TMPGenc bitrate/audio questions...
settings I used to use! Please help me choose the best options... I'm shooting both indoor and out with an XL1, and I'm burning the movies to DVD... 1. Often, I have about 2hrs (slightly less of footage) - I seem to rememer not using the 720x480, but going for a lower res to produce "less choppy" but lower res video. I'm pretty sure that I was unhappy with 2 hrs at 720x with PCM audio since each frame looked good, but the overall effect was choppy. 2. I also will occasionally only use 1 hr of footage, and can't remeber what settings at all. For each of these - what are my best options regarding resolution, audio (PCM vs. MPEG2 - CAN I EVEN TELL THE DIFFERENCE?), and duration? Also, do I just use the default interlace and field setting B options. How about noise reduction? And what is my least acceptable bitrate for each resolution for good results... Thanks. -Steve On 31/8/05 1:02 PM, "Steve" <srjm72***@frontiernet.net> wrote: DVD video *must* be 720x480 and either 23.976fps, 29.97fps, or 25fps (and> I'm > shooting both indoor and out with an XL1, and I'm burning the movies to > DVD... > > 1.

Anything else is not within spec and may be rejected by players. You really shouldn't be having problems compressing DV video to MPEG-2 - you may be seeing stuttering on playback on your computer, but it shouldn't happen on dediated hardware. What are your specs?

Allowable picture resolutions are: MPEG-2, 525/60 (NTSC): 720x480, 704x480, 352x480, 352x240 MPEG-2, 625/50 (PAL): 720x576, 704x576, 352x576, 352x288 MPEG-1, 525/60 (NTSC): 352x240 MPEG-1, 625/50 (PAL): 352x288

I suggest you check them out them as IMO they are required reading. Remember, a single layered DVDR (DVD5) was only designed to store 60 minutes of DVD footage at full DVD quality. Putting any more on the disc will result in a drop in quality. Of course, how much of a quality drop is dependent on a number of factors. Unless the audio is something special (ie. a concert, music) then there's no real reason to use PCM (uncompressed audio). I would recommend compressing your audio into the AC3 format (224 kbit/sec should be enough for most cases but you can go as high as 448 kbit/sec if you want high quality compression). A licensed AC3 encoder costs money but free versions are available (search for BeSweet). Be aware that some people have reported playback problems with DVDs that use the free versions of the AC3 encoder. As you're using a high quality video camera I would recommend using the FULL DV resolution, don't use any the half DV resolutions. There is no need to de-interlace your footage if the final destination is a DVD to be viewed on a television. Even if you want to view your DVDs on a computer, you still don't have to deinterlace as most software DVD players (ie. WinDVD, PowerDVD) have built in deinterlacer filters. I can't commment on what noise reduction filters you should use but be aware that using most filters in TMPGEnc slows down the encode time considerably.
