“I have MC 5.01 seeing mxf files created with my Nanoflash in AMA mode, but upon trying to export via Avid Codec, Avid advises it cannot export Long-GOP without transcoding first. Yet, the files were created in I-frame mode with Nanoflash. I am updating now to 5.03, but does someone know why Avid thinks this stuff is long gop? The big reason for me buying nanoflash was to use mxf with Avid in a way that would avoid that transcoding issue, as that is a major downside to the AF100 avc workflow for me.”
nanoFlash is the world’s smallest, lightest, lowest-power, professional HD/SD recorder/player. The nanoFlash from Convergent Design represents a huge leap forward in tapeless workflows. Easily mounted to your camera, nanoFlash is designed to record higher quality images than the camera itself, by capturing never-compressed video/audio from the HD-SDI or HDMI output. nanoFlash utilizes the very high-quality Sony XDCAM 422 CODEC, recording the video/audio onto affordable and readily available Compact Flash Media, at up to 160Mbps (Long-GOP) or 220 Mbps (I-Frame). The footage can be stored in either Quicktime (MOV), MXF, or MPG file formats, providing near-universal NLE support as well as DVD / Blu-Ray authoring formats.
MXF format is great for record high-definition videos, it can keep the high quality. But, MXF format video is not easy to use because many editing software doesn’t support this format, like Avid Media Composer on Mac.
Part One: Import nanoFlash MXF to Avid Media Composer with download Avid AMA MXF plugin
You will need to be running Avid Media Composer 3.1.1 or better to take advantage of Nano Flash recordings. Ideally you should be running Media Composer 184.108.40.206 or later which is when AMA file link support was introduced (no SD file support with AMA linking). Some pointers to follow
– With Media Composer 3.1.1 you can only import files.
– When using Media Composer you should record i-frame only MXF Files on the Nano Flash.
– MC also supports Long-GOP 50 Mbit but this is more taxing on the system so best avoided.
– 720p 24/25/30 frame rates are supported but only up to 50 Mbps rate.
As with Avid Media Composer can playback (decode) files up to 280Mbps but will render any effects work down to 50Mbps. With the introduction of Avid Media Composer 5.5 you will need to download the Avid AMA MXF plugin from the address below: http://www.avid.com/US/products/Avid-Media-Access/plug-ins
