When uploading multiple files on the Mac, sometimes your browser will become unresponsive and the following error message will popup:

A script in this movie is causing Macromedia Flash Player 8/9 to run slowly. If
it continues to run, your computer may become unresponsive. Do you want to
abort the script?

This is an issue with the performance of the Flash plugin on the Mac. Clicking “No” will allow the script to continue and it should complete. Sometimes however it will stall completely. These are known issues with Flash on the Mac and we’re doing what we can to resolve them.

So, yeah, we live in a tense world these days. A world often made more tense by firewalls that stop you from uploading movies to Jumpcut. We’ve encountered problems with uploading to Jumpcut ourselves from Microsoft Windows when we have slap-happy and access-denying “security software” which, depending on the configuration, causes the upload to hang mid-way through, or prevents the upload process entirely.

So, continuing our tradition of subtle solutions, give this a shot if you are having trouble uploading from the Microsoft Windows family of operating systems.

NOTE: Please turn any services you have turned off back on after you have completed your upload successfully, if you want your computer to be secured against unauthorized network access. Thanks.

For McAfee Security Center users, disable some McAfee Network Services, such as the obvious (”McAfee Personal Firewall”), but also the “Parental Protection”, the “Network Scanner”, and probably a few others. If you are still faced with a question regarding “Trust this network”, you should say “yes” to this. That is, if you trust the network you are currently connected to.

While the above may fix the problem, if you have to get serious, we’ve been able to restore upload functionality by stopping the following McAfee Windows Services from within the Administrative Tools’ “Services” MMC:

• McAfee Personal Firewall
• McAfee Redirector
• McAfee Privacy Service

For security software from other vendors, you should probably disable any “Personal Firewall”-like service if you are having trouble with uploading files to Jumpcut. Of course, we do offer our E-mail Uploader service to registered users if you just can’t get upload to work through Jumpcut’s other uploading mechanisms.

If you are not sure of the wisdom of performing any of the above steps, you are probably correct to doubt it. Seriously. Permanently disabling your security software on today’s Internet is not a great idea, if you value your data on your PC.

If you use HTML in your flickr set names, they will not appear in the list of Flickr sets during import. To correct this, remove the html from your flickr set names, then attempt to import from Flickr again.

Images with certain tags won’t be imported. Make sure all of the tags on your Flickr images are at least three characters long, and do not contain special characters.

Video files can be pretty large and may take some time to upload, especially over a slow connection. However, make sure you’re not trying to upload something larger than 100MB. If you are, the upload process will appear to keep going, but the upload will not complete. Check your file sizes before you upload. We’re working on a fix for this.

Currently Jumpcut doesn’t allow files larger than 100 meg. Quite a few of our users have larger files that they want to use on Jumpcut.

In order use a video clip that’s larger than 100MB, you’ll first need to break up the file into multiple clips. Each clip can then be uploaded to Jumpcut individually.

One utility you can use to split up your clips is Easy Video Splitter. This utility is available on the web, for a 7 day trial, at the following URL:

When uploading some 640×480 MPEG-4 video files, only the top left 320×240 of the video frame will be visible after upload. This is a known issue with our video decoding process. If you’re experiencing this issue, you can try converting your video to 320×340 or another format before uploading.

If you’ve uploaded a mobile video file and the audio was removed from the clip, most likely this is because your device is using the 3G2 video format. This format uses a Qualcomm audio format we don’t support yet. The clips will still play correctly, but there will be no audio.

We hope to be supporting videos with this format very soon.
