 by adding preload="none" and poster="URL to the poster image" into the code shown on this page...

Can I adjust the video image I receive when making a Skype call?
I have made my first Skype call and the video image I see on my computer is very dark and I am wondering if there is some way to make adjustments? Do I need to get some specific software for viewing? I don't really understand the whole thing but I sure would like to have a better quality image of the person I am speaking with.
I appreciate any help I can get! Thank youThere's nothing much you can do unless the person
you skype to turns on some lights over their computer.

Trouble Encoding Still Video Images
Hi All,
Newbie Premier user struggling to finish first video. Here's my problem, and hopefully someone out there has encountered it before:
I have finally finished creating a very basic, short (~ 2 min.) video (4:3 interlaced; SD DV-NTSC, ) clip containing several interspersed title frames and a single JPEG image serving as my establishing shot. For some reason, the high resolution JPEG image appears jagged and blurry once imported into Premier Pro CS4. After several hours of meddling around I have discovered an interesting phenomenon whereby increasing the magnification percentage from 'Fit' to '100%' in either the Source OR Program monitors restores the image quality. However, when this is done the video quality appears severly interlaced. Can someone shed some light on this issue because I am about to pull my hair out. Thanks.Hi Jim,
Thank you very much for taking the time to read and reply to my question.
I have rendered out to a .mov file using the DV-NTSC authoring codec and the quality of the video still image is very jagged and blurry. My export settings are as follows:
Container: Quicktime .mov
Codec: DV-NTSC
Qualty: 100%
Scan: Progressive ( Video looks great...image degrades) ; Interlaced (Odd/Upper) field (Image looks great...interlace artifacts predominate)
|| ||
V V
ASR: 0.9091 1.0 (sq.)
Since my first post I have imported the video into Sorenson Squeeze 5 and compressed using the On2 VP6 Pro codec with Flash 8+ HQ presets. The file size has been reduced ten fold and the video quality has held up well. I have also noticed and improvement in the clarity of the title slides, but the image issue persists. Any thoughts on what is going on here.
Thanks,

Still images get mixed - Premiere elements 9
I make a series of say 3 or 4 still jpg images as titles for my movie. All with identical background but with different text. When I drag them to the timeline the first one persists but the others in the sequence will not show when I play them in the preview window. This does not happen if the images are completley different. Renaming the files has no effect. What is happening?
Bob,
I understand what you mean about the appearance of movie clips in the timeline, I don’t think that is the problem. With every other video editor I have used if I drag a number of still images into the timeline they will all behave like separate clips for however longer I want them and they will each show up in the timeline and in the preview window as I scrub along. At the moment instead of a mini movie of 4 still images I get a movie of the first image in the line repeated for times. The other image files are named in the timelinebut cannot be viewed in the edit and they don’t appear in the saved movie I am doing something wrong somewhere.

Preview window in premiere 10 will not show view video images
My Premiere 10 preview window will not show video images. There has been some on-line discussion that nVidia GeForce video card automatic updates is the problem and it has been suggested that I roll back to a previous card however the rollback button does not light up and can not be activated. Also I'm not sure that I'm using the correct settings for the preview window, what are the default settings?
I recommend that you try your question in premeire forum, so you have a better chance of getting an answer.

Video image from webcam resizes
I am trying to develop a online presentation application which has the webcam feature. I am using JMF for this purpose. I am creating this as an applet. The first time when the page loads and the user clicks the start button to start the video, the webcam starts and the video is displayed in a small area of the applet.
The left side of the applet displays the images. When the user clicks the next button, the next image from the vector is displayed and the image label displays the image number as 2.
The problem is that, if the user clicks next button , the video image from the webcam gets resized. It scales itself in the horizontal direction. I have no clue as to why is this happeneing. Is this something due to the layout problem or JMF ?
Any help in this matter will be highly appreciated.
Regards,
SharadI guess its because you are having a BorderLayout. If with a borderlayout, components added will strech both ways (horizontally and vertically) but you seem to say that the video image strechs only horizontally, maybe components added to NORTH or SOUTH of a borderlayout would do that.
Anyhow, try to set the layout to FlowLayout -
IMovie imports a still video image
When I import a video into iMovie, I get the full audio but only a single still video image. What's up with that?
I didn't film the video, so I'm not sure what kind of camera was used.
Here is a screenshot of the Quicktime Inspector:
And here is a bit more information about my situation: The video plays fine off of the thumb drive it was given to me on, and it plays fine off of my hard drive. But when I import the video into iMovie, all I see is the one still video shot while the audio plays beneath it. I've tried this on two different computers and on both of them, the video is frozen once it's imported into iMovie.
Bizarre.
I appreciate your help! -
In FCE, how do i retrieve lost video images for my edit?
In FCE, a project that i have worked on has lost some of the video images from an original file imported from iMovie. The source footage still remains in iMovie. How do i get the lost images back, without having to re-edit the whole thing?
Also, please, what is the short cut to "highlight all" or select all" in FCE?
Thanks for your help!Import the source footage from the iMovie events folder and add it in.
