I have encountered many problems in running Pr with poor machines, but I have never encountered such problems with good machines. Tell me my solution: 1. Is the export sequence a preview sequence? The name of the sequence can be seen on the timeline. Please make sure that the exported sequence is the one you want. 2. Is the frame rate of the material video consistent? That is, how many frames per second should be consistent. If you want to insert or fly frames because of inconsistency, there will be many puzzling problems. 3. Drive C (double document &; Is there enough room for setup? Pr is a big guy, not a work disk. At the beginning of rendering (not when Pr is turned off at the beginning), this disk should have more than 4G space. 4.4 Is there a problem? Codec? It's best not to install players such as Storm Video and Qian Qian Listening to Songs. Sometimes the decoder may affect the normal coding. 5. Is it the official version? Some Chinese patches are flawed, so it is a good habit to stick to the English version.
