Pro Tools AVoption 5.0 and 5.0.1 and AVoption|XL 5.0.1 are only capable of handling one clip per session. However, a sequence containing multiple clips can be imported from an AVID system or other source using Digitranslator. If a video digitize is aborted midway through then the clip must be re-digitized from the beginning. AV Option and AV Option XL 5.1 and higher can have multiple video clips on the timeline simultaneously.
