I have some video which was shot using multiple aspect ratios. I have no problem using TMPGenc to get any of the individual parts to work, but I'm not sure what is the best way to use them together.
Suppose I have a video that starts off in 4:3. That's pretty simple. I know how to create an MPG of that from my AVI, and it's fairly trivial to use Source Range to get just the 4:3 part. If the next part is 16:9, likewise I have no problem with the correct settings or getting the source range.
What I want to do, however, is to be able to specify that the first part is 4:3 and that the second part is 16:9 and come up with a single MPG. I'd like to know how to do this with either TMPGEnc or another tool if it's more appropriate to splice them later.
Also, since I'll probably be putting much of this on a VCD, I don't know if it would get around my problem to just put several consecutive MPGs on the VCD. I haven't tried that or read anything about it so I don't know that it's even an option. If it can be done, I'd like to know. But even if it's trivial to do it that way, I'd still like an option with a single MPG for use on the web.

Hello, wow! First, why would you want to have all kinds of various video aspects in one MPEG movie? Just asking. It can drive some people nuts watching it, and some DVD players may wonder what display aspect they are to use. I can make mine play all 16:9 as 4:3 for a default, and vice versa. Howabout converting everything to either a standard 4:3 or 16:9 video aspect? Then you don't have any problem.
You could encode each video section into an MPEG file, then use the MPEG tools in TEMPEnc to join the file together into one monster mixmash of video aspects or common video aspect, as you please.
Actually, I wouldn't want to have multiple aspect ratios in one video, at least most of the time. The problem is that I already do. My video camera gives me a choice of aspect ratios. 4:3 is fine for lots of every day things. If I tape a school play or something, switching to 16:9 makes a lot more sense. If I started out in 4:3 with ,aterial that logically belongs together, then I'm in this situation.
Unfortunately, showing it on a standard TV will show the 4:3 fine and the 16:9 full screen with everybody looking too thin. Creating the different parts correctly was no problem. I just looked at the MPEG tools and it now seems self explanatory. I haven't used them before. I just upgraded from an old copy and handn't used them on the old one, if indeed they were there. Thanks.
Changing aspect ratios in the middle of a file (or DVD-Video title) would be highly unusual. Even if legal, players would probably be inconsistent.
Decide whether you want the 16:9 material letterboxed into an overall 4:3 production or if you want 4:3 "windowboxed" into a 16:9 production.
Split the material and use resize/mask in virtualdub or TMPG to convert the "non-standard" clips to production ones with black bars. Encode each in the production ratio and merge. Or, join with an editor before encoding if audio sync ends up bad).

Actually, it's surprisingly common. Except that in cases where you see it, it's not truly different aspect ratios. What you end up seeing is a consistent aspect ratio with black or white bars for the "letterboxed" portion that are really part of the video with the non-letterboxed portion. Or to put it another way, truly doing it is highly unusual as you say, but making it appear that way is not uncommon.
In the case of video cameras that offer multiple aspect ratios, it's also very easy to do. The camera doesn't care what aspect ratio was used on the tape before you switch since it's not a file, per se. If you use a 1394 cable to transfer it to a computer, then you get an anamorphic AVI file and programs will handle it consistently. Assuming that there is a 4:3 display, they will show the 4:3 correctly with the rest stretched vertically, or vice versa if displayed in widescreen. It's not the inconsisent way in which it will be displayed that's the problem. It's that the consistent way in which they are displayed is not useful. Which is why it's best not to do it in the first place. But in real life, if I'm about to tape something that makes much more sense in widescreen, I'll switch in the middle of the tape and now I know how to correct it later.
hello again
i have gone through virtual dub went to save wav however the wav creted does not play and just shuts down the programme im running it in is there anything i can do or is just bad divx file?????
thankyou.
If you have a DIVX file, why not run it through DVD2AVI to get the MPEG audio file which will be have an .MPA extension, I believe. You can convert that MPEG audio file to a .WAV file using one of the many programs available on the web. Or, you can use the resulting files and use TMPGENC to encode the video to VCD.
