Hardware and Accessories / Slow CF Benchmark on Computer
« on: November 21, 2015, 01:35:08 AM »
I bought 2 Komputerbay 1066x 128gb cards. I will be working with a 5D3 (shooting raw), but don't have access to the camera yet so can't test with camera.

I'm on a mac and tried using F3 software to test speeds on the two cards. Got an average write speed of 75MB/s on both cards. I also tried the GUI version called "sdspeed", and the black magic disk speed test, all with the same results.

I'm using this transcend USB3 card reader:

Are those the speeds I can expect in camera? If so I'll need to send them back, but I've heard the 1066x are usable for recording continuous 1080p MLV with sound.

General Chat / Any Black Friday deals for CF cards or Hard Drives?

I need to buy a couple CF cards and hard drives for an upcoming shoot in December, wondering if I can save a couple bucks.

Raw Video / Getting Ready for a Short Film
« on: November 02, 2015, 08:40:40 PM »
Hi, I've shot a handful of music videos in MLV format, and I've got the post-processing down. But I've got a few questions before jumping into the narrative format. (I'll be shooting on a 5D3)

Firstly, I'd like to purchase a couple CF cards, are 128gb 1066x Komputerbay cards a good choice? I've only used Lexar in the past and I read mixed things on Komputerbay, some people say they've never had problems. Budget is tight so looking for the best deal.

Secondly, I never realized that people expose differently for Raw. Is it generally the best idea to expose to the right? Expose brighter than usual? I wish I could experiment but I won't have the camera until a couple days before the shoot.

Thirdly, when shooting 1080p 24fps, I've never had any issues with corrupt files or pink frames or anything I read about on the forum. Have I just been lucky or are those issues more for non 5D3 cameras? Should I be checking all my footage dumps to make sure everything is coming out properly or can I rest easy and focus on the next shot?

And lastly, if anyone has experience shooting MLV in a narrative format, what issues did you run into? Did you record sound to help you sync in post? Or did you keep sound off and use a clap board?

Raw Video Postprocessing / MLVFS + Davinci Resolve Black Clips
« on: September 01, 2015, 09:26:03 AM »
I converted some clips using MLVFS and Resolve to ProRes 422 without any problems.

I decided to go back and convert them to ProRes 4444XQ but now those same MLV files aren't loading right.

I can use MLVFS to create the CDNG folder, and I can view the individual DNG frames in finder.

But in Resolve, when I try to drag them into the media pool, there is a very long load time and then the clips are all black. It does retain their framerate, resolution, and length, but they're entirely black.

When I check back in finder for the CDNG files, it seems that MLVFS has quit working and they've been ejected.

Again these are the same MLV files that gave me no trouble before. Unfortunately I don't have any other MLV files to test.

I tried converting to CDNG with a Rawmagic and those CDNG files loaded fine in Resolve. Seems like this is an issue with MLVFS timing out?

I'm using the latest version of MLVFS and Resolve 11. Even tried Resolve 12 beta.

Raw Video / Corrupted frames with 60p
« on: August 29, 2015, 03:39:49 AM »
I've been shooting 1080p MLV with sound and never had any problems. Decided to try 60p. Tried different resolutions and frame rates. 48 and 60fps seemed to record fine at 1280x432 (720p after de-squeeze). I shot continuously without any skipped frames. Some shots lasted for several minutes. Absolutely no problems on the recording end.

After importing, several clips have random corrupted frames. I see some people repair these frames with hex editors but it is usually for clips that were split after 4GB limit was reached (repairing the footer). For me it occurs even on short 5 second clips.

Is it just too much processing or not enough card speed? Is there a fix?

Raw Video / FPS Override - Playback Speeds
« on: August 11, 2015, 12:16:58 AM »
When I set FPS override to 1, 2, or 3 fps, I get a file that plays back at 23.98, a time-lapse, which is what I want.

But when I set it higher at 6 or 12 fps, I get a file that plays back at 6 or 12 fps.

But it only does this when I'm recording in MLV. When recording H264, the end file is always 23.98.

Raw Video Postprocessing / Editing and CC in ProRes
« on: October 28, 2014, 05:09:42 PM »
I'm thinking of filming an upcoming project in RAW on a 5D III. My workflow is editing and color correcting in FCPX. I've been testing with MLRawViewer and exporting ProRes and it's working fine.

My question is, if I'm going from RAW to ProRes and never going back to RAW or DNG, then is it worth it to film RAW at all? Will there be major benefits in quality and color depth? I know ProRes 4444 is better than H264, but enough to warrant the whole process and file sizes?

If anyone has a better workflow for FCPX, please let me know.
