I am translating a large film (2 h)
And all the words are wav.
One thing is certain. If you want to edit video and specially 2 H or longer, you will need a lot of storage space. Get a couple of additional 1 TB disks.
How can you translate video images from say traditional Chinese into Wolof? And how are words available in audio files?
I am translating a movie
From english to romanian
And I have recorded the words with my microphone
I just want to know
Why the preview files are going in local disk C but not in D
And how can I make those CFA files smaller?
Because of your environment variables.
What do you mean by "enviorment variables" ?
TEMP and TMP, that Windows sets automatically.
you can change the location where your media files (cfa, etc) are located by going to preferences, media. I am not at my pc now, but that is the general place to go look. change them to another drive. and do what Harm says and get yourself an additional drive or two. You will not regret it.
