Changes Bitrate and File size after sync.
I hope someone is able to tell me what is going on here....
I have made a 4k 60PFS recording on my iphone 8 plus.
The file properties of this mov file is around 42 MB an the Bitrate is around 39000 KBPS..(see photo)
When this file is uploaded to Google Drive the file properties stays the same...(as expected)
However !!!
When I upload this file to dropbox the filesize became around 64 MB and the Bitrate has changed to 57000 (see photo)
The uploaded file is terrible to watch .... stuttering and stuttering etc....
Why is this changed after the upload to Dropbox ?
I would expect no modifications.
Have tested this a couple of times with the same outcome everytime.
Anyone ??
- Wow... you are 100% correct.
Seems the Original file is not playing very well on my computer. (high specs...;latest I7 and one of the fastest GeForce Card and still choppy)
Thank you very much for helping me out.
Now I know exactly what is going on.
Thanks !!

How are you uploading and how are you downloading (from where)? - MarkYou've not answered the question..... we cannot attempt to help if you wont. Dropbox doesnt change the files in anyway so something else is happening.
How are you redownloading them?
The website at www.dropbox.com/home and shared link etc. I am redownloading bij the dropbox application on windows 10 and the sync tool on the Synology Nas server...
Both show the wrong Filesize and bitrate..Also when I check the filesize in the dropbox webbrowser (so how it is on the the dropbox server) it also the wrong filesize...
It seems the change is done by the upload procedure.

- MarkAre you using the Dropbox official apps to upload?
You using Camera Upload to add the file to Dropbox?
If so can you try adding it manually via the + symbol. - Are you using the Dropbox official apps to upload?

Did the manual with the + symbol and the share button ... tried all.
Stil the same adjustment to the file - MarkiOS 11?
Which version of Dropbox?
I know there are some issues with uploading in iOS11 so it maybe worth logging a ticket at www.dropbox.com/support which you can then track at http://dropbox.zendesk.com Yes correct IOS 11.01
Dropbox version IOS 64.3.4
Dropox version 35.4.20..
Also did the upload test with Onedrive ans just like Google drive no adjustments...
It only happen with Dropbox
- MarkYou need to log a ticket with support I'm afraid then.

Hi,
Could you provide the following information please to help investigate the issue further?
- Have you edited the movie in any way? Via Photos app on your phone, or iMovie?
- Do you have Camera Uploads turned on under the Dropbox iOS app settings?
- What is the selected option under "Settings -> Photos -> Transfer to PC/MAC" on your iPhone 8 Plus?
- What is the selected option under "Settings -> Camera -> Formats -> Camera Capture" on your iPhone 8 Plus?
- Please share a link to the smaller 42MB 39000 kbps video you mentioned via a support ticket. A link to the file in Google Drive should be fine.
- How are you uploading to Google Drive and OneDrive? Directly from your phone or from your PC?
- What PC OS do you have? Is it Windows 10?
Thank you.
Akay
