Updating flip video files
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.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.***** 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. Codecs are algorithms for compressing video and audio data. For example, an AVI file can be encoded with the DV codec, a commercial codec (such as Div X), a Motion JPEG codec, among others.(Camcorders that record to mini DV tapes use the DV codec.Or, it could be that multiple codecs are installed for the same video format. 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).
Sometimes a mismatch between an imported file and the settings for the Adobe Premiere Elements project in which you are working causes playback problems.
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.
Codecs are available from codec publishers' websites.
Only download codecs from established, verifiable software publishers. Installing a new codec typically causes some video or audio files to become unreadable. 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.
Knowing basic information about an imported file helps you choose appropriate project settings.
