Transition Rendering & Drop Frame issues

Hello FCP pros
I'm very new to final cut pro but managing to navigate my way fairly well through some basic edits i have to do for my job. I understand there are certain transitions that are bolded which don't need rendering, however; these transitions don't appear bolded in the menu and I always have to render the basic transitions (inc:cross dissolve and fade in fade out) . I have set up my sequence settings to match my source compressor settings (most are either none or using anmiation codec) yet i have to render and render constantly everytime i drop a transition on the timeline or change a transition. Why is this happening?
The second question is I constantly get drop frames when i get either an orange or grey line above the timeline. I have switched from Unltd RT to Safe but it still happens. Commonly I have 3 elements in my timeline that have different aspect ratios and 3 different compressor settings. Is this what

Annimation and None are 4:4:4 codecs that will only play back with a very fast drive array.
If you want to edit in these formats you have to understand that they are not RT enabled (as the uncompressed codecs or DVCPRO codecs are).
So to answer the question in the most basic way, you are using codecs and a color system that is not optimized for use in FCP. You will always have to render a dissolve when editing in annimation or none. In fact, you would not even be able to edit in this color space in and AVID.

On the second part of your post.
FCP requires that you edit in ONE codec only. Every other codec introduced will require rendering to the codec that the sequence is in.
The only time you could get away with multiple resolutions is if you were to use different levels of photo J-peg compression anywhere from 1000-to 10000K, similar to AVID's 20:1 or 2:1 but youcan not put 2:1 together with 1:1

Thanks for this very quick reply David...much appreciated. For future reference (so i can tell the company who are sending me content) what format can i work with where the transitions will be enabled to work in Real Time.

Much of this depends on your set up. You can work with 10 bit uncompressed SD material on a SATA raid, or you can try to push that much data on a G-RAID firewire 800 Drive, but if you are woking off firewire, I would ask for the material in DVCPRO50 format.
There are many variables depending on your configuration but it is definitely an external drive solution.
Remember the single largest factor for RT in FCP is drive speed. The faster the drives the more RT you will have. The processor, the ram, etc factor, but none as much as the speed of your hard drive system. You want a fast FCP system, by the fastest drives you can find.

Hi David;
I have a follow up question to this thread. My company purchased Procoder and i'm now taking video we get from our partners (that is in either Animation, none, or Avid Meridien codec) and using the procoder wizard to convert it to DVCPRO50. I'm wondering if converting has any affect when working with these files in FCP, or does it still come down to how this footage was originally output. Reason i'm asking is i'm still getting some drop frames error messages coming up.
Also i noticed someone posted a question about getting the right set up and Mac to run FCP efficiently. This will be very useful info for me as well as luckily we are submitting our budget for '07 so any hints on what we should try to get would be most helpful

Well yes and no. After begging and pleading we've finally got an external drive (office budgets...what can i cay)Also we don't capture anything here, our client delivers hi-res QT uncompressed on DVD (several sometime). I usually drag these to the desktop and set up a folder on the iMac and store the content there. I'm guessing this is something i shouldn't be doing judging by your post. Luckily I can start using the drive we got last week. Usually what i have been doing is once i've exported a finished edit i usually have to delete the source file off the OS.
Thanks for this heads up, i'll make sure never to store media on the drive.

Hi David
if possible can you reply to my follow up post about converting footage with Animation or Avid Meridien codecs to DVCPRO50. Just want to know if converting at this level has any effect or does it still retain the properties of how footage was originally output

Im using an Imac Core2 Duo 2.33 with 3GIG of Ram and a 500GB Hard drive. While I understand that to get real-time output, I need an external drive, here's my question.
When I output a sequence to a movie file, the movie file has a couple of unrendered frames in it. I don't get it. Prior to outputting the movie, I have used the command D keystroke to render all clips and transitions. Yet when FCP outputs a movie file, not all transitions are fully rendered. If I were trying to output to tape live, I could understand dropped frames, but I'm not.
My background is Premiere and in that program, even if you don't render the timeline, it renders it to the output file. I can't think of a single reason that FCP should give me this result.
