I've gotten a couple of questions via e-mail in which folks have created small test VTSs for testing MOBILE encoding that haven't successfully encoded because of the input size. I'm hoping this post can clarify this a little:
By default DVD-RB does not process VTSs smaller than about 50MB. This is because the size is inconsequential and the processing adds time without noticably improving quality. This minimum sizing still holds true for MOBILE encoding as well. If you want to do testing on very small VTSs you must add a line to the REBUILDER.INI's "[Options]" area similar to this:
VTS_MIN_SIZE=1
This will tell DVD-RB to process every VTS that is at lease 1 sector long. Please note, however, that it is recommended that it stay at it's default.
The MOBILE encoder trys to distinguish between "real" video material you want encoded and the transient "junk" often found on a DVD. It does that by ignoring all PGCs that are smaller than about 15 minutes (actually 22500 frames). You can also circumvent that restriction by adding a line to REBUILDER.INI's "[Mobile]" area something like this:
PGC_MINIMUM_FRAMES=1
Every PGC with at least one frame will be processed. Warning: Doing this will instruct DVD-RB to process EVERY SINGLE PGC on the disc regardless of size. That could be A LOT OF PROCESSING. I highly recommend you leave the setting at the default also -- but certainly don't forget to remove it after your testing if you do decide to use it.
If you want to simply test the MOBILE capability without having to encode an entire movie -- I've added a testing capability. If you add a line similar this to the "[Mobile]" area of the REBUILDER.INI file:
FrameLimit=2000
This will encode only the first 2000 frames of each PGC selected. It's good for testing, but DON'T FORGET TO REMOVE IT when you're done testing.
Thanks.
