Dropped frames on playback
on Sep 9, 2009 at 6:31:01 pm

Just loaded Studio 2 onto a new MBP, 3.06, 500GB/7200. Lacie D2 Quadra/7200 RPM/1TB pretty much empty. Still get dropped frame errors on playback of two video streams unless I render the timeline.

O/S is 10.6

Thanks.

What is the format of the footage you are working with? HDV? uncompressed HD? What?

DV. Sorry for not mentioning that.

How is the LaCie formatted? Did you format it after you bought it, or just plug in and play?

Good question. I think it was plug and play. Also, I have a DV deck chained via FW400 into the back of it.

Then it might be FAT32...not good for editing. Needs to be MacOS Extended. NOT Journaled.

Shane, it is Mac OS Extended (journaled). I'm fairly new to Mac, so I'm not sure what that delineation means. How do I go about changing that?

Thanks.

MAC OS EXTENDED is fine...that is what it should be.

Hmm....

What else....

#12 Dropped frames on capture/playback

Shane's Stock Answer #12: Dropped frames on capture/playback

http://docs.info.apple.com/article.html?artnum=58640

1) Do not capture to your main system drive. Since it is busy reading the operating system and application files, it will intermittently drop frames during capture. Capture to a separate internal drive, or external hard drive (firewire and eSATA for example).

2) Deactivate any anti-virus/filesaver software, including Norton and Virex. For some reason these programs think that the large files created when you capture media are in fact caused by some sort of virus, and they try to prevent this.

3) Check the format of the drive you are capturing to. It should be Mac OS Extended, journaling off. If it isn't, copy your files from it and re-initialize it. If it is any other format, you will encounter problems. If not at first, then eventually.

4) Trash the FCP preference files. Use FCP Rescue available here:
http://www.fcprescue.com

5) Make sure that the hard drives you are capturing to are fast enough to handle the footage being captured to it. A regular firewire 400 drive cannot capture uncompressed HD, or even uncompressed standard definition. A RAID array of drives might be in order for these formats.

Just reinitialized with Journaling OFF. We'll see how it goes. Would the FW400/HVRM25 chained to the back end of the drive effect performance?

Quite possibly. Test playback performance without the deck attached.
