I want to up my game in the DVD Authoring stakes. I'm focusing on finishing documentaries and indie films and I want to be able to provide my clients with the best possible dvd that they can afford. As it's the indie side of the market I'm not going to jump straight in and by the cinemacraft plug-in. That leaves me with Bitvice.
I've downloaded the latest demo (2.3) and I've been doing comparative tests with compressor. Problem is I'm getting "video bitrate too high" errors in DVD SP when I build my DVD's to compare the encodes. The first encode I did worked but every other test since doesn't. Here's a look at my settings, these two images are the last two encodes I did which DVDSP is rejecting for the above reasons.
You'll see that first I pushed the average bitrate up to 6.5 and the second attempt was using all the default settings in Bitvice except the "intraDC" setting which I upped to 9 from the default 8. (This was a recommendation from this forum.)
Apart from this specific problem, from what I've seen, I can't tell any difference?
I'm encoding a SD 10bit uncompressed image that was shot on EX.
Thanks for the reply. Perhaps it's a restriction with the Demo, but I can only save audio as AIF?? I'm going to do test right now to see what happens if I try to encode without the audio file! Stand-by.
Thanks Eric, once I deleted the AIF file from the DVDSP build it encoded just fine!
I see from your posts that you're the Bitvice champion around here. Can you recommend settings or a workflow that will allow me to create the 'superior' rendering capability of Bitvice vs Comressor?
I believe in Bitvice since it one of the few Mac encoders out there - and its a good price. I have yet to try the Cinemacraft plug-in but I''ve used the PC version for years now.
You have bandwidth limits that need to be considered in DVD. 9.8 for video and 10.08 for audio and video. Since all encoder will sometime spike over the limits you set, along with your uncompressed audio (which takes up 1.5 mb/s of space) you certainly went over that limit.
8-9 mb/s is too high. There isn't a DVD compressionist in the world who would tell you to crank up the max bitrate settings to the max. Keep your bitrate settings at a conservative level and always check your bitrates with a bitrate viewer afterwards. Use uncompressed audio but only if you take that 10.8 limit into consideration. Always use a bitrate calculator before you encode.
I dont' use Compressor since its frankly a terrible encoder at lower bitrates. Compare the 2 by doing a short test at VBR 3mb/s with some moderately fast movement in the source. Not that you'll be doing VBR @ 3-4mb/s alot but it shows you how much better Bitvice can be a lower bitrates. If a client comes to you and insists they need 4 hours on a DL disc, you can now tell them - "OK...I can do that" :)
