Encore "bitrate too high"

[I J Walton]

As just a test i transfered a DV avi to MPEG with TMPGEnc (2 mins long) I used 2 versions, one with VBR (max 8000) and the other with CBR at 8000. Now am i right in thinking that adobe encore DVD can burn with a bitrate of 8000? Because when I go to burn either of the tests (with wav. audio) I get the message "Bitrate is too high". Does anyone know how i can solve this problem? I'm pretty sure that 8000 is not too high

Thanks.

8000 is pretty high. I believe it says in the manual somewhere the bounds for MPEG2 files. Another thing to consider is if you'll ever even notice the difference between a CBR of 8000 and a good VBR encoding with something even less than that as the max. I go max 6000 on VBR settings.

DVD players have a maximum bitrate, DVD must not have a bit-rate that exceeds this maximum otherwise it breaks this standard. (Super-Bit DVDs break the standard) this standard is to ensure that every DVD player can read every DVD at 1x. While you're video may be under the limit, other streams stack into the bitrate, and WAV audio is completly uncompressed, that is what is likely pushing your stream over the maximum bitrate. :P

I have this issue with my DVD player and SVCDs. It can't read standard CDs faster then 4X, so if it meets a stream that is larger then 2600kbps it starts dropping data and frames untill it looks all garbooly.

The max video bitrate for DVD is 9.8Mbits. The max total combined bitrate (audio + subs + video) is 10.08Mbits. You can easily have max video bitrates above 9MBits, just not with PCM audio. Either lower your video bitrate or use some form of compression for your audio such as AC3 or mpeg audio (non PAL DVD players may not support the latter.) There's no reason to use PCM audio if its just a movie soundtrack. All that extra bitrate will benefit your video much more.

@DJ_Izumi: SuperBit DVDs do not violate the DVD standard. The only difference between a SuperBit DVD and your typical DVD is that the SuperBit releases prioritize video and audio quality at the expense of extra features. So with less content they are able to increase the audio and video bitrates, and include additional audio tracks such as DTS. But the disks must always comply with the DVD specification so that they will play on existing hardware.

Well, I stand corrected, I'm sorry then. I hope the 'Blue Laser' DVD developments go well, dispite the fact that it'd involve developing a new DVD standard. It'd be nice to see more data on the disk so things can be more efficent, not to mention it's a chance to add upgrades to the DVD Standard, I imagine room for improvement has been found since 1997. he he.
