I've been trying to create a good image out of a 640x480 single frame capture. I use Photoshop to clean up the image via (deinterlace, color correction, smoothing). But my efforts yield a very poor picture.
Question1:
How do content providers get those crisp clear images from movies? I notice some images are 1024x768 etc. and my ospry220 is only able to capture at 640x480. But I don't think 1024x768 is going to improve the quality. How do they get such clean images.
Question2:
What is 'slide scanning'? I have a epson1250 and was wondering if using 'slide scanning' is how they got those crisp pictures? And if so, where in the world would you get slides to a movie?
I apologize for this off topic question.
Any help is much appreciated.

Hi, i want to convert an AVi which is 750mb @720x576 to an mpeg of the same size etc, but when it gets halfway through converting it, it just stops dead and sits like its idel??
I have a 41:57 avi source i want to encode to svcd. I figured i need an avg bitrate of about 2358 to be able to fit it nicely on 1 80min CD. However, using 2 pass VBR it results in a much smaller file (~755MB), while using CBR it gives a nice 785 mb file. How is this possible?
I am using TMPGenc DVD Author V 1.5.19,
I have Authored a file to VOB format from mpeg, but when I try to burn it I keep getting an 'invalid number code' error.
I have also tried to burn with nero, which also gives an error.
Is there anyway to find out where the problem is?
Thanks

How do we add selectable subtitles to a DVD? Can I do that using DVD Author? I have 2 subtitle files that works together: an IDX and a SUB file. Any help is appreciated!
Only the expensive DVD Authoring-Tools are able to do that, like Scenarist or Maestro.
Some other Tools are able to create Menus and Videos with Subtitle- and different Audio-Streams, but they can't create Menus for selecting Subtitles.
Maybe the combination of IFOEdit and DVDLab will work, but that's hard to learn stuff.
Actually, I found this program called Pinnacle Impression DVD Pro that might do it. It lists that it can do menus and subtitles. I have another question:
How do you go about making trailers? And then you can have them on a menu where you select which one to play?
I have a few movies i am trying to convert the video loads but the audio wont the movies have audio when i play them in Windows media player I have converted many movies with no problems im stuck any ideas?
When I play back my authored DVD-R on a domestic DVD player I encounter lots of stutters and jumps.
This seems to be a common problem as I have discovered from reading through this and other forums.
When the stuttering occurs the DVD player (Yamaha DVD-S520) can be heard to make unhealthy sounding noises which is quite unnerving. This does not happen on other DVD's, e.g. Hollywood type DVD's & other DVD-R's.
I created a second DVD and reduced the Max bitrate (2-pass VBR). Under 'Verify' in ReelDVD (3.0.3) it now reports the following:
Info === Verification 04-t ===
Info -- Total bitrate --
Info Main video bitrate = 7150000, data = "04"
Info Audio stream ID = 1, bitrate = 224000, type = AC-3, data = "04_1"
Info Sum of audio bitrate = 224000.
Info Total bitrate = 7374000 [ audio + main video ]
Info === Finish.[Verification] ===
The problem persists. I don't believe that it is a bit rate problem so what could be causing the trouble?
Sonic CinePlayer plays both the hard disk and DVD versions of the project OK on the computer.
In total I have 110 minutes of Video / Audio. Image Encoding Rate in ReelDVD is set to 7.0 Mbps. There is only one audio stream per track. There are no subtitles.
I don't believe it is a field order problem because the picture quality looks excellent in the parts where it does not stutter.

