What does TMPGenc do?
TMPGEnc converts *.AVI file to MPEG1, the format which is
used in VideoCD. Using variety of option in TMPGEnc, you can
compress your video file in high quality.
TMPGEnc enables us adjust bitrate, quantize matrix, GOP structure,
Interlace and many other parameter so that you can create
most appropriate movie file depends on your purpose.
TMPGenc FAQ's
What is MPEG?
MPEG is a movie format which is defined by MPEG(Motion Picture
coding Experts Group) of ISO. This format consist of "video",
"audio" and "video - audio mixed".
What type of MPEG stream is available?
MPEG-Video stream This is video part stream. The file extension
would be m1v, m2v, mpv, vbs etc.
MPEG-Audio stream This is audio part stream. The file extension
would be mp1, mp2, mp3, mpa, abs etc.
MPEG-System stream This is multiplex of MPEG-Video stream
and MPEG-Audio stream in one stream. The file extension is
mpg, m2p etc.
What is I picture P, B picture?
I picture This is independent picture which completes compression
inside frame. The frame data can be played independently.
P picture This refers to previous I, P picture to extract
difference, then compressed The compression is higher than
I picture.
B picture This refers to both previous and next I, P picture
to extract difference, then compressed The compression is
higher than P picture.
What is bitrate?
Bitrate means the number of bit which go through the stream
per 1 sec. Stream means the MPEG file.
Generally, compression is described by bitrate in MPEG. The
higher bitrate, the higher quality and lower compression,
larger file size.
If the bitrate is same at any part on a single stream, it
is called as CBR (Constant Bit Rate). Although MPEG is usually
encoded in CBR, TMPGEnc is supporting both CBR and VBR(Variable
Bit Rate). In VBR, the bitrate can be different depends on
the part of stream.
How can we calculate the actual size of MPEG file which will
be crated?
If you choose CBR, The following equation can be used to calculate.
"2048/2018" stands for bitrate of system stream.
Filesize (Kb) = (Video+Audio) x (2048/2018) x sec/8
E.g. Video is 1150Kbps, audio is 224Kbps, 15 sec MPEG file
would be "(1150+224) x (2048/2018) x 15/8" = 2614KB
An error occurred when playing MPEG file I have made.
If you playing an MPEG file whose windows size is large with
Windows Media Player, an error occurred.
We have verified that most PC can play MPEG1 file which is
smaller than 720x480 properly.
Can not play MPEG-2 file I have made.
MPEG-2 file can not be played only by Windows. You need to
install a DVD software such as WinDVD, PowerDVD, then you
can play MPEG-2 file with Windows Media Player.
MPEG movie is not shown properly at full screen.
Here is recommended aspect ratio for each size of movie.
Size recommended aspect ratio
320x240 1:1 (VGA)
352x240 (Video-CD) 4:3 NTSC
640x480 1:1 (VGA)
720x480 (DV, DVD) 4:3 NTSC
None of the above Try 1:1 (VGA) first.
It takes more time than I expected, to seek MPEG file to
display.
MPEG-2 file can not be played only by Windows. You need to
install a DVD software such as WinDVD or PowerDVD, then Windows
Media Player can play MPEG-2 file.
Can we use MPEG-Audio Layer3(MP3) for audio part?
TMPGEnc does not include MP3 encoder. You can use external
encoder such as SCMPX, or you can create MP3 file for TMPG's
audio source.
As far as I know, a MPEG file whose audio is MP3 can be played
only by Xing MPEG Player.
Can we cut / paste MPEG file?
Go to file menu > "MPEG tool" to merge MPEG files
into a MPEG file. You can also cut MPEG file there.
However, according to MPEG structure, MPEG file is not always
cut by frame, some time edited by GOP.
When I tried to merge MPEG files with "MPEG tool",
an error occurred that it is not compatible. How is TMPGEnc
verifying compatibility of MPEG files?
The following parameter is verified.
Video parameter Condition
Windows size must be same to be compatible
Frame rate must be same to be compatible
Aspect ratio must be same to be compatible
Bitrate If bitrate is different, it will be outputted as VBR.
VBV buffer size The most largest VBV buffer size among merged
MPEG files will be outputted.
[2] TMPGEnc in General
TMPGEnc seems to be slow to encode.
The quality of movie has much higher priority than encoding
time on TMPGEnc. Also, MMX is not fully supported yet.
MMX, SSE full support will be done in the near future.
Is there any clue for compression time?
If you have Single CPU + MMXenabled + 352 x 240, the following
equation.
(2800/,b,o,t speed(MHz) x source length(sec) = brief encoding
time
If you are using filter, it will be more slower.
Encoding is aborted with stream writing error.
Either temporal HDD or target HDD for MPEG out put is too
small to store the MPEG data.
Go to Menu > Option > Environmental setting to set folder
for temporary file.
MPEG file I made is larger than source file.
TMPGEnc adjusts to longer file from either video or audio,
then larger file can be made.
Version Bata 10m or later can specify encoding area to solve
this matter.
Which is preview before encoding or after encoding?
As far as it is before encoding, the preview is also the one
before the encoding. In the case of AVI, preview is always
the one before encoding.
Despite that the frame rate of a AVI file was 30fps, it was
automatically converted to 29.97fps in MPEG.
TMPGEnc automatically choose closest, higher frame rate. If
you do not like the framerate which is automatically chosen,
please select the framerate you want.
I would like to know the order of filter.
Convert to 24fps > Ghost erase> Noise erase > Sharpen
edge > Color adjust > Disable Interlace > Detect
scene change > Clipping > Enlarge/Reduce > Encode
Does TMPGEnc read referred AVI file made by DVRaptor or IODATA
GV-DVC/PCI ?
TMPGEnc can read all the AVI file which can be read by applications
supporting Video For Windows.
Does TMPGEnc read OpenDML(AVI2) format?
TMPGEnc supports OpenDML file format, so it is able to read
non compressed AVI file which is larger than 4GB, however,
Type-1 DV format is not supported.
TMPGEnc can not read AVI file with DV format.
The file is probably Type-1 DV format. The format is not supported
by TMPGEnc. Type-1format has different structure from AVI
format. TMPGEnc can not read the format since TMPGEnc does
not support DirectShow.
To solve this matter, try to save the captured or edited file
as Type-2 DV format, however, there are still chance not to
be able to read the file if you are using general IEEE1394
board without codec for VFW.
When I open the property of a MPEG made by TMPGEnc, audio
is different from I specified at encoding option.
Are you using "mp3info" to display MPEG file's property?
As far as we know, mp3info does not seem to support system
stream format.
mp3info detects wrong since a part of system stream is similar
to MPEG-Audio file header.
If you are encoding audio only, correct bitrate will appear.
