Upconverting 4:3 Anamorphic Video to 16:9 Video
4:3 anamorphic video is actually a 16:9 image squeezed into a 4:3 frame, so it can easily
be scaled to fit an HD sequence.
480 anamorphic to 1080
480 anamorphic to 720
To edit 16:9 anamorphic footage into a 16:9 sequence
µ
Follow the instructions for scaling a 4:3 clip into a 16:9 sequence in “Pillarboxing 4:3 Video
in a 16:9 Frame.” However, instead of using a normal 4:3 clip, use a 16:9 anamorphic clip.
The 16:9 anamorphic clip is now scaled to fit in the native 16:9 sequence.
Rendering Mixed-Format Sequences
For the highest-quality output, you should always render any segments of a sequence
whose render status bars indicate that they need rendering. When you use the Edit to
Tape and Print to Video commands, Final Cut Pro automatically renders these segments
for you. For more information, see
“About Render Status Bars.”
In some situations, you will need to render nonmatching clips to play back your sequence.
For example, if you add an uncompressed clip or HDV clip to a DV sequence, you may
need to render the clip in the Timeline if your computer cannot play back the source
media in real time.
External Monitoring and Output
To output a sequence to an external video device, the frame rate of both the sequence
and the video device must match. However, the image dimensions and codecs can be
different. Video is properly scaled and letterboxed or pillarboxed to fit within the
dimensions of your output device.
