Here is what I am working with. It is an MPEG with a FRAME size of 352*288, however, the ACTUAL VIDEO takes up only 352*192 (48 pixels above and below form a black border).
Now, can I change the FRAME size to 352*192 (cropping 48 pixels off from above and below)? Will this reduce the file size slightly? I have tried using TMPGEnc but the best I've managed is to remove the borders and have the video stretched to fit the 352*288......which defeats the point!
I am NOT trying to create any standard file type (VCD, SVCD, etc)......all I need is a file that can be played on my PC, so I am not fussed if the settings are not standard. I am mainly doing this for practise and experience.
Please note, I do not want the final video to be stretched, just the same original MPEG without the black border above and below.
I do a Q though. The bitrate of the MPEG is 1150 (CBR). If this remains unchanged will my movie be of the same size irrespective of wether or not the frame size has changed?
Let me clarify. I have 2 possible ideas about how this works.....could someone tell me which is correct - if either?!
1. Changing the frame size from 352*288 to 352*192 reduces the number of pixels by (192/288 = ) 2/3 of the original amount. This would mean the file size should drop since there are less pixels.
OR
2. Although changing the frame size reduces the number of pixels, this will not change the file size because the BITRATE was kept the same before and after (here it is at 1150kbps). In a crude way the difference can be thought of as simply meaning that the bitrate is now spread across fewer pixels (a lay-man's analogy). So, to reduce the file size I can reduce the BITRATE to (192/288 = ) 2/3 of it's original size (ie. from 1150 to approx 766kbps). This will keep the video quality the same since the BITRATE PER PIXEL is the same as before.
Actually the bits go where they are needed,very little bits go to encodeing the black borders , some go to creating the picture and some go to the complex part if the picture,so cropping the black off won"t decrease the size of the file very much, and decreasing the bitrate will just decrease the quality...I hope this clears things up a bit....
Minion is right. Very little of the bitrate is allocated to the blackborders, so you won't see a marked reduction in filesize.
I always crop out the black borders before I encode, this is just to reduce the enocoding time as there is little point in re-encoding the black borders.
You are also correct that if the bitrate is the same before and after cropping, the file size will remain the same.
Reducing the bitrate will also have detrimental effects on the quality.
If all you are trying to do is reduce the file size while mantaining quality and plan to play the file on your PC only. Then my advice would be to encode your movies to DIVX 5. This will maintain the same quality at smaller file sizes.
i just wanted to know if this program can get rid of subtitles when you encode for vcd.this program is awesome i do all my movies to vcd and they work great.if anyone knows how to make the picture sharper when encoding a movie that would be nice to know thanx!
If you want to make your VCD sharper then double click the 'Sharpen edge' filter under advanced.
If you just want to increase the overall quality then just up the bitrate.
DVD2AVI 1.76 tells me this:
Aspect Ratio: 16:9
Frame Rate 25.000 fps
Video Type: PAL
Frame Type: Progressive<<
Audio Format DD 3/2 448
TMPEnc 2.54.37.135 tells me this in the advanced tab when I load up the .d2v file:
Video Source Type: Interlace<<
Field order: Bottom field first(field b)<<
Source Apspect Ratio 4:3 625 line PAL 704x576
I get the three possible answers! The big question is "Is my VOB interlaced or not and if it is, is it top field first or bottom?"
Generally speaking all dvd"s are interlaced,but to find out you just have to look at the movie it self..just load your d2v file in tmpgenc and go to the "advanced settings" to "de-interlace" and scan through your movie especialy at high motion parts and look for "interlace "lines, you will know them when you see them ,it will look like there are lines jutting out of the regular outline of the movie,but with dvd2avi ,if you were to make a avi file from your vob files, some codecs have the option of makeing the frames of the movie progressive.....
Sorry minion, but there are no interlacing artifacts on a PAL source. This only happens on NTSC sources which have 3:2 pull down added.
Actually all DVD's are progressive it's just that pulldown is added to make it an interlaced source.
So both Bitrate viewer and DVD2AVI are right, but it's strange that DVD2AVI has reported progressive if it's a PAL DVD as it usually reports 'Interlaced'
TMPG usually detects whether it's interlaced or not but doesn't usually detect if it's top or bottom field first.
