May I ask why ProRes isn't practical for you? Would help others to suggest a workflow that would work better than what you tried before.


My main use case is family/holiday videos. Saving massive pro-res files would fill up the space quickly and I’m not sure how to process them into HEVC quickly and simply.


Higher bitrate HEVC won't be any smaller than the same bitrate ProRes.

Why would you think that it would be?


You must not have tried ProRes on the iPhone. ProRes HQ consumes around 1.7GB per minute, which is an order of magnitude more than the HEVC bitrates.

Apple: "ProRes files are up to 30 times larger than HEVC files." [1]

I don't even have a clue how to force HEVC to use the same bitrate a ProRes file would use. HEVC is very efficient, and does not always use the full amount of bitrate being allowed. That's its the entire point for being. Trying to get "high bitrate" HEVC is one of those "you're holding it wrong" moments.


HEVC, and H264 for that matter does have an "optimal quality" mode, which depends greatly on the source media, you could get full bitrate for highly active footage with tons of movement or you could get tiny bitrate if you are just shooting a still image for 20minutes.

They also both have inter and intra frame compression modes.

HEVC or H264 at the same bitrate in interframe mode would produce the same size files as Prores.

Regarding the comment that Apple Prores on iPhone is huge... We aren't discussing an Apple product here unless Apple bought Blackmagic while I wasn't looking.

Prores has it's use cases, go look them up, if you really just want to quickly shoot family vacation videos and not have it take up a ton of storage open the Apple camera app and hit record, the blackmagic app and Prores is likely not for you.

Whathahuh? BMD just released an iOS app to use their software on an iPhone. So, which device are we talking about that isn't an Apple device?

>Prores has it's use cases, go look them up

Thanks, but I'm well aware of what ProRes is. At this point, I'm just assuming you're a troll.


Video encoding is a software feature, the sensor doesn't pick up Prores or HEVC therefore the product you are talking about is the software. The hardware has very little to do with it the video encoding other than possibly provide acceleration.

As I said in the other comment in this thread, if you don't need prores you probably don't need to use the BMD app since the footage captured in HEVC on the stock app is likely good enough for your use case.


I think this is just wrong. I don’t want “the same bitrate as ProRes”, I just want higher bitrate HEVC. For example YouTube has recently added a “high bitrate 1080p” option, which is still 1080p but less compressed and therefore better quality.


To understand you correctly, you want an app designed to shoot video for videographers in ProRes who usually shoot video in ProRes or raw to add low bitrate HEVC, the same low bitrate HEVC you can get in the stock camera app?

Sounds like scope creep not targeted at their intended audience.

Likewise what would be the difference between adding a 45mbps ProRes option vs adding a 45mbps hevc option? That fact it is hevc? They would take up the same storage space.
