Fast AVI trim?

[jrockow]

I've captured around 84 GB of raw AVI footage.
I'd like to trim the last 20 mins.
My quick test with VD indicates it will take hours to "save" the new edited AVI.
Is there a quicker method?

Not that I know of. But remember you can trim, filter, and compress all at the same time, so there shouldn't be any need to store a separate trimmed version.

Did you set Video and Audio to "Direct stream copy"? What you're trying to do can take a few minutes, but not "hours".
BTW: Is your footage really raw uncompressed data? Or did you use a codec like Huffyuv or DV? I don't see why someone would want to use raw video (except for testing HDD speed).

The codec I used is Huffy.
As I remember it, I did have both the audio and video direct stream selected. Is there something else I'm missing.

I just tried it again.
I noticed that even though I selected direct stream for video, when I start to save the trimmed file and look at the "Perf" tab in the status window it shows that NO video streaming is enabled.
The estimated total time to process is over 2 hours.
I must be missing something?

How fast is your harddrive? What is your computer?
I don't think video streaming is supposed to be enabled - it is not direct stream copy but weather or not the video is displayed (I think..)

If you are trying to save the trimmed version to the same harddrive,it should be very slow cose hdd head hase to read and write large amounts of data almost simultaneously. So it really can take 2 hours,even more. You can test it this way: 1) look at cpu usage in Task manager. If it is not 100% than bottlenech is harddrive (or network share) 2) just start copiying that big file to any place and see what windows writes about how much time is left.

I estimate it takes me about 1 minute per GB to transfer a file from my D: to C: (both drives are on the same controller), so to me it's not unreasonable to estimate 2 hours for 80GB being read and written to the same drive.

:confused: I still don't understand why you want to trim this thing, since it's so much easier to just trim it when you recompress it... (You are going to recompress it at some point, aren't you?)

I think I finally see the light!
I will try to do the trim the next time I send it thru CCE.
Thanx.
