I start with a100Mg 27 second DV AVI file which plays fine in media player.
I Load it into a AlamDV project and it plays at about 1/2 speed.
I Export the file uncompressed to DV AVI file and that exported AVI plays at about 1/2 normal speed in media player and pinnacle, etc. The new file is slowed down on export.
I am using the Matrox codec.

I read that normal play speeds might not be expected within AlamDV but if the output file plays slow....well then the output is useless.

Any ideas?

Work with small files as a time. Try exporting portions of the file from your NLE. (<10MB) Then edit each portion with AlamDV2 (add the effects, etc.). The export each portion back from AlamDV2 and piece them together with your NLE sotware. AlamDV2 isn't really meant for large projects so you have to work with small clips at a time.

Thanks for the reply.

27 seconds is too long?
Am I mistaken or is <10Meg about 3 seconds of DV AVI?

Dang...doing effects in DV will take forever at 3 second long projects. sad

What I do, I have a 20 minute uncrompessed file. And from Alam I export every clip or scene, depending on the length, seperately.

Is a 27 second scene too big? really?

The orginal file is uncompressed, the export is uncompressed.

The exported 27 second scene has little lines in the motion objects and the scene runs at least 2 times to slow.

What is the max file size I should ad to my project and what is the max file scene time I should export for DV AVI?

Thanks!!!

It's not the number of seconds long your footage is, it's the file size. When you input a 108MB file, you most likely will export with the same compression settings, meaning a slightly larger file than input. Large files are harder for systems to manage around with at a time, unless you have a nice spec comp. Editing in portions is the best idea.

Hey DigiSm89...thanks for replying!
Can you actually tell me the file size I should work with?

Uncompressed DV AVI is 3 Megs per second!! What is a realistic clip size to add an effect to?

I just opened a project of less than one second!!! It is 1 meg in size. There are seven total frames to this DV AVI....and the exported file of the same clip from AlamDV, with NO SPECIAL EFFECTS ADDED, now is played back in slow motion and is 12 MEGS!!! The same lousy 7 frames is now more than 1 Meg per frame!

I need help....real help please....It can't be file size.
