Use this document to resolve problems that occur in Adobe Premiere Elements when you try to import video files, or when you play imported video files.
If an imported video file exhibits basic playback issues, see Troubleshoot Project and File-Interpretation Settings. Basic playback issues include stuttered or flickering playback, or video that appears blurry, fuzzy, pixelated, stretched too wide, or squeezed too thin.
If an imported video file exhibits more serious playback issues, see Troubleshoot File Formats and Codecs. Serious playback issues include upside-down video, no video, no sound, colored blocks or stripes, or playback that ends prematurely.
If Adobe Premiere Elements freezes, closes, or returns an error when you try to import or play a video, see Troubleshoot File Formats and Codecs. Error messages include "Unsupported audio rate in file" or "This type of file is not supported, or the required codec is not installed."
If you are working with MPEG-2 or VOB files, files recorded with a digital still-image camera or an ultra-compact tapeless camcorder, or video files purchased from an online media store, see Notes About Specific Kinds of Video Files.
Complete the following solutions in order. After you complete each solution, test the playback of your imported video files in Adobe Premiere Elements. If your imported files still play incorrectly after you have completed all the solutions, see Troubleshoot File Formats and Codecs.
Sometimes a mismatch between an imported file and the settings for the Adobe Premiere Elements project in which you are working causes playback problems. For example, widescreen video files appear squeezed if you use them in a nonwidescreen project. Standard-definition files appear blurry if you use them in a high-definition project.
Knowing basic information about an imported file helps you choose appropriate project settings. Right-click a file in the Project view* and choose Properties. The Properties window shows the file's frame size (as "Image Size"), frame rate, and pixel aspect ratio.
* For more information about project view, see the "Projects / Viewing a project’s files / Project view overview" in the Adobe Premiere Elements Help.
To create a project and choose project settings, do the following**:
** For more information about project settings, see "Projects / Project settings and presets" in the Adobe Premiere Elements Help.
Rendering previews*** sometimes improves the smoothness of playback of imported video files that you have placed on the Timeline or Sceneline.
To render previews of clips within the Work Area on the Timeline:
*** For more information about rendering previews, see "Arranging clips in a movie / Previewing movies / Render an area for preview" in the Adobe Premiere Elements Help.
If Solutions 1 and 2 do not correct playback problems, use these additional methods, as applicable:
**** For more information on setting the pixel aspect ratio of a clip, see "Importing and adding media / Working with aspect ratios and field options / Adjust pixel aspect ratio for a still image or source clip" in the Adobe Premiere Elements Help.
***** For For instructions on using the Field Options dialog, see "Importing and adding media / Working with aspect ratios and field options /Set field options for imported interlaced video" in the Adobe Premiere Elements Help.
Video-recording devices and video software applications encode files in a specific file format, such as AVI, QuickTime (MOV), and Windows Media (WMV). For a list of the file formats that Adobe Premiere Elements supports, search "Supported file formats in Adobe Premiere Elements <your version>" in the Adobe Knowledgebase.
Some video file formats, including AVI and MOV, are container file formats. The data inside these container files is encoded according to a particular codec. Codecs are algorithms for compressing video and audio data. Many different codecs exist.
For example, an AVI file can be encoded with the DV codec, a commercial codec (such as DivX), a Motion JPEG codec, among others. (Camcorders that record to miniDV tapes use the DV codec. Some still-image cameras use the Motion JPEG coded.)
Adobe Premiere Elements sometimes cannot decode video files that were created with a poorly designed codec or a codec that is not installed on your computer.
Knowing the format and, when applicable, the codec of the files you are working with helps you use these solutions. To gather this information, do one or more of the following tasks:
Some video files are encoded with codecs (DivX, Xvid, 3ivx, and so on) that are not installed by default with Windows or Apple QuickTime. You can download and install additional codecs on your computer. For example, to play DivX-encoded AVI files, download and install the DivX codec.
Installing a required codec usually enables you to use media-player applications, such as Windows Media Player, to play files that were created with that codec. Further, installing a required codec sometimes enables correct playback of those files in Adobe Premiere Elements.