If you want the definitive answer trust Bitrate viewer for your answer as it's usually always right.
This is the real output format.
In any case seeing as you are converting a PAL source these settings won't make much difference to the output and are really only necessary to worry about when converting NTSC sources. (What a joy to live in the PAL world)
Hi,
I have a clip that once converted to VCD or SVCD is missing the audio in a section of the file. I tried converting straight from the orig. file and also extracting the audio and specifying the wav file as the audio source but both produced the same result. The orig. file is fine. I used only default settings except "noise reduction". please reply offlist to mironmizrahi@yahoo.com
I have a 1.300 MB movie, captured with a TV card in Video CD-format:
- Type: MPEG1 -
- Video: 352x288, PAL625, 1.05MBit/sec. -
- Audio: 44.100 Khz, 16 Bit, Stereo -
After I tried to cut the movie into 2 pieces the sound isn¡t in sync.
Tried different settings in TMPGEnc without any positiv result.
Hope you can help me.
de-multiplex your mpeg file and see if the audio and video file are the same length, and if they are different lengths then that is your problem,then you can use a audio editing program like "cool edit" to stretch of shring you audio file to the exact same length as your video file and then multiplex then back together, then your file should be in sync.This is a common problem with captured files.....
Another capture problem.
If the original MPEG is in sync then my advice would be to re-multiplex the file and then check for A/V sync. If it's ok then cut it and it should turn out fine.
If it becomes async after multiplexing then I would use BBMPEG to mutiplex the file and use it's A/V delay feature to correct the sync.
What do you mean by crop, do you mean change the frame size?the only way I know how to is to re-encode your mpeg file to the frame size you want,or you can use "dvd2avi" it has a cropping feature that you can use to make a project file with the new frame size and then you can encode the "d2v" project file in tmpgenc and have the ouput image be the new frame size.But the first sugestion would be faster......
It's impossible to crop an MPEG or any other video file for that matter without re-encoding. Cropping means you are changing the physical characteristics of the file and therefore would need to to re-encode.
I have answered this question in your other post. I don't understand what you are trying to achieve when you say you want to produce an MPEG without black bars without re-encoding.
If all you want to do is convert your VOBs directly to an MPEG2 file without changing it in anyway then check your other post as I have posted a link to VSTRIP which will allow you to do exactly that.
So was this the message you mentioned that was deleted?
Anyway, it is not a VOB that I am trying to play with. It is an MPEG which I have and want to reduce it's size.
I have realised that it was stupid to think it can be done without re-encoding it. So how can I be sure that it is re-encoding using similar settings so as to not reduce it's video quality?
I am using AVI2MPG2/bbMPEG to crop the MPEG file I have, hopefully I can find a way to stop it form crashing (need to play around with cos it worked for a small test file I used, but crashed on the main file).
I'd just like to thank both of you guys (Minion and Ashy) for between you replying to all of my posts.
Well the simple solution is to use TMPG for cropping. TMPG contains all the tools you'll ever need to create high quality MPEGs, you just need to look for them.
BBMPEG won't give you as high a quality encode as TMPG so I'd forget all about using BBMPEG for encoding and cropping.
Open TMPG and click the 'setting' button on the right then under the 'advanced' tab tick 'clip frame' then double click it. Here you will find options to to crop and resize your MPEG.
After cropping you will have to re-encode. If you wan't to keep the quality of the file you need to examine the original file to find out it's details so you can encode to MPEG2 using the same resolution and a reasonable bitrate to keep the quality.
Is there a way to convert files, while retaining the accurate aspect ratio of the movie? I did look in the preferences of this software, but did not see anything I could change to make it happen. If any one knows of the way to accomplish this, please post.

It depends on the source and the output you wish to view on.
What is your source aspect ratio and what do you intend to view the result on, a 4:3 TV or 16:9 TV
Usually if your source is 16:9 and you intended output is 4:3 TV then you would simply choose 16:9 as your input souce aspect ratio and choose 'Full screen(keep aspect ratio)' as the arrange method and choose 4:3 as the output.
Yep, happens to me all the time and is flaming annoying.
Especially as some of them are quite long replies.
I don't know why it happens because my posts don't contain links to illegal softare or anything offensive, so if it's the moderator or whoever is supposed to run this BBS, I wish they would just leave it out.
