I'm fairly stumped as to why I'm having severe fps lag after processing when the program worked fine when I used it back in February. I've tried many different codecs, huffYUV, Uncompressed, ffdshow, and I still get the same result. If anyone might be able to help me out I would appreciate it. If it makes any difference, the input is a vga still image sequence. |

How big is your file per second, i.e. megabytes divided by seconds? If that's above about 10MB/sec, you risk being hard disk bottlenecked. Also, your frame size is around 640x480, I take it?

Frame size is around 1280x720 I believe. I'm fine where bottlenecking is concerned. |

With lossless 1280x720 at any normal frame rate you're not fine at all as far as bottlenecking is concerned.

Maybe I'm misunderstanding what bottlenecking means. I thought it was concerning running out of hd space to the point it cuts off the recording or encoding. As I mentioned I was not only trying to use lossless but other codecs as well. |

In this case it doesn't mean you run out of storage, it means to play the file properly the HDD would need to access data faster than it can.
