TMPGEnc warning: file size may be larger...

[djtizzy]

is this warning anything to worry about?

would i be safe in making the output file 98.99% of disk capacity vs. 96.88%?

is 90MB or so even going to have a noticeable effect on the quality?

TMPGEnc is just being overly cautious. But if you are going to author it to DVD, you need to leave room for the authoring files. This may take about 200MB additionally. It depends on how you do your menus. You will not be likely to notice any difference in quality by dropping the size a few percent.

Another problem to be aware of is if you use cheaper DVD media, you may not be able to burn to the maximum DVD size of about 4.37GB without having problems. Some media has problems when written to the outer edge of the disc. 4096 would usually be a safe size for cheaper media.

"crate" ..Guess their engrish translator doesn't know how to spell check...

No, 90MB won't make a noticeable difference, not with 4 gigs to throw around..I don't understand why TMPGenc is constraining you to ~4100MB though, and it's about ~10% under capacity of a DVD blank. There is some packet overhead in authoring from MPG -> IFO/VOB, but not that much. I guess you've got a few choices here, either:

1) Ignore the warning (assuming you're not going too terribly over the warning sizes).
2) Just set the audio and/or video bitrates a bit lower to be safe (if not encoded or you can take time to redo it).
3) Keep the existing video if you are happy w/ it, but demux audio and re-encode to a lower bitrate to (hopefully) recover the "needed" space...Assuming you haven't set an obscenely low audio bitrate to begin with.

..And for future reference, screw TMPGenc calculations, I find that if you're either a) really good at math, or b) use a br calculator (I like VideoCalc), it be pretty much spot on everytime. Check the screenshot for details - tells you all you need to know about it really.

[edit] Damn I'm too slow . Anyway, I think unless you go hogwild, 200MB is being quite generous for the packet o/h and menus, but best to be safe I s'pose..I have to agree with redwudz on the media comment..Maybe it's best to undersize it this time, you probably won't notice ~90MB over the course of an entire DVD. You could always bump it up for future encodes if all goes well, or you're confident in your media (ie: TY and company)..Then again, you didn't specify the runtime of your video, nor the source..With a crappy source, or trying to cram an obscene length of video onto the disc may make dropping the br a problem.
