My export video files are huge. Can someone tell me what I do wrong?

Hi everyone!

I just edited a MP4 video file from a Sony RX100M3 camera.
Original file is 900mb for 10 minutes.

Now after editing, I went to Share --> Local File --> Export to MP4

But the exported file I got is 1.15GB (!!) even larger than original.

How can that be? I didn't add any fancy effect.
Just dropped a fade in and a fade out. That's all!

Below are my current settings:



I am using CAMTASIA 3 for Mac v3.0.6 (98750)
My Mac is a MACBOOK Pro with macOS Sierra v10.12.5

THANK YOU for your kind help!

Patrick, I think the size is just 250mb bigger than the original, a size increase of about 1 photo. I wouldn't worry!

Thank you for your quick answer Jiggy! 

I understand what you're saying but:
- Is there any way I can have my video compressed but with a good quality?
- How can I get a HQ file exported on my hard disk?

More than 1gb for 10 minutes video seems HUGE.

For comparison purpose, I recently downloaded a 1 hour and 30mns (90mns) HQ video file from a popular hosting platform to know the exact weight.
HD video image is crystal clear, absolutely no noise and total weight is ONLY 470mbs. I was puzzled!



Any ways I can get a much SMALLER file with same exact quality?

THANK YOU!!!

Is your video destined for YouTube? If so, file size does not really matter, outside of taking up disk space in your local archive. And drives are cheap. Trying to transcode into something smaller is probally going to be more trouble than it's worth. Good luck!

I agree with Jiggy here, if it's going to YouTube it's going to get reencoded anyways so don't sweat it.

If, however, it is going somewhere else and will NOT get reencoded, you may indeed want to compress it down a bit.

Firstly, it's not very surprising that it's larger. The original off the camera did the best job it could and it had all of the original pixels to work with. When you recompress it, you are dealing with a lossy, less than perfect copy. Think of it like making a photocopy of a photocopy. The first one is pretty good, but it tends to degrade.

Still, I bet you can get good quality with smaller file size. Try out "Export to Main Concept (.mp4) instead, and toy with the quality slider a bit. You can export just a section of your video by selecting a range (red/green handles on the playhead) and then sharing. This'll save you some time instead of exporting the whole thing for testing.

Hi Paul! Thank you for joining in!

I just tried what you suggested and yes it did help to DRASTICALLY reduce the size.
By just pulling down the slider A LITTLE off the center, my video was reduced by 7 (yes SEVEN!). From 900mb to 130mb and watching the video full screen is not blurry at all.

This is GREAT news! 
Below is a screenshot showing how much I moved the slider from its original centered position.


Also thank u for the tip about "selecting a range (red/green handles on the playhead)".
Yes it may seems if not silly, at least obvious for many users but to remind the basics is always a GOOD thing. I usually just export everything for a test which is a waste of time...
Now I'll remember to do as u said. Thanks again! :-)

Try this if it helps :
Before YouTube Upload you can compress it : https://handbrake.fr/  (Default settings are ok)
It drastically decrease the size (save a lot of time to upload for free) without many loss of quality.

Hi Stephane!

THANK YOU for your very USEFUL suggestion!
So I did download "Handbrake" and had a try, just leaving all the settings by default as you suggested. The result is just AMAZING as the size was reduced FROM 900mb to 120mb without any loss of quality and I feel even crispier than already good result I got from solution above.

I watched my vid full screen on my MacBook Pro Retina 15". This is a vid where I teach Chinese handwriting. So in short, image is just a zoom of a hand writing on a notebook. This is definitely a great test to detect any blurry image, right?

Well, result is perfect. I don't know how they can achieve that but image remained crisp and crystal clear. I'd say result is very close to my test done above but I feel Handbrake gives an even better result.

Now if I moved the Camtasia slider a bit back towards the center, quality should be the same as Handbrake but with a bit larger file though. Maybe something around 160mb while Handbrake will keep it at 120mb.

So good, quick and easy solution to compress files is Camtasia (Export to Main Concept), but if we want the lightest weight possible for equivalent quality, solution is Handbrake.

THANKS again!!! :-)

I hope one day Camtesia will consider to integrate it...
