Great to hear Paul! I'll put a thread together based largely on your ffmegX instructions and post it here in the near future. Did you download the latest version of http://www.celt.sunysb.edu/paul/mpeg2enc_HDTV.zip?
It contains a package installer for the library file and a readme with the ffmpegX workflow, it would be great if you can go over it and post any revisions that you see as needed.

I tried to see if there was an easy way to create presets within ffmpegX today, I didn't see anything right off the bat. I can disect ffmpegX a little by control clicking on the ffmpegX icon and using "view package contents". I dislike that the author went out of his way to obscure the program, by protecting the applescripts for example and not showing the commands that are used for conversion.

There is a program, Mediapipe for the mac which is similar to ffmpegx (except it is free and harder to use). Mediapipe is a GUI for UNIX tools but it also shows the entire list of commands that it generates so you can tweek them on your own. FfmpegX is limiting because it deliberately hides these commands.

FfmpegX isn't all bad, it is easy to use and we got it to do what we needed, still I am going to continue working on the droplet which will work without FfmpegX

You can create custom presets in ffmpegX using "file, save preset" menu item.

Can you post those instructions up here as well? That's the link to Apple HDV solutions.

Success!!!!

Using Paul's excellent "how-to" I was able to record an edited clp back to my HD1 using my Mac and the results were great, if not excellent...

Thanks Paul!!!!

II did notice a few minor quirks but I am sure that I can work around them now that I found them...

1) I set the bit rate on ffMpegX to 17000 and I noticed that the transfer bit rate jumped from 13000 to 17500...I guess I can go as high as 19000 so I may try that on the next one...

2)there was a slight delay from the time that DVHSCap started the transfer to the time the HD1 began recording...about 2 seconds...so I will adjust and give it a bit of headway on the begining...

Things that i will work on next...

I used Motion Jpeg A when I did my export to Quicktime...i may use a different codec next time (Pixlet, or Dc30 lossless) to see if I get better results...

All of this for the awesome price of $15 for the shareware fee...too cool...

I am a happy Mac FCP/HD1 user right now...

Cool, Carlos, sounds great!

That is great to hear Carlos! You could try higher bitrates than 19000, there should be some sweet spot between 19000 and 30000 that the camera will accept.

Carlos Salcedo January 20th, 2004 02:51 PM

That's what I was going to try Paul...I figured that it would choke up somewhere...I will do some tests and see where that is...

Thanks again for your efforts...Now I can really have a good workflow with this camera...

Now all I need is a HD capable DVD recorder and player...

Carlos
