What is the best way to merge a clip that has been recorded on card a then switched to card b in Premiere pro? When I bring the clips together, there is a slight glitch. Almost like there are a few frames missing.
When a long clip is recorded to ONE memory card, and it gets saved as several smaller clips, there should be no glitches between them when using the proper workflow in Premiere, which mhood mentioned. Best practice is to copy entire card contents direct to hard drive - no modifications, no utility being used - then in Premiere Import using Media Browser. This will recognize several small clips as one long seamless clip when imported. Glitch free.
However, what you are inquiring about is a recording that physically spans across TWO cards, correct? Not familiar with the C100 in particular, but in having read reviews and manuals for other dual-card cameras, they do typically advertise that "a few frames will be lost" during the recording crossover between cards unfortunately.
If you use the Media Browser import method and there are a few frames missing between the two recordings, it's most likely by design then. Check the camera manual and it ought to cover that.
I tried using media browser to import to see if that would work, with no luck. I seemed to remember media browser worked with cs6, but I couldn't figure it out with CC. Maybe the few frame glitch is normal.
I always try to avoid those situations, if I know I will be recording for a certain period of time and it is not enough I just put in a new card. I had the same problems couple of times with no luck of resolving it.
I've had the same glitch on a long clip on a single card; I was ready to tear my hair out until a friend pointed out that the entire file structure of the card needs to be copied before importing the media to premiere as it contains data on how the NLE should read the clip. However, given that the C100 records video as interlace with a progressive wrapper I can see how 2-3 half frames get lost in the switch. I use Premiere CS6 and it has automatic pulldown removal on the AVCHD clips from in-camera recordings.