The audio you are trying to extract from the DiVX movie may not be compatible with Virtualdub. It is likely to be Ac3 which is not compatible with Virtualdub.
To extract the audio from the DIVX to a wav use AVIMUX.
I'm using AMD Athlon 1800+ & DDR RAM 256MB running on Win2k SP 2. When I tried to encode a 13GB AVI to VCD PAL format using best quality and the system always halted half-way thru. Please advice. Thanks.
Hello, how much hard drive space do you have. Is your Windows Temp directory full of garbage files? Or, your network temp directory full up, too? I would run a good system diagnotic tools program such as Norton Utilities or Ontrack to clean up the registry, temp directory, space hogging files that aren't needed, etc. Especially, if you've never done this before.
Windows sub directories are limited to the number of files that can be contained in them, which is why most power users put the working Temp directory under the C: root. Windows then allows for almost unlimited garbage files here, and you can easily see and clean them out.
If the File stops Encodeing at the same spot every time then there could be a Glitch or error at that point of the file..You can try encodeing up to were it stops then start encodeing again a few frames after were it stoped then join the 2 parts together with the merge & Cut....

Hi,
Thanks for your reply. I don't think is due to hard disk space. I have 60GB empty space, that should be more than enough.

Hi,
Thanks for your reply. I'm using Ulead VideoStudio 6 and using "DV Video Encoder -- type 1" to generate the AVI file. The file actually does not accept by V-Dub and the error message is "cannot locate decompressor for format 'dvsd' (unknown)". Could it because of the "DV Video Encoder -- type 1"?
FYI, the output for "DV Video Encoder -- type 1" is 24 Bits, 720 x 576, 25 fps and DV Audio -- PAL, 48.000 kHz, 16 Bit, Stereo. Thanks.
Has anyone tried using an AVI or MPEG produced in
VideoWave 4, imported into TMPGEnc for DVD authoring?
It is not clear from VW4 if the format is Type-1 AVI
(w/ the known problems), however, there is an
option for Cinepac codec for Windows AVI in addition
to the DV AVI which I am guessing is type 1. Any experience
out there?
You get this error when you Haven"t go all the Tmpgenc Files in the same folder...All the Tmpgenc Files have to be in the same folder and one of tyhose files has to be the "P3P Package.dll"....
My project is an old wedding video, i used Premiere 6 to edit clips and deleted the original audio and replaced it with various music files. I compressed this to mpeg1 vcd-non standard via Avisynth frameserver with the following specs:
Tmpeg 2.57
352x240 29.97 fps
CQ min 1500 max 3000 quality 75
VBV buffer 40, Motion Quality: High quality
GOP Structure - don't think it will matter
Audio - Stream Type MPEG1 Layer II - (no idea why i used II instead of I)
44100 stereo 224 bitrate
The first song was compressed perfectly/flawlessly the second up to the fifth song there was a bit stuttered on the first few phrases and gets better until the song ends. Percentage wise about 3-5% of the audio is stutered.
This could have been acceptable, however i produced the video to be a romantic theme but the stuttering distract my viewers and ruin the rhythm of the story. I made another compression this time doubling the min to 3000 and max 6000 and audio bitrate down to 160 everything else is the same. What transpired is that the first song again is flawless, the rest of the song has stutters but instead of the first part it moved somewhere in the middle of the song and the stuttering increased to about 10%.
Im lost where else i can adjust to improve the audio. BTW in PC playback its perfect. My DVD/VCD player is Pioneer DV-C503.
The DVD player certainly can't handle the non-standard VCD format that you have choosen, and is getting totally confused with the data rates. To guarentee that the DVD player will work properly encode the VCD so that you don't exceed a video encoding rate of 1150 bps. A CQ_VBR setting of 1150 for MAX, 0 for MIN and 100 percent quality should suffice and allow you to get about 90 to 95 minutes of video compressed enough to fit on 1, 80 min CDR.
