What's the optimal length for my video?

We suggest 3-10 minutes, depending on your topic. Surgical procedures may be longer, but please divide your video into sections (for example, parts 1, 2 and 3), with each part less than 10 minutes.

How can I improve the audio?

We recommend using an external microphone such as the Audio-Technica ATR-3350IS (US$ 29 on Amazon) or Blue Snowball iCE Condenser Microphone (US$ 49 on Amazon). If this isn't possible, use your headset microphone but position 4-5 inches from your mouth. After recording, use a basic noise-removal filter to optimize your audio quality. 

How can I improve the video?

A few suggestions:

  • Record in HD video. Set your Apple iMovie or Windows Movie Maker settings to HD resolution.

  • Select 16:9 settings and fade transitions. If you're creating a video from a slide presentation, configure your PowerPoint settings to 16:9 slides and use fade transitions.

  • Use plentiful lighting. If you're shooting live-action video such as a surgical procedure, provide lighting from various angles.

Can you recommend tools to create videos from a screenshare?

For recording a screenshare, we recommend Loom or Apple iMovie and QuickTime. If you'd like to create graphics and visualizations, we suggest BioRender.

Can I request a "starter" package to help me create videos?

Absolutely, please email us at to request your video starter package. Each package includes a high-quality microphone, mobile device stand and other helpful items.

How can I send video files to you for post-production and uploading to Case?

We can use Dropbox, Google Drive or WeTransfer, whichever you prefer. (Note: if you use Wistia, we will download your video directly. No need to send your video). Please send your materials to

Any additional tips?

We like this list from Wistia. Another list of suggestions is here.