Installing a codec doesn't necessarily resolve problems in Adobe Premiere Elements that occur when you import or play files created with that codec. The technical requirements for editing video files are more stringent than the requirements for playing video files. You sometimes have to transcode (convert) problematic files (see Solution 6).
Codecs are available from codec publishers' websites.
Important Note: Only download codecs from established, verifiable software publishers. Avoid downloading "codec pack" software. Installing a new codec typically causes some video or audio files to become unreadable. Back up all your files before you begin.
If you experience problems importing or playing files that are all the same format but are from different sources, the problem is likely that a poorly designed codec is installed on your computer. Or, it could be that multiple codecs are installed for the same video format. These situations often cause codec conflicts.
To resolve codec conflicts, disable or remove third-party codecs.
To remove third-party codecs (particularly "codec pack" downloads), use Add Or Remove Programs (Windows XP) or Programs And Features (Windows Vista).
Not all codecs can be removed using the Control Panel. For instructions on how to disable or remove other installed codecs, see these TechNotes:
Use other software to transcode (convert) video files that cause problems when you try to import or play them in Adobe Premiere Elements. Then import the transcoded files.
You can transcode a file within the same format (for example, transcode a 3ivx-encoded AVI file into a DV-encoded AVI file). Or, you can transcode it into a different format (for example, transcode a VOB file into an AVI file).
To preserve image quality when you transcode a video file, choose an uncompressed or low-compression output option in your transcoding software.
The following list includes some of the Windows applications that transcode video files. Other transcoding applications are available and could be better suited to your workflow.
Disclaimer: Adobe doesn't support third-party software and provides this information as a courtesy only. For assistance using third-party software, contact the software publisher or see the software's documentation.
MPEG-2 files are highly compressed. VOB (video object) files, which are used on DVDs, are variants of MPEG-2.
To improve the smoothness of playback of MPEG-2 or VOB clips on the Timeline or Sceneline, render previews of them (see Solution 2).
Because MPEG-2 and VOB files can be encoded with settings that vary greatly, not all imported MPEG-2 or VOB files play correctly in Adobe Premiere Elements. Transcode problematic MPEG-2 or VOB files (see Solution 6) and then import the transcoded files.
Many digital still-image cameras have "movie" modes that create video files (commonly AVI or QuickTime files). However, these video files generally do not compare favorably to videos that digital camcorders record. Many still-image cameras use lower frame rates and smaller frame sizes than camcorders.
If you are working with video files from a still-image camera, see the camera's documentation. Or, contact its manufacturer for details about the video files that it creates.
If you cannot import or play files from a still-image camera, try installing a codec (see Solution 4). Many digital still cameras encode video with a Motion JPEG (MJPEG) codec. Motion JPEG codecs are available from several publishers.
Note: Motion JPEG uses a relatively low level of compression. Low compression can result in slower than usual performance or warning messages about low memory if you work with large Motion JPEG video files in Adobe Premiere Elements. Transcode Motion JPEG files (see Solution 6) to resolve these problems.
If you cannot import or play files from a still-image camera that does not use a special codec for video, transcode the files (see Solution 6). Import the transcoded files.
Ultra-compact tapeless camcorders – including Aiptek, Flip Video and Sanyo Xacti models, and the Kodak Zi6 – record video in various formats. Some ultra-compact tapeless camcorders also use special codecs to encode video.
If you are working with video files from an ultra-compact tapeless camcorder, see the camcorder's documentation. Or, contact its manufacturer for details about the video files that it creates.
If you cannot import or play files from an ultra-compact tapeless camcorder, try installing a codec (see Solution 4). For example, some Flip Video camcorders encode video with a 3ivx codec. If the camcorder doesn't use a special codec, transcode the files using software bundled with the camcorder or by using other software. (See Solution 6). Then, import the transcoded files.
If you are able to import files from an ultra-compact tapeless camcorder, work in a project with appropriate settings (see Solution 1).
Video files that are purchased from online stores, such as the iTunes Music Store, generally include copy protection and digital rights management (DRM). They cannot be used in Adobe Premiere Elements.
