Hi Keith,
It could be that you are now exceeding the color depth of the format, basically causing color clipping. For H.264, that would mean increasing the level / profile in your export settings.

Well, it came up recently in a previous post. It looks like Premiere now blends no matter what… Maybe be Todd could chime in on that.
Do double check that frame blending in unchecked when right clicking on the clip.
You’ll have to interpret and export in After Effects instead.

Eric,
An easier way could be to simply interpret and export as 24p, the difference in speed and audio likely won’t be noticed.

[Tom Durham] “Thanks Vince. So you “no” means: No it will not go to h264 before going to my export codec. Right?”
That’s correct.
[Tom Durham] “So you get 64-bit performance out of cineform on a mac? that would be awesome.”
Well, I assumed you had tested that theory 🙂
[Tom Durham] “Yes, I’ve actually encouraged our shop to start the transition to windows. Any other advantages of switching over that might be good ammo in a budget discussion?”
I found Windows 7 on Mac hardware very stable, and I constantly go back and forth depending on my needs. I find Premiere on Win 7 much snappier than on OSX (again, personal experience, and I only used the trial version on the OSX side). The obvious advantage is the use of extra formats, the disadvantage is the loss of Prores access.
Another disadvantage is with people handing you Mac formatted drives. Macdrive performs pretty well, but I’ve encountered issues here and there. Again, that’s why bootcamp is so wonderful…

[Tom Durham] “Question: Let’s say my timeline is h264, with lots of effects and stuff. My export is DNxHD or something similar. I’m assuming it will NOT render to h264, THEN transcode to DNxHD when I export–but go right from the source files, through the effects engine and right to the new codec. Correct? Probably obvious but just making sure.”
No, although you can choose to use “previews” to accelerate the export (say for client review) by checking “use previews” in your export settings.
[Tom Durham] “Question: Thanks to geniuses on the Cow, I’m understanding that anything that needs QT cannot take advantage of Premiere 64-bit goodness. On a mac, I’m having a hard time finding any 10- or 12-bit codec that supports alpha, that doesn’t require QT. ProRes, DNxHD both seem to exist in QT wrappers. Does Cineform? Any other suggestions?”
Yes, Cineform supports Apha channels. That’s the only thing I can think of. There’s always bootcamp 🙂

Hi Eric,
Pasting from my post below with some additional personal experience.
Your best options are Twixtor or a plugin from Video Copilot (free but very render intensive).
Twixtor will do very well in many cases. The downside (other than having to buy it), is that you may see artifacts in some instances. For example, I noticed that shots made in front of LCD screens (like a finger on a phone, or a hand in front of a TV) will have a smudge around them. The software can also have problem creating frames from low shutter shots. Overall, the conversion looked beautiful.
Video copilot uses a similar technique, but the render times were sometimes unbearable… On the upside, it’s still free.
Cheers,

Ben,
Indeed you can mix, but the result, to my eyes at least, will be pretty bad in most cases, the more motion, the worst it gets. Your best options are Twixtor or a plugin from Video Copilot (free but very render intensive).

Hi Justin,
My guess is your problem is the limiter. Easy to figure out, turn it of and do a short test export to Mpeg2 DVD and listen to the wav file.
I never use the Premiere hard limiter, the compressor (part of dynamics plugin) is a much better option.

Hi Yossi,
That’s going to be a really hard question to answer, especially without knowing what you already have. Upgrading your RAM could be a good thing, however, you have a slow drive, an old CPU, graphics card, or motherboard, they then become the bottle neck in your system.
