Final cut pro and af100 problem

I have problem when I transfer the footage from camera into fcp7. It basically has artifacts that flicker through the picture at certain points and has like a clipping issue.

I'm transferring the footage via "log and transfer". Do I need to set a special setting in fcp7 as when displaying the picture directly from camera onto 65" HDTV no problems. Also tried different cards and they have the same issue.

Any tips would be appreciated as I'm online at this and I know I must have a setting wrong somewhere
 
Matt make sure you are converting to ProRes422 or Proxy like the the Porcupine Sweed says.

You can change the codec settings in Log and Transfer, it is one of the tabs.
 
Ive done as suggested and it seems to transfer ok. Only issue that happens when i start to edit it comes up with a "Dropped Frames Error". Anyone know know what Im doing wrong???
 
This thread would probably be better off in the FCP forum, but...

On the FCP log an transfer window theres a cog, when you click on it a dropdown appears and you'll see preferences. What is this set to?

What mac are you using? How much RAM? Are you doing anything in the background? Whats your HDD size and how much free space is there?
 
I get this dropped frames error. I'm on a dual core 17" macbook Pro with 4 GB of ram and i'm editing off a 1TB firewire 800 external hard drive
 
david! yes, Perian! i am not familiar with this, FCP crashes everytime i log and transfer a long interval frame rate clip and it says due to Perian. thanks!

oddly enough, i do feel like my clips look better in the log and transfer viewer than when transcoded to proresHQ and in the timeline.
 
The timeline always shows a proxy of the original. Render it and view the export.

Matt,

I am having the same issue with the AF100 and FCP - artifacts on my footage after Transfer - and I have the correct codec settings in Log and Transfer (I end up with a ProRes 422 file). The footage is fine before Transfer - so it is FCP that is adding the intermittent glitches.

The pull-down menu in the Log and Transfer window only allows for various iterations of the ProRes codec, plus the Apple Intermediate Codec. My clip is an hour and 40 minutes long (multicam performance), so doing an output test takes forever. Should I re-encode with the Apple Intermediate codec?

Anyone have suggestions?
 
What version of FCP are you using?

Try locating the post-transfer files in the Finder. (Use Reveal In Finder in FCP) Quit FCP, and try playing the file back in QT Pro. You may find that the glitches are part of FCP's playback, not baked into the video file.

HTH.

I am using FCP 7.0.3

The file is corrupted in the encode process. The glitches are "baked" into the video file.

The original media (pre-Transfer) is flawless.
 
I had the exact same problem. Here is what I discovered and how I fixed it!

I would only see the glitches when i was impatient and began to playback the clips that had just been transcoded.

The first clip ingested never had the issue. All other clips that were ingested (while I was previewing the previously transcoded files) had glitches at some point.

This I believe is caused by a taxing of the I/O operations of the drive that FCP using for it's scratch disc.

I no longer have these glitches: Reason? I have completely stopped "previewing footage" while the L&T window is actively working on ingesting.

I was transcoding to ProRes 422 LT.

I don't preview the footage - I set it and go. But my clip was loooooong, and the little external hard drive (500Gb iomega blackbelt USB 2.0) must have had issues. It performs like a champ while cutting, but maybe failed repeatedly during encode. I have the original camera media on a lacie 500Gb firewire 800 drive.

I'll try another encode session of that clip and record directly to the internal drive on the computer - that would be the fastest drive, I suppose. I will write back with my conclusions.

thanks for your suggestions!
 
I'd try to export that clip to the FW800 drive, not the internal drive. Also try using compressor instead of FCP to transcode, I have always had better luck with compressor, Log and Transfer always has its own little quarks to work around in my experiences.

This workflow is materially incorrect.

A USB2 drive will never be fast enough for pro res footage. Nor should you use your boot drive to capture and store media.

To work properly, buy a quality fast 7200 rpm firewire 800 drive and enclosure.

Your media is critical. Use the best quality fast firewire drive to store and edit it.

Never a USB2 drive and never your boot drive.

Do the math on throughput for pro res and the transfer speed of a USB2.

Understand as well how USB2 transfers footage in comparison to firewire.
