  • A possible problem with BRAW

    I received my UMP G2 this weekend. Although this is not a normal test, I wanted to test and see how long before I get drop frames on my 256Gb CFast card without stopping it. I was recording in 4K DCI 24fps in BRAW Q0. The good news is I got through 241Gb before the URSA displayed that my card was full and no drop frames. I transferred this Huge file to my Mac SSD and tried to load it on the BRAW Player. Well, my Mac just froze-up while BRAW player loads the file. That is when I though to myself... this is a potential problem with BRAW since it generates just one file. What if I was continuously recording an event in BRAW that took over 240Gb of content in one file? Will it be able to load into an NLE and if so, how efficient will that process be? If it will freeze Resolve or any other editor, then that's got to be an issue.

    Ever since recording for an extended period of time became possible, people have always been worried about this with any format. But as computers and software (and cameras, of course) advanced it became less of a concern.

    I don't have an answer for you, but recording in a proprietary format that's only supported by one piece of software puts you at a disadvantage. Maybe also record traditional ProRes externally if possible?

    One of the best things about CDNG is that you could make several clips out of your recording. You could literally pull the card out of the camera while recording and your footage would be fine besides maybe the last frame.

    I love Blackmagic but I would never record anything longer than 5, 10 minutes with these cameras.

      I miss CDNG.
      I will use ProRes for long recordings but it would be nice is have some feature in the future firmware OS upgrade that will allow to split BRAW files into usable chunks.

        And you haven't tried to load it into Resolve, but wrote that post instead? Seriously

            Me too. EYu, the issue may be more of your Mac and the player utility, than the BRaw file per SE. Like Frank said, you need to load this into Resolve, and you should really have known this, given your previous experience with BMD cameras.
            Cheers

              Okay guys, I should have done that first. My bad. Yes it works on Resolve but I have a beefy box for it. I was hoping to see braw files on the player with the MacBook Pro with its top-end configuration.

                So no Ryzen 3. No PCIE 4. No multi M.2 setup. No Nvidia quadro.

                I don't want to do the Mac vs PC thing but...

                  What happens when you try and play it in Resolve on your Mac?

                    Oh, come on, I can work with BRAW just fine on my decent iMac. The codec is not very demanding.
                    There might be some sloppy programming of the player, though, maybe they never tested such long files. In Resolve, I've been working with very long files for post time-lapse.

                      Well I don't have Resolve on the MacBook Pro because when I had it before it was slow for viewing CDNG, hence I removed it. For field work, I was hoping to be able to use the player just to view the clip and show it to the director and not for editing/grading purposes. I would have thought that BRAW would be a codec that is not demanding (like CDNG).

                        Which Macbook Pro do you have?

                          FWIW I can play 4K braw 12:1 fluently on a 2015 Macbook Air. Might be 8:1 but don't know how to check from the file.

                            MacBook Pro 2015 with i7. BTW, I just tested again and I can load and play BRAW 4K UHD 8:1 and 12:1 up to 2-3 minutes in length. Anything larger in size and/or length it just freezes when loading.

                              Well, assuming you have 16GB of ram, that coincides with the size of about 5 minutes of 8:1 braw. Seems like poor software design.
