Export MPEG-2 using Compressor
When I attempt to export MPEG-2 directly from FCP (Export using Compressor), the encode takes forever. The beachball was coming up every five seconds or so. This is with an UC-8bit 29.97 SD project of about 7 minutes in length. Export setting is Apple Best Quality 90 min (2-pass VBR, everything at default settings).
Any idea why the slowdown on the direct export method? As a workaround, exporting a QT movie with DVDSP markers, self-contained and then compressing outside of FCP in Compressor is very quick. Thx.

Pretty sure you don’t have FCP 5.2.1 or am I that behind?

Thanks for the proofreading.

The slowdown is because all effects re-render directly to MPEG2 (and not the codec of the timeline). This can make for a cleaner encode (but in many cases the effect is not really noticable), but it takes much much longer.
I usually go the reference movie route.

John,
OK. That makes perfect sense. So, if there were a few big renders near the beginning of the program, I’d see a huge estimated time for the encode and I could expect that to ramp down if fewer renders followed. Thank you.