I'd also check your owner manual for the DVD player for its specs and check with Pioneer as well. Some newer players will handle some of the weird, experimental bitrates that people are trying to encode into VCD, but to ensure the maximum capatibility 1150 bps will suffice for encoding VHS tapes to digital. Unless you have a lot of superspeed, hiaction, graphics special effects going on, no one is going to notice.
Also, the Noise Ffilter setting of 8, 2, 8 or 4, 2, 4 (depending on how noisy the video is) with High Quality set does an excellent job of smoothing and helping the resize filter crunch the file a bit more than without the filter. It does slow encoding down up to 400 percent, but the results are worth the effort.
Your problem is probably linbked to your bitrate. Your player doesn't seem to be able to handle the max bitrate you have chosen. A lot of DVD players have a limit to the bitrate they can handle. It is probably limited to 2600kb/s. Drop your max bitrate down. You can find a good list of what DVD players can handle at VCDhelp.com in the DVD player list. Your player will probably be listed.
Also another important point is the VBV buffer size you have chosen. 40 is too low for the bitrate you are using. The VBV buffer size has to rise with bitrate and 40 is for standard VCD. The buffer size you should be using should be at least double that. About 112 should be ok.
If you set it to '0' then TMPG will automatically chose the appropriate bitrate for you.
Hello, i relatively new to this program. I have an 800 meg mpg file. I want to put on 2 cdr...cutting the first half was really easy...however for the second half... it always gives me 73 megs file instead of a second 400 megs file...no matter where i set the start and end cursor...why....been trying for hours :(
Hello, you didn't say which version of TMPGENC that you are using. But, MPEGS aren't really designed to be diced and chopped, split and hacked, TMPGENC does a great job, but somethings things can get really messy depending on how the MPEG is encoded, structured, etc.
Why don't you just encode the video into 2 sections with the encoder instead of the MPEG tools? Just set the start and end marks for the section to encode and voila! Yes, it may take longer but it works for everytime. Since you have the first half cut with the tools, just encode the second half with the encoder and you're done.
Especially those movies that you know that you'll have to split. Just encode each section into 80 minute chunks, or thereabouts. Most movies have fades to black where commericals will be inserted at reasonable breaks, so you may have a fade close to 75 or 78 minutes, etc., etc. throughout the movie. So, you actually do 2 or 3 encodes of the various sections. Saves the hassle of trying to use the MPEG tools after the encode.
I used the wizard in TMPGEnc and reduced the Average video bitrate and the Audio bitrate so that the Estimated file size would be 694MB. But, after I encoded the AVI, the resulting MPEG was 986MB. Did I miss something?
There is a Bug in this Version if Tmpgenc That will not let you lower the bitrate lower that the standard VCD bitrate...If you use the Muxer of an older version it will take the extra Padding off the file so it will be smaller...
Hello. If you want to get a 90 minute movie onto an 80 minute CDR, try a CQ_VBR with 1150 MAX and 0 MIN with 100 for Quality and lower the audio bitrate to 128 Kpbs.
But yes, normally an 89 minute VCD at 1150 Kpbs video rate and 224 Kpbs audio rate won't fit onto an 80 minute CDR. If you have just 9 minutes to crunch down, just reduce the audio rate first to 128 Kpbs. There are various calculator programs that will allow you to play around with video and audio bitrates. There's an equation on this site for simple VCD guestimates, and other programs can be found by just doing a google search, or just go to VCDHELP.COM to start learning about this topic from the ground up.
I agree, reducing the audio bitrate to 128kb/s and using the CQ VBR method and also overburning to 82mins, you should be able to fit this 89min movie on to 1cd even though the quality will leave a lot to be be desired.
Standard VCD bitrate is pretty crap to begin with and reducing it any further will make it worse.
The CQ method shouldn't make it any worse than standard VCD though, but my advice would be to split this movie to 2 disks and increase the max bitrate to 3,500 using the CQ method.
