Why can't I upload my video to Chalk & Wire?

Video files are, by nature, larger than most other file types that you would upload to Chalk & Wire. This larger file size equates to longer upload times, which is what opens the window for issues to arrise during the upload process (internet connection issues, bandwidth issues, etc.). To reduce the time it takes for a video file to upload to the internet we recommend that you reduce its size by compressing it first. This lesson will show you how to compress your video file into a smaller and more manageable format. Since Chalk & Wire does not provide video compression tools we recommend Handbrake™, as it is free to download, easy to use and is available for both Mac and Windows users.

NOTE: These instructions are not specific to Chalk & Wire. The same steps can be used to compress a video file before uploading it to YouTube, Google Video or other internet websites.

If you would also like to edit your video to rearrange or remove specific clips and shorten the overall length of the video, please visit our Video Editing help page before compressing your video.


Step 1: Download Handbrake™

Step 1: Download Handbrake™

To download Handbrake™ go to and select the option for your Operating System. Once the application is downloaded to your computer, install it and then open it.

Step 2: Open Handbrake™ and Select your Video File

1. The option to select a video file should automatically appear when you first open Handbrake™. If this option does not appear, click the Source icon located at the top left corner of the Handbrake™ window and select Open File.  

2. Select your video file from your computer and click Open. In this example we are using a high definition movie trailer (720p) as our source file. The original source file is a .mov extension, but any video format is accepted.

Step 3: Name your new Video File and Select the Output Type

Step 3: Name your new Video File and Select the Output Type

3. Click Browse to open a browsing window for your computer and select the destination for the compressed file. Enter a new name for the video file that you are about to create.

4. Use the Devices drawer on the right side of the application to select the iPhone & iPod touch option. This will adjust the settings in the main HandBrake window for you.

NOTE: If the "iPhone & iPod touch" option does not compress your video enough, try using the "iPod" option - this will minimize the file size, but will also diminish the quality of the video.

Step 4: Compress Video

Click the Start button located in the top left corner of the Handbrake™ window.

Once the compression process has started, you will see its status at the bottom of the HandBrake™ window.

You will be alerted when the video compression process is complete. Click the OK button.

Final Output Comparison

Final Output Comparison

This is a comparison between the source (Large Quicktime™ window) and the converted output (small Quicktime™ window). The main difference between the two is the dimension and size of the video file. The smaller MP4 version is similar in size to the Flash players used by online video streaming without a massive loss of quality.
