Question

Live Capture and Edit growing files,what external drive is fast enough to use?

Hey,

I'm trying to get a setup working where I'm recording into an AJA IO box from my camera into an external drive that's connected to my computer.  I'm then using those growing files to edit in premiere.  The problem I'm experiencing is I'm dropping a lot of frames in the record.  After troubleshooting, and trying different methods, I believe my external drive just can't keep up with the demand. I'm recording 1080i files into a 6tb G-drive (write 206/read 197). Working on a brand new fully spec'd mac book pro.

This project was kind of thrown in my lap and now I'm trying to take what the company has and fix the solution. (I've looked into softtron movie recorder, which looks awesome, but I don't think the company is ready to spend that kind of money yet. though I pitched it, if this process keeps going).

For now, I'm looking for a better external drive hhd or ssd that can handle the situation.

I'm currently looking at the lacie 2tb bolt 3 thunderbolt 3 external ssd, on b&h it's on sale for $599.  Is this the answer?  or does anyone have any experience with this and can push me in the right direction of the best drive to use?

Any help/guidance is much appreciated!

Mike

somebody here had a thread going about something called NVMe stuff...basically like a flash drive type memory that goes into pci-e slot …

I did some googling on it ( it's new stuff ) and there are real benefits with speed. There are also (unfortunately) issues with heat.

maybe check that out while you're looking around ?

I saw that emmy link.  It was helpful and it's exactly what I'm trying to pull off.

Unfortunately he doesn't get into the storage aspect of it. And I'm trying to work with what I was given. In reality, the AJA IO box is really meant for streaming. I'm using because that is what we have. And it works.  I'm just trying to perfect it. And the one issue I have is the occasional frame drops. Using the Aja system disk test, all the drives I have on hand have failed with red spikes.  That is what led me to believe it is the external drive I'm saving to.

I think I would go ahead and bite the bullet and go for the SSD drives.

Even if defragmenting the hard drive raid 0 improved seek time and read write time, you'd always have to worry about it.

Can't think of anything else that would be a bottleneck … I hope you let us know what happens because I'm anxious to hear solution !

    I always recommend using a self-built desktop with multiple internal drives for editing.  I would maintain that recommendation even for Growing Files.

    Is there any reason normal recording and later transfer to an edit system won't work?

    Thanks Jim for the response.

    This setup is on a laptop. It will travel from location to location, at a 5 building campus and on the road all over the US. I'm looking to build something portable for travel and break down and setup.

    The higher ups want to walk over at the end of a live seminar and have selections and a highlight reel ready to approve and send off. They want to turn clips quick like in a news environment.

    What codec are the files being recorded in?

    I've never edited from growing files with Premiere, the only info I could find after a quick search was:

    Premiere Pro CC supported file formats

    Since you are Mac based, try downloading the FCP-X trial and see if you get the same problem - which will place more focus on the drive as being the bottle neck.