I have a problem with TMPGEnc v2.54a and was wondering if anyone had experienced the same or come up with a solution?
I have a large MPEG2 file that I am converting to a VCD (MPEG1). If I convert the whole file then everything is fine. The problem occurs if I choose a source range. If I set up a source range to run from the middle of the movie until the end then the resulting MPEG1 file appears to be frozen on the first frame with no sound for about 8 seconds. Then the sound and video carry on as usual. The video and sound is in sync and everything OK, except that I appear to lose 8 seconds of the movie at the beginning of this MPEG part!
If I convert the whole MPEG2 to MPEG1 and then use the split option within the MPEG Tools then this works OK (however of course it is an extra step that takes time and additional hard drive space).
Has anyone else encountered this problem with source ranges? Anyone have a solution?
On the occations that I use "tmpgenc" for encodeing i use the source range feature..And the only problem I have ever had was once in a while I would get a sync problem but usualy it works great..Is the problem with that one file or every file cuz maybe it has to do with certain files..
I downloaded an AVI file which plays good on my PC. When I try to convert to mpeg so I can do a video CD. The MPEG file sound is fine but no picture. on the mpeg file. What am I doing wrong?
It's not possible to clip black borders out of a video stream using direct stream copy.
Direct stream copy means that the stream isn't physically changed in any way.
To crop the black bars out of a video stream you would be changing the stream physically and can only be accomplished by re-encoding.
Neither can Virtualdub accomplish this. It would have to be set at Full processing mode to do what you ask.
If what you are trying to say is you wish to convert the VOBs to MPEG2 directly without changing anything in the video stream then there are a few programs which can accomplish this.
Probably the best is VSTRIP.
VSTRIP can convert all the VOBs to a single MPEG2 file and extract the ac3 if you wish.
I have the following problem: I ripped a DVD with three short videoclips using CLADDVD. Next I use DVD2AVI 1.86 to create the d2v file and the audiofile which in this instance is an mpa file with name NN delay -80ms.mpa
Next I encode using TMPGENC 2.54a to create the mpg file.To make TMPGENC recognise teh audiofile I choose allfiletypes and then the mpa file.
The result videowise is OK but the audio is shorter than the video and from the beginning you hear at the same short interval like a veryshort part of the audio is missing.What can be the reason?
Should I convert the mpa to a wav file?
I will try this tonight.
You should have ripped to a wav file not an mpa file.
DVD2AVI is one hell of a frameserver and is the best tool there is for the job, but it's audio capabilities aren't too good as far as sync goes.
Also I would use smartripper to rip your movies as this will automatically create the d2v file for you which means you only need to rip the audio.
The fastest and most reliable program I have found for this is VOB2AUDIO.
Rip the audio again with VOB2AUDIO as you will still probably have sync problems when you convert the mpa to a wav.
Once you have ripped the audio to a wav with VOB2AUDIO put that into TMPG on it's own and choose 'Audio only' as the stream type in TMPG then multiplex the resulting mp2 with your already encoded movie.
One other hint, there is a program called MPEGDJencoder which can convert wavs to mp2 audio about 5x faster than TMPG.
I tried smartripper but after starting the program searches the key a couple of times, then I get a msg Quit ripper?.When I push yes the program is ripping anyway, so it seems. As I did not trust this behaviour I tried CLADDVD XP which works without any msg.
Anyway your suggestion of ripping the audio with V2OB was worse.
So I used smartripper/CLADDVD and then used BESWEET to convert MPA to WAV.
After that I use as usual TMPGENC.
Now all seems to be OK.I got rid of the audio hitches.
Strange how you got that message with smartripper. Smartripper is well known as the best ripper out there. It could be you either need to update your ASPI layer to Adaptecs ASPI 4.6 or you have installed the latest ASPI layer 4.7 from Adaptec which doesn't work with smartripper.
Ihave ripped 100's of DVD's with this program flawlessly.
Also I have never had a problem with VOB2AUDIO and is usually spot on as far as sync problems are concerned.
Anyway looks like you got it sorted, but it still leaves me confused as to how you corrected the problem by converting the original mpa to a wav as the wav should have turned out exactly the same as the mpa. Strange.
