Prepare the project first
Save a new project version, then close and reopen it. Confirm that all source clips, pictures and audio items are available. Watch the timeline from beginning to end for unfinished titles, black gaps, abrupt sound changes and accidental fragments beyond the intended ending.
Create a short test containing movement, speech, music, a title and a transition. This sample makes it easier to compare choices without processing the entire project each time.
Choose settings from the intended use
Frame size, bitrate and format affect both quality and file size. A movie intended for viewing on the editing computer may keep more detail than one prepared for the slower internet connections of the period. Avoid assuming that the largest number is always best. The source quality sets a ceiling, and excessive processing cannot create detail that was never recorded.
Preserve an archival-quality result where practical and make smaller derivatives only for specific uses. Label each clearly with purpose, dimensions or date so files do not become interchangeable mysteries.
Let the process complete
Long projects can take time to process. Avoid moving source files or changing the project during the operation. If creation stops, note the point, test a short range around it, verify the source item and simplify the most recent complex change. Work from a copied project version so troubleshooting remains reversible.
Review the file independently
Open the finished movie outside the editing project. Check the beginning, several scene changes, speech, titles, fast movement and the ending. Then watch the entire result without interruption. A successful process message does not replace editorial review.
Keep a useful final set
- The protected source media.
- The final editable project and key earlier version.
- A high-quality finished movie.
- Clearly named viewing copies created for specific contexts.
- A brief note describing format and aspect ratio.
If the file behaves differently on another system, read the independent codecs guide. For project dependencies, return to saving projects safely.
