That's some good news, so let's get started with the project.
Regarding this workflow, I need you to give me a little bit more information. So I will need to know the following:
Is the trimming of the clips going to be done manually or is it going to have a time frame that can be configured automatically?
If the clipping is automatic then the S1000 will suffice.
If it's a manual clipping, probably the costumer will need a S1000 and F1000.
S1000 - Will record from SDI signal (24/7) and will generate the master clip without interruption. Simultaneously it will generate the second clip, the one the customer will work on. Both will be saved in the storage.
F1000 - After being sent to the storage, the F1000 will allow the costumer to edit the file while it is growing.
"Please advise me how to trim the clip during record the SDI signal using S1000? "
There are two options, first you have the option of creating a Clip List, where you can set the in/out point and the duration of the clip. And the second you can choose in the advanced options (advance / profile / frame chase) the time between which the clip will be automatically Cut.
