How Does PowerDirector Handle Saving Assets

I’ve got what I think is a simple question. I checked the forum but did not have any luck finding an answer.

Say I’m working on a project. I bring three or four clips into the Media Room. The clips are various lengths and file sizes, let’s say 10min @ 50MB, 25 min @ 200MB, 40 min @ 350MB and 1 hour @ 800MB. I put each in the timeline and perform my edits on each one individually.

This is my question. When I get ready to either “Produce” or “Create Disc”, how does PD handle the original four original files in the media room. Do they reside in the Media Room in their original size?, or Is it only the edited clips in the timeline that are sent to the “Produce” or “Create Disc” function leaving the original files stored in the Media Room?

I’m trying to get my arms around how big some of my projects are after all the edits have been performed. I had one project that came in at 15GB. This was after I had edited the original clips into smaller clips. It seemed to me the end file size should have been smaller.

Any insight would be greatly appreciated.

Thanks,

Hi Teeman1 -

To produce or burn to disc, PDR uses only the media in your timelines. BTW, your original media is not actually "stored" in the Media Library". It's right where you left it. PDR just remembers the file path.

The file size of the produced project cannot be estimated simply by looking at the file sizes of the original media. It basically comes down to a few main factors:


  1. Duration of the project

  2. Format/profile slected for production/disc creation

  3. Video bitrate

Tony, thanks a lot for clearing this up for me. This particular project will be upload to a DVD Replication Facility for mastering and replication. I just wanted to make sure there would not be any surprises.

Hi again -

This isn't directly related to your DVD production but, as an illustration of the above, I took a 720p 60fps clip, trimmed it to 1 minute and produced it to a variety of different H.264 MP4 profiles.

You can see that resolution & framerate have minimal impact on file size but video bitrate does!



For DVD, the VBR will be about 8Mbps so file sizes will be much smaller.

Thanks Again Tony.

I have been using as my standard 1920x1080 at 24 FPS and a 16MB bitrate. It is very clear to me the impact that bitrate has.

This particular documentary project is going to interesting as it will have 4 different DVD's produced. Each one is close to 1 hour 50 minutes.

Again, thanks for your help.

Best,
