It's all in AVI format Why can't some new VCDs be played and some can? Do you have any parameter settings?

Because AVI video also has different combination methods, that is, coding methods, such as MPEG-4, MJPEG, AVC, VC- 1, while VCD, DVD, EVD and so on. It is limited to reading AVI videos composed of one or two encodings, and usually only AVI videos composed of MPEG-4 can be read. The configuration of the format factory software lists the types of these encoding methods to choose from. Moreover, in the advanced function, you can use the "Multimedia File Information" function to view the information of various media files. You can try to use this function to see what encoded AVI video your VCD can play and what encoded AVI video you can't play, and then turn all the videos that can't be played into videos that can be played.