First I would slow the burn speed down. If that doesn't work I would try different disks. Even though Verbatim are decent disks it doesn't mean your player will be compatible with them.
I would also try out the DVD+R format to see if it's a compatibity problem with the disks.
Which software are you using to author and burn the disk?
I would definitely use a different burning program.
Roxio (Easy CD Creator 5) is NOT known for being the best burning program and don't think it's too good for DVD either. I don't even think it will burn the ISO in the right UDF format.
I would try Nero.
You would be better just burning the authored files directly with NERO's 'DVD-video' mode rather than creating an image first with ReelDVD.
If that doesn't work then try TMPG DVDauthor to author your DVD.
I downloaded a demo version of Nero 6.303 and burnt a DVD-R in DVD-video mode. I also re-flashed the Sony DRX-500UL with the latest firmware (500A_20h) before hand.
Unfortunately it made no difference :-(
So I guess it's either poor media and / or the encoded MPEG file being at fault.
Incidentally I spotted this URL: http://club.cdfreaks.com/showthread.php?threadid=61142
which suggests using the DVD-UDF/ISO option in Nero to burn a video DVD (Step 5: DVDR Burning). This mode also has the option to select "Force DVD-Video Compatability Mode (Required for XBox)". I haven't tried it yet.
That advice used to be for the earlier buggy versions of NERO that used to burn in the wrong UDF mode.
That has all been taken care of now. The XBOX compatibility mode is simply to make sure the DVD is burned as a DVD-video.
The DVD-video mode will automatically burn for XBOX compatibility and will burn the DVD in the most compatible UDF mode.
I finally tracked down the source of the problem and it did turn out to be the media, although there is a slight twist to the story.
What baffled me is how the same media from the same stock that I had used on a previous project without problem suddenly started causing the stuttering and jumping.
The evidence did point towards the media but the only difference that I could see between the two projects was the parameters used in the MPEG-2 encoding.
Late Friday I created another test disc that contained a selection of encoded files with different MPEG values, mainly GOP related.
When I played the disc it still stuttered on each of the sections. This finally convinced me that the problem was not MPEG related.
Saturday morning I decided to watch my new test DVD again. This time the disc played perfectly!
It was then that I realised what the difference had been all along. Heat!! The DVD player and Amp had been switched off overnight and in the morning they were cold.
In the last project I had only played the DVD's when the system was cold.
When the amp is left on all day, like it usually is, the heat rises making the DVD player on top of the amp hot. The DVD player also generates a lot of heat when it is switched on but that is a separate cause for concern.
After 5 minutes of playing the heat built up and the same problem appeared.
The DVD-R's I had been using were the crazy looking Verbatim (Reorder 43207) which have the printable area nearly all the way into the centre of the disc.
Towards the hub of the disc, in the printable area, the name 'Verbatim' and 'DVD-R 2x' is etched in. I think this may cause the disc to run in an eccentric manner or alter the aerodynamics of the disc. It would appear that heat exasperates the condition.
The effect is similar to sticking Neato CD labels on a DVD. Some players, mine included, have trouble playing afterwards because the disc is imbalanced and / or the aerodynamics change.
There is also another version of these Verbatim discs with a slightly different reorder number that doesn't have the printable area going nearly all the way into the centre. The manufacturer ID is the same MCC 00RG200.
I tried one of these discs and it stuttered as well, but nowhere as badly as its sibling.
I also tried three other brand of discs, those with Manufacturer ID's TYG01, RITEKG04 & PRODISCG01. They all played perfectly, even when the system was hot.
Next step is to see how each play when they are printed on. Then it's time to move the DVD player :-)
I'm using a file from DVD+ disc that has already been converted from SVCD to DVD standard.
Using TMP Author I can convert the above to an mpg file, edit, view, create chapters etc but I can't output it as It says the the resolution is non-DVD Standard (480 x 576). Is there a way of altering this res info to say 352x576? I've tried 'DVD patcher' but them TMP Author wouldn't read it at all!
I've been looking for a conversion program for quite a while, and then came across TMPGEnc. I downloaded the free version and i love it. I've been using it for about 3 months without a problem. Now I have problems. When i try to cut my converted avi, it does the first half of the movie without a hitch. Problem is, when i do the second half, it goes through all the processes of cutting, but when i go to the folder where i saved it, it comes up as just a "file". It says the file size, which is about the size it should be, but that's all. I'm really at a loss here because it worked for me before. I've tried un-installing it and re-installing, and no luck.
I don't know what to do, as I always do the EXACT same way as i do all my other files that i convert. I've tried it with 5-6 different files and always the same result.....just the first half.
I was wondering how large MPEG-2 files are in terms of file size? And how many hours it took you to convert a 1 hour movie? How about a half hour movie?
If you're using a normal DVD template, the video size is set to 720x576 (I think). If I had a downloaded movie whose size is 712x400 or even 640x360. They're both widescreen movies where the black bars have been removed. Since the resolution is smaller, won't TMPGEnc have to resize it to 720x576 under 16:9 keep full aspect ratio? Won't the video lose some quality due to the resizing? :(
Yes any time you Resize an Image so the Resolution is Larger you Loose some Quality, I personally will Not Make a standard Full D1 DVD useing Files any smaller than about 576+360 ,Smaller resolution files I usually Put on DVD useing the Half D1 DVD standard or the Sif DVD standard....
Hi. I know that when I convert to MPEG using the "Output to MPEG" feature, there is a checkbox I can check to shut down after the conversion is complete. But does it shuts down only TMPGEnc or both the program and the computer? Because I have a feeling my computer was on all night and I wanted it to shut down plus I checked the option. :(
