MF5 Encoding - Stuck on 4200 Variable Bit Rate

Hello,
Working in the STANDARD Definition / STANDARD Dvd creation screen:

Anyone experiencing problems with the video in MF5 switching the "Project Properties" or Exporting Mpeg properties to "Constant Bit Rate" will give you much better results.

So exporting at 6000 to 8000 Constant Video Bit Rate with Dolby Audio will give you excellent results. Even at single pass mode.

On my system I can't encode at variable bit rate higher than 4200.
I set the encoder to 8000 and the resulant file is 4200.
Anything I set above 4200 in the compression tab gets encoded to 4200.
Going below 4200 variable is working.

Unless your using 2-pass encoding Constant Bit-Rate in my opinion yields better results anyway for a single-pass encoded dv to mpeg file.

So, if your dvd aren't that great change the project properties to Constant at 7000 to 8000 dolby audio. No comparision between the 2 settings.

Hi MD,

yes, there seems to be a problem with the VBR settings in MF5!
They seem to jump back to some default range after setting them higher... need to experiment some more to find out when/why this happens. I'm using the trial version until I see certain updates appear.

I just checked the rendered menu that used my template: PAL 4:3, 2-pass VBR 8800max/7800avg/7300min, intra DC precision 10, Dolby 448.
The DMF5 menu vob file has the 8800 value in its header, but the data is never higher than about 4200 bitrate!

I encoded the video (not menu) with Canopus PCE, so DMF5 luckily doesn't encode the already compliant data (which does use the selected max/avg/min bitrates).

Hey, check this out.

Encode the video at Constant bit-rate of 6000 to 9800 Dobly etc.
I used 90% Compression.
My dv.avi to mpeg2 file looks superb.
The mpeg2 file is really nicely encoded.

I can't get the audio to preview in the preview menu. Just repaired & rebooted the machine.
Still no audio preview.

Try constant bit-rate.

Just to let you know, Ulead is awared of the VBR encoder issue and is checking it now.

Best regards,
H.T.

HT,
I've sent them all the bugs I've found so far.
The latest being trying the "Edit Disk".
When I use a dvd-ram or dvd-rw recorded in the -VR mode:

The "Slider" Control directly below the Thumbwheel for naviagation
plays the video in the "Forward" direction when trying to reverse.
The Thumbwheel works and sliding in the forward direction works but
on my machine the reversing plays the video in the forward direction.

I reported that last night to an admin person.
I imagine it will also do that with different format disks.

I have a question. I'm making dvd-ram disks as data disks formatted for packet-writing in the udf format.
If I format the disk from the launcher screen it defaults to the UDF 1.5 file system.
If I right-click on the drive from explorer and select "Ulead data-add format disk" it was defaulting to UDF 2 or higher.
Do you know if that matters or is the UDF 1.5 file the standard so other computers can read the disk also.
