I just got new graphic card GTX 770 super clocked. I have recorded some videos with new codec (H264 nven). I used bandicam to record. I have recorded in 60 fps and the quality is really good and the size is pretty small. It works great in VLC media player. But when I import it in after effects it doesn't play video, there is just sound... I have tried converting to other formats, but the quality is worse. Any soltions?
AE doesn't support accelerated CoDecs and that is just that. For your quality issues you might want to read up on how to avoid them and get a good conversion by choosing the right transcode settings...
