Canon HV20 to HD-DVD on DVD+R, how to select higher bitrate?

Post by germandebbie »

I captured the HDV video from my Canon HV20. Using the trial
version of Video Studio 11, I burned it to a HD-DVD on a regular
DVD+R.

Two folders were created: ADV_OBJ and HVDVD_TS

However, the 20 minutes of HDV video only resulted in a 2.88GB
HVDVD_TS folder. It seems a bit small to me. I looked up and down
in VideoStudio but didn't seen any option for selecting the bitrate.
(other than the HD standard 15GB or 30GB option)

Any advice apprecieted! :)

Sorry I don't have time for more step by step explanation (your workflow method needs to be changed in order to produce a better video) but try this.
Start a new project with an empty timeline.
Go to "Share -> Create Disk".
In the create disk module use the bottom selector to select HD-DVD -15/30gig project.
Insert your captured hd.mpg file (the original captured file).
Right click on the video and select "Properties", write them down.
Click on the Gear Icon "Change Mpeg Properties -> Customize" and set all the project settings to EQUAL your source video. Make sure "Do Not Convert etc" is checked on under the Gear Icon.
When you burn the hd-dvd the process should go very fast, the original video should not be re-encoded.
This will keep the bit-rate to the original which is 1440x1080_CBR@25000kbs Upper field first 16:9, mpeg audio @384kbs.

THANKS! I'll try with your instructions.

Just one quick question, is there any difference between the 15G/30G
selection?

Not that I can tell.
Using VS the workflow with HighDef is the same as standard definition except for the technical video & audio parameters so using the tutorials on this forum can be a great help. It's really the same workflow, just bigger files and different parameters, but the video editing/burning theory is the same.
Your original source video was re-encoded to the project settings that were used in the Burning Module (different from the VS timeline). The burning module is pretty much a separate module. When you go from the timeline with a video in the timeline into the burning module (create disk) it's the VS Project you see in the burning module, not the actual video file (yes, confusing).
So, what I posted for you to do is bypass carrying the video from the VS timeline into the burning module. You don't usually want to use that method.

I think your original video was re-encoded to a lower bit rate and possibly encoded with incorrect fielding settings (maybe lower field first or frame based when it should be Upper Field First).
