[@noahthecubeguy]

Wow, very well explained. Love your videos man, keep up the great work!

[@LetsPlayThru]

Can’t tell you how helpful this was. Thank you for breaking it down so well.

[@a.z2972]

Please keep making these about absolutely everything to do with the a7siii. They’re so helpful thank you so much

[@BarkandJack]

Super helpful. Thanks for explaining this stuff so a noob like me can understand it.

[@towermedia5940]

Some examples would be nice imo, like how big a 3 minute clip in XAVC S 24 and 120 fps is approximately, just to get a practical understanding!

[@8Stream]

Matt, thank you so much! You’re the best at explaining complicated things in simple terms! Much appreciated!

[@brianrudolph2456]

Thank you! Thank you! Thank you! I love that you put the answer up front and explained, rather than burying it at minute 9.25. Very helpful explanation of file types, organization and functionality.

[@alf5617]

Super super helpful. I don’t like many videos, but for how helpful this was and how good a job you did explaining this, I truly tip my hat to you sir! 👍🏻

[@CraftedBricks]

Thank you for these videos Matt ! I've just bought a Sony FX3 and your videos have really helped me to get my head around all the settings and set up my camera for filming!

[@RileySorensen]

Well done Matt! I watched a different video when I first got my camera and my file sizes were MASSIVE! I thought "Matt is the guy to watch" and I was right. This saved me! Thank you! I look forward to more of your Sony A7Siii videos. This camera is a BEAST!

[@CesarLRodriguez]

Another exceptional video. Thank you for demystifying all those features. I got this camera and was definitely confused about those all different formats and the pros and cons of each. So thank you!

[@thetalkingfly]

Great Vid Matt- super helpful! cheers, S.O.

[@Louie-ty6bh]

Just want to say that you can explain things really well. It's actually a skill. Thanks for this vid =)

[@Direct19681]

Great video Matt! I’ve got my first big wedding video to shoot this Saturday and am feeling pretty confident from what I have learned from you brother! Prepping all gear this week to get ready.. thanks for all you do to assist us all!

[@whoismatt]

Thanks David!

[@DianaMarchenaGarcia]

Thank you so much, really great video and explanation, I’ve just watched it 3 times and I’m definitely gonna watch it couple of times more!

[@maruwaanmoses]

I don't shoot Sony nor wedding videos. I'm just here to listen to Matt explain things 🙂

[@stevenlear6439]

Thanks Matt for getting to the recommendation first and then fleshing it out, great vid.

[@perlmunger]

Super helpful Matt. Very concise and informative. Great work!

[@FlorenceRobbiano]

VERY HELPFUL! I am a total beginner and this is exactly what I was looking for. THANK YOU!

[@ramonbannister9498]

Good info! Thanks, Matt. This is at least my 2nd time watching this video, because I finally got my a7s iii. Depending on whom you ask, you'll get different recommendations. Well, I like Matt's the best as I even checked on my camera for total record time available. For 128 GB card: 1h 8m @XAVC S-I 24p; and 2h 40m @ XAVC S 24p 100M 4:2:2 10 bit. That's more than twice the amount of time. I also like Matt's explanation of WHEN to use S-I...Before today, I was an advocate of ALL I all of the time. But w/ this camera being 4:2:2 10bit you don't need that. If you're filming w/ lots of movement and intricate detail in the shot, that's when to use ALL I. As they say, use sparingly.

[@MaxwellAdventuress]

I have seen about four or five of your videos, and I have to say. You kill it on presentation, knowledge, relatability, and explanation. Thank you have officially subscribe and will be looking forward to more videos utilizing your expertise and experience. Thank you. Nate

[@bartlaw1074]

Thanks for getting straight to the point bro .... with the option to get more details afterwards 💪🏾🔥

[@dr.revenue3636]

Just picked up the A7Siii and this was extremely helpful, thanks Matt!

[@inabag]

Matt, whenever I look something up and there is one of your videos, I always click on it and without fail, you solve my problems every time! cheers! :)

[@flyingdroneinperu3681]

[@akirahman235]

Unbelievable. Love your videos man. Just bought a a7siii after procrastinating for years about making a film. Thanks for the info

[@MahbubAhsan]

best video by far for those who had no effing clue what these codecs are and what settings are for what ? that's a giant thank you so very much :)

[@8notes_]

I love you videos bro! This one for example is the best explanation on this topic for me. The part u explained how the codecs stop reading non moving parts of the video answers all the questions!

[@ZaynaQuader]

Thank you so much, Matt! This was super helpful and now I know why my last youtube video was a pain in the butt to edit (I was using HS). Please continue to make these videos. You've got a sub from me!
