I have tried to create a presentation in DV AVI format but the file get so huge that I run out of free Disc space. We are talking over 40GB file size for a 10 minute long slideshow. Has anyone else experienced this problem?

Here's my thoughts:

1. Is the album set to loop continuously? If so, the capture will act like the Everready Bunny and keep going and going and going.

2. If the album is set to only run through the photos or music or ..., then what are the CAPTURE options that you are using (besides DV AVI)?

Album is set to end at last photo
Capture options were as follows:
High performance
Resize the capture source
Us hardware acceleration
Use the VAC mpeg decoder video
Use currently installed MP3 decoder audio

Are you using one of the mixers?

They also have a loop capability - so even if you set each album to run only once, the mixer could be set to repeat.

Also, check out Nan's comments in http://www.3d-album.com/forum/viewtopic.php?p=9859&highlight=#9859

This is only 1 album and I am not using the mixer. How do you change the compression method that Nan refers to? Maybe that is the problem. I am doing a test with a 79Kb .vexe file and the result is over 2 GB AVI file.

Go to Nan's posting and post a question there about how to change the compression.

Meanwhile, do me a favor and run a test for me. Run the capture using DVD NTSC. If it runs OK, that will isolate your problem to DV AVI. If it also runs for ever, then the problem lies with your album.

BTW, the 79kb .vexe can't be used to determine what the album capture time should be. Much more important is the number of photos (MyPhoto folder) and the animation/timing as determine by the style used. You already said that your slide show is only 10 minutes long, so the CAPTURE time should be somewhere between a half hour and two hours, depending on your hardware (PC speed, video card, hard drive free space, etc.).

The album did capture with no problem in DVD NTSC and the mpg file for the same test album was only 8.33 MB. The total album is 70 photos long but I only captured through 2 of the photos to run the test. The 2 photo test in DV AVI created a 1GB avi file.

DV AVI file has not the 2G file size limitation. DV AVI is big, but not seems to be that big as you described. What is the resolution of your video? If you use NTSC DVD resolution, i.e. 720x480, 1GB file size for just two photos may be way too big than what DV AVI supposed to be. How long is your video? 1GB DV AVI in 720x480 should hold 4 to 5 minute long video.

The original video that I was trying to do was 70 photos. I just ran a test with 3 photos. The resolution is 720 x 480. The test video is 1 minute and 14 seconds long. The AVI file is 2.15 GB. I am using the Wedding #1 style.

LHDREAM,
Did you resolve the problem?

LHDREAM · Posted: Thu Aug 03, 2006 11:19 am Post subject:

No, I did not. I just assume that the DV AVI files are that large and that you would need a mega computer to create them.

I seem to have a problem with the DV AVI Capture also. After multiple tries and the system eventually hanging up a few photos in, I switched from DV AVI to AVI and set the compression to use the Canopus compressor (happens to be on my system from installation of Storm II). File captured and runs fine.
36 photos captured in approx. 2 minutes -- slide show (montage) runs 4 minutes 15 seconds on screen.

Arlen,

Do you still have the above file? You talk about it's length (time), but I was curious as to it's final size in mb or gb.

I said this in another forum topic. Here it is again:

DV-AVI is primarily for editing and/or cataloging purposes. If going directly to Mpeg2, each subsequent edit will result in some quality degradation. If one plans on making multiple versions of the same DVD/file, but with slight changes to each copy (i.e. title, names, music, etc.), then saving to DV-AVI is a consideration if you have the disk storage space. However, in most cases this is unnecessary and redundant. Also, storing DV-AVI files to DVD for library purposes is not practical since only very small files can be stored on single and/or double sided DVD's. This will change when Blue-ray prices come down and it becomes a standard. For now though, this is not an option open to everyone.

Many of you seem to be overlooking what the "final output" of your video project is supposed to be. If your intention is to create a DVD with no further editing required, then capturing as DV-AVI is not the best option, NTSC or PAL MPEG2 is. Otherwise your output can result in the frustration with file sizes many of you are experiencing.

If you are only creating files for playback on your own PC, and, have the disk storage capacity (one of the new Terra-bite drives is best), then DV-AVI may be considered. But even then you may only be able to store 25-100, or less, individual video files on your PC before you run out of space.

When authoring a DVD, the resulting conversion is to MPEG2. If your original file is DV-AVI instead of MPEG2, you will not gain an improvement in quality. However, if during the creation process, you captured to MPEG2 and then re-edited this MPEG2 file several times (perhaps using an NLE editor), before being satisfied with your final result, you may notice a decrease in quality.

Consider your intended audience when it come to final viewing. wmv for broadband 8, 9, or MPEG4, is best for online viewing. There will be little noticable quality degradation when played back on PC unless you use a screen size of 640x480 or larger. For files written to CD for distribution and playback on PC., MPEG2 is just fine, although they will be large files as well. This is why MPEG1 for CD distribution may be an alternative. The file size will be smaller, but the trade-off is loss of quality.

If one tries to distribute DV-AVI files for online viewing or CD distribution, this will only result in outrageously long file loading and/or CD over capacity. Don't do it!

If you remember that DV-AVI is for future file editing only, you won't go wrong.

Michael, welcome back from your most recent trip. Thank you for your comments. I agree with you. But, I'm curious about Arlen's compression.

Arlen, do you still have the above file? You talk about it's length (time), but I was curious as to it's final size in mb or gb.
