Re-Rendering a project after small changes

Richard Jones wrote on 10/6/2017, 5:34 AM

I'm sorry as I know the subject has been covered before but I'm blessed if I can find it.

I completed a project of 1 hr 10min in Pro 12, rendered it, opened it to DVDA6, arranged my menu media and burnt a disc with no problem but now find that I have to replace one video event of about 20 secs and correct an Audio event of some 25 secs where the Volume Envelope had been dropped to silence sounds which are in fact needed. Is there a shortcut way of doing this or do I (as I suspect) have to go through the whole process again? And if so, can the render times be reduced (e.g. by over-writing the existing renders or by some other method)?

Sorry to be a pain!

Richard

I vaguely recall that U-Lead VideoStudio from 10+ years ago would only re-render from the point in a previous render with the same name where a subsequent change in that project had occurred - and it would do that automatically with no additional render settings needed. I really wish that Vegas Pro had that function as well but I have not seen that function in VP or heard any talk about it being available over the years.

if your rendered file is mpg, intended for DVD Architect, I use smart render.

Yes, sorry. I should have mentioned that I rendered to mpeg2 and AC3 Pro.

Re-edit your vegas project. On your Vegas timeline, create a new video track on top and put the mpg rendered file to it. Just go to the portion where you have made changes and split/cut the rendered mpg file so it makes an open space for lower video track. Render the vegas project. you should see the black screen with text No Re-compression required.

Thank you Elex. That's most helpful.

Someone has suggested deleting the rendered mpg and AC3 files and then re-rendering the whole project again before importing these new files into DVDA. As these new files will have the same identification, DVDA will be fooled into believing these are the same ones which means that the whole DVDA project (menus, media and all) will remain but with the new mpg/AC3 files in place, so saving having to re-work the whole DVDA phase again (i.e. I can go straight in and burn a new disc).

This seems to be a swings and roundabouts affair: using your method the rendering time will be very short but the whole DVDA phase will need to be re-done from the beginning whereas the other method will leave the rendering time the same but have the DVDA project in place and ready for making a DVD. Your method is probably quicker but the other one relieves me of the rather tedious (for me, at least) DVDA task.

I should be interested to learn whether you feel my thinking on this is right?

AFAIK, just the menu will be re-rendered by DVDA, not the main video. if you have a simple menu, its quicker.

Just use the TRACK MEDIA rightclick and replace. It will only be an issue if the new video is a different length.

Thank you David but I'm afraid I'm being a bit dim. Do you mean that if I do this to replace the event in the project in Pro 12 then I need only tuse "Render As" and it will over-write the first file? If so, I can see that this will be very quick but will I then have to reimport yhis into DVDA?

I am sorry, to be clearer. In DVDA there is an option on the right to select the TRACK MEDIA. You can change the video and audio file being used in the project without changing properties or name. Render your new MPEG video file and open your project in DVDA and replace the TRACK MEDIA video with this option.

Thank you David. Got it now.

Another tip, Richard. I sometimes get an error message when replacing the video media in DVDA even if the new video render is of the same length, the error message saying that the video media is in the wrong format (or similar wording). Please note however that I am using .avc rather than .mpg as the video media.

If you do get this message, the workaround is quite easy ... just delete from the folder containing the video media - or move to another folder - the additional files (e.g. .mui/.sfvx) that DVDA had created for the earlier video media. DVDA will then accept the revised video media and create a new set of additional files.

I haven't struck the error message with AC3 audio media in DVDA, though I now always rename video and audio re-renders to include the date of the render because I used to get a bit confused with render versions even when tagging the name with v1/v2/etc 'cos I'd forget to update the version number when rendering - the date has proved a little more obvious for me.

Another way to change media is to highlight the video and/or audio media on DVDA's timeline and delete - then drag the new media from DVDA's explorer window onto the timeline.

I hope that the above assists.

Cheers

Conrad

Thank you to all who helped and to Conrad for his latest tips.

In the end I decided to go down the route of deleting the mpg. AC3 and My Disc files relating to this project. I then made my editing changes to the existing Timeline (2 minutes) and re-rendered the whole project again to mpg and AC3 with exactly the same file names as those I deleted (two and a half hours). When I then opened the relevant DVDA project all the changes were in place and I was able to burn a new disc straight away. It worked well but next time this happens (let's hope that's a long time off!), I shall try the other method.

My thanks to everyone for their help.
