How fast cf card for 5d video

This has had zero influence for me on write speeds for video. Are you saying that just having an SD card in the camera will slow things down or do I have to be actively writing to the SD card to encounter this problem. With that said, I have notice no difference in write speeds to the CF, whether the SD card is in camera and not active or out of camera completely.

There is a tornado of conflicting information out there, and I've long past the point where it is more practical and convenient to do searches than to just ask you here and now. In clean, simple responses, please tell me, what is the most reliable CF card for continuous RAW video as in more than a minute without dropping frames on the 5D Mark II? I don't care the price or capacity. Give me a best, and a runner up.

If you aren't confident answering, please don't respond. If it doesn't work out, I'm sure I'll be back to complain. Lexar or Komputerbay, at least x. Kharak Hero Member Posts: Never tried Komputerbay. Thank you. Anyone want to be a tiebreaker? So, you're not able to write FullHD 24fps. So RAW x at 24fps is not possible for continuous shooting? So, to be clear on terms, by "continuous shooting", do we mean a full ten to fifteen minutes of continuous shooting without frameloss that the camera will allow?

Is the 4GB file size a limitation? Already people have recorded long takes of raw video in a single 12GB file! Work by the Magic Lantern developers is being done to optimise the way the code handles the buffer and card writing to improve speeds. It is sensible to leave some margin and not push resolution or frame rate right to the limit.

Below is the benchmark for SD cards. What IS the story with KomputerBay? They appeared from nowhere and offer very good performance for very small prices. Well the truth has been outed. These are quality control failed memory chips.

Is this a bad thing? Actually no. Reliability seems unaffected. The test uses a manual lens and manual camera settings. The 5D IV is mounted on a tripod and activated using a remote timer. The subject is a detailed test scene illuminated by controlled lighting. Write speed is calculated using the buffer full condition during extended continuous shooting; the total amount of data written to the card divided by the write time.

This calculation provides a more accurate result than the card access light because the the light turns on when the shutter is first activated rather than when the image has been processed and begins writing to the card. Write speed is provided for RAW image mode. The following table shows the number of shots taken in 30 seconds of continuous shooting using the 5D Mark IV.

The time does not include the buffer clearing or write time. The JPEG setting is large, high quality. The camera is set to continuous high drive mode. Average RAW file size is Average JPEG file size is The detailed test scene used in these tests results in large file sizes.

The number of images may be lower than what may be experienced during actual use, depending on the image subject. Images with less detail create smaller file sizes allowing more images to be written in the same time period. This is the number of shots that can be taken at full frame rate before the frame rate drops.
