I am a novice at video conversion so please bear with me.
I attempted to convert an Mpeg file to Mpeg2 for writing to a DVD. Movie is 2 hours long, encoding estimated time of 24 hours to convert! is this normal? Then the conversion stalled out at aprox 11hours.
File was partially converted but has no audio. I picked mpeg system as the option.
I'm running XP Home on a 2.8Ghz P4 w/512 PC2700 ram.
What format is your original mpeg? Depending on the format (resolution, fps, etc) you might be able to burn that to DVD using the header tricks. You are only going to degrade the quality by encoding it again into a mpeg format.
I installed TMPGEnc before I installed .Net. Now the VFAPI Plugin section says "The file can not be loaded". I've done a search for it and it's there, so what do I need to do so it sees it?
TMPG has a bug with some files where for some reason it will read the time header information in the AVI and multiply it by 2-3 times.
You can solve this by using the source range function and just select the start and end points of the movie.
Would be great if Ashy or Minion has a minute to offer some advice on this!
I have a VERY high quality AVI file I am trying to encode for authoring to DVD, which contains several high motion scenes. I have just started using CQ encoding, have been using 2-pass VBR for about a year now.
However, I am running into a little trouble. TMPGEnc Plus does not seem to be enforcing the max bitrate I specify "very hard" with CQ encoding. Perhaps because I have the quality slider up to 100%. (?)
With an audio track of 448kbps bitrate, my theoretical max for video is 9341kbps.
========
My problem is two-fold - TMPGEnc+ isn't keeping the bitrate below 9341 with 9341 set as max (it spikes up as high as 12000!), so the test DVD's with the audio track present stutter on the high motion scenes, presumably due to exceeding bitrate limit - this happens on encodes with 9341 set as max, and I think also with 9000. One encoding pass I made with 8000 set as the max DID keep the bitrates from spiking above 9300-9500 in the high motion parts of the video, and no stutter occurs. But then there are a lot of macro blocks visible in the high-motion scenes.
I have been using DVDLab 1.3.1's Bitrate Viewer to parse the encoded .m2v streams, as a sort of benchmark way to see where bitrates are getting too high. It's odd that it reports a "peak" lower than many of the spikes you can hover over in the graph and see what the bitrate is at that point.
I do have the Soften block noise option enabled in the GOP structure tab, with the default 35/35 set. If I understand the purpose of this option, it smooths macro blocks when the bitrate is right at the limit.
I've also been manipulating the GOP structure in attempt to keep the quality high - although I've normally used 1/4/1 or 1/5/2, the overall quality of the encoded video was a LOT higher with GOP sizes like 1/4/0, 1/2/1, 1/2/0, and 1/1/1. (I did also try 1/14/0 and 1/8/0 but didn't like the grainy/noisy effects). 1/2/0 was really high quality but searching the dvd (FF/REW) looked really bad. 1/1/1 is what I'm using now. I didn't want to use any b-frames but it does seem to make a big difference "searching". It seems to be counteracted by having an I-frame every 4 frames, the quality stays up really high.
===========
Maybe I am just going about this wrong - if I have the CQ slider at 100%, is it forcing TMPGEnc to exceed the max bitrate I have specified?
Typically the encode projects have had settings like this:
GOP size: 1/1/1 (0 picture spoilage for both P and B frames)
Scene Detect: OFF (not really needed since we will get an I-frame every 4 frames anyway)
closed GOP: no
Output interval of seq header: 1
max GOP size: 18 (though at 1/1/1 this is moot)
Since I obviously need to keep the max bitrate set to as close to the max as possible for best high-motion performance (8000 isn't enough!), would reducing the CQ level below 100% and keeping the max bitrate at 9000 or 9341 allow me to control those spikes/peaks (keep them at or below 9341), preserving the quality of the high-motion scenes? Or would doing that (reducing CQ level below 100%) just generally reduce the encoding quality across the board (maybe this could be counteracted by raising the minimum bitrate, for benefit of normal parts of the video).
In a nutshell, is there any way to make TMPGEnc+ ENFORCE the max bitrate you specify when doing CQ encoding?
Thanks for any tips or advice that anyone can offer.
Or could it be that because I am using such a small GOP structure (1/1/1), that the high frequency of I-frames is a big part of why the bitrate is so high? Using 1/2/1 would reduce the bitrate some, wouldn't it? (and not affect quality too bad).
I think I was also trying to reduce the GOP structure in attempt to get the file size up. Having such a high quality source it just didn't seem right that the encoded m2v files were coming out around 3200-3400MB with larger GOP sizes. It just struck me that somewhere, quality is being lost. (the "all I-frames" xfer from source I did for frame searching, for scene cut and audio matching purposes came out to around 5300MB).
