JPEG size limitation

Question

I scanned sixteen 35mm slides in using three different dpi settings to see if I could tell the quality difference on my Sony 46 HD XBR2. I am using a HP G4050 scanner with the transparent materials adapter and the 16 slide 35mm template.

 

A 300 dpi scanned jpeg resulted in an image size of approx. 750kb to 900kb

A 600 dpi scanned jpeg resulted in an image size of approx. 1.5mb to 3.0mb

A 3600 dpi scanned jpeg resulted in an image size of approx. 44mb to 70mb (huge)

 

So far the use of Roxio EMC 9 MYDVD and Classic fail with the 3600 dpi scanned jpeg. (50mb image). The burning process with MYDVD of all 48 jpegs hangs/freezes my PC and the only way out is a hard power off. I burned a multimedia CD with Creator Classic using three jpegs of different sizes and I got an image load error on my CD player with the 3600 dpi scanned image.

 

So, my questions are rather simple. What is the jpeg size limit for the different Roxio EMC suite products? Is there a maximum number of jpegs that can be burned and still stay with the media size limitation?

 

I know www.scancafe.com will scan 35mm slides at 3,000 dpi and create a DVD so I am assuming (I hate that word) that large jpegs can be played back on a DVD player. That could possibly mean that Creator Classic also has problems with large jpegs.

 

Any comments and recommendations?

3599 dpi? I certainly wouldn't wast hard drive space scanning at that .dpi.

Gramps,

 

Just a simple answer to my questions would do and please don't badger me about the scanned image size using 3,600 dpi. My scanner goes to 4,800 dpi. Yes, I will conceed on the outcome size that 3,600 is too big but there still are questions that need to be answered.

GPB: Most who do slides recommend 4200dpi as a minimum! When you are going from a postage size to an 8 X 10, you need every dpi you can lay your $$$ on! -

 

Big Dave: Some DVD Players will play a Data DVD with jpg files on it. – I have 3, 2 will, 1 will not!

 

Honestly I do not know how they covert them to a picture for your TV. – something you could try with the ones you just scanned???

 

Use Classic, set Project Properties to UDF, No Bridge. Load the jpgs into the root and burn (Read Only) to a DVD RW disc.

 

Let us know your impressions of the results, I am curious!

EMC 9 Classic indicates via project settings:

 

UDF102 or Joliet for file types

Joliet or ISO9600 for bridge

 

What are you suggesting to try Mr H.? B)

For 'bridge', do you not see 'no bridge'? Is there a scroll bar? Perhaps you just didn't scroll down to see it?

Guess you haven't scanned many slides, Bruce? Even if you don't print out enlargements, without a high DPI you will lose tons of details especially in darker areas. You also need a good scanner with high density rating like 3.8 or better. I wasted about a year scanning 3000 slides at 1800dpi which I thought was great at the time. :lol: Talk about a serious redo.

None. :lol: I STAND CORRECTED. Well, maybe sit corrected.

I found the "no bridge" drop down. :D I run with 120 dpi fonts so the scaling on some of the Roxio menu drop downs at this dpi isn't the best. :mellow: I need to buy some more DVD-RW media as I am fresh out.

 

Scanning 35mm slides at anything past 600 dpi is very, very time consuming. It took over 3 hours just to scan the template of 16 slides at 3600 dpi on my desktop PC and then each jpeg averaged 50mb. The big concern I have is if Roxio EMC 9 MyDVD can handle that large of a jpeg. So far, MyDVD just locks up my PC trying to encode that size of a jpeg. :angry: Then, only a hard power off will work. I just might have to send my slides out for scanning to a commerical business./ :glare:

I have had problems in the past with very large files. Since I'm not sure what you want to do, I'm confused with the references to bridge/no bridge for data files VS MyDVD for images (but apparently not a slide show ?) and no mention of Video Wave if you are making a slide show.

 

If you are making slide shows and want to put them on to a DVD, the files will be encoded to DVD quality anyway. You can always use something like batch convert to reduce the resolution and use those in the slide shows while putting the original high quality images on a DVD.

I tried to use EMC 9 MyDVD to create the video slide show. It works quite well on smaller jpegs but on the larger jpegs as stated above, my PC freezes during the encoding process trying to encode the large jpeg. I haven't tried VideoWave to make a slide show. I'll give VideoWave a try and report back my results.

It looks like all roads lead to the same jpeg to video encoder using VideoWave. :( I had the same PC freeze situation during the encoding process. Nothing gets written to disk and the PC is non-responsive (frozen). Only a hard power off will then work.

 

It appears that the encoder is not able to handle large jpeg files. :angry: I tried six jpegs of three different scan densities; two small (300 dpi), 2 large (3600 dpi) and 2 medium (600 dpi).

I tried the "no bridge" suggestion as mentioned above and all it did was copy jpegs to the DVD. This is not what I wanted to do. A DVD video quality slide show is my desire. So far, Roxio EMC 9 hasn't been able to handle a large jpeg from a scanned in 33mm slide during the encoding process.

 

It is interesting to note that if you rename a .vob file of 25mb to mpeg that will encode but not with a jpeg of 50mb.

Those fiels are handled differently becuase they ARE different. VOB file is already encoded as MPEG 2. A JPEG is not. Add to that MyDVD has TO RESIZE the file first. Most likely your computer isn't locked up, but churning away at resizing those files. Video DVDs are 720X480. I can tell you right now that you would be MUCH better off resizing the 35mm scans BEFORE using them in MyDVD. Photo editors have better algorthyms for that purpose. I sometimes resize my digital camera stills before using them in MyDVD.

You might try Multi-Photo Enhance and select Convert. All part of EMC 9

I conducted a couple of more tests using MYDVD and the slideshow process. The first test was with two small (750kb) jpegs and two big (50mb) jpegs. The second test was with two big (50mb) jpegs and two small (750kb) jpegs. Basically, I reversed the order of the encoding process. In both cases, the burn was successful. However, in both cases the large jpegs failed to display on either my PC or my DVD player. :angry:

 

I used a DVD+RW for all tests burned at 4x.

 

I believe that there is a unknown jpeg size limitation with MYDVD and the slideshow process when you attempt to create a video photo slideshow. I have done enough testing on this issue. QED

 

If anyone else wants to disprove my results, please do so and let me know how it (video photo slideshow) can be done. This is not to be confused with a jpeg slideshow. ;)

I shouldn't have to do that but it may be a circumvention that will work. I certainly don't want to do that with 2,000 jpegs just to circumvent a Roxio problem. Roxio has an issue that needs to be fixed.

Videowave is a video editor - not an image editor. Personally, I usually resize images before using them even images from my 6MP still camera. As I mentioned earlier, a real image editor has much better algorithms for resizing and create much better quality reductions. Same goes for enlarging.
