TMPGenc bitrate/audio questions... |
|
|
I haven't used this software for over a year, and I have no idea what
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

DVD video *must* be 720x480 and either 23.976fps, 29.97fps, or 25fps (and
720x576).
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? |

Incorrect. See http://www.dvddemystified.com/dvdfaq.html
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 |

The following link will answer all your questions about the optimum
settings for TMPGEnc.
http://dvd-hq.info/Compression.html
http://dvd-hq.info/Calculator.html <--- determine the optimum bitrate
for the length of a video.
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. |

Excuse me. I had forgotten about the quarter-res option. Red cheeks galore
