What are your system specs? Do you have the latest version or QuickTime? What happens when you import the files onto a non-quicktime sequence? What happens if you right click on the video file in the bin and choose create sequence from file. Then drag the other file onto that sequence?
My QuickTime version is the 10.4 (no idea if it's the latest one)
What do you mean by my system properties ? My mac ? If so then its a 16Gb 1600MHz DDR3 + Nvidia Geforce GT 750M 1024MB, an OS X Yosemite version 10.10
"What happens when you import the files onto a non-quicktime sequence?", well I don't know how to create a sequence before dragging a file on the timeline on this premiere, so I dragged the "Second video" first and it created a sequence with AVC Intra 100 1080i
preview file format AVC-intra class100 1080i
what's weird is that I could add the second video once, but not twice, and I can add the "first" video several times (it's weird because the sequence was created from the second video's properties)
To answer your last question, the same thing happens too. I can create another sequence with the "Second video", add the "First video" 10 times but I won't be able to add the second video a second time.
On the other hand, when i created another sequence with the "first video", I will be able to add the first video as much as I want, but I won't even be able to add the "second" video once.
Ok. I have a PC. So I assume your stuck with QT based codecs, correct, (I haven't used a Mac in ages).
The temp files might be corrupted: What happens when you close PPro, delete the temp/conformed files, then reopen PPro, let it create new ones and try again?
That second video file might be corrupted: What if you were to re-encode that bothersome second video clip to another file and use that one instead?
So, if your still stuck and you can at least create a sequence for each video, correct? Try this, create a third sequence and drop the other two sequences onto it (nesting).
Thanks a lot for your help:)
Small questions : What are temp files ? How do I find them and delete them ?
In what format do you want me to re-encode the second videoclip ? Or what do you mean by re-encode to another file ?
Also, I forgot to add something : I can't read the second video without premiere, it's a .MTS... but on my other mac I can read it (Where I have the old premiere version). Unfortunately, my other laptop is too old and heats way too easily, which is why I got this new mac + new adobe premiere version
What program should I download to read .MTS? Maybe it's the problem and im missing a codec ?
You're saying that you could play the .mts files on the old mac? That's a codec issue. Google for AVCHD to MOV converters. I found a free one at the Itunes store, I can't give you link here, but you can find it.
I gave on using multiple formats and allowing PPro to conform in timeline. I now pre-conform odd formats and stuff I get from other editors (which is old school and bullet proof) to a single format using AME. Easier on the edit and takes the guesswork out of things. I've also used Cineform's HDlink in the past and haven't needed it since CS6. In your case, you'll need a third party app to recode the file to something that PPro can ingest.
You do not need QT for a mpeg movie. MTS is avchd.
Just drag a clip into the timeline to make a matching sequence or pick a avchd preset.
