Digital Web heeft review gepost van de Matrox Marvel G400 TV, een video-editing kaart met 16Mb geheugen en hardwarematige MJPEG codec:

You can attach a TV to the break-out box by using the s-video and composite video outputs but not another monitor as with regular G400. You can also connect a digital Flat Panel as the secondary display. Support for digital Flat Panel available as a separate upgrade module which means occupied PCI slot. Marvel G400 has on-board Zoran ZR36060PQC chip designed to support a hardware MJPEG encoder for true to source video capture. The advantage of the hardware MJPEG codec on the Marvel G400 is that capturing at full D1 (704 x 480 (NTSC) at ~30 fps (29.9 fps)) resolution can be done without dropping any frames due to the inability of your CPU to keep up with the capture. ATI All-in-Wonder 128 and the 3dfx Voodoo3 3500TV, which perform solely software MPEG2 video captures are CPU dependent . Using a software MPEG2 codec to capture video causes the entire workload to be placed onto your CPU and any processes running in the background while this capture is taking place will contribute to dropped frames. If you look at ATI's All-in-Wonder 128, which only does MPEG2 video capture in software, one of the requirements for capturing MPEG2 at 640 x 480 at 30fps is that you must have a Pentium III processor. The Marvel G400, with its hardware MJPEG, describes the minimum system requirements as a 233MHz AGP enabled system.
