adding different audio track to video
« on: April 16, 2010, 09:38:58 pm »
alright, so what programme is good for this trick? i mean, i recorded a film with my cam and also only audio with my mike and i want to replace the original audio track with the other one that i recorded using mike

i will also need to be able to sync it

i tried windows movie maker but it cuts the quality to 25 frames from 30 fps and i also tried virtualdub but the option for adding different audio doesn't work at all

any suggestions how to do this?

I use videopad video editor. it's basic but free and certainly does what you want.... thinking of looking for something a little more advanced though so if I find anything else I'll let you know.

hmmm, actually i've just managed to swap the audio tracks in virtualdub, but there is another problem: when i "crop" (remove the beginning and the end) and i want to save the lasting part as a video it becomes so large that it doesn't make any sense... an 8 minutes long film is shortened to about 3 mins and originally 500 mb become 4 gb wtf?

do you know how to crop the film in videopad and keep the original file size? i might check it out if it's possible

Most likely the new file is a less efficient compression codec than the old one. should be an option in settings to change that.

I always trim the start and end off videos I make, file size doesn't run away.

i found the proper option and now everything is fine... is the video compressed automatically when being uploaded on YT or do i have to prepare it myself? atm it is avi file about 200 mb and resolution 640x480, unfortunately my internet connection stopped working again...

Youtube will process it into it's own file type mucking around with most of the settings if it's not what it's after.

generally the less processing youtube has to do the better for your video.

definitely a codec issue.. it was prolly mpeg2 before and might be getting saved as no compressed now.....simple fix, to keep the original format, simply select 'Direct Stream Copy' in both the video and audio sections of Vdub then save the avi...it will keep the original format for both the audio and video




***EDIT***

Opps should have read the WHOLE thread..lol
well I'll leave it anyways in case someone else has an issue

this is exactly what i did ^^

do you know if i could get mp4 files to work with virtualdub? my mobile phone records films directly in mp4 format and not only it takes less space but also provides better quality than my regular cam
