Best PNG or JPEG settings to use in Vegas, from Photoshop

[Ralph Hajik]

Hi Guys,

WOW! I’m confused. I’m using Vegas Pro8 and Standard definition, not HD. I’m presently working on a DVD project with around 2000 png pictures with video. I’m deleteing pics as I go along so I’m not using all of them. My pictures and been resized in Photoshop to 1440×960 and 300dpi which means nothing in video so I can zoom in when I want. When I move into HD, it’s like another world.

‘which rounds up to 1920 pixels. ;-)’

That’s even better!

‘Also .png files can contain a transparent alph channel where jpegs
can’t if I’m not mistaken.’

That’s why I suggested in my first reply to use PNG files for the pictures that need to have transparancy and JPG files for all the pictures that do not need transparancy

PNG files are the best format. They do not create compression losses and artifacts, and Vegas handles them without resorting to third party software. Jpgs are NOT a very good idea.

If the pixel size is changing when you change PPI (Again, it is NOT dpi. Note that photoshop shows the measurement as pixels/inch or PPI), then you have the resample box checked. That will cause an increase or decrease in pixels when you change ppi. However, you will be better to begin ignoring ppi. If you are in the resize dialogue, change the pixels demensions directly (i.e. the upper portion of the resize box). Note that, if you do that, you will need the resample box checked.

You can also type the number of horizontal and vertical pixels directly into the cropping tool. That will provide a predetermined, fixed size for the image after it is cropped. That setting can then be saved as a preset. Consider how many pixels your desired video format displays. Once you know that, I would set the photo size to no more than 2 or 3 times that size. I always then save the image as a PNG. Vegas works well with PNGs.

Scott Francis is suffering from memory problems. So everything he can do to save memory, he should do. And if you don’t take it from me that Vegas likes jpg’s as much as it likes PNGs, maybe you do accept the words from my favorite Vegas author DSE?

OK, I’ve read both links. DSE does not say that Vegas prefers jpegs. He does say that it prefers jpgs, pngs, and targa. So, I will repeat my point. Pngs are preferable to jpgs because jpgs compress the image file and introduce artifacts. Pngs are a lossless format, and are capable of preserving transparency. Certainly the size, in pixels, needs to be reasonably small, but that is true for all of the file types.

I do not understand why you think that jpgs will save memory. Are you saying that Vegas keeps a jpeg in its fully compressed state when the image is in the computer’s memory? That would be a new one for me. I certainly do not think that Photoshop does anything like that. My understanding is that jpeg compression is used only for disk storage and file transfer. It is fully expanded prior to viewing.
