in this video i do a side-by-side comparison of prores versus
hevc on the iphone 13 pro ultimately to find out how much better is prores
or is it even noticeable i'm rafael and welcome to the channel
this is a follow-up video where i did a prores versus hevc
on the iphone but many people pointed out that the comparisons were with slow movements
and that both codecs would perform well in those cases which is very true so in these
tests i did many fast motion tests in different lighting conditions and if you are interested
prores will be available in ios 15.1 or you can get it now through the beta program or
in filmic pro i rigged up two iphone 13 pros together so i was getting the exact same motion
and lighting in both shots let's see if you can notice the difference between these two shots
you know
take your best out show me what you got no you can't resist you know i'm ready for this i just
do what i do i ain't got nothing to prove so just roll with this yeah baby roll with this
already
did you guys notice that the hevc codec really does struggle with fast motion
as it should and that prores definitely retained lots of sharpness you can see in the side by side
freeze frame that the details of the face with the hevc are blocky and mushy but both prores and hevc
pooped the bed when it came to low light filming looking at the lights you can see the noticeable
compression in both shots and looking at the staircase shot both images look pretty bad
and this is all due to the physical size of the centers and the amount of light that is able to
get in in both cases the iso is pushed pretty hard to get usable images and it may be better
to use an app like filmic pro if you're using two iphones that way you can match the white balance
on both devices and avoid color shift from clip to clip the prores file sizes are pretty
ridiculous a 20 second clip is almost two gigs where the same hevc clip is about 53 megabytes
it's pretty staggering the iphone records in prores hq which is one of the higher bit rate
settings and it retains a lot of information in comparison the sony a7s iii the r6 and the r5
also recording the hevc codec for its default setting it's a really good 10-bit codec for the
size to quality and yes the a7s3 can record in a higher bit rate but just as pro as the
file size does become much bigger also with more testing i found that airdrop 10 files at a time
work best more than that i actually found that it failed very often so you guys were 100 right that
testing with fast motion was needed to see that prores was great in ideal lighting conditions
and it will produce a sharper image so that begs the question will i use prores now
still probably not considering that if i am doing client work i don't see myself using an
iphone well at least not yet unless there was a shot that would benefit from the form factor like
getting the camera into a tight spot that larger cameras couldn't fit into or as a crash cam or if
i needed some underwater shots that were unplanned these are cases where i would be happy that prores
was on the iphone and i would use it gladly but i wouldn't design a whole shoot around using an
iphone at this time how do you plan on using prores on the iphone is this something that
you are actually looking forward to remember give this video a thumb bump also i live stream on my
second channel where i deep dive on the creative process as well as freelance financials so make
sure you check that out as always fix it in camera and then finish it in post thanks for watching
