real time not full quality
I noticed in a recent edit that some 16:9 footage I was using in a 4:3 composition (scaled using the motion tab) was looking a little under par. The sequence quality bars told me the shot did not need rendering as it was capable of being played full quality in real time. However, worried about the quality I decided to force render the clip. Voila! The quality improved. This worried me quite a lot as it suggests FCP may be playing out other shots in real time, possibly with filters like colour correction, supposedly in full quality, but actually not. I now force render every shot in my timeline before mastering to tape. Should this be necessary? Have I inadvertently mastered low quality shots in the past because FCP did not think they needed rendering, when in fact they did?

If you see the DARK GREEN bar, you are not at full quality. Only the rendered purple, or plain grey means full quality. And besides that, the image you see on the computer displays is not full quality either. It is a low res proxie so that you can play back the footage without dropping frames.

Absolutely. You should ALWAYS fully render before you output to tape. A lot of what FCP does is in RT, but not full quality so that you can spend time editing and not rendering. When you are done editing, hit render, grab a cup of coffee and relax, then come back and output. Or take a quick restroom break…depending on how fast the render takes.

Hi Ken,
When exporting a self-contained movie, all the footage that has undergo any change is rendered even if FC is able to play it in RT.
I think that trash all the render files before exporting is a good policy (I know some times is not possible for a question of time). There are effects that if you stop the rendering and you re take it later, the continuation will be wrong. This happens with effects where the information of few frames is processed together, for example Movement Blur.Mac OX 10.5.2-FC 6.02-QT 7.4.1

Thanks for these two posts – reassuring to know FCP will auto render even real time playback clips on edit to tape (where they have been modified in any way). Good tip about deleting render files. As an extra precaution I’ve taken to exporting and then re-importing the single render to FCP for playout.
Cheers,
Ken.

This I’ve done few times too. Save the render files in other place and reimport them to FC as any other clip. Like that you don’t loose them.
