Here is his question translated:
I have some AVI videos of small size, perfectly reproduced with e.g. VLC.
Its properties include video and audio data.
Video 00:00:45 of 640 x 480 at 30 fps and audio 88 kbps Mono to rate of 22 kHz.
When I incorporate it in the library to edit it, plays without AUDIO and its characteristics only contains data file and video and no audio.
I also creates the folder where is located two files with the same name as the video of 22 KB *. A.index and * *.index that even if you delete them always creates the me when I locate them from the Studio.
I'm going with the PS19 Ultimate that I've applied the patch (last the 19.1.3).
My computer with W7 Professional, is a Core I7 and so far had not occurred I. Before these videos were edited correctly with previous versions (PS15) but now I don't have them installed.
Any ideas on the problem.
