I convert my downloaded anime episodes with TMPGenc. However, this one episode that was around 170 megs, converted to around 600 megs, while the rest was around 200. I do not know why this is happening please help me.
The input size has nothing to do with the output size, the output size is directly related to the length of the input file and the bitrate used, so takeing this in mind if the file is still to big the only thing I can think of is if you are doing a vcd in the settings under "System" change it to "video-cd non-standard".......
I have a question about 2 pass VBR settings. I take home movies on my canon DV camera which I then edit in an editor and produces a nice AVI file. I then drag this file into TMPGencoder and make SVCD movies (NTSC). I have had my settings set to average bitrate 2520, max bit rate 2520 and minimum to 300.
I have had someone comment to me that my minimum bit rate is set too low. My question to you is what is a fairly averag setting all of you use out there for minimum. I mean I usually try to fit my DV movies (33 minutes) on one 700 mb CDR and works just fine. If I set the minimum to let's say, 1100, does this change the size of the file too much and does the CD become non SVCD mPEG compatibel?
I wouldn"t say that you minimum is really too low but all your settings are off, you sort of defeat the purpose of encodeing to VBR if your average and maximum are the same, that means that your file will be closer to a CBR stream than a VBR stream,that is why you are only getting 33 minutes on a CD-r, you can get much better quality and get up to 45 minutes or more on a cd-r if you tried settings something like 500kbs minimum 2250 average and 5000kbs max..With these settings you will have a true VBR mpeg stream with a higher max bitrate the average is about the same and the minimum..I used these settings last night on a 704 by 480 file and got 43 minutes and the file was 707mb so I could still have fit another 75mb on this file(you can get 795mb on a 80 min cd-r) and the file looks great...These numbers are just an example of worked good for me but a VBR stream is supposed to be encoded with parameters simular to this.......
Personnally I prefer CQ than 2-pass VBR... thanks to ASHY I use Max. 4000, min. 1800 and CQ 65... I have very great results and at least 60 minutes with it!
Thanks for the reply. However, one very important question. If I am not mistaken, True SVCD has a maximum of 2520 kb. Does this not mean that if I put the maximum at 5000 kb and at times it goes that high, my Pioneer player can't read it?
maybe you should check on www.vcdhelp.com for the compatibility list but lots of DVD players are able to read what we could call XSVCD... mine (a JVC) read them perfectly...
Your right that certain players may not read the higher bitrate and could choke your player, so check out VCDhelp to see ehat it can handle.
As far as encoding goes you will find, as do many of the others on this BBS, that the CQ method will yeild superior results to the 2 pass method in most cases.
Regarding the chosen bitrate settings as Nico has pointed out, why the minimum bitrate of 1800 kb/s?
This is because due to extensive testing with various settings and different movies I came to the conclusion that 1800 is the minimum setting possible when encoding to MPEG2 to prevent the dreaded macro blocks.
Any lower and macro blocks begin to appear in normal scenes and using this bitrate prevents this.
With the quality setting at 65% it seems to be enough to keep the bitrate at a reasonably high enough level and allow TMPG to adjust the bitrate high enough to compensate for faster action scenes without introducing blockiness and produce a small enough file size to allow most movies to fit on 2 disks.
Also in my opinion it is better to use the standard 480x480 resolution for SVCD rather than 704x480 0r 720x480.
Why? Because I have found that the difference in picture quality of the two resolutions when viewed on a standard TV is not that great or noticable and seeing as higher resolutions need more bitrate, it is better to use that valuble bitrate to improve the picture quality of a 480x480 image.
By this I mean I would rather give up a little less and hardly noticible sharpness rather than run out of bitrate because of the higher resolution on high action scenes and thus end up with horrible macro blocks.
These settings weren't just pulled out of a hat, but were eventually arrived upon after many tests with both TMPG and CCE and the settings are true for both these encoders.
So in conclusion I would say CQ is the way to go for improved image vs filesize quality.
Thanks for all the wonderful info. One last comment though. My old Pioneer 343 plays anything I throw at it. SVCD XSVCD DVD-R etc. I see no problem there. However, the point of filming home movies is so I can supply the rest of my family in Europe (I'm in the US) with acceptable formats they can play. I feel that most of them can play the better quality, however, some are having problem with higher bitrates.
