Hi, importing h264 and mov videos to after effects and in the composition window, I can see them normally. When I try to render, all frames are green. I have tried rendering jpeg sequence, h264, I even tried aftercodecs but rendered videos and sequences are always green since the 2021 update. I have alpha particles on top of the video and they are correctly rendered. In 2020 I had no problem. This is probably a codec problem but anyone else has the same issue or any solution?
Thank you Mylenium but I think it has to do with the naming of the files in the end. I've updated graphics card to the latest version and tried both with Mercury Software and Cuda but the problem persisted. When I changed the naming of the file it no longer appeared green. For instance, I changed the name of the file from "stock-potter-decorating-clay-pot-with-painting-man-painting-clay-bowl-in-pottery-workshop_scpvtcocv_1080__D" to "HH" and it was no longer green. Somehow this version of AE can't read long names or some characters in it. The previous version could. Same with "stock-farmer-holding-grains-in-his-hands-male-cupped-hands-pouring-whole-wheat-grain-kernels-wheat-in-a-hand-good-harvest-harvest-close-up-of-farmers-hands-holding-wheat-grains_s0yzkz8vn_2160__D".
Update: The file renaming was not a solution after all. The problem still exists. But I found a workaround. For anyone experiencing the same issue, I can recommend changing the video's file extension from mp4 to mpg. Thanks to this person pointing it out: https://www.youtube.com/watch?v=pc9XKejA5zo Then AE imports the file normally.
