Constant Bitrate vs. Constant Quality : BRAW Showdown BMPCC6k Pro

Welcome toMatt Spade Sound & Vision, your source for in-depth insights into the art and science of filmmaking. In this video, we delve into the intricate world of Blackmagic RAW (BRAW) to explore the critical distinctions between two fundamental settings: Constant Bitrate and Constant Quality.
Understanding these settings is essential for filmmakers and videographers aiming to achieve the highest video quality while optimizing their workflow. I'll conduct visual comparisons, and discuss how these choices impact your creative process.

Loved your video man! Also thanks for making video about NOT popular but important topics! You are sacrificing views for quality! Thanks

[@mattspadesoundandvision]

Thank you for that! My goal is to stay true to sharing what is important to me and my filmmaking experience. I'm glad to have you along for the ride.

I have mostly used constant bitrate but I did ProRes Lt for a shoot at night recently.

[@mattspadesoundandvision]

How did the Prores LT footage come out? I have switched to mainly using CQ over CB in most instances, especially outdoors. Thank you!

[@SlugfestWizard]

I have been using Prores a bit more often because it is a smaller file size but I am going to try BMRAW on the next shoot because they use Highlight recovery. @@mattspadesoundandvision

Thanks for the video. Very helpful. I’m in the process of learning about the blackmagic camera and I also want to learn how to use davinci resolve.

[@mattspadesoundandvision]

Thank you and I'm hoping to do more tutorials on Resolve. It's such a great NLE.

Then YT murders the delivered image after upload... I use 6144x3456, BRAW constant bitrate 5:1 and film DR for almost everything. I do original narrative content, so I need to match those shots.

[@mattspadesoundandvision]

This is true. It’s a shame that less compression couldn’t be used, but I feel like the service would cost us money if so. Unfortunately, platforms like Vimeo decided they didn’t care about content creators.

[@gssg2010]

@@mattspadesoundandvision True indeed! After a three year reintroduction to filmmaking, I'm finally cranking out content. Housing and distributing said content is a big concern and a current research project.

[@YamilSunRay]

Thank you for the insides! A friend of mine told me something similar and I wanted to do some research. Awesome how you described it as well

[@mattspadesoundandvision]

Thank you so much. I really appreciate this and I’m glad it helped.

Thanks for sharing your helpful advice Mike! It takes some of the fear and uncertainty out of which codec to use. Question: what kind of media do you use? Sd card, ssd or cfast? Thanks!

[@mattspadesoundandvision]

I use a 250GB CFASST and a 1TB SSD. The SSD cost me 1/4 the price of the CFAST. For my BRAW formats, I'll either use CB @ 5:1 or CQ Q3-Q0, depending on how much or what I'm shooting. I've learned that things that are backlight do better in Q1 or Q0. Thank you!

[@jvpuckett1214]

@@mattspadesoundandvision Thank you so much! Do you use the Samsung ssd?

[@mattspadesoundandvision]

@@jvpuckett1214 I do! I have the T7 ( amzn.to/3tpRr9y ) which works for the 6K Pro. I've read mixed reviews of people having issues with older BM cameras and the T7 so the T5 ( amzn.to/3ttWXbd ) would be a good back up. The reason for the Amazon links is they'll at least take the drive back if it doesn't work.

[@jvpuckett1214]

@@mattspadesoundandvision Thanks so much Matt!

[@ez591]

So can you film a film in let’s say 3:1 and then shoot in Q0 for certain shots for the same film? Just to get that quality and info the Q0 would take in.. and I believe Q0 is better than Q5 correct? Thank you

[@mattspadesoundandvision]

You absolutely can! It's similar to using different camera footage and codecs. The NLE will do the transcoding/encoding work for you. I once did a feature film where 90% of the footage was ProRes. The other 10% was shot in CDNG. The beauty of Resolve was it handled both file types. Cheers!

[@ez591]

@@mattspadesoundandvision awesome. Thank you so so much ! I really appreciate the info. That’s very helpful. I’m also reading the manual to learn as much as I can about the BM camera. Thanks again!!

[@mattspadesoundandvision]

@@ez591 I'm happy to help if need be. Feel free to reach out. I'm looking to do more camera and Resolve videos.

[@carlos.sierra]

I'm really not trying to be a troll here, but this is some of the worst footage I've seen out of a pocket camera. Which export settings did you use? Also, why does your footage look so magenta? Were you using the built-in NDs? (btw, I was watching in 4K. But it wasn't just the resolution that looked bad, but also the colors - that's why I'm kind of confused.)

[@mattspadesoundandvision]

@@carlos.sierra I appreciate the feedback. I’m curious if it’s a playback issue since I don’t see the magenta cast in the example footage: for the footage with me talking I went back and forth between and old Canon 6D, iPhone, or the BMPCC. If you have a time stamp , LMK. Criticism is always welcome and I appreciate you doing so with class.