Alright well I guess I'm just talking to myself out loud here.
Turns out that 9000 was OK as a max bitrate, I must have just gotten a bad test burn on that one where it stuttered. Either that or my memory failed and I had actually watched a test burn of one with 9341 as the max bitrate and that little bit was enough to cause a bitrate overflow to the VBV buffer during the high-motion scenes/bitrate spikes.
Also as it turns out there was some block noise in the source video during these high-motion scenes.
At any rate, solved my own problem. I also raised the minimum bitrate up to just about 250kbps below the (2-pass VBR-type) calculated avg. bitrate (up to 5600 from 4000) and that improved quality in the darker/low-motion scenes as well.

Anyone? I'm having the same problem, using a DV-sourced AVI file and trying to generate a VCD-compliant MPEG1 file. I've done this dozens of times before, but this time it doesn't work. Note one major change to my system: I recently upgraded to Windows XP, and did a fresh install of TMPGEnc.
Any clues? The MPEG1 encodes are superfast, but all frames of video are black.
OK, I found the solution on another message board. This worked for me:
Try this ...Go to "Options" to "Enviromental settings" to "Vfapi Plugins" and raise the Priority of the "Direct Show Multi-media File Reader" to "2", This should Make it so there is an Image the next time you encode the File...If you do not see any Video in the TMPGEnc Preview Screen which encodeing then there will not be any Video in the Mpeg file....Cheers
When I choose an avi file (the video file) for encoding in TMPEGEnc, TMPEGEnc tells me that the file cannot open or is unsupported. I find that kind of bizarre because the problems I usually have are with opening the audio part (haven't that problem solved either up to now, so if anyone can help me there, thanks in advance). Can anyone help me?
I've corrected my problem. What os are you using? Fortunately I'm using XP and I can restore to an earlier time. I had cleaned up my hardrive earlier this month by removing software that I no longer used. I must have removed a file that is shared by TMPGenc. Restoring my computer to March 1 solved the problem.
i captured a movie in 3450000 bps (3x VCD). TMPGEnc says that it
has 167332 frames. then TMPGEnc says that the video only file
(.m1v) has 167158 frames and the audio only file (.mp2) has 167309
frames.
i re-encoded the movie by using TMPGEnc, VCD PAL settings (same as
source). it produces an mpg file with 167332 frames which its
video has 167332 frames and its audio has 167327 frames. please
describe what all of this mean.
maybe the original mpg file has some frames which is not
recognized by TMPGEnc and it removes them when it splits the
movie? both video frames and audio frames?
how the video file gets 167332 frames long while the original one
has had only 167158 frames? maybe TMPGEnc doesn't omit
unrecognized frames when re-encodes the movie while it does when
splits it? if so why the audio file has lost 5 frames?
what can i do to make the original video and audio files the same
frames long?
there's an option in TMPGEnc which says that "Do not frame rate
conversion". i expect when i use this option, TMPGEnc don't
convert frame rate even if it differs from standard. for example
my video is not exactly 25fps during the movie because of frame
lost. i want TMPGEnc just reduce bitrate and doesn't change
anything else, otherwise video and audio get out of sync and since
this is not gradual lose of frames i can't correct it later by
using a sound editor or anything else. the only way is that
TMPGEnc doesn't change it.
what can i do? do u know a workaround?
do u know any utility to do such a function for me?
I have recently converted a bunch of AVI's to MPEG2 using TMPGenc and when I view these in AVICodec the Audio column (a.1 codec name) says "Unknown [0xc0]". They play all right in Windows Media Player....!!
The Avi's I converted to MPG2 using other app's are listed in AVICodec as "MPEG-1 Audio Layer 2 [0xc0]".
What's up with that...? Is there a setting I should check in TMPGenc before I 'Output to File - MPEG'
I have a defective VCD(mpeg1) and I want to cut the defective part out, but TMPG cannot go through the defective part.
Every cut before the defective part works fine, but I can't make any cut after the defective part.
Someone can help?
There is a program called MME.EXE which is located inside a folder of an MPEG2 codec for TMPG.
You can download the codec below and the program is inside.
If that doesn't work then MPEG2VCR should work as it's quite tolerant to defective MPEGs. http://www.marumo.ne.jp/mpeg2/
I'm having troubles converting an AVI file to an mpeg-1 file.
I want to convert an 357MB (512x354) AVI file to an +/- 450MB (352x288) MPEG-1 file.
When I'm using the wizard I select the VideoCD and then next until the page with the file size. The file always ends up 1GB or more. What am I doing wrong?
Can someone give me a tip on how to convert the file correctly to an 450MB MPEG-1 or VCD file.
