  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Clips crash RedCineX

I am using Mac. I have a bunch of clips that play perfectly on proxies on all resolutions. However, when I load it up into RedCineX the file crashes it. Is it possible to have proxies that play perfectly but have R3D files that are corrupt?
 
Hi David, can you email me? rob at red dot com
 
I am having this exact same issue, I have clips that play through, and I can watch proxies in Quicktime, but as soon as I start scrubbing the clip in RedCine-X it starts crashing the software. I shot a 4k Anamorphic project and have a handful of clips that are doing this. Any ideas?

*EDIT*
I found a specific range of frames that cause the crash consistently. Is this something from the transfer, or just bad files off the camera?

*They are all CF Card reels BTW.

Thanks!

It sounds like a bad transfer off the card.
Any chance you still have the original cards?
 
No, the cards were overwritten several times over the course of the production. We knew there were bad clips from DIT, but only had two 16gb cards and everything was in such a rush, we just had to keep moving. Luckily it's a music video and the clips that are corrupt aren't the end of the world. In fact, i've been checking through the backup drive, and some of the clips are actually fine on that drive. I don't understand how one reel is corrupt on the main drive, but not on the backup drive when they are the EXACT same file size.

So if this is a case of a bad transfer (which is why the card is transfered to each drive individually) what is a good failsafe for DIT other than watching EVERY clip from start to finish on both drives? On quick moving sets this seems nearly impossible. Any tips?

I recommend using disk_arbitrator to mount mags readonly so spotlight and other apple tools aren't writing to the disk.
By mounting read only, in case something accidental happens or there's a bad cable, there's less chance of bad stuff being
written to the mag. It won't cover every case but significantly improves things from my experience.
 
Cool, I found that utility, Disk Arbitrator 0.3.0, I just don't understand how different frames are bad on both transfers, when they are the exact same filesize down to the byte. Is it bad practice to transfer to both drives simultaneously? Also, what do some of you other DITs do to checkt both drives after the transfer if you don't have time to watch through every clip twice, and they both display the same exact filesize?

Last thing, I have one card has two clips, and both are corrupt at different points, so it's clearly a transfer issue (also it crashes redcine and quicktime instead of displaying grey frames). Will Red Undead possibly help me, or are these clips most likely gone, other than trying to trancode around the bad frames?

The clips are most likely gone, especially if you have written back over the cards. 16G CF cards I assume?
Use a program that provides MD5 Checksums and that will help next time, but still need to take the time to proof the footage before the cards are written over.
R3D Data manager is good for checksums. Also Dustin Cross (you can find him on this Forum) wrote a shell script that I use exclusively for copying files and performing checksums.

Good luck

Thanks a bunch! I'm going to get R3D data manager right now, but it seems like the only way to be able to carry out all the responsibilities of a DIT with looks, one-light color adjustments, transcodes, etc, it's necessary to be a two person team. One data wrangler verifying all data while DIT works with cameras, looks and transcodes.

And yes, it was the 16gb cards, on a Lexar FW800 reader.

Thanks guys!
 
Its possible for one person to do it, but you need to scale to the job(s) at hand. On shows Ive been on theres usually more than one person and certainly more than one CPU. R3D Data Manager takes care of a whole slew of small things and will even send you a text message when its done, so you can do the larger things.

Also, only having 2 cards means you are certain to fail at some point. More media means things can be done without so many shortcuts and you can have time to breathe.
 
Great, I'll definitely be buying R3D data manager before our next gig. The last question I have that you brought up is multiple computers. We have a 12-core and 2 MBPs, but I have yet to find or come up with a way to speed up the whole DIT process using more than just one computer. If I have 2 externals and a card reader, I feel like using the second computer to do anything would involve moving drives back and forth between computers. Any tips or links to threads where this is discussed? I'd love to find a way to utilize more than one computer since we usually bring both, but the laptop more or less just sits there for internet, or text documents to take notes, etc.

I thought I might also share, I've been saving many clips so far, luckily due to long takes and the 2.15GB R3D file splitting. I've been finding the bad frames on one drive, and trying to estimate which R3D file those frames would fall in, and coping just that one R3D for that section of the clip from the backup drive (which fortunately had a different corrupted R3D). So far I've salvaged several clips, so if anyone is having these problems, it's a last-resort fix if your clips are broken up into multiple R3Ds.

You can do it right now with an ethernet cable and sharing drives. But you should have the bandwidth on each drive to sustain a read/write at the same time - which most bare drive or simple raids cant do. Thats where you'll start spending money - where multiple drive RAIDs with high I/O come in handy.

We had the same problem, and the Lexar appeared to be the source. It would tend to overheat and start corrupting files. I actually got better results just using a Sandisk USB reader, although obviously at slower transfer speeds.

If you have more than one Lexar, try switching on each transfer to keep temperature down.

We got the RED CF card reader and that's been rock solid since.

R3D is a must for whichever way you go.

I upgraded to the SSD drive. Haven't encountered a problem since. Worries are gone and sleep quality is much better.