Now, If I use CQ and set the high to be 2520 and the low to be 1800 and then Quality to 100%. Will this yield a good quality flick that will fit on a 700 MB CDR MPEG2...(about 30 minutes of video).. or is that set too high?
P>S I guess I can test my way but I don't have a finsihed edited 22 gig avi file now to convert... :-(
If you are trying to keep your files totally compliant so they will play on the biggest variety of dvd players then the 1800min and 2520max 100 quality would be the best bet but if you lower the quality level to say 85 then you will be able to fit more on a cd-r and not loose any noticeable quality...I like useing the higher resolutions for movies that have a lot of action but you do need to raise the bitrate a bit to keep the same quality...
If you only intend to put 30 mins of video on to a disk then you may as well stick with CBR and the standard bitrate as it's pointless going any lower with the bitrate because 30 mins will easily fit on to an 800mb disk at this bitrate. It may even be possible to use max resolution with this bitrate and still fit it on to an 800mb disk.
In a way. Just click stop when you desire to pause then don't click ok in the confirmation box. Put your PC into hibernation. When you restart your PC just cancel the abort and TMPG will continue encoding.
This is a plugin QuickTime reader for
the TMPGEnc mpeg encoder. You just copy this file into
TMPGEnc's folder and you should then be able to read
any QuickTime movie.
Dear Group,
Am about to order a DVD writer and am currently trying different TMPGENC settings to create MPEG2 from my AVI files. I have found some very helpfull hints in this group but have been unable to remove the blocky or pixelated artefacts from the edges of objects during motion. I have no idea what this will look like on the 32" TV but is clearly noticeable on my 17" monitor. My source is a Sony DV camera.
So far I have tried:
Resolution 720 x 576 and:
a) 2 pass VBR, 8000 max, 3500 min, 6200 average with high quality motion search, DC component precision-10 bits, VBV buffer to auto
or
b) CQ VBR, quality setting 62
I can't see much difference between either method although b) seems to be faster.
Those jagged edges are most likely Interlace lines and shouldn"t show up very much on your Interlaced TV but do show up on a Progressive Monitor, but if you want to get rid of then so they won"t show up on either then try Useing the De-interlace filter in the advanced tab, There are about 25 different filters to choose from so what I do is move the slider till you get to a frame were it looks really noticeable then just go through the filters till you find the best looking one.......
I wish there is option in TMPGEnc shutdown computer after
it finishes editing (shut down when done).
In FlashFXP ftp client has option to log out from ftp sites
after trasfer is complete and then shutdown computer, same kind
feature would be nice to tmpgenc too because video editing takes
usually long time and it would be nice to leave computer/tmpgenc running
at night and go sleep and morning everything is done and computer would
be turned off too automaticly.
Instead of pressing "Start" button, go to "File"->"Output to file"->"MPEG file" then select file name and then when it starts you will have under the progress bar a chack box for shutting down the computer when it finnishes encoding.
Multilanguage MPEG support in one of the next versions!!!
I hope tmpgenc becomes multilanguage mpeg support. for all movies I ripped in two languages I muste use the (free) bbmpeg encoder. Hope tmpgenc can doo this yob in future, too!!!

Try messing around with the deinterlace under advanced settings it worked for me preview each during jummpy section of movie this also adds alot of time to the process but it worked for me.
Did you read the readme file that came with the templates?
It explains how much movie you can fit on to 2 disks and what the templates are for.
In the template folder there are XVCD templates in the same place as the SVCD templates.
With Tmpgenc useing the CQ method with a 704 by 480 resolution and a minimum of 500kbs and a max of 5000kbs and quality of 85 i can get close to 50 minutes on a cd-r with fairly good quality.....
Excuse me again, but I'm still working on Queen of the Dead... I ran the file thru Virtual Dub, extracted a .wav file, and then used the avi for the video source and the wav for the audio source. TMPG encoded half of it and then gave me a "write error" message 45% of the way thru,
I checked the mpg file that was produced and it looks good. No pixels. Now I need to get past that spot where the "write error" message appeared... Can I use MPEG tools and edit out a minute or so of bad file? Do you think that may help?
Easiest would have been to make a note of the frame number where the error occurred and then encoding from the next frame on via selecting the source tick box (double click to enter parameters) from the advanced tab.
If you did not make a note you can always load the file into Virtualdub, go to the end and make a note of the frame number that way.
