  • 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 :)

For those who shoot or owned EPIC right now. What is the nature of R3D file size as compare to RED R3D ?

Assuming 16GB in RED will gives you duration from 7-8 minutes worth of footage, what about EPIC ?
 
If i look at the list, the file size is about twice from RED

Assuming default setting 8minutes will cost you 24GB, that is a new realm from RED that we have to deal with. I dont think people is willing to go any lower than the default setting. Thanks for the share

Appreciate it very much

Its very big, shooting 3D is enormous. The realm of Laptops on set is now thankfully over. E-sata isnt even fast enough anymore. I've been using H380 connected to Redmag reader. Going to my 16TB RAID takes about 9 minutes per card. 20 minutes to a single drive on E-sata.
 
It looks like about 12:1 will give you RED One style numbers which I believe I've heard Vincent Laforet is using. If you also take into account that you can get data off the 1.8" RED MAGS faster than off the old RED DRIVES, those used to the RED ONE should be fine until you go into high speed and HDRx. It seems that if productions want to really take advantage of EPIC, we need to up our game on the data handling side of things (which I'm currently in the middle of doing).
 
I've stuck with 5:1 shooting 24 & 30. Very nice compression. About 25 minutes on a 128Gb card. I did some 3:1 on a green screen with cats, Hair was keyed quite nicely.. with some basic tools in AE/
 
Hi Alex

It's nice to have those RAID on set but unfortunately that will limit certain projects that simply wont allow you to have such luxury. I am still believe macbook pro is still needed on set, but this come with its own downside.

Which is much longer download & encoding time (without red rocket). So a lot of this adds up to consideration for EPIC workflow and what we should do on set. Storage seems to be getting smaller and smaller.

I still dont understand the quality that we will get from different compression ratio. I hope EPIC-M owners will shed some light into this before the EPIC-X customer. What makes you think that certain compression is good. If 5:1 is ok, why should we go to 3:1 or the other way around completely eg 12:1

RC42 is comparable to 7.5:1 compression on the Epic.

I forget the comparison to RC28/36 but shooting around 7:1 and going to 5:1 when needed is our general workflow and we've been very happy with it.

I just did a 3D job, Single Epic Rig. 1.6 TB per day. I refuse to work without a Tower on Epic jobs, I don't want to be that guy who said a laptop is okay.
 
Rivai where are you man, I tried to call you, no luck, are you in Malaysia?
 
I agree with Alex 100% Just finished an Epic 3D shoot too. We averaged 1.6TB per day and our biggest day was 4TB. Try sticking that though a Macbook Pro and you're asking for problems.
 
Guys..thx for the info. I'm glad to start this thread. I have begin to see what we are dealing with this time. This sounds like dealing with ARRI RAW file size, despite the resolution is lower in arri. But there u go...

We still need a mobile solution..if we always need tower to be used all the time..I don't think it will work.

Panos..how are you ? Its been a busy month and pretty much spend time flying to different location. Will be free next month..let's do some catch up later on. :)

easily less than half the data rate of arri raw even at RC 5:1
 
I just received my EPIC M a couple of days ago and I am in the same dilemma.. What compression to shoot at? I want to shoot at the highest compression without too much loss, so any thoughts on this?

Obviously if you are shooting surfing, car racing or high energy vision you would shoot at the lowest compression, but for everyday drama what are people shooting at?

RC 5:1 is a good high quality starting point. Many big budget features used 5:1 (ie. spiderman).
RC 6:1 and 7:1 good alternates if you need to be more prudent about data throughput.
RC 8:1 even more so.
I'd reserve RC9:1 thru RC12:1 for high speed shots where you don't have the flexibility to go lower.

That's true. But the point is we are dealing with something different now. As EPIC-M owners stated that macbook pro is not fast enough on USB, Firewire 400 or 800. The data storage must be huge. It is beyond than RED realm now

This is also come into question. Even we have our RAID on set, but that it still takes time to transfer to normal HDD for client usage.

I would prefer if you can give suggestion to the above concern.

It is not about RED vs ARRI file size.

One more question for EPIC-M owners. Does shooting in 5K giving you wider POV ? I assume so..but please correct me if i am wrong

or HDRx shoot where you have to be carefull about data flow.

I've mainly used 6 (for high iso shoot) 8 for normal shooting without HDRx and 10 for HDRx shoot.

Low budget film.

It would be awsome to test those compression ratio to have a more technical point of view on limitations of these compression.
