 Video Memory Issue

This problem is usually caused by video cards with buggy drivers that report more video RAM available to VirtualDJ than what is really available (I.e: That onboard the card + your system memory.) VirtualDJ tries to use this RAM for caching the video in memory, so you can jump to cue points, another position in the video, scratch, etc.

As the song progresses, the memory usage will go up accordingly. When you load a new song on the deck, the memory will be freed up and will then start to increase again.

The only solution to this problem is updated drivers/firmware/BIOS from the manufacturer of your computer that corrects this problem. In some cases, older drivers may also fix the problem (Due to be written before when the bug was introduced.)

This problem most commonly occurs with recent ATI video cards, but can also occur with other models with similar driver issues.

To work around this issue, you can try using the Registry Tool to adjust the maximum video memory that VirtualDJ can use (VideoMemMaxUse) to a more suitable setting, e.g: half of your Video RAM (for example, if you have a video card with 256MB of dedicated Video RAM, use a value of 128)

Also, try using the registry tool to toggle the options VideoYV12Bug and nVidiaFreezeBug.

You can do tests with the FPS video plugin available HERE

NOTE: For best performance, a video card that has dedicated video memory is strongly recommended (E.g: Video card designed for gaming.) Basic video cards that share memory from the system (E.g: Intel built into the motherboard chipset) may not give good performance for video mixing.
