1DX II cfast write speeds for 4K

[Jack Douglas]

Well, I did manage to fill the card with 4K60, close to an half hour. I'm quite surprised and wondering if that's going to be hit and miss. Could these cards have different speeds due to a greater tolerance in manufacturing and sometimes be OK? The supplier said it wouldn't work.

As I said I have no experience and although I have Corel Video Studio X9, I haven't learned how to use it or even if it is up to the job. My first attempt to import the 1DX2 .mov file is failing, as if it doesn't recognize .mov. Should I record in an alternate format? Anyone willing to guide me just a bit to get started?

That is great news that the Transcend can do 4k60p, in theory it is possible since to do 4k60p you only need 100MB/s and that card is rated higher than that. I had also seen some mixed reviews stating it could or couldn't do 4k60p so it is good to hear your experience. You might find that after using the card a while it will stop being able to fill with 4k60p when this happens performing a low level format of the card will normally sort this out.

As for the choppy playback that could be an issue with either your player (or PC hardware) or the actual video itself (the fact that it works on the camera steers me to it being your player). 4k60p can be very taxing to playback on a PC and some players don't handle it at all. I have had good results with Media Player Classic Home Cinema as well as VLC player.

In terms of editing I unfortunately don't know anything about Corel Video Studio X9, it does look like that is not the latest version of the software so you might need to upgrade to the latest version to open the files.

If you continue to have problems with it (unfortunately if I remember correctly you can't change the format of the files coming out of the camera) I can highly recommend Davinci Resolve 14 (the free version is very good to get started with video editing and grading). Initially version 14 didn't work with my 4k60p files but a subsequent update fixed it and it now works.

Editing 4k60p on my machine is smooth without any issues.
My PC specs are as follows:
Intel i7 5820k 6 core 12 thread CPU
32GB memory
Nvidia GTX 680 (this is currently my bottleneck and I intend on upgrading soon).
512GB ssd (OS Drive)
256GB NVME SSD (I use this as a sort of scratch drive since it is crazy fast)

Gareth, thank you ever so much for this. My feeling, after reading more last night is that you are absolutely right about everything. It's starting to sink in.

My good but 10 year old PC is no longer up to the task with its 6 GB of Ram etc. Nothing in my house can handle 4K viewing so really why am I shooting it. I guess the answer is that it gives flexibility and options if in due course I have something worthy of further editing, for example when I head back to that wonderful little island of Haida Gwaii. So, I'm sure I need to persevere and learn the basics.

Can you or anyone else recommend a good resource or book that would soften the pain of learning all this ASAP.

I would suggest that you don't shoot 4K. It is a beast to store long term, even short little clips. My computer is new and is quite fast but even it has problems playing 4k60. If you have the adobe CC, you can download Premier and use that to edit. You can easily work with 4K files and go frame by frame to grab/export stills.

With our camera you can only shoot .mov with 4k. And if you are wanting to take frame grabs, you wouldn't want to shoot at the lower quality mp4 that it records anyways. Since you can take frame grabs right from the camera, so you shouldn't even need software.

If you are just interested in making home movies, I would again not suggest using 4k. It takes a good editor and time to learn that editor. HD is great. As we talked about on other threads, don't listen to all the forum dwellers mocking Canon's lack of 4k as being such a big deal.

 

[ethanz]

I'm pretty insecure in what I'm doing but my thought was it's cheap enough that even for stills it's decent value. Presently Ary Tv Dramas
I have only the Canon gift 64GB Cfast and a friends gift of a 8GB CF (all mine were SD). The seller states that it won't do 4k60 which I accept. Any comment appreciated?

You've lost me on this post??

Komputerbay has been around for a while (at least for being an electronics company). I bought computer memory from them like 10 years ago.

 

[Jack Douglas]

ethanz, thanks for the comments. Did I somehow contribute to that bot?

My thought about 4K is that I would be doing short clips, mainly of wildlife, primarily birds and would like the ability to assemble a short movie that allowed me to crop or zoom in etc. so wouldn't it make sense to record in 4K. However, what about 60 vs 30??

I wish I could get my hands on a good resource to study.

BTW I glanced through the manual and didn't see how to grab frames in camera. It must be in there then. Too much on the go at one time seems to be my present problem.

Jack

 

[ethanz]

Except in a previous post you said you got 20 minutes of 4k60 chasing birds, which if I am correct is at least 100GB! A couple of seconds is several hundred MBs, which adds up quickly. Yes the ability to 'zoom' in while editing is nice, which is why I use 4k (my interviews are typically 4k24) and export as 1080. With birds you would want 60p. And I don't know about your experience, but trying to use the live view to chase a small bird was quite challenging and 95% focus failure for me.

If you play a video file from your camera, all the way to the right, above the bottom row of play options is the frame grab button.

