Online. Trimming module Page Published on Monday, January 6, 1997 by Gideon Ariel Trimming Module Hi- Gideon asked me to respond to your question regarding trimming video sequences that are recorded at different frame rates. When trimming several video clips simultaneously, the clips must all be recorded at the same rate. With your data you can Trim the 25 Hz cameras simultaneously, but the 300Hz clip would have to be separately trimmed. Each clip would also have to have the synch image properly specified. The ability to trim clips with differend frame rates is planned for the next revision. It clearly will be a nice feature, however it adds to the complexity of the process considerably. Please let me know if I can be of assistance.
