When exporting, smart rendering can be used for certain formats to create better quality output by avoiding recompression when possible. Smart rendering works only if the source codec, size, frame rate, and bit rate match the export settings. Supported formats for smart rendering are:
- AVC-Intra in MXF (Format > MXF OP1a & Format > AS-11)
- DNxHD & DNxHR in MXF (Format > DNxHR / DNxHD MXF OP1a)
- DNxHD MXF OP-Atom to DNxHD MXF OP1a
- JPEG 2000 (only works when using the 12-bit PQ space)
- MXF OP-Atom AVC Intra to MXF OP1a AVC-Intra
- MXF OP1a to DNxHD MXF OP1a
- XDCAM HD (Format > MXF OP1a & Format > AS-10)
- XDCAM EX (Format > MXF OP1a)
- XAVC-Intra in MXF (Format > MXF OP1a)
Note:
To activate smart rendering for codecs in an MXF wrapper, check the “Enable smart rendering codec” option found under the Video settings tab of the preset.
- Animation
- DNxHD
- GoPro CineForm
- NONE: Uncompressed RBG 8-bit
- ProRes 422
- ProRes 422 (HQ)
- ProRes 422 (LT)
- ProRes 422 (Proxy)
- ProRes 4444
Note:
Smart rendering for QuickTime codecs is automatically enabled any time the source settings match the export settings.
QuickTime Match Source (Rewrap) is only supported for several compatible video streams. These include most combinations of the following QuickTime codecs:
- Animation
- Apple ProRes (422 & 4444 flavors)
- DV (25, 50 & DVCPROHD)
- GoPro CineForm
- None.
Note that if your source clips are not one of these codecs, then QuickTime Match Source (Rewrap) is not supported and displays a warning.
QuickTime Match Source (Rewrap) is only supported for a number of compatible video streams. These are basically the codecs that are supported for Smart Render. These would include most combinations of the following QuickTime codecs: Animation, Apple ProRes (422 & 4444 flavors), DV (25, 50 & DVCPROHD), GoPro CineForm and None. If your source clips are not one of these codecs, then QuickTime Match Source (Rewrap) is not supported and will provide the warning you mentioned.
- DV/DVCPRO/DVCPRO HD
- MXF OP1a AVC-Intra to QuickTime AVC-Intra
- QuickTime XDCAM to MXF OP1a XDCAM
- QuickTime XDCAM HD to MXF OP1a XDCAM HD
- QuickTime AVC-Intra to MXF OP1a AVC-Intra
Note:
- DV, DVCPRO, and DVCPRO HD formats smart render whether they are in a QuickTime wrapper, MXF wrapper, or go between two different wrappers.
- To smart render to/from QT AVC-Intra, install the QT AVC-Intra codec.
- The format in which you are smart rendering determines the option to smart render in these special cases. For example, if you are smart rendering to an MXF OP1a format, you must enable the smart rendering check box. An exception is smart rendering DV/DVCPRO/DVCPROHD is always enabled regardless of the wrapper you are exporting to.
