Scrambled project video

Post by ranis »

I have some avi files made with exlim ex-s770 digital camera.
The problem is when I add them to the project they appear as scrambled video in the playback window. They only play ok if "clip" is selected, but not in "project". I can't edit them in timeline, it appears scrambled, mostly black. Please help.

Here are my Preview Window settings: ( VS10 )
Playback method - Instant Playback
Instant Playback target - Preview Window
Default field order - Lower field first

And the AVI's are:
Video Compression - ffdshow Mpeg 4 Video Decoder
24 bits 640x480

Audio Compression - IMA ADPCM
44.100khz, 4 bit, mono

Windows Media Player 10 plays them fine.

I'm not an expert on this and may not suggest correctly however as you have not had a response I will ask a few questions/make suggestions which I cannot guarantee will assist you -

Firstly MPEG4 is NOT the compression/codec used by AVI files and so it appears strange that you (state) -
And the AVI's are:
Video Compression - ffdshow Mpeg 4 Video Decoder
According to what I have read MPEG4 is used for DivX, etc

What are you project properties (file > project properties) BEFORE you drag the clip onto the timeline?

Do you have "Show message when inserting first video clip into timeline" set (in preferences), if so set it on.

What happens when you drag the video clip onto the timeline? Do you get a splash screen advising that the properties aren't the same and asking you do you want to change...?

What are the project properties AFTER you drag the clip onto the timeline.?

You might try using a 3rd-party program to convert the files to MPEG-2 or DV. SUPER is free, and it can probably convert your MPEG-4 file to an MPEG-2, but I don't think it can make an AVI/DV file. Did your camera come with any software? Maybe it's own software can make a DVD compltible MPEG-2 file. (I assume you are trying to make a DVD....?)

If you convert it to MPEG-2, choose a DVD compatible format (i.e. 720x480 @ 29.97 FPS for NTSC, or 720x576@ 25 FPS for PAL).

A lot of people have had trouble with MPEG-4 variations. The more compressed the format, the more likely you are to have trouble! None of these highly-compressed formats are really supposed to be edited or converted. They were only designed to be played-back. They all use lossy compression, so you loose data/quality each time you edit and re-compress the file, or whenever you convert from one lossy format to another lossy format.
Firstly MPEG4 is NOT the compression/codec used by AVI files ...
Actually, AVI is a "wrapper" or "container" format, and it can contain anything from DV to DixX. There is a header in the AVI file that's supposed to tell the software which codec to use. The ideal format is AVI/DV at 13Gb per hour. (This is what you get from a Mini-DV camera.)

True, a digital still camera is not meant for shooting editable video. But since I am saying goodbye to dv tapes (sold my old camcorder) and am waiting for Sony to release their newest hard drive models (DCR-SR) this March, I'm temporarily using the Casio Exlim for shooting videos onto 2GB sd card.

No matter what my project properties are (either avi template or mpeg) when I load and drag the video to timeline it is unrecognizable. The project properties doesn't change before and after that, I don't get any error messages or splash screen.

However converting the avi files with this SUPER software (thanks DVDDoug) works fine. Apparently the Video Studio has some problem with mpeg4 encoded video, but once you get out of this format it recognizes the file just fine (I tried converting to mpeg2 and to DV avi, both were recognized).
