Brightening Video Slows It Down (help Pls!)

[vokhal]

has anyone else had an issue with the video slowing down during preview playback and recorded playback after they've brightened a video?

 

i'm using roxio myDVD 10 to burn an AVI video onto DVD. when i add the video to my menu and play it (before i brighten or edit), during the playback mode it is perfect. but as soon as i brighten it (nothing else...no other editing), i preview it again and it plays back all choppy and slow and the sound doesn't sync up.

 

i'm wondering if it's b/c the AVI file is 7 MB, and so brightening the whole video eats up all the process time?

 

i only noticed all of this b/c when i went to burn it, it took 10 times as long! so i aborted the burn to try and figure out of the video is corrupted. it's not. i can play the AVI video alone in windows media and it's perfect.

 

should i just call it a day and change the brightening mode on my TV for this one movie when i play it back on DVD?

 

again, i think the culprit is b/c i'm trying to brighten the whole video.

 

any tips or suggestions would be greatly appreciated. thanks!

By doing any editing, even just brightening, the program must re-render the entire video to a mpg2 file so that it can be burned and played on a DVD player. That is what is taking so long.

 

Also you sound like you are rendering and burning in one step. Although you did not post your computer specs, it appears that it may be marginal for this application. It would help if you do post your computer specs in your signature (My Controls at the top of this page and then edit your signature.) All your old and future posts will include this information.

 

Try rendering (encoding) to an ISO file first; chose best quality, ISO file is one of the options you get when you go to burn from MyDVD. That will take the time. Once it is finished, just copy that ISO file to a disc using Creator Classic.

 

BTW, previews are not going to be best quality. Remember you can get only 1 hour on a DVD at best quality; less than two hours with some loss of quality.

hi sknis! thanks for your reply. i am work now, so don't have access to my home computer to verify my specs, but i will be sure to post that in the future in my autosig. regarding your third paragrpah, i forgot to mention that i am actually creating an ISO file first. the movie i'm trying to burn is nearly 2 hours, and so i can't put it directly onto my DVD+R DL without saving it to my computer first as an ISO file. the delay is in the encoding process. once i select all the options (i.e. best quality, DVD 8.5GB etc.) and i select "burn" the encoding takes forever. the issue isn't so much that the preview is poor quality...it's that it is very slow and choppy and out of sync with the sound. when i left the movie alone (just some minor trimming, but no brightening or anything), i was able the ISO creation step/encoding process completed in normal time. also, both the preview and the final output played perfectly fine.

 

i guess for now (unless you have any other suggestions) i will just adjust the brightening feature on my actual TV screen. sigh.

 

but it sounds like from what you mention above, any kind of brightening or color adjustments to the actual movie require more processing than just trimming the beginning or end of the movie file. i think i just need a new computer! this one's a few years old anyways.

 

thanks for your help!

Changing the brightness is a major change! It has to be applied to each and every 720 X 480 "picture" and there are 29.97 of those for every Second of your movie…

 

The ISO is not an extra step for the computer. That is what it does before it ever starts to burn. All of the Gurus here burn this way and recommend it.

 

If you burned other DVD's and they were OK, there is no reason to assume your DL won't be. But if you have an RW why not test it by changing the brightness and cutting to 1 hour length. That will force a full re-render and RW's can be reused. (wish they made them in DL!)

 

Faster PCs will render at 1X or better. It is purely a product of your CPU speed.
