The CS2 Premiere Pro Will Not Open an MP4by Alan Donahue
Adobe Premiere CS2 has the capabilities to open and edit all types of media files, including MPEG, AVI, WMV and MOV files. At the time of CS2's release, the MP4 format wasn't as popular or widely used, so the software may not properly import the file. Updating your computer's codecs, file types used to process video formats, will make the files compatible with Adobe Premiere Pro CS2. You can find codecs for all types of video and audio formats.
Before you update the codecs, use the current settings to get the video working. Open Adobe Premiere Pro CS2 and start a new project. On the setup screen, select the video profile for "Xvid" videos. The video should open in any video setup, but this one specifically caters to MP4 files. Right-click the "Project" window and select "Import." Check the lower right area of the screen for the "Conforming Audio" box. Don't do anything else to the project until the conforming has completed.
Exit out of Adobe Premiere and any other media programs before you download and install the codec pack. Choose from among several free video codecs for download. The K-Lite Mega Codec Pack, a free download, includes the MP4 codec and multiple variations of it, including MKV and OGM. XviD and DivX codec packs are also available for free. Download the codec set of your choice and follow the installation instructions. Restart your computer once the download is completed.
Adobe Premiere Update
Along with the codec installation, an update to your Adobe Premiere CS2 software could help increase compatibility with MP4 files. While in Adobe Premiere, click the "Help" menu and select "Updates." The software will contact the Adobe Premiere website and download any updates to the system or video compatibility.
MP4 File Playing
Even when the MP4 files open, they'll most likely operate slowly and could have visual glitches. Use Adobe Premiere CS2 to convert the file before you edit it. Drag and drop the file into the "Video 1" slot. Go to "File," "Export" and select "Video." Select the "AVI" file option and press "OK." Once it converts, use it in the software to edit as you need.
