Hi ,
1. You have an “change source timecode in header ” option when you right click on the shots in your browser . You can change the time code of the particular clip according to your source edl. Add the shots into your media pool. Now , if you go to the timeline , you will find all the shots exactly on the place where you want the shots to be. I hope that solves the first question .
2. This option is available if you have a color panel .
3. There is a kinda work around for this as far as I know and I tried . open the two edl’s in text edit , combine both into one edl by cut paste one after another . Now , when you load this combined edl into resolve you will confront a problem with the timeline timecode. The Serial Numbers will anyways dont follow sequentially . Now you have to manually drag the second bunch shots which will be at the other deep end manually with the help of ripple mode . Try this , its little difficult and tiresome but this is the work around I use .
4 . If I have understood it right , then all you have to do is save edl of the current time line , edit it in text edit and load the same edl and save as a different timeline .
I hope I have answered atleast few of them to your help.
Thanks & Regards
