After downloading a video it's then choppy and slow, whether I use my mobile or laptop.

After downloading the video is choppy and laggy.

I tried it on my android phone, my laptop (browser: chrome , firefox) , and via the Laptop app.
I tried viewing the clip in my phone , with vlc and the standard windows 10 media player. Since its a mov file i tried converting it to mp4 first which didnt work as well. if i open the dropbox link where the clips are uploaded they are not choppy. I dont know what to try anymore. Any ideas what is going on?

I have a solution! Basically go to files right click on your keypad then u should see a tab of options. Click the one that says “open with” click the option that says photos as it takes you there save the video on files you can also trim it so it’s easier and the once you save it, it lets you change the format for example if the file is in mp4 it lets you change the file to any supported file. So that you are able to see the download video. This happens because the video may not be supported in what ever app or program you’re trying to use to open it. Or In some cases, a choppy or laggy video could be caused by an error that occurred during the download process. For example, part of your MP4 movie or 4K film file might not have been downloaded correctly or could be corrupt. Re-downloading the videos might be a simple way to fix choppy videos on your device.

Hey @amik, sorry to hear you're having issues with this.

Can you please let me know if this happens with just this specific mp4 file or if it's affecting other files as well?

Have you made sure that your devices (and media players) have the necessary codecs to play this type of files on your machines?

If you could send us a screenshot of how this looks like on your end, it'd be very helpful too.

Let me know what you find!

A screen shot won't help since The video starts in slowmo while the sound is played at normal speed. The file is 163 MB large. I have this issue with all files I try to download. The clips are often still or in slowmo, then sped up or just slowmo in the beginning and then they jump through single pictures of the clip just as if it's trying to keep up with the audio.

VlC is able to play .mov files, what Codecs do you mean?

Walter

I was referring a codec pack you can install on most media players to enhance the file types they support @amik

Also, just to clarify, you can preview the files normally on our website, right?

amik

I didn't install anything like that, but since every player has that issue I guess it's not that?

Yes. However as soon as it downloads as "offline viewable" it won't work either. If I clear the cache of Dropbox the clip plays fine. It's connected to downloading it on any device 😕

Hi @amik, thanks for the added info!

You mentioned it at the beginning, I just want to clarify: the preview doesn't work when you download the file using the web, desktop and mobile app?

You also mentioned you're accessing the file using a shared link, right? If so, can you try adding the content to your Dropbox account, and check how they preview?

amik

Yes Exactly!

Yes I did, it has an issue too. As long as it's online it works. However As soon as it's downloaded/cached as offline viewable it will put out an Black screen with "Error while loading File". And not play it at all.

Walter

Would it be possible to send us a screenshot showing the error you're getting so that we can have a visual too @amik?

Hey There, I'm having the exact same problem as @amik. I know this is a very old thread, but any chance I could get some help?

The preview is perfect in Dropbox, but is either choppy or doesn't work when downloaded. The files are all MP4 and 4gb up to 60gb. I've tried converting to .MOV but that doesn't do it. I've also tried reproducing with Windows Media Player (doesn't work at all / cites an encoding issue), Quicktime (works but super choppy), VLC (only plays the audio).

Any thoughts?

Hannah

Hey @ScottS1, thanks for bringing this to our attention.

Do you currently have these files saved to your Dropbox account and accessing them from the website or are you accessing them from a Dropbox link someone sent you?

If they're saved to your Dropbox, instead of downloading them from the website, have you tried syncing them with the Dropbox desktop app?

Hello-

I am also experiencing this. I recently received a shared link to access my wedding videos. I downloaded them on my Mac laptop and moved them to a flash drive. When I played them on my Mac it was very slow and choppy with the sound being at normal speed. I also tried to download directly from the link on two other laptops and it said “it uses unsupported encodings” when attempting to play.

Best,

Ashley

Sorry to hear this happened, @Ashley Remon . Can you clarify the file extension of the video files in question? What about their size?

If you haven’t tried this yet, can you also open an incognito window on your computer and download one of the videos from there? Do you experience the same issue?

Ashley Remon

Hi@"Nancy"

The extension is .MP4

There are multiple videos that vary in size but the majority are under 1GB. I just attempted in the incognito window for a 128.27 MB video and it did the same thing. It was just choppy and lagging.

Jay

Hi @Ashley Remon, could you try using a different browser to preview the video on the site?

Regarding downloading the video, could you also try using a different video player in order to see if this is a codec issue on the video?

Ashley Remon

Hi there,

The video plays fine on the webpage. The error occurs after downloading and when attempting to play the video. I have used 3 different types of media players. One plays it but choppy and the other two cannot play at all.
The videographer informed me that the videos are in 4K and sometimes it just depends on the device.

Jay

That is true, 4K videos do require a powerful CPU to play it normally at full quality, so it does sound like the issue isn't related to Dropbox in this instance.

Do you require any further assistance?

Ashley Remon

No, thank you.