Regarding your video editor, there is a work around. I looked and it does appear the corel x9 can at least edit 4k (not sure about 60p). It can also create proxies. Essentially a proxy is your same exact video file but downsized into a more reasonable video file. The software uses that to make the edits but then will revert back to the 4k file when you are exporting the final movie. On your older machine it might take quite a while to encode the proxies from 4k files, but it is a worth a shot. You could search online for how to create proxies in your software.

It's a pleasure, I will try find some resources to recommend to you over the weekend. If you have any specific questions feel free to pm me and I will try answer as best as I can.

As to whether to shoot 4K or not I think as mentioned by ethanz there are both positives and negatives. But I have to say looking at 4K footage on my 50" 4K tv looks amazing. The biggest drawback is just the vast amount of space it takes.

To be honest unless you want slow motion or screen grabs of fast subjects (although for screen grabs I would probably break the 2x shutter speed rule so that you can freeze the motion in video, this will make the video look weird though) I would just go with 4k30p.

 

[Jack Douglas]

Thanks guys. It's always very painful and frustrating getting started when you don't have someone to run to for help. Right now I'm trying to do too many things.

The 25 minutes or so of 4K60 I did was nothing at all just trying out the card to see if it would keep recording. When I do actual bird video probably 10-30 seconds would be long, so I think 4K is no problem.

I have a request active with Corel (uploading about a 3 sec. clip of a chickadee - around 300MB!!) regarding why I can't load my 4K60 clip into the timeline. I don't even know if I'm following the correct procedure. Of course impatient me doesn't want to watch 3 or 4 hours of how to video help.

Sounds like I should relax and let my wife get a 4K TV. She's a rare bird, the type that pushes me into new expensive photo gear when I'm resisting. :-\

Jack

 

[ethanz]

Lol, yes get her a 4K tv if you want to.

My guess is Corel can't read 4K60p. I didn't read it anywhere, so its just a guess.

What was your experience with keeping focus of the small birds in live view video?

Feel free to PM me as well.

My experience is not going to be typical because I was shooting with 800mm and the bird was not that small as a result. The tracking was excellent and the focus quick and it had me wanting to do more. I uploaded 3 seconds of a chickadee for the Corel guy, if you want to look here it is:

https://drive.google.com/file/d/0B2ySR23ld7gXaHZzNnZVTkRjYWM/view?usp=sharing

This was just grab 3 seconds only to have a representative .mov for him so it's nothing worthy. Took me 1/2 hour to upload 3 seconds!!

Idk if this was resolved yet bc I only read the 1st page and got tired of reading. Cards have a minimum continuous write speed. Some CF cards rated at 90-100MB/s only ahve a continuous speed of 20MB/s. Which si why it will record a while then stop. The NEWEST CF cards have a continuous speed of 65MB/s which is why they will do 4k 30p at 500mb/s or 62.5MB/s. Also with the Sandisk CFast 2 cards you have to do full format every now and then bc they slow down over time. My 64GB CFast 2 card stopped recording any 4k then I did a FULL FORMAT and it was fine again. Sandisk has a specific program for their cards to do this on their website. Their CF cards must not have this issue but will only do 30fps 4k.

 

[Jack Douglas]

Just thought I'd update that the TS128GCFX600 Transend CFast card referenced earlier in this thread that I bought for around $130 CAD has not presented any problems with 4K60 so far and I'm toying with buying another because it's big and not expensive relative to CF cards and can be used for photos if video is too challenging.

I had trouble playing back 4K60 on my computer but not anymore after downloading Canon's Video player, which also facilitates frame grabs nicely.

Since I'm new to video probably all my questions are pretty clueless. Does 4K60 play back at half speed and if so since it seems to, can it be used to produce video at normal speed.

I've pretty much figured out the camera relative to video but on the processing side I don't know where to begin both in learning and in acquiring software.

Corel is still working on my issue with not being able to open my 4K60 files and I've uploaded samples for them but it's taking a long time. It's video studio X9 that I have and it's supposed to handle .mov.

[Jack Douglas]

Just checked - the card I bought was $120 and it's now listed at $220 from the same place! Guess that changes my re-purchase plans.

I'm glad you got it to play. Where is this Canon video player?

Regarding playback speed, that is a difficult question. I have made 60p movies and played on mac computers just fine with normal speed. But I played some 60p movies on a windows machine and discovered that it was half speed (the audio was normal speed though...). So I won't be much help at answering that Jack.

Sorry I can't remember right now which Canon site. I just checked one and it wasn't there. I'll try to find it later. It's EOS MOVIE Utility. Honest, it's on my computer right now.

Found it in history a few days back! Boy have I wasted a lot of time on the internet lately!!

I see that there are two types of Sandisk CFast cards, one with a little video symbol in the bottom
Left corner and one without.

Can I record 4K 60fps on the "non-video" version?

Cool video, Jack! I love chickadees. We have an endless stream of them all day

Was that an 800mm prime or 400mm with a x2? The vibration is very bumpy, but there are super clear paused frames. I can see why you'd want to do more!

Thank you for sharing!

 

[ethanz]

He has the 400 DO IS II with a 2X III. At that FL it is very hard to not be bumpy lol.
