Of course, this makes sense. In some strange way, I think this is what I was attempting to say (I know, liar liar...) Anyway, I ran a test raw recording of about a minute, and the max settings I was able to record uninterrupted was something like 1600x800 with an aspect ratio of 2.5:1. I need to get back later and do more of these and jot down my results so I can zero in on the best choice.

This SD card claims to do 90MB/s, but I'm clearly not even sniffing that. Is the card the issue, or is my camera just topping out at 37MB/s do you think?

Ok, I loaded the 10-12 bit ML experiment, but sadly it did nothing to increase write speeds. Is there a setting somewhere that needs to be engaged first? Sorry to hog this thread.
#3
Guys, please disregard my last. The models are hidden in plain sight right in the zip filenames, sorry. Thanks.

Ok, I just updated ML to the latest build, hoping it would yield better write speeds, but they're almost exactly the same as before. I'm very curious about this 10 and 12-bit raw recording to see if I can up the write speed, but the "Experiments" page isn't very clear about which file I need for my camera. Can someone advise? Thanks.

Ok, finally got this test run, and my card results are:

Write speed: 37.8MB/s (1st pass)
                   36.9MB/s (2nd pass)
Read speed: 37.4MB/s (1st pass)
                   37.4MB/s (2nd pass)

Is it time for a faster card???

Ah, I thought it did. I was told to never use less than Class 10, as it met minimum speed requirements. Anyway, my quest to unravel all this RAW stuff continues. Is it possible that the t5i just doesn't take advantage of ML the way other DSLR's do?? Just a thought...
#7
Thanks. I'm using a 32GB Class 10 SD card now. As far as the res goes, I believe my experiments are shooting 14-bit raw. I'll give the 12-bit a try and see how high I can notch the res.

Raw Video / What hardware are you guys writing to?
March 19, 2017, 11:20:54 PM
Since shooting RAW footage gobbles up so much data in such a short amount of time, I must ask exactly what hardware are you recording to? I suppose this should be skewed toward users of the t5i like myself, but are you just using multiple SD cards with ML installed on them? I shot about 30 seconds of RAW at my max res (which was only something like 1280x544...it wouldn't shoot higher than that without stopping after about 10 seconds) and that ate up over 1GB of card space. I'm going to be popping that card out in no time, so are you guys just keeping a massive stash of SD cards on hand for shoots? Thanks a lot.

Guys, my apologies for resurrecting this old thread, but it's tuned in to something I'm trying to discover.

All of this discussion is pertaining to maximizing write speed to the SD card. What happens if I bypass the SD card and just stream live HDMI out to an external recorder that's fast enough to handle all the data? Is this not optimal? I know the external recorders are more expensive, but if you're looking to record RAW video, you're going to need to buy a lot of SD cards. Why not just use an external recorder?

General Help Q&A / t5i/700d hdmi RAW output format
December 12, 2016, 07:13:18 PM
I've been digging around for info on this specifically, but the newest stuff I've found is over a year old so I figured it might be ok to ask some basic questions.

For the 700D, what is the max live stream ML output size? I've read that I won't get better than 720p (which honestly is fine by me) Has the 700D improved in this area and can maybe now handle 1080p?

Is the RAW video output really 14-bit? This will gobble up an SD card in no time. Is the Atomos Ninja a good solution (I know they make a lot of different ones, but since Atomos isn't officially endorsing the 700D as a supported camera (no doubt due to the ML hack), I'm curious to know which flavor of Ninja would be best.

I'll keep searching for an up to date thread on this in the meantime, thanks.

General Help Q&A / Re: Can't find RAW option anywhere
December 11, 2016, 04:48:48 PM
Thanks. My screen is all dimmed out so I couldn't see that, but I've got it now. I saw a video where the option was in the "Movie" tab, which explains my struggle.

General Help Q&A / Can't find RAW option anywhere
December 10, 2016, 02:07:47 PM
I posted this earlier in another forum, but it seems more appropriate here. I'm running firmware 1.1.4 on my t5i. I downloaded ML, and I cannot seem to locate where I can set it to shoot RAW video. Everything I've read says it should be there. I can see the option to vary the H264 bitrate, but nothing about RAW. Ideas? Thanks.
