Video captured in real-time uses up a lot of RAM. To save space, an editing program typically will not fully render a whole video, so some parts end up not completely ready to view. Thus the video requires a lot of further work from you to prepare it for full use. Here are some rendering tips:
- Check the settings on your editing software to determine if it will render automatically or if you have to do a manual render.
- Determine the codec you want to use to export to digital format. MPEG2 is a good choice for DVD and other distribution. QuickTime or WMF work fine, but produce huge file sizes.
- Choose the resolution. The better the resolution, the larger the file will be.
- Audio is often rendered and compressed separately, so you need to choose codec for audio too. AC-3 is the most common and best for DVD authoring.
- If you’re just going to upload your video online, and don’t need physical storage (like DVD), you can use a singular file type that saves your video and audio in one place. Choose singular file type during render and compression—it’s usually the last decision you’ll be asked to make during the process.
