First off, let me say hi to everyone, and thank anyone who takes the time to read my question, let alone try to help me find the best answer. I hope this will be a great resource for me in my projects.
On to the point.
I do a lot of helmet cam footage that I need as clear as possible for use in a production DVD. I use the Aiptek PVR recorder, similar to this one …
Because it is convenient, and has as good, or better resolution than my helmet cam…. which is the Bullet Cam model (the higher resolution model)
My problem is this- The PVR records in a .ASF format…. which my editing software does not support (Premier Elements)… So, I have to convert it…
I have been using the Stoik Video Converter 2.1.1, that I found for free on the net here…
It has options to convert into many different formats (several DV.AVI, DivX.AVI, several other .AVI’s, .WMV (in several styles) and uncompressed .AVI)
I have been converting to "AVI for PC Large (640×480, 25fps, Cinepak)" setting, because it is the one that clearly states that it is a higher resolution than the helmet cam or PVR AND is compatible with Permier Elements…. the problem is, THESE FILES ARE BIG… and they take FOREVER to render out…. as in, a 10MB .ASF file is converted to a 1 gig .AVI file… over the course of several hours… which I can’t believe is helping my resolution in any way, as it was a smaller file to BEGIN with….
Can someone please review my equipment listed above, and suggest a conversion program, or method within the one I have, to convert this video to a reasonable sized format, without loss (remember this will be on DVD in the end)…. Or, better yet, a way to just get Premier Elements to accept this format (.ASF), so I don’t have to convert at all.

If you are going for a production DVD as the final output, your best bet is to record your original in a less compressed format to start with. ASF is a distribution format primarily for web-based video, hence highly compressed with poor quality.
As far as the size difference it is a result of the ASF file being so highly compressed to start with. Quality video takes up a lot of space on a hard drive.

Thanks for your thoughtful input.
I already have a DV cam that the helmet cam will plug into. That is what we started using the helmet cam with. But this Aiptek has a lot of advantages to it. It is super small (about the size of a large wallet)- It has better resolution than the helmet cam (which means, at least theoretically, that I should be suffering no image loss)- it is cheaper if it gets trashed (likely given what we are doing with it, and the fact that we already trashed 2 DV cams)- and it is easier to use (just push one button and your rolling/stoped)
This is action stuff, and the subjects don’t like waiting around for the helmet cam to get up and running.
I have no options with that recorder on what format to save to, so .ASF is my only option in that regard.
I will try the option of just renaming the file, that would be ideal. Then I loose no time in conversion, no quality loss, and I need to rename each file anyways. *fingers crossed*
Does all of this make sense to you guys? Using that camera because its resolution beats the HC’s resolution? Or is there some reason I would still be better off using the DV cam? As you know, if I go to .AVI from the DV we are talking EVEN MORE space (in the order of 1 gig per 5 minutes)… that is something I hope to avoid, as that footage is low res anyways.
I really appreciate the input guys. I hope to learn a lot from this forum, and when I do, I’ll be sure to share it here too.

well, just renaming it doesn’t cut it…. then Premier recognizes it in the folder, but it won’t load into the program.

*sigh*….. well, it turns out that the NEW version of Adobe Premier Elements accepts that file type for input…. so, now I have to consider just buying that, as it seems the most reasonable solution….

I would try using Virtual dub (another free program). Virtual dub allows you A LOT more control.
and downloading a codec pack. (Like the k-lite codec pack)
Virtual dub gives you more options to format into. I found a tutorial to do this:
You could then at least convert into XVid (where you can set higher quality settings). I’ve found that the cinepak codec is pretty crappy on the size vs. quality (when making a video last time). I had the same problems on my old computer about space (and I still do on this laptop!!!). I hope this helps a bit.
You can tweak the settings for the codec. If you need any more help using virtual dub, I’ve used it quite a bit. and have a look at
Lots of GREAT resources for file conversions.

I just saw this note at the bottom:
I can’t open ASF files. Be sure to use Virtualdub 1.3c cause newer versions of Virtualdub do not support ASF and be sure to install the ASF Codecs ( MP43 (Microsoft High-Speed MPEG-4 V3) ).
You can get that at this website:
I hope that helps!
